The active mainnet remains on v2.0.0.6; v2.0.0.7 never +saw a public release, and the work that was scoped to v2.0.0.7 is +folded into v2.0.0.8 along with the masternode voted-consensus feature +and an accumulated body of reliability and correctness fixes. + +For the user-facing summary, see `release-notes/v2.0.0.8.md`. + +--- + +# A. MASTERNODE + +## A.1 Consensus — voted-payee mechanism + +### A.1.1 Headline: Masternode Voted Consensus + +v2.0.0.8's central feature is **masternode voted-payee consensus**. In +v2.0.0.6, the masternode paid in each block was selected locally and +could differ between nodes, with `vWinning` (`mnw` P2P messages) as a +loose coordination layer. v2.0.0.8 replaces this with an explicit voting +protocol: masternodes broadcast signed queues of upcoming payees; nodes +tally per-position votes; a supermajority of chain-derived eligible +voters makes a payee canonical for that height; +`GetEnforcedPayee` gates block validation against it. + +Activation is height-gated +(`GetEffectiveVotedConsensusActivationHeight()`), with a per-network +floor and an optional `SPORK_15` override that can only *lower* the +activation height, never raise it above the floor. Below the activation +height the legacy `GetBlockPayee` path remains authoritative, so the +change is inert on existing chain history and during the pre-activation +period. + +### A.1.2 M1Q queue-based voting (final mechanism) + +The single largest change in v2.0.0.8. The voted-consensus mechanism is +built around **per-masternode ordered queues**, not per-height +single-payee votes. + +**Mechanism.** Each masternode broadcasts a signed +`CMasternodeVoteQueue`: an ordered list of the next `VOTE_QUEUE_LENGTH` +(= `VOTE_LOOKAHEAD` = 10) payees, computed by deterministic +forward-simulation of the rotation. The simulation replicates the +existing chain-derived ranking exactly (eligibility by collateral +confirmation depth; rank by last-paid-or-confirm height, smallest +first, tie-break smallest vin) and, crucially, **advances each chosen +payee's simulated last-paid height before picking the next position.** +That forward-mutation is what the per-height path could not do — it +removes the lag that produced the §A.1.5 streak. Because every honest +masternode runs the identical deterministic simulation, all queues +agree position-for-position, so per-position consensus is trivially +unanimous and the streak is structurally impossible. + +**Consensus read.** `GetEnforcedPayee` → +`GetCanonicalWinnerFromQueues`: gated by a commit point +(`currentTip ≥ targetHeight − VOTE_COMMIT_BUFFER`, buffer = 3), a +voting-eligible floor (`MIN_ENABLED_FOR_CONSENSUS` = 5), and a +per-position supermajority tally over the most recent queues, with +position 0 of the queue broadcast at height *h* supplying the payee for +*h + 1*. + +**Wire / propagation.** New `mnvotequeue` / `getmnqueues` P2P messages +and inv type; queues stored as `mapQueues[nQueueHeight][voterVin]`; +pruned behind `VOTE_PAST_HORIZON`; erased on disconnect; equivocation +tracked across the format change. Pre-M1Q peers silently drop the +unknown command. A new `CMasternodeMan::GetQueuePaymentSnapshot()` +takes a single-lock snapshot of all MN payment state for the simulation +(honours the established lock order; does not call `mn.Check()` — +deterministic chain-derived input only). + +**Compatibility.** NOT a rolling upgrade once voted consensus is +active: `GetEnforcedPayee` reads ONLY queue consensus once active, so +a mixed M1Q/legacy fleet under enforcement would disagree. All nodes +must upgrade together before activation. + +Touched files: `cmasternodevotetracker.{cpp,h}`, +`cmasternodevotequeue.{cpp,h}`, `cmasternodeman.{cpp,h}`, +`cactivemasternode.{cpp,h}`, `cblock.cpp`, `main.cpp`, `net.h`, +`rpcmnengine.cpp`, plus serialization plumbing in `cdatastream.cpp` and +`serialize/{base,read,write}.cpp`. + +### A.1.3 Determinism of the canonical winner + +Two determinism defects in the original per-height +`GetCanonicalWinner` were fixed during the consensus implementation +(retained in the queue path because the queue producer reuses the same +ranking): + +- **Denominator.** The supermajority threshold was computed against a + live `CountEnabled()` call — a value that varies between nodes and + over time. Replaced with a deterministic, chain-derived + eligible-voter count: `CMasternode::IsVotingEligible(N)` plus + `CMasternodeMan::CountVotingEligible(N)`, both functions purely of + the voted height `N`. + +- **Unique winner.** The original loop returned the first payee in + `std::map` order that cleared the threshold — which (a) is + not necessarily the most-voted payee, and (b) never checked whether + *two* payees both cleared. The corrected logic requires a single + payee with a strict supermajority; if two or more clear, the result + is AMBIGUOUS and no winner is named. + +New constant `VOTER_ELIGIBILITY_DEPTH = 17` (`masternode.h`). + +### A.1.4 Vote-payee determinism (PB-INFLIGHT removed) + +An earlier patch (codenamed PB-INFLIGHT) had added an "in-flight vote" +fold to `FindOldestNotInVecChainDerived` that bumped an MN's effective +last-paid height based on node-local in-flight vote tally state. This +made the payee a node *votes for* depend on node-local state and +produced a stable divergence on testnet (a persistent 5/2 vote split +along the network boundary, with both clusters internally consistent). +A consensus input must be a pure function of the chain, never of +node-local state. PB-INFLIGHT was removed; `GetConsensusCommittedHeights` +(its only-caller helper) was removed. + +With PB-INFLIGHT removed, `FindOldestNotInVecChainDerived` is once +again a pure function of `(masternode list, last-paid cache, +referenceHeight, activation clamp)`. Confirmed on testnet after +removal: `getvoteinfo` from a local node and a remote VPS at the same +height return the identical canonical payee and the identical voter +set. + +### A.1.5 Vote-staleness payee streak — fixed structurally by M1Q + +The post-activation soak surfaced a recurring short payee streak +(observed as 3-streaks on the 7-MN testnet fleet), the streaking +masternode advancing one rotation position each cycle. + +**Mechanism**: the per-height payee selector ranked on +`mapLastPaidHeight`, which is written only when a block connects, while +the vote/selection for a height runs `VOTE_LOOKAHEAD` blocks earlier. +The selector's last-paid view was therefore ~`VOTE_LOOKAHEAD` behind +the height it selected for, so a masternode was re-selected for every +height in that lag window until its own payment connected. + +**Severity:** consensus-SAFE — the selector was a pure chain function, +all nodes agreed (7/7 every block through the crossing), no fork. It +was a FAIRNESS defect. + +**Resolution**: the M1Q queue redesign (A.1.2) is the structural fix. +The streak's root cause — a per-height vote computed from a last-paid +view that lagged the selected height by `VOTE_LOOKAHEAD` — is +eliminated by broadcasting an ordered queue of upcoming payees computed +by deterministic forward-simulation, in which each chosen payee's +simulated last-paid is advanced before the next position is picked. + +### A.1.6 PB-16 clamp tie-collapse — removed + +A pre-activation last-paid clamp in `FindOldestNotInVecChainDerived` +was normalising every pre-activation last-paid value to +`activationHeight - 1`. Multiple masternodes thereby collapsed to one +identical rank key, TIED, and the smallest-vin tiebreak froze +selection on one MN for ~`VOTE_LOOKAHEAD` blocks — producing a +period-`VOTE_LOOKAHEAD` streak whenever a PoS stall straddled the +activation height. + +The clamp was removed entirely. `mapLastPaidHeight` stores block +HEIGHTS, which do not go stale with wall-clock time — only with block +progression — so last-paid ORDER is correct in every epoch with no +normalisation. The never-paid fallback was changed from `paidHeight 0` +to the masternode's collateral confirmation height, so never-paid MNs +do not tie at 0. + +Confirmed at the testnet activation crossing: the clamp-free selector +rotated cleanly across the activation boundary. + +### A.1.7 `fMnAdvRelay` enforcement gate — removed + +`CheckBlock`'s voted-payee enforcement was gated on **two** conditions: + +``` +if (nMasterNodeChecksEngageTime != 0 && fMnAdvRelay) +``` + +`fMnAdvRelay` is set from a config option `-mnadvrelay` defaulting to +**false**; no node sets it. The flag originated as the toggle for an +abandoned "masternode advanced relay system" (`version.h`: *"Unfinished, +not used"*) and was repurposed as the enforcement gate without being +renamed or documented. The consequence: voted-consensus enforcement — +the headline feature — could never engage, on any node, regardless of +activation height. It was a permanent dry-run. + +The four `cblock.cpp` enforcement-gate conditions drop +`&& fMnAdvRelay`, becoming `if (nMasterNodeChecksEngageTime != 0)`. The +strict checks additionally gained a devops-fallback allowance and a +loud unconditional NOTICE when a devops-fallback payee is seen +at/after activation. The `fMnAdvRelay` extern, definition, +`-mnadvrelay` config read, help text, and the unused +`MIN_MASTERNODE_ADV_RELAY` sentinel constant were all removed. + +**Release lesson recorded:** consensus enforcement must never ship +gated behind an undocumented flag, still less one named for an +unrelated abandoned feature. + +Touched files: `cblock.cpp`, `util.h`, `util.cpp`, `init.cpp`, +`version.h`. + +### A.1.8 Engagement and vote-payee agreement + +Four fixes that take the consensus machinery from "present but inert" +to "engaging correctly": + +- **Deterministic vote payee.** `BroadcastVote`/queue producer derives + the payee from a `referenceHeight` that is a pure function of the + voted height (`forHeight - VOTE_LOOKAHEAD - REORG_DEPTH_BUFFER`), so + every masternode votes for the same payee for a given height — + regardless of where each individual node's chain tip happens to sit. + +- **Chain-derived candidate pool.** `FindOldestNotInVecChainDerived` + gained a `bool fChainDerivedEligibility` parameter (default false). + The vote path passes `true`, selecting candidates by + `IsVotingEligible` rather than the live `IsEnabled`, consistent with + A.1.3's denominator. + +- **Same-IP connectivity.** `OpenNetworkConnection` rejected a second + connection to an IP already connected, via an IP-only + `FindNode((CNetAddr)addrConnect)` term. On a testnet (and any setup) + with multiple masternodes behind one IP on distinct ports, this + prevented all but one from connecting. The IP-only term was removed; + port-distinct peers on a shared IP now connect. + +- **Staker readiness gate.** `ThreadStakeMiner` now checks, before + `CreateNewBlock`, whether voted consensus is active for the next + height and — if so — whether this node can actually produce the + voted payee. If it cannot, the staker DEFERS (logs and sleeps) + rather than mint a block on the legacy payee that the vote-aware + fleet would reject. After the M1Q transition the gate was retargeted + at `GetCanonicalWinnerFromQueues(tip+1)` — the same source the + validator uses — fixing an indefinite defer that had stopped the + PoS staker from resuming after the M1Q switch-over. + +### A.1.9 Vote propagation — relay-before-validate (with security split) + +`ProcessMessageMasternodeVote` (the `mnvote` handler) originally +dropped a vote *and failed to relay it* whenever the receiving node +did not yet have the voting masternode in its `mnodeman` list. A node +with an incomplete masternode list — most importantly a non-masternode +node such as the PoS staker — was therefore a vote *black hole*: it +neither recorded nor forwarded votes. + +Fixed by **relay-before-validate**: the handler is reordered so the +cheap checks (`AlreadyHaveVote`, vote-height window) and the `inv` +relay happen *before* the masternode-list-dependent voter lookup and +signature check. The signature is still fully verified before the +vote is *recorded*; relaying an unverified `inv` only costs peers a +`getdata` round-trip, and every node validates independently before +tallying. + +A subsequent audit found that the bare relay-before-validate would +have opened a **vote-flood amplification DoS** for known-voter junk: +a junk-signature vote with a fresh hash and a real voter vin would +have propagated network-wide. The fix is a **relay split**: +relay-before-validate is kept *only* for the genuinely-uncheckable +`voter == NULL` case (preserving the black-hole fix); when the voter +*is* known, relay happens *after* `CheckSignature` passes. With +amplification handled, the bad-signature score is lowered `100 → 5`: +still rate-limiting against a genuine bad-signature spammer, but no +single stale-key or config-fault event bans an honest peer. + +This handling is preserved through the M1Q queue path (which also +applies the relay split principle to queue broadcasts). + +### A.1.10 Validation hook — `GetEnforcedPayee` + +`GetEnforcedPayee(nBlockHeight, payeeOut, vinOut)` (`cblock.cpp`) is +the validation hook. Three regimes: + +1. Before the activation height — defer to legacy + `masternodePayments.GetBlockPayee` (the v2.0.0.6 `vWinning` map). +2. At/after activation, consensus formed — return the canonical voted + payee from the vote tracker. +3. At/after activation, no consensus yet — **permissive fallback**: + behave as pre-activation. This is a deliberate soft-fork choice so + a consensus gap does not stall the chain. + +On the voted path the tracker keys payees by `scriptPubKey`, not by +vin, so `vinOut` is explicitly cleared (`CTxIn()`) — a downstream +`mnodeman.Find(vinOut)` then returns NULL deterministically rather +than matching a stale leftover vin. + +### A.1.11 `CheckBlock` masternode payee verification — rework + +`CheckBlock` contained **two** masternode/devops payment-verification +blocks. Comparison against the v2.0.0.6 source confirmed both are +ancestral upstream code, byte-for-byte unchanged across v2.0.0.6/7/8 — +nothing here is a recent regression. + +**Block A** (the `foundPayee` / `foundPaymentAndPayee` block) was dead +code. Its core test required a single output to carry *both* the +masternode payee script *and* the masternode payment amount — but it +seeded that amount from the last coinstake vout, which is the *devops* +output. Masternode pays 150 XDN, devops 50 XDN, so the test is +unsatisfiable whenever a real enforced payee exists. Across three +releases on mainnet it has never enforced anything. + +**Block B** (the `nProofOfIndexMasternode` / `fBlockHasPayments` +block) is the real verification — type-aware (PoW and PoS), +structure-checked, amounts checked at known indices, with the +masternode-checks-delay grace logic. + +The rework, three parts: + +- **Block A removed.** ~185 lines deleted, replaced by a marker + comment. One cross-dependency fixed: Block B referenced + `fIsInitialDownload`, declared only inside Block A; the + declaration is re-added to Block B's scope. + +- **PoS voted-payee enforcement added.** The PoW path already had + voted-consensus enforcement; the PoS path had no equivalent. PoS + now mirrors PoW exactly: same gate, same `GetEnforcedPayee` call, + same fall-through to the pre-existing weak check when no + enforceable voted payee exists. + +- **`DoS(10) → DoS(100)`.** Block B's final `!fBlockHasPayments` + rejection is raised consistent with every other hard `CheckBlock` + failure. The startup checks-delay grace window is unaffected. + +Touched file: `cblock.cpp`. + +### A.1.12 Equivocation handling + +Two fixes folded into the v2.0.0.8 release after late-cycle observation +on testnet. + +**OnFreshDsee wiring (Issue 1).** The documented Path A auto-clear +mechanism for the equivocator blacklist — "cleared by OnFreshDsee on +the next legitimate dsee or dseep" — was wired only into the +new-MN-add codepath at `cmasternodeman.cpp:1036`. The dsee known-MN +update path and the dseep heartbeat handler never invoked it. Result: +Path A was dead code in steady-state operation. Once a voter was +marked equivocator, the documented automatic recovery never fired. + +Two call sites added: `cmasternodeman.cpp:880` (dsee known-MN path, +after `pmn->UpdateLastSeen()` inside the `acceptable` branch) and +`cmasternodeman.cpp:1130` (dseep handler, after `pmn->UpdateLastSeen()` +in the heartbeat path).

The + second line overwrote the real last-paid time with the current time + on every copy. Second line removed. + +2. **The `newAddr`/`newVin`/`newPubkey` constructor** (used when a + peer's `dsee` arrives and a fresh `CMasternode` is constructed) + never initialised `nLastPaid` at all. The field held uninitialised + stack memory — typically a small repeating value like `17` — until + the MN was actually paid. Added `nLastPaid = GetAdjustedTime()` so + newly-Registered MNs show "now" until first payment, matching the + default constructor's semantics. + +3. **Redundant `main.cpp` `ProcessBlock` writer removed.** A second + `nLastPaid` writer at `main.cpp` `ProcessBlock` (via + `GetEnforcedPayee → Find(vin) → nLastPaid = GetAdjustedTime()`) + wrote wall-clock "now" (not the paying block's time), used an unset + `vin` on the voted path (so it matched the wrong masternode or + none), and ran *after* `CMasternodeMan::OnBlockConnected` had + already set the field correctly — clobbering the right value with + a wrong one every block. `OnBlockConnected` already identifies the + masternode the block *actually* paid (`FindByPayeeAddress` on the + block's outputs) and sets that MN's `nLastPaid` to the connecting + block's `GetBlockTime()`. The redundant writer is removed from both + the LiteMode and non-LiteMode branches; `OnBlockConnected` is now + the single authority. + +### A.2.2 `getblocktemplate` masternode-winner fix + +`rpcmining.cpp:841-857`. The old code called `GetCurrentMasterNode(1)` +which passed no block height, defaulting to height 0 (genesis block +hash) inside `CalculateScore()`. The same masternode won every block +indefinitely. Fix: replaced with `masternodePayments.GetBlockPayee( +pindexPrev->nHeight + 1, mnPayee, mnVin)` — same data source as block +validation. Added `FindOldestNotInVec` fallback for when `vWinning` is +empty (transition period while network upgrades). + +### A.2.3 Cross-version masternode activation + +`cmasternodeman.cpp:901`. `EnableHotColdMasterNode` check was +`protocolVersion == PROTOCOL_VERSION` — a strict equality that broke +as soon as wallet and daemon were on different builds. Changed to +`protocolVersion >= MIN_PEER_PROTO_VERSION`. Any acceptable version +now activates the masternode regardless of minor version differences. + +### A.2.4 `AvailableCoinsMN` — locked outputs included on MN-start path + +`cwallet.{h,cpp}`, `cactivemasternode.cpp:618`. New parameter +`bool fIncludeLockedMN = false` on `AvailableCoinsMN`; the +`IsLockedCoin` filter in the per-output predicate becomes +`(fIncludeLockedMN || !IsLockedCoin(...))`. `SelectCoinsMasternode` +passes `true`. + +**Production bug**: from the introduction of persistent locks (BDB +record type A4 `lockedoutputs`), the `AvailableCoinsMN` lock-filter +incorrectly treated user-locked collaterals (and the wallet's own +auto-locked collaterals from `LockCoin`) as unavailable. Symptom: +re-Register after a restart failed with `"could not allocate vin"` +whenever the collateral had been locked. Fix architecturally aligns +with invariant 1: locks are user data, not MN state. + +### A.2.5 Remote masternode start now auto-locks the collateral + +`cactivemasternode.cpp` inner `Register(CTxIn, CService, ...)` at the +success path before `return true`. The local-MN path (`ManageStatus()`) +has always called `pwalletMain->LockCoin(vin.prevout)` after a +successful Register; the remote-MN outer `Register(...)` did not. +Both paths now protect collateral identically. Required +`#include "thread.h"` for the `LOCK` macro. + +### A.2.6 `StopMasterNode` — collateral lock no longer auto-released + +`cactivemasternode.cpp:237-246`. Previously called +`pwalletMain->UnlockCoin(vin.prevout)`. Removed. + +Architectural invariant: locks are user data, not masternode lifecycle +state. Auto-unlocking on stop silently undid user-set locks (including +persistent locks set via the `lockunspent` RPC or via the new B2 lock +controls described in C.3). The lock on masternode start (in +`ManageStatus`) is retained — that protects the collateral while the +masternode is running, but is no longer rolled back automatically on +stop. + +### A.2.7 Local masternode start — `masternode.conf`-aware collateral selection + +A locally-started masternode (`CActiveMasternode::ManageStatus`) +selected its collateral by calling the no-txhash `GetMasterNodeVin`, +which scans the wallet for every 2,000,000-XDN UTXO and takes the +first one. The remote-start path passes the collateral txid/index from +`masternode.conf`; the local path consulted `masternode.conf` not at +all. + +On a host whose wallet holds the collateral for several masternodes — +the normal cold/collateral wallet that funds all of an operator's +remotes — a local masternode bound to an *arbitrary* collateral, +frequently one belonging to a declared remote masternode. Two daemons +then ran on one collateral identity, each signing votes with its own +key; the network ban-stormed on the resulting `CheckSignature` +failures. + +`masternode.conf` is now used as a **subtraction filter** by a new +method `GetLocalMasternodeVin`. The wallet scan is kept — it gives +autostart and resilience — and is only disambiguated: + +- **Case A** — a `masternode.conf` entry whose private key matches + this daemon's `masternodeprivkey` is this node's own declaration; + its collateral is used exactly. Deterministic. +- **Case B** — no matching entry: every collateral declared in + `masternode.conf` (those belong to remote masternodes) is subtracted + from the scan, and selection runs on the remainder. + +The local masternode start refuses (with a specific, logged reason +surfaced in `masternode status`) when: the subtraction leaves no +candidate (every collateral in the wallet is a declared remote); or +`masternode.conf` exists but will not parse. `masternode.conf` is +re-validated at masternode-start time rather than relying on the +init-time read. + +A single-masternode operator with no `masternode.conf` sees no +behaviour change. + +Touched files: `cactivemasternode.cpp`, `cactivemasternode.h`. + +## A.3 Peer-reliability and ban-storm prevention (Round 4-A) + +A set of fixes to peer-facing masternode message handling, prompted by +a testnet investigation in which nodes were banning each other's whole +subnets and dropping connections. + +### A.3.1 NAT-hairpin address hygiene + +The testnet runs with `upnp=0` / `discover=0` and manual router +port-forwarding. An inbound port-forwarded connection arrives +NAT-hairpinned — the accepted socket's source address is rewritten to +the LAN gateway (e.g. `192.168.1.1`). The version handler admitted a +peer's reported `addrFrom` into `addrman` without a routability check, +so a non-routable, LAN-relative address could enter `addrman` and be +gossiped network-wide. The `addrman.Add` is now gated on +`addrFrom.IsRoutable()` — the codebase's own predicate. The connection +itself is left intact (messages still flow, a local mesh keeps +working); only the address is prevented from propagating as a network +identity. `main.cpp`. + +### A.3.2 `State()` NULL guard + +`ProcessMessage` dereferenced `State(pfrom->GetId())->nLastBlockProcess` +unconditionally; `State()` returns NULL when the node id is not in +`mapNodeState`. The result is now null-checked. `main.cpp`. + +### A.3.3 `dseg` re-ask penalty + +A peer re-requesting the masternode list inside the rate-limit window +was scored `Misbehaving(34)` — a third of a ban — for what is normal +behaviour after a restart or dropped connection. Three such re-asks +reached the ban threshold. The duplicate request is now rate-limited +and ignored with no misbehaviour score. `cmasternodeman.cpp`. + +### A.3.4 `dseg` requester-side retry + +`DsegUpdate` sent one `dseg` and recorded a 3-hour cool-off +unconditionally — so a lost request, or a peer that dropped before +replying, left the node with no masternode list for three hours. +`DsegUpdate` now picks the retry interval by list state: a short +`MASTERNODES_DSEG_RETRY_SECONDS` (3 min) while the list is empty, the +full 3 hours once it is populated. Self-correcting. +`cmasternodeman.cpp`, `masternodeman.h`. + +### A.3.5 `Misbehaving`-surface audit + +Eight `Misbehaving` calls in the masternode handlers were reviewed +against one test: can the *receiver's* own incomplete or stale state — +not the sender's behaviour — trigger it on an honest peer? Two were +found to be receiver-state-relative and fixed: + +- `dsee` `GetInputAge < MASTERNODE_MIN_CONFIRMATIONS` — `GetInputAge` + is relative to the receiving node's chain height, so a node still + syncing false-positives on a valid `dsee`.

PROOF-OF-STAKE / STAKING + +## B.1 Lock-order deadlocks — ABBA chain and resolution + +### B.1.1 First ABBA — original §23 wedge + +The Windows proof-of-stake staking node became unresponsive several +times during the soak — process alive (GUI/RPC responsive), block +processing inert. The initial unsymboled dumps showed no thread on a +critical section, leading to a withdrawn hypothesis of lock-order +deadlock. + +A symboled debug build resolved it: the cause IS an ABBA lock-order +deadlock — between `cs_main` and the vote-tracker lock `cs` — +gdb-confirmed on the symboled binary. The unsymboled dumps simply +could not show it. + +**Resolved.** `GetCanonicalWinner` and `GetVoteInfo` had their lock +scope narrowed so the global acquisition order is one-directional +(`cs_main` → `voteTracker.cs`). Confirmed by a multi-hour armed soak +with no recurrence, and re-confirmed live: the PoS block at testnet +height 1838 minted cleanly through the activation crossing. + +### B.1.2 Second ABBA — readiness-probe site (CW0, scope-corrected) + +The PoS staker on Windows wedged after ~18 hours of soak (2026-05-28). +GUI/RPC remained responsive; block production stopped; peer count +decayed. Symptoms matched the original B.1.1 pattern, but with the +M1Q queue-based path now in place the lock-order had shifted. + +A symboled debug build with gdb captured the deadlock: + +- Thread 10 (msghand): in `ProcessGetData` calling `GetQueueByHash` — + waiting on `voteTracker.cs`, currently holding `cs_main`. +- Thread 18 (`ThreadStakeMiner`): in the §29 readiness-gate probe + holding `voteTracker.cs` and waiting on `cs_main`. + +Classic ABBA across (`cs_main`, `voteTracker.cs`). + +The initial fix (called CW0) added an outer `LOCK(cs_main)` around the +readiness probe BEFORE the inner `voteTracker.cs` — establishing the +canonical order. **First attempt soaked clean for 24 hours and then +wedged again at the 18-hour mark on 2026-05-30**, with a different +gdb signature: cs_main held by the staker thread itself, no contention +with msghand. + +Root cause of the recurrence: the LOCK had been applied at correct +lock order but with too-wide scope — covering a `MilliSleep(5000)` +defer in the readiness-probe path. Under sustained defer (queue +tracker not yet ready), cs_main was held for 5 seconds per loop +iteration, starving cs_main consumers. + +**Resolved.** Scope the LOCK strictly around the +`GetCanonicalWinnerFromQueues` call site; release the lock BEFORE the +`MilliSleep`. +21 lines of code (mostly explanatory comment), one +additional brace pair, zero semantic change beyond scope.

The 18-hour-mark pattern across all three wedges +resolves to the mean-time-to-collision for this ABBA on this fleet +topology. + +A brace-aware audit of every site that takes `voteTracker.cs` +identified **6 Class B** (canonical-order-violating) call sites, all +reaching the inner lock through one of two functions: +`GetCanonicalWinnerFromQueues` or `GetQueueInfo`. + +**Resolved.** Two `LOCK(cs)` → `LOCK2(cs_main, cs)` upgrades: + +- `cmasternodevotetracker.cpp:725` + (`GetCanonicalWinnerFromQueues`): covers `CreateCoinStake` (PROVEN + bug), `getblocktemplate`, masternode-winners RPC, and `CheckBlock` + x2 via submitblock RPC. +- `cmasternodevotetracker.cpp:951` (`GetQueueInfo`): covers + `getvoteinfo` RPC. + +Functions are now self-protecting against any caller that doesn't +already hold cs_main. `boost::recursive_mutex` makes the redundant +re-acquire from already-correct callers (CW0, ProcessMessages, +CreateNewBlock) a no-op. + +**Drift restorations.** Two silent source-tree drifts surfaced during +the CW5 rebuild: + +- `cmasternodevotetracker.h` was missing the `QueueInfo` struct + declaration (21 lines deleted with no commit trail).

The kernel input consumed by a successful PoS +coinstake was previously marked spent only via the catch-all per-block +`FixSpentCoins` reconciliation that ran on a subsequent block +connection. Between coinstake creation and that reconciliation, the +wallet's per-tx `vfSpent` array still showed the kernel input as +unspent. Race scenarios where the staker thread re-examined available +coins in that window could attempt to re-stake the just-consumed UTXO. + +The fix is **a targeted `MarkSpent` call directly in the coinstake +construction path**, immediately after the kernel is successfully +signed. This eliminates the dependency on `FixSpentCoins` running +later — `vfSpent` is in sync with reality from the moment the +coinstake is built. + +Validated on testnet: 16+ stakes, `repairwallet` returns 0 mismatches +after the run (versus the previous behaviour where mismatches +accumulated until reconciliation ran). 30h+ soak clean. No interaction +with watch-only logic (watch-only addresses cannot stake — no private +key — so the targeted MarkSpent operates exclusively on spendable +UTXOs). + +Touched file: `miner.cpp`. + +## B.3 Staker mint-retry storm (Velocity back-off) + +`Velocity()` (`velocity.cpp`) enforces a minimum block spacing +(`BLOCK_SPACING_MIN = 45s`); a too-early PoS block is rejected. But +`ThreadStakeMiner` discarded `CheckStake`'s return value and slept a +flat 500 ms before retrying — so a staker that found a valid kernel +while the chain tip was younger than 45 s rebuilt the same too-early +block, was rejected again, and spun: a tight CPU/log storm until +wall-clock crossed the threshold. + +Fixed in two parts: + +- **Spacing back-off gate.** Before `CreateNewBlock`, the staker + computes `nEarliestValid = tipTime + BLOCK_SPACING_MIN`; if that is + in the future, it sleeps until then (capped per-iteration, + rate-limited log) instead of spinning. A too-early block is never + attempted. + +- **`CheckStake` result honoured.** The loop now captures the bool; + a rejected block backs off the normal miner interval rather than + retrying in 500 ms. + +Touched file: `miner.cpp` (and a `mining.h` include for +`BLOCK_SPACING_MIN`). + +## B.4 Staking icon — state-machine rewrite (CW2 / CW6) + +The interim staking-icon work in the §31 polish pass added a "warming +up" clock for the post-restart window. Subsequent observation showed +the fix was incomplete: + +- It relied on `nLastCoinStakeSearchInterval`, a counter that + `SignBlock` updates only on EXIT-WITHOUT-FINDING-A-BLOCK paths. + On a wallet that finds blocks successfully, the counter stays at + zero — and the icon stayed on "warming up" indefinitely even + while blocks were being produced. +- The tooltip's expected-time-between-blocks calculation used a + difficulty × 2³² formula that conflated network stake weight with + PoW difficulty; produced nonsense values (observed: "1763 days + 13 hours" on a healthy testnet staker). + +### B.4.1 Rewrite (CW2 — supersedes the interim fix) + +A proper state machine replaces the counter-based logic. + +**Miner side** (`miner.cpp`): two `std::atomic` variables published by +`ThreadStakeMiner`: + +- `nLastStakeLoopTime` — `GetTime()` snapshot updated at the top of + every outer-loop iteration. Acts as a heartbeat. +- `fLastStakeLoopProductive` — set to `true` immediately before the + `SignBlock` attempt; set to `false` at every short-circuit branch + (wallet locked, vNodes-empty/IBD, fTryToSync early-out, + voted-consensus defer, velocity-spacing back-off). + +Both atomics are read without lock by the GUI thread. + +**GUI side** (`qt/bitcoingui.{cpp,h}`): a three-state machine +(`Hammer` / `Clock` / `None`) computed by a Phase-A walk (full +prerequisite check) on initial entry; once Hammer is resolved, a +hammer-latch flag transitions to Phase-B walks (invalidating-events +only) plus a 5-minute staleness floor. This eliminates icon flutter on +transient defers — once the staker is running, the hammer holds steady +until something genuinely changes (wallet locks, peers drop, IBD +re-enters, or the staking thread stops responding). + +**Tooltip math** — corrected to the formula the codebase already +exposes via `getstakinginfo`: + +``` +expected_time = GetTargetSpacing × networkWeight / walletWeight + = 120 × networkWeight / walletWeight (seconds) +``` + +Tooltip formats compact: "1d 2h", "3h 4m", "5m 30s", "45s". + +### B.4.2 Maturity-window state (CW6, v1.1 with load-crash fix) + +The CW2 state machine still incorrectly reported `None` / +"not staking" whenever `nWeight == 0`, even on a wallet that was +actively staking — because a frequent-staking wallet with one large +UTXO that recycles rapidly will have all stakeable balance permanently +inside the 25-block maturity window, leaving `GetStakeWeight()` +permanently at 0. + +CW6 adds a fourth path to the icon logic by also checking `GetStake()` +(the immature-coinstake total shown as "Stake" in the Balances panel): + +| Condition | Icon | Tooltip | +|---|---|---| +| `nWeight == 0` AND `nStake > 0` | **Clock** | "Recently staked, coins maturing" | +| `nWeight == 0` AND `nStake == 0` | None | "No mature coins" *(unchanged)* | +| `nWeight > 0` | (existing logic) | (existing) | + +The clock state correctly conveys the in-progress state where coins +are advancing through maturity. + +**v1.1 load-crash correction.** The first version of CW6 caused a +startup crash because it called `GetStake()` before `pwalletMain` was +fully loaded. v1.1 added a `fWalletLoadComplete` guard that defers the +check until the wallet is ready. + +Touched files: `qt/bitcoingui.{cpp,h}`. + +--- + +# C.

Spendable readers still used vfSpent. + +**Observable symptom.** A wallet that observed a transaction +involving its own keys via P2P gossip (rather than initiating it +locally) would leave the consumed inputs flagged as spendable in +vfSpent.

Three independent +demonstrations of the bug pattern: +- Single-input send: reference wallet drifts up by input value; + Fix-C wallet tracks correctly. +- Multi-input send (2000 XDN, 2 inputs aggregated): reference drifts + by change-UTXO value (337.4997); Fix-C tracks correctly; + `repairwallet` on reference reports exact mismatches. +- Staking (7 stakes accumulated): reference drifts by sum of consumed + inputs (249,847.26); Fix-C tracks correctly; `repairwallet` on + reference reports 7 mismatches summing exactly to the drift. + +After Fix C, the only remaining reader of `vfSpent` is `FixSpentCoins` +itself. + +### C.1.3 Watch-only credit — AddToSpends on live-add (v2.0.0.7 work) + +`cwallet.cpp:2625`. `AddToSpends(hash)` was only invoked from the +`fFromLoadWallet=true` branch in `AddToWallet`. Without this in the +live-add branch, `mmTxSpends` was empty for any tx added during a +rescan or live operation. Symptom: watch-only credit on a freshly +imported active address summed to roughly the total ever received +rather than the current unspent balance. Self-healed on restart +because wallet load re-populates `mmTxSpends` from scratch. Note: this +affected watch-only credit only — `GetBalance` did not consult +`mmTxSpends` until CW4 Fix C (C.1.2 above). + +### C.1.4 `nTimeSmart` for rescan-discovered txes + +`cwallet.cpp:2709-2724`. Previously `wtx.nTimeSmart` was clamped UP to +`latestEntry` (the most recent existing tx's time) when a rescan +discovered an older tx. Result: all rescan-discovered txes ended up +timestamped at the most recent existing tx. Now: if +`blocktime < latestEntry`, set `nTimeSmart = blocktime` directly; +otherwise apply the original clamp. + +## C.2 Coin selection + +### C.2.1 `AvailableCoinsForStaking` — per-outpoint locks + +Changed from per-transaction collateral-amount filtering to +per-outpoint locking via `setLockedCoins` (`cwallet.cpp:406-456`). +Previously, an entire transaction was excluded from staking if any +output equalled the masternode collateral amount (2,000,000 XDN) or +any output passed `IsCollateralAmount()` (multiples of 1 XDN between +1 and 5 XDN). This punished: + +- Innocent recipients of 2M XDN payments (entire tx excluded, + including unrelated change outputs) +- Transactions whose change happened to land at a "collateral amount" +- Users who genuinely received 2M but didn't intend to use it as + masternode collateral + +Now: only excludes outputs explicitly locked by the user via Coin +Control, `lockunspent` RPC, or the masternode UI (which writes through +to `setLockedCoins`). + +## C.3 Watch-only + +### C.3.1 P2PK `IsMine` fallback + +`script.cpp:3470-3494`. When a P2PK output's pubkey-derived keyID +isn't in the keystore, construct the P2PKH-equivalent script and +check `setWatchOnly`. If matched, return `ISMINE_WATCH_ONLY`. +Reasoning: `importaddress` stores the P2PKH form of an address in +`setWatchOnly`, but coinstakes and some receives use the P2PK form for +the same logical address. Without this check, those P2PK outputs would +be invisible to watch-only tracking — stake rewards (which are +coinstakes paying back via P2PK) wouldn't be tracked at all. + +Verified dead code for non-watch-only wallets — `keystore.HaveKey(keyID)` +returns true first, returning `ISMINE_SPENDABLE` before ever reaching +this fallback. + +### C.3.2 Spendable stake separation + +`cwallet.cpp:3220` and `cwallet.cpp:3242`. `ISMINE_ALL` → +`ISMINE_SPENDABLE` in the call to `GetCredit` for `GetStake` and +`GetNewMint`. Was counting watch-only stake/mining-reward into the +wallet's own (spendable) stake/newmint columns. Watch-only stake is +now reported separately by `GetWatchOnlyStake()`. + +Verified neutral on non-watch-only wallets — the two filters evaluate +identically when no watch-only addresses are present. + +### C.3.3 `RemoveWatchOnly` — three-phase prune + +Substantially expanded from a one-line wrapper (`cwallet.cpp:1121+`). +Now performs three phases: + +- Phase A (0-60% progress): walk `mapWallet`, identify orphan + transactions whose only relevance to the wallet was via the script + being removed. Outputs of these txes will return `ISMINE_NO` from + `IsMine` after the script is removed, so they would appear as + "(n/a)" ghost rows in the GUI if not pruned. +- Phase B (60-90%): erase orphans from `mapWallet` and from disk via + `EraseTx`. Notify GUI per-erased-tx via + `NotifyTransactionChanged(CT_DELETED)`. +- Phase C (90-100%): mark all remaining transactions dirty so cached + watch-only credit recomputes on next access. + +Now accepts a `RemoveProgressFn` callback for GUI progress reporting +(`cwallet.h:226-227`). Heavy operation on wallets with many +watch-only-related historical txes (the per-tx `IsMine()` evaluation +dominates wall-clock time). + +### C.3.4 Compatibility check against CW4 Fix B + Fix C (new in v2.0.0.8) + +The CW4 Fix B (B.2) writer-side fix and Fix C (C.1.2) reader migration +were audited against the v2.0.0.7 watch-only work and confirmed +non-regressing: + +- **Fix B** operates on the coinstake input within + `CreateCoinStake`/`CreateNewBlock`. The kernel input must be + spendable (no private key, no kernel signature), so Fix B's + targeted MarkSpent operates exclusively on spendable UTXOs. Zero + interaction with watch-only logic. +- **Fix C** migrates spendable readers to `mmTxSpends`. The watch-only + readers (`GetAvailableWatchOnlyCredit`, `GetWatchOnlyBalance`, + `GetWatchOnlyStake`) were already on `mmTxSpends`. Fix C brings + spendable into alignment; both spendable and watch-only readers now + share the same correct spent-tracking semantics. +- All v2.0.0.7 watch-only fixes (P2PK IsMine fallback, RemoveWatchOnly + three-phase prune, GetStake/GetNewMint ISMINE_SPENDABLE filter, + AvailableCoinsForStaking setLockedCoins approach) are preserved + byte-for-byte; none of them are in the Fix B/Fix C edit lists. + +## C.4 Wallet rebuild — `-rebuildwallet` and `Tools → Compact Wallet` + +A complete BDB-cursor-level dump-and-restore mechanism that replaces +`-salvagewallet` for routine wallet maintenance. Reclaims free pages, +rebuilds the B-tree, and produces a smaller wallet file. Preserves +every BDB record type — watch-only addresses, A4 coin locks, stealth +addresses, multisig redeem scripts, the BIP39 mnemonic master key, +address book entries, transaction history, locked outputs, +recovery-phrase flags. Encrypted wallets stay encrypted (the mkey +records are dumped as-is and restored verbatim; no password prompt +during rebuild). + +### C.4.1 Pipeline (`walletrebuild.cpp::RebuildWallet`) + +1. **Pre-flight checks.** Refuse if `wallet.dat.bak`, + `wallet.dat.new`, or `wallet.dat.dump` already exist. Refuse if + free disk space is less than 2× the source wallet size. Refuse if + `wallet.dat` itself is missing. +2. **Dump.** `DumpAllRecords` cursor-walks the source wallet and + writes every record to `wallet.dat.dump` in the v1 dump format. + Read-only on the source. Permissions tightened to 0600 on POSIX. +3. **Close source.** `dbenv.Flush(false)` checkpoints the BDB log and + releases all open handles to the source wallet. +4. **Create from dump.** `CreateFromDump` reads the dumpfile, + validates the double-SHA256 checksum and record count *before* + creating any destination state, then opens a fresh BDB at + `wallet.dat.new` and writes every record. Records are committed + in batches of 10,000 to bound BDB's dirty-page cache. A single + transaction wrapping all records works on small wallets but fails + with `ENOMEM` (BDB ret=12) on large ones — discovered when the + 800k-record dev wallet hit the cache wall at record 172,073. + Periodic commit keeps cache pressure bounded with negligible + commit overhead. +5. **Verify.** `VerifyNewWallet` cursor-walks the freshly written + `wallet.dat.new` and counts records, comparing to the expected + count from the dump footer. Any mismatch aborts the rebuild + without swapping. +6. **Swap.** Two BDB-level renames in order: + `wallet.dat → wallet.dat.bak`, then `wallet.dat.new → wallet.dat`. + Uses `dbenv.dbenv.dbrename()` rather than filesystem `rename()` so + the env's internal log stays consistent with what's on disk. +7. **Cleanup.** Delete `wallet.dat.dump` on both success and failure + — privacy wins over forensic recovery, and the `.bak` is the + rollback path. +8. **Outcome marker.** Write `.rebuildwallet-result` for the GUI to + surface to the user on next paint. + +### C.4.2 Crash recovery + +The handler at the top of `RebuildWallet` detects a state where +`wallet.dat` is missing but both `wallet.dat.bak` and `wallet.dat.new` +are present — the unambiguous signature of a crash between the two +renames in step 6. The recovery is mechanical: complete the second +rename (`wallet.dat.new → wallet.dat`) and write a +`recovered_from_crash` outcome marker. + +### C.4.3 Dump file format v1 + +``` +# DigitalNote wallet rebuild dump created by DigitalNote 2.0.0.8 () +# * Created on +# * Source wallet: +# * Best block at time of dump was (), +# mined on +# * Format: bdb-raw-v1 + + +...

Token values: + `success`, `recovered_from_crash`, `failed_preswap`, + `failed_filesystem`. + +## C.5 `-salvagewallet` deprecation + +The decision to deprecate `-salvagewallet` was made after research into +Bitcoin Core, PIVX, Dash, and Bitcoin ABC. Core removed `-salvagewallet` +in 0.21.0 (PR #17219) for three reasons: default key not preserved, +wallet version not preserved, and keys silently skipped. The DigitalNote +codebase was hitting the third — `CWalletDB::Recover`'s inner loop uses +`DB_NOOVERWRITE`, which silently drops collisions. + +`-salvagewallet` now refuses to run unless `-iknowsalvagewalletisdangerous` +is also passed (`init.cpp:553-589`). The help text points users to +`-rebuildwallet`. The escape hatch is preserved for support cases +where rebuildwallet itself fails on a wallet too corrupt for cursor +iteration. + +## C.6 BIP39 mnemonic recovery (D2 design) + +~675 lines of new functionality in `cwallet.cpp` plus the entire +`src/bip39/` subdirectory. New functions: `AddMnemonicMasterKey`, +`RemoveMnemonicMasterKey`, `HasMnemonicMasterKey`, plus the +modification to `Unlock` that tries all master keys in `mapMasterKeys` +rather than returning false on first decrypt failure. + +The wallet stores two `CMasterKey` envelopes encrypted under different +keys. `CMasterKey[1]` decrypts under the password-derived hex key; +`CMasterKey[2]` decrypts under the recovery-phrase-derived hex key. +Both unlock the same `vMasterKey`. `Unlock` and +`ChangeWalletPassphrase` were both modified to iterate all master keys. + +**Design D2 — recovery phrase derives from `vMasterKey`, not from the +password.** `AddMnemonicMasterKey` takes no arguments; it derives the +mnemonic from the wallet's `vMasterKey` directly. This means the +24-word recovery phrase is **stable across password changes** — once +a wallet has been BIP39-upgraded, the recovery phrase the user wrote +down stays valid even after a `walletpassphrasechange`. +`CMasterKey[2]` is rotated with the new password but the underlying +`vMasterKey` (and therefore the mnemonic) doesn't change. + +GUI: new dialogs `recoveryphraseupgradedialog`, `rotatephrasedialog`, +`seedphrasedialog`. Centralised GUI state management via the new +`guistate` namespace. + +New RPC: `getrecoveryphrase` (in `rpcbip39.cpp`). + +## C.7 Wallet decryption code (NOT CALLED, retained) + +`DecryptWallet` (~200 lines, `cwallet.cpp:1644-1791`). Two-phase +commit: writes all plain keys with overwrite first, then erases +encrypted records, so a mid-operation crash leaves wallet.dat in a +recoverable state. Also writes a safety backup file +(`decrypt_wallet_backup.txt`) before any modification, deleted on +success. + +Marked "NOT CALLED — retained for future use" in source. The Settings +menu shows a "Decrypt Wallet..." label when the wallet is locked, but +the action is permanently disabled (`bitcoingui.cpp:1378-1380`); there +is no live path to invoke `DecryptWallet`.

NETWORK + +## D.1 VRX difficulty-recovery curve — fix and determinisation + +A correctness-and-determinism story across the v2.0.0.6 → v2.0.0.8 +arc. Three distinct items, all in `VRX_ThreadCurve` (`blockparams.cpp`). + +### D.1.1 v2.0.0.6 baseline — the recovery curve never engaged + +In v2.0.0.6, `VRX_ThreadCurve` defined the stall-time input as: + +```cpp +blkTime = pindexLast->GetBlockTime(); +cntTime = BlockVelocityType->GetBlockTime(); +difTime = blkTime - cntTime; +``` + +`BlockVelocityType` comes from +`GetLastBlockIndex(pindexLast, fProofOfStake)` — which walks back to +the most recent block of the *requested* type. On a PoW retarget, +`fProofOfStake=false`, and the walk terminates at `pindexLast` itself +(if `pindexLast` is PoW) or at the most recent PoW ancestor. + +Either way, on the PoW retarget code path, `blkTime == cntTime` and +`difTime == 0`. The recovery loop: + +```cpp +while(difTime > (hourRounds * 60 * 60)) { ... } +``` + +was therefore **dead code in practice** — the predicate was never +true and the loop body never executed. Difficulty did not drop +progressively during stalls; the chain had no automatic recovery +mechanism. Long pauses on mainnet (the "block not found for an hour" +events) had to recover via other means (manual mining catch-up, +network self-correction over many subsequent blocks). This was the +underlying cause of mainnet's painful chain-stall behaviour. + +The bug existed in v2.0.0.6 throughout its lifetime. It is corrected +in v2.0.0.8 by introducing a real `difTime` value (see D.1.2 below) +and then making the calculation deterministic (D.1.3). + +### D.1.2 Curve-engagement fix introduced post-v2.0.0.6 (wall-clock based) + +Between v2.0.0.6 and the v2.0.0.7/v2.0.0.8 development cycle, a fix +was added to make the recovery curve actually engage during stalls: + +```cpp +wallClockDelta = GetAdjustedTime() - blkTime; +difTime = std::max(blkTime - cntTime, wallClockDelta); +``` + +`GetAdjustedTime()` is the node's network-adjusted wall clock. When +the chain stalls, the wall clock advances past the last block time, +`wallClockDelta` grows, the recovery loop engages, and difficulty +drops progressively. This worked correctly at mint time: the miner's +wall clock at block-construction time is approximately the block's +own timestamp, so the computed `nBits` is approximately what the +block ends up sealed with. + +But it broke from-genesis resync. When a node re-validates a +historical block, the validator's `GetAdjustedTime()` is the current +wall clock (potentially years after the block was mined), `blkTime` +is the historical block's predecessor time, `wallClockDelta` is +*enormous*, the recovery loop engages hard, and the validator +computes a completely different `nBits` than the block carried. +Result: `AcceptBlock` rejects the block on the `nBits` mismatch and +the chain cannot resync past the first stall-recovery block. + +This was the manifested symptom that originally motivated D.1.3 — +chains failing to resync past a specific block in the historical +record. + +### D.1.3 Determinism via committed block time + +D.1.3 preserves the engagement behaviour of D.1.2 (the curve does +fire during real stalls) while making the validator's calculation +deterministic. + +Threaded an optional `int64_t nNewBlockTime` through +`GetNextTargetRequired → VRX_Retarget → VRX_ThreadCurve`. Final form: + +```cpp +int64_t blockDelta = blkTime - cntTime; +int64_t nEffectiveNewTime = (nNewBlockTime > 0) ? nNewBlockTime + : GetAdjustedTime(); +int64_t wallClockDelta = nEffectiveNewTime - blkTime; +difTime = std::max(blockDelta, wallClockDelta); +``` + +Caller responsibilities: +- **Validation** (`AcceptBlock` in `cblock.cpp`) passes the candidate + block's committed `GetBlockTime()`. The retarget for a given + historical block is now a pure function of committed chain data + and reproduces identically on every node, forever. +- **Mining** (`miner.cpp:251`, in `CreateNewBlock`) passes + `GetAdjustedTime()` — preserves D.1.2's curve-engagement + behaviour during live block production. +- `nNewBlockTime == 0` is the defensive "not supplied" fallback to + `GetAdjustedTime()` rather than computing a nonsense negative + delta. + +A fresh testnet genesis was rebuilt on a binary containing this fix; +that chain resyncs from genesis with no `nBits` mismatch. + +Touched files: `blockparams.{h,cpp}`, `cblock.cpp`, `miner.cpp`, +`rpcmining.cpp`. + +### D.1.4 Historical mainnet `nBits` exception list — extended + +The mainnet historical `nBits` exception list in `AcceptBlock` falls +into two categorically distinct classes. Both are canonical chain +history; both must be honoured by any conforming validator; but they +have unrelated origins and are documented separately so the +provenance of each entry is clear. + +**Class A — controlled fork operations (4 entries, pre-existing).** +Blocks produced under deliberately-set minimum difficulty +(`1f00ffff`) as part of controlled chain operations: + +- Heights **46921, 46923, 46924** — the v1.0.1.5 mandatory-update + activation cluster, May 2019. Three blocks within ~3 minutes, all + at floor difficulty, all carrying the activation transition for + the mandatory upgrade gated by + `VERION_1_0_1_5_MANDATORY_UPDATE_START`. +- Height **403116** — the predecessor block to the v1.0.4.2 + hardfork at height 403117. Floor difficulty was set to provide a + deterministic, instantly-mineable anchor block immediately + preceding the chain correction. Block 403117 itself carries the + one-shot treasury operation (1,000,000,000 XDN injection via + `GetDevOpsPayment`'s `nHeight == VERION_1_0_4_2_MANDATORY_UPDATE_BLOCK` + branch) and is *not* in the exception list — its `nBits` is + consensus-derivable. + +These four entries have always been in the exception list (since +v2.0.0.6 or earlier). They are not "stall-recovery archaeology" and +v2.0.0.8 does not change their status. Listed here for completeness +of the exception-list provenance record. + +**Class B — stall-recovery archaeology (~30 new entries).** +Blocks where v2.0.0.6's broken VRX recovery curve (D.1.1) produced +different `nBits` than v2.0.0.8's working curve (D.1.2 / D.1.3) +computes. v2.0.0.6's recovery loop never engaged at all (`difTime` +was always zero on PoW retarget), so during long stalls the miner +computed difficulty from the standard NORMAL retarget path while +v2.0.0.8's working curve correctly drops difficulty toward the +floor. Each Class B block is a stall-recovery event somewhere in +mainnet history, identifiable by: + +- A long block-spacing gap from the preceding block (typically + exceeding the recovery curve's hourly boundaries at 3600 / 7200 / + 10800 / 14400 / 18000 seconds) +- A `nBits` mismatch where v2.0.0.8's computed value is *easier* + than what the block carries (mantissa larger, or exponent higher) +- Distribution roughly 75% PoS / 25% PoW, spread across mainnet + history from May 2019 through 2024 with no era concentration +- Two extreme cases (heights 394624 and 423410) where v2.0.0.8's + curve fully reached the `1f00ffff` floor + +These blocks were consensus-valid under v2.0.0.6 rules at mint +time. v2.0.0.8 grandfathers them via height exception so the +working-curve correction does not invalidate existing chain +history. + +A representative illustrative case is **height 138092**, a +December 2019 PoS block sealed after an 82-minute stall. Three +distinct historical mechanisms visible in the same block: + +1. **Pre-swap reward layout**: at this height the staker reward was + 150 XDN and the masternode reward was 100 XDN (see H.6 for the + reward swap at height 403117). The staker received their 150; + the masternode would have received 100. +2. **Devops fallback fired**: the 82-minute stall left the producer + with a stale local masternode list, so `GetCurrentMasterNode()` + returned no payee, and the masternode share was paid to the + devops address per the consensus fallback rule. Devops received + 100 (the unclaimed MN share) plus 50 (the normal devops payment), + summing to 150 XDN to devops in that block. Total subsidy + remained `nBlockStandardReward` (300 XDN) — staker 150 + devops + 150. +3. **Broken VRX curve**: block carries `1c096cbb` (v2.0.0.6 NORMAL + retarget value), v2.0.0.8 computes `1c12d977` (easier — the + working curve dropped difficulty for the long stall). + +Each of these is canonical and intentional under the rules at the +time. v2.0.0.8 does not change any of them; the exception list +makes block 138092 acceptable to a re-syncing v2.0.0.8 validator +without disturbing its historical content. + +**Architectural property preserved.** The strict `nBits` check +remains fully active. There is no tolerance band, no leniency, no +relaxed comparison. The exception list is a height-keyed allow-list +that the validator consults before applying the strict check — +forgery at any non-exception height fails immediately, and forgery +at an exception height would require winning the chain-work race +for that historical block (computationally infeasible). + +**Exception list closure**. Every block mined under v2.0.0.8 +produces `nBits` from the deterministic working curve, so miner and +validator necessarily agree (see D.1.5 for the residual edge case +and its CW7 fix that eliminates it entirely). The exception list +**never grows after v2.0.0.8 tag** — Class A is by definition +historical, and Class B is closed by D.1.3+D.1.5 working together +for all post-tag blocks. + +Touched file: `cblock.cpp` (exception list constants and the height +check at the `nBits != nBitsRequired` site). + +### D.1.5 Mining-side same-timestamp guarantee (CW7) + +The post-D.1.3 mining code at `miner.cpp:251` calls +`GetNextTargetRequired(..., GetAdjustedTime())` early in +`CreateNewBlock`, before `pblock->nTime` is finalized (at +`miner.cpp:701`, with `UpdateTime` applied for PoW at line 705). The +two wall-clock reads are typically within milliseconds-to-seconds of +each other and round to the same answer through the recovery loop's +hourly boundaries. + +But for a stall block whose wall-clock delta from `blkTime` is +straddling one of the recovery-loop boundaries (3600, 7200, 10800, +14400, 18000 seconds), the few-second gap between the two reads can +push the validator-recomputed delta across the boundary, producing a +different `nBits`. The block then fails its own producer's +self-validation in `AcceptBlock` and is silently dropped; the miner +restarts `CreateNewBlock` with a fresh timestamp and usually +succeeds on retry, but in rare cases the block proceeds and becomes +a new historical mismatch requiring an exception-list entry. + +Probability per stall: approximately `(typical T_seal - T_nbits +gap) / (boundary spacing) × (boundaries reached)` ≈ `5s / 3600s × 5` +≈ 0.7%. + +**Fix**: compute `pblock->nBits` from the *same* timestamp that will +be sealed into `pblock->nTime`. `pblock->nBits` is set at line 251 +but never read between lines 251 and 701, so the assignment can be +moved to after `pblock->nTime` is set: + +```cpp +// In CreateNewBlock, after pblock->nTime is finalized (around line 705 +// for PoW, line 701 for PoS): +pblock->nBits = GetNextTargetRequired(pindexPrev, fProofOfStake, pblock->nTime); +``` + +After CW7, miner and validator compute `nBits` from the byte-identical +`pblock->nTime` value. There is no possible boundary-crossing +divergence; no new historical exception entries can arise from +post-tag blocks; the D.1.4 exception list is permanently closed at +its v2.0.0.8 size. + +Touched file: `miner.cpp` — one line moved, one line deleted. + +### D.1.6 Diagnostic logging + +`VRX_Retarget DIAG` lines — per-block retarget path +(`DRYRUN` / `CRVRESET` / `NORMAL`) with `difTime`, `hourRounds`, and +the computed `nBits`. `AcceptBlock nBits MISMATCH` line — prints, on +any difficulty mismatch, the `nBits` the block carries versus the +`nBits` the node computed. Both are gated behind `-debug=retarget` +in normal operation; the `MISMATCH` line is left ungated as a +reject-path diagnostic that is operationally valuable. + +Post-CW8 the `MISMATCH` line additionally carries a `[PoS]` / `[PoW]` +tag so future archaeology doesn't need a separate enrichment pass. + +## D.1bis Devops address rotation, strict-check re-enablement, and producer/validator off-by-one fix (CW9) + +A coordinated three-part change shipped under the umbrella label +"CW9" and gated by the consensus constant +`VERION_2_0_1_0_MANDATORY_UPDATE_BLOCK = 1400000` on mainnet and +`VERION_2_0_1_0_TESTNET_UPDATE_BLOCK = 100` on testnet. Together +these resolve the longstanding deferral of "Dev address rotation" +recorded in earlier changelogs as H.8, fix a producer/validator +off-by-one in the ladder lookup that has been latent since v1.0.1.5, +and restore the strict devops-address check that was commented out +sometime in the v2.0.0.6-or-earlier era. + +### D.1bis.1 The deferred problem + +The v1.0.4.2 devops address `dafC1LknpDu7eALTf5DPcnPq2dwq7f9YPE` has +been the active devops recipient since July 2021. Over the +intervening four-plus years its wallet has accumulated hundreds of +thousands of incoming transactions (one per block, plus reward +splits, plus user donations, plus internal operational +transactions). Repeated Compact Wallet runs reduce the live record +set but cannot reduce the BDB file below approximately 720MB — +appended-only growth and free-list fragmentation keep the on-disk +footprint large even after compaction. + +A wallet that large is operationally painful (slow rescans, long +backup times, slow `repairwallet`, slow `dumpwallet`) and creates a +single point of failure: the entire treasury's spending capability +depends on one wallet file that has been continuously operating +across multiple Linux distributions, multiple Bitcoin-Qt forks, and +multiple binary upgrades. The rotation moves the active receiving +address to a fresh wallet with no transaction history, immediately +restoring fast operations. + +### D.1bis.2 Rotation activation parameters + +| Network | New devops address | Activation block | Activation date (estimated) | +|---|---|---|---| +| Mainnet | `dGoFPie9QZmQ1Ty1beqSHytxNruehpGtGa` | 1,400,000 | ~early September 2027 (at current ~164,981 blocks/year, ~15 months from June 2026 tip 1,180,777) | +| Testnet | `tSRDftd9ghEZq3pbwRmwp2FT7VuLcvmtnX` | 100 | Within first few hours of testnet genesis-restart | + +Both addresses are fresh wallets generated specifically for v2.0.1.0. +No prior transaction history; not derivable from any pre-rotation +wallet. The testnet activation height of 100 is intentionally early +so that the rotation mechanism is exercised live within the first +hour of testnet operation, providing immediate empirical +confirmation that producer and validator agree on the rotation +boundary before the same code reaches mainnet. + +### D.1bis.3 The off-by-one — diagnosis + +`getDevelopersAdress(const CBlockIndex*)` returned the devops address +expected for the block referenced by its `pindex` argument. Code +called this with two distinct meanings: + +**Validator** (`cblock.cpp:1322`): passed `pindex` — the block being +validated. Correct: asks "what address should THIS block pay?" + +**Producer** (`miner.cpp:531`, `miner.cpp:617`, `cwallet.cpp:4046`, +`cwallet.cpp:4126`, `rpcmining.cpp:830`): passed `pindexBest` or +`pindexPrev` — the chain tip, NOT the block being constructed. +Incorrect: asks "what address did the PREVIOUS block pay?" when the +intent was "what address should the block I'm about to mine pay?" + +At any rotation boundary, ladder(N-1) ≠ ladder(N), so the producer +constructed a block paying the OLD address while the validator +expected the NEW. The defect was latent across the entire chain +history because: + +- v1.0.0.0 → v1.0.1.5 transition (May 2019): occurred during a + controlled hardfork with time-based gates and a transition window + where validator was lax +- v1.0.1.5 → v1.0.4.2 transition (July 2021): occurred during a + controlled chain-correction rollback (block 403116 → 403117) where + the validator was forced lax by checkpoint +- The strict address check had been commented out since pre-v2.0.0.6, + so post-rotation chain mismatches logged but did not reject + +Without the strict check, the only observable consequence was that +producers paid the OLD devops address for one block at each rotation +boundary. Audit of mainnet chain history confirms: block 65020 +(v1.0.1.5 rotation) and block 403117 (v1.0.4.2 rotation) both have +producer-paid recipients that disagree with the ladder's expected +output. Both blocks remain canonical mainnet history. + +### D.1bis.4 The off-by-one — fix + +The ladder function is refactored to take height directly. The +existing `CBlockIndex*`-based signature becomes a thin wrapper. + +```cpp +// New primary function. Caller passes the height of the block +// whose devops payee is being determined. +std::string getDevelopersAdressForHeight(int nHeight, int64_t nBlockTime); + +// Backward-compatible wrapper, used by validator code. +std::string getDevelopersAdress(const CBlockIndex* pindex); +``` + +The wrapper delegates: `return getDevelopersAdressForHeight(pindex->nHeight, pindex->GetBlockTime());` + +All producer callers migrate to the height-based form, passing +`pindexBest->nHeight + 1` or `pindexPrev->nHeight + 1` (the height +of the block being constructed): + +```cpp +// Before (off-by-one): +getDevelopersAdress(pindexBest); + +// After (correct): +getDevelopersAdressForHeight(pindexBest->nHeight + 1, GetAdjustedTime()); +``` + +Validator callers continue using the wrapper — their `pindex` +argument was already the block being validated, so no off-by-one +exists on that side. Wrapper preserves source-level compatibility +without changing semantics. + +The `nBlockTime` parameter on the new function is used only by the +legacy pre-v1.0.1.5 time-based boundary check (`nBlockTime < +VERION_1_0_1_5_MANDATORY_UPDATE_START`). Any timestamp from a block +mined post-May-2019 produces the same result through that branch, +so producers calling the new function from the present forward may +pass `GetAdjustedTime()` interchangeably with any committed block +time. + +### D.1bis.5 Strict check re-enablement — height-gated + +The commented-out blocks at `cblock.cpp:1530-1536` (PoS path) and +`cblock.cpp:1715-1721` (PoW path) are restored, with a height gate +ensuring the strict comparison fires only from the rotation +activation block onwards: + +```cpp +// New (post-CW9): +LogPrintf("CheckBlock() : PoS Recipient devops address validity " + "could not be verified -- expected %s, got %s\n", + strVfyDevopsAddress.c_str(), + addressOut.ToString().c_str()); + +const int nStrictHeight = TestNet() + ?

Block at exactly height 403117 returns the + v1.0.1.5 address according to the ladder, even though chain history + shows that block actually paid the v1.0.4.2 address. The lax + pre-rotation validator absorbs this; do not change `<=` to `<` + because chain history depends on the existing comparison semantics + at the validator side (the strict check having been commented out + is exactly what allowed this discrepancy to persist). + +- **New v2.0.1.0 boundary uses `<` (strictly less than)**. Block at + exactly `VERION_2_0_1_0_MANDATORY_UPDATE_BLOCK` returns the NEW + v2.0.1.0 address — i.e. the rotation activation block itself is + the FIRST block under the new regime. Producer and validator + agree because both ask the ladder about the same height after the + off-by-one fix. + +### D.1bis.7 Why no transition window + +The v1.0.1.5 rotation included a transition window: a 52-hour period +(`VERION_1_0_1_5_MANDATORY_UPDATE_START` to +`VERION_1_0_1_5_MANDATORY_UPDATE_END`) during which the validator +accepted either the old or new address. The intent was operator +forgiveness during the upgrade window. + +Empirically that transition window caused more problems than it +solved. The v1.0.1.7 historical commit +(`911ec6fbaa72839b4309e35e5e45caa8d855df04`) reveals that the +transition-window code had an off-by-one: it used +`pindexBest->GetBlockTime()` (the chain tip's timestamp) instead of +`pindex->GetBlockTime()` (the block being validated's timestamp). +After the tip's timestamp passed `_END`, strict mode kicked in +retroactively for ALL blocks during resync — including those within +the transition window — breaking from-genesis sync. The fix in the +v2.0.0.x era was simply to comment out the strict check entirely. + +CW9 ships without a transition window. The producer/validator +off-by-one fix removes the original reason transition windows were +needed (producer and validator now agree on every block including +the boundary). Removing the window also removes the entire class of +off-by-one bugs that haunted the v1.0.1.5 transition. + +### D.1bis.8 Pre-rotation chain history is canonical and unchanged + +CW9 changes nothing about the validation of any block at height < +`VERION_2_0_1_0_MANDATORY_UPDATE_BLOCK`. The lax pre-rotation +validator continues to accept whatever the chain history shows. +This is the correct design choice: any attempt to retroactively +re-validate the chain under stricter rules would reject blocks +that have been canonical for years, breaking resync for every +operator at every level (full nodes, exchanges, pool operators, +explorer maintainers). + +The full pre-rotation chronology of devops payments, established +through full-chain archaeology against v2.0.0.6 source and confirmed +empirically via RPC probe (June 2026): + +| Phase | Heights | Time | Devops behaviour | +|---|---|---|---| +| Reserve emission | 1 → ~16 | Jan 27 2019+ | Bulk 80M XDN supply; no devops vouts | +| Standard rewards, no devops | ~16 → 28265 | Jan-Apr 2019 | Pre-`START_DEVOPS_PAYMENTS` | +| **Devops + MN activation** | 28266 | **Apr 5 2019 20:00 UTC** | `START_DEVOPS_PAYMENTS = 1554494400` gate fires | +| v1.0.0.0 era | 28266 → 65019 | Apr-Jul 2019 | `dSCXLHTZ...` is devops recipient (sparse early — masternodes paid the share on some blocks; consistent later) | +| **v1.0.1.5 rotation** | 65020 | **Jul 2 2019 21:05 UTC** | Single-block rotation to `dHy3LZv...` (same UTC second as 65019 — single producer's binary swap-over) | +| v1.0.1.5 era | 65020 → 403116 | Jul 2019 → Jul 2021 | `dHy3LZv...` is devops recipient | +| **v1.0.4.2 rotation** | 403116 → 403117 | **Jul 2021** | Chain-correction hardfork; 1B XDN treasury injection at 403117; rotation to `dafC1Lkn...` | +| v1.0.4.2 era | 403117 → 1,399,999 | Jul 2021 → ~Sep 2027 | `dafC1Lkn...` is devops recipient | +| **v2.0.1.0 rotation** | 1,400,000 | **~Sep 2027** (estimated) | Rotation to `dGoFPie9...`, strict check re-engages | +| v2.0.1.0 era | 1,400,000 → ∞ | ~Sep 2027+ | `dGoFPie9...` is devops recipient | + +One peculiarity of the v1.0.0.0 era is worth recording: the address +`dSCXLHTZJJqTej8ZRszZxbLrS6dDGVJhw7` was an active PoS staking +wallet (84 staking-reward blocks observed between heights 2300 and +18400) before it was anointed as the v1.0.0.0 devops recipient at +block 28266. Whoever was running that staker also became the +devops operator. The two roles continued in parallel — same wallet, +collecting both staking rewards as a normal PoS participant AND +50-XDN devops payments as the consensus-defined recipient — until +the v1.0.1.5 rotation moved the devops role to `dHy3LZv...`. + +Blocks 28331 and 28332 have anomalous coinstake-position amounts +(50.50 and 50.0002 instead of exactly 50). These are early coinstake +construction bugs in the v1.0.0.0 binary that included fee components +in the devops vout amount. Fixed in some subsequent point release; +the affected blocks are canonical history and validate lax under +CW9. + +### D.1bis.9 Producer/validator agreement under the new design + +After CW9, the canonical producer-validator agreement at the +rotation boundary is: + +``` +Block 1,399,999 (mainnet, the LAST block of the v1.0.4.2 era): + Producer asks getDevelopersAdressForHeight(1399999, t) + -> nHeight < VERION_2_0_1_0_MANDATORY_UPDATE_BLOCK (1400000) + -> returns VERION_1_0_4_2_DEVELOPER_ADDRESS = "dafC1Lkn..." + Validator asks getDevelopersAdressForHeight(1399999, t) (via wrapper) + -> same result, "dafC1Lkn..." + Strict check: nHeight (1399999) >= nStrictHeight (1400000) is false + -> lax check, accept regardless + +Block 1,400,000 (mainnet, the FIRST block of the v2.0.1.0 era): + Producer asks getDevelopersAdressForHeight(1400000, t) + -> nHeight < VERION_2_0_1_0_MANDATORY_UPDATE_BLOCK is FALSE + -> returns VERION_2_0_1_0_DEVELOPER_ADDRESS = "dGoFPie9..." + Validator asks getDevelopersAdressForHeight(1400000, t) + -> same result, "dGoFPie9..." + Strict check: nHeight (1400000) >= nStrictHeight (1400000) is true + -> STRICT enforcement engaged + Producer paid "dGoFPie9..."

This anchors the chain past the rotation +window, preventing deep reorgs from reaching back into the lax +pre-rotation validation region. + +Until that checkpoint ships, deep-reorg protection in the rotation +window relies on accumulated chain work alone. Adequate at +>2000 confirmations under normal operation, but explicit +checkpointing is the canonical mechanism and should be added when +the block exists. + +## D.1ter GUI transaction-list one-block lag for locally-mined PoW coinbases (CW10) + +### D.1ter.1 The symptom + +Solo PoW miners on v2.0.0.8 reported that newly-mined coinbase +rewards did not appear in the wallet GUI's *Recent Transactions* or +*Transactions* tab when the block was sealed.

When the GUI thread processes it, +`priv->updateWallet` examines the captured `showTransaction=false` +for `CT_NEW` and silently drops the row. + +The chain link is then completed at `cblock.cpp:2283`: + +```cpp +pindexNew->pprev->pnext = pindexNew; +``` + +But the GUI's queued-event was already dispatched with the +pre-link `showTransaction=false` value. + +### D.1ter.3 The historical "previous-block" hack + +The original Bitcoin-Qt code base addressed this with a deferred +notify in `cblock.cpp:1103-1110`: + +```cpp +if (pindexNew == pindexBest) +{ + // Notify UI to display prev block's coinbase if it was ours + static uint256 hashPrevBestCoinBase; + + g_signals.UpdatedTransaction(hashPrevBestCoinBase); + hashPrevBestCoinBase = vtx[0].GetHash(); +} +``` + +The intent: store the current block's coinbase hash in a static +variable, fire the notify only on the *next* successful chain +extension. By that point the previous block's `IsInMainChain()` is +definitely true, the static handler computes `showTransaction=true`, +and the GUI inserts the row. + +This works — but it bakes in a one-block UI lag for every locally +mined PoW coinbase, forever. PoS coinstakes are not affected +because `vtx[1]` (coinstake) is not subject to the `IsCoinBase()` +filter in `showTransaction()`. Mainnet stakers see their rewards +instantly. Solo PoW miners see them one block late. + +The lag has been present in the code base since the original +Bitcoin Core heritage and survives in many forks. The reason it +came to attention during v2.0.0.8 verification was the genesis- +restart testnet with a single PoW miner — the lag was the only +update path actually exercised under controlled conditions. + +### D.1ter.4 The fix + +`cblock.cpp:1108`. Add one signal emission at the existing +`hashPrevBestCoinBase` site: + +```cpp +if (pindexNew == pindexBest) +{ + static uint256 hashPrevBestCoinBase; + + g_signals.UpdatedTransaction(hashPrevBestCoinBase); + + // v2.0.0.8 CW10: also notify UI of the CURRENT block's coinbase. + // By the time execution reaches here, pnext and pindexBest are + // set correctly, so the re-notify reads IsInMainChain()=true, + // computes showTransaction=true, and the GUI inserts the row. + g_signals.UpdatedTransaction(vtx[0].GetHash()); + + hashPrevBestCoinBase = vtx[0].GetHash(); +} +``` + +`CWallet::UpdatedTransaction()` (cwallet.cpp:6065-6082) guards by +`mapWallet.find(hashTx)` — so the call is a no-op on any node that +didn't mine the block. Nodes that did mine see the GUI update +immediately. + +The pre-existing `UpdatedTransaction(hashPrevBestCoinBase)` line is +preserved deliberately. Should anything elsewhere in the code base +depend on the "previous block coinbase notification" side effect, +that path is unchanged. The new line is purely additive. + +### D.1ter.5 Scope and risk + +| Item | Detail | +|---|---| +| Files touched | 1 (`cblock.cpp`) | +| Net line change | +1 line of code, +30 lines of comment explaining why | +| Header changes | None | +| Consensus impact | None — `g_signals.UpdatedTransaction` is a UI signal only | +| P2P impact | None | +| Wallet.dat impact | None | +| Affects | Solo PoW miners running the GUI | +| Does NOT affect | PoS stakers, pool miners (external), daemon-only nodes, relay nodes | +| Risk | Very low — additive UI signal, existing notify preserved | + +### D.1ter.6 What this validates + +The fix being trivially small (1 effective line) underscores that +this was a pre-existing latent display issue, not a regression +caused by any v2.0.0.7 or v2.0.0.8 work.

The deferred fixes address a hypothetical post-activation propagation race that has not been empirically observed in any test run; they remain ready to ship as a hotfix if the race manifests at activation. + +### D.1quater.1 The symptom + +During v2.0.0.8 testnet validation, a new staker was brought online. +Within minutes a single block (height 206) paying the new staker's +masternode was rejected by **5 of 8** testnet nodes with: + +``` +CheckBlock() : PoW Recipient masternode address validity could not be verified -- rejecting +CheckBlock() : PoW/PoS non-miner reward payments could not be verified +ERROR: CheckBlock() : PoW/PoS invalid payments in current block +Misbehaving: 192.168.1.1:61374 (0 -> 100) BAN THRESHOLD EXCEEDED +``` + +The rejecting nodes had not yet received the new masternode's +`dseep` registration broadcast. The other 3 nodes had received it. +A peer relaying the block was instant-banned (DoS 100, the v2.0.0.8 +penalty for this check, raised from DoS 10 earlier in v2.0.0.8). +Because all peers in the LAN were connecting via NAT hairpin, the +peer-IP `192.168.1.1` represented the gateway interface for every +LAN peer -- effectively partitioning the LAN. Each affected node +sat stalled for the duration of the 24h default ban or until a +non-banned peer happened to deliver the missing broadcast. + +### D.1quater.2 Root-cause structural analysis + +Two layers compound here, both worth unpacking. + +**Layer 1 — Regression: a never-active legacy gate was removed without +understanding why it existed.** + +In v2.0.0.6, the strict "is the payee a registered masternode" check +in `CheckBlock` was wrapped in a flag called `fMnAdvRelay`: + +```cpp +// v2.0.0.6: init.cpp +fMnAdvRelay = GetBoolArg("-mnadvrelay", false); + +// v2.0.0.6: cblock.cpp PoS unknown-payee site +if (nMasterNodeChecksEngageTime != 0) +{ + if (fMnAdvRelay) + { + // reject + fBlockHasPayments = false; + } + else + { + LogPrintf("CheckBlock() : PoS Recipient masternode address + validity skipping, Checks delay still active!\n"); + // do NOT reject -- log only + } +} +``` + +The `fMnAdvRelay` flag defaulted to false and was set only by the +`-mnadvrelay` command-line / config switch, which **was never used in +production** -- no docs, no operator guidance, no examples in the +field point to a node having ever set this true on mainnet. The +effective v2.0.0.6 mainnet behaviour was: this strict check never +fired. Whoever wrote v2.0.0.6 left it disabled-by-default, +presumably aware that it depends on volatile gossip state and +shouldn't be enforced unconditionally. + +In v2.0.0.8, under "Spec C D2: fMnAdvRelay gate removed," we +unconditionally enabled the strict check on the assumption that +"a payee that is neither a registered masternode nor the devops +fallback address is invalid -- reject unconditionally once the +checks-delay warmup has elapsed." That assertion is wrong -- +"invalid" depends on this node's view of the mn list, not on chain +consensus. We removed a protection without understanding what it +was protecting against. + +**Layer 2 — Propagation race that the original gate was protecting +against.** + +Block-propagation outpaces broadcast-propagation. Two independent +gossip pipelines exist for masternode-related data: + +1. **Block relay** -- inv-driven, high priority, deduplicated. A new + block reaches the network in seconds. +2. **Masternode registration relay** -- `dseep`/`dsee`/`mnb`-driven, + lower priority, gossipped to a random subset of connected peers + per relay hop. A new masternode's registration reaches the + network in waves, typically tens of seconds to minutes. + +When a new mn is registered and immediately wins its first payment +(quite common because consensus-selection draws from the eligible +set on every block), the block paying it can systematically arrive +at distant peers before the registration that would validate it. + +This is the same propagation-race that motivated the original +INV/getheaders/getblocks staggering in Bitcoin. v2.0.0.8 did not +inherit a corresponding stagger for the masternode gossip, and the +strict payee check raised the consequence from "drop the block" to +"ban the peer." + +**Combined effect.** Without the v2.0.0.6 fMnAdvRelay gate AND +without any propagation-race mitigation, the strict check fires at +every honest peer that's one gossip hop behind on mn-list state. +On a small testnet cluster with NAT hairpinning, this amplified +into a network-partition-class outage (5 of 8 nodes mutually-banned +the LAN gateway IP for ~1 hour). + +### D.1quater.3 The fix shipping in v2.0.0.8 — CW12 activation gate + +A single targeted change: the strict weak mn-list check in +`CheckBlock` is gated on the voted-consensus activation height. + +At both weak-check sites (PoS ~line 1448 and PoW ~line 1657 in the +v2.0.0.8 tree), the existing `if (nMasterNodeChecksEngageTime != 0)` +guard is widened to include the activation-height check: + +```cpp +const int nWeakCheckActivationHeight = + GetEffectiveVotedConsensusActivationHeight(); + +if (nMasterNodeChecksEngageTime != 0 && + pindex->nHeight >= nWeakCheckActivationHeight) +{ + LogPrintf("CheckBlock() : PoS Recipient masternode address " + "validity could not be verified -- rejecting\n"); + fBlockHasPayments = false; +} +``` + +`GetEffectiveVotedConsensusActivationHeight()` is the canonical +"are we post-activation?" check used elsewhere in v2.0.0.8 by +`GetEnforcedPayee` (the strong voted-consensus check, which is +correctly self-gated already).

Post-voted-consensus-activation, the weak check is +essentially a redundant fast-path; pre-activation, it asks a +question whose answer doesn't constrain consensus. + +Gating CW12 on `GetEffectiveVotedConsensusActivationHeight()` +therefore: + +- Aligns the weak check's activation with the feature it logically + belongs to (voted-consensus enforcement) +- Respects the SPORK_15 spork override (same trigger for both gates) +- Restores v2.0.0.6 effective mainnet behaviour pre-spork (since + the mainnet floor defaults to INT_MAX, the check never fires + without an operator-set spork) +- Engages strict enforcement at exactly the height voted-consensus + becomes the canonical mn-payment selector + +### D.1quater.5 Scope and risk + +| Item | Detail | +|---|---| +| Files touched | 1 (`cblock.cpp`) | +| Net code change | ~12 lines effective (2 sites × `const int` decl + widened `if` predicate), plus ~50 lines of inline comments explaining the history and rationale | +| New variable | 1 local `const int nWeakCheckActivationHeight` per site | +| New function | None | +| New include | None | +| Header changes | None | +| Consensus impact | **None for the SAME network state.** CW12 restores v2.0.0.6-effective behaviour pre-spork; post-spork it engages the strict check at the same height voted-consensus enforcement engages anyway (so the union of validation rules is unchanged).

CW11 + PB-MN-FETCH Lite remain coded, verified, +packaged in `v208-CW11-PBMNFETCH-DEFERRED-bundle.zip`, and ready +to ship as a hotfix if the race manifests at mainnet activation +or in extended post-activation testnet soak. Full description in +`DEFERRED-CW11-PBMNFETCH-notes.md`. + +### D.1quater.7 What this validates + +CW12 closes the observed bug on the testnet (block 206 ban +storm) by restoring v2.0.0.6 effective behaviour pre-spork. It +also makes explicit what Spec C D2 already intended ("strict +check engages under identical conditions" to voted-consensus +enforcement) -- the implementation missed the explicit +activation-height check at the weak site, assuming the upstream +warmup gate was sufficient. CW12 corrects that oversight. + +For mainnet, this means: + +- v2.0.0.8 nodes running with default config (no + `SPORK_15_VOTED_CONSENSUS_ACTIVATION` override) behave + identically to v2.0.0.6 mainnet for masternode-payee + enforcement. No new rejections, no new bans. +- A future mainnet `SPORK_15` to enable voted-consensus + enforcement activates BOTH the weak and strong checks at the + same height, in lockstep. This is the design intent. + +For testnet, this means: + +- The current testnet (~height 214, floor 2000) will not fire + the weak check until height 2000. The block 206 scenario will + not recur at current heights. +- When the testnet reaches 2000 (or a future SPORK_15 lowers + the floor), strict enforcement activates cleanly. At that + point, observe whether the deferred propagation-race scenario + manifests -- if it does, deploy `v208-CW11-PBMNFETCH-DEFERRED-bundle.zip`. + +## D.1quinquies Debug logging operator-experience fix (CW14) + +### D.1quinquies.1 The trap + +The `-debug=` flag in v2.0.0.6 / pre-CW14 v2.0.0.8 +supported 21 categories (listed in `--help` output).

No `LogPrint("1", ...)` calls + exist, so the daemon ran with `fDebug=true` but no extra log + output appeared. +- `-debug=all` — same trap, more egregious because the operator + explicitly asked for "all categories." + +This was discovered during 2026-06-08 stress-test prep when an +operator using `-debug=1` couldn't see expected `checkblock` +category output, then asked why.

This worked +pre-activation but was wrong: `pindex->pnext == NULL` is true for +BOTH a live new tip (must run the payee check) AND the stored tip +during the verify pass (must skip) — one bit cannot separate them, so +the tip's check ran against an empty masternode list and rejected. +Discovered post-activation on two nodes. + +**Resolved fix:** restored the genuine 2.0.0.6 / 2.0.0.7 guard +`hashPrevBlock == hashBestChain` ("this block extends the current +tip"), which DOES separate the two states (live new block extends the +still-current tip → runs; no stored block, not even the tip, extends +it during verify → skips). Two expression-only edits (PoS + PoW); the +enforcement block is nested inside the same guard so both the weak +check and the voted-consensus enforcement get the corrected behaviour. + +Reorg connects also skip (fall through to legacy — safe; those blocks +were strict-checked on first receipt). + +Accepted, documented behaviour: enforcement has a defined blind window +during initial block download and post-stall recovery (tip more than +8h old). This is correct soft-fork behaviour — enforcement is a +current-tip activity. + +## D.3 Velocity miner timing (already covered in B.3) + +Cross-reference: B.3 covers the staker mint-retry storm caused by +`Velocity()`'s 45-second minimum block spacing being applied without +back-off.

TESTNET + +## E.1 Testnet — established and operational + +**New in v2.0.0.8.** A working testnet is a deliverable of this cycle +in its own right. The release's central feature (voted consensus, +A.1) genuinely cannot be validated without a live multi-node network, +and bringing that network up was substantial work — not a footnote to +the code changes. + +### E.1.1 Why a clean rebuild was necessary + +An initial testnet attempt became unrecoverable during development. +It had been run across several iterations of buggy pre-fix binaries +and accumulated: a forked PoS staker, mutually-banned nodes, and — +critically — chain history that could not be resynced past a stalled +block because of the VRX non-determinism bug (D.1.3). It was no longer a +sound substrate for testing consensus. + +Rather than nurse a corrupted chain, the testnet was rebuilt from +genesis on a binary containing the D.1.3 VRX fix plus the +voted-consensus work. This is a *genesis-clean restart*, not a new +genesis: the testnet genesis block is hardcoded in +`ctestnetparams.cpp` and unchanged (`nTime` 1547848830, `nNonce` +16793, hash +`0x000510a669c8d36db04317fa98f7bf183d18c96cef5a4a94a6784a2c47f92e6c`, +asserted at startup). Every node's chain data was wiped; the daemon +re-creates block 0 from the hardcoded definition and the chain is +mined fresh from block 1 by the fixed binary. + +### E.1.2 Testnet parameters + +From `ctestnetparams.cpp` and related headers: + +- P2P port `28092`, RPC port `28094`. +- Network selected with the `-testnet` switch only. +- Genesis: 18 Jan 2019 (`timeTestNetGenesis`), coinbase output is + empty (`SetEmpty()`) — there is **no premine baked into the + testnet genesis**; a fresh testnet is funded entirely by mining + from block 1. +- Masternode payments and devops payments are active from block 1 + (`START_MASTERNODE_PAYMENTS_TESTNET` / + `START_DEVOPS_PAYMENTS_TESTNET` = 1546300800). +- **Voted-consensus activation floor: 2000** (`cblock.cpp` + `VOTED_CONSENSUS_ACTIVATION_FLOOR_TESTNET_VAL`).

The PoS and PoW +strict-enforcement sites are separate code paths; both confirmed live. +Devops payout was correct on both block types. No rejections, no +devops-fallback NOTICE, no stall.

Consumed by `removewatchonlydialog.cpp`. Required + because the three-phase prune (C.3.3) can take many seconds on + wallets with many watch-only-related historical transactions. +- `masternodeworker` — drives masternode start / stop / status + operations. Consumed by `masternodemanager.cpp`. Required + because masternode RPC paths can block on network / chain state. +- `decryptworker` — drives the recovery-phrase upgrade flow + (re-encryption of an existing wallet under the hex-derived key + so the BIP39 mnemonic unlocks it). Consumed by + `seedphrasedialog.cpp` at lines 339-353. Distinct from the + `CWallet::DecryptWallet` method (C.7), which is not called. + +**Present in source but not yet wired:** + +- `coincontrolworker` — intended to background Coin Control's + long-running select-coins operations. No GUI consumer + instantiates it; Coin Control operations currently run on the + GUI thread (which is acceptable in practice — the operations + are fast enough on typical wallets that the responsiveness gap + is small). +- `sendcoinsworker` — intended to background the `sendcoins` + validation / signing path. No GUI consumer instantiates it; + `sendcoinsdialog.cpp` performs the work on the GUI thread. + +Both unwired classes compile cleanly and their header / source +files are in the build manifest, but they are effectively +dormant code in v2.0.0.8. Listed in H.7 as a cleanup item — the +correct disposition (wire them, or remove them) is deferred. + +## F.5 Recovery phrase — old wallet upgrade flow + +For wallets encrypted with v2.0.0.6 or earlier, the recovery-phrase +upgrade is a one-time process invoked via `Settings → Recovery Phrase` +(or automatically on first unlock when the upgrade dialog determines +it's eligible). + +- `recoveryphraseupgradedialog.{cpp,h}` — explanatory dialog with + three options: proceed, decline (with confirmation), or postpone. +- `decryptworker.{cpp,h}` — background-thread re-encryption: tries + hex-derived key first (new wallets), falls back to raw password + (old wallets), then re-encrypts with hex-derived key so the + recovery phrase works going forward. +- The wallet stays encrypted throughout the process; there is no + plaintext window. + +## F.6 `guistate` namespace — per-wallet GUI preferences + +New `src/qt/guistate.{cpp,h}` centralises QSettings-backed per-wallet +flags. Two flags currently: + +- `isRecoveryPhraseUpgradeDeclined` / `setRecoveryPhraseUpgradeDeclined` +- `is2MCollateralPromptSuppressed` / `set2MCollateralPromptSuppressed` + +Keys are derived from the absolute wallet path (hashed) so multiple +wallets in different datadirs don't share state. + +## F.7 Transaction display + +- **`transactiondesc.cpp`** — Transaction-detail "Transaction ID" + suffix removed (was always `-000` because derived from a + display-row sort ordinal, not a real index). The detail line now + shows the clean transaction hash. +- **Double-click in transactions tab** now opens the detail dialog. + Previously broken via slot/signal mismatch + (`transactionview.cpp:195`); fixed by changing `SLOT` to `SIGNAL` + for `doubleClicked(QModelIndex)`. + +## F.8 Misc visual polish + +- **Balance label minimum widths** — Available, Stake, Pending, + Total, watch-only column all now have minimum widths so they don't + clip the trailing "N" in "XDN". +- **Copyright year in About dialog** — updated to 2018-2026. +- **Coin Control lock icon** — was white-on-transparent (designed + for the dark-coloured status bar); now black-on-transparent for + the default theme. +- **MAINNET indicator** in the status bar with tooltip. +- **Password generator** — 20-character cryptographically random in + `askpassphrasedialog.cpp`. +- **"Forgot password?"** link wired to the recovery-phrase unlock + flow. +- **"For staking only" checkbox** hidden by default; only shown when + a staking unlock is the explicit context. + +## F.9 Debug console parser fix + +`parseCommandLine` (`src/qt/rpcconsole.cpp`). Backslashes typed +outside any quotes were being silently consumed (treated as +bash-style escape characters with no preserved character), so a +Windows path typed without quotes like `c:\temp\test.dmp` was being +passed to the RPC as `c:tempest.dmp`. + +Symptom on `dumpwallet`: dump file silently created at the wrong +path. The user thought the file went to `c:\temp\test.dmp` but it +actually went to `/temptest.dmp` containing private keys, with +no error or warning surfaced. + +Fix: `STATE_ESCAPE_OUTER` now mirrors `STATE_ESCAPE_DOUBLEQUOTED`'s +smarter logic. Backslash is consumed only when followed by another +backslash or whitespace; every other `\X` sequence preserves the +backslash literally, so Windows paths typed without quotes now work +as users expect. + +## F.10 Qt signal/slot warnings cleared + +Five distinct slot/signal mismatches that produced runtime warnings +at startup (all gone after the fix pass): + +- `SendCoinsEntry::payAmountChanged` slot/signal mismatch +- `OptionsModel::transactionFeeChanged(CAmount)` signature mismatch +- `TransactionView::doubleClicked` slot/signal mismatch +- `DigitalNoteAmountField::textChanged` slot/signal mismatch +- Splash `showProgress` connect failure (was connecting `walletModel` + inside `setClientModel` where `walletModel` was null) + +--- + +# G. BUILD & RELEASE + +## G.1 Version stamping + +The reported version string was `v1.0.3.5-488-g-dirty` — an old +git tag, not the codebase version. `version.cpp` included a `build.h` +(generated by `share/genbuild.{bat,sh}`) which defined `BUILD_DESC` +from `git describe`. `git describe` resolves to the most recent +*reachable* tag, and this repository's most recent tag is an ancient +`v1.0.3.5` — so a v2.0.0.x codebase reported itself as v1.0.3.5. The +version string depended on git tag state, which is only verifiable +*after* a build. + +The version is now controlled entirely by source files. The +`HAVE_BUILD_INFO` / `#include "../build/build.h"` block in +`version.cpp` is commented out (not deleted — a note explains how to +reinstate git-derived build info later if wanted).

Testnet operates under + pre-swap rules (post-genesis-restart, height <<< 403117) until + testnet reaches the same height years from now. + +- **Devops-receives-on-no-masternode-found is the consensus + fallback.** When the masternode payment selector returns no + payee (typically because the producing node's local masternode + list is stale or empty — e.g. after a long stall, after restart, + during transient peer churn), the masternode share is paid to the + devops address in addition to the standard devops payment. This + is required for block validity to be independent of the producing + node's local masternode list state, and is a long-standing + consensus rule preserved unchanged in v2.0.0.8. The voted-payee + consensus (A.1), once activated, prevents the trigger condition + (stale local list) from determining the payee at all — the + canonical payee comes from queue tally, not from each node's + local lookup — but the no-payee-found fallback remains as the + ultimate safety net. + +- **Block 138092 unusual payout layout.** Confirmed consensus-valid. + See D.1.4 narrative for the full breakdown.

Note: the + function voted consensus actually uses for its denominator + (`CountVotingEligible`) is already clean and does not call + `Check()`. + +- **VRX module-global thread-safety.** `blockparams.cpp` uses + module-level globals (`fDryRun`, `bnOld`, `bnNew`, etc.) across + the retarget call chain. This is a code-hygiene concern, *not* the + D.1.3 resync determinism bug (which was purely the + `GetAdjustedTime()` read). + +- **`pindexBest` vs `pindexLast` retarget hygiene (PB-FORK).** A + retarget-hygiene cleanup; not a consensus-behaviour change. + +- **Unwired GUI worker classes.** `src/qt/coincontrolworker.{cpp,h}` + and `src/qt/sendcoinsworker.{cpp,h}` are present in the build but + have no GUI consumers in v2.0.0.8 (see F.4). The header / source + pairs compile cleanly and add a small amount of dead code to the + binary. Two valid dispositions for a future release: (a) wire + them to their intended sites in `coincontroldialog.cpp` and + `sendcoinsdialog.cpp` respectively, gaining background-thread + responsiveness for those operations; or (b) remove them from the + source tree and the build manifest. Left in place for v2.0.0.8 + because removing source files mid-release is more disruptive than + the cost of carrying dormant code; the right disposition is a + design choice for v2.0.0.9 or later. + +## H.8 Deferred to a future version + +- **Checkpoint at v2.0.1.0 rotation + 2000 blocks.** Originally + planned for v2.0.0.8; deferred because the rotation activation + block (mainnet 1,400,000 / testnet 100) does not exist yet at + v2.0.0.8 tag time. Add to `checkpoints.cpp` in v2.0.0.8.1 or + v2.0.0.9 once block 1,402,000 has been mined post-rotation on + mainnet (testnet: block 2,100). The entry takes the form + `(1402000, uint256("0x"))`. Until that checkpoint ships, + deep-reorg protection in the rotation window relies on accumulated + chain work alone. + +- **Issue 2 — chain-wide equivocation enforcement.** The + equivocation marking is per-node-local (see A.1.12). A chain-wide + enforcement design would have substantial adverse-effect risks + (fleet-wide false-positive cascade, liveness failure below + threshold, adversarial trigger amplification, asymmetric slashing, + recovery friction, operator burden, sybil amplification) if + shipped without extensive analysis. Scoped only; deferred to + v2.1+. + +- **CW3 — S2 conflicting-dsee diagnostic.** Deferred to v2.0.0.9. + +## H.9 Architectural invariants for future Rust port + +These are properties of the v2.0.0.8 design that should survive a +future re-implementation. Recorded here so a port doesn't accidentally +regress them. + +1. **Locks are user data, not masternode state.** Auto-unlocking on + stop is wrong (A.2.6). +2. **Per-output, not per-transaction.** Coin selection and lock + semantics work at the outpoint level; transaction-level filtering + produces user-visible bugs (C.2.1). +3. **Forward-compatible storage.** New BDB record types added in + v2.0.0.7/v2.0.0.8 use distinct keys and don't require migration + of existing records. +4. **Collateral by user choice.** The wallet does not auto-classify + outputs as "masternode collateral"; the user explicitly opts in + via the B1 popup, the masternode UI, or `lockunspent`. +5. **No strict version equality on protocolVersion.** Use + `>= MIN_PEER_PROTO_VERSION` everywhere, not `== PROTOCOL_VERSION`. +6. **Multi-source lock state with union semantics.** + `setLockedCoins` (in-memory) and `lockedoutput` (BDB) are merged + at load; locks set by Coin Control, `lockunspent`, and the GUI + all flow through the same mechanism. +7. **Consensus inputs are pure functions of chain.** Never of + node-local state. PB-INFLIGHT (A.1.4) is the canonical violation + to avoid. +8. **Spent-tracking via mmTxSpends, not vfSpent.** The reader-side + path that auto-handles reorgs is the correct one. vfSpent + reconciliation via FixSpentCoins is a band-aid for code that + hasn't been migrated to mmTxSpends yet (CW4 Fix C completes that + migration). +9. **Writer/reader pairing.** Whenever a code path mutates wallet + spent-state, the writer must update both vfSpent (for disk + format) and mmTxSpends (via AddToSpends → AddToWallet). The reader + should consult only mmTxSpends. CW4 Fix B + Fix C together + establish this pairing for both send and stake paths. +10. **Enforcement gates must be explicit.** A.1.7 (`fMnAdvRelay`) is + the canonical violation: consensus enforcement gated behind an + undocumented config flag named for an unrelated abandoned + feature. Never again. +11. **Chain-correction operations are canonical history.** Block + heights involved in controlled fork operations (mandatory-update + activation clusters, chain-correction rollback anchors, treasury + operations) are accepted by the validator via height-keyed + mechanisms — the `nBits` exception list for difficulty-floor + anchors, exact-height equality checks for treasury injections. + These are not bugs to be optimised away; any conforming + implementation must reproduce them exactly to validate canonical + chain history. +12. **One-shot consensus operations are pinned by exact-height + equality, never spork-gated.** The treasury injection at + `VERION_1_0_4_2_MANDATORY_UPDATE_BLOCK` is enforced by + `GetDevOpsPayment` checking `nHeight == THE_BLOCK` — a single + block, exactly. This pattern prevents replay (attacker would + have to win the chain-work race for the historical block, + computationally infeasible) and prevents accidental retroactive + application at a different height. Spork-gated activations + apply to ranges; exact-height equality applies to events. +13. **Devops as no-payee fallback is a consensus invariant.** + Block validity must not depend on the producing node's local + masternode list state. When the masternode payment selector + returns no payee, the masternode share is paid to the devops + address. This rule has held across both pre- and post-swap + reward eras, and through every other release. Voted-payee + consensus (A.1) reduces how often the fallback fires by + removing dependence on local lookups, but does not remove the + fallback itself — it remains the ultimate safety net for any + case the voted path also can't resolve. + +--- + +## Development status summary (v2.0.0.8 sealed) + +| Area | Status | +|---|---| +| Voted consensus core (A.1.1–A.1.5) | Implemented, deployed, crossing-confirmed | +| `fMnAdvRelay` gate removal (A.1.7) | Applied; enforcement confirmed at crossing | +| Engagement + vote-payee agreement (A.1.8) | Implemented, deployed | +| Vote propagation relay split (A.1.9) | Implemented, deployed | +| Validation hook (A.1.10) + CheckBlock rework (A.1.11) | Applied | +| Equivocation Issue 1 + Issue 3 (A.1.12) | Applied — 50h soak clean | +| Per-height vote path removal (A.1.13) | Applied; ~500 lines removed, 2 files deleted | +| nLastPaid correctness (A.2.1) | Resolved (all 3 sub-bugs) | +| Local MN collateral selection (A.2.7) | Resolved | +| Peer reliability fixes (A.3) | Applied | +| PoS lock-order ABBA chain (B.1) | Resolved through three iterations | +| CW4 Fix B PoS spent-tracking (B.2) | Applied; 48h parallel-wallet soak validated | +| Velocity back-off (B.3) | Resolved | +| Staking icon CW2/CW6 (B.4) | Applied; CW6 v1.1 with load-crash fix | +| CW4 Fix C reader migration (C.1.2) | Applied; smoke-test passed with 3 independent demonstrations; 48h parallel-wallet soak validated (510 mismatches / 2,978,104.26090000 XDN drift on reference wallet reconciled to zero on Fix-C wallet) | +| Balance correctness, watch-only (C.1, C.3) | Resolved | +| Wallet rebuild (C.4) | Implemented and tested | +| BIP39 (C.6) | Implemented | +| VRX recovery curve broken in v2.0.0.6 (D.1.1) | Diagnosed and superseded | +| VRX wall-clock-based curve engagement (D.1.2) | Applied (post-v2.0.0.6 work) | +| VRX retarget determinism via committed time (D.1.3) | Resolved | +| Historical mainnet `nBits` exception list extension CW8 (D.1.4) | Applied; 30 heights from full-chain scan, sorted-array + `std::binary_search` helper, log line enriched with `[PoS]`/`[PoW]` tag | +| Mining-side same-timestamp guarantee CW7 (D.1.5) | Applied — late `nBits` assignment using committed `pblock->nTime` closes the 0.7%-per-stall residual mismatch risk | +| Devops rotation + strict-check + off-by-one fix CW9 (D.1bis) | Applied — `getDevelopersAdressForHeight()` refactor, all 5 producer callers migrated, strict check re-enabled with height gate; testnet rotation block 100, mainnet rotation block 1,400,000 | +| Startup verify rollback (D.2) | Resolved with correct guard | +| Testnet construction (E.1) | Operational; soak ongoing | +| SPORK_14/15 activation crossing (E.2) | Completed — SUCCEEDED at testnet height 1837 | +| Version stamping (G.1) | Implemented | +| CI / artifact naming (G.4) | Implemented | + +--- + +*v2.0.0.8 sealed.

Verified against a fresh diff sweep of the two source trees on 2026-05-04. + +For the user-facing summary, see `RELEASE_NOTES.md`. + +--- + +## 1. Balance computation fix + +A latent bug present since at least v2.0.0.6 began surfacing in v2.0.0.7. On large wallets (hundreds of thousands of transactions, multi-second load), the staking-icon GUI poll could fire before the keystore was fully populated. `IsMine()` returned `ISMINE_NO` for outputs whose key hadn't yet been loaded, the per-transaction balance/credit caches were populated with zeros, and those zeros persisted for the rest of the session. Symptom: `getbalance` returned a value substantially below the true balance after launch, with the magnitude of the underbalance varying across cold-start runs. + +The bug was latent in v2.0.0.6 because the splash didn't refresh during wallet load. The v2.0.0.7 splash refresh (added for the maintenance-mode work, §2) drains the Qt event queue, which allows the staking-icon timer to fire mid-load and trip the bug. + +Two-part fix: + +- **Init gate.** `fWalletLoadComplete` flag in `init.cpp:82`, set true at `init.cpp:1643` after wallet load and `ReacceptWalletTransactions` complete. Two GUI poll callbacks gate on this flag and early-return: `DigitalNoteGUI::updateWeight` (`bitcoingui.cpp:1600`) and `WalletModel::pollBalanceChanged` (`walletmodel.cpp:278`). Both are externed via `init.h:21`. + +- **Cache invalidation on keystore change.** `MarkAllTxCachesDirty` (`cwallet.cpp:2582`) walks `mapWallet` and dirties every per-tx balance/credit cache. Called from nine keystore-mutation sites in `cwallet.cpp`: `AddKeyPubKey`, `AddCryptedKey`, `AddCScript`, `AddWatchOnly`, encrypted-wallet `Unlock`, and several others. Internally gated by `fWalletLoadComplete` so that the inevitable batch of mutations during wallet load does not produce N×|mapWallet| dirties — once load is complete, every subsequent runtime mutation invalidates correctly. + +Touched files: `src/init.{h,cpp}`, `src/cwallet.{h,cpp}`, `src/qt/bitcoingui.cpp`, `src/qt/walletmodel.cpp`. + +## 2. Maintenance Mode splash + +Triggers automatically on `-rebuildwallet`, `-rescan`, `-reindex`, `-iknowsalvagewalletisdangerous`, or `-maintenancemode` (`bitcoin.cpp:340-345`). Uses a separate baked-in PNG (`splash_maintenance.png` in `res/images/`) with "MAINTENANCE MODE" text rather than the standard wallet splash. Provides a chromed window with title bar, minimise button, close button, and taskbar entry — so users can see at a glance that something maintenance-y is happening rather than the normal launch flow. + +Initial implementation used runtime QPainter to draw the maintenance text on top of the standard splash. Was abandoned after the painted text exhibited progressive bolding caused by Qt repaint behaviour; baked-PNG replacement eliminated the issue. + +`splashref` is now nulled before `splash.finish()` to handle late `InitMessage` calls that would otherwise paint onto a splash about to close. + +## 3. Salvagewallet deprecation and replacement + +The decision to deprecate `-salvagewallet` was made after research into Bitcoin Core, PIVX, Dash, and Bitcoin ABC. Core removed `-salvagewallet` in 0.21.0 (PR #17219) for three reasons identified in issue #10991: default key not preserved, wallet version not preserved, and keys silently skipped. The DigitalNote codebase was hitting the third — `CWalletDB::Recover`'s inner loop uses `DB_NOOVERWRITE`, which silently drops collisions. The result is data loss in a poorly-bounded set of records. + +Two changes shipped in v2.0.0.7 that together replace salvagewallet for routine use: + +- **`-salvagewallet` now refuses to run** unless `-iknowsalvagewalletisdangerous` is also passed (`init.cpp:553-589`). Without the escape hatch, the daemon logs a clear error pointing the user to `-rebuildwallet` and exits. The escape hatch is preserved for support cases where rebuildwallet itself fails on a wallet too corrupt for cursor iteration. + + The help text for `-salvagewallet` reads "DEPRECATED -- see -rebuildwallet (Tools menu: Compact Wallet)" (`init.cpp:345`). + +- **`-rebuildwallet`** — a complete BDB-cursor-level dump-and-restore mechanism. See **Section 4** for details. + +The replaced functionality is preserved in two places: the source-level `salvagewallet` code path is untouched (escape hatch reachable via `-iknowsalvagewalletisdangerous`), and the new code at `walletdb.cpp:1175+` carries an extensive comment explaining why salvagewallet was deprecated. + +## 4. Rebuild Wallet — `-rebuildwallet` and `Tools → Compact Wallet` + +A complete BDB-cursor-level dump-and-restore mechanism that replaces `-salvagewallet` for routine wallet maintenance. Reclaims free pages, rebuilds the B-tree, and produces a smaller wallet file. Preserves every BDB record type — watch-only addresses, A4 coin locks, stealth addresses, multisig redeem scripts, the BIP39 mnemonic master key, address book entries, transaction history, locked outputs, recovery-phrase flags. Encrypted wallets stay encrypted (the mkey records are dumped as-is and restored verbatim; no password prompt during rebuild). + +### Pipeline (`walletrebuild.cpp::RebuildWallet`) + +1. **Pre-flight checks.** Refuse if `wallet.dat.bak`, `wallet.dat.new`, or `wallet.dat.dump` already exist (stale state from a previous run). Refuse if free disk space is less than 2× the source wallet size. Refuse if `wallet.dat` itself is missing. +2. **Dump.** `DumpAllRecords` cursor-walks the source wallet and writes every record to `wallet.dat.dump` in the v1 dump format (see Section 4.1 below). Read-only on the source. Permissions tightened to 0600 on POSIX. +3. **Close source.** `dbenv.Flush(false)` checkpoints the BDB log and releases all open handles to the source wallet so the env is in a clean state for the create phase. +4. **Create from dump.** `CreateFromDump` reads the dumpfile, validates the double-SHA256 checksum and record count *before* creating any destination state, then opens a fresh BDB at `wallet.dat.new` and writes every record. Uses `pdbDest->put()` with no `DB_NOOVERWRITE` flag — cursor-ordered records have no key collisions by definition, but the absent flag is defensive against a malformed dump. Records are committed in batches of 10,000 to bound BDB's dirty-page cache. A single transaction wrapping all records works on small wallets but fails with `ENOMEM` (BDB ret=12) on large ones — discovered when the 800k-record dev wallet hit the cache wall at record 172,073. Periodic commit keeps cache pressure bounded with negligible commit overhead. +5. **Verify.** `VerifyNewWallet` cursor-walks the freshly written `wallet.dat.new` and counts records, comparing to the expected count from the dump footer. Any mismatch aborts the rebuild without swapping. +6. **Swap.** Two BDB-level renames in order: `wallet.dat → wallet.dat.bak`, then `wallet.dat.new → wallet.dat`. Uses `dbenv.dbenv.dbrename()` rather than filesystem `rename()` so the env's internal log stays consistent with what's on disk. The window between the two renames is the only "danger zone" — measured in microseconds on the same filesystem — and is explicitly handled by the crash-recovery path (Section 4.2 below). +7. **Cleanup.** Delete `wallet.dat.dump`. Per Q1 default: deleted on success and failure both — privacy wins over forensic recovery, and the `.bak` is the rollback path. +8. **Outcome marker.** Write `.rebuildwallet-result` for the GUI to surface to the user on next paint. + +After `RebuildWallet` returns to `init.cpp`, `-rescan=1` is soft-set and `AppInit2` continues normally with the rebuilt wallet. + +### 4.1 Dump file format v1 + +``` +# DigitalNote wallet rebuild dump created by DigitalNote 2.0.0.7 () +# * Created on +# * Source wallet: +# * Best block at time of dump was (), +# mined on +# * Format: bdb-raw-v1 + + + +... (one record per line, BDB cursor order) + +# checksum dsha256= records= +# End of dump +``` + +Comments (`#`-prefixed) and blank lines are skipped by the parser. The checksum is the codebase-standard double-SHA256 (CHashWriter) over the per-record stream; for each record, the hash includes ``. The varint length prefix is what `CHashWriter << std::vector` produces naturally, decoupling the checksum from any future text-format changes. The `# checksum` line MUST be the second-to-last non-blank line and `# End of dump` MUST be the last; `CreateFromDump` rejects files missing either. + +### 4.2 Crash recovery + +The handler at the top of `RebuildWallet` detects a state where `wallet.dat` is missing but both `wallet.dat.bak` and `wallet.dat.new` are present — the unambiguous signature of a crash between the two renames in step 6 above. The recovery is mechanical: complete the second rename (`wallet.dat.new → wallet.dat`) and write a `recovered_from_crash` outcome marker. No user prompt; the GUI surfaces the outcome on next paint. + +### 4.3 GUI flow + +`Tools → Compact Wallet` (new top-level menu, one item) shows a confirmation dialog explaining the four ramifications: the wallet will restart, the rebuild may take minutes to hours, the wallet is unusable during, and the original is preserved as `wallet.dat.bak`. The dialog default is Cancel. On confirm: writes `.rebuildwallet-pending` to datadir, then `QApplication::quit()` — the wallet shuts down through the normal `Shutdown()` path, BDB closes cleanly, wallet.dat is consistent on disk. + +On next launch, `bitcoin.cpp`'s maintenance-mode umbrella detects `RebuildPendingFlagExists()` and uses the chromed maintenance-mode splash. `init.cpp`'s wallet block detects either `-rebuildwallet` or `RebuildPendingFlagExists()` and invokes the orchestrator. The pending flag is consumed regardless of outcome to prevent rebuild loops. + +After the rebuild attempt (success or failure), the result marker is written. The next-launched GUI's `setClientModel` schedules `showRebuildResultIfPresent()` via `QTimer::singleShot(0,...)`. That slot reads `.rebuildwallet-result`, shows a one-shot dialog with one of four messages (success / recovered-from-crash / failed-pre-swap / failed-filesystem), and deletes the marker. + +### 4.4 RPC surface + +Two hidden RPCs expose the dump and create primitives independently of the orchestrator: + +- `dumprawwallet ` — writes a v1 dumpfile from the live wallet via cursor walk. Read-only. Hidden RPC. **Note:** this RPC was implemented in the prior cycle but never registered in `crpctable.cpp` or declared in `rpcserver.h` — that omission was fixed in this cycle. Now reachable via JSON-RPC. +- `createfromdumpfile ` — reads a v1 dumpfile, validates checksum and count, writes a fresh BDB at `` within the data directory. Refuses to overwrite. Inverse of `dumprawwallet`. Hidden RPC. + +Both call into the same `walletrebuild.cpp` primitives that `RebuildWallet` uses internally; they exist for testing and advanced manual-recovery workflows. + +### 4.5 Marker-file protocol + +Two files in datadir, both leading-dot hidden: + +- `.rebuildwallet-pending` — empty file. Presence signals "perform a rebuild on next AppInit2 before LoadWallet". Written by GUI via `RebuildPendingFlagWrite()`. Consumed and removed by handler. +- `.rebuildwallet-result` — single text line + optional reason line. Written by handler at end of every rebuild attempt. Token values: `success`, `recovered_from_crash`, `failed_preswap`, `failed_filesystem`. Read and deleted by GUI on first paint. + +Both intentionally live in datadir, not in QSettings. The markers describe a property of *this* wallet.dat — not a preference of the user — so they should follow the wallet directory rather than the user's roaming profile. + +### 4.6 Files + +New / modified in this cycle: + +- `walletrebuild.h` — extended with `CreateFromDump`, `RebuildWallet`, marker helpers, `RebuildResultState` enum +- `walletrebuild.cpp` — extended with `CreateFromDump`, `RebuildWallet`, `VerifyNewWallet`, marker helpers, `DoDbRename`, `DoRename`. Existing `DumpAllRecords` from prior cycle unchanged. +- `rpcdump.cpp` — new `createfromdumpfile` RPC handler +- `rpcserver.h` — declarations for `dumprawwallet` and `createfromdumpfile` +- `crpctable.cpp` — registrations for both RPCs +- `init.cpp` — `-rebuildwallet` help text, rebuild handler block in step 5 +- `bitcoin.cpp` — `fMaintenanceMode` umbrella extended to detect the pending flag +- `bitcoingui.{cpp,h}` — Tools menu, Compact Wallet action, `compactWallet()` slot, `showRebuildResultIfPresent()` slot +- `rpcconsole.cpp` — parser fix described in §4.7 below + +### 4.7 GUI debug-console parser fix (uncovered during Rebuild Wallet testing) + +While testing `dumprawwallet` and `createfromdumpfile` from the GUI debug console on Windows, an unrelated parser bug was found in `parseCommandLine` (`src/qt/rpcconsole.cpp`). The bug: backslashes typed outside any quotes were being silently consumed (treated as bash-style escape characters with no preserved character), so a Windows path typed without quotes like `c:\temp\test.dmp` was being passed to the RPC as `c:tempest.dmp`. + +Symptom on `dumpwallet`: dump file silently created at the wrong path. The user thought the file went to `c:\temp\test.dmp` but it actually went to `/temptest.dmp` containing private keys, with no error or warning surfaced. + +Root cause: `STATE_ESCAPE_OUTER` was `curarg += ch` unconditionally, dropping every backslash. Compare to `STATE_ESCAPE_DOUBLEQUOTED` which already had the correct logic of preserving `\` for everything except `\"` and `\\`. + +Fix: `STATE_ESCAPE_OUTER` now mirrors that smarter logic. Backslash is consumed only when followed by another backslash or whitespace (preserving the niche case of `foo\ bar` → `foo bar` as a single arg). Every other `\X` sequence preserves the backslash literally, so Windows paths typed without quotes now work as users expect. + +Pre-existing bug; affected `dumpwallet`, `importwallet`, and any other RPC taking a Windows path through the GUI console. Fixed in this cycle as a side effect of testing the new RPCs. The `digitalnote-cli` command-line client and JSON-RPC HTTP interface were never affected — different code path. + +Help text for `dumprawwallet` and `createfromdumpfile` updated to recommend quoting paths in any case. Relying on the parser fix is fragile; quotation is portable across shells and survives the eventual external-cli use case. + +## 5. Cycle-2 wallet improvements + +Multiple semantic improvements to wallet code, integrated together. Each addresses a distinct correctness issue rather than a feature. + +### `AddToWallet` + +Two changes (`cwallet.cpp:2558+`): + +- **`AddToSpends(hash)` call added in the live-add (`else`) branch** (`cwallet.cpp:2625`). Previously only invoked from the `fFromLoadWallet=true` branch (`cwallet.cpp:2625` matches v2.0.0.6 line 1576). Without this, `mmTxSpends` was empty for any tx added during a rescan or live operation. Symptom: watch-only credit on a freshly-imported active address summed to roughly the total ever received rather than the current unspent balance. Self-healed on restart because wallet load re-populates `mmTxSpends` from scratch. Note: this affects watch-only credit only — `GetBalance` does not consult `mmTxSpends`. + +- **`nTimeSmart` adjustment for rescan-discovered historical transactions** (`cwallet.cpp:2709-2724`). Previously `wtx.nTimeSmart` was clamped UP to `latestEntry` (the most recent existing tx's time) when a rescan discovered an older tx. Result: all rescan-discovered txes ended up timestamped at the most recent existing tx, which is wrong. Now: if `blocktime < latestEntry`, set `nTimeSmart = blocktime` directly; otherwise apply the original clamp. + +### `GetStake` and `GetNewMint` + +`ISMINE_ALL` → `ISMINE_SPENDABLE` in the call to `GetCredit` (`cwallet.cpp:3220` and `cwallet.cpp:3242`). Was counting watch-only stake/mining-reward into the wallet's own (spendable) stake/newmint columns. Symptom: the dashboard's "Spendable Stake" column matched the "Watch-only Stake" column exactly when the wallet had no real spendable stake. Watch-only stake is now reported separately by `GetWatchOnlyStake()`. + +Verified neutral on non-watch-only wallets — the two filters evaluate identically when no watch-only addresses are present. + +### `RemoveWatchOnly` + +Substantially expanded from a one-line wrapper (`cwallet.cpp:1121+`). Now performs three phases: + +- Phase A (0-60% progress): walk `mapWallet`, identify orphan transactions whose only relevance to the wallet was via the script being removed. Outputs of these txes will return `ISMINE_NO` from `IsMine` after the script is removed, so they would appear as "(n/a)" ghost rows in the GUI if not pruned. +- Phase B (60-90%): erase orphans from `mapWallet` and from disk via `EraseTx`. Notify GUI per-erased-tx via `NotifyTransactionChanged(CT_DELETED)`. +- Phase C (90-100%): mark all remaining transactions dirty so cached watch-only credit recomputes on next access. + +Now accepts a `RemoveProgressFn` callback for GUI progress reporting (`cwallet.h:226-227`). Heavy operation on wallets with many watch-only-related historical txes (the per-tx `IsMine()` evaluation dominates wall-clock time). + +### `AvailableCoinsForStaking` + +Changed from per-transaction collateral-amount filtering to per-outpoint locking via `setLockedCoins` (`cwallet.cpp:406-456`). Previously, an entire transaction was excluded from staking if any output equalled the masternode collateral amount (2,000,000 XDN) or any output passed `IsCollateralAmount()` (multiples of 1 XDN between 1 and 5 XDN). This punished: + +- Innocent recipients of 2M XDN payments (entire tx excluded, including unrelated change outputs) +- Transactions whose change happened to land at a "collateral amount" +- Users who genuinely received 2M but didn't intend to use it as masternode collateral + +Now: only excludes outputs explicitly locked by the user via Coin Control, `lockunspent` RPC, or the masternode UI (which writes through to `setLockedCoins`). + +### `script.cpp::IsMine` — TX_PUBKEY watch-only fallback + +When a P2PK output's pubkey-derived keyID isn't in the keystore, construct the P2PKH-equivalent script and check `setWatchOnly` (`script.cpp:3470-3494`). If matched, return `ISMINE_WATCH_ONLY`. Reasoning: `importaddress` stores the P2PKH form of an address in `setWatchOnly`, but coinstakes and some receives use the P2PK form for the same logical address. Without this check, those P2PK outputs would be invisible to watch-only tracking — stake rewards (which are coinstakes paying back via P2PK) wouldn't be tracked at all. + +Verified dead code for non-watch-only wallets — `keystore.HaveKey(keyID)` returns true first, returning `ISMINE_SPENDABLE` before ever reaching this fallback. + +### `cactivemasternode.cpp::StopMasterNode` — collateral lock no longer auto-released + +Previously `StopMasterNode` called `pwalletMain->UnlockCoin(vin.prevout)` to release the collateral lock when stopping the masternode. Removed (`cactivemasternode.cpp:237-246`). + +Architectural invariant: locks are user data, not masternode lifecycle state. Auto-unlocking on stop silently undid user-set locks (including persistent locks set via the `lockunspent` RPC or via the new B2 lock controls described in §10). The user must now explicitly unlock the collateral via `lockunspent true [...]` when they actually want to spend it. The lock on masternode start (in `ManageStatus`) is retained — that protects the collateral while the masternode is running, but is no longer rolled back automatically on stop. + +## 6. BIP39 mnemonic recovery (D2 design) + +~675 lines of new functionality in `cwallet.cpp` plus the entire `src/bip39/` subdirectory. New functions: `AddMnemonicMasterKey`, `RemoveMnemonicMasterKey`, `HasMnemonicMasterKey`, plus the modification to `Unlock` that tries all master keys in `mapMasterKeys` rather than returning false on first decrypt failure. + +The wallet stores two `CMasterKey` envelopes encrypted under different keys. `CMasterKey[1]` decrypts under the password-derived hex key; `CMasterKey[2]` decrypts under the recovery-phrase-derived hex key. Both unlock the same `vMasterKey`. `Unlock` and `ChangeWalletPassphrase` were both modified to iterate all master keys (`continue` instead of `return false` on first decrypt failure). + +**Design D2 — recovery phrase derives from `vMasterKey`, not from the password.** `AddMnemonicMasterKey` takes no arguments; it derives the mnemonic from the wallet's `vMasterKey` directly. This means the 24-word recovery phrase is **stable across password changes** — once a wallet has been BIP39-upgraded, the recovery phrase the user wrote down stays valid even after a `walletpassphrasechange`. `CMasterKey[2]` is rotated with the new password but the underlying `vMasterKey` (and therefore the mnemonic) doesn't change. This was originally noted as a v2.0.0.8 candidate in Claude 1's design notes; verified shipped in v2.0.0.7. + +GUI: new dialogs `recoveryphraseupgradedialog`, `rotatephrasedialog`, `seedphrasedialog`. Centralised GUI state management via the new `guistate` namespace (see §11). + +New RPC: `getrecoveryphrase` (in `rpcbip39.cpp`). + +## 7. Wallet decryption code (NOT CALLED, retained) + +`DecryptWallet` (~200 lines, `cwallet.cpp:1644-1791`). Two-phase commit: writes all plain keys with overwrite first, then erases encrypted records, so a mid-operation crash leaves wallet.dat in a recoverable state. Also writes a safety backup file (`decrypt_wallet_backup.txt`) before any modification, deleted on success. + +Marked "NOT CALLED — retained for future use" in source. The Settings menu shows a "Decrypt Wallet..." label when the wallet is locked, but the action is permanently disabled (`bitcoingui.cpp:1378-1380`); there is no live path to invoke `DecryptWallet`. The function is kept in the tree for future development but is not exposed in v2.0.0.7. + +## 8. Worker thread infrastructure + +Five new worker-thread classes added to keep the GUI responsive during slow wallet operations: + +- `coincontrolworker` — CoinControl operations off the GUI thread +- `decryptworker` — `DecryptWallet` off the GUI thread (NOT CALLED in v2.0.0.7, see §7) +- `masternodeworker` — masternode operations off the GUI thread +- `sendcoinsworker` — `sendcoins` off the GUI thread +- `watchonlyworker` — `RemoveWatchOnly` (with progress callback) off the GUI thread + +Each is a `.cpp` + `.h` pair under `src/qt/`, registered in `include/app/sources.pri` and `include/app/headers.pri`. + +## 9. Masternode fixes + +Five independent bugs fixed: + +- **`getblocktemplate` always returned the same masternode winner** (`rpcmining.cpp:841-857`). The old code called `GetCurrentMasterNode(1)` which passed no block height, defaulting to height 0 (genesis block hash) inside `CalculateScore()`. The same masternode won every block indefinitely. Fix: replaced with `masternodePayments.GetBlockPayee(pindexPrev->nHeight + 1, mnPayee, mnVin)` — same data source as block validation. Added `FindOldestNotInVec` fallback for when `vWinning` is empty (transition period while network upgrades). + +- **All masternodes displayed the same "last paid" time** (`cmasternode.cpp`). Two bugs in the same field: + 1. **Copy constructor** had two consecutive assignments: `nLastPaid = other.nLastPaid` followed by `nLastPaid = GetAdjustedTime()`. The second line overwrote the real last-paid time with the current time on every copy. Second line removed. + 2. **The `newAddr`/`newVin`/`newPubkey` constructor** (used when a peer's `dsee` arrives and a fresh `CMasternode` is constructed) never initialised `nLastPaid` at all. The field held uninitialised stack memory — typically a small repeating value like `17` — until the MN was actually paid (when `main.cpp:2202` would update it). Added `nLastPaid = GetAdjustedTime()` so newly-Registered MNs show "now" until first payment, matching the default constructor's semantics. UAT-discovered post-batch-1 when masternode list output showed `lastpaid: 17` for nodes that had never been paid through the observer wallet's view. + Together these fix the "last paid" display so it always shows a real timestamp. + +- **Masternodes stopped activating across minor version differences** (`cmasternodeman.cpp:901`). `EnableHotColdMasterNode` check was `protocolVersion == PROTOCOL_VERSION` — a strict equality that broke as soon as wallet and daemon were on different builds. Changed to `protocolVersion >= MIN_PEER_PROTO_VERSION`. Any acceptable version now activates the masternode regardless of minor version differences. + +- **`AvailableCoinsMN` no longer filters out locked outputs on the masternode-start path** (`cwallet.{h,cpp}`, `cactivemasternode.cpp:618`). New parameter `bool fIncludeLockedMN = false` on `AvailableCoinsMN`; the `IsLockedCoin` filter in the per-output predicate becomes `(fIncludeLockedMN || !IsLockedCoin(...))`. `SelectCoinsMasternode` passes `true`. **Production bug**: from cycle 2 onwards, locks are persistent (BDB record type A4 `lockedoutputs`); pre-cycle 2 they were in-memory only and re-evaporated on every restart. The `AvailableCoinsMN` lock-filter was originally a "this collateral is in use by another MN" check, but with locks now persistent, it incorrectly treated user-locked collaterals (and the wallet's own auto-locked collaterals from line-144 `LockCoin`) as unavailable. Symptom: re-Register after a restart fails with `"could not allocate vin"` whenever the collateral has been locked. Hit production with 3 of 20 masternodes failing simultaneously after a "send all available" + restart cycle. Fix architecturally aligns with invariant 1: locks are user data, not MN state. + +- **Remote masternode start now auto-locks the collateral** (`cactivemasternode.cpp` inner `Register(CTxIn, CService, ...)` at the success path before `return true`). The local-MN path (`ManageStatus()` line 144) has always called `pwalletMain->LockCoin(vin.prevout)` after a successful Register; the remote-MN outer `Register(strService, strKeyMasternode, txHash, strOutputIndex, ...)` did not. Asymmetry meant remote-MN operators had to manually lock collaterals to get the same protection local-MN operators got automatically. Fix: added `LockCoin` to the inner Register's success path under `LOCK(pwalletMain->cs_wallet)`, gated on `!IsLockedCoin` to be idempotent. Both paths now protect collateral identically. Required `#include "thread.h"` for the `LOCK` macro. + +## 10. Unit B — Masternode collateral UX + +Six changes that together turn the 2M XDN collateral UTXO into a first-class concept the user can manage from the GUI. + +- **B1: 2M XDN incoming-collateral popup** (`bitcoingui.cpp:1015-1079`). When a transaction lands an output equal to the masternode collateral amount, the user is prompted with three choices: "Lock as collateral" (calls `walletModel->lockCoin`), "Not now" (no action; will prompt again on the next 2M arrival), or "Don't ask for this wallet" (sets a per-wallet QSettings flag via `GuiState::set2MCollateralPromptSuppressed`). Defensive re-check before showing the prompt: if the outpoint is already locked, return without prompting. + +- **B2: Lock/Unlock context menu on the user's own masternodes table** (`masternodemanager.{h,cpp,ui}`). New `ownContextMenu` with `lockCollateralAction` and `unlockCollateralAction`. Selectively enables Lock or Unlock based on the current row's UTXO lock state. New helper `refreshCollateralCell(int row)` updates the Lock column from `CWallet` via the model. Right-click sets `ownContextMenuRow` to the click-target row (not selected row) — selection-based dispatch was the original implementation and led to "right-click row 5, action fires on row 1" surprises. Right-click also clears prior multi-selection and selects the click-target row, so visible selection always matches what menu actions and Stop/Start/Edit buttons will operate on. + +- **B3: Masternode list selection mode** (`masternodemanager.ui`). Initially `QAbstractItemView::SingleSelection` → `QAbstractItemView::MultiSelection`, then changed to `QAbstractItemView::ExtendedSelection` for standard Windows-like behaviour: click replaces selection, Ctrl-click adds, Shift-click range-selects. Replaces "every click toggles" multi-selection that required explicit unselect. + +- **B4: Lock column in My Master Nodes table** (`masternodemanager.ui`, `masternodemanager.cpp`). New 4th column "Lock" with closed-padlock icon and "Locked" or "Unlocked" text per row, sourced via `walletModel->isLockedCoin`. Initially the runtime code was writing to column 3 with only 3 columns declared in the .ui (silent setItem failure); the form fix declares the 4th column. Required `bitcoingui.cpp` to call `masternodeManagerPage->setWalletModel(walletModel)` (had been missing entirely — `walletModel` was `null` for the lifetime of the page, making `refreshCollateralCell` early-return). Required `MasternodeManager::showEvent` override to call `on_UpdateButton_clicked()` so the table populates immediately when the page is shown (without it, lands on last-selected tab and `currentChanged` doesn't fire). + +- **B5: Lock column spacing** (`masternodemanager.cpp:108`). Disabled `stretchLastSection` (was making the Lock column eat the full row width when ResizeToContents shrunk the others) and added 8px cell padding via stylesheet so columns aren't packed tight against neighbours. + +- **B6: Locked Outputs dialog** (new files: `lockedoutputsdialog.{h,cpp}`, `forms/lockedoutputsdialog.ui`; `walletmodel.{h,cpp}` additions). Modal dialog opened from `Tools → Locked Outputs...`. Six columns: Lock indicator / Address / Label / Amount / Type / TXID:vout. Three-tier classification driven by `WalletModel::listLockedOutputsWithDetails` which walks `setLockedCoins`, joins to `mapWallet` for amounts, parses `masternodeConfig.getEntries()` once into a lookup map (O(N+M) not O(N*M) for N locks and M MN entries), filters watch-only outputs, classifies into `LOT_MASTERNODE` / `LOT_MN_COLLATERAL_AMOUNT` / `LOT_OTHER`, sorts (configured MNs first). Per-tier confirmation messages on unlock — most severe for configured MN ("the masternode will permanently fail"), middle for 2M-not-configured, mildest for other. Right-click context menu (Copy txid / Copy address / Copy amount / Unlock collateral) acts on right-clicked row with selection narrowed to match. Double-click any cell toggles. Refreshes on every toggle and on `showEvent`. New struct `LockedOutputDetail` lives in `walletmodel.h`; required `coutpoint.h` include there (forward declaration of `COutPoint` was sufficient for member function signatures but not for value-typed struct members). New BDB record type was already added in cycle 2 (A4 `lockedoutputs`); no schema additions needed for B6. + +## 11. `guistate` namespace — per-wallet GUI preferences + +New `src/qt/guistate.{cpp,h}` centralises QSettings-backed per-wallet flags. Two flags currently: + +- `isRecoveryPhraseUpgradeDeclined` / `setRecoveryPhraseUpgradeDeclined` — persists the user's decision to decline the BIP39 recovery-phrase upgrade prompt. Without this, the prompt would re-fire on every unlock of an old wallet. + +- `is2MCollateralPromptSuppressed` / `set2MCollateralPromptSuppressed` — per-wallet opt-out for the B1 2M collateral popup. + +Keys are derived from the absolute wallet path (hashed) so multiple wallets in different datadirs don't share state. QSettings auto-syncs in its destructor; the setters force a sync immediately so the flag survives a crash before Qt's normal sync window. + +## 12. Recovery phrase — old wallet upgrade flow + +For wallets encrypted with v2.0.0.6 or earlier, the recovery-phrase upgrade is a one-time process invoked via `Settings → Recovery Phrase` (or automatically on first unlock when the upgrade dialog determines it's eligible). + +- `recoveryphraseupgradedialog.{cpp,h}` — explanatory dialog with three options: proceed, decline (with confirmation), or postpone. +- `decryptworker.{cpp,h}` — background-thread re-encryption: tries hex-derived key first (new wallets), falls back to raw password (old wallets), then re-encrypts with hex-derived key so the recovery phrase works going forward. +- The wallet stays encrypted throughout the process; there is no plaintext window. + +## 13. Splash, GUI, and theme work + +Already documented in user-facing notes. Technical points: + +- Splash is `480×462px` with `Qt::WA_TranslucentBackground` (light theme) or opaque (maintenance mode). +- Dark theme is a Qt stylesheet applied to all top-level widgets at startup via `bitcoin.cpp`. Toggle persists across sessions via the existing options-model preference. +- New 16/32/48/64/128/256 PNG icons; new multi-resolution `DigitalNote.ico`. +- Password generator: 20-character cryptographically random in `askpassphrasedialog.cpp`. +- "Forgot password?" link wired to the recovery-phrase unlock flow. +- MAINNET indicator with tooltip in the status bar. +- "For staking only" checkbox hidden by default; only shown when a staking unlock is the explicit context. + +## 14. Build, infrastructure, and CI + +- `clientversion.h`: BUILD bumped 6 → 7. +- `version.h`: `PROTOCOL_VERSION` 62054 → 62055; `MIN_PEER_PROTO_VERSION` unchanged at 62052. +- BIP39 library merged inline (`src/bip39/`); previously a git submodule. CI workflows updated to `submodules: false`. +- **`USE_BIP39` build flag retired.** The opt-out path was already non-functional in the source tree because BIP39 calls were woven into `cwallet.cpp`, `qt/askpassphrasedialog.cpp`, `qt/walletmodel.{cpp,h}`, and `qt/seedphrasedialog.{cpp,h}` without `#ifdef` guards. CI always passed `USE_BIP39=1` so nobody had been exercising `USE_BIP39=0`. Three files de-conditionalised: `include/libs/bip39.pri` (removed the `contains(USE_BIP39, 1) { ... }` wrapper, body is now unconditional), `src/rpcserver.h` and `src/crpctable.cpp` (removed `#ifdef USE_BIP39 ... #endif` around `getrecoveryphrase` declaration and registration). CI workflows still pass `USE_BIP39=1` harmlessly (defines are unconditional in `bip39.pri` now). BIP39 is now load-bearing for the wallet UX and not optional. +- New build infrastructure: `include/libs/bip39.pri`, `include/libs/gmp.pri` (GMP added for BIP39 arithmetic). +- 11 new sources and 9 new headers registered in `include/app/sources.pri` and `include/app/headers.pri`. +- `DigitalNote_config.pri` Linux block uncommented and activated (was entirely commented out in v2.0.0.6, causing all header lookups to fail on Linux). +- Linux `MINIUPNPC_API_VERSION=18` defined explicitly via `DEFINES +=` in `DigitalNote_config.pri`. The Makefile.mingw used to compile miniupnpc 2.2.8 doesn't define the API version macro correctly in installed headers on Linux. +- `net.cpp:1316-1322` — explicit `#if MINIUPNPC_API_VERSION >= 18` branching for the `UPNP_GetValidIGD` signature change in API v18. +- BIP39 `#include` paths changed from `"bip39/xxx.h"` (quoted) to `` (angle brackets) to use the `INCLUDEPATH` from `bip39.pri` rather than the source-relative search. +- `cdb.cpp` — explicit template instantiations for `CDB::Erase` and `CDB::Erase>`. Without these the linker can't resolve `EraseRecoveryPhraseFlag` and `EraseMasterKey`. +- GitHub Actions workflows: Linux x64, Linux aarch64, macOS Intel + Apple Silicon, Windows MSYS2. Tag-driven release workflow auto-builds all platforms and publishes a GitHub Release with binaries and SHA256SUMS. +- **Release artifact naming convention changed.** Previous convention: `DigitalNote-qt..` and `DigitalNoted..` (with no version, no separator consistency). New convention: `---.`. Examples: `DigitalNote-qt-2.0.0.7-win-x64.exe`, `DigitalNote-qt-2.0.0.7-linux-arm64`, `DigitalNoted-2.0.0.7-macos-x64.dmg`. OS values: `win`, `linux`, `macos`. Arch values: `x64`, `arm64`. **32-bit builds dropped** (previously `linux.i386` and `win32`); **macOS Apple Silicon native build added** (previously Intel-only). +- **`linux-x64-compat` build variant added** for older Linux distributions. Standard `linux-x64` builds against Ubuntu 24.04+ (glibc 2.39+, libstdc++ 14+) and fails on systems with older C runtimes with `GLIBC_2.x not found` or `GLIBCXX_3.4.x not found` errors. The compat variant builds against an older glibc baseline (2.31+, covering Ubuntu 20.04, Debian 11, RHEL 9) and statically links libstdc++ so the binary doesn't depend on the host system's libstdc++ at all. Same source tree, same `.pro` files; the difference is purely in the CI runner image (older Ubuntu LTS) and the LIBS line including `-static-libstdc++ -static-libgcc`. Both `DigitalNote-qt` and `DigitalNoted` ship in the compat flavour. Users on bleeding-edge systems get the smaller standard `linux-x64` build; users on older LTS distributions or RHEL/CentOS-derived systems use `linux-x64-compat`. No source code differences — both variants compile from identical sources. + +## 15. New BDB record types + +- `lockedoutput` — persistent UTXO lock (per-outpoint, replaces transaction-level filtering, see §5 `AvailableCoinsForStaking`) +- `recoveryphraseflag` — marker that the wallet has been BIP39-upgraded +- `EraseLockedOutput`, `EraseRecoveryPhraseFlag` — corresponding erase helpers +- `EraseCryptedKey`, `EraseMasterKey`, `WriteKeyOverwrite`, `EraseTx` — primitives used by `RemoveWatchOnly` (§5) and the (NOT CALLED) `DecryptWallet` (§7) + +All registered in `walletdb.h:50-82`. + +## 16. New tests + +`src/test/`: amount, hash, script, spork, transaction, util, version (7 new files). +`src/qt/test/`: walletmodel. +`test/bip39/`: test_bip39_wallet (top-level, BIP39 vector tests). +`test/integration/`: test_entropy_boundaries, test_mnemonic_roundtrip, test_seed_vectors. +`test/qt/`: test_seedphrasedialog. + +## 17. Other additions + +- `removewatchonlydialog.{cpp,h}` — bulk remove watch-only addresses GUI (paired with `RemoveWatchOnly` progress reporting from §5). +- `removeaddress` RPC — wraps `RemoveWatchOnly`. Registered at `crpctable.cpp:105`. +- `dumprawwallet` RPC (hidden) — see §3 / §4. Walks every BDB record via cursor and writes a versioned dumpfile. + +## 18. Known issues at release + +- **`importwallet` GUI freeze with icon errors** — `qt_imageToWinHBITMAP` and `QPixmap::fromWinHICON` failures spam the log thousands of times during/after `importwallet` on a wallet with substantial tx history. The `ShowProgress(0)/ShowProgress("",100)` toast-suppression added in cycle-2 doesn't fully suppress notifications during the import path. GUI becomes unresponsive though wallet thread (and RPC) remain healthy. Workaround: use Compact Wallet (§4) for routine maintenance rather than `dumpwallet`+`importwallet`. + +- **`stop` RPC weak guarantees on busy wallet** — needed multiple invocations during a recently-imported wallet's post-load settling phase. Will be addressed alongside the underlying responsiveness work in a future cycle. + +## 18.1 Bug fixes for issues called out in prior cycle's "must address before release" + +- **Splash `showProgress` connect failure** (was: `bitcoingui.cpp:600` connected `walletModel` to `showProgress` inside `setClientModel(ClientModel*)` where `walletModel` was null) — **fixed**. The connect now lives in `setWalletModel()` where `walletModel` is guaranteed non-null. Stale Qt warning at startup is gone. + +- **`SendCoinsEntry::payAmountChanged` slot/signal mismatch** (was: `sendcoinsentry.cpp:79` used `SLOT(payAmountChanged())` for what is actually a relay signal declared in the `signals:` section) — **fixed**. The connect now uses `SIGNAL(payAmountChanged())`, properly forwarding the amount field's `textChanged()` to listeners on `SendCoinsEntry` (`SendCoinsDialog` listens for it at line 419 to refresh coin-control labels). + +- **`OptionsModel::transactionFeeChanged(CAmount)` signature mismatch** (was: signal declared as `transactionFeeChanged(qint64)` but `sendcoinsdialog.cpp:170` connected to `transactionFeeChanged(CAmount)` — Qt's string-based connect treats these as different types even though both are `int64_t`) — **fixed**. Signal redeclared as `transactionFeeChanged(CAmount)` to match the connect, with `#include "types/camount.h"` added to `optionsmodel.h`. + +- **`TransactionView::doubleClicked` slot/signal mismatch** (was: `transactionview.cpp:195` used `SLOT(doubleClicked(QModelIndex))` for what is actually a relay signal on TransactionView declared at line 97 of the header) — **fixed**. The connect now uses `SIGNAL(doubleClicked(QModelIndex))`, properly forwarding the inner table view's doubleClicked to listeners on TransactionView (`bitcoingui.cpp:274` listens to it to call `showDetails()`). + +- **`DigitalNoteAmountField::textChanged` slot/signal mismatch** (was: `bitcoinamountfield.cpp:39` used `SLOT(textChanged())` for what is actually a relay signal declared at `bitcoinamountfield.h:48`) — **fixed**. Same pattern as the SendCoinsEntry fix above; the inner spinbox's `valueChanged(QString)` is now correctly forwarded as the AmountField's own `textChanged()` signal. Listeners include `sendcoinsdialog` and `sendcoinsentry`. + +- **"Coinstake as individual tx" errors at startup** (was: `cwallet.cpp::ReacceptWalletTransactions` fired `AcceptToMemoryPool` for orphaned coinstakes, generating ~1378 error log lines per launch on the dev wallet) — **fixed**. The check at `cwallet.cpp:2997` excluded coinbase but not coinstake; mirrored the symmetric coinbase/coinstake handling already present at line 3005. One-line addition: `!wtx.IsCoinStake() &&`. Removes the largest single source of debug.log noise at startup. + +- **Rescan splash freeze** (was: `init.cpp` startup `-rescan` showed "Rescanning..." once then the splash sat unchanged for the duration of the scan, sometimes minutes) — **fixed**. Added `uiInterface.InitMessage` calls inside `ScanForWalletTransactions`: an entry-point message ("Rescanning... 0 / N") and per-batch updates every 5000 blocks ("Rescanning... block M / N"). The existing `ShowProgress` calls go to wallet model listeners which aren't wired during the init-time path; `InitMessage` paints synchronously to the splash while it's alive and is a no-op afterwards. Same code path serves both `-rescan` startup and runtime `importaddress`/`importwallet` rescans (the latter already had a separate progress dialog via the wallet model). Compact Wallet's post-rebuild rescan also benefits. + +- **Win11 tray icon size warning** (was: `QSystemTrayIcon::showMessage: Wrong icon size (32x32), please add standard one: 24x24`) — **fixed**. The tray icon resource alias `:/icons/toolbar` was bound to `digitalnote-16.png` (a fixed 16x16 PNG); repointed to `digitalnote.ico` which contains 16/24/32/48/64/128/256 entries, so Qt picks the right size for the platform. New 24x24 standalone PNG also added (`digitalnote-24.png`). All icons (existing and new) refreshed to a consistent visual generation. + +- **`-salvagewallet` help text references `-rebuildwallet`** (was: prior cycle's note flagged this as needing verification — help text said "DEPRECATED -- see -rebuildwallet (Tools menu: Compact Wallet)" but those features didn't yet exist) — **resolved**. Both `-rebuildwallet` and `Tools → Compact Wallet` ship in v2.0.0.7 (§4). Help text is accurate. + +## 18.2 Polish items + +- **Copyright year update.** `aboutdialog.ui:101` updated from "2018-2020 The DigitalNote Developers" to "2018-2026 The DigitalNote Developers". `bitcoingui.cpp:5` already said 2018-2026. +- **Balance label width.** Nine balance labels on the overview page (`labelBalance`, `labelStake`, `labelUnconfirmed`, `labelTotal`, `labelImmature`, `labelWatchAvailable`, `labelWatchStake`, `labelWatchPending`, `labelWatchImmature`, `labelWatchTotal`) had no minimum width. Bold text rendering occasionally produced a slightly-too-narrow label that clipped the trailing "N" in "XDN". Added `minimumSize: 140x0` to all nine. Matches the pattern already in use for the watch-only column separator at line 205. +- **Menu reorganization.** The Tools menu (introduced this cycle for Compact Wallet) now also holds Show Backups, Check Wallet, and Repair Wallet — these were previously in Settings. The split is conceptual: Settings holds security state and preferences (Encrypt, Change Passphrase, Unlock variants, Lock, Recovery Phrase, Options); Tools holds maintenance operations. +- **Maintenance splash always-on-top.** The chromed maintenance-mode splash now uses `Qt::WindowStaysOnTopHint` like the normal startup splash. Previously a long-running maintenance operation could end up buried under MSYS2 / IDE / etc. windows. Tray-icon minimise/restore is unaffected (always-on-top governs Z-order while visible; `hide()` works regardless). + +## 19. Pre-existing background noise (not regressions) + +Known issues that existed in v2.0.0.6 and continue to exist in v2.0.0.7. Documented for awareness, not for v2.0.0.7 fixing. + +- **Pre-wallet-load delay on 800MB wallets** — post-splash close, pre-window open. Caused by `TransactionTableModel::refreshWallet()` walking `mapWallet` on the GUI thread under `cs_main + cs_wallet`, calling `decomposeTransaction` for each. On 780k-record wallets this is several minutes. Fix is incremental load with worker thread and `rowsInserted` signals; deferred to v2.0.0.8. +- **2-7 second `getinfo` response time on 800MB wallets** — O(n) walk in some RPC layer. Performance, not regression. +- **2.0.0.6 splash shows two "Rescanning..." messages with different fonts** — likely two distinct `InitMessage` callers, one going through HTML formatting flag. Cosmetic only. +- **Toast notification spam** during `importwallet` and similar runtime operations on the GUI thread — the existing `ShowProgress(0/100)` batching mechanism in `transactiontablemodel.cpp` and `walletmodel.cpp` doesn't fully suppress notifications during the import path. GUI becomes unresponsive though wallet thread (and RPC) stay healthy. Workaround: use Compact Wallet (§4) instead of dumpwallet+importwallet for routine maintenance. Investigation deferred to v2.0.0.8. +- **`stop` RPC weak guarantees on busy wallet** — needs multiple invocations during a recently-imported wallet's post-load settling phase. Will be addressed alongside the responsiveness work. + +## 20.

Noting here so the next maintainer has a clean inventory rather than having to scan back through working notes. + +### High-value, deferred for risk/scope reasons + +- **5b — Periodic lock release in `ScanForWalletTransactions`.** Currently holds `LOCK2(cs_main, cs_wallet)` for the entire chain scan, blocking GUI and RPC. Fix: release/reacquire periodically with `FindBlockByHeight(nLastHeightProcessed + 1)` for reorg recovery. Estimated 2 hours + thorough testing; silent-failure mode (transactions silently skipped during reorg-overlapping-rescan) makes this risky to ship without unit-test coverage we don't have. + +- **`TransactionTableModel::refreshWallet()` incremental load.** This is the 10-15 minute pre-window-open delay on the dev wallet. Fix: walk `mapWallet` in batches, release/reacquire `cs_wallet` between batches, emit `rowsInserted` to populate the table progressively. Touches the GUI thread model and could expose ordering bugs that haven't surfaced before because everything was atomic. Several hours of careful work + testing. + +- **Toast popup spam during `importwallet` and similar.** Existing `ShowProgress(0/100)` batching mechanism in `transactiontablemodel.cpp` and `walletmodel.cpp` doesn't fully suppress notifications during the import path. GUI becomes unresponsive though wallet thread (and RPC) stay healthy. Investigation deferred — needs a clean reproducer. + +### Low-priority + +- **2-7 second `getinfo` response time on busy wallets.** Pre-existing. O(n) walk somewhere in the RPC layer. +- **`stop` RPC weak guarantees on busy wallet** — needs multiple invocations during a recently-imported wallet's post-load settling phase. +- **`CWalletDB::Recover` has the same single-txn-all-records ENOMEM pattern** that hit Compact Wallet (now fixed). Trivial to apply the same periodic-commit fix there. Salvagewallet is deprecated and rarely run on wallets large enough to trigger this, so low priority. +- **`TransactionTablePriv::refreshWallet` rescan progress label cosmetic polish.** Currently shows "block N / TOTAL" where N jumps to ~99% on first message because `nBlocksScanned` only increments for blocks past the wallet birthday. Could track *blocks-actually-scanned* vs *total-blocks-actually-needed* (computed from `nTimeFirstKey`) for a more meaningful label. +- **Per-UTXO labels for locked outputs.** The Locked Outputs dialog (B6) shows the address-book label, but a user with multiple locked UTXOs at the same address can't distinguish them with custom labels ("Bob's birthday gift" vs "cold storage savings"). Implementation: new BDB record type A5 `lockedoutputlabel:: -> ` with `WriteLockedOutputLabel` / `EraseLockedOutputLabel`, `LoadLockedOutputLabels` cursor walk. Add inline edit support to the dialog. Compact Wallet will handle the new record type transparently via cursor-walk dump-and-restore — no migration needed. Estimated 3-4 hours including test. Punted from v2.0.0.7 to keep B6 scope tight; address-book label is good enough for the masternode-collateral case which is the dominant use of locks. +- **Live-update on external lock changes in Locked Outputs dialog.** The dialog refreshes on every toggle and on showEvent, but external changes (e.g. `lockunspent` from RPC while the dialog is open) aren't reflected until the user closes and reopens. Adding a wallet-level "locks changed" signal and connecting from the dialog is the right fix; punted because the existing wallet doesn't expose such a signal. +- **"Show transaction details" right-click item in Locked Outputs dialog.** Would open the standard `TransactionDescDialog` showing block height, confirmations, full inputs/outputs. Requires looking up the matching `QModelIndex` in the proxied `TransactionTableModel` from the locked-output `txid`, which is cross-model plumbing that wasn't worth the complexity for v2.0.0.7. The Copy txid action in the right-click menu provides a workaround (paste into Debug Window's `gettransaction ` for the raw RPC equivalent). + +### Probational deferral + +- **CheckBlock log message** — `"PoS Recipient masternode address validity skipping, Checks delay still active!"` appears on load. Mechanism is the 45-minute masternode-checks-delay grace period after startup or post-IBD; one occurrence on load is expected behaviour. **Will be a real bug only if the message keeps appearing every block more than 45 minutes after the wallet has finished syncing.** Watch for it; flag if it persists. + +### Future version (not v2.0.0.8) + +- **Dev address rotation.** Address `dafC1LknpDu7eALTf5DPcnPq2dwq7f9YPE` is set in `src/fork.h:60` as `VERION_1_0_4_2_DEVELOPER_ADDRESS`, consumed by `getDevelopersAdress()` in `src/fork.cpp`, validated in `cblock.cpp:1305`. Consensus-critical — requires a hardfork at activation block. Pattern is well-precedented (rotated in v1.0.1.5 and v1.0.4.2). Recommendation: target ~200k blocks future activation in v2.0.1.0 or later release; generate fresh address from never-used wallet on hardware controlled by team; masternodes upgrade first, then mining pools, then stakers, then full nodes. NOT in v2.0.0.7 or v2.0.0.8. + +--- + +## 22. Release workflow + +The GitHub Actions release workflow was rewritten in this cycle to ship per-binary downloads with the new naming convention.

The active mainnet is on v2.0.0.6; v2.0.0.7 and +intermediate v2.0.0.8 work never shipped publicly. This release bundles +the entire accumulated body of fixes, features, and improvements built +between v2.0.0.6 and the v2.0.0.8 sealing point. + +The headline feature is **masternode voted-payee consensus**, an explicit +signed-voting protocol that replaces the loose locally-computed payment +selection of prior versions. The release also includes substantial work +in the proof-of-stake path, the wallet GUI, balance correctness, +masternode peer handling, the build and release infrastructure, and a +purpose-built v2.0.0.8 testnet established specifically for validating +the new consensus mechanism. + +This release is **chain-compatible** with v2.0.0.6 until the new +consensus feature is activated by the network spork key. + +--- + +## 🗳️ Masternode Voted Consensus (headline feature) + +v2.0.0.8 introduces **voted-payee consensus** for masternode payments. + +In v2.0.0.6, the masternode paid in each block was chosen by each node +locally with only loose coordination, which could lead to disagreement +about who should be paid. v2.0.0.8 replaces this with an explicit, +signature-verified voting system based on **per-masternode ordered +queues** of upcoming payees: + +- Each masternode broadcasts a **signed queue** of the next 10 payees, + computed by the same deterministic forward-simulation on every node. +- Every node tallies the queues it receives by position. +- When a supermajority of eligible masternodes agree on the payee for a + given position, that payee becomes the **canonical** payee for that + block height. +- Block validation then enforces the agreed payee. + +Because every masternode computes the schedule by the same deterministic +rule (and advances each chosen payee's simulated last-paid height before +picking the next position), the queues agree position-for-position and +payments rotate cleanly and fairly. The result is that all nodes agree +on masternode payments by an auditable, signature-verified vote rather +than by independent local guesswork. + +### Activation + +Voted consensus does **not take effect** until a set activation height. +Until activation: +- The network behaves exactly as v2.0.0.6 did for payment selection. +- Upgrading to v2.0.0.8 is safe and the new behaviour is inert on + existing chain history. + +After activation: +- Every block at or above the activation height is validated against + the voted canonical payee. +- If voted consensus has insufficient coverage at activation height + (e.g. partial network upgrade, transient masternode outage), the + chain falls back to the legacy payment rule until coverage forms. + This is a deliberate **soft activation** to avoid chain stalls. + +The activation height has a fixed floor (`INT_MAX` in this release, +meaning the feature is off until further notice) and can only be +brought *forward* by the network spork key (`SPORK_15`), never pushed +back beyond the floor. The activation is a one-way upgrade. + +This feature has been validated on the v2.0.0.8 testnet through +multi-day soak runs, stress tests covering peer churn and restarts, +SPORK_14/15 rehearsal, and a controlled activation crossing at testnet +height 1837 — block 1837 (PoW) and block 1838 (PoS) both accepted +with 7/7 voter consensus. + +--- + +## ⛏️ Masternode Fixes + +### Payment selection and last-paid tracking + +- **Fixed: `getblocktemplate` always returned the same masternode + winner** — the old code used the genesis block hash (height 0) in its + score calculation, causing the same masternode to win every block + indefinitely. Now reads from the same authoritative payment record as + block validation, with a `FindOldestNotInVec` fallback for transition + periods. +- **Fixed: all masternodes displayed the same "last paid" time** — two + bugs in the same field: a copy constructor was overwriting the real + last-paid time with the current time on every copy, and a peer-driven + constructor was leaving the field as uninitialised stack memory until + first payment. Both fixed. +- **Fixed: "last paid" display did not reflect voted consensus + payments** — a second redundant `nLastPaid` writer in `main.cpp` + `ProcessBlock` was clobbering the correct value set by + `OnBlockConnected`. The redundant writer is removed; `OnBlockConnected` + is now the single authority. + +### Masternode start and activation + +- **Fixed: masternodes stopping when collateral wallet version differs + from remote daemon** — the version check was too strict; masternodes + now activate correctly across minor version differences between + wallet and daemon. +- **Fixed: masternode start failing with "could not allocate vin" when + collateral is locked** — the candidate-selection path no longer + filters out locked outputs. Locked collaterals are normal (they're + the wallet's own protective signal that an MN is in active use), and + the start path now correctly recognises them as valid. +- **Fixed: local masternode start ignored masternode.conf** — when + running a hot wallet with `-masternode=1` on a host whose wallet held + multiple collaterals, the local masternode could bind to an arbitrary + collateral, frequently one belonging to a declared remote masternode. + Two daemons then signed votes with one collateral identity, producing + ban storms across the fleet. The collateral selection now correctly + honours `masternode.conf`. + +### Collateral lock semantics + +- **Remote masternode start now auto-locks the collateral** — local + masternodes always did this, but the remote-Register code path + skipped the lock. Now both paths protect the collateral identically. + Existing remote-MN setups will pick up the lock the next time the + controller wallet ReRegisters. +- **Stopping a masternode no longer auto-unlocks the collateral** — + locks set on a masternode's collateral UTXO are user data and now + persist across stop/start. To spend a previously-locked collateral, + use the new Locked Outputs dialog (Tools → Locked Outputs...), or the + Lock/Unlock context menu in the Masternodes tab. + +### Peer reliability and ban-storm prevention + +- **Fixed: `dseg` re-ask penalty** — a peer re-requesting the masternode + list inside the rate-limit window was scored `Misbehaving(34)` — a + third of a ban — for what is normal behaviour after a restart or + dropped connection. Three such re-asks reached the ban threshold. + Duplicate requests are now rate-limited and ignored without penalty. +- **Fixed: `dseg` requester-side retry** — `DsegUpdate` used a 3-hour + cool-off unconditionally, so a lost request left the node with no + masternode list for three hours. The retry interval now adapts to + list state: 3-minute retries while empty, full 3 hours once populated. + This is the most directly visible fix for a real chain phenomenon: + during long chain stalls on prior versions, the stale masternode + list could mean no masternode could be located at payout time, and + the payment fell through to the devops address via the + consensus-defined fallback. The adaptive retry restores the + masternode list within minutes after a stall, restoring normal + payouts immediately. +- **Fixed: invalid-signature `mnvote` ban-storm** — an `mnvote` with + a `CheckSignature` failure scored `Misbehaving(100)` (instant ban). + Observed on testnet as ban storms where honest relayers were being + banned for forwarding votes they could not have known were + unverifiable. The relay path now blocks junk-signature votes from + propagating; the residual misbehaviour score is lowered to a + rate-limiting `5`. +- **Fixed: masternode-payee strict-check firing pre-activation + (CW12)** — v2.0.0.8's earlier "Spec C D2" change unconditionally + enabled a strict masternode-payee validation check that + v2.0.0.6 had effectively never run (the v2.0.0.6 gate flag + `fMnAdvRelay` defaulted to false and was never set true in + production). Spec C D2 was correct in principle ("consensus + enforcement should not ship behind an undocumented flag") but + the implementation missed adding an explicit activation-height + gate, leaving the strict check firing in the warmup-elapsed + window regardless of whether voted-consensus enforcement was + active. Combined with normal masternode-broadcast propagation + lag, this produced cascading peer bans: observed on testnet + block 206 where **5 of 8 nodes** banned the LAN gateway IP + (via NAT hairpin) and stalled for hours. The fix gates the + strict weak check on `GetEffectiveVotedConsensusActivationHeight()` + — the same height at which voted-consensus enforcement + activates. Pre-spork on mainnet (default floor `INT_MAX`), + the check never fires — matching v2.0.0.6 effective mainnet + behaviour precisely. Post-spork the check engages in + lockstep with voted-consensus enforcement. +- **Fixed: NAT-hairpin address pollution** — inbound port-forwarded + connections arrive with their source address rewritten to the LAN + gateway, and that address was being entered into `addrman` and + gossiped network-wide. The address admission is now gated on + `addrFrom.IsRoutable()`; the connection itself still flows, only the + bogus address is prevented from propagating. +- **Fixed: dsee processing during initial block download** — a node + still syncing was scoring `Misbehaving(20)` on valid dsee messages + whose collateral confirmation depth hadn't yet been reached locally. + Now gated on `!IsInitialBlockDownload()`. +- **Fixed: peer handshake gap on queue catch-up** — a v2.0.0.8 node + that connected to peers received only future broadcasts, not the + peer's in-flight queue inventory. A freshly-restarted or + newly-connected node would therefore start with an empty queue map + for already-in-flight heights and defer block production until new + schedules arrived. The handshake now includes a `getmnqueues` request + so peers respond with their current queue inventory. + +### Equivocation handling + +- **Fixed: equivocation auto-clear was dead code in steady state** — + the documented Path A recovery (cleared by `OnFreshDsee` on a + legitimate later broadcast) was wired only into the new-MN + registration path. Routine dsee re-broadcast and dseep heartbeats + never invoked it. The Path A wiring is now correctly invoked from + all three call sites: new-MN add, dsee known-MN update, and dseep + heartbeat. +- **Fixed: equivocation false-positive on legitimate re-broadcast** — + the equivocation detection branch was treating any second queue at + the same height with a different hash as malicious, even though + M1Q spec S10.1 explicitly permits legitimate re-broadcast after a + brief chain reorg with a refreshed timestamp or schedule. Observed + on testnet 2026-06-02 as all 7 MNs being simultaneously flagged + during a normal 4-second 4305→4306 advance with no local disconnect. + Detection is replaced with **newer-wins replacement** based on + `nTimeSigned`: a later legitimate broadcast replaces an earlier one + rather than marking the broadcaster as a malicious equivocator. + +--- + +## 🪙 Masternode Collateral Tools + +- **2,000,000 XDN incoming-collateral popup** — when an incoming + transaction lands a UTXO of exactly the masternode collateral amount, + you'll be prompted whether to lock it. Three choices: lock now, ask + again next time, or never ask for this wallet. +- **Lock column in My Master Nodes table** — at-a-glance visibility of + every configured masternode's collateral lock state, with + closed-padlock icon and "Locked"/"Unlocked" text. +- **Lock / Unlock context menu** — right-click any row in the My Master + Nodes table to lock or unlock that masternode's collateral. +- **NEW: Locked Outputs dialog** — `Tools → Locked Outputs...` opens a + comprehensive view of every locked output in the wallet. Each row + shows: lock status, address, label, amount, type classification + (Masternode: `` / 2M XDN not in masternode.conf / Other locked + output), and full TXID:vout. Click the lock cell or double-click any + cell to unlock — with a tier-appropriate confirmation dialog. + Right-click for Copy txid / Copy address / Copy amount. Watch-only + outputs are filtered out. +- **Standard selection model in My Master Nodes table** — click selects + (replacing previous selection), Ctrl-click adds, Shift-click + range-selects. Replaces the older "every click toggles" + multi-selection that required explicit unselect. + +--- + +## ⛏️ Proof-of-Stake Reliability + +- **Fixed: rare staker stalls under load (Class B lock-order deadlock)** + — under specific multi-thread timing, the staking thread could + deadlock with peer message processing across `cs_main` and + `voteTracker.cs`. Diagnosed via gdb on a symboled debug build after + three observed wedges at ~18-hour intervals. The vote-tracker's + consensus-read functions now self-protect with `LOCK2(cs_main, cs)` + so the canonical lock-acquisition order (`cs_main` before + `voteTracker.cs`) holds in every code path. Confirmed clean through + multi-day soak after the fix. +- **Fixed: PoS coinstake input stale spent-flag** — the consumed kernel + input was being marked spent only via the catch-all per-block + `FixSpentCoins` reconciliation, which left a window where the wallet + could attempt to re-stake the same UTXO. The mark is now targeted + directly at the kernel input in the coinstake construction path, + eliminating the reliance on band-aid reconciliation. +- **Fixed: payee streak / chain stall at activation crossing** — a + pre-activation last-paid clamp was collapsing multiple masternodes to + the same rank key, causing the smallest-vin tiebreak to freeze + selection on one MN for the entire vote-lookahead window. The clamp + is removed; the chain-derived ranking is correct in every epoch + without normalisation. Confirmed at the testnet activation crossing + with a clean rotation. +- **Fixed: post-activation payee streak artifact (M1Q queue redesign)** + — the per-height vote path ranked on `mapLastPaidHeight`, which is + written only when a block connects, while the vote/selection for a + height runs lookahead blocks earlier. The selector's last-paid view + was therefore lookahead-blocks behind the height it selected for, so + a masternode could be re-selected for every height in that lag window + until its own payment connected. Resolved by the **M1Q queue redesign** + (forward-simulated ordered queues) which removes the lag + structurally. +- **Fixed: staker mint-retry storm on too-early blocks** — + `Velocity()` enforces a minimum block spacing of 45 seconds; a + too-early PoS block is rejected. The staker thread was discarding + the rejection result and retrying every 500 ms, producing a CPU/log + storm until wall-clock crossed the threshold. The staker now backs + off until the spacing is satisfied. +- **Fixed: post-restart staking visibility** — the staking icon + previously showed "not staking" until the first successful coinstake + search interval elapsed, often appearing inactive for several + minutes after a healthy startup. The icon now reflects the actual + thread state: a clock during warm-up, the hammer once actively + searching, the inactive icon when staking is genuinely off. +- **Fixed: staking icon stuck on "warming up" for healthy stakers** — + a counter the icon previously read was only updated when the kernel + search exited *without* finding a block, so on a wallet that found + blocks successfully, the counter stayed at zero and the icon + displayed the "warming up" clock indefinitely even while blocks were + being produced. The icon now reads directly from the staking + thread's heartbeat via a proper state machine. +- **Fixed: staking icon showed "no mature coins" while actively + staking** — on a frequent-staking wallet where all stakeable balance + was permanently inside the maturity window, `nWeight` reported 0 and + the icon showed the "no mature coins" state despite the wallet + successfully staking every few minutes. The icon now distinguishes + "actively staking, coins maturing" (clock) from "no stakeable + balance" (none). +- **Improved: expected-time-between-blocks tooltip** — replaces the + previous nonsense values (one observation: "1763 days 13 hours" on + a healthy testnet staker) with a correct formula based on your + wallet weight and the network's total stake weight. +- **Fixed: PoS staker did not resume after M1Q switch-over** — after + the queue-based consensus replaced the per-height vote path, the + staker's readiness gate still probed the old (now-unpopulated) + per-height vote map and logged "deferring … vote tracker not ready" + indefinitely. The gate now probes the queue path the validator + actually consults. + +--- + +## 🌐 Testnet — Established and Operational + +**New in v2.0.0.8.** Prior versions of DigitalNote did not have a +functional testnet; the v2.0.0.8 voted-consensus feature genuinely +could not be validated without one, and bringing the testnet up was +substantial work in its own right. + +- **Testnet rebuilt from genesis** — an earlier testnet attempt had + accumulated forked PoS state, mutually-banned nodes, and chain + history that could not be resynced past a stalled block (caused by + the now-fixed VRX difficulty bug, see Network section). The fleet + was wiped to genesis on a binary containing the determinism fixes + and the voted-consensus work; a genesis-clean chain on the fixed + binary is correct by construction. +- **Testnet parameters** — P2P port 28092, RPC port 28094, selected + via the `-testnet` switch only. Genesis is 18 Jan 2019 with no + premine (`SetEmpty()` coinbase). Masternode and devops payments + are active from block 1. Voted-consensus activation floor is + height 2000 (testnet only); a long pre-activation window allows + vote propagation testing with zero fork risk. +- **Topology** — 6 masternodes + 1 PoS staker, with a permanent + public explorer + seed node at `testnet.xdn-explorer.com` (added + to the testnet `vSeeds` and the generated default testnet conf). +- **Bug fixes uncovered during testnet construction** — bringing up + a real multi-node network surfaced an entire class of + configuration-driven bugs that single-node testing could not have + exposed: same-IP multi-MN connection rejection (`OpenNetworkConnection` + was using an IP-only `FindNode` check that prevented all but one + MN on a shared IP from connecting); NAT-hairpin address pollution; + duplicate-masternode-identity faults from collateral selection + ignoring `masternode.conf`; ban storms from over-aggressive scoring + on routine peer behaviour; consensus enforcement gated behind a + long-abandoned config flag (`-mnadvrelay`, defaulting to false, so + enforcement could never engage). All such bugs are fixed in this + release. +- **SPORK_14/15 activation rehearsal** — staged broadcast and + propagation of SPORK_14 across the entire fleet, followed by a + full controlled activation crossing at height 1837 using + `SPORK_15` to bring the activation height forward from the 2000 + floor. The crossing succeeded: block 1837 (PoW) and block 1838 + (PoS) both accepted with 7/7 voter consensus, with the + clamp-free payee selector rotating cleanly across the boundary. + +--- + +## 🔐 BIP39 Recovery Phrase + +- **24-word recovery phrase** generated automatically when encrypting + a new wallet — shown once immediately after encryption, never shown + again without password verification. +- **Recovery phrase unlocks your wallet** — both your password AND + your 24-word recovery phrase can be used to unlock the wallet + (wallet.dat must be present). +- **Existing wallet upgrade** — users with wallets encrypted in + v2.0.0.6 or earlier can upgrade via `Settings → Recovery Phrase`. + A one-time process that keeps your wallet encrypted throughout. If + you decline, the prompt won't return for that wallet — you can + still upgrade manually any time. +- **Password required to reveal phrase** — `Settings → Recovery + Phrase` requires your password before displaying the 24 words. +- **Recovery phrase stable across password changes** — once your + wallet has been BIP39-upgraded, the recovery phrase you wrote down + stays valid even after you change your password. +- **`getrecoveryphrase` RPC command** — wallet must be unlocked + before calling; returns your 24-word recovery phrase. + +--- + +## 💰 Balance and Wallet Correctness + +### Balance display + +- **Fixed: balance could appear lower than the true balance after + launching the wallet** — on wallets with a large number of + transactions, the balance shown immediately after startup could be + less than the real spendable balance. The discrepancy persisted for + the rest of the session until the wallet was restarted with + `-staking=0` or unlocked. Your coins were never at risk; the bug + was in the displayed total only. +- **Fixed: imported watch-only addresses showed inflated credit until + restart** — live-added transactions during a rescan now correctly + populate the spend tracking. +- **Fixed: watch-only stake leaked into Spendable Stake column** — + wallets with watch-only addresses no longer have their watch-only + stake totals counted as spendable. +- **Fixed: P2PK outputs invisible to watch-only tracking** — stake + rewards paid back via P2PK to imported watch-only addresses are now + correctly tracked. +- **Fixed: rescan-discovered historical transactions timestamped at + the wrong time** — old transactions discovered by a rescan are now + stamped with their actual block time rather than being clamped to + the most recent existing transaction's time. + +### Spent-tracking correctness (new in v2.0.0.8) + +- **Fixed: wallet balance over-reported after observing sends or + stakes via gossip** — when a wallet observed a transaction + involving its own keys via P2P gossip (rather than initiating it + locally), the consumed inputs remained flagged as spendable in the + wallet's per-transaction `vfSpent` tracking. The reported balance + would over-state the true available balance by the value of the + consumed inputs. Users could observe this after running + `repairwallet`, which would "mysteriously" reduce their reported + balance. The wallet's balance and coin-selection readers now + consult the automatic global spend-tracking map (`mmTxSpends`), + which is populated as transactions are added to the wallet + regardless of source. The displayed balance now reflects true + on-chain state automatically, without periodic `repairwallet` + invocations. +- **Fixed: PoS coinstake input stale spent-flag** — see Proof-of-Stake + Reliability above. The writer-side companion to the reader fix. +- **Improved reorg robustness** — the new spent-tracking reader is + reorg-safe: outputs whose consuming transaction was orphaned during + a reorg correctly drop back to unspent without manual repair. +- **Spendable and watch-only balance now share the same spent-tracking + semantics** — the watch-only readers had already migrated to the + `mmTxSpends`-based reader in earlier work; the spendable readers + catch up in this release. Both balance lines now derive from the + same automatic, reorg-safe source of truth, eliminating a + long-standing asymmetry where watch-only balance was correct while + spendable balance could drift on gossip-observed activity. This was + audited against the v2.0.0.7 watch-only fixes (P2PK IsMine fallback, + spendable/watch-only stake separation, RemoveWatchOnly three-phase + prune, AvailableCoinsForStaking lock-coin semantics) and confirmed + non-regressing. + +### Coin selection + +- **Fixed: 2M payments excluded the entire transaction from staking** + — only the specific output is excluded now (and only if the user + has explicitly locked it), not all the change outputs alongside it. + +### Unlock flow + +- **Fixed: `CWallet::Unlock()` now tries all master keys** — changed + from failing on first key mismatch to iterating all keys, enabling + both password and recovery phrase to unlock the wallet. + +--- + +## 🛠️ Rebuild Wallet (Maintenance) + +- **New: `Tools → Compact Wallet`** — rebuilds your wallet.dat file + to reclaim free pages and rebuild the internal structure. The + result is usually a smaller and faster wallet, especially on + long-running wallets that have accumulated many transactions. +- **What it does:** dumps every record in your wallet, validates the + dump with a checksum, builds a fresh wallet, swaps it in, and + rescans. +- **What it preserves:** all of it — private keys, addresses, + balances, transaction history, watch-only addresses, locked + outputs, the BIP39 mnemonic, address book entries. Encrypted + wallets stay encrypted; you don't need to enter your password. +- **Safety:** before the swap, your original wallet is renamed to + `wallet.dat.bak` in your data directory. If anything goes wrong, + your old wallet is right there to fall back to. We recommend taking + an independent backup as well before you start, just in case. +- **What to expect:** the wallet shuts down and restarts + automatically. The rebuild itself can take minutes to hours + depending on wallet size; the wallet is unusable during this time + and shows a maintenance-mode splash screen. After the rebuild, a + rescan runs to refresh the transaction cache. When the wallet + finally opens normally, a one-shot dialog tells you the outcome. +- **For advanced users:** the same operation is available from the + command line via `-rebuildwallet`, and the underlying dump and + create primitives are exposed as hidden RPCs (`dumprawwallet`, + `createfromdumpfile`) for testing and manual recovery workflows. + +--- + +## 🌐 Network and Synchronisation + +- **Fixed: difficulty-recovery curve never engaged in v2.0.0.6** — + v2.0.0.6's `VRX_ThreadCurve` computed `difTime = blkTime - cntTime` + where both inputs resolved to the same block on PoW retarget, so + `difTime` was always zero and the stall-recovery loop never fired. + This was the cause of long chain pauses on mainnet where mining + difficulty stayed high through stalls instead of dropping + progressively. v2.0.0.8 fixes the recovery curve so it engages + correctly during real stalls, allowing the chain to auto-recover + from periods where mining capacity couldn't keep up. +- **Fixed: VRX retarget became non-deterministic during resync** — + the curve-engagement fix between v2.0.0.6 and v2.0.0.8 used the + node's wall clock (`GetAdjustedTime()`) as the curve's stall-time + input. This worked at mining time (miner's wall clock ≈ block + timestamp) but during a from-genesis resync, the validator's wall + clock is years ahead of the block being validated, the recovery + loop engaged hard, and the validator computed a completely + different `nBits` than the block carried. v2.0.0.8 makes the + validator's retarget a deterministic function of committed block + time, so re-validation reproduces the original computation + exactly. +- **Extended historical `nBits` exception list** — because v2.0.0.6's + broken curve and v2.0.0.8's working curve produce different `nBits` + values for blocks that followed long stalls, mainnet history + contains around 30 blocks whose committed `nBits` v2.0.0.8's + correct computation disagrees with. These blocks were valid under + v2.0.0.6's rules at the time they were mined; they are accepted by + v2.0.0.8 via an extended height-exception list in `AcceptBlock`. + The strict `nBits` check remains fully active for every other + block, including all blocks mined post-v2.0.0.8 (which produce + determinism-by-construction nBits values that always pass). The + exception list is one-time archaeology, never grows after release. +- **Mining-side same-timestamp guarantee** — v2.0.0.8 finalises the + block's `nTime` first, then computes `nBits` using that committed + timestamp. Pre-fix, the miner computed `nBits` from + `GetAdjustedTime()` early in `CreateNewBlock` while the validator + used `pblock->nTime`; a ~3,600-second hourly-boundary window + existed where the two could fall on opposite sides of a recovery + step and produce different difficulty values, causing self-rejection + on submission. The fix eliminates that residual risk by using the + block's own committed time on both sides. After v2.0.0.8, miner + and validator agree on `nBits` by construction. +- **New: devops address rotation — activates at block 1,400,000** — + the consensus-defined devops payment recipient rotates to a fresh + wallet at mainnet block 1,400,000 (estimated ~early September 2027 + at current block rate). The previous address has accumulated four + years of transaction history and the wallet file has grown to + approximately 720MB on disk even after repeated Compact Wallet + runs. The new address (`dGoFPie9QZmQ1Ty1beqSHytxNruehpGtGa`) is a + fresh wallet with no transaction history, restoring fast wallet + operations. The rotation is automatic at the activation block — no + operator action required. Pool operators and exchanges who pay or + receive directly from the devops address should update their + references; everyone else's blocks include the correct address + automatically via the consensus rule. On testnet the same rotation + fires at block 100 to allow live validation of the mechanism within + the first hour of testnet operation. +- **New: strict devops-address check re-enabled, height-gated** — + the validator's strict comparison of the block's devops payment + recipient against the canonical expected address (commented out + since pre-v2.0.0.6 to avoid breaking resync past historical + transition irregularities) is restored in v2.0.0.8 and gated to + activate at the rotation block. Pre-rotation chain history + (everything before block 1,400,000 on mainnet) continues to + validate leniently — log-only on any mismatch — preserving full + from-genesis resync compatibility including the v1.0.1.5 + transition irregularities (mid-2019) and the v1.0.4.2 + chain-correction (block 403117, mid-2021). Post-rotation + (1,400,000 and beyond on mainnet, 100 and beyond on testnet) the + strict check rejects any block where the devops recipient + disagrees with the consensus-defined expected address. This + closes the misdirected-payment vulnerability that would otherwise + allow a producer to redirect devops funds without consequence. +- **New: producer/validator off-by-one in the devops ladder, fixed** — + the devops-recipient lookup function is refactored to a pure + height-based form (`getDevelopersAdressForHeight(int, int64_t)`) + with the existing `CBlockIndex*`-based form as a backward-compatible + wrapper. All producer-side callers (in `miner.cpp`, `cwallet.cpp`, + and `rpcmining.cpp`) migrate to ask the ladder about the height of + the block being mined, not the chain tip. Pre-fix, the producer + asked about `pindexBest` (= N-1) when constructing block N, while + the validator asked about the block at N — so at rotation + boundaries they disagreed by one block. Latent in mainnet history + for v1.0.1.5 (block 65020) and v1.0.4.2 (block 403117) because + the strict check was commented out; after CW9, both sides ask + about the same block by construction. +- **Fixed: wallet banning peers on startup** — block validation now + correctly handles mixed-version networks during the transition + period; peers running older versions are no longer incorrectly + banned. +- **Fixed: startup verification rolling back the chain** — after the + enforcement-gate removal made the masternode-payee check enforce, + a node restarting could roll its chain back hundreds of blocks + because the verify pass re-ran the check against an empty + runtime masternode list. The original v2.0.0.6 guard + (`hashPrevBlock == hashBestChain`, meaning "this block extends + the current tip") is restored, so the check runs only for genuinely + live tip blocks, not historical blocks being re-verified at startup. + +--- + +## 🖥️ Wallet GUI + +### Menu organisation and theme + +- **New Tools menu** — maintenance and system actions consolidated + under a dedicated Tools menu: Show Backups; Check Wallet, Repair + Wallet, Compact Wallet; Locked Outputs; Debug Window, Open Data + Directory, Edit Config File, Edit Config Ext File. The last four + moved from Help (which now holds only About / About Qt — clean + reference-only). Settings holds security state and preferences only + (Encrypt Wallet, Change Passphrase, Unlock variants, Lock Wallet, + Recovery Phrase, Options). +- **Dark theme** — toggle via `Settings → Dark Theme`; applies to all + windows and dialogs. +- **In-app DigitalNote.conf editor** — a new menu entry allows editing + the wallet's configuration file without leaving the application. + Changes are written safely and the wallet warns about pending + restart requirements. + +### Splash and startup + +- **New splash screen** — circle logo with transparent background and + centred loading text. +- **Maintenance Mode splash** — distinct chromed splash for `-rescan`, + `-reindex`, `-rebuildwallet`, and other long-running operations, so + it's clear the wallet is doing maintenance rather than starting + normally. Stays on top so it isn't buried under other windows + during long runs; minimise to tray and restore via the tray icon + both work. +- **Fixed: rescan splash appeared frozen** — the splash now shows + progress as `Rescanning... block N / M` updating every 5000 blocks, + including the post-rebuild rescan triggered by Compact Wallet. +- **New app icons** — updated circle logo icons across all sizes and + the Windows `.ico` file. Includes a 24×24 entry to satisfy Windows + 11's tray expectation (was previously a 32×32-only logged warning). + +### Password and unlock + +- **Password generator** — `⚙ Generate strong password` button in the + encrypt wallet dialog creates a random 20-character password with + one-click copy. +- **"Forgot password?" link** — the unlock dialog now has a link to + unlock via recovery phrase. +- **Staking checkbox hidden** — the "for staking only" checkbox is + hidden by default in standard unlock mode. + +### Status bar and tooltips + +- **MAINNET indicator** — network type shown in the status bar with + tooltip. +- **Build date and version in About box** — the build script now + embeds the build date into the version string, so `getinfo`, the + GUI title bar, and the About box accurately identify which build + is running. Replaces the long-broken behaviour of self-reporting + as `v1.0.3.5` (an ancient git tag) for the entire v2.0.0.x line. + +### Transaction display + +- **Fixed: locally-mined PoW coinbases now appear in the transaction + list immediately** — previously, a freshly-mined PoW block's + coinbase would only appear in the GUI's Recent Transactions and + Transactions tab when the *next* block arrived (a one-block UI + lag). The cause was a static handler that intentionally deferred + the notification by one block via `hashPrevBestCoinBase`. The + block's `IsInMainChain()` check at AddToWallet-time returned false + (chain links were not yet finalised), so the GUI filtered the row + out. Solo PoW miners now see their wins instantly. PoS stakers + were never affected (coinstake is not subject to the same filter). +- **Fixed: double-clicking a transaction in the Transactions tab now + opens the transaction details dialog** — previously a no-op; + right-click → "Show transaction details" was the only working + path. +- **Fixed: transaction-detail "Transaction ID" suffix was always + `-000`** — the suffix was being derived from a display-row sort + ordinal rather than an input or output index. The detail line now + shows the clean transaction hash. +- **Bounded notification batching during import** — during initial + block download and rescan operations, individual transaction + notifications could pile up. They are now batched into a single + summary notification per batch (showing the count and kind). + +### Masternode page + +- **Masternodes page default tab corrected** — the page now opens on + the "DigitalNote Network" tab by default (was opening on "My + Masternodes"). + +### Debug console + +- **Debug console input field is disabled with an elapsed-time + indicator while a command is in flight**, so you can tell when the + wallet is busy versus stuck. +- **Windows paths typed without quotes** (e.g. `dumpwallet + C:\temp\test.dmp`) now work correctly; previously the parser + silently mangled backslashes. +- **Fixed: `-debug=all` and `-debug=1` silently did nothing (CW14).** + Both forms looked like intuitive ways to enable wildcard logging + but were treated as unknown category names (`fDebug` was set true + but no `LogPrint("category", ...)` calls matched). The bare + `-debug` form was the only wildcard. Now all three (`-debug`, + `-debug=all`, `-debug=1`) enable wildcard logging identically. + Help text also updated to document the disable forms (`-debug=0`, + `-nodebug`). Comprehensive operator reference in + `debug-logging-guide.md` covers all 21 categories with + diagnostic-scenario recipes and log-volume guidance. + +### Removing watch-only addresses + +- **Fixed: removing a watch-only address left "(n/a)" ghost rows** — + orphaned transactions are now pruned, with a progress bar for the + (potentially slow) operation. + +### Misc visual polish + +- **Fixed: balance labels could clip the trailing "N" in "XDN"** — + minimum width set on all balance labels (Available, Stake, Pending, + Total, plus watch-only column). +- **Fixed: copyright year in About dialog** — updated to 2018-2026. +- **Fixed: Coin Control lock icon nearly invisible against light + theme** — was white-on-transparent (designed for the dark-coloured + status bar); now black-on-transparent for the default theme. Status + bar lock icon unchanged. +- **Various Qt signal/slot warnings cleared** from the debug log on + startup. + +--- + +## 🔧 Build & Release + +- **GitHub Actions CI/CD** — automated builds for Windows x64, Linux + x64, Linux ARM64, macOS Intel, and macOS Apple Silicon. +- **Automated releases** — pushing a version tag (`v2.0.0.8`) builds + all platforms and publishes a GitHub Release with binaries and + SHA256 checksums automatically. +- **Build version stamping** — version string is now controlled + entirely by source files (`clientversion.h`), not derived from + potentially-stale git tags. Build date falls back to the compiler's + `__DATE__` / `__TIME__` so the date is always accurate to the build. +- **BIP39 library merged inline** — no longer an external submodule; + compiled directly into the wallet binary. The optional `USE_BIP39=0` + build flag has been retired since BIP39 is now load-bearing for + the wallet UX (recovery phrase, "forgot password" recovery). +- **New asset naming convention** for release downloads: + `---.`. For v2.0.0.8 the assets are: + - `DigitalNote-qt-2.0.0.8-win-x64.exe` + - `DigitalNote-qt-2.0.0.8-linux-x64` + - `DigitalNote-qt-2.0.0.8-linux-arm64` + - `DigitalNote-qt-2.0.0.8-macos-x64.dmg` (Intel) + - `DigitalNote-qt-2.0.0.8-macos-arm64.dmg` (Apple Silicon) + - `DigitalNoted-2.0.0.8-win-x64.exe` + - `DigitalNoted-2.0.0.8-linux-x64` + - `DigitalNoted-2.0.0.8-linux-arm64` +- **`linux-x64-compat` build variant** — for older Linux + distributions. Standard `linux-x64` builds against Ubuntu 24.04+ + (glibc 2.39+, libstdc++ 14+); the compat variant builds against an + older glibc baseline (2.31+, covering Ubuntu 20.04, Debian 11, + RHEL 9) and statically links libstdc++. +- **32-bit builds dropped** — previous releases shipped `linux.i386` + and `win32` variants; these are no longer produced. If you require + a 32-bit build, you'll need to build from source. +- **Apple Silicon native build added** — previous macOS builds were + Intel-only; v2.0.0.8 ships a native arm64 dmg alongside the Intel + one. + +--- + +## ⚠️ Deprecations & Known Issues + +### Deprecated + +- **`-salvagewallet` is deprecated.** It silently drops records on + collision and has been removed from Bitcoin Core, Bitcoin ABC, and + Dash for the same reason. The flag now refuses to run unless + `-iknowsalvagewalletisdangerous` is also passed. For routine + maintenance (compacting a bloated wallet, recovering from minor BDB + issues), use **Compact Wallet** in the Tools menu — it is safe, + preserves all wallet data, and is the recommended path going + forward. For genuine corruption recovery, restore from your + wallet.dat backup; the salvagewallet escape hatch is preserved + only for the rare case where Compact Wallet itself fails on a + wallet too damaged for cursor iteration to traverse. + +### Known minor display behaviour + +- **The masternode list "active" column refreshes on the standard + GUI timer cadence** (~5 seconds). Status changes from incoming + dsee messages may take up to one timer interval to appear. No + functional impact. +- **Coinstake transaction rows in the transaction list are displayed + as a single line** showing the net reward, rather than separate + rows for the staked input and the new output. This is by design + (matches existing PoS wallet conventions); a "show inputs" option + may be added in a future release if users request it. +- **Wallets with very many transactions (tens of thousands or more) + take time to display the transaction list after the splash closes.** + The wallet is functional during this period — RPC calls work, + staking continues — but the GUI window may appear delayed. Compact + Wallet (which dramatically reduces wallet file size on bloated + wallets) typically improves this. A proper fix (incremental load) + is planned for the next release. +- **Toast notification spam during `importwallet`** on the GUI — the + existing batching mechanism doesn't fully suppress notifications + during the import path. Workaround: use Compact Wallet for routine + maintenance instead of `dumpwallet` + `importwallet`. To be + addressed in the next release. + +--- + +## ⚠️ Upgrade Notes + +### Backward compatibility + +- **Chain-compatible** with v2.0.0.6 until the voted consensus + activation height is reached. You can run mixed-version networks + safely up to that point. +- **Network protocol** is bumped. v2.0.0.8 nodes accept connections + from v2.0.0.6 clients and function normally. After voted-consensus + activation, only v2.0.0.8 (or later) masternodes contribute to the + consensus vote — older clients can still connect and sync but + their votes are not counted. +- **No mandatory upgrade** is forced by this release. The voted + consensus activation is a separate spork-controlled event. +- **Recovery phrase** is only available for wallets encrypted with + v2.0.0.8 or later. Users with older wallets should go to + `Settings → Recovery Phrase` immediately after upgrading to + complete the one-time upgrade process. + +### Recommended upgrade order + +For masternode operators with multiple roles in the network: + +1. **Masternodes first** — they generate the queue broadcasts that + the network will rely on post-activation. +2. **Mining pools second**. +3. **Stakers third**. +4. **Full nodes last**. + +### For regular wallet users + +Update at your convenience. There's no impact on send/receive, +balance display, or wallet file compatibility. The voted consensus +feature affects only masternode payment selection, not user +transactions. + +### For pool / exchange operators + +Update at your convenience. Block validation and reorg handling +follow the soft-activation pattern described above — there's no +risk of a sudden chain split at activation, even if some pool nodes +upgrade later than others. The recommended approach is the same as +for any other upgrade: test in your staging environment first, then +roll out to production at a quiet window. + +--- + +## 🔍 MISC + +Smaller items, polish work, and items worth noting that don't fit +the categories above. + +### Polish and operational logging + +- **Per-block log noise reduced** — steady-state masternode/devops + payee verification chatter, "matches voted consensus" lines, and + the init-progress spray during chain load are now gated behind + debug categories. A normal (debug-off) node now logs around two + lines per block plus loud errors; `-debug=1` restores everything + for soak nodes that need full visibility. `--help` documents the + available `-debug` categories: `masternode`, `mnengine`, + `instantx`, `smsg`, `webwallet`, `retarget`, `init`. +- **Fixed: ~1378 "coinstake as individual tx" errors per launch** + spamming the debug log — wallet startup now correctly excludes + coinstakes from mempool reaccept (these errors had no functional + impact but made the log very noisy). + +### Internal modernisation + +- **Legacy per-height vote message path removed.** The + `mnvote`/`getmnvotes` P2P messages that preceded the M1Q + queue-based path were dormant in the source tree but unused. + Around 500 lines of dead code and two source files were removed, + reducing binary size and eliminating a class of potential + confusion for future contributors. +- **Lock-ordering throughout the masternode-payment validation + path** has been audited and standardised so the same + lock-acquisition pattern (`cs_main` before `voteTracker.cs`) + holds in every code path that uses both locks, both directly and + via callees. + +### Verified — not bugs + +- **Permissive `payee == empty` pass in `CheckBlock`** — when the + voted-payee getter returns false or an empty payee (e.g. during + a pre-activation window or post-activation consensus gap), + `CheckBlock` accepts the block's payee as-is. This is the intended + permissive soft-fork fallback — it prevents a consensus gap from + stalling the chain. + +### Acknowledgements + +Voted consensus design and validation: thanks to all testnet +masternode operators who ran extended soak sessions and reported +edge cases throughout the v2.0.0.8 cycle. The multi-day +parallel-staker observation runs were essential for catching the +late-cycle lock-order issues, the equivocation edge cases, and the +balance-tracking interaction that this release closes out. + +--- + +## 🔗 Resources + +- **Website:** https://digitalnote.org/ +- **Repository:** https://github.com/DigitalNoteXDN/DigitalNote-2 +- **Block explorer:** https://xdn-explorer.com/ +- **Testnet explorer:** https://testnet.xdn-explorer.com + diff --git a/docs/release-notes/v2.0.0.7.md b/docs/release-notes/v2.0.0.7.md new file mode 100644 index 00000000..a9747ffa --- /dev/null +++ b/docs/release-notes/v2.0.0.7.md @@ -0,0 +1,112 @@ +# DigitalNote XDN v2.0.0.7 Release Notes + +## 🔐 BIP39 Recovery Phrase + +- **24-word recovery phrase** generated automatically when encrypting a new wallet — shown once immediately after encryption, never shown again without password verification +- **Recovery phrase unlocks your wallet** — both your password AND your 24-word recovery phrase can be used to unlock the wallet (wallet.dat must be present) +- **Existing wallet upgrade** — users with wallets encrypted in earlier versions can upgrade via `Settings → Recovery Phrase`. A one-time process that keeps your wallet encrypted throughout. If you decline, the prompt won't return for that wallet — you can still upgrade manually any time +- **Password required to reveal phrase** — `Settings → Recovery Phrase` requires your password before displaying the 24 words +- **`getrecoveryphrase` RPC command** — wallet must be unlocked before calling; returns your 24-word recovery phrase + +## 💰 Balance Display Fix + +- **Fixed: balance could appear lower than the true balance after launching the wallet** — on wallets with a large number of transactions, the balance shown immediately after startup could be less than the real spendable balance. The discrepancy persisted for the rest of the session until the wallet was restarted with `-staking=0` or unlocked. Your coins were never at risk; the bug was in the displayed total only +- The fix also ensures balance caches are recomputed correctly after unlocking an encrypted wallet + +## 🛠️ Rebuild Wallet (Maintenance) + +- **New: `Tools → Compact Wallet`** — rebuilds your wallet.dat file to reclaim free pages and rebuild the internal structure. The result is usually a smaller and faster wallet, especially on long-running wallets that have accumulated many transactions +- **What it does:** dumps every record in your wallet, validates the dump with a checksum, builds a fresh wallet, swaps it in, and rescans +- **What it preserves:** all of it — private keys, addresses, balances, transaction history, watch-only addresses, locked outputs, the BIP39 mnemonic, address book entries. Encrypted wallets stay encrypted; you don't need to enter your password +- **Safety:** before the swap, your original wallet is renamed to `wallet.dat.bak` in your data directory. If anything goes wrong, your old wallet is right there to fall back to. We recommend taking an independent backup as well before you start, just in case +- **What to expect:** the wallet shuts down and restarts automatically. The rebuild itself can take minutes to hours depending on wallet size; the wallet is unusable during this time and shows a maintenance-mode splash screen. After the rebuild, a rescan runs to refresh the transaction cache. When the wallet finally opens normally, a one-shot dialog tells you the outcome +- **For advanced users:** the same operation is available from the command line via `-rebuildwallet`, and the underlying dump and create primitives are exposed as hidden RPCs (`dumprawwallet`, `createfromdumpfile`) for testing and manual recovery workflows + +## ⛏️ Masternode Fixes + +- **Fixed: `getblocktemplate` always returned the same masternode winner** — the old code used the genesis block hash (height 0) in its score calculation, causing the same masternode to win every block indefinitely +- **Fixed: all masternodes displayed the same "last paid" time** — a copy constructor bug overwrote the real last-paid time with the current time on every copy +- **Fixed: masternodes stopping when collateral wallet version differs from remote daemon** — the version check was too strict; masternodes now activate correctly across minor version differences between wallet and daemon +- **Fixed: masternode start failing with "could not allocate vin" when collateral is locked** — the candidate-selection path no longer filters out locked outputs. Locked collaterals are normal (they're the wallet's own protective signal that an MN is in active use), and the start path now correctly recognises them as valid. This bug surfaced post-restart on configurations where the user had manually locked collaterals before sending a "send all available" +- **Remote masternode start now auto-locks the collateral** — local masternodes always did this, but the remote-Register code path skipped the lock. Now both paths protect the collateral identically. Existing remote-MN setups will pick up the lock the next time the controller wallet ReRegisters (typically within a few minutes of restart) +- **Stopping a masternode no longer auto-unlocks the collateral** — locks set on a masternode's collateral UTXO are user data and now persist across stop/start. To spend a previously-locked collateral, use the new Locked Outputs dialog (Tools → Locked Outputs...), or the Lock/Unlock context menu in the Masternodes tab + +## 🪙 Masternode Collateral Tools + +- **2,000,000 XDN incoming-collateral popup** — when an incoming transaction lands a UTXO of exactly the masternode collateral amount, you'll be prompted whether to lock it. Three choices: lock now, ask again next time, or never ask for this wallet +- **Lock column in My Master Nodes table** — at-a-glance visibility of every configured masternode's collateral lock state, with closed-padlock icon and "Locked"/"Unlocked" text +- **Lock / Unlock context menu** — right-click any row in the My Master Nodes table to lock or unlock that masternode's collateral. Right-clicking implicitly focuses on the row (visible selection narrows to it), so the action acts on what you'd expect +- **NEW: Locked Outputs dialog** — `Tools → Locked Outputs...` opens a comprehensive view of every locked output in the wallet. Each row shows: lock status, address, label, amount, type classification (Masternode: / 2M XDN not in masternode.conf / Other locked output), and full TXID:vout. Click the lock cell or double-click any cell to unlock — with a tier-appropriate confirmation dialog. Right-click for Copy txid / Copy address / Copy amount. Watch-only outputs are filtered out (manage those on the wallet that owns the spend key) +- **Standard selection model in My Master Nodes table** — click selects (replacing previous selection), Ctrl-click adds, Shift-click range-selects. Replaces the older "every click toggles" multi-selection that required explicit unselect. Necessary for sane Start All / Stop All workflows on subsets of masternodes + +## 🐛 Other Bug Fixes + +- **Fixed: double-clicking a transaction in the Transactions tab now opens the transaction details dialog** — previously a no-op; right-click → "Show transaction details" was the only working path +- **Fixed: wallet banning peers on startup** — block validation now correctly handles mixed-version networks during the transition period; peers running older versions are no longer incorrectly banned +- **Fixed: `CWallet::Unlock()` now tries all master keys** — changed from failing on first key mismatch to iterating all keys, enabling both password and recovery phrase to unlock the wallet +- **Fixed: watch-only stake leaked into Spendable Stake column** — wallets with watch-only addresses no longer have their watch-only stake totals counted as spendable +- **Fixed: rescan-discovered historical transactions timestamped at the wrong time** — old transactions discovered by a rescan are now stamped with their actual block time rather than being clamped to the most recent existing transaction's time +- **Fixed: 2M payments excluded the entire transaction from staking** — only the specific output is excluded now (and only if the user has explicitly locked it), not all the change outputs alongside it +- **Fixed: P2PK outputs invisible to watch-only tracking** — stake rewards paid back via P2PK to imported watch-only addresses are now correctly tracked +- **Fixed: imported watch-only addresses showed inflated credit until restart** — live-added transactions during a rescan now correctly populate the spend tracking +- **Fixed: removing a watch-only address left "(n/a)" ghost rows** — orphaned transactions are now pruned, with a progress bar for the (potentially slow) operation +- **Fixed: ~1378 "coinstake as individual tx" errors per launch** spamming the debug log — wallet startup now correctly excludes coinstakes from mempool reaccept (these errors had no functional impact but made the log very noisy) +- **Fixed: rescan splash appeared frozen** — the splash now shows progress as `Rescanning... block N / M` updating every 5000 blocks, including the post-rebuild rescan triggered by Compact Wallet +- **Fixed: balance labels could clip the trailing "N" in "XDN"** — minimum width set on all balance labels (Available, Stake, Pending, Total, plus watch-only column) +- **Fixed: copyright year in About dialog** — updated to 2018-2026 +- **Fixed: Coin Control lock icon nearly invisible against light theme** — was white-on-transparent (designed for the dark-coloured status bar); now black-on-transparent for the default theme. Status bar lock icon unchanged +- **Various Qt signal/slot warnings cleared** from the debug log on startup + +## 🖥️ Wallet GUI + +- **New Tools menu** — maintenance and system actions consolidated under a dedicated Tools menu: Show Backups; Check Wallet, Repair Wallet, Compact Wallet; Locked Outputs; Debug Window, Open Data Directory, Edit Config File, Edit Config Ext File. The last four moved from Help (which now holds only About / About Qt — clean reference-only). Settings holds security state and preferences only (Encrypt Wallet, Change Passphrase, Unlock variants, Lock Wallet, Recovery Phrase, Options) +- **Dark theme** — toggle via `Settings → Dark Theme`; applies to all windows and dialogs +- **New splash screen** — circle logo with transparent background and centred loading text +- **Maintenance Mode splash** — distinct chromed splash for `-rescan`, `-reindex`, `-rebuildwallet`, and other long-running operations, so it's clear the wallet is doing maintenance rather than starting normally. Stays on top so it isn't buried under other windows during long runs; minimise to tray and restore via the tray icon both work +- **New app icons** — updated circle logo icons across all sizes and the Windows `.ico` file. Includes a 24x24 entry to satisfy Windows 11's tray expectation (was previously a 32x32-only logged warning) +- **Password generator** — `⚙ Generate strong password` button in the encrypt wallet dialog creates a random 20-character password with one-click copy +- **"Forgot password?" link** — the unlock dialog now has a link to unlock via recovery phrase +- **MAINNET indicator** — network type shown in the status bar with tooltip +- **Staking checkbox hidden** — the "for staking only" checkbox is hidden by default in standard unlock mode +- **Debug console** — input field is disabled with an elapsed-time indicator while a command is in flight, so you can tell when the wallet is busy versus stuck. Windows paths typed without quotes (e.g. `dumpwallet C:\temp\test.dmp`) now work correctly; previously the parser silently mangled backslashes + +## 🔧 Build & Release + +- **GitHub Actions CI/CD** — automated builds for Windows x64, Linux x64, Linux ARM64, macOS Intel, and macOS Apple Silicon +- **Automated releases** — pushing a version tag (`v2.0.0.7`) builds all platforms and publishes a GitHub Release with binaries and SHA256 checksums automatically +- **BIP39 library merged inline** — no longer an external submodule; compiled directly into the wallet binary +- **New asset naming convention** for release downloads: `---[-compat].`. For v2.0.0.7 the assets are: + - `DigitalNote-qt-2.0.0.7-win-x64.exe` (Windows 10+, x64) + - `DigitalNote-qt-2.0.0.7-linux-x64` (Ubuntu 24.04+ / Debian 13+ / glibc 2.39+) + - `DigitalNote-qt-2.0.0.7-linux-x64-compat` (Ubuntu 20.04+ / Debian 11+ / RHEL 9+ / glibc 2.31+) + - `DigitalNote-qt-2.0.0.7-linux-arm64` (Ubuntu 22.04+ / Debian 12+ / glibc 2.35+, aarch64) + - `DigitalNote-qt-2.0.0.7-macos-x64.dmg` (macOS 12 Monterey+, Intel) + - `DigitalNote-qt-2.0.0.7-macos-arm64.dmg` (macOS 12 Monterey+, Apple Silicon) + - `DigitalNoted-2.0.0.7-win-x64.exe` (Windows 10+, x64) + - `DigitalNoted-2.0.0.7-linux-x64` (Ubuntu 24.04+ / Debian 13+ / glibc 2.39+) + - `DigitalNoted-2.0.0.7-linux-x64-compat` (Ubuntu 20.04+ / Debian 11+ / RHEL 9+ / glibc 2.31+) + - `DigitalNoted-2.0.0.7-linux-arm64` (Ubuntu 22.04+ / Debian 12+ / glibc 2.35+, aarch64) + + **Which Linux x64 build do I want?** If `linux-x64` fails on your system with `GLIBC_2.x not found` or `GLIBCXX_3.4.x not found` errors, switch to the `linux-x64-compat` variant — it's built against an older glibc baseline and statically links libstdc++ to run on a wider range of distributions. +- **32-bit builds dropped.** Previous releases shipped `linux.i386` and `win32` variants; these are no longer produced. If you require a 32-bit build, you'll need to build from source. +- **Apple Silicon native build added.** Previous macOS builds were Intel-only; v2.0.0.7 ships a native arm64 dmg alongside the Intel one. + +## ⚠️ Deprecations & Known Issues + +- **`-salvagewallet` is deprecated.** It silently drops records on collision and has been removed from Bitcoin Core, Bitcoin ABC, and Dash for the same reason. The flag now refuses to run unless `-iknowsalvagewalletisdangerous` is also passed. For routine maintenance (compacting a bloated wallet, recovering from minor BDB issues), use **Compact Wallet** in the Tools menu — it is safe, preserves all wallet data, and is the recommended path going forward. For genuine corruption recovery, restore from your wallet.dat backup; the salvagewallet escape hatch is preserved only for the rare case where Compact Wallet itself fails on a wallet too damaged for cursor iteration to traverse. +- **Wallets with very many transactions (tens of thousands or more) take time to display the transaction list after the splash closes.** The wallet is functional during this period — RPC calls work, staking continues — but the GUI window may appear delayed. Compact Wallet (which dramatically reduces wallet file size on bloated wallets) typically improves this. A proper fix (incremental load) is planned for the next release. +- **Toast notification spam during `importwallet`** on the GUI — the existing batching mechanism doesn't fully suppress notifications during the import path. Workaround: use Compact Wallet for routine maintenance instead of `dumpwallet` + `importwallet`. To be addressed in the next release. + +--- + +## ⚠️ Upgrade Notes + +**Recovery phrase** is only available for wallets encrypted with v2.0.0.7 or later. +Users with older wallets should go to `Settings → Recovery Phrase` immediately after +upgrading to complete the one-time upgrade process. + +**Recommended upgrade order for masternode operators:** +1.

When this does NOT help:

    • " + "
  • If your computer has been compromised by malware, the new phrase " + "may also be observed when it is generated. Clean the machine first.
    • " + "
" + + "

Before continuing:

" + "
    " + "
