DigitalNote XDN v2.0.0.8

DigitalNote XDN v2.0.0.8

DigitalNote XDN v2.0.0.8

Major consolidated release. Mainnet is currently on v2.0.0.6;
v2.0.0.7 was never publicly shipped. This release bundles the entire
accumulated body of fixes built between v2.0.0.6 and v2.0.0.8,
including the new masternode voted-payee consensus headline
feature and the first functional DigitalNote testnet.

Chain-compatible with v2.0.0.6 until voted consensus is activated
by the network spork key. No mandatory upgrade.

---

🗳️ Masternode Voted Consensus (headline feature)

• Per-masternode signed queues of upcoming payees, broadcast and
  tallied by position
• Deterministic forward-simulation produces identical queues on every
  node — position-for-position consensus
• Block validation enforces the agreed payee post-activation
• Activation: floor at INT_MAX (off until further notice);
  SPORK_15 can bring forward, never back
• Soft activation: permissive fallback to legacy rule during
  consensus gaps; no chain-stall risk
• Validated on testnet through SPORK_14/15 rehearsal and a full
  controlled crossing at height 1837 (PoW) / 1838 (PoS) with 7/7
  voter consensus

⛏️ Masternode Fixes

Payment selection and last-paid tracking:

• Fixed getblocktemplate returning the same masternode every block
• Fixed all masternodes showing identical "last paid" times
• Fixed "last paid" not reflecting voted-consensus payments

Masternode start and activation:

• Fixed strict version-equality check preventing cross-version
  activation
• Fixed "could not allocate vin" when collateral is locked
• Fixed local masternode start ignoring masternode.conf (ban-storm
  root cause)

Collateral lock semantics:

• Remote-MN start now auto-locks collateral (matches local-MN)
• Stop-MN no longer auto-unlocks (locks are user data)

Peer reliability and ban-storm prevention:

• Fixed dseg re-ask Misbehaving(34) penalty
• Fixed dseg 3-hour cool-off after lost requests
• Fixed invalid-signature mnvote Misbehaving(100) ban storm
• Fixed masternode-payee strict-check firing pre-activation (CW12:
  gate the v2.0.0.6 fMnAdvRelay-disabled strict check back behind
  voted-consensus activation height, matching v2.0.0.6 effective
  mainnet behaviour byte-for-byte pre-spork)
• Fixed NAT-hairpin address pollution into addrman
• Fixed dsee misbehaviour scoring during IBD
• Fixed missing queue catch-up on peer handshake

Equivocation handling:

• Fixed Path A OnFreshDsee auto-clear being dead code in
  steady-state operation
• Fixed equivocation false-positive on legitimate same-height
  re-broadcast (newer-wins replacement)

🪙 Masternode Collateral Tools

• 2,000,000 XDN incoming-collateral popup
• Lock column in My Master Nodes table
• Lock / Unlock context menu (right-click)
• NEW: Locked Outputs dialog (Tools → Locked Outputs...)
• Standard ExtendedSelection model on the MN list

⛏️ Proof-of-Stake Reliability

• Fixed rare staker stalls (Class B cs_main/voteTracker.cs
  lock-order deadlock — three iterations, gdb-confirmed)
• Fixed PoS coinstake input stale spent-flag (CW4 Fix B)
• Fixed pre-activation last-paid-clamp tie-collapse / payee streak
• Fixed post-activation payee streak via M1Q queue redesign
• Fixed staker mint-retry storm on too-early blocks
  (Velocity back-off)
• Fixed post-restart staking-icon "not staking" delay
• Fixed staking icon stuck on "warming up" for healthy stakers
  (state-machine rewrite)
• Fixed staking icon showing "no mature coins" while actively
  staking (CW6 maturity-window state)
• Fixed nonsense tooltip values ("1763 days 13 hours" → real
  estimate)
• Fixed PoS staker indefinite defer after M1Q switch-over

🔐 BIP39 Recovery Phrase

• 24-word recovery phrase on new wallet encryption
• Password OR recovery phrase unlocks the wallet
• Existing-wallet upgrade via Settings → Recovery Phrase
• Phrase stable across password changes
• getrecoveryphrase RPC

🌐 Testnet — Established and Operational (new in v2.0.0.8)

• Rebuilt from genesis on the deterministic-VRX binary
• P2P port 28092, RPC port 28094 (-testnet switch)
• No premine in testnet genesis
• Voted-consensus activation floor: testnet height 2000
• 6 masternodes + 1 PoS staker; public seed at
  testnet.xdn-explorer.com
• Bugs uncovered during construction (all fixed): same-IP MN
  connection rejection, NAT-hairpin pollution,
  duplicate-MN-identity from masternode.conf-ignorant collateral
  selection, ban storms from over-aggressive scoring,
  enforcement gated behind abandoned -mnadvrelay flag

💰 Balance and Wallet Correctness

Balance display:

• Fixed cold-start balance underreport on large wallets
• Fixed inflated watch-only credit until restart
• Fixed watch-only stake leaking into Spendable Stake
• Fixed P2PK outputs invisible to watch-only tracking
• Fixed rescan-discovered tx timestamps clamped to most-recent

Spent-tracking correctness (CW4 Fix C — new in v2.0.0.8):

• Fixed balance over-report after observing sends/stakes via gossip
• Fixed PoS coinstake input stale spent-flag (writer-side)
• Reorg-safe spent detection (no manual repairwallet needed)
• Spendable and watch-only balance now share the same
  spent-tracking semantics

Coin selection:

• Fixed 2M payments excluding the entire tx from staking

Unlock flow:

• CWallet::Unlock() now tries all master keys

🛠️ Rebuild Wallet (Maintenance)

• NEW: Tools → Compact Wallet — full BDB cursor-level
  dump-and-restore
• Preserves all wallet data (keys, history, watch-only, locks,
  BIP39 mnemonic, address book)
• Encrypted wallets stay encrypted
• Original wallet preserved as wallet.dat.bak
• CLI: -rebuildwallet; hidden RPCs dumprawwallet,
  createfromdumpfile

🌐 Network and Synchronisation

• Fixed difficulty-recovery curve that never engaged in v2.0.0.6
  (cause of long mainnet chain stalls)
• Fixed non-determinism in the post-v2.0.0.6 curve-engagement fix
  that broke from-genesis resync (recovery loop fired against
  wall-clock instead of committed block time)
• Extended historical nBits exception list to 30 entries for
  mainnet stall-recovery blocks where v2.0.0.6 and v2.0.0.8 curves
  produce different answers (one-time archaeology; strict check
  intact for all post-tag blocks)
• Mining-side same-timestamp guarantee — nBits is now computed
  after pblock->nTime is finalised, eliminating the residual
  ~3,600-second hourly-boundary window where miner and validator
  could disagree at recovery steps
• NEW: Devops address rotation activates at mainnet block
  1,400,000 (testnet block 100).
• NEW: Strict devops-address check restored, height-gated to
  fire at the rotation block onwards. Pre-rotation blocks continue
  to validate lax (preserves all canonical chain history); post-
  rotation blocks must pay the correct address or get rejected.
• NEW: Fixed producer/validator off-by-one in the devops ladder
  lookup. Both sides now ask the ladder about the same block by
  construction, eliminating the latent rotation-boundary mismatch
  that has been in the code since the v1.0.1.5 era.
• Fixed wallet banning peers on startup

🖥️ Wallet GUI

Menu / theme:

• New Tools menu with maintenance/system actions
• Dark theme (Settings → Dark Theme)
• In-app DigitalNote.conf editor

Splash / startup:

• New splash screen
• Maintenance Mode splash (rebuild/rescan/reindex)
• Live Rescanning... block N / M progress
• New 16/24/32/48/64/128/256 icons; Windows 11 tray fix

Password / unlock:

• Password generator (20-char random)
• "Forgot password?" link to recovery-phrase unlock
• "For staking only" checkbox hidden by default

Status bar / version:

• MAINNET indicator
• Build date and version embedded from source (replaces
  long-broken v1.0.3.5 self-report from stale git tag)

Transaction display:

• Locally-mined PoW coinbases now appear in the GUI immediately
  (was one-block-late due to a hashPrevBestCoinBase static delay
  from Bitcoin Core heritage; PoS stakers were never affected)
• Double-click opens detail dialog (was a no-op)
• Removed meaningless -000 transaction-ID suffix
• Notification batching during import

Debug console:

• Input disabled with elapsed-time indicator during command flight
• Windows paths typed without quotes work correctly
• -debug=all and -debug=1 now work as wildcard aliases (CW14;
  previously silently did nothing). New debug-logging-guide.md
  covers all 21 categories.

Adding/Removing watch-only addresses:

• New watch-only accounts view
• Remove watch-only prune mechanism (no more restoring wallet from backup to remove)

Visual polish:

• Balance labels min-width (no more clipped "N")
• Copyright year 2018-2026
• Coin Control lock icon visible against light theme
• Qt signal/slot warnings cleared
