DigiByte Core v9.26.0-rc44

DigiByte Core v9.26.0-rc44 Release Notes

RC44 is the DigiDollar release candidate for a full public testnet reset and
the 35-slot oracle roster. Mainnet and testnet26 now expose 35 active MuSig2
oracle slots with a 7-signature quorum. Slot 28 now uses the DigiHash Mining
Pool key, slot 31 uses the Peer2Peer / DigiRoos key, and all 35 configured
slots contain valid compressed secp256k1 oracle keys.

Testnet26 Reset

RC44 starts a fresh public DigiDollar testnet: testnet26.

RC41/RC42/RC43 used testnet25. RC44 does not. Old testnet25 blocks,
chainstate, peer addresses, cached oracle messages, signed nonces, and
DigiDollar positions are not RC44 proof. Back up wallet and oracle key material
before wiping old data, then start clean on testnet26.

Operator Migration

1. Stop RC43 or older testnet nodes.
2. Back up wallets and oracle key material.
3. Do not copy old blocks/, chainstate/, peers.dat, oracle messages, or cached MuSig2 state from testnet25.
4. Start RC44 with -testnet, using the new testnet26 data directory.
5. Open and advertise P2P port 12033.
6. Update static addnode and oracle endpoint config from port 12032 to 12033.
7. Confirm getblockchaininfo reports the RC44 genesis hash above.
8. For mainnet, generate a new wallet/oracle key. Keep existing testnet keys for testnet26 only.

Oracle Roster

Mainnet and testnet26 now use 35 active oracle slots and require 7 valid MuSig2
signatures per oracle bundle. Active oracle IDs are 0 through 34; ID 35
is outside the configured roster and must be rejected.

New slots added since the RC43 active roster:

All oracle operators, miners, seeders, and testnet nodes must run the same RC44
binary before signing or mining on the new public testnet.

Changes Since RC43

RC44 carries forward the RC43 wallet-state stabilization work and adds the
release reset and final oracle launch roster:

• New testnet26 chain with new network magic, genesis block, P2P port 12033,
  and a clean data directory.
• Mainnet and testnet26 oracle consensus expanded from the RC43 active set to
  35 active oracle slots with a 7-signature MuSig2 quorum.
• Added final oracle slots 21-34, including DigiHash Mining Pool at slot 28 and
  Peer2Peer / DigiRoos at slot 31.
• Added getoraclesigners to decode MuSig2 bundle signer IDs and participation
  details from oracle bundles.
• Hardened oracle P2P activation gating so oracle relay, heartbeat relay, and
  DigiDollar state-changing actions require the correct DigiDollar activation
  state.
• Hardened MuSig2 relay against stale, far-future, negative, and epoch-zero
  edge cases.
• Fixed stale oracle-bearing getblocktemplate cache reuse so miners rebuild
  templates when oracle commitments expire.
• Improved wallet DigiDollar UTXO tracking, redeem pending-state handling,
  redeem change history, stale redemption reconciliation, collateral outpoint
  resolution, restored wallet key visibility before startoracle, and rapid DD
  send safety.
• Updated operator scripts for testnet26, port 12033, RPC 14026, genesis
  validation, wallet-key startup, datadir stop behavior, and stricter RPC
  credential-file permissions.
• Cleaned stale operator documentation and scripts for private-key CLI
  assumptions, retired getoracleinfo references, retired testnet/port values,
  and older 17/21/24-oracle wording.
• Polished Qt DigiDollar surfaces for QR save failure handling, cross-network DD
  receive-request filtering, clearer transfer finality copy, volatility mint
  rejection handling, pending redeem display, and system-health polling.

Validation

RC44 was validated after regenerating the final testnet26 genesis parameters
for the 7-of-35 oracle reset:

• digibyted, digibyte-cli, digibyte-wallet, and test/test_digibyte
  release build targets.
• Focused oracle tests covering MuSig2 activation, oracle RPC, roster alignment,
  and oracle config.
• Full unit suite: 3396 Boost test cases.
• DigiDollar operator-surface lint and git diff --check.
• Full functional suite: 375/375 passed with expected environment/unsupported
  skips.
