v4.0.0-rc1 Pre-release
Pre-release

Upgrade Notes

For Testnet network users the network has been rolled back to block 1,150,000. This release requires either a reindex, restarting from snapshot or a clean sync. The expected hash on block 1,150,000 is 2f0b131e15bdb6e5ecbd0e8fd4f9db798db59aa3c78a3b352594b8db341e1f33.

For Changi network users upgrading from any release before beta15, this release requires either a reindex, restarting from snapshot or a clean sync due to changes in the EVM state. Failure to do this may result in an inconsistent EVM state.

Summary

Note: This is a release candidate pre-release. This is NOT meant for use on production systems.

  • Version: 4.0.0-rc1

Testnet EVM

  • EVM RPC Port: 18551
  • EVM ChainID: 1131

Changi

  • P2P Port: 20555
  • DFI RPC Port: 20554
  • EVM RPC Port: 20551
  • EVM ChainID: 1133
  • Network name: changi
  • Rest of the parameters are exactly the same as testnet3, which continues to run in parallel.

v3.2.8

Recommended Upgrade

  • Security improvements
    • Rate limit ADDR P2P messages.
      • This prevents a potential DoS attack vector where malicious actors can cause resource exhaustion of the node host.
  • Performance improvements
    • -walletfastselect flag can be used to speed up UTXO selection for large wallets
      • This only works for simple utxo unlock scripts.
      • Using this option will fail to select complex scripts unlock scripts like multi-sig.
      • This can be set as a global default in defid or passed to defi-cli to set per-request context.

Upgrade Notes

  • For >= 3.2.4, no reindex needed. Drop-in upgrade.
  • For >= 3.2.0 and <= 3.2.3, reindex is recommended, but optional and can be drop-in upgrade.
  • For nodes >=3.0.x, one of the following is required:
    • Sync from any of snapshots from the DeFiChain team (below)
  • For all other updates, one of the following is required: a fresh sync, the most recent snapshot.
  • For nodes that are being restored from recent snapshot, as with all updates before: -rescan for the wallet txs and additionally -spv_resync for users who hold BTC. If either isn't used, they may not be shown in the wallet until rescanned/resynced.

Flag Changes

  • Both defi-cli and defid:
    • Added:
      • walletfastselect
      • walletcoinoptskipsolvable
      • walletcoinopteagerselect
  • defid:
    • Added:
      • maxaddrratepersecond
      • maxaddrprocessingtokenbucket

RPC Changes

  • getpeerinfo:
    • Added:
      • addr_processed
      • addr_rate_limited

v3.2.7

Recommended Upgrade

Key highlights

  • Stability fixes:
    • Fixes missing tokens on the balance RPCs in edge cases even though consensus level balances were unaffected.
      • Issue: Nodes missed to index a cascaded chain of calculation that resulted from spent governance voting reward tokens
  • Performance improvements:
    • getburninfo calculation is now done in parallel and is memoized on first call. Only the differential heights is recalculated making it much cheaper to be called.
    • Validation of vault liquidation logic is now done in parallel when hardware supports it and should result in visible improvements on the sync performance with more hardware cores.
  • Additional internal refactors and synchronization improvements

Upgrade Notes

  • For >= 3.2.4, no reindex needed. Drop-in upgrade.
    • Reindex is optional, however recommended for wallets affected by (#1763)
  • For >= 3.2.0 and <= 3.2.3, reindex is recommended, but optional and can be drop-in upgrade.
  • For nodes >=3.0.x, one of the following is required:
    • Sync from any of snapshots from the DeFiChain team (below)
  • For all other updates, one of the following is required: a fresh sync, the most recent snapshot.
  • For nodes that are being restored from recent snapshot, as with all updates before: -rescan for the wallet txs and additionally -spv_resync for users who hold BTC. If either isn't used, they may not be shown in the wallet until rescanned/resynced.

Flag Changes

  • None

RPC Changes

  • Undocumented API for advanced uses only: votegovbatch

Additional Notes

  • While this release includes many performance improvements, a consequence of #1789 is that listaccounts and gettokenbalances APIs is expected to be slower due to a set of band aids that are applied. These are temporary band aids that will be removed in one of the future releases - has been used for now to workaround the source indexing issue without having to touch consensus related code paths to take the safer approach.

Important Information

During one of our pre-hardfork checks, we identified that some of the recent snapshots before Jan 10, 2023 provided by the following sources were created by nodes that were updated incorrectly, resulting in inconsistent data:

All of the incorrect snapshots have now been removed from the above sources, regenerated and verified to be correct as of Jan 11, 2023.
Freshly synced nodes with 3.1.x nodes are unaffected and are ready for the Grand Central Epilogue network upgrade. For those that have used any of the above sources to bootstrap the network, please update your nodes from the same sources again.

Recent verified snapshots:

Optional Upgrade

  • Additional filters and pagination for on-chain governance related RPCs
  • Optional support for time based TX ordering miner policy
  • SPV related fixes that hangs the shutdown process under certain conditions
  • Accounting fixes for getburninfo related to BurnTokenTx

Update of mainnet node to v3.2 before the chain upgrade block is REQUIRED.
