Recommended Upgrade

This is a recommended update that fixes a crash in 3.0.x that gets the chain to be stuck on valid TXs.

Important Info:

  • 3.0.x nodes continue to be supported in the network.
  • There is no requirement to upgrade to be a part of the network either to stake or validate.
  • The key purpose of v3.1.1 was to align the network quickly and prevent network splits in the interim and synchronise the network.
  • The bug was caused due to a missing revert in the implementation for DeFiCh/dfips#228. This feature has now been turned off is not expected to be enabled until the next planned network upgrade.

Upgrade Notes

  • For nodes >=3.1.0, it's a drop-in upgrade.
  • For nodes >=3.0.x, one of the following is required:
    • Sync from any of snapshots from the DeFiChain team (below)
    • Any of your own snapshots or data backups before block 2480466 (b41a1d51d80381d3b14be24bc8b2a5524e1c698f5d7cffe5ec4f7b6807ce935a).
    • Fresh sync.
  • 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.
  • For other nodes, one of the following is required: a fresh sync, the most recent snapshot.
