This version introduces a preview of ZK-based DKG signature verification added to KeyManagement system contract and the support of ZK-based DKG signature generation at the dBFT side (this feature will be auto-enabled by dBFT once KeyManagement contract is upgraded by the network maintainers). Note that this feature is not yet finalized and is a subject of polishing for further releases. Also, this version adds a support for NeoXEthSig fork that switches to a canonical form of TPKE block signatures. In addition to that, this version contains a set of optimisations improving the efficiency of block producing process and a set of dBFT-related bug fixes.

This version is fully compatible with v0.3.2 and does not require DB resync. For TestNet nodes upgrade, the DB reinitialization with updated genesis configuration is required (NeoXEthSig fork is scheduled at block 3750000 of TestNet). To upgrade MainNet nodes from v0.2.2, DB reinitialization is required (since we've removed NeoXBurn from the list of known forks; note that we don't yet enable NeoXDKG, NeoXAMEV and NeoXEthSig forks on MainNet). Also, anti-MEV keystore should be generated and provided to the node on startup following the notes from v0.3.0 release.

New features:

  • NeoXEthSig hardfork fixing the format of TPKE block signature (#463)
  • ZK-based DKG signature verification support in KeyManagement contract (#442, #470)
  • ZK-based DKG signature generation support in dBFT (#444)

Behaviour changes:

  • txpool.signaturecache CLI flag is renamed to txpool.amevcache (#457)

Improvements:

  • configurable dBFT status statistics period (#449)
  • documentation improvements (#457)
  • refactoring of encrypted transactions pool (#468)
  • optimize conversion of dBFT CN index to DKG CN index (#458)
  • use local mempool for dBFT proposal verification (#466, #476)

Bugs fixed:

  • panic in encrypted transactions pool on attempt to remove expired transaction (#447)
  • empty pending consensus list on new epoch start in Governance contract (#460)
  • DKG routine is not synchronized with miner interruption (#475)
  • panic on dBFT payload processing during miner node shutdown (#467)
  • non-canonical format of TPKE block signature (#463)
  • panic in dBFT on PreBlock verification (#473)
  • consensus doesn't work on single-node privnet (#315)
  • inability to retrieve ZK version from old KeyManagement implementation (#478)
