Client Team Updates


  • Nethermind:

    • Released an RC with block processing improvements
    • Hired a new QA engineer
      • Talked with Lion about state testing GC (because Hive tests don’t cover that)
      • Could help to prepare those tests
  • Erigon:

    • Was able to run Erigon v3 on Gnosis up to T-50k blocks
    • Running fine, but there might be some issues with block downloading towards the end (might also be a networking issue though)
  • Geth:

    • Guillaume is sick
  • Reth:

    • We want to bring reth to Gnosis (there’s also demand from CoW and other projects)
    • Reth is close to being considered stable
    • Reth is quite extensible, so it might be possible to implement support for Gnosis without having to maintain a fork
    • Will require a state snapshot from the merge, so we don’t have to implement AuRa, as this would be significantly more difficult
    • Reth doesn’t support snap sync yet

Chain Infra

  • Gateway
    • Updated Erigon to the latest version


  • Planning on forking
    • Try to fork it with Nethermind as a generator without modifications
      • Should mostly be implemented by Nethermind but wasn’t battle tested
      • Maybe we should try generating tests for mainnet and compare them
    • Likely some tests will fail, and we can adapt them afterwards
  • Is Erigon running POSDAO tests?
    • Geth for sure isn’t
  • We shouldn’t necessarily assume that passing mainnet tests means that we also pass Gnosis tests, but it might not be reasonable to fork all tests either
    • We should adapt some tests at least
    • The question is where to draw the line


  • EIP-7002 (EL withdrawals)
    • On Ethereum the fee is burned, but we don’t want that on Gnosis Chain
    • Either we keep the same contract and burn the xDAI, or we do a different contract with a different address (which might be worse UX)
    • Burning it shouldn’t be too bad, but it’s not only a “chain revenue” decision, it’s also the fact that the xDAI burned will never be recoverable, which doesn’t really make sense


  • Shutter
    • All the signatures are now being verified
      • Keypers haven’t swapped over to blst yet, but they have test vectors that are working
    • Nethermind is feature complete
    • Debugging an issue where some transactions are not being included when there’s too many
    • Debugging high CPU usage
    • Code review is finished
