Client Team Updates


  • Nethermind:

    • Released a bug fix version that is also Chiado ready (v1.25.1)
      • There might still be another release before Chiado
  • Erigon:

    • Philippe still hasn’t tested the pruning image
    • Will do a new release this week for Chiado
  • Geth:

    • Not present

Shadow Fork

  • Deployed a new proxy to the deposit contract implementation
    • 0x4A9Eaee643070823afC7477bC0910585E5855e19
  • Carlos already started some nodes, so we’re moving into the shadow fork slowly but surely
    • Potentially ready this week, but will require a custom Erigon image
    • Would be nice to fix erigon init command so that we don’t require custom images constantly for devnets / shadow forks etc
      • There’s another linked issue to this so not straightforward to solve

Chain Infra

  • Gateway
    • No specific news


  • Chiado
    • Everything should be ready
    • No concerns at this point

Hive Test

  • Fixed the actions that were failing, which were due to misconfiguration in the clients
  • Erigon is still missing 3 tests that should not be failing
  • Building a tool to push hive test logs to Telegram every day


  • Issues with Nimbus
    • Wasn’t including the KZG ceremony for Gnosis
      • Fixed in 7443a4ac086000b1d2a7d5af6685cc5ef9537b9d
    • Still forks off
  • Issues with Erigon
    • Creates empty blocks (or at least with less transactions)
      • There might be a bug in the transaction pool
      • Some recent commits fix different issues related to overflowing in relation to warning logs from the failing nodes
      • Pending PR for a mdbx race condition
      • Somnath will update the image for devnet 3
      • Somnath will also work on another suspected issue
  • Issues with Caplin (experimental) are expected
  • Erigon also has occasional issues with block production on Ethereum mainnet
    • Their transaction pool likely needs some love
  • Carlos will check if clearing the txpool and restarting the node solves the issue for some time
  • Goerli’s devnet is probably mostly Geth + Nethermind so maybe the block production bug for Erigon hasn’t been caught there
  • Somnath will release a new version later today when the PRs are approved
  • Some issue with Erigon + Lighthouse
    • Lighthouse lost its peers, restarted the node and now it works again


  • Shutter
    • Still no Docker image for testing
      • Promised one for end of this week
      • Probably busy with their DAO launch
      • Required to work on the networking layer, so it’s blocking the Nethermind implementation significantly
      • The block building and cryptography parts can be worked on currently at least
        • Lot of things to implement for cryptography and the Nethermind team is discussing with Shutter to change some cryptography protocols (BLS12-381 vs BN254)
