October 18, 2023


  • Nethermind:

    • Finished some Gnosis-specific features
      • Configurable EIP-4844 configurations
    • Cancun merged to main branch
    • Kickstarted an initiative to rework the eth_getLogs system to optimize it
  • Erigon:

    • Sync issues (OOM on 32 GB nodes also running CL)
      • Exclusively happens in Docker, GOMAXPROC should be a workaround (4 instead of 24 for example)
    • High disk usage (400 GB with --prune=hrtc vs 170 GB on Nethermind for the standard gnosis preset)
    • Fairly unreliable (I have to restart it every few days at this point, maybe too many attached validators? I miss quite a few epochs on mainnet too but don’t need to restart at least.)
    • Configurable EIP-4844 configurations are merged
    • Working on Erigon 3
  • Geth:

    • Tried the static peers and it seems to work better
    • Still not getting a connection
      • The old branch systematically uses eth/66 and that works
      • The new branch gets disconnected when trying to connect to eth/66


Chain Infra

  • Gateway
    • Discovered a bug in the load balancer that resulted in 0.5 to 1% of errors at the current load
      • Sudden increase in eth_getLogs, which are typically quite slow on the nodes, which were subsequently falling behind
      • The solution was to account for this slowness


  • The public RPC was down during the weekend, but that was because of Gnosis.

Hive Tests

  • Solved the configuration issues for Dencun
  • Working on an error when sending blobs


  • Has Erigon joined?
    • thorax/erigon:docker_gno_dencun_devnet_0
    • --chain=gno_dencun_0
    • Issues with the internal CL
    • Not tested yet


  • Automatic sync tests
