Client Team Updates

EL

  • 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

Dencun

  • 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

Devnet

  • 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

Innovation

  • 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)

    • Checked the logs for Nimbus + Erigon missed slots for devnet 3

EL

  • Nethermind:

    • No specific updates
    • Preparing a new release with performance improvements
      • RC this week
      • Next week full release
    • One more release with experimental state db changes with large improvements
      • Initial tests were very promising
  • Erigon:

    • Testing change to make validator nodes lighter (better pruning, i.e. just keep receipts for the deposit contract)
    • Somnath will work on a release so we can test it on the devel branch
  • Geth:

    • Not present

Chain Infra

  • Gateway
    • No specific updates
    • Can test new Nethermind releases, just ping Anton on Telegram
      • nethermindeth/nethermind:release-1.25.0

Dencun

  • Chiado
    • Tentative date around end of January, ideally Jan 31st (during the core dev call)
    • Around the same time as Sepolia
    • Lion will run the script to find optimal epochs (right time and epoch boundaries)

Hive Test

  • Migrated more tests for Cancun, but in the process broke withdrawal tests
    • These are being worked on currently

Devnet

  • Solved Nethermind related issues
  • Some issues with Erigon-Teku
  • We had one node missing slots (Erigon + Teku)
    • Technically one forked, but it’s likely because it was out of sync with the network and then produced a block itself
  • We need to add Lighthouse (unstable) and Nimbus (v23.11.0)
  • We need to observe the network a bit more
  • How are Teku nodes configured currently, as the preset isn’t set up in the code base yet?

      • Maybe it’s a bit early to upgrade all nodes

      • This is currently in the master branch, not officially released
    • Working on one regression for a cancun related issue
  • Working on Nethermind 2, a big state redesign that would include performance a lot that would allow for snap servers
