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)
