Client Team Updates

EL​

• Nethermind:

  • Nothing in particular
  • Released an experimental version with snap server enabled
    • We can slowly start deploying nodes that are can serve snap sync
    • Enabling the snap server requires a full resync
    • Working on 3 solutions for the state db
      • Path based
      • Half path
      • Paprika
    • Release schedule not defined yet, and will depend on development progress, because paprika will require a new hard fork again after half-path
    • Considered for the next release, but after Dencun for sure
    • Might be a locked behind a flag rather than being a default to start with
    • When snap sync becomes faster than fast sync this feature will be enabled by default

• Erigon:

  • Nothing in particular
    • Looking into why the database is bloating up still

• Geth:

  • Found the issue after London and started syncing again
  • Was missing a location for the free transactions in London
    • At 300k blocks past the last issue (which was on block 11 after London)
  • Next issue will likely be the merge, and after the merge everything has already been tested to work
  • Will then have to rebase for the latest Dencun changes

Chain Infra

• Gateway
  • The RPC nodes with Lighthouse for both Erigon and Nethermind
    • Will likely deliver validators with Erigon this week

Hive Tests

• No updates

Innovation

• Shutter
  • Made some progress on p2p connections
  • Working on integrating the different parts together
  • Will then setup a test validator
  • The first test validator might be ready in 1-2 weeks

Mainnet

• Issue with blob gas being burned instead of added to the fee collector
  • Going to be postponed

Shadow Fork

• Nodes still aren’t done syncing
  • They’re very close to tip but don’t catch up
  • Only Erigon nodes

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)

• 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

  • 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

• 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?
