Client Team Updates

EL​

• Nethermind:

  • Nothing new
    • Working on Pectra and half-path / snap sync server

• Erigon:

  • Working on Pectra and Erigon 3

• Geth:

  • Issue when the first blob was included in a block
  • Currently less than 2 weeks behind head
  • Then will test snap sync with a new geth node

Chain Infra

• Gateway
  • No updates

Innovation

• Shutter

  • The first Shutter transaction was included!
  • Transaction submitted to sequencer contract and included in a block
  • However, keypers are mocked for now, so the keys are hard coded
    • Because the keypers are still using the BN curve rather than BLS
    • Will require some changes from Shutter and then some testing
    • No ETA yet
  • The libp2p issue hasn’t been resolved yet, so the connection breaks after around half a hour

• Verkle Tree Integration

  • Gnosis Chain has less time per block to do the transition
  • What’s the upper bound for time we can take to do the transition?
    • One issue is that snap sync is not entirely figured out for the transition yet, so syncing could be a bit more difficult (but at most nodes would have to sync 2 months worth of blocks, which on Gnosis Chain is not that huge of an issue, and it likely doesn’t change anything for Erigon at least)
  • Ethereum is targeting 2 weeks, on Gnosis Chain with identical parameters it would take 4x longer, so 2 months (mental math, to be checked)

Client Team Updates

EL​

• Nethermind:

  • Planning on releasing half-path
    • Still a few weeks away
    • Will have around half the speed of geth for serving snap sync

• Erigon:

  • Small release today with fixes for Caplin (2.59.1)

• Geth:

  • Was able to go all the way to Dencun
  • Will have to rebase now for Dencun support

Chain Infra

• Gateway
  • The eth_getLogs service unavailable error happens on the public RPC when the servers are overloaded
    • With an API key that doesn’t happen

Hive Tests

• No updates

Innovation

• Shutter
  • Managed to fix the threading issue
  • The validator is able to run but can’t produce blocks yet because there’s an issue with passing the decryption keys
    • Might be the protobuf implementation
    • Once this is done, block production should work

Client Team Updates

EL​

• Nethermind:

  • Nothing in particular
  • Starting to think about the next release
    • Might potentially include half-path and a snap sync server
    • Expected in a few weeks
  • Progressive on paprika as well, which can’t fast sync and would thus require snap sync servers

• Erigon:

  • Going to make a new release with post-dencun fixes today
  • Includes a feature for more aggressive pruning of logs and receipts
    • Will only be enabled for new nodes (i.e. synced from scratch)
    • Existing nodes will have to resync
  • Transaction logs are filling the network quite a lot, at least in the last 1-2m blocks
    • This behavior doesn’t happen in Chiado / Sepolia
    • This causes the bloating issue
    • With the default pruning flags, full nodes should be around ~500 GB and archive nodes should be ~1.3 TB
    • One can also use a more aggressive pruning strategy (i.e. last 1k - 5k blocks), which of course would also result in a smaller node. Default is 90k blocks.

• Geth:

  • Not present

Chain Infra

• Gateway
  • Deployed Erigon + Lighthouse on mainnet before Dencun and went fine

Hive Tests

• No updates

Innovation

• Shutter
  • Managed to register the validators
  • Looking into a couple of issues
    • Race condition
    • Libp2p library on MacOS specifically
  • 2 week ETA should still be realistic

Mainnet

• 95% attestations immediately after the hard fork
  • Some issues with the Gateway RPC
  • Might be fixed, Alex will double check

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

  • 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
