Client Team Updates

EL

• Nethermind:
  Working on Shutter
  No more xdai(_archive) configs in the new Nethermind release (1.21.0)
  Potential issues in Avado
• Erigon:
  The header download functionality is acting up a bit from time to time
  Somnath is working on it
  Transaction pool should work on Gnosis but hasn’t gone through extensive testing
  Same for validating
• Geth:
  Was able to sync 1.5m blocks
  Geth is now running out of memory on the old branch
  Did a rebase and is cleaning up some code, but that new branch isn’t syncing

Chain Infra

• Gateway
  Is running 100% of the RPC traffic of the Gnosis RPC

Dencun

• EIP-4788
• We believe that the HISTORY_BUFFER_LENGTH variable doesn’t matter that must
• Having 1.14 days or 0.47 days give roughly the same UX
• We’re going to keep that number and thus deploy the exact same contracts
• Gnosis: https://gnosis.blockscout.com/address/0x000F3df6D732807Ef1319fB7B8bB8522d0Beac02
• Chiado: https://gnosis-chiado.blockscout.com/address/0x000F3df6D732807Ef1319fB7B8bB8522d0Beac02

EIP-4844

• Big block experiment
• The network suffers from big blocks (we spammed it super cheaply for a 10 - 20 minutes)
• The head participation went down quite a bit (close to 20%)
• Min gas price will be 1 gwei to be on the same scale as normal transactions (1 gwei minimal priority fee)
• Nethermind wrote a tool to spam blobs and it broke a lot of clients
• These might just have been early implementation bugs
• EIP-7514
• https://hackmd.io/jWVHqjmrQ1aXtpt6iTNTdw?view
• An attacker could get a 67% share in the network in 2.5 days because the entry queue scaled way too quickly

Hive Tests

• Merged the dencun tests from upstream
• Will work with Egor to catch up as fast as possible

Devnet

• We have a Devnet with Nethermind, Teku and Lodestar
• Lighthouse doesn’t work for custom configs anymore, Carlos is in communication with them
• There are some issues, probably related to peering
• Also deployed the blob scanner and spammer
