Client Team Updates

EL

• Nethermind:

  • Shutter
    • Working on Shutter’s cryptographic implementation
    • Still no Docker image for the testnet

• Released 1.25.0 with performance improvements, geth compatible tracers and JSON-RPC improvements (was a preview last week)

• Erigon:

  • We need to test the image for aggressive pruning provided by Somnath
  • Checked the logs for Nimbus + Erigon missed slots for devnet 3
    • Could not find a reason why the payloads would be invalid
    • The sequence of requests for payloads might not be optimal on Nimbus’ side (some type of race condition?)
    • There might be a bug in the transaction pool for Erigon during block building
      • Discovered because of a Hive test failure on Ethereum
      • Somnath is looking into it
  • Released a new version

• Geth:

  • Not present
  • There’s still the issue about the synced state not being considered as the canonical one
  • Guillaume is looking into implementing full sync with AuRa

Shadow Fork

• We want to shadow fork Chiado to make sure that everything works
• We need a copy of the deposit contract deployed on Chiado
  • I.e. just a new proxy that points to the same implementation

Hive Test

• Fixed the actions that were failing, which were due to misconfiguration in the clients

  • Overall the network is healthier than devnet 2
• Two issues
