Client testing call #22, January 27, 2025

Interop Testing Call (Jan 27, 2025)

Meeting Summary: Devnet 5, Devnet 6, and Related Updates

Pectra Devnet 5

  • Devnet-5 is finalizing successfully again after addressing key issues.
  • Client Updates:
    • Erigon: Fix implemented, resolving key issues and enabling finalization.
    • Lodestar: Syncing is functional but block import issues persist (only 6 blobs present in blocks with more than 6).
    • Prysm: Issue under investigation, early stages of debugging.
    • Lighthouse: Debugging ongoing; no update yet.
    • Geth: Issue appears resolved, pending verification.
    • Grandine: Node resynced, debugging continues, and it is now proposing blocks.
    • Besu: Block processing issue identified, tracing and debugging underway.
  • Hive issues remain a blocker for Devnet-5 and need resolution before progressing to Devnet-6.
  • Decision: Continue with Devnet-5 until fixes are in place, then transition to Devnet-6.

Pectra Devnet 6

  • Spec: @ethpandaops/pectra-devnet-6
  • Timeline: Tentative release this week, dependent on client readiness and passing Hive tests.
  • Consensus specifications are finalized.
  • Execution spec test release this week, all PRs in place.
  • Plan:
    • Add Devnet-6 to Hive for clients already passing Devnet-5.
    • Clients that pass devnet-6 hive can then join devnet-6.
    • Enable MEV from the start of Devnet-6 (Bloxroute ready for testing).
  • Next steps: Ensure all clients address outstanding issues to meet the timeline.

PeerDAS

  • Updates to configuration values shared in the PeerDAS channel.
  • Interop testing underway, progressing well.
  • Lighthouse team close to PeerDAS devnet readiness, working on improvements and testing stability using Kurtosis on Kubernetes.

EOF

  • Preliminary testnet spec shared: EOF Testnet Plan.
  • Initial fuzzing with Geth, Besu, and REVM shows no errors in overnight run—indicating readiness for Osaka Devnet.
  • Decision: Launch EOF devnet next week following Pectra spec finalization.

Hive Updates

  • ethpandaops have added a github action for hive, which executes all clients in parallel, resulting in a 6x speedup and at lower cost.
  • Hive integration for testing Devnet-6 is a priority, as it remains a critical tool for identifying client issues.

Key Links Shared in the Call

Next Steps

  • Continue debugging and fixing outstanding issues in Devnet-5.
  • Transition to Devnet-6 as soon as Hive tests are passed.
  • Plan EOF devnet launch for next week.
  • Ongoing PeerDAS and Kurtosis testing to ensure stability over time.

Thanks for the notes @poojaranjan!
