ACDC #160 Action Items

ACDC #160 Summary

Releases for higher (default) gas limit

  • CL releases require updated gas limit values to 45M
  • Clients plan releases soon with updated gas limits

Fusaka

  • devnet-2

    • Participation rate and proposals are healthy but could be better
    • Some nodes experiencing memory issues with high column participation; some other peering issues
    • Current focus on fixing existing bugs to ready for devnet-3

  • devnet-3

  • With a stable devnet-3, then turn to hardening implementations

    • Focus on testing non-finality scenarios and syncing

  • GetBlobs API Changes

  • Builder API changes

  • Mainnet Planning

    • Rough target timelines from Sigma Prime blog post:
    • General consensus on something like this to target Q4 Fusaka launch
      • although consider the above post a strawman for now
    • Wide agreement that we need the following before going to mainnet:
      • Need extensive testing of:
        • Non-finality scenarios and other failure cases
        • Syncing behavior
        • Network with 1000+ nodes and more realistic P2P conditions
    • Attendees also favored a conservative BPO rollout strategy
      • Initial modest increase at launch, with an observation period to gather mainnet data
      • Then, a second increase early next year aiming for the full theoretical gain PeerDAS can unlock

⠀Glamsterdam EIP Discussion

  • Focus on selecting single headliner EIP per layer
  • Key CL headliner candidates:
    • EIP-7732 (ePBS)
    • EIP-7782 (6-second slots)
    • EIP-7805 (FOCIL)
    • EIP-7919 (Pureth)
    • EIP-7942 (Available attestation)
  • Plenty of discussion on the best way to select a single headliner to start to form the Glamsterdam scope
  • Participants felt it was too early to begin headliner selection today, and after checking with EL representation we decided to coordinate more closely with ACDE which needs more time
  • Reflecting all of the discussion, we decided to wait for Glamsterdam headliner selection until fusaka-devnet-3 is live and healthy
  • Client teams still have time to assemble their opinions on headliner, but there seems to be early interest in a headliner that generally follows the “theme” of scaling
  • We also highlighted the need for better community input as a way to surface to core developers what is best for Ethereum at this time
  • fusaka-devnet-3 is still some time out, but we did agree that allocating two ACD calls, 1 for headliner discussion and 1 for headliner decision, made sense
