Dencun (Cancun + Deneb) upgrade

  • Latest all core devs – execution (ACDE) call video. Summary by Tim Beiko.  Notes from Tim Beiko and Christine Kim:
    • EIP4844: agreed to use big-endian for EL inputs/outputs and use RLP on EL & SSZ on CL via Engine API and discussion on state of KZG libraries
    • Meta discussion if Layer 2 focused EIPs need to go through core devs e.g. EIP6968
    • Cancun upgrade EIP candidates for inclusion to be discussed on next ACDE
  • KZG ceremony available to anyone with 32 mainnet transactions. Wait time is generally zero.
