Shapella (Shanghai + Capella) upgrade

  • Latest core devs call video.  Summary by Tim Beiko.  Notes from Tim Beiko & Christine Kim:
    • Shanghai confirmed to target March prioritizing withdrawals plus warm COINBASE, PUSH0 & limit/meter initcode
    • EOF EIPs (3540, 3670, 4200, 4750, 5450) will be included in Shanghai only if implementations tested by January 5 and devnets successful by January 19
    • EIP4844 agreed as main feature for next upgrade quickly after Shanghai (Cancun), with EIP1153 (transient storage) & EIP2537 (BLS precompile) as candidates for inclusion
  • Withdrawals impact on builder layer: relays & builders just need to run correct client versions
