Eth News and Links

Dencun (Cancun + Deneb) upgrade

• Latest all core devs – execution (ACDE) call video. Notes from Christine Kim:

  • Impact of EIP6404/6466 SSZ transition on existing contracts using RLP: EIP6404 is low impact whilst EIP6466 is manageable due to upgradeability of 3 impacted projects [Reminder: SSZ EIPs already removed from Dencun upgrade]

  • Dencun updates: devnet issue tracker, plan to stress test EIP4844 on devnet 7 & in parallel develop full set of Dencun EIPs for devnet 8

Research
