TechFlow, September 12 — According to Christine Kim's summary of the 220th Ethereum Execution Layer Core Developer Meeting (ACDE), Ethereum developers have established an optimistic timeline for the Fusaka upgrade during the latest ACDE #220 meeting, aiming to deploy the upgrade to mainnet as early as November or by year-end. Key milestones include finalizing the block heights for all public testnet upgrades on September 18, releasing testnet-ready client versions on September 22, followed by upgrading the Holesky, Sepolia, and Hoodi testnets on September 29, October 13, and October 27, respectively.
Currently, Fusaka Devnet-3 still faces issues such as low network participation (around 50%). The development team is investigating the cause, with preliminary analysis suggesting it is related to the Engine API methods rather than the Fusaka features themselves. Meanwhile, Fusaka Devnet-5 has launched and will be used to analyze blob parameter hard fork scenarios.
In addition, Tim Beiko proposed revisions to the Ethereum protocol upgrade process, including a minimum 14-day interval between client releases and testnet forks, approximately two weeks between testnet forks, and at least a 30-day interval between client releases and mainnet forks. The meeting also discussed multiple EIP proposals for the Glamsterdam upgrade, including support for post-quantum signature algorithms.
