Highlights
A new proposed timeline for the Fusaka hard fork, with mainnet coming as soon as December 3
A new AI team at the Ethereum Foundation
New research regarding Ethereum’s state growth
A new EVM/Solidity debugger, EDB, with an impressive demo

AllCoreDevs Update
Whereas previously we were effectively publishing call notes for the AllCoreDevs calls, going forward, we will summarize points regarding AllCoreDevs calls salient to EVM application developers, rollup developers, and security researchers. More detailed breakdowns can be found at
’s Substack, Yash Kamal Chaturvedi’s highlights, Ethereum PM issues, or the Ethereum Magicians forum.The most notable news piece over the last week is a new tentative timeline for testnet forks, as well as the mainnet fork. Starting from Holešky, we should be seeing BPO forks every week, as well as subsequent new testnet forks every two weeks, including Sepolia and Hoodi. Finally, we should be seeing the Mainnet fork in December at the earliest. See this document for a detailed breakdown.
Curiously Fusaka devnet 3 ran into an unplanned unfinality event after finalizing, dropping from ~78% participation to ~63% on the day of ACDT. By the time of ACDC, finality had been restored, but there was no discussion at that time regarding what the root cause was. Devnet 5 was launched on September 10, with issues cropping up and being ironed out, including one regarding the c-kzg-4844 library. Peep the recent audit report by zkSecurity on that one.
Regarding Glamsterdam, a reminder was given to have all proposed EIPs in by Fusaka mainnet releases (which are due on November 3). For context, headliner EIPs (ePBS and BALs) are already scheduled, but it is time that developers deliberate on the inclusion of other EIPs.

Research Update
MEVless protocol, the way to anti-MEV by Lawliet Chan
A protocol called MEVless is proposed to eliminate MEV by separating transaction ordering from execution, concealing transaction content during ordering, and publishing committed order sequences to the network, thereby preventing miners from exploiting transaction information for MEV attacks while maintaining low overhead and deterministic, verifiable execution.
