Ethereum Developers Set Deadlines for Upcoming Glamsterdam Upgrade

According to PANews, the 223rd Ethereum Execution Layer Core Developers Meeting (ACDE) outlined key deadlines for the upcoming Glamsterdam upgrade. Developers have set October 30 as the deadline for submitting EIP proposals, with the final scope of code changes to be confirmed by November 27. A significant focus of the meeting was the Fusaka mainnet timeline. Ethereum Foundation coordinator Alex Stokes proposed December 3, 2025, for the Fusaka mainnet upgrade, with subsequent Blob Parameter Optimization (BPO) scheduled for December 9 and January 7, 2026. All execution layer client teams, including Geth, Nethermind, Reth, Besu, and Erigon, agreed on the feasibility of this timeline. The Hoodi testnet is set to activate the Fusaka version on October 28, marking the final test upgrade before the mainnet launch. Meanwhile, the Holesky testnet is expected to close next week. For the Glamsterdam upgrade, developers plan to launch a multi-client developer testnet to test the Block Access Lists (BALs) feature. Key deadlines include proposal submission by October 30, client team feedback by November 6, and final scope confirmation by November 27. The Ethereum Cat Herders team will hold open office hours on October 28 to assist EIP authors with proposal submissions. In technical discussions, EF researcher Maria Silva presented two options to enhance Gas unit precision, with plans to convert related research into EIPs for consideration in the Glamsterdam upgrade. Additionally, EIP 8058 proposes a "deduplication discount" for developers deploying the same contract multiple times to reduce state bloat. Proposals EIP 7667 and EIP 6873, both related to Verkle data structures, have been removed from consideration as they no longer align with the current roadmap. Stokes emphasized that the core objective is to finalize the technical scope of Glamsterdam by the end of November, laying the groundwork for the mainnet upgrade by the end of the year.
