PANews reported on October 24 that according to the minutes of the 223rd Ethereum Executive Core Developers Meeting (ACDE) summarized by Christine Kim, developers have set next Thursday (October 30) as the deadline for submitting EIP proposals for the Glamsterdam upgrade, and plan to finalize the scope of code changes included in the upgrade before November 27.
Conference highlights include:
Fusaka Mainnet Timeline Confirmed – Alex Stokes, Head of Coordination at the Ethereum Foundation, has proposed a Fusaka mainnet upgrade for December 3, 2025, with subsequent Blob Parameter Optimization (BPO) scheduled for December 9 and January 7, 2026, respectively. All Execution Layer (EL) client teams (including Geth, Nethermind, Reth, Besu, and Erigon) have confirmed this schedule as feasible.
The Hoodi testnet will activate the Fusaka version on October 28, which is the last test upgrade before the mainnet launch; the Holesky testnet is expected to be closed next week.
Glamsterdam Upgrade Path - Developers plan to launch a multi-client developer testnet to test the Block-Level Access Lists (BALs) feature.
Proposal submission deadline: October 30
Client team feedback deadline: November 6
Final scope confirmation: November 27
The Ethereum Cat Herders team will hold public office hours on October 28th to assist EIP authors in submitting proposals.
Key Technical Discussions - EF researcher Maria Silva proposed two solutions to improve the accuracy of gas units and converted the related research into EIPs for Glamsterdam's consideration. Separately, EIP 8058 proposed providing "deduplication discounts" to developers who deploy the same contract multiple times to reduce state bloat.
Removal Proposals - EIP 7667 and EIP 6873 (both related to the Verkle data structure) have been removed as they no longer fit within the current roadmap.
Stokes concluded that the core goal is to finalize the technical scope of Glamsterdam by the end of November, laying the foundation for the mainnet upgrade at the end of the year.
