Ethlabs recommends postponing the decision on the Glamsterdam upgrade, with external audit results expected to be announced on November 16.

November 10 - According to a post by Ethlabs, the team recommends not making any decisions on the Ethereum Glamsterdam upgrade until the situation is clarified. Ethlabs stated that it has been monitoring and analyzing reports on the potential impact of EIP-8037 and EIP-8038 on deployed smart contracts for over two weeks. The post indicates that the Ethereum Foundation has commissioned Chain Security and Dedaub to conduct external audits, with results expected to be published on November 16, and calls on application developers to run the self-check tools provided by the Foundation, disclose potential issues to glamsterdam@ethereum.org, and participate in the Q&A session at the ACD Testing meeting on the same day.

According to the post, Glamsterdam plans to raise the block Gas limit from 60 million to 200 million, approximately a 3.33x scaling, and adjust the pricing of certain basic operations. Contracts that rely on the absolute prices of these operations will be affected. Observed impacts include: repricing makes state relatively more expensive compared to computation, but the overall Gas limit increase can partially offset this; contracts or tools that hardcode fixed Gas cost assumptions will be affected; Gas metering updates also cause some deployed contracts to exhibit unexpected behavior. Ethlabs states that none of the above situations are currently exploitable and are only relevant to the possibility of deploying the upgrade under current specifications.

Ethlabs recommends not proceeding with specification changes or scheduling the Hoodi testnet fork until audit findings are published and a clear position is formed. Regarding upcoming meetings, ACDConsensus on November 12 is expected to provide only a brief update, ACD Testing on November 16 will hold a public Q&A, and ACDExecution on November 19 may take a position on the findings, including whether to modify specifications and whether to proceed with the fork under the current plan. Ethlabs states that the final decision rests with all core developers, and if the scale of the issues is unacceptable, the team is also prepared to consider modifying specifications or adjusting the scope of the upgrade.
