Ethereum Developers Merge Critical Glamsterdam Fix to Protect Validator Staking Deposits

Ethereum core developers have merged a critical fix into the consensus specifications for the upcoming Glamsterdam upgrade, resolving a deposit-handling flaw that could have misallocated validator staking deposits to block builders sharing the same public key. First flagged by Lido Chief Protocol Architect George Avsetsin on October 12, the proposal was initially closed on October 19 due to lack of client support. Maintainer Justin Traglia officially merged the correction on October 26 after differential testing across clients like Prysm and Lodestar. Glamsterdam's scheduled October 26 Hoodi testnet activation remains postponed to integrate client updates.
