[Ethereum Foundation to Activate Glamsterdam Upgrade on Sepolia Testnet on October 6] Foresight News reports that the Ethereum Foundation has announced the Glamsterdam network upgrade will be activated on the Sepolia testnet at 21:53:36 Beijing time on October 6, 2026 (epoch 353,024, slot 11,296,768). The activation time for Hoodi and the mainnet has not yet been determined. This upgrade integrates the execution layer Amsterdam and the consensus layer Gloas, with core improvements including: built-in proposer-builder separation (ePBS, EIP-7732), formally incorporating block proposing and building into the protocol; block-level access lists (BALs, EIP-7928), supporting parallel state reading and transaction validation; adjustments to gas pricing to more accurately reflect execution and state growth costs (EIP-8037, EIP-8038, etc.). Node operators must update their execution layer and consensus layer clients before activation. Relevant client versions have been gradually released, and a detailed compatibility list can be found in the official announcement. Mainnet users and ETH holders do not need to take any action at this time.
