Ethereum Glamsterdam upgrade is scheduled to be October 6 on Sepolia testnet
PANews September 29 reported that the Ethereum Foundation announced that the Ethereum network upgrade Glamsterdam is scheduled for October 6 activation on Sepolia testnet at Beijing time 21: 53: 36, corresponding to epoch 353024、slot 11296768. The activation dates for Hoodi and mainnet have not yet been determined.Glamsterdam Combining the execution-layer Amsterdam upgrade with the consensus-layer Gloas upgrade, the key changes include built-in proposer-builder separation and block-level access lists to improve L1 throughput, as well as adjustments to gas pricing to better reflect the costs of execution and state growth. Node operators must update their execution-layer and consensus-layer clients before activation. Contracts that rely on fixed gas assumptions may require modification.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
This upgrade is initially planned to be activated on Sepolia the testnet rather than directly on mainnet. It involves both the execution layer and consensus layer, so node operators need to update both types of clients in advance; some contracts that rely on fixed gas assumptions may also need adjustment.
Why it matters to readers
The material states that the upgrade aims to improve L1 throughput and make gas pricing better reflect the costs of execution and state growth, so nodes and related contracts need to pay attention to compatibility.
Beginners should focus on distinguishing “testnet activation” from “mainnet activation”: the material currently provides only the planned timing for Sepolia, while the mainnet date remains undetermined.
Risks and unknowns
The material does not state the year to which October 6 it belongs.
The current material provides only PANews’ account and does not include a link to the Ethereum Foundation’s original announcement.
Sepolia Whether the activation will succeed as planned and how it will operate afterward cannot yet be confirmed.
The specific activation dates for Hoodi and mainnet have not yet been determined.
The material does not specify which contracts that rely on fixed gas assumptions need to be modified or how they should be modified.
