Glamsterdam Upgrade Moves to Hoodi Testnet with Gas Limit Increase
Image: Ethereum FoundationThe Glamsterdam network upgrade is scheduled to activate on the Hoodi testnet at epoch 132,352 on October 26, 2026. The upgrade will raise Hoodi's gas limit from 60 million to 200 million, approximately 3.3x its previous level. Glamsterdam combines the Amsterdam execution layer upgrade with the Gloas consensus layer upgrade. The changes include enshrined proposer-builder separation, block-level access lists, and adjusted gas accounting. No mainnet activation date has been set.
Key points
- Glamsterdam combines Amsterdam execution layer upgrade with Gloas consensus layer upgrade.
- Upgrade includes enshrined proposer-builder separation and block-level access lists.
- No mainnet launch date or activation schedule has been set by the Ethereum Foundation.
Why it matters
The gas limit increase gives developers a chance to examine Ethereum's layer-one capacity under revised rules. Results from Hoodi will help evaluate client behavior before any mainnet activation.
What's unclear
The Ethereum Foundation has not set a mainnet launch date or activation schedule for Glamsterdam.
It is unclear whether the 200 million gas limit will remain the final setting or change before mainnet.
