ZEC $1,059 Ethereum plans 3.3x gas limit rise on Hoodi testnet
Glamsterdam is set to lift Hoodi's gas limit from 60 million to 200 million on October 26, with no mainnet date yet announced.
Key takeaways
- Hoodi activates October 26. The gas limit moves from 60 million to 200 million at the same fork epoch as Glamsterdam.
- Sepolia went first. Sepolia activated the upgrade on October 6, and Hoodi follows as the final testnet.
- 300 million is not confirmed. Wahrstätter described 300 million gas as a possible longer-term target rather than a Glamsterdam setting.
What happened
Ethereum's Glamsterdam upgrade is scheduled to activate on the Hoodi testnet at epoch 132,352, slot 4,235,264, which the report gives as October 26, 2026, 17:42:48 UTC.
The proposed change takes the gas limit from 60 million to 200 million, a roughly 3.3-fold increase. Sepolia activated the upgrade on October 6, and Hoodi is the final testnet before mainnet, according to Ethereum researcher Toni Wahrstätter.
The Ethereum Foundation identifies enshrined proposer-builder separation and block-level access lists as core parts of the upgrade. The report also lists gas pricing changes intended to better reflect execution and state growth.

Why it matters
The gas limit sets a ceiling on the computation each block can contain. A higher cap could leave room for more transactions or more complex contract activity when demand exists, but it does not promise faster confirmations or a fixed transactions-per-second figure.
A larger gas target may add pressure to node hardware, storage and bandwidth. Block-level access lists record the accounts and storage locations a block touches, which could help clients read state and validate transactions in parallel.
Wahrstätter suggested 300 million gas could be a realistic next step after the 200 million target, but that figure is a potential future milestone rather than a confirmed part of Glamsterdam.
What is still unclear
- The Ethereum Foundation has not set a mainnet launch date or activation schedule.
- Ethereum developers say the mainnet activation time will be announced once client teams decide it.
Questions readers ask
When will Glamsterdam activate on Hoodi?
The upgrade is scheduled for epoch 132,352, slot 4,235,264, which the report gives as October 26, 2026, 17:42:48 UTC.
How much will Ethereum's gas limit increase?
The proposed change takes the limit from 60 million to 200 million, a roughly 3.3-fold increase.
Is 300 million gas part of Glamsterdam?
No. Researcher Toni Wahrstätter has discussed 300 million gas as a possible longer-term target, not a confirmed Glamsterdam setting.
When will Glamsterdam reach Ethereum mainnet?
The Ethereum Foundation has not set a mainnet launch date or activation schedule. Developers say the mainnet activation time will be announced once client teams decide it.
