Ethereum Delays Glamsterdam’s October 26 Hoodi Upgrade
Ethereum has postponed Glamsterdam’s Hoodi activation to review EIP-8037’s contract interactions. No new testnet or mainnet launch date has been set.
Key Notes
- Ethereum has postponed Glamsterdam’s October 26 Hoodi testnet activation while developers review EIP-8037’s interaction with existing contracts.
- The revised configuration removes the planned 200 million gas-limit increase without reverting Hoodi’s block history.
- No replacement testnet or mainnet date is set, and Ethereum mainnet users and ETH holders need take no action.
Ethereum developers have postponed Glamsterdam’s October 26 activation on the Hoodi testnet while they investigate how EIP-8037 interacts with smart contracts already deployed on mainnet. No replacement date has been announced.
The Ethereum Foundation’s October 22 notice supersedes the earlier activation instructions. It concerns a test network, not an upgrade already running on Ethereum mainnet. ETH holders do not need to move funds or change wallets.
Gas Accounting Gets Another Review
The decision followed the ACDE #248 developer call. Its agenda included security concerns around EIP-8037 and EIP-8038, alongside the planned Hoodi deployment. Discussion of possible mainnet dates was preliminary; those candidates were not an approved activation schedule.
EIP-8037 changes the cost of creating persistent blockchain state, such as new accounts and storage entries. It separates state-creation charges from execution charges so that higher transaction capacity does not produce unchecked database growth.
The interaction matters because applications can rely on assumptions about how much gas remains after a contract calls another contract. Gas is Ethereum’s unit for metering computational work and other resources, rather than a fixed fee in dollars.
In an October 13 analysis, security firm ChainSecurity explained that the proposed accounting and repricing rules can change what happens after a failed call. A contract might have enough gas to record a permanent failure where it previously would have reverted the operation, potentially removing a retry opportunity.
ChainSecurity also cautioned that a gas budget sufficient under the old rules may be inadequate under the new ones. These are compatibility and security questions about proposed upgrade behavior; they are not evidence that Hoodi’s postponement resulted from a theft or a rollback of Ethereum mainnet.
The October 26 Configuration Is Removed
The old Hoodi schedule targeted epoch 132,352 at 17:42:48 UTC on October 26. The configuration changes remove both the Amsterdam execution-layer activation and the Gloas consensus-layer activation, together with the planned increase to a 200 million block gas limit.
Lodestar’s merged change corroborates the removal of the Gloas activation and the gas-limit entry. Unscheduling a future fork changes the rules clients are preparing to apply; it does not erase Hoodi’s existing blocks.
Hoodi operators need execution and consensus clients that reflect the postponement. Lodestar’s release notes warn that its preceding version still schedules Gloas at the old epoch and would leave affected nodes on a separate chain. Validator operators must also check their validator software and builder or relay configuration.
Glamsterdam’s Mainnet Date Remains Open
CoinScreamer’s earlier report covered the original Hoodi timetable and the upgrade’s two headline changes: enshrined proposer-builder separation, or ePBS, and block-level access lists.
The first brings proposer-builder coordination into Ethereum’s consensus rules. The second records the accounts and storage locations touched by a block, helping clients organize parallel reads and transaction validation. The Foundation’s original announcement presented both as foundations for increasing execution capacity.
That technical direction does not supply a new launch date. Developers will announce a revised Hoodi schedule separately, while a mainnet activation remains unassigned.
