Ethereum’s Glamsterdam upgrade is scheduled for Hoodi, a test network, on Oct. 26, 2026, at 17:42:48 UTC, giving its node operators a deadline to upgrade software. The test pairs changes to block production and validation with a scheduled 200 million gas target.
The Ethereum Foundation’s Oct. 16 announcement fixes the next testnet deployment after Glamsterdam’s Oct. 6 activation on Sepolia. Mainnet timing remains undecided. ETH holders and mainnet operators have no action to take as a result of this Hoodi announcement.
All Hoodi operators must update their execution and consensus clients before activation. Validators must update both the beacon node and validator client, and review new duties, builder-tooling compatibility and gas-limit settings to follow the upgraded testnet.
