Hoodi

Ethereum developers have merged a fix for a flaw in the upcoming Glamsterdam upgrade that could have credited ETH intended for new validators to builders instead. No losses have been reported, and client teams must now implement the revised deposit rules before the upgrade can move closer to mainnet.

Ethereum developers have delayed the Glamsterdam upgrade on the Hoodi test network after security researchers raised concerns about proposed gas accounting changes. The issue could affect how existing smart contracts handle failed transactions, while no new Hoodi activation date has been announced.

Ethereum’s Glamsterdam upgrade has lifted Sepolia’s processing allowance from about 60 million gas to nearly 200 million gas as developers test higher-capacity block design. Early sampled blocks used only 26% to 46% of the available allowance, while a short finality period showed strong testnet participation.

Ethereum developers have confirmed key testing dates for the Glamsterdam upgrade while warning that disposable builder identities could disrupt Sepolia block production. The issue does not threaten mainnet funds, but it could complicate infrastructure testing before the upgrade moves closer to Ethereum activation.
