Ethereum’s Glamsterdam upgrade goes live on Sepolia, raising the block gas cap to nearly 200 million

Ethereum’s Glamsterdam upgrade was activated on the Sepolia testnet on Tuesday, according to CoinDesk, lifting the block gas cap from about 60 million to nearly 200 million. The change represents an increase of more than threefold and marks an early public test of the network’s new capacity settings. A review of more than 25 consecutive test blocks found actual gas usage ranged from roughly 52 million to 92 million, or about 26% to 46% of the available limit. None of the sampled blocks reached full capacity. The upgrade also changes how gas is charged for certain tasks and adjusts fees tied to data storage. That means developers may need to retest applications that rely on specific assumptions about gas costs. The next public testnet, Hoodi, is tentatively scheduled to launch on Oct. 27, while an activation date for Ethereum mainnet has not yet been set.
