Ethereum to trial 200M gas limit in tonight's Sepolia "Glamsterdam" upgrade

Ethereum developers will roll out the Glamsterdam upgrade on the Sepolia testnet at 21:53 Beijing time tonight, lifting the per-block gas limit from about 60 million to 200 million, CoinDesk reported. The move is designed to gauge how the network performs with larger blocks and higher transaction throughput. Ahead of the activation, Ethereum validator client Prysm rushed out version 7.2.1 to address an issue in which the latest gas-limit setting had been left out. With the update, validators will automatically propose blocks at a 200 million gas limit. Nodes running older versions that haven't been manually reconfigured may continue enforcing the roughly 60 million limit, which could skew the test. The change is limited to Sepolia and does not affect Ethereum mainnet. Developers will use the results to assess whether validators can consistently handle larger blocks and to help set capacity parameters for any future mainnet rollout.
