Ethereum validator patch clears Glamsterdam's 200M-gas Sepolia test
Ethereum's Glamsterdam upgrade is set to activate on the Sepolia testnet on October 6, raising the block gas limit to 200 million gas — one of the largest capacity increases the network has tested on a live testnet. A key validator client pushed a last-minute patch hours before the test to clear the way for the deployment.
- The upgrade brings built-in proposer-builder separation (ePBS), block-level access lists and gas pricing adjustments; mainnet timing is still to be confirmed.
- Developers warn that free test ether lets "fake" builders outbid real ones and withhold transaction payloads, which could stall the chain during testing.
- Client teams got about half the usual review time before the Sepolia deployment, adding pressure to the verification window.
