Ethereum Glamsterdam completes Devnet-11 drill, proposes gas limit increase to 200 million

The Ethereum Glamsterdam upgrade completed its Devnet-11 drill this week, successfully confirming blocks under new construction rules. The proposal aims to raise the block gas limit from 60 million to 200 million and introduce block-level access lists to enable parallel data fetching and transaction validation. The upgrade also extends block data propagation time from 2 seconds to 9 seconds. While the Nethermind execution client passed performance tests, the 200 million gas limit remains experimental and has not undergone adversarial stress testing. Deployment on the Sepolia testnet is tentatively planned for October 6.
