Ethereum's Glamsterdam upgrade passes Sepolia rehearsal with testnet launch scheduled for October 6, raising gas limits and enabling parallel transaction processing.
Tech & Launches ·
Ethereum's Glamsterdam upgrade cleared testing milestones on Sepolia this week and will launch on the testnet October 6, raising the block gas limit to 200 million from 60 million to accommodate more transactions per block. The upgrade introduces block-level access lists that enable nodes to process unrelated transactions in parallel rather than sequentially, with Nethermind client tests verifying the mechanism's performance across 2,302 cases. These changes are designed to reduce fee volatility during periods of high demand, though the larger block size may increase operational costs for node operators.
