Ethereum’s Glamsterdam Upgrade Goes Live on the Sepolia Testnet
Ethereum’s eagerly anticipated Glamsterdam upgrade reached an important milestone on October 6, 2026, with its launch on the Sepolia testnet, bringing developers closer to activating it on the mainnet. The upgrade aims to improve scalability, transaction-processing efficiency, and overall network performance through a set of key changes, including enshrined Proposer-Builder Separation (ePBS) and Block-Level Access Lists (BALs). These enhancements are designed to support transaction processing, streamline block validation, and improve the use of network resources. After the upgrade launches on Sepolia, developers will assess its activation on the Hoodi testnet before setting a date for its mainnet launch. Glamsterdam marks another important step in Ethereum’s ongoing efforts to advance its infrastructure and support the network’s long-term growth.
