Ethereum's upcoming upgrade, Glamsterdam, is set for a 2026 launch, aiming to tackle MEV and boost network efficiency. The upgrade may include enshrined Proposer-Builder Separation (ePBS) and Block-level Access Lists (BALs). These changes could streamline transaction execution and reduce validator hardware needs. The Fusaka upgrade in December 2025 laid the groundwork by expanding blob capacity and cutting node costs. Developers are still finalizing which Ethereum Improvement Proposals to include. Public testnets are expected in early 2026, with a mainnet rollout to follow. What is the timeline for this upgrade? Testing and audits will determine the final scope.
