The upgrade aims to enhance Layer 1 scaling with proposals like Enshrined Proposer-Builder Separation and Block-Level Access Lists.
Ethereum core developers have initiated full-scale testing of the Glamsterdam upgrade on private developer networks. This marks the final phase before the codebase is frozen and deployed to public testnets in 2026.
The upgrade focuses on improving Layer 1 scaling through key Ethereum Improvement Proposals (EIPs), including Enshrined Proposer-Builder Separation (ePBS) and Block-Level Access Lists. These changes are designed to optimize network performance and efficiency.
Glamsterdam is positioned as the most significant planned upgrade for Ethereum in 2026, following extensive development and consensus among core teams.
