COINOTAG News reports on December 21 that, after the Fusaka upgrade and lower node costs, Ethereum developers have initiated Glamsterdam planning for a 2026 launch. The name reflects two concurrent upgrades across Ethereum’s core layers: the Execution Layer will implement the Amsterdam upgrade, while the Consensus Layer will deploy the Gloas upgrade. Central to Glamsterdam are the proposer-builder separation (ePBS) and block-level ACLs, designed to curb MEV manipulation and abuse, and improve block production fairness. The plan signals a security-driven shift to enhance efficiency for operators and users alike.

From a technical perspective, ePBS isolates proposer and builder roles to reduce cross-layer collusion, with ACLs enforcing permissioning without sacrificing throughput. The rollout prioritizes robust finality, reduced latency, and sustainable validator incentives. By targeting MEV risk mitigation within the dual-layer upgrade, Glamsterdam aims to bolster network resilience, preserve asset liquidity, and align Ethereum’s roadmap with broader decentralization objectives.
