Glamsterdam Upgrade: Ethereum's Next Big Leap

The upcoming Glamsterdam upgrade, expected in H1 2026, is poised to bring significant network overhauls to Ethereum, focusing on core protocol fairness, efficiency, and block production, with a blend of changes to both the consensus and execution layers.

The top 3

  1. Top 3 Expected Benefits of Glamsterdam Upgrade: The Glamsterdam upgrade is expected to significantly increase Ethereum's gas limit target from 60M to 200M per block, aiming for throughput ambitions reaching up to 10,000 transactions per second (TPS) [34]. It also anticipates potential fee reductions of up to 78.6% and introduces Enshrined Proposer-Builder Separation (ePBS) to mitigate MEV-related centralization risks [34, 28].
  2. How Glamsterdam Fits Ethereum's Long-Term Vision: The Glamsterdam upgrade aligns with Ethereum's long-term vision by shifting attention to core protocol fairness and block production efficiency, strengthening the base layer [28]. It prioritizes decentralization and validator diversity over raw block speed competition, while also supporting cheaper Layer 2 rollups and enhancing censorship resistance [28].
  3. Major Challenges Ethereum Still Faces Post-Glamsterdam: Even after Glamsterdam, Ethereum still faces challenges including the full implementation of sharding for ultimate scalability, ongoing concerns about centralization due to staking pools and node distribution, and the inherent technical complexity of future upgrades that can introduce new bugs or vulnerabilities [26, 30, 40, 43].
