Ethereum's Glamsterdam upgrade, scheduled for H2 2026, is the largest network upgrade since The Merge. Key improvements include built-in PBS (ePBS) to eliminate relay dependence, block-level access lists (BALs) for parallel execution and efficient syncing, and gas repricing to better reflect computation and state storage costs. The upgrade aims to enhance mainnet performance, stabilize fees, and maintain decentralization.

Ethereum Glamsterdam Upgrade: The Largest Since The Merge

Ethereum is set to undergo the Glamsterdam upgrade in the second half of 2026, the most significant network upgrade since The Merge. Three core changes stand out:

Built-in PBS (ePBS): Eliminates reliance on relayers by integrating proposer and builder roles, reducing centralization risks and potential MEV manipulation.
Block-Level Access Lists (BALs): Enable parallel execution and more efficient syncing, boosting transaction processing throughput and reducing block validation latency.
Gas Repricing: Adjusts gas costs to more accurately reflect computation and state storage, helping stabilize fees and optimize resource allocation.

The upgrade aims to improve Ethereum mainnet performance, stabilize user fees, and preserve decentralization, benefiting both individual users and validators.
