Ethereum is planning to launch the Glamsterdam upgrade in the second half of 2026, marking the largest network upgrade since The Merge. Key features include embedded PBS (ePBS) to eliminate relay dependency, Block-level Access Lists (BALs) for parallel execution and efficient synchronization, and gas repricing to accurately reflect computation and state storage costs. The upgrade aims to enhance mainnet performance, stabilize fees, and maintain decentralization.

Glamsterdam Upgrade Highlights

Ethereum's upcoming Glamsterdam upgrade, scheduled for the second half of 2026, is positioned as the most significant network overhaul since The Merge. The core components include:

Embedded PBS (ePBS): Eliminates reliance on relays by integrating proposer-builder separation directly into the protocol, strengthening decentralization and security.
Block-level Access Lists (BALs): Enable parallel execution and more efficient state synchronization, boosting transaction throughput.
Gas Repricing: Revises the gas cost model to more accurately reflect computational effort and state storage impact, reducing fee volatility.

The overall objective is to improve Ethereum mainnet performance and user experience without compromising the decentralized ethos. The upgrade is currently in the technical specification phase and is expected to incorporate multiple EIPs. Further details can be found in the official announcement.
