What Are the Highlights of Ethereum's Most Important Glamsterdam Upgrade This Year?
Ethereum's upcoming Glamsterdam upgrade, a major mid-year update, focuses on execution-layer improvements, building upon the data-layer enhancements of the previous Fusaka upgrade. The core features include ePBS (enshrined Proposer-Builder Separation) and BAL (Block Access List).
ePBS (EIP-7732) formally bakes the separation of block building and validation roles into the protocol, moving away from reliance on third-party relays. This aims to reduce trust assumptions, prevent centralization at the validator level, and improve network efficiency. BAL allows block builders to pre-declare which accounts and storage locations a block's transactions will access, enabling validators to prepare data and verify transactions in parallel, significantly boosting throughput.
Additional changes include gas fee re-pricing and multi-dimensional gas, which are expected to lower costs for average users while increasing overall network capacity (though potentially raising costs for some developers).
For stakers, the upgrade promises a clearer income model and greater block selection power, smoothing out MEV rewards. However, the full potential of ePBS is dependent on a future upgrade (Hegotá) to implement FOCIL (Fork Choice-Enforced Inclusion Lists), which would give validators a final tool to combat transaction censorship.
Potential challenges include the upgrade's high complexity, the risk of new forms of validator centralization, and the fact that toxic MEV (e.g., front-running) may persist, merely shifting elsewhere. Ultimately, Glamsterdam represents a significant step in Ethereum's commitment to decentralization, potentially increasing its trust and adoption.
