Ethereum Glamsterdam Upgrade to Deploy ePBS and Block Access List, Boosting Throughput and Censorship Resistance

Ethereum's forthcoming Glamsterdam upgrade, slated for the first half of 2024, is set to significantly enhance the network's execution layer. This major overhaul will introduce enshrined Proposer-Builder Separation (ePBS) via EIP7732, moving relay-based block separation directly into the core protocol. Concurrently, the upgrade will deploy the Block Access List (BAL), enabling block builders to pre-declare transaction-affected accounts and storage slots. These innovations are designed to streamline MEV-driven block building, reduce censorship risks, and improve transaction throughput by allowing parallel verification. Additional changes include gas fee repricing, aiming to lower typical user costs while expanding network capacity and reshaping staking income dynamics.
