According to BlockBeats, Ethereum developers have initiated plans for the 'Glamsterdam' upgrade, aiming for a 2026 launch following the successful Fusaka upgrade, which reduced node costs. The name 'Glamsterdam' combines two simultaneous upgrades on Ethereum's core layers. The execution layer, responsible for transaction rules and smart contracts, will undergo the Amsterdam upgrade, while the consensus layer, which coordinates validators and finalizes blocks, will experience the Gloas upgrade. The upgrade focuses on proposer-builder separation (ePBS) and block-level access control lists to minimize manipulation and abuse opportunities related to maximum extractable value (MEV).
