Ethereum Developers Target 2026 for Glamsterdam and Hegota Upgrades

Ethereum developers plan Glamsterdam in May 2026 to improve capacity and validator efficiency, followed by Hegota later in the year, continuing the network’s biannual upgrade cadence.

Summary

Ethereum developers have scheduled two major protocol upgrades for 2026. Glamsterdam, set for May, will focus on enhancing network capacity and validator efficiency, combining execution layer and consensus layer changes including ePBS and block-level ACL to combat MEV manipulation. A second upgrade, Hegota, is planned for later in 2026, aligning with Ethereum’s twice-yearly upgrade schedule.

Terms & Concepts
  • Execution layer: The part of Ethereum responsible for processing transactions and executing smart contracts (self-executing blockchain code).
  • Consensus layer: The component of Ethereum that coordinates validators and ensures agreement on the blockchain state.
  • Maximum extractable value (MEV): The profit validators can gain by reordering, including, or excluding transactions within a block.
