Ethereum Unveils Glamsterdam Upgrade Plan for 2026

Ethereum is set to undergo its next major upgrade, dubbed Glamsterdam, which aims to improve the network's efficiency, scalability, and usability. Scheduled for the second half of 2026, Glamsterdam will build on previous upgrades like The Merge, Dencun, and Pectra.

The upgrade doesn't create a new Ethereum but rather improves upon the existing network by making it more efficient, faster, and capable of handling greater activity. This is necessary due to the increasing number of users, transactions, and blockchain applications, which put pressure on the network's capacity.

Glamsterdam will bring two major updates: Enshrined Proposer-Builder Separation (ePBS) and Block-Level Access Lists (BAL). ePBS separates the roles in block creation, making the process more structured and efficient. BAL helps the network predict which data will be accessed during block processing, allowing it to prepare for execution in advance.

The upgrade is designed to improve transaction processing efficiency, increase capacity, and make the network faster. This should result in a smoother user experience, especially during peak traffic. Additionally, Glamsterdam's impact on developers and decentralized applications (dApps) will be significant, enabling them to build more complex applications that require multiple processes and data simultaneously.
