Glamsterdam Planning

Jul 29, 2025 | Updated Jul 29, 2025

Glamsterdam planning refers to the ongoing process of determining which improvements will be included in Ethereum's Glamsterdam upgrade.

What Is Glamsterdam Planning?

Glamsterdam planning is the current phase where Ethereum core developers are discussing and selecting which Ethereum Improvement Proposals (EIPs) will be included in the Glamsterdam hard fork, scheduled for 2026. Named from an amalgamation of “Gloas” (a star name following Ethereum’s naming convention for consensus layer upgrades) with “Amsterdam” (referencing the Devconnect city), this upgrade follows the Fusaka upgrade and represents the next step in Ethereum’s continuous evolution toward greater scalability, efficiency, and user experience.

The planning process involves Ethereum core developers, researchers, and community members evaluating proposed improvements across various areas of the network. Unlike previous upgrades that focused heavily on specific themes like The Merge’s transition to proof-of-stake or data availability improvements, Glamsterdam planning encompasses a broader range of potential enhancements.

Key proposals under consideration include reducing Ethereum’s block time from 12 seconds to 6 seconds, further gas limit increases, additional Ethereum Virtual Machine (EVM) optimizations, and continued improvements to Layer 2 integration.

How Does Glamsterdam Planning Work?

The Glamsterdam planning process follows Ethereum’s established governance model, where core developers discuss proposals during regular AllCoreDevs meetings and gather community feedback before making final decisions. The planning phase involves evaluating the technical feasibility, security implications, and potential benefits of each proposed improvement.

Throughout this period, developers assess how different EIPs might interact with each other and with existing network infrastructure. They also consider the testing requirements, complexity of implementation, and the estimated timeline for each proposal. This helps ensure that the final upgrade bundle is both technically sound and achievable within reasonable timeframes.

The planning process emphasizes community input and developer consensus. Proposed features must demonstrate clear benefits while maintaining Ethereum’s security and decentralization principles. As proposals are refined and tested, some may be included in Glamsterdam while others might be deferred to future upgrades.
