The Ethereum Foundation (EF) appoints Will Corcoran, Kev Wedderburn, and Fredrik as the new co-leads of its Protocol Cluster. This core technical unit manages the network’s long-term roadmap and coordinates the upcoming Glamsterdam hard fork, which focuses on scalability and security enhancements.
- The Ethereum Foundation appoints Will Corcoran, Kev Wedderburn, and Fredrik to lead the Protocol Cluster as several veteran developers depart.
- This new technical trio manages the 2026 Glamsterdam hard fork to integrate massive zero-knowledge virtual machine proving and scalability enhancements.
- Transitioning away from Tim Beiko and Barnabé Monnot signals a strategic shift toward ZK-centric expertise during a high-stakes protocol reorganization.
The Foundation confirmed the transition Monday, marking a significant shift in the personnel responsible for Ethereum’s Layer 1 development and Layer 2 coordination. Corcoran, Wedderburn, and Fredrik replaced outgoing veterans Barnabé Monnot and Tim Beiko, who guided the team through several years of protocol refinements. Alex Stokes, another central figure in recent upgrades, initiated a planned sabbatical from the organization.
The handover occurred at a critical juncture for the ecosystem as developers finalized the technical specifications for Glamsterdam. The incoming leadership trio brought specialized expertise in zero-knowledge virtual machine (zkVM) proving and zkEVM development. These technical backgrounds aligned with Ethereum’s strategic move toward a more ZK-centric scaling roadmap. The Foundation described the appointments as a way to integrate fresh perspectives while maintaining the momentum established by the previous leadership.
The Protocol Cluster functioned as the primary organizational hub for Ethereum’s core research and development. The team oversaw critical areas such as transaction throughput, Maximum Extractable Value (MEV) handling, and network efficiency. An internal reorganization preceded the leadership change, intended to streamline the team’s decision-making process and align it with 2026 strategic priorities.
Outgoing leads Monnot and Beiko served during a period that saw the successful execution of several major hard forks and the maturation of the Layer 2 landscape. Their departure represented the end of an era for the Protocol Cluster’s formative years. The Foundation emphasized that the transition plan sought to ensure continuity for the Glamsterdam upgrade cycle, which remained on schedule.

The new co-leads began their tenure by overseeing the final testing phases of these features. Their roles involved deep coordination with various client teams and independent researchers who contributed to the Ethereum codebase. By positioning experts in zkVM and protocol security at the helm, the Foundation signaled a commitment to the next phase of the network’s evolution.
Chain Street’s Take
The leadership transition within the Protocol Cluster signals a strategic pivot toward ZK-infrastructure expertise as Ethereum prepares for the Glamsterdam upgrade. The departure of veterans like Tim Beiko and Barnabé Monnot suggests an intentional refresh of the core development team to meet the scaling demands of the 2026 roadmap. By appointing co-leads with backgrounds in zkVM and protocol security, the Foundation is aligning its human capital with a technical future that prioritizes zero-knowledge proofs. This reorganization moves beyond simple personnel management, placing specialized engineers in control of the network’s most critical coordination hub during a high-stakes upgrade cycle.
