Ethereum Foundation Core Member Josh Stark Announces Departure
Josh Stark, a core member of the Ethereum Foundation, announced his departure after five years of service, officially stepping down at the end of April. Stark joined the Foundation in 2019, initially working in the special projects team before moving into leadership, collaborating with Foundation Chair Aya Miyaguchi, Ethereum founder Vitalik Buterin, and co-executive directors Hsiao-Wei Wang and Bastian Aue. He is one of the most prominent public figures of the Foundation, having led the transition from proof-of-work to proof-of-stake during The Merge, as well as subsequent upgrades like Dencun, Fusaka, and Pectra.
During last year's leadership restructuring, Stark was appointed co-manager of the board and recently became co-chair of the "Trillion Dollar Security" initiative. Last month, he co-authored an Ethereum strategy blog with Josh Rudolf and Julian Ma, discussing the relationship between mainnet scalability and the Layer 2 ecosystem. He stated that he has not planned for the future and just wants to take a break to spend time with family and friends. On the same day, Trent Van Epps also announced his departure from the Foundation to fully commit to his creation, Protocol Guild. Earlier, Tomasz K. Stańczak had resigned from his position as co-executive director at the end of February this year.

Josh Stark's departure continues the trend of leadership changes at the Ethereum Foundation leading into 2025-2026. From being a core participant in The Merge to co-chairing the Trillion Dollar Security initiative, his five-year contributions focused on upgrade coordination and external communication. His exit, alongside Trent Van Epps transitioning to Protocol Guild, reflects the Foundation's shift from centralized leadership to a more decentralized ecosystem funding model, with core developer incentives gradually moving to independent organizations.
This personnel change corresponds to the institutional inertia adjustment in Ethereum's governance structure. The Foundation is refocusing its strategic emphasis on mainnet scalability and cypherpunk values while facing talent retention pressures: high-value developers are more easily attracted to independent projects or higher compensation opportunities as the ecosystem matures. This flow accelerates the redistribution of power and resources from within the Foundation to external public goods organizations like Protocol Guild, reducing the control weight of a single entity over the evolution of the core protocol.
In a longer historical cycle, such waves of departures continue the migration path of open-source blockchain projects from early heroic leadership to professionalized, distributed coordination. Technological substitution and Layer 2 ecosystem expansion have made mainnet security and scalability a fundamental constraint of trillion-dollar assets, with the Foundation adapting to this scale change through leadership turnover and external funding mechanisms, while also highlighting the ongoing redistribution of wealth among protocol infrastructure, developer incentives, and application layers.
