Josh Stark, a long-standing member of the Ethereum Foundation leadership team, has announced he will step down after five years at the organization. The departure comes as the Foundation continues a broader restructuring effort initiated by Vitalik Buterin.
Stark confirmed the decision in a public statement, noting that he made the choice in early March and plans to complete his transition by the end of April. He did not cite a specific reason for leaving and stated he has no immediate professional plans.
After 5 years on the @ethereumfndn leadership team, I’ve decided to step away and pass the torch. I made this decision in early March, and will wrap up my work at the end of April. I’ve made no plans for the future, other than taking a long break to reset and spending time with…

A high-profile departure during structural change
Stark’s exit marks one of the most visible departures from the Foundation since leadership changes began taking shape in 2025. He held a central role as both a researcher and project manager, with his position listed among a small group categorized as “Management” in the organization’s internal structure.
His departure follows another recent resignation from contributor Trent Van Epps, which adds to a period of transition inside the Foundation.
The timing aligns with an ongoing reorganization effort led by Buterin. The Ethereum co-founder confirmed that changes to the Foundation’s leadership structure have been underway for nearly a year. Some adjustments have already been implemented, while others remain in progress.
We are indeed currently in the process of large changes to EF leadership structure, which has been ongoing for close to a year. Some of this has already been executed on and made public, and some is still in progress.

What we're trying to achieve is primarily the following…
Vision for a restructured Foundation
Buterin outlined several priorities behind the restructuring. He emphasized the need to strengthen technical expertise within leadership and improve communication between the Foundation and the broader Ethereum ecosystem, which includes developers, users, wallets, and layer-2 networks.
He also highlighted the importance of faster execution and stronger support for application builders. The Foundation aims to reinforce values such as privacy, open-source development, and censorship resistance, particularly at the application layer.
“We are indeed currently in the process of large changes to EF leadership structure,” Buterin stated.
He added that the organization seeks to “bring in fresh talent, improve execution ability and speed” while maintaining its foundational principles.
At the same time, Buterin made clear what the Foundation will not pursue. He rejected the idea of shifting toward political lobbying or aligning with powerful regulatory interests, particularly in the United States. He also ruled out turning the Foundation into a centralized authority within the Ethereum ecosystem.
“These things aren't what EF does and this isn't going to change. People seeking a different vision are welcome to start their own orgs,” he said.
Reflecting on Ethereum’s early challenges
In his statement, Stark reflected on the evolution of Ethereum and the challenges the ecosystem has faced since its inception. He pointed to moments when the project’s viability came into question, including skepticism around its initial launch, decentralized finance, and the transition to Proof of Stake.
“The Ethereum ecosystem has reliably done things the world told us were impossible,” Stark said. “It is easy to forget how much real fear and doubt there was that Ethereum would never launch, that decentralized finance (DeFi) would never work, or that Proof of Stake would never ship.”
He framed these experiences as evidence that complex technical and social challenges can be overcome through sustained effort and collaboration.
“The lesson is not that our success was guaranteed and the doubters are always wrong, but that truly wicked problems can be overcome when great people make an extraordinary effort. You must make an extraordinary effort.”
Leadership shifts continue into 2026
The Foundation introduced new leadership roles in March 2025, appointing Hsiao-Wei Wang and Tomasz Stańczak as co-directors. Stańczak later stepped down from the position in February 2026, while Wang remains part of the management board.
These changes reflect an ongoing attempt to balance continuity with renewal inside one of the most influential organizations in the blockchain sector.
Stark’s departure adds another layer to that transition. His remarks suggest a personal decision shaped by the intensity of the role and the desire to step back after years of involvement at a critical level.
A pause, not a pivot
Stark described his time at the Foundation as a formative experience. He emphasized the impact of working alongside key figures such as Buterin and executive director Aya Miyaguchi, as well as other contributors across the ecosystem.
“Working for Ethereum at the Ethereum Foundation has been a great honour,” he said. “This journey has been a gift.”
His next steps remain undefined. The statement points to a period of rest rather than a transition into a new role. That pause stands in contrast to the broader momentum inside the Foundation, which continues to evolve its structure and priorities.
