Aya Miyaguchi Transition to President of Ethereum Foundation

Aya Miyaguchi announced today her transition from Executive Director to President of the Ethereum Foundation (EF), a decision made a year ago.

In her new role, Miyaguchi will focus on supporting EF’s institutional relationships and expanding the organization’s vision and culture more broadly.

> “Ethereum belongs to everyone precisely because it belongs to no one,” Miyaguchi wrote in her announcement. “Our culture of permissionlessness doesn’t just tolerate disagreement — it grows stronger through it.”

Miyaguchi emphasized that EF’s role has never been to control all aspects of Ethereum.

> “Our responsibility—our accountability—lies in upholding Ethereum’s values,” she stated. “Through both our actions and our non-actions, we are accountable for ensuring that Ethereum remains resilient, not just as a network, but as a broader ecosystem of people, ideas, and values.”

During her seven-year tenure at EF, Miyaguchi has overseen several key initiatives, including the promotion of client diversity, support for R&D interop retreats, and the coordination of development calls. She highlighted The Merge to Proof-of-Stake as a particular achievement that required “leadership without control, coordination without centralization.”

> “When I first discussed the possibility of transitioning to President with Vitalik a year ago, it was with the intention of continuing to nurture the unique culture of Ethereum, and serving as a voice to bridge the gap between Ethereum and the broader global community,” Miyaguchi wrote.
