Aya Miyaguchi announced today she will transition from Executive Director to President of the Ethereum Foundation (EF), a decision she 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.
