Ethereum Foundation in Turmoil: Why Key Developers Are Leaving in Droves

Key Takeaways

• The Ethereum Foundation faces continued talent drain as Carl Beek and Julian Ma announce resignations, continuing a pattern of departures spanning several months.
• Previous exits feature prominent names like Tomasz Stańczak, Barnabé Monnot, Tim Beiko, Alex Stokes, and Trent Van Epps.
• A controversial internal mandate was released in 2025, establishing CROPs values and attempting to clarify the Foundation’s ecosystem role.
• Reports emerged that employees were required to sign a loyalty commitment tied to the new mandate, sparking backlash.
• The ongoing exodus has prompted widespread discussion about leadership, organizational direction, and governance challenges.

The nonprofit organization behind Ethereum is experiencing another round of significant personnel losses. Carl Beek and Julian Ma both revealed their planned exits on Monday, continuing a troubling trend of departures that has captured the crypto industry’s attention.

Beek’s resignation marks the end of a seven-year tenure. His primary focus centered on developing the Beacon Chain, a crucial component that enabled Ethereum’s historic transition to proof-of-stake in 2022. His final day is scheduled for May 29.

Ma’s departure concludes approximately four years with the organization. His portfolio encompassed mechanism design, cryptoeconomics research, and protocol optimization efforts. Among his achievements, he contributed to EIP-7805, designed to enhance censorship resistance capabilities, and spearheaded initiatives that reduced Layer 2 to mainnet bridging times to just 13 seconds.

These resignations extend an already substantial list of personnel changes. In February, Tomasz Stańczak resigned from his position as co-executive director after serving less than twelve months. Josh Stark’s departure followed in March, ending a seven-year association.

Additional high-profile exits encompass Barnabé Monnot and Tim Beiko, both recognized figures in Ethereum’s core development ecosystem. Trent Van Epps, instrumental in establishing Protocol Guild—a funding mechanism supporting core developers—also departed in recent months. Alex Stokes, previously serving as co-lead of the Protocol cluster, began a sabbatical earlier this month.

Last June witnessed Péter Szilágyi’s exit after nearly ten years with the organization. His legacy includes creating Geth, which remains the dominant Ethereum execution client.

Internal Transformation at the Ethereum Foundation

Facing mounting community pressure, the Foundation initiated a comprehensive reorganization throughout 2025. Community members had voiced frustration regarding slow decision-making processes, insufficient transparency, and inadequate ecosystem support amid intensifying blockchain competition.

The restructuring brought technically-oriented co-executive directors into leadership positions. Additionally, Vitalik Buterin increased his public engagement, providing more detailed communication about Ethereum’s development trajectory.

The organization released a fresh mandate earlier this year, defining its CROPs principles—Censorship resistance, Open source, Privacy, and Security. The document explicitly positioned the Foundation as one stakeholder among many, rejecting any ownership claims over Ethereum itself.

Controversy erupted, however, when reports surfaced that employees faced pressure to sign loyalty commitments aligned with the mandate. Additional criticism stemmed from references to the Milady online community included within the document.

The Foundation declined to provide comment when contacted.

What Happens Next

The organization has publicly committed to diminishing its centralized influence as the Ethereum ecosystem matures and diversifies. How these ongoing departures will impact that strategic shift remains an open question.
