Two senior researchers, Carl Beek and Julian Ma, are leaving the Ethereum Foundation, adding to a wider turnover cycle that has raised questions about institutional continuity around Ethereum’s core protocol roadmap. Beek’s final day is set for May 29 after seven years at the Foundation, while Ma is exiting after roughly four years of work on censorship resistance, cross-layer systems and scaling research.
The departures matter because both researchers were tied to technically sensitive workstreams. Beek contributed to early Beacon Chain design and the KZG ceremony, while Ma worked on FOCIL, cross-layer bridge algorithms and faster confirmation mechanisms for Layer 2-to-mainnet flows.
Life Update: I have decided to leave the Ethereum Foundation. I’m very grateful to have worked with so many talented and inspiring people on an incredibly important project over the past four years.
I’m proud of the work we’ve done. Here are some of my personal highlights:

Core Protocol Knowledge Leaves During a Roadmap Push
Beek’s work connected directly to Ethereum’s proof-of-stake transition and related consensus infrastructure. His exit removes a contributor with deep context across Beacon Chain design, cryptographic ceremonies and protocol upgrades, areas where continuity matters for specifications, testing and coordinated deployment.
Ma’s work sat closer to censorship resistance, mechanism design and cross-layer execution. His contributions included EIP-7805, known as FOCIL, and a Fast Confirmation Rule that shortened Layer 2-to-mainnet bridging confirmation times to about 13 seconds, making his departure relevant to both protocol resilience and L2 user experience.
After 7 incredible years, I've decided that Friday May 29th will be my last day at the Ethereum Foundation.
I'm humbled by the projects I got to work on along the way: from the KZG ceremony, to helping architect the early design of the Beacon Chain, and a lot in between. At the…

The exits follow other high-profile departures and pauses inside the Foundation. Some names include Barnabé Monnot, Tim Beiko, Trent Van Epps, Josh Stark and Alex Stokes, with community scrutiny intensifying as the Foundation works through internal restructuring.
That turnover creates a practical coordination test. Ethereum’s development model is decentralized, but handoffs around consensus primitives, proof systems and bridge mechanics still depend on institutional memory held by individual researchers and maintainers.
Stewardship Model Faces an Execution Test
The Foundation has been reframing its role from ecosystem “owner” toward long-term steward, emphasizing research, public goods and decentralization. Staff departures now test whether independent teams, peer maintainers and external research groups can absorb roadmap responsibilities without slowing delivery.
The immediate concern is not that Ethereum development stops. The concern is whether tightly coupled workstreams such as Glamsterdam, Hegota and Verkle Trees retain enough continuity across specification, client implementation, testing and deployment coordination.
For infrastructure providers, custodians and Layer 2 teams, staffing changes matter because roadmap delays can affect client upgrade timelines, bridge behavior, settlement assumptions and operational planning. Protocol-level uncertainty becomes an input into release calendars and risk models.
Community scrutiny is likely to remain focused on transparency, succession planning and decision-making inside the Foundation. If the stewardship model is working, departures should be absorbed through clear handoffs and distributed ownership rather than creating bottlenecks around specific individuals.
The operational priority is monitoring release schedules, client-team communications and research ownership for major upgrades. The exits of Beek and Ma do not invalidate Ethereum’s roadmap, but they raise the bar for visible coordination and continuity as the Foundation decentralizes its role.
