Ethereum Foundation departures: Beek and Ma exit as Protocol Cluster shifts

Fresh Ethereum Foundation departures are drawing attention well beyond staffing news. Carl Beek and Julian Ma, two researchers tied to core protocol work, are both leaving the organization at a moment when Ethereum is pushing through major technical changes and internal leadership reshuffles.

The timing matters. Ethereum’s development model is broader than the foundation itself, but the Ethereum Foundation departures still carry weight because they involve people who worked on research areas central to scaling, cryptoeconomics, and the network’s long-term roadmap.

Carl Beek will leave the Ethereum Foundation on May 29 after seven years at the organization. Julian Ma is also exiting after about four years. Their departures land amid wider Protocol Cluster changes, adding to a year in which several high-profile transitions have already become public.

Two researchers are leaving the Ethereum Foundation

Beek’s final day is set for May 29, closing a seven-year run at the Ethereum Foundation. Over that period, he worked on core Ethereum research, including the Beacon Chain, one of the most important pieces of the network’s proof-of-stake era.

Ma is also leaving the foundation after about four years. His work focused on mechanism design, cryptoeconomics, and protocol scaling, areas that sit close to some of Ethereum’s hardest engineering and coordination problems.

These Ethereum Foundation departures are notable not just because two researchers are exiting at once, but because they come during active roadmap work. Ethereum is still moving through upgrades and broader protocol planning, which means continuity in research and execution is under sharper scrutiny.

That does not mean development stops. Ethereum relies on a wide set of contributors across client teams, independent researchers, and core developers. Still, when experienced foundation staff move on, people across the ecosystem tend to watch closely for signs of how responsibilities will shift.

What Beek and Ma worked on

Beek is closely associated with core Ethereum research and the Beacon Chain. That work helped shape the foundation for Ethereum’s move away from proof-of-work and into its proof-of-stake structure.

Ma’s portfolio touched several of Ethereum’s more technical policy and design questions. His work included mechanism design, cryptoeconomics, and protocol scaling, all of which influence how the network performs and how incentives hold together under pressure.

FOCIL, EIP-7805, and the Fast Confirmation Rule

He also highlighted two pieces of work in particular:

• FOCIL, also known as EIP-7805
• The Fast Confirmation Rule

FOCIL is aimed at improving censorship resistance through inclusion lists, a design intended to make it harder for block builders or validators to leave out transactions.

The Fast Confirmation Rule speaks more directly to user experience. Ma said it reduced bridging time between Ethereum Layer 2s and the mainnet to 13 seconds. That kind of reduction matters because delays in moving assets or messages across Ethereum-linked systems can shape how usable the network feels in practice, especially as Layer 2 activity becomes more important.

This is one reason the latest exits stand out. The work tied to these researchers was not abstract housekeeping. It touched both Ethereum’s infrastructure and the everyday speed and reliability users notice when they interact with the ecosystem.

How the foundation is reshaping Protocol Cluster leadership

The staff changes do not stop with Beek and Ma. Their exits add to several public departures and role changes at the Ethereum Foundation this year, particularly around the Protocol Cluster.

Barnabé Monnot, Tim Beiko, and Alex Stokes have also been part of the recent shift. The foundation said Monnot and Beiko are moving on soon, while Stokes is taking a sabbatical.

At the same time, the Ethereum Foundation said new Protocol Cluster leads will be Will Corcoran, Kev Wedderburn, and Fredrik.

That leadership handoff is important because the Protocol Cluster sits close to Ethereum’s core technical direction. With roadmap work continuing around Glamsterdam, Hegota, FOCIL, Verkle Trees, and related scaling efforts, the new leads are stepping in during a period when deadlines, coordination, and technical credibility all matter more.

Why these Ethereum Foundation departures matter for the roadmap

The immediate question raised by the Ethereum Foundation departures is not whether Ethereum can keep building. The network has long depended on a decentralized development culture rather than a single institution.

The more meaningful question is how smoothly the foundation can maintain momentum while experienced researchers and coordinators rotate out. In a system as complex as Ethereum, institutional knowledge matters. Research handoffs, protocol priorities, and internal coordination can shape how quickly ideas move from proposal to implementation.

That is why the Protocol Cluster changes deserve as much attention as the departures themselves. New leadership can steady the process, but it also becomes a test of execution. The foundation has said Ethereum’s roadmap continues despite the staffing changes, and for now the focus shifts to whether that continuity holds as technical work moves forward.

For the broader Ethereum community, this is less a story about a sudden break than a stress test for succession. Ethereum has spent years building beyond any one team or person. Moments like this show whether that structure is strong enough to absorb turnover without slowing the network’s next phase.
