The Ethereum Foundation has experienced a devastating wave of departures in 2026, with eight senior researchers quitting the organization in a single calendar year. According to Phemex Blog, five of these resignations occurred in May alone, including Carl Beek after seven years and Julian Ma after roughly four years on the protocol R&D team. The departures span research, governance, and operations roles, with tenures ranging from four to seven years. The Protocol Cluster team, responsible for Ethereum protocol research, has now lost contributors across every layer it covers, including Barnabé Monnot, Tim Beiko, Trent Van Epps, Alex Stokes, Josh (operations and writing lead), and former co-executive director Tomasz Stańczak. The latest departures include co-executive director Tomasz Stańczak after just 11 months in the role, adding to the broader wave of exits that has included prominent contributors such as Carl Beek, Julian Ma, and Alex Stokes. Two prominent researchers resigned from the Ethereum Foundation on Monday, increasing the number of high-profile departures to eight in recent months, with Key researcher and project manager Josh Stark announcing his departure in April on the same day that Ethereum Foundation contributor Trent Van Epps did the same.
The departures represent the second-order effect of Vitalik Buterin's 2025 reorganization that explicitly changed the Ethereum Foundation's role from top-down roadmap ownership to a focused research and grants hub. As reported by Phemex Blog, execution moved outward to independent client teams (Geth, Nethermind, Besu, Erigon, Reth, Lighthouse, Prysm, Teku, Lodestar) and to standalone organizations that already employ many former EF researchers. The new mandate de-emphasizes individual researcher prominence in favor of a flatter, grants-funded model, with the replacement structure naming Will Corcoran, Kev Wedderburn, and Fredrik as new leads who carry less public profile than their predecessors. Several departing researchers have already announced moves to L2 teams, independent research organizations, or their own ventures, with the protocol still benefiting from their work through client teams and standards bodies, though the Foundation no longer employs them directly.
Crypto commentator Andy, co-founder of the Rollup podcast, wrote on X: "What's happening at the EF?" as community members openly questioned the organization's direction and leadership structure. As reported by CoinDesk, others echoed similar frustrations, with Joon Ian Wong, a prominent figure in the crypto community events space, writing: "Why can't the EF just be transparent about things?" The criticism reflects growing tensions between Ethereum's decentralized ethos and community demands for greater transparency and accountability from the network's main steward, which plays a central role in funding research, coordinating upgrades and stewarding development of the world's second-largest blockchain by market capitalization. The EF has long functioned as a kind of shadow ministry of Ethereum — coordinating research, funding core devs, and managing a treasury loaded with ETH, but its inner workings remain opaque by design.
Despite the massive departures, Ethereum's protocol operations remain functional with Glamsterdam, the next hard fork targeted for H1 2026, still on schedule around June. According to Phemex Blog, Glamsterdam enshrines Proposer-Builder Separation (ePBS) and introduces Block-Level Access Lists (BALs), the foundations for parallel execution and the path toward 10,000 TPS on L1. The BlackRock ETHB staking ETF, which launched in March 2026, continues to take inflows with stable validator counts, while Layer 2 activity across Base, Arbitrum, Optimism, Linea, and Scroll has not paused on EF news cycles. The H1 2026 target around June still holds with work scoped before the May departures, as client teams outside the EF handle actual implementation of the upgrade specifications. The protocol roadmap is decoupled from EF headcount in a way that did not exist five years ago, with the actual leading indicator being upgrade cadence and client-team independence rather than foundation staffing levels.
The institutional risks are becoming real on a 12-24 month horizon rather than immediate market catalysts, with concerns centered on hard-fork cadence and coordination capacity. As reported by Phemex Blog, if Hegota slips into 2027 and All Core Devs coordination visibly thins, the institutional risk becomes a real one, potentially stretching upgrade gaps from six to twelve months. The second risk is research direction, as without a strong EF research voice, the protocol's research agenda becomes whatever the loudest L2 teams and best-funded independent labs want it to be, removing a neutral coordinator from the process. The bear case involves the EF becoming a passive grants office while actual coordination work consolidates inside a single client team or moves to a parallel organization, which would meaningfully change the politics of who decides protocol direction. However, ETH holders should track upgrade cadence and client-team independence, not EF headcount, as the actual leading indicator for the network's continued innovation and community trust.
