"The community needs to create an organization that's economically aligned with Ethereum and accountable to it." — Dankrad Feist, Former Ethereum Foundation Researcher
Nine senior contributors departed the Ethereum Foundation (EF) between February and May 2026, marking the steepest talent drain in the organization's 11-year history. Five left in May alone. The exits include Tim Beiko, who coordinated Ethereum's All Core Devs calls; Barnabé Monnot, co-lead of the Protocol Cluster; and Carl Beekhuizen, a seven-year veteran who helped architect proof-of-stake consensus.
The departures coincide with the EF's publication of a 38-page constitutional mandate on March 13, 2026, codifying what it calls the "CROPS" principles — censorship resistance, open source, privacy, and security — and a deliberate organizational contraction under the banner "Lean Ethereum." The Foundation's treasury stood at $970.2 million as of October 31, 2024, with annual spending capped at 15% of assets and a stated goal of reducing expenditure by 67% by 2030. ETH traded near $1,670 on June 4, 2026, down approximately 57% from its 2025 peak near $5,000.
The immediate protocol-level impact appears contained: the Glamsterdam hard fork remains on track for Q3 2026, and independent client teams — Geth, Nethermind, Besu, Erigon, Reth, and others — continue to ship code. The structural question is whether the Foundation's pivot from active coordinator to passive steward introduces coordination friction that compounds over successive upgrade cycles.
The following senior contributors exited the EF in 2026, according to reporting from CoinDesk, Phemex, and DeFi Prime:
| Name | Role | Tenure | Exit Date | |------|------|--------|-----------| | Tomasz Stańczak | Co-Executive Director | <1 year | Feb 13, 2026 | | Josh Stark | Operations & Communications Lead | 7 years | March 2026 | | Raúl Kripalani | P2P Networking Head | Multi-year | March 2026 | | Trent Van Epps | Protocol Guild Coordinator | ~5 years | April 10, 2026 | | Tim Beiko | All Core Devs Coordinator | Multi-year | May 2026 | | Barnabé Monnot | Protocol Cluster Co-Lead | Multi-year | May 2026 | | Alex Stokes | Consensus-Layer Researcher | Multi-year | May 2026 (leave) | | Julian Ma | Censorship-Resistance Researcher | 4 years | May 18, 2026 | | Carl Beekhuizen | PoS Consensus Architect | 7 years | May 29, 2026 | | Pablo Voorvaart | Senior Solutions Architect | Multi-year | May 2026 |
Stańczak, the former Nethermind CEO who joined the EF in 2025 as co-executive director, stepped down after 11 months. He stated: "While my ability to execute independently at the EF diminishes over time, my time at the organization in 2026 would feel more and more like just staying around to pass the baton." Vitalik Buterin acknowledged Stańczak "brought fresh new energy to the organization" and made it "more responsive to the outside world," according to Sherwood News.
The Foundation's board appointed Bastian Aue as interim co-executive director. New Protocol Cluster co-leads include Will Corcoran (zkVM/post-quantum), Kev Wedderburn (zkEVM), and Fredrik (Protocol Security), per DeFi Prime.
Van Epps was notably vocal on departure, publicly criticizing EF leadership's "association with the Milady NFT collection as baffling and sad." He remains with Protocol Guild, the independent funding mechanism he helped establish.
Julian Ma cited role misalignment, stating his responsibilities shifted from research toward product development. Carl Beekhuizen cited personal reasons, including time with his newborn.
Nineteen additional layoffs preceded the voluntary departures, according to reporting by Memeburn.
On March 13, 2026, the EF published a 38-page constitutional document establishing its CROPS framework: Censorship Resistant, Open Source, Private, and Secure. The mandate represents a philosophical pivot: the Foundation explicitly rejects the role of Ethereum's "owner" or central authority.
EF President Aya Miyaguchi framed the contraction as intentional. "First, debates that were meant to be technical had started to become political and personal," she stated, according to Bitcoinist. "Trying to satisfy all of them would leave us achieving nothing at all."
On staffing, Miyaguchi was direct: "As EF becomes more focused and more opinionated, the team naturally becomes smaller and more concentrated. That is part of the choice."
Buterin's May 24 post described the EF as "still being in transition" and emphasized it should be "leaner and more focused, with less emphasis on being the center of Ethereum."
Unconfirmed reporting from Cryptopolitan suggested staff faced a "sign-or-leave" ultimatum tied to the mandate. No departing contributor publicly cited the mandate as their reason for leaving. No EF confirmation of the claim was provided.
The EF reported a treasury balance of $970.2 million as of October 31, 2024, comprising $788.7 million in cryptocurrency assets and $181.5 million in non-crypto holdings. The Foundation holds less than 0.2% of all ETH in circulation.
The new treasury policy, announced in June 2025 and reaffirmed in 2026, establishes:
At 15% of $970 million, the implied annual budget is approximately $145 million, though actual 2025 spending was reported near $100 million. The Foundation receives no staking revenue and no protocol-level fee income, a structural limitation that critics have highlighted.
The EF converted approximately $100 million in ETH to stablecoins over nine months leading into early 2026, described by analysts at DeFi Prime as routine treasury operations rather than distressed selling. Against a $270 million portfolio and $100 million in annual expenses, the conversion pace appears consistent with operational requirements.
The Glamsterdam hard fork remains the nearest protocol milestone, currently targeting Q3 2026. Its scope includes:
DeFi Prime's analysis notes that FOCIL (a censorship-resistance mechanism Julian Ma worked on) and native account abstraction have been deferred to the subsequent Hegota upgrade, planned for H2 2026.
The Fusaka upgrade shipped in December 2025 without disruption, demonstrating that independent client teams can execute upgrades even during EF turbulence. The coordination mechanism, however, is qualitatively different at the Glamsterdam scale: ePBS represents a structural change to block production, not an incremental parameter adjustment.
Tim Beiko's departure carries the most institutional risk. His All Core Devs coordination role — scheduling calls, managing EIP discussions, and maintaining consensus among rival client teams — represents what multiple analysts describe as the hardest function to replace within the EF's operational model. The role is informal but load-bearing.
DeFi Prime assessed timeline slip on ePBS as "more likely than fork failure," suggesting Q4 2026 or early 2027 as a realistic window if the reshuffle impacts development velocity.
On May 22, 2026, former EF researcher Dankrad Feist published a proposal for an entirely new organization, separate from the Foundation, with explicit economic alignment to ETH. His four requirements, per Unchained Crypto:
The proposal is a direct response to the EF's price-agnostic posture. The Foundation's mandate does not reference ETH price or market competitiveness as organizational objectives. Feist's contention is that this creates a structural misalignment between the Foundation and ETH holders.
Community response polarized immediately. Ryan Adams, co-founder of Bankless, endorsed the concept. Michael Egorov, founder of Curve Finance, questioned the organization's specific objectives. Consensus researcher Potuz warned it could transform Ethereum into a "corporate chain."
No funding commitments or organizational formation have been announced. The proposal remains at the discussion stage.
ETH traded at approximately $1,670 on June 4, 2026, per CoinMarketCap, down roughly 57% from its 2025 peak near $5,000. The token declined 5.65% in the 24 hours to June 4, underperforming Bitcoin (-1.16%) and XRP (-2.83%) over the same period.
On-chain data provides a counterpoint to the governance narrative. Wallets holding at least 100,000 ETH controlled 17.41 million tokens — approximately 22.03% of total supply — the highest concentration in 10 weeks, according to CoinMarketCap data. The accumulation trend has been steady since mid-April 2026.
The causal link between Foundation departures and ETH price remains indirect. Developer sentiment feeds protocol credibility, which informs institutional confidence, which shapes capital allocation. The mechanism is real but difficult to isolate from broader macro factors: the $270 billion crypto selloff in early June affected all major assets.
Standard Chartered has maintained a $4,000 ETH target, citing staking yields and institutional adoption. Polymarket prediction contracts for ETH price before 2027 show a distribution of outcomes, though specific probabilities were not available at time of writing.
The Ethereum Foundation's 2026 reshuffle represents its most significant organizational stress test since the 2016 DAO crisis and subsequent hard fork. The difference is that the current event is intentional: the Foundation is choosing to shrink, not being forced to by external attack.
The bet is that Ethereum's development is now sufficiently decentralized across independent client teams, Protocol Guild, and application-layer builders that the Foundation can step back without breaking the coordination mechanisms that keep the network upgrading. Fusaka's clean December 2025 deployment provides one data point in favor of that thesis.
The counter-argument is that the EF's role was never about writing code — it was about setting the table for others to coordinate. Beiko's All Core Devs calls, Monnot's mechanism design work, and Van Epps' Protocol Guild stewardship were coordination infrastructure, not software deliverables. Coordination infrastructure is harder to decentralize than code.
Glamsterdam's Q3 2026 target is the first concrete test. If ePBS ships on time, the "Lean Ethereum" thesis gains empirical support. If the fork slips, the cost of the Foundation's contraction becomes measurable. The data should arrive by Q4 2026.
