"The way to save Ethereum is for the community to create an organization that's economically aligned with Ethereum and accountable to it." — Dankrad Feist, Former Ethereum Foundation Researcher
Nine senior researchers have departed the Ethereum Foundation (EF) in 2026, five of them in May alone. The exits span protocol coordination leads, Beacon Chain architects, and censorship-resistance engineers. Core developer contributors have fallen from 225 in May 2025 to 169 as of May 19, 2026 — a 25% decline in twelve months.
The departures follow the EF's release of a 38-page organizational mandate in March 2026, which required staff sign-off and triggered immediate backlash over its tone, its Milady-inspired imagery, and what multiple departing contributors described as a misalignment between the Foundation's ideological priorities and Ethereum's competitive needs. ETH trades at $2,116 as of May 21, down roughly $435 year-over-year, while the Foundation's tracked treasury has fallen to approximately 92,548 ETH ($214.8 million) — enough to cover roughly two years of operations at its current $100 million annual burn rate.
The talent is not disappearing from crypto. It is migrating to commercially funded competitors. Dankrad Feist, the co-creator of Danksharding, left for Stripe-backed Layer 1 Tempo. Others have moved to Protocol Guild, independent research, or rival ecosystems altogether.
The following senior contributors have departed the Ethereum Foundation in 2026:
| Name | Role / Contribution | Tenure | Departure Date | Destination | |------|---------------------|--------|----------------|-------------| | Dankrad Feist | Co-creator of Danksharding; strategic advisor | 2018–2026 | Q1 2026 | Tempo (Stripe/Paradigm L1) | | Tim Beiko | Protocol coordinator; led hard fork coordination | Multi-year | Q1 2026 | Not disclosed | | Barnabé Monnot | Mechanism design researcher | Multi-year | Q1 2026 | Not disclosed | | Trent Van Epps | Protocol Guild organizer; community operations | 5 years | April 2026 | Protocol Guild (independent) | | Alex Stokes | Core protocol researcher | Multi-year | 2026 | Not disclosed | | Josh Stark | Operations and writing lead | Multi-year | 2026 | Not disclosed | | Tomasz Stańczak | Former co-executive director | Multi-year | 2026 | Not disclosed | | Carl Beek | Beacon Chain researcher; PoS transition architect | 7 years | May 29, 2026 | Personal leave | | Julian Ma | FOCIL (EIP-7805) author; Fast Confirmation Rule | 4 years | May 2026 | Product/growth focus |
Julian Ma's departure removes the primary author of FOCIL, a censorship-resistance mechanism that prevents proposer seat trading, and the Fast Confirmation Rule, which compressed L2-to-L1 bridging time to approximately 13 seconds. Carl Beek's exit closes a seven-year tenure that included foundational work on the Beacon Chain and Ethereum's proof-of-stake transition.
Feist's move is the most structurally significant. He joined Tempo, a payments-focused Layer 1 backed by Stripe and Paradigm. While Feist announced he would remain as a research advisor to the EF, his primary alignment shifted to a commercially funded, stablecoin-optimized chain — a direct competitor for settlement volume.
On March 13, 2026, the Ethereum Foundation published a 38-page mandate document intended to formalize its organizational role. The document outlined the EF as a neutral steward focused on maintaining Ethereum's "censorship resistant, open source, private, and secure" (CROPS) properties.
The document triggered controversy on multiple fronts:
Content and tone. The cover featured anime-style imagery with text bubbles reading "My heart glitches for you" and "divinely guided and protected." Page 34 included a Milady e-girl illustration declaring "I can't believe we all won forever." Page 11 referenced the "Source Seppuku License," a satirical software license hosted on the Remilia wiki. Remilia is the collective behind the Milady Maker NFT collection; Vitalik Buterin uses a Milady NFT as his X profile photo.
Sign-off requirement. According to multiple reports, EF staff were asked to sign the mandate document or face termination. This framing converted what could have been an internal mission statement into a loyalty test.
Resignations followed. Over half a dozen contributors announced departures in the weeks after the document's release. EthereumDaily, an account with over 100,000 followers on X, attributed the exits to the mandate "intentionally shrinking" the workforce.
The EF has not publicly explained the connection between the mandate and the departures.
The talent drain extends beyond the Foundation's core team.
Ethereum still leads all chains in absolute developer count. Electric Capital's 2026 report shows 31,869 total Ethereum ecosystem developers versus Solana's 17,708. The concern is trajectory, not current position: Ethereum's lead is narrowing while its most experienced protocol-level talent exits.
The Ethereum Foundation's financial position constrains its ability to compete for talent on compensation.
In February 2026, the EF launched a staking initiative targeting 70,000 ETH. By April, it had reached the target, generating an estimated $3.9–5.4 million annually at the 2.7%–3.8% APY range typical for institutional stakers. The Foundation subsequently unstaked 21,271 ETH (~$49.7 million) for operational rebalancing.
In May, the EF finalized a sale of 10,000 ETH to BitMine as part of its treasury diversification strategy.
Feist highlighted the structural problem: the EF controls less than 0.1% of all ETH and receives no direct flow of staking or fee revenue from the network. On-chain analysis published by CryptoTimes in April projected EF holdings could reach zero by 2027 at current spending rates absent new revenue sources.
The talent exodus occurs as Ethereum faces measurable competitive pressure.
TVL: Ethereum holds approximately $55.6 billion in DeFi TVL through April 2026, representing 68% of the global $94 billion DeFi market. Solana holds ~$8 billion.
Activity metrics: Solana processes 3.6 million daily active addresses versus Ethereum's 530,000. Solana's weekly DEX volume reached $11.49 billion in April 2026, exceeding Ethereum's $7.62 billion by 51%.
Fee revenue: Hyperliquid, an L1 not in Ethereum's ecosystem, captured 43% of all blockchain fees in May 2026, according to webthreepedia analysis. Six banks deployed on Solana in six weeks during the same period.
Price performance: ETH at $2,116 (May 21) versus approximately $2,550 a year ago represents a ~17% decline. Ethereum's market capitalization stands at roughly $233 billion.
The data suggests structural specialization is underway. Ethereum retains dominance in institutional DeFi and RWA tokenization, where its unbroken uptime record matters. Consumer applications, high-frequency trading, and stablecoin payments are migrating to faster, cheaper chains.
Feist's post-departure commentary articulated a specific thesis: the Ethereum Foundation's governance structure is fundamentally misaligned with the network's economic interests.
His argument has three components:
No revenue link. The EF holds a finite and depleting ETH treasury but receives no ongoing share of network fees, MEV, or staking revenue. Every other major L1 foundation — Solana Foundation, Avalanche Foundation — has some form of ongoing economic connection to its network's activity.
No accountability mechanism. The EF is a Swiss Stiftung (foundation) with no token-holder governance, no board elections, and no formal reporting obligations to the Ethereum community beyond voluntary transparency reports.
Proposed solution. Feist called for the community to "create an organization that's economically aligned with Ethereum and accountable to it" — implying a new entity with permanent funding, explicit accountability, and leadership focused on growth rather than ideological stewardship.
This framing resonates with a broader criticism voiced by journalist Laura Shin and others: that the EF prioritizes philosophical neutrality over competitive execution, and that this posture is costing Ethereum market share.
The Ethereum Foundation's 2026 departures represent a concentration of institutional knowledge loss at the protocol layer. The engineers who built the Beacon Chain, designed censorship-resistance mechanisms, and coordinated Ethereum's hard forks are now outside the organization. Some remain in the broader ecosystem; others have moved to direct competitors.
The Foundation's response — or lack thereof — will determine whether this is a manageable transition or the beginning of a structural governance crisis. The EF has not publicly addressed the departures, the mandate controversy, or the treasury depletion timeline. Meanwhile, the network's competitive position, while still dominant in DeFi TVL and developer count, is eroding on activity metrics, fee revenue, and price performance.
The economic alignment question raised by Feist is the central unresolved issue. A foundation that controls 0.1% of its network's token supply, burns $100 million annually, has no revenue mechanism, and has now lost nine senior researchers in five months faces a straightforward sustainability problem. The data does not indicate how — or whether — the current leadership intends to solve it.
