Ethereum’s Brain Drain: Nine Senior Researchers Depart the Foundation in 2026
Nine prominent researchers have left the Ethereum Foundation in 2026. We examine what the departures mean for Ethereum’s development roadmap and future.
Nine senior researchers and protocol engineers have departed the Ethereum Foundation in the first five months of 2026, prompting discussion within the Ethereum community about the Foundation’s ability to attract and retain the talent needed to execute on its ambitious development roadmap. The departures span multiple teams within the Foundation, including researchers working on consensus layer improvements, cryptography, and developer experience.
The Ethereum Foundation is the nonprofit organisation that provides a significant portion of the funding and coordination for Ethereum’s core protocol development. While Ethereum is an open-source project with no single controlling entity, the Foundation’s research teams have historically played a central role in advancing the protocol.
Who Has Left and Why
The Foundation has not commented publicly on individual departures, and most researchers who have left have been similarly discreet. However, in public statements and interviews, several common themes have emerged.
Compensation is one factor. Foundation researchers are paid academic-style salaries that, while comfortable, are significantly below what private AI companies and well-funded blockchain startups offer for comparable talent. Several departing researchers have joined AI companies — including Anthropic, DeepMind, and several AI safety startups — where salaries are substantially higher.
Frustration with the pace of development is another theme. Ethereum’s roadmap — which includes full implementation of danksharding, statelessness, and a range of cryptographic upgrades — is technically ambitious and moving more slowly than some researchers believe the competitive landscape requires. Researchers who want to see faster iteration have found private sector environments more accommodating.
The Names and Their New Destinations
Among the notable departures, several researchers have moved to competing Layer 1 blockchain projects, where they are working on alternative approaches to the scalability problems Ethereum is tackling. Others have moved to Layer 2 infrastructure companies — Arbitrum, Optimism, and Polygon — which benefit from Ethereum’s security model but operate with private company resources and incentives.
The movement of talent from the Foundation to Layer 2 companies is particularly interesting. These researchers are not abandoning the Ethereum ecosystem — they remain committed to Ethereum as a base layer — but they are choosing to work within the commercial incentive structures of the companies building on top of it rather than within the Foundation’s nonprofit model.
What This Means for the Ethereum Roadmap
Ethereum’s core development is coordinated through a system of Ethereum Improvement Proposals (EIPs) and a series of consensus and execution client teams. The Foundation does not have a monopoly on protocol development — client teams including Prysm, Lighthouse, Geth, and Nethermind maintain their own engineering teams, many of which are funded by foundation grants but independently operated.
In this context, the Foundation’s researcher departures do not directly threaten Ethereum’s development continuity. The EIP process continues, client teams are active, and the broader developer community is large and growing. Ethereum protocol development is more resilient to individual departures than a centralised project would be.
The more significant risk is to long-term research — the work on cryptographic primitives, formal verification, and protocol theory that takes years to produce results and requires deep sustained expertise. The Foundation’s research teams have historically been responsible for this work, and rebuilding that capacity takes time.
Ethereum vs the Competition
The departures come at a moment when Ethereum faces meaningful competition from alternative Layer 1 blockchains. Solana has captured significant DeFi and NFT market share. Aptos and Sui — both founded by former Meta Diem researchers — have attracted developer activity with their Move-based virtual machines. Monad, a new high-performance EVM-compatible chain, has secured substantial venture funding.
Ethereum’s competitive advantages — its security model, decentralisation, network effects, and developer tooling ecosystem — remain substantial. But maintaining those advantages requires continuous protocol development and innovation. A weakened research function at the Foundation, even temporarily, could slow the pace of that development.
The Foundation’s Response
Ethereum Foundation Executive Director Aya Miyaguchi has acknowledged the departures but has characterised them as part of a healthy ecosystem maturation. “When researchers leave the Foundation to build on Ethereum, that is not a failure — it is success,” she said in a statement. The Foundation has indicated it is actively recruiting to fill the vacant positions.
The Foundation also has substantial financial resources. Its ETH treasury — accumulated during Ethereum’s early development — has historically been large enough to fund significant hiring. Whether it chooses to compete more aggressively on compensation or maintain its current approach remains to be seen.
What UK Ethereum Holders Should Know
For UK investors holding Ether, the researcher departures are worth monitoring but not immediately alarming. Ethereum’s network has been running without interruption, Layer 2 activity is growing strongly, and the upgrade roadmap — while slower than some would like — continues to progress.
The longer-term question is whether Ethereum’s development governance model is sustainable as the competitive landscape intensifies. That is a legitimate concern, but one that will play out over years rather than months.
