Ethereum Foundation Loses Co-Executive Director Wang

Hsiao-Wei Wang has stepped down as co-executive director and board member of the Ethereum Foundation, effective immediately. Her departure follows a recent sabbatical and comes amid broader leadership changes and an active technical roadmap across the Ethereum ecosystem.

Why Wang left: sabbatical, reflection and a shift in priorities

Wang announced her resignation on X after returning from a planned break. She said the sabbatical gave her space to reassess priorities and the next chapter of her life, and that stepping back from a formal leadership role felt like the right decision. In her statement she thanked colleagues who supported the foundation during her absence and emphasized that she will remain an engaged member of the Ethereum community, even as she plans to spend more time closer to home.

Wang did not reveal a new role or project in her message. Instead, she framed the change as a personal pivot rather than a move away from Ethereum altogether.

Reaction from the community and Vitalik Buterin

Ethereum co-founder Vitalik Buterin acknowledged Wang’s decade-long contributions in research coordination and community building. He praised her work organizing research and consensus efforts and highlighted her role in growing the Taipei ecosystem through events and people connections. Buterin said he looks forward to seeing what Wang does next and underlined the impact she had across technical and community domains. Buterin’s comments place Wang’s departure in context: she has been active both in protocol research and in cultivating grassroots community efforts.

Leadership shake-up: how Wang’s exit fits a broader pattern

Wang’s resignation follows other leadership shifts at the Ethereum Foundation earlier in 2026. In February, Tomasz Stańczak stepped down as co-executive director; the board named Bastian Aue interim co-executive director. Aue was described at the time as someone with deep institutional knowledge who had worked closely with prior leadership on grants, operations, and enterprise partnerships.

Wang and Stańczak had been appointed co-executive directors in March 2025 in a dual-leadership arrangement while Aya Miyaguchi transitioned into a president role. The co-director model aimed to balance protocol research experience with operational stewardship; Wang’s seven years of research work — including involvement around the Beacon Chain and research governance — were cited when she joined the leadership team.

Staff transitions in the Protocol Cluster

The Foundation’s Protocol Cluster also saw changes: staff moves, sabbaticals, and role shifts affected contributors such as Barnabé Monnot, Tim Beiko, and Alex Stokes, while new leads stepped into critical areas. The reshuffle has not halted development: core teams continued work on client development, security, scaling, and coordination among client maintainers.

Funding and ongoing protocol work

Despite the personnel turnover, the Ethereum Foundation continues to fund core protocol and client work. In Q1 2026 grants, the foundation backed major client teams and infrastructure projects — including Geth, Erigon, and Lighthouse — as well as validator security tooling, zero-knowledge research, and public infrastructure efforts. These grants support client robustness, node operator tooling, and the broader developer stack essential for Ethereum’s scaling and security roadmap.

The foundation’s funding commitments underline its continuing role in enabling research and implementation across consensus, execution, and tooling, even as its leadership evolves.

Roadmap focus: Glamsterdam and technical priorities

Wang’s departure comes as Ethereum developers prepare for significant protocol upgrades. The Glamsterdam upgrade is a major focus for 2026, centering on Enshrined Proposer-Builder Separation (PBS) and Block-Level Access Lists. Those features aim to enhance block-builder transparency and improve client processing efficiency.

Other active priorities include gas repricing proposals, Layer 1 scaling work, privacy enhancements, and long-term security improvements. Client teams and researchers are collaborating on these initiatives while maintaining client diversity and validator security.

What this means for node operators and validators

For validators, node operators, and infrastructure providers, the technical roadmap and ongoing foundation grants are the key signals to watch. Continued funding for client development and validator tools aims to reduce centralization risk and improve resilience as protocol changes like PBS and access lists are implemented.

What’s next for the Ethereum Foundation and Wang

The foundation is left navigating a period of organizational transition while sustaining technical progress. Observers and community members expect the Foundation to remain one of several important actors in the ecosystem rather than a central authority — a view echoed by several leading voices within Ethereum.

Wang has not disclosed her next professional step, but the community response and her continued engagement suggest she will remain influential in research, event organization, or community initiatives. For now, the Ethereum ecosystem will watch how interim leadership and the board shepherd ongoing grants, client work, and roadmap milestones through the remainder of 2026.

Keywords naturally woven into this report include Ethereum Foundation, protocol research, Glamsterdam, Proposer-Builder Separation, Geth, Erigon, Lighthouse, zero-knowledge, validator security, Layer 1 scaling, and community governance. These themes will shape the conversation as the network advances its technical upgrades and funding priorities in the months ahead.
