Hsiao Wei Wang, co-executive director and board member of the Ethereum Foundation (EF), has announced her departure from the foundation, shortly after co-executive director Tomasz Stańczak left in February this year.

 

“After my sabbatical, I have decided to step down as co-executive director and board member of the Ethereum Foundation, effective today,” Wang wrote in an X post.

 

“Serving as EF co-executive director let me see the bigger picture of how the Ethereum community collaborates. I’m proud of what we’ve accomplished, not only at the EF, but across the builders, researchers, educators, validators, users, and many other contributors who have helped build, maintain, secure, and use the infrastructure and applications on top of it.”

 

Wang joined the EF research team in 2017, where she worked on protocol design, consensus mechanisms, sharding proofs-of-concept, and distributed systems. In March 2025, she was appointed co-executive director and board member alongside Tomasz Stańczak. During her time at the EF, Wang contributed to a range of projects, including sharding research, data availability sampling, EIP 4844, ETHTaipei, and the Taipei Seminar.

 

Reacting to her departure, Ethereum co-founder Vitalik Buterin commended Wang for her contributions to the foundation. “I still remember her early days in the Ethereum research community, first outside the Foundation and then inside it, and the thought and care she put into making Ethereum research and consensus work more organized and legible,” Buterin wrote in an X post.

 

“Last year, she, along with Stańczak, voluntarily took on the burden of what is perhaps the most challenging position in the Ethereum Foundation, at one of the most challenging times for Ethereum and, realistically, a challenging time for all of humanity. She handled the task skillfully and gracefully, and has constantly strived to find and insist on outcomes that are right both for the Ethereum protocol and for the human beings who build and maintain it.”

 

Wang’s departure from the Ethereum Foundation comes as several notable researchers have left the organization, including Tomasz Stańczak and Josh Stark, who departed in April. So far, at least eight senior researchers have left the Ethereum Foundation this year.
