Bitcoin Core developer Gloria Zhao resigns as maintainer

Bitcoin Core developer Gloria Zhao has resigned from her position as maintainer and revoked the encryption signature key. She has made significant contributions in the fields of memory pool verification, transaction forwarding, and cost estimation, but her work has not involved changes to the underlying protocol rules of Bitcoin. Resignation and revocation of keys by maintainers is a common practice in open source projects. Bitcoin Core Maintainers is a small trusted developer group responsible for code review, update approval, and digital signatures for official versions. Zhao has contributed to the development of Bitcoin core for over six years, and has not responded to the specific reasons for her resignation.
