Bitcoin.com News reported on February 6th that Bitcoin Core developer Gloria Zhao has resigned from her maintainer position and revoked her cryptographic signing key. She has long focused on mempool validation, transaction relaying, and fee estimation, and her resignation does not affect Bitcoin's consensus rules, network security, or transaction processing. The report pointed out that resigning maintainers and revoking keys are common practices in open-source projects. Bitcoin Core maintainers are a trusted small group of developers responsible for code review, approval of updates, and digitally signing official releases with their keys. Zhao has contributed over six years to Bitcoin Core development, but her work did not involve changing Bitcoin's underlying protocol rules. She did not comment on the specific reasons for her departure.
