“Bitcoin Core, the widely used software running the world’s largest blockchain, has completed its first publicly available third-party security audit. The review was conducted by cybersecurity firm Quarkslab, funded by Brink, and coordinated by the Open Source Technology Improvement Fund (OSTIF). The engagement marks a major milestone for Bitcoin’s security lifecycle, providing an independent examination of software that secures trillions of dollars in value. Bitcoin Core has evolved significantly since 2009, with more than 46,000 commits and contributions from dozens of developers. Despite its maturity, the project had never undergone a full public audit from an external firm, an absence this review aimed to address.” (11/25/25)
