Bitcoin Core Audit Reveals No Major Security Flaws

A first-of-its-kind security audit has confirmed that Bitcoin Core’s software is highly mature and secure. The review, conducted by French security firm Quarkslab and commissioned by OSTIF on behalf of Brink, examined the project’s most sensitive components, including peer-to-peer networking and block validation logic, for a 104-day period between May and September. The audit found no high or medium-severity vulnerabilities, identifying only two low-severity issues and some recommendations for improving fuzzing harnesses and test coverage.
