According to Cointelegraph, Bitcoin Core has passed its first third-party security audit, confirming that the software securing the Bitcoin network is highly mature, with no serious vulnerabilities found.The audit was conducted by the French security company Quarkslab, commissioned by the Open Source Technology Improvement Fund (OSTIF) and implemented on behalf of the Bitcoin Core development funding organization Brink. During the 104-day audit period from May to September, the reviewers assessed the most sensitive components of the project, with particular attention to the P2P layer and block validation logic. The report noted that despite the large size of the Bitcoin Core codebase, which contains over 200,000 lines of C++ code and more than 1,200 deployed test cases, the auditors assessed it as "the most mature and well-tested." The team found no high or medium severity vulnerabilities, only two low severity issues, along with a series of recommendations for improvements mainly related to fuzz testing tools and test coverage. These findings did not impact the consensus mechanism, denial-of-service resistance, or transaction validation.
