Bitcoin Core passes first third-party security audit with no critical vulnerabilities found

ChainCatcher news, according to Cointelegraph, Bitcoin Core has passed its first third-party security audit. The audit results confirm that this software, which safeguards the Bitcoin network, is highly mature and no critical vulnerabilities were found.

This 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, reviewers evaluated the most sensitive components of the project, with particular focus on the P2P layer and block validation logic. The report pointed out that although the Bitcoin Core codebase is large, containing over 200,000 lines of C++ code and more than 1,200 deployed test cases, auditors assessed it as "highly mature and thoroughly tested." The team did not find any high or medium severity vulnerabilities, only two low severity issues, as well as a series of improvement suggestions mainly related to fuzz testing tools and test coverage. None of these findings affected the consensus mechanism, denial-of-service resistance, or transaction validation.
