Bitcoin Core Passes Third-Party Security Audit with High Marks

According to PANews, Bitcoin Core has successfully completed its first third-party security audit, confirming the software's maturity and security in safeguarding the Bitcoin network. The audit was conducted by French security firm Quarkslab, commissioned by the Open Source Technology Improvement Fund (OSTIF) and implemented on behalf of Bitcoin Core development funding organization Brink. The audit spanned 104 days from May to September, focusing on the project's most sensitive components, particularly the P2P layer and block validation logic. Despite the extensive codebase, which includes over 200,000 lines of C++ code and more than 1,200 deployed test cases, auditors found Bitcoin Core to be "highly mature and thoroughly tested." No high or medium severity vulnerabilities were discovered, only two low severity issues and several improvement suggestions related mainly to fuzz testing tools and test coverage. These findings did not affect the consensus mechanism, denial-of-service resistance, or transaction validation.
