**[Bitcoin Core Completes First Third-Party Security Audit, No Critical Vulnerabilities Found]** Bitcoin Core has successfully undergone its first third-party security audit, with results showing no high-severity or medium-severity vulnerabilities. The audit was conducted by French security firm Quarkslab, commissioned by the Open Source Technology Improvement Fund (OSTIF), and implemented by Bitcoin Core development funding organization Brink. The audit lasted 104 days and focused on evaluating the most sensitive components of the project, including the P2P layer and block validation logic. Despite the large codebase, which consists of over 200,000 lines of C++ code and more than 1,200 test cases, auditors deemed the code to be "highly mature and thoroughly tested." The audit identified only two low-severity issues and provided some recommendations related to fuzz testing tools and test coverage improvements. These issues did not impact the consensus mechanism, resistance to denial-of-service attacks, or transaction validation.
