Bitcoin Core has completed its first public security audit with positive results.

Quarkslab has completed an important independent security assessment of Bitcoin Core, sponsored by Brink and coordinated by OSTIF. This is the first time the project has publicly announced a third-party security audit, marking an important transparency milestone for the ecosystem. The assessment focused on core components such as the P2P network layer, how transactions are handled in the mempool, chain management logic, and key factors of the consensus mechanism.

During the audit process, the team of experts looks for structural weaknesses, logical errors, or attack surfaces that may affect the network's reliability and user safety. The results are very positive: no serious or medium-level vulnerabilities were found. The audit team only noted two low-risk issues and 13 improvement recommendations aimed at enhancing the sustainability and maintainability of the source code.
