AI is accelerating the rewrite of Bitcoin open-source security offense and defense. Bitcoin Red Team revealed that with the help of AI, they scanned 390 projects in less than 30 hours, submitting 4,962 security findings, including 85 critical vulnerabilities and 635 high-risk vulnerabilities. During the Coldcard incident investigation and Bitcoin code audit, some teams shifted to Chinese open-source models like Kimi K3 and GLM 5.2. Multiple crypto institutions are calling for AI labs to grant certified open-source security teams long-term trusted access.
