Bitcoin Core developer Niklas Gögge warned that AI-driven vulnerability scanning is reshaping Bitcoin security by lowering the cost of finding flaws. Attackers may identify catastrophic vulnerabilities with only hundreds of dollars in computing costs. More than 1,000 reports have been generated for Bitcoin Core by Project Loupe, Bitcoin Red Team and individual contributors, but none has so far uncovered a high-risk or critical vulnerability. Gögge said relying on increasingly powerful models to find bugs before attackers is not sustainable, urging developers to build automated testing, fuzz testing (automated input-based bug detection) and property-based testing (checking defined system behaviors) that can prevent entire classes of vulnerabilities. Key Bitcoin Core components have undergone more than 100 years of cumulative CPU fuzz testing, alongside decades of Bitcoin node-network simulations.
