According to CoinMeta, long-time Bitcoin figure CobraBitcoin warns that with the release of more powerful models by OpenAI and Anthropic, the digital currency industry is facing new security challenges. He points out that most of Bitcoin's critical infrastructure is open-source, making it easy for machines to analyze. CobraBitcoin is concerned about the next major vulnerabilities, especially after OpenAI released GPT-6 and Astra and Anthropic launched Claude Fable 5.1; these models are capable of performing more complex software engineering tasks. Astra achieved a 100% perfect score in the exploitbench benchmark tests, demonstrating its ability to identify security flaws and develop attack techniques.
