David Schwartz, one of the architects of the XRP Ledger and Ripple’s CTO emeritus, says his retirement from active development, which began in November, coincided with a major shift in cybersecurity. In a test on the Linux kernel, OpenAI’s model identified 2,308 potential flaws, confirmed hundreds of privilege-escalation vulnerabilities and produced 291 working proofs of concept for memory leaks. The researchers also documented at least ten previously unknown classes of hacking methods, while API credits cost $1.2 million. The autonomous discovery of zero-day vulnerabilities within hours could reduce the relevance of manual auditing of open-source code, which underpins blockchain security. Schwartz nevertheless continues to monitor the XRP Ledger, including a node handling about 110,000 incoming messages per second with more than 550 active peers.
