ZEC drops 30% after Anthropic AI finds Zcash counterfeit vulnerability (www.tradingview.com)

The price of Zcash (ZEC) plummeted over 30% after a critical counterfeiting vulnerability was disclosed in the Orchard pool, potentially allowing malicious actors to mint unlimited ZEC. Taylor Hornby, a security engineer with Shielded Labs, identified the bug in May 2022 and alerted the Zcash Open Development Lab. An emergency hard fork was deployed on June 3 to address the issue, but concerns remain about whether the vulnerability had been exploited before the patch, leading to a market capitalization loss of over $3 billion. Significantly, this situation underscores the ongoing challenges faced by privacy protocols, as noted by industry experts who pointed out that similar vulnerabilities can exist in many zero-knowledge privacy protocols. Hornby utilized the AI tool Claude Opus 4.8 during his review, demonstrating how advanced technologies can aid in discovering such critical flaws. The incident raises crucial questions about the transparency and integrity of cryptocurrency supply, prompting ongoing collaboration between Shielded Labs and Zcash developers to enhance verification measures and prevent future exploits.
