  • Eli Ben-Sasson, a cryptographer, helped create the Zcash cryptocurrency but was surprised by how machine intelligence later exposed a long-ignored security flaw.
  • A security researcher utilized Anthropic’s Claude Opus 4.8 AI to discover a critical vulnerability in Zcash that had evaded detection by human experts for over four years.
  • After the flaw was disclosed in early June, Zcash’s token price plummeted about 50%, as investors reevaluated the security of its privacy network.
  • Zcash’s value proposition hinges heavily on its advanced cryptography for transaction privacy, and the detected flaw threatened this core strength.
  • The incident raised concerns about how artificial intelligence might influence and potentially outperform human oversight in identifying vulnerabilities in crypto networks.
