Cryptographer Matthew Green Warns AI Could Weaken Crypto Math Behind Bitcoin and Ethereum Wallets

  • —OpenAI said on October 6 its unreleased AI model produced 722 mathematical manuscripts
  • —Green: AI could cut security from 128 bits to 96–108 bits, making attacks a million times cheaper
  • —Bitcoin wallets with exposed public keys and Ethereum accounts that have signed transactions are most at risk
  • —Blockstream CEO Adam Back called the warning dubious, pointing to hash-based SHRINCS signatures
Why it matters: If AI finds flaws in elliptic-curve cryptography, private keys and wallet funds could be at risk, forcing urgent protocol upgrades across the industry.
