Vitalik Buterin Warns of AI-Driven Cryptography Risks, Urges Multisig Key Rotation

Ethereum co-founder Vitalik Buterin has warned that artificial intelligence poses an emerging threat to widely-used cryptographic systems, particularly ECDSA, the elliptic curve signature algorithm securing billions in blockchain assets. In a recent statement, Buterin highlighted that AI-accelerated mathematical research could weaken lattice-based cryptography within two years and poses growing risks to ECDSA and other established schemes—potentially before quantum computing reaches practical threat levels.
