AI Could Weaken Ethereum Security as Cryptographic Risks Grow, Vitalik Buterin Warns

Ethereum co-founder Vitalik Buterin has warned that advances in artificial intelligence could weaken cryptographic systems protecting digital assets, encrypted communications, and blockchain networks. Buterin urged developers to prepare for potential AI vulnerabilities in both conventional and quantum-resistant cryptography, while cautioning Ethereum and other cryptocurrency holders against rushing to move their funds between wallets. In a post on X on October 8, Buterin identified lattice-based cryptography as a particular area of concern, arguing that AI-assisted mathematical research could uncover weaknesses that researchers have not yet discovered.
