Vitalik Buterin Warns AI Could Undermine Cryptography Within Two Years

Ethereum co-founder Vitalik Buterin warned that AI could accelerate mathematical advances enough to weaken lattice-based cryptography, including ML-DSA and FHE, within two years, potentially putting ECDSA at risk sooner than expected. He said Ethereum’s Lean roadmap is shifting toward hash-based signatures to reduce these risks. Buterin advised users to favor addresses that have never sent transactions and use off-chain multisig signing where practical, while cautioning against rushed asset migrations. — link
