Vitalik Buterin urges calm as AI raises new fears over Bitcoin and Ethereum cryptography security
Summary
Vitalik Buterin warned that AI-driven mathematical advances could eventually weaken elliptic-curve cryptography and lattice-based post-quantum systems, though there is no evidence that blockchain signatures have been practically broken. He urged users not to rush into wallet migrations, saying mistakes may pose a more immediate risk. Ethereum developers are increasingly favoring hash-based cryptography, while Buterin suggested larger security parameters may be needed for systems that depend on mathematical structures. Users can reduce exposure by keeping funds in addresses that have never signed transactions; multisig operators can rotate signer keys. The warning also applies to secure messaging, VPNs and other encrypted services.
