Charles Hoskinson Accuses Vitalik Buterin of Overstating AI Threat to Lattice Cryptography

Charles Hoskinson challenges Vitalik Buterin’s AI warning on lattice cryptography, questioning whether the threat justifies major changes to post-quantum security. Cardano founder Charles Hoskinson has launched a detailed technical rebuttal against Ethereum co-founder Vitalik Buterin’s warning that artificial intelligence could weaken lattice-based cryptography within two years. Hoskinson argued that Buterin’s proposed shift toward hash-based cryptography rests on speculative attack scenarios and an unjustified recommendation to increase lattice security parameters tenfold. Hoskinson disputed Buterin’s comparison between potential AI-driven attacks on lattice cryptography and the mathematical breakthrough that produced the General Number Field Sieve, an algorithm used to factor large integers.
