Ethereum Co-Founder Warns AI May Undermine Lattice Cryptography in Two Years

Vitalik Buterin, Ethereum's co-founder, warned that rapid AI advances in mathematics could compromise lattice-based cryptography—the foundation of next-generation post-quantum security standards—within the next two years. Speaking on October 7, 2026, Buterin highlighted that artificial intelligence could accelerate mathematical breakthroughs equivalent to 50 years of traditional progress, potentially weakening cryptographic schemes that were supposed to protect digital assets against both current and future threats.
