Vitalik Buterin Warns AI Threatens Lattice Cryptography as Ethereum Weighs Hash-Only Shift

Ethereum is pivoting its development roadmap toward a hash-only architecture for signatures and proofs to guard against artificial intelligence risks, co-founder Vitalik Buterin warned. The debate erupted after Ethereum Foundation researcher Justin Drake urged an industry transition to 'bunker mode'—moving funds to fresh addresses with unexposed public keys—warning AI could crack ECDSA in months. Buterin, Coinbase's Yehuda Lindell, and Jameson Lopp cautioned against rushed migrations, citing operational error risks. Spot Bitcoin and Ethereum ETFs registered single-day net outflows of $485 million and $161 million, respectively, with Ether dropping to $2,540.
