Ethereum Researchers Warn AI Math Advances Could Break ECDSA, Urge ‘Bunker Mode’

This is a rare case of Ethereum's own researchers flagging an AI-driven threat to ECDSA that could arrive before quantum computing does, which reframes the usual 'wait for Q-day' posture. It affects every holder whose coins sit in addresses that have already signed, since exposed public keys become the weak point. Buterin's caution against rushed migration, and his warning that lattice-based and FHE schemes may not be AI-proof either, suggests the industry's post-quantum assumptions deserve scrutiny. Watch whether fresh-address hygiene becomes standard practice, and whether the proposed alternatives hold up.
