Hoskinson says Vitalik’s AI warning could delay the internet’s quantum defenses

Cardano founder Charles Hoskinson accused Vitalik Buterin of undermining quantum-resistant cryptography with speculative warnings about AI-driven mathematical breakthroughs.In an Oct. 9 post, Hoskinson challenged the Ethereum co-founder's skepticism toward lattice-based cryptography, arguing that decades of security research had already accounted for the technology's known weaknesses.He warned that encouraging developers to abandon established approaches could slow the adoption of protections already being deployed across internet infrastructure, leaving systems exposed to future quantum attacks.The criticism follows Buterin's warning that AI-assisted mathematical discoveries could weaken cryptography designed to resist quantum computers.Buterin said Ethereum's long-term “lean” roadmap has moved toward hash-based signatures and proofs, avoiding lattice-based designs.Hoskinson rejected that reasoning, accusing Buterin of being too invested in Ethereum's existing research direction to reconsider its approach.“The case against lattices is the GNFS story, a.k.a. a hunch about ‘structure,' and a multiplier pulled out of thin air,” Hoskinson wrote.The dispute concerns post-quantum altern...
