[CZ: Response to Vitalik's Discussion on AI and Cryptographic Security] CZ responded on the X platform to Vitalik's article about how AI-accelerated mathematical research might impact cryptographic security. He humorously remarked that Vitalik's math skills score 99.99 points, while his own score is 0.01 points, joking that perhaps the two of them together could achieve something. CZ stated that even if people don't fully understand Vitalik's article, it's still worth reading such an interesting analysis and discussion. Previously, Vitalik Buterin had published an article warning that AI-accelerated mathematical research could, within the next two years, weaken the security of lattice-based cryptographic systems, including technologies like ML-DSA and fully homomorphic encryption (FHE). He also noted that it might even pose a risk to breaking ECDSA. As a result, Ethereum's Lean roadmap has shifted toward a pure hash-based signature scheme.
