Agentic coding produced a 700,000-line Ethereum client prototype aligned with the 2030 roadmap in weeks. Buterin urges pairing faster AI coding with formal verification, expanded test suites, and multi-client checks. He also detailed a quantum-resistance roadmap replacing BLS and adding

In brief Buterin pointed out four Ethereum components that rely on cryptography vulnerable to quantum attacks. The plan replaces BLS, KZG, and ECDSA with hash-based, lattice-based, or STARK-based systems. Recursive aggregation aims to reduce high gas costs from quantum-safe signatures and
