The Central Question

Can Ethereum survive the quantum transition with formally verified cryptographic primitives? This project formalizes the post-quantum migration path: replacing ECDSA with XMSS hash-based signatures, replacing KZG polynomial commitments with Sumcheck polynomial IOPs under the Fiat-Shamir transform, and constructing PQ HTLCs for quantum-safe atomic swaps. Based on Drake and Khovratovich’s Ethereum Foundation research.
