Ethereum has unveiled a comprehensive roadmap to address quantum vulnerabilities in its network, focusing on four key areas: consensus-layer BLS signatures, data availability, EOA signatures, and application-layer ZK proofs. The plan involves replacing BLS signatures with hash-based signatures and using STARKs for aggregation, while carefully selecting a robust hash function. For data availability, Ethereum plans to transition from KZG commitments to STARKs, despite challenges in maintaining linearity and managing larger proof sizes. The roadmap also includes introducing native account abstraction to support quantum-resistant signature algorithms, aiming to reduce verification costs through vectorized math precompiles and recursive aggregation. In terms of proofs, Ethereum seeks to lower the gas costs of quantum-resistant STARKs by implementing protocol-layer recursive signature and proof aggregation, as outlined in EIP-8141. This approach aims to streamline validation processes and minimize on-chain data, enhancing the network's resilience against quantum threats.
