According to Wu Blockchain, Vitalik Buterin stated that Ethereum currently has four types of quantum vulnerabilities: consensus layer BLS signatures, KZG commitments and proofs dependent on data availability, EOA's ECDSA signatures, and application layer ZK proofs based on KZG or Groth16. The proposed mitigation strategy involves phased replacements: replacing BLS in the consensus layer with hash-based signatures (like Winternitz variants) combined with STARK aggregation, while carefully selecting new core hash functions; migrating data availability from KZG to STARK, addressing issues with 2D DAS linear properties and erasure code proofs; introducing native account abstraction (EIP-8141) for EOA to support any quantum-resistant signature algorithm, combined with vectorized precompilation and protocol-level recursive aggregation to reduce verification costs; and compressing extensive verification logic into minimal on-chain verification for application layer proofs through protocol-level recursive signatures and proof aggregation. https://www.(wublock123.com)/index.php?m=content&c=index&a=show&catid=6&id=57280
