ZKPoSP: Post-Quantum Zero-Knowledge Proofs for Hierarchical Deterministic Wallets

본문 미리보기

Recent advances in quantum hardware, including Google's Willow processor, have substantially narrowed the timeline to cryptographically relevant quantum computers. In the blockchain setting, where addresses and key derivation standards such as BIP32, BIP44, and SLIP-10 are the dominant infrastructure for wallet management, a quantum computer running Shor's algorithm can recover any elliptic-curve private key from the corresponding public key, threatening every wallet in production today.
