ZKPoSP: Quantum-Resistant Wallet Security Solution Introduced

Researchers have introduced ZKPoSP (Zero-Knowledge Proof of Seed Provenance), a new approach to securing blockchain wallets against quantum threats. With the development of quantum computers, experts warn that classical signing steps in current wallet infrastructure are vulnerable to attacks.

ZKPoSP addresses this issue by replacing the classical signing step with an NIZK (Non-Interactive Zero-Knowledge) proof that certifies knowledge of the root seed and derivation chain. This approach maintains post-quantum security, relying on the difficulty of hash functions and the robustness of NIZK against quantum adversaries.

The researchers also introduced QBIP32, a novel key derivation strategy based on a keyed function HASH768 (instantiated using KMAC256). This approach generates signing scalars, explicit quantum-safe witnesses, and chain codes within a single call, applicable across various elliptic curve groups.
