What is Quantum Shield?

Quantum Shield protects smart contract assets against quantum computing threats using NIST FIPS 204 (ML-DSA/Dilithium) and FIPS 205 (SLH-DSA/SPHINCS+) dual post-quantum signatures, combined with a decentralized Prover Pool, VRF-based selection, and time-locked custody.

Key Features

Dual PQC Signatures — ML-DSA-65 + SLH-DSA for defense-in-depth
Prover Pool — Decentralized verification with stake-weighted selection via VRF
Time-Locked Custody — 24h normal unlock, 7-day emergency path with bond
Observer Network — Independent challenge system with quadratic slashing
On-Chain Governance — veQS token voting, security council, insurance fund
11 Sub-Applications — Consumer, Prover, Observer, Explorer, Enterprise, Governance, Admin
