Quantus Network is a Proof-of-Work Layer-1 blockchain. It protects assets from quantum computers. It builds post-quantum cryptography into the protocol. The stack uses Parity Substrate. It deploys NIST-approved signatures and encryption. Dilithium (ML-DSA) handles transactions. ML-KEM secures P2P links. Legacy elliptic curves fail against Shor. Quantus switches to lattice-based primitives. Zero-knowledge aggregation with Plonky2 and Poseidon2 keeps throughput high despite big signatures. The network handles value transfer. It manages accounts. It supports apps. Security and self-custody come first.
