Post-Quantum Cryptography

QSN uses a hybrid scheme with traditional and post-quantum cryptography for maximum security

NIST Standard

Dilithium3

NIST digital signature standard based on lattice structures. Security level 3.

5000 gas
Fast

Falcon-512

Fast post-quantum signatures with compact size. Based on NTRU lattices.

3000 gas
Max Security

SPHINCS+

Maximum security without trusted setup. Based only on hash functions.

50000 gas
Encryption

Kyber1024

NIST post-quantum encryption standard. Key Encapsulation Mechanism (KEM).

2000-3000 gas

Hybrid Scheme Ed25519 + Post-Quantum

All transactions are signed with both traditional (Ed25519) and post-quantum algorithms. This provides protection against both classical and quantum attacks simultaneously.
