Q-Chain (Quantum)

Overview

The Quantum Chain is the post-quantum security layer of Lux Network. It implements NIST-approved lattice-based cryptographic algorithms — ML-DSA for digital signatures, ML-KEM for key encapsulation, and SLH-DSA for stateless hash-based signatures.

The Quasar hybrid consensus combines classical BLS signatures with Corona post-quantum signatures, providing security against both classical and quantum computing attacks. The DAG-based processing model enables parallel transaction execution for maximum throughput.

Q-Chain serves as the security anchor for the entire network. Other chains can reference Q-Chain attestations to provide post-quantum security guarantees for their own operations.

Quick Start

Install the Lux SDK and start interacting with Quantum Chain.

import { QuantumClient } from 'luxnet/quantum'

const pq = new QuantumClient('https://quantum.lux.network')

// Generate post-quantum keypair
const keypair = await pq.generateKeypair('ml-dsa-65')

// Sign with PQ signature
const sig = await pq.sign(keypair.secretKey, message)
const valid = await pq.verify(keypair.publicKey, message, sig)
