Decentralized systems distribute control across a network rather than relying on centralized authorities. Quantum-resistant architectures use cryptographic methods that remain secure even against quantum computer attacks.

Key Concepts:

• • P2P Network Architecture
• • Quantum-Resistant Cryptography (Lattice-based algorithms)
• • Consensus Mechanisms (Proof of Stake, Proof of Work)
• • Smart Contracts and Distributed Ledgers

// Quantum-resistant key exchange algorithm
const latticeKeyExchange = async (keySize: number): Promise => {
  const crypto = new LatticeCrypto();
  const publicKey = await crypto.generatePublicKey(keySize);
  const sessionKey = await crypto.deriveSessionKey(publicKey);
  return sessionKey;
};

To create a quantum-safe decentralized system, first understand network topologies like blockchain, DAGs, and consensus algorithms. This section covers the design of secure, distributed networks.

Implement a basic decentralized application using quantum-resistant libraries and frameworks. We'll demonstrate secure communication and data integrity techniques.

import { LatticeCrypto } from 'quantum-crypto-sdk';

interface Node {
  id: string;
  publicKey: string;
  balance: number;
}

class QuantumNetwork {
  private nodes: Node[] = [];
  
  constructor() {
    // Initialize quantum-resistant security
  }

  addNode(id: string): void {
    // Add node with quantum authentication
  }
}
