Traditional Bitcoin addresses rely on elliptic curve cryptography, vulnerable to quantum attacks like Shor’s algorithm. To mitigate this, we use quantum-safe algorithms such as hash-based cryptography.


Steps to Create a Quantum-Resistant Address

1- Install Dependencies

Use Python's hashlib for hashing. Install additional libraries with:

pip install pqcrypto

2- Generate Quantum-Resistant Private/Public Key

Use Python to generate two sets of random private keys and their public key hashes:

import os, hashlib

def generate_private_key():
    priv_key_0 = [os.urandom(32) for _ in range(256)]
    priv_key_1 = [os.urandom(32) for _ in range(256)]
    return priv_key_0, priv_key_1

def generate_public_key(priv_key_0, priv_key_1):
    pub_key_0 = [hashlib.sha256(x).digest() for x in priv_key_0]
    pub_key_1 = [hashlib.sha256(x).digest() for x in priv_key_1]
    return pub_key_0, pub_key_1

3- Create Hash-Based Bitcoin-Like Address

Hash the public key with SHA-256 and RIPEMD-160 to generate an address:

def public_key_to_address(pub_key_0, pub_key_1):
    concatenated_pub_key = b''.join(pub_key_0 + pub_key_1)
    sha256_pub_key = hashlib.sha256(concatenated_pub_key).digest()
    ripemd160 = hashlib.new('ripemd160')
    ripemd160.update(sha256_pub_key)
    return ripemd160.hexdigest()

4 - Signing Transactions

Use the private key to reveal specific parts of the key to sign transactions securely.
