Introduction to Post-Quantum Cryptography
The rise of quantum computing poses existential threats to traditional cryptographic systems, including Bitcoin's elliptic curve cryptography. With major entities like the NSA, Google, and Microsoft adopting quantum-safe cryptography, integrating post-quantum algorithms into blockchain technology has become imperative.
Quantum-Safe Signatures
- XMSS (eXtended Merkle Signature Scheme): A hash-based, stateful signature scheme resistant to quantum attacks.
- Ensures 128-bit security against both classical and quantum computers.
Quantum-Safe Privacy
- Post-quantum zero-knowledge proofs: Enable anonymous transactions without compromising security.
Quantum-Safe Mining
- Equihash96x3: A quantum-resistant proof-of-work algorithm with unique parameters (96, 3).
Why Bitcoin Post-Quantum?
Hardfork Details
- Block height #555,000: All Bitcoin holders at this snapshot receive equivalent balances in Bitcoin Post-Quantum (BPQ).
Key features:
- Retains Bitcoin’s core functionalities.
- Enhances security via quantum-safe signatures and zero-knowledge proofs.

Coin Allocation
- Total supply: 21,000,000 BPQ (mirroring Bitcoin’s scarcity).
Distribution:
- Claimable by Bitcoin holders at fork block height.
- Mining rewards adjusted post-ECC disablement (December 2019).
FAQs
1. How do I claim my BPQ coins?
If you held Bitcoin at block #555,000, you can claim BPQ via a supported wallet (e.g., Electrum-based BPQ wallet).
2. Is BPQ mining different from Bitcoin?
Yes. BPQ uses Equihash96x3, a quantum-resistant PoW algorithm, requiring specialized mining setups.
3. What happens to unclaimed coins after ECC disablement?
Unclaimed coins (in non-quantum-safe addresses) will be burned to prevent quantum vulnerabilities.
4. How does BPQ ensure privacy?
Through post-quantum zero-knowledge proofs, ensuring transaction anonymity without compromising security.
5. Can BPQ integrate with Lightning Network?
Yes. SegWit support enables Lightning Network compatibility for instant micropayments.
