Introducing Bitcoin Quantum
Bitcoin evolved for the quantum era
What is Bitcoin Quantum?
Bitcoin Quantum is Bitcoin designed for the post-quantum era. It maintains Bitcoin's economic model and network architecture while implementing quantum-resistant cryptographic primitives and enhanced transaction capacity specifically designed for large post-quantum signatures.
Like Bitcoin, Bitcoin Quantum is peer-to-peer with no central authority or banks. Managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin Quantum is open, its design is public, nobody owns or controls Bitcoin Quantum and everyone can take part.
The Quantum Threat
Quantum computers use the principles of quantum mechanics to process information in ways that classical computers cannot. While this technology holds immense promise for scientific advancement, it also poses a significant threat to current cryptographic systems.
- Current Bitcoin uses ECDSA (Elliptic Curve Digital Signature Algorithm)
- Quantum computers could break ECDSA using Shor's algorithm
- This could compromise user's private keys, making funds vulnerable to theft or unauthorized access
- The threat is real and approaching quickly
Post-Quantum Architecture
Bitcoin's security model, rebuilt for the quantum era.
Bitcoin Quantum combines NIST-standardized post-quantum cryptography with Bitcoin's proven architecture to create a digital store of value secure against both classical and quantum threats.
- Quantum-Resistant Signatures: NIST-standardized CRYSTALS-Dilithium signatures replace Bitcoin's quantum-vulnerable ECDSA, providing long-term security against emerging quantum computers.
- Bitcoin Foundation: Built on Bitcoin's proven UTXO model, scripting system, and SHA-256 consensus—battle-tested architecture with modern cryptographic foundations.
- Cryptographic Agility: Extensible protocol design enables future integration of additional post-quantum algorithms as cryptographic standards evolve.
