Protocol

Bitcoin Core, hardened for the quantum era.

Bitcoin Quantum keeps Bitcoin's UTXO model, scripting system, halving schedule and SHA-256 proof-of-work intact — and replaces the signature algorithm with NIST-standardized post-quantum primitives.

Under the hood

Cryptography that outlasts the quantum threat.

Every address is generated and spent with NIST-standardized post-quantum primitives — verifiable today, secure against the computers of tomorrow.

  • CRYSTALS-Dilithium (ML-DSA, NIST FIPS 204) signatures replace ECDSA
  • BIP-360 P2MR receive addresses — the public key stays hidden until the output is spent
  • Cryptographic agility — ready to adopt new NIST PQC standards
