Quantum-resistant signatures
Lattice- and hash-based signature schemes replace ECDSA, so funds stay protected even against Shor's algorithm on a fault-tolerant quantum machine.
Post-quantum bitcoin
Bitcoin, secured for the quantum era.
The same 21 million coins and the same network you trust — rebuilt on cryptography that quantum computers cannot break.

NIST-standardized signatures
Our thesis
Bitcoin solved digital scarcity. Bitcoin Quantum keeps it sound for the next fifty years.
A sufficiently powerful quantum computer could one day break the elliptic-curve signatures that protect ordinary Bitcoin wallets. Bitcoin Quantum closes that door before it opens.
We preserve everything that makes Bitcoin sound money — its supply schedule, proof-of-work consensus and peer-to-peer architecture — and swap the cryptography underneath for primitives proven resistant to quantum attack.
The technology
Three changes. Everything else stays Bitcoin.
02
Built for larger signatures
Post-quantum signatures are bigger. The protocol expands transaction capacity to absorb them — keeping fees low and blocks efficient as the network grows.
03
Public keys stay hidden
Pay-to-Merkle-Root (BIP-360) puts only a Merkle root on-chain — no public key to attack while coins rest. Post-quantum signatures secure the spend window.
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
