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.

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.

01

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.

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
  • Native dilithium-bech32 and dilithium-legacy address formats
  • Cryptographic agility — ready to adopt new NIST PQC standards

Get involved

Three ways to join the network.

01 · Miners

Run a node, mine quantum-safe blocks.

Help secure the network and earn testnet BTQ. Same SHA-256 proof-of-work Bitcoin miners already know — with post-quantum signatures riding on top.

Quick start
02 · Developers

Build wallets, tools, integrations.

Bitcoin Core's UTXO model and scripting system, extended with a clean RPC API for post-quantum signing. Familiar surface, new primitives.
