If you own Bitcoin today, you’ll be able to claim an equal amount of QBTC, a new coin built to survive quantum computers that could otherwise steal Bitcoin. Bitcoin’s signatures will eventually fall to quantum computers. QBTC is the safe harbor: a new chain that runs on quantum-resistant cryptography from day one and already knows your Bitcoin balance. You move on your own schedule. Your Bitcoin stays on Bitcoin.Documentation Index

The core idea, briefly
Quantum computers will eventually break the math that protects Bitcoin addresses. Every Bitcoin address whose public key has ever been revealed (which includes every address that has ever spent) becomes vulnerable that day. QBTC is a separate chain built on quantum-resistant cryptography (a NIST-standardized scheme called ML-DSA). The chain keeps a continuous mirror of who owns what on Bitcoin. To move your balance over, you prove you own your Bitcoin address using a zero-knowledge proof, a cryptographic technique that confirms ownership without revealing your public key. The migration itself is therefore safe from quantum attack. Nothing happens to your Bitcoin. No bridge, no peg, no locked coins, no custodian.The same Bitcoin. Ready for what’s coming.
