What is Quantum Safe Bitcoin (QSB)?

A transaction scheme using hash puzzles to mimic ECDSA signatures, making BTC sends resistant to quantum attacks without protocol changes. Costs $75-150 per tx.

Can quantum computers crack regular Bitcoin now?

Not yet—needs millions of qubits. But Google's recent paper slashed estimates, putting real threats 5-10 years out.

Does QSB fix all Bitcoin quantum risks?

No, skips exposed P2PK wallets (1.7M BTC). Best for new, large transactions; protocol upgrade needed for full armor.
