What is Quantum Safe Bitcoin (QSB)?

QSB is a hash-based scheme for quantum-resistant Bitcoin txns on the live chain, no fork needed, using heavy off-chain compute.

How much does a quantum-safe Bitcoin transaction cost?

$75-200 via cloud GPUs, vs. 33 cents normally – for emergency protection only.

Does QSB work with Lightning Network?

No, it's legacy-chain only, direct to miners, no L2 compatibility.
