A GitHub repository presented Quantum Safe Bitcoin, or QSB, a transaction scheme designed to keep Bitcoin secure against a large-scale quantum adversary without requiring a soft fork. The project says it works entirely within Bitcoin’s existing legacy script constraints and consensus rules.
The design replaces Bitcoin’s usual ECDSA security assumptions with hash-based ones. In the repository’s description, QSB uses a hash-to-signature puzzle built around RIPEMD-160 and a HORS-like one-time signature scheme, while keeping the logic inside current Bitcoin script limits. The tradeoff is cost and complexity: the repo estimates about $75 to $150 in cloud GPU compute per transaction, and says the transaction would be non-standard, requiring miner-direct submission rather than normal relay.
What makes the proposal interesting is that it sketches a fallback path Bitcoin could use without waiting for a protocol change. At the same time, the compute bill and relay limits make QSB look far more practical for exceptional or high-value transfers than for ordinary daily payments.
