StarkWare researcher proposes way to block quantum attacks on bitcoin without soft fork
A StarkWare researcher has published a paper proposing a way to protect bitcoin transactions from quantum-computing attacks without a soft fork. The paper introduces “Quantum Safe Bitcoin,” or QSB, which aims to add quantum resistance using only existing legacy script constraints. It replaces elliptic-curve cryptography with a Binohash-based structure using one-time signatures and a new hash-to-signature puzzle. The author said the approach is costly, at about $75 to $150 per transaction.
