Avihu Levy, the chief product officer at StarkWare, has proposed a Quantum Safe Bitcoin (QSB) transaction scheme that could protect Bitcoin transactions from quantum threats without necessitating a soft fork. This method, published recently, ensures security against adversaries using large-scale quantum computers running Shor's algorithm. The QSB scheme operates within the existing Bitcoin script constraints and replaces the traditional proof-of-work signature puzzle with a hash-to-signature puzzle. However, it comes with significant costs, estimated between $75 and $150 per transaction, making it unsuitable for routine transactions. The Bitcoin community is currently divided on how to handle potential quantum vulnerabilities, with some advocating for protocol upgrades while others consider this proposal a temporary fix. Notably, concerns remain regarding dormant wallets and public keys that may still be vulnerable to quantum attacks. Despite the potential of the QSB scheme, researchers emphasize that protocol-level changes are the preferred long-term solution for ensuring Bitcoin's security against quantum threats.
