Avihu Levy, a researcher from StarkWare, has introduced a new method called Quantum Safe Bitcoin (QSB) that enables Bitcoin transactions to be resistant to quantum attacks without altering the existing Bitcoin protocol. This method replaces traditional signature-based security with hash-based proofs, which are designed to withstand quantum threats. However, the implementation of QSB requires extensive off-chain GPU computation, leading to transaction costs ranging from $75 to $200, significantly higher than the typical transaction fee of around 33 cents. QSB is intended as a last-resort solution while proposals like BIP-360, which aim to provide long-term quantum resistance through protocol changes, face delays in activation. Currently, the timeline for BIP-360 remains uncertain, with low odds of it being implemented soon. As quantum computing technology advances, QSB offers a way for Bitcoin users to protect their transactions today, albeit at a high cost and complexity, as these transactions cannot utilize faster systems like the Lightning Network and require direct processing by miners.
