“A StarkWare researcher has proposed Quantum Safe Bitcoin, a hash-based scheme that can make bitcoin transactions resistant to quantum attacks today without changing the Bitcoin protocol. The method works within existing consensus rules but requires massive off-chain GPU computation, driving estimated costs to $75 to $200 per transaction and making it far more complex than standard payments. Framed as a last-resort emergency tool rather than a permanent fix, QSB contrasts with long-term proposals like BIP-360, which seek protocol-level quantum resistance but are likely years away from activation.” (04/10/26)
