Researchers have cut the estimated computing cost of a specialized quantum-safe Bitcoin transaction by 82% to $59. However, the estimate comes from simulated GPU workloads rather than a completed production transaction, and Bitcoin network fees are separate. Quantum-Safe Bitcoin (QSB) could protect eligible holdings without changing Bitcoin's underlying protocol, but QSB requires direct submission to miners willing to process nonstandard transactions. A Glassnode study found that approximately 6.04 million BTC, or 30.2% of the issued supply at the time, had public keys already visible on-chain. QSB cannot protect already-exposed holdings unless owners complete a secure migration before a capable quantum attacker emerges.
