StarkWare Optimizes Quantum-Safe Bitcoin Transaction
Researchers have reduced the estimated computing cost of a specialized quantum-safe Bitcoin transaction by 82% to $59 through the StarkWare, Yukon Research, and Eigen Labs optimization challenge. The method, known as Quantum-Safe Bitcoin (QSB), uses hash-based cryptography and a computational puzzle to secure specially prepared Bitcoin holdings against attacks on conventional digital signatures. The $59 figure is based on simulated GPU workloads, not a completed production transaction. StarkWare aims to target a computing cost below $10 with further improvements.
