StarkWare: Quantum-Resistant Bitcoin Transaction Cost Falls 79% to Under $67

The headline is a cost-reduction milestone, not a deployment. What matters is that StarkWare is attacking the preparation step of a last-resort quantum-safe mechanism, where GPU economics have been a practical bottleneck. This is relevant to anyone tracking Bitcoin's long-term cryptographic contingency planning, though the experimental framing and the absence of a production timeline leave the path to actual use unclear. Whether these optimizations hold outside a weeklong challenge setting is the open question.
