AI Agents Cut Quantum-Safe Bitcoin Transaction Cost to About $67

The significance here is less about the dollar figure than the mechanism: an open contest with AI entrants compressing a cost estimate that had been treated as a fixed constraint. If post-quantum migration costs fall this way, the calculus shifts for everyone holding long-lived Bitcoin exposure, since the barrier becomes engineering effort rather than prohibitive expense. What remains open is whether contest conditions translate into production-grade, verifiable quantum-safe transactions, and whether this cost curve keeps bending outside a competitive setting.
