A week of AI coding cut a quantum-safe bitcoin transaction estimate from $320 to $66

AI-assisted development reportedly reduced the estimated cost of executing a quantum-safe Bitcoin transaction from $320 to $66 in about a week. The result suggests that optimizing post-quantum cryptographic implementations and transaction design could materially lower the cost of upgrading Bitcoin against future quantum threats. However, the figure is an estimate, and broader deployment would still require rigorous security testing, network-wide coordination, and protocol changes.
