Bitcoin Completes First Experimental Quantum-Safe Transaction, Starkware Says

Starkware reported it has completed an experimental, proof‑of‑concept quantum‑safe Bitcoin transaction using a quantum‑resistant signature approach. The demonstration shows that integrating post‑quantum cryptography into Bitcoin transactions is practically feasible but remains experimental and not standardized or deployed across the network. Widespread adoption would require consensus‑level protocol changes, wallet and infrastructure upgrades, and coordinated key‑management practices. The key implication is that Bitcoin’s ecosystem now has a concrete technical path to begin mitigating future quantum threats, but there is no immediate network‑wide protection.
