First quantum-resistant Bitcoin transaction successfully executed, StarkWare says

StarkWare announced it executed what it says is the first quantum-resistant Bitcoin transaction. The company used a post‑quantum signature scheme to sign, broadcast and have a transaction accepted by the Bitcoin network, demonstrating technical feasibility of post‑quantum signatures on Bitcoin. This proves a pathway for mitigating future quantum threats, but broad protection will require standardization, wallet and node upgrades, and coordinated key‑management because the ecosystem still predominantly relies on secp256k1 keys. The key implication for Bitcoin is that migration to quantum‑resistant primitives is achievable in practice, though adoption and compatibility remain the main hurdles.
