Bitcoin developer proposes quantum-attack collateral system

Bitcoin developer Cory Fields has put forward a proposal that would require future quantum attackers to post Bitcoin as collateral before they can touch vulnerable wallets. This setup would give prepared wallet owners a window to recover their coins and then collect the attacker's collateral as a penalty. The idea is designed to make quantum attacks economically unappealing by turning the cost of a successful attack into a heavy financial loss for the attacker. Why it matters: as quantum computing advances, the Bitcoin network needs proactive defenses that protect users without requiring a hard fork or massive protocol change.

Would you stake Bitcoin to secure your wallet against quantum attacks?
