Bitcoin Core developer Cory Fields proposed a system called "quantum landmines" to protect wallets vulnerable to quantum computer attacks by requiring anyone spending such Bitcoin to post collateral equal to the coins' value. This collateral could be claimed by original owners who had prepared proof of ownership, discouraging theft by making attackers risk losing their own funds. Fields also suggested auction mechanisms for dormant wallets whose owners may have lost keys, aiming to make theft less attractive. The proposal is theoretical and would need new quantum-safe Bitcoin outputs and consensus rules before implementation.
