A proposed solution to the threat of quantum computers compromising bitcoin's security involves deploying 'landmines' that would penalize malicious actors. The concept, put forth by bitcoin developer Sergio Demian Lerner, would require anyone attempting to move vulnerable coins to also post matching collateral. This would give owners who have taken precautions a chance to seize both the vulnerable coins and the collateral. The goal is to make it too costly for attackers to use quantum computers to steal bitcoin.

This proposal aims to counter the risk of quantum computers breaching bitcoin's security by making it economically unviable for thieves to act. The idea could be incorporated into the next bitcoin protocol update, although it would require consensus among developers and miners.
