Bitcoin developer proposes ‘landmines’ to make quantum thieves lose their own BTC

A Bitcoin developer has put forward an innovative proposal, metaphorically termed 'landmines,' aimed at deterring and penalizing future quantum computing attacks targeting Bitcoin holdings. The core concept revolves around a mechanism designed to protect potentially vulnerable bitcoin from being stolen by quantum adversaries. Under this proposed system, any entity attempting to move bitcoin that is considered susceptible to quantum compromise would be required to commit a matching amount of their own collateral. The ingenious aspect of this 'landmine' strategy is that it provides a unique window of opportunity for the legitimate and prepared owners of these vulnerable bitcoins. Should a quantum thief initiate a move of such funds, the original owner, being aware of the 'landmine' protocol, would have the ability to claim not only their original bitcoin but also seize the collateral posted by the would-be quantum thief. This creates a significant disincentive for quantum attacks, transforming a potential theft into a costly endeavor for the attacker, and potentially a gain for the original owner who has prepared for such a scenario. This proactive security measure is a forward-thinking attempt by the Bitcoin development community to address hypothetical, yet potentially catastrophic, threats posed by advanced quantum computing capabilities against current cryptographic standards underpinning Bitcoin. It highlights ongoing efforts within the Bitcoin ecosystem to ensure long-term security and resilience against emerging technological challenges.
