Bitcoin \'Quantum Mines\' proposal seeks to deter quantum hacking by forcing attackers to post collateral
A new defensive concept has been proposed to prepare for potential bitcoin hacks using future quantum computers by forcing attackers to post bitcoin as collateral. The idea would lock both the targeted coins and the attacker’s deposit during a dispute window, allowing the original owner to reclaim funds if they can reveal pre-registered proof. The proposal also outlines two auction methods for vulnerable wallets, though it remains at the thought-experiment stage and would require changes to Bitcoin’s consensus rules.

Bitcoin proposal aims to deter quantum hacking by forcing attackers to post collateral
A new defence concept has been proposed to prepare for potential bitcoin hacks using future quantum computers by requiring attackers to post their own bitcoin as collateral. Even if a quantum computer recovers a private key from an old wallet, the design would impose additional collateral and a challenge process so that a successful hack could result in losses for the attacker. Bitcoin developer Cory Fields proposed \'Quantum Mines\' and two auction methods as a thought experiment rather than a finished design.
