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.

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\'s 6.7 million \'quantum minefield\' puts even Satoshi-era coins at risk
Dormant risks in the bitcoin ecosystem are resurfacing as analysis warns that advances in quantum computing could expose private keys. A Google Quantum AI paper estimates about 100,000 long-inactive dormant addresses may be vulnerable, holding about 6.7 million BTC. The study says assets could be attacked even while at rest using already-public blockchain information. Coins from 2009 to 2010 P2PK outputs are highlighted, and total vulnerable holdings could reach 6.9 million BTC.
