[Bitcoin Core Developer Proposes Quantum Attack Collateral Defense Solution] BlockBeats reported on November 7th that Bitcoin Core developer Cory Fields proposed a "quantum mine" solution, attempting to increase the cost for future quantum attackers to steal Bitcoin from old wallets through a collateral mechanism. According to the proposal, transferring Bitcoin vulnerable to quantum attacks would require additional collateral and a waiting period. The legitimate holder could then retrieve their assets and obtain the attacker's collateral by presenting a pre-prepared secret proof of ownership within the waiting period. The report points out that because the blockchain cannot distinguish between attackers and legitimate holders, the latter would also need to provide collateral when transferring such Bitcoin; for dormant assets whose private keys have been lost, Fields also proposed an auction mechanism that could be challenged. This solution is still a proposal and not an implemented network rule. (BeInCrypto) [Original Link]
