Bitcoin Core developer Cory Fields has proposed a “quantum landmine”: anyone wanting to steal Bitcoin using a quantum computer would first have to put up an equal amount of Bitcoin as collateral.
According to PANews, under the proposal, the original owner could set up a hidden proof of ownership in advance. During a lockup period (such as 30 days), they could use the proof to reclaim their Bitcoin and confiscate the thief’s collateral. Attackers would not know which holdings had a “landmine” until after putting up the funds.
· The proposal applies only to owners who still have their private keys; Bitcoin with lost private keys is excluded.
· For inactive wallets, Fields also envisions an auction system: competitors could secretly place bids in advance by staking funds against vulnerable wallets. If an attack occurs, the highest bidder’s smart contract would activate automatically, destroy the thief’s target coins, and confiscate the collateral as a bounty.
At present, which category has fewer safeguards under the proposal: holdings whose owners still have their private keys, or those with lost private keys?
