It may be appropriate to attempt to mitigate the extent of the freeze as much as possible, even at the cost of greater complexity, said BitMEX.
BitMEX Research has proposed an alternative to freezing quantum-vulnerable dormant Bitcoins, advocating a wait-and-see approach and a “canary fund” with a quantum bounty instead.
BitMEX Research proposed a soft fork on Thursday that would only activate a full freeze of vulnerable coins if it is “proven that a quantum computer capable of stealing Bitcoins actually exists.”
The system uses a “canary approach,” creating a special Bitcoin (BTC) address using a “Nothing-Up-My-Sleeve Number” (NUMS). This is a cryptographic proof in which the private key is unknown, but it is a valid address that could theoretically be spent by a powerful enough quantum computer.
