The restored subject must have previously been declared legally dead. For a positive resolution, the restored subject must be awake, be able to communicate, and live for at least one month. They also must have been declared dead for at least one month. The resolution criteria of this market will not be dependent on whether the restored subject retains their personal identity/memories.

@Adam The question doesn't specify how long someone has to have been cryonically preserved. Being cryopreserved with 2070s technology (or the latest technology before cryopreserved people aren't legally considered dead, if that's sooner) and revived with 2090s technology seems quite plausible.
@dph121 it's an interesting question what technology might exist, it might not even be cryogenic, but legally dead heart stopped etc for a month and brought back, wonder what's possible
