I ask this every so often during threads regarding stolen cryptocurrency: Is there any solution yet to preventing stolen cryptocurrency funds from being spent? Isn't the only solution to have a central database and require laws to require every transaction to be pre-checked to see if it's stolen funds or not?

What does "stolen cryptocurrency" actually mean?

It's the same decision process as the normal justice system. Broadly speaking, you can analyze it as follows (for civil complaints):
1. Is there a clause in the contract that says "disputes follow XYZ jurisdiction"? Then that's the jurisdiction. (And adding such a clause is Contracts 101 material).
2. If not, then you can usually get jurisdiction based on where the offense actually happened, or where the defendant lives. The analysis can get complicated, but it's not going to meaningfully change for cryptocurrency.
3. There's also a potential for extraterritorial jurisdiction in some cases.
> What if that's not recognised by a different jurisdiction, or someone else comes to the opposite conclusion?
Well, jurisdiction really comes down to a) can you get a court to agree that it has jurisdiction, and b) can you get other people to agree to the court's orders for relief.
