Re: Any way to block usage of stolen coins?

Let`s us say that a exchange got hacked, Would there be anyway to ban those bitcoins? like blacklist the stolen coins so they cannot be used on the network? I know about going back in time with consensus of the network to a earlier block or forking and using that new chain, but could you just not ban the stolen coins? I mean make a way to do that?

If the new address was known, exchanges could blacklist the addresses. But eventually, the culprit could find a way to offload the coins.

I am talking about the bitcoin network blacklist the coins, not the exchange.

They couldn't blacklist the coins even an exchange couldn't do something about it but if you'll report and prove the occurrence of a certain hacking incident, some exchanges could ban an address. You must report an incident right away to an exchange's support for them to do a proper sanction.
