There are a lot of stories of stolen bitcoins from hacked websites or fooled people.
I was wondering, since all transactions are in blockchain, is it technically possible to make blacklist of wallets where stolen funds where transferred (by claims of victims) to track transfers of those funds and report when the owner can be identified (for example when some goods where bought and delivery address is known)?
Or perhaps just block those blacklisted wallets and don't support them on the network (bitcoin) level?
You can possibly track regarding on those coins on where it has been moved to other address but if the hacker or scammer use mixer then for sure tracking would really be impossible since it have been mixed which its impossible for you to follow the track and also blacklisting is only possible if some service or exchange but I don't think that they would really bother.This is when bitcoin have been stolen it would really be hard to traced whos the owner.
