I want to know why, with a digital currency like bitcoin, the stolen coins cannot be identified and blocked from use. If the stolen coins could be disabled, then new coins could be automatically reproduced and restored to funds? Why does each coin not have a fingerprint of sorts? Maybe if this idea is antithetical to bitcoin, then another company could create a competing product that was in such a way theft proof, high insurance, etc.
Just wondering.
Who decides that the coins are stolen? Maybe if I don't like you (or we are competing bidder to acquire a company) I just claim stolen block your coins and later say "oops terrible mistake".
Or I spend my coins and get the product. Next I claim the coins are stolen. Get new coins & keep the product.
Suddenly all the coins in your account are unspendable. You bought them from a reputable exchange so WTF? Well, someone just noticed that they were stolen from their wallet a week ago. They've gone through about 50 people between then and now but you are the bag holder.
Its just unworkable. Best to identify the thief and possibly throw him/her in jail, and extract not the exact coins but equivalent value from the thief through normal means.
