Right now for example I'm lifetime positive against Caesars(the main conglomerate I gamble with) and another smaller casino. It would be linked and verified to your online nickname, and thus if you made a claim about winning a bunch or losing a bunch, people could double check in semi-real time if youre full of it or not. So the scenario I'm thinking of is that you'd have a very secure website where your Win/Loss statement could be verified for accuracy(so no photoshopping it) while also ensuring that no one can obtain your other information(name/dob/address/etc).
Had this shower thought and figured I'd ask here what your thoughts were.
