An idea on my mind on a dapp - offersworld.com, that would list all offers from local shops, validity, and will disappear after validity. So the dapp rewards hive to consumers, who buy through this ( some kind of authentication to make sure, they used the code from the site when they bought physically). So let's say, if we continuously reward consumers, then publishers ( local shops ) will be more and then adds can be built ( in fact designed from beginning). And offers may be shown based on user local.
What do you think ?
