So, essentially a super cookie? That is, generated once (at random or arbitrarily) and then included with proof of work? But not a fingerprint or otherwise linked to identity?
But then that would not work against correlating fraud detection as sketched above. A client could simply reset the app every now and then to generate a new UUID.
