I imagine a opinion poll on top of UBIC, where people can pseudonymously cast a reliable vote for example on future presidental candidates - or on the question: brexit yes or no.
It would create for the first time reliable internet polls - those on top of ubic cant be tricked that easy using bots or fake identity - and cant be faked by the instance itself that started the internet poll question in the first place.
People just need to register to ubic and every casted vote is expressed in a tiny transaction to a burning address, which is read out by the app as a vote for or against something, whatever question was asked.
Regarding anonymity against the state: people wont care too much about it if it comes to topics like brexit or presidency.
