I think e-voting works in Estonia(?) and was tested in few countries (Finland, France, Netherlands?). I'm just imagining... Each citizen will receive z-address (wallet and privite key can be generated only by goverment) and in the election weak each citizen will receive 1 coin and according to who they want to elect, they send this coin to the specific t-address (transparent). So that way everyone can see how much votes the candidate has but noone can tell who voted him. This is my simple idea that can be improved in many ways.
Thank you for movie recommendation
