https://citizens-initiative.europa.eu/_en, This is the initiative I am talking about. You have to prove you are an EU citizen and then you can sign for the initiatives you want and if a million signatures are reaching within a year then it must be brought to the EU commission.
So if citizens of EU member states can sign online, why can’t they vote online for elections or referendums? If possible, this would decrease the need and power of representative democracy and move closer to direct democracy, which I argue is a good thing
You could summarize the whole transparency thing into just one word: trust. As long as people trust that everything is fine, the society can continue to function. When people loose trust, everything falls apart.
If you can convince millions of people that the voting system works and is fair, you can have a democratic society. If not, you might want to look into alternatives such as totalitarian dictatorship, monarchy or even post apocalyptic absolute chaos.
