Elon Musk's Pravda

What about trust?

Is there any formal proof (scientific paper) on the possibility of creating a "true" voting system? By "true", I mean that one can mathematically prove the correctness and fullness of the public data (ledger).

We created the zero-knowledge proof a long time ago. Why we can't create a reliable system for anonymous voting/social polls?

Because he is silly. Pravda is similar to Polish word Prawda than means truth. Truth is very difficult to establish outside science.

  - People are biased in many different ways.
  - Modern propaganda can use true facts to build any public perception. 
  - You can have contradictory facts about same events
  - Cognitive dissonance has the stronger effect than people think.
  - Sometimes lies are needed because the truth is not something people can deal with
  - Perspective is different between genders/race/religion etc

An incredibly difficult social problem not technical. Wikipedia tries to build a system like that and it far from a success.
