Voting is one of the most popular example to illustrate the potentials of Blockchain and Smart Contracts. Voting is a use case that is well aligned to the unique propositions of Blockchain technology.

Basic Principles of Voting

According to the Equal Justice Foundation, the 6 principles of voting are as follows.

1. Secret Ballot: Your vote is secret. Nobody should be able to link your vote back to your race, gender, age and personal profile.
2. One man, one vote: Every voter votes once and the voting system must be able to reconcile the total number of votes to the total number of voters and those who did not vote.
