Computer security and election experts have studied the feasibility of internet voting for over twenty years. A blockchain doesn't protect against the fraud of centralized elections. A strong legal system and well designed constitution can. A transparent blockchain offers no privacy of how a person votes. And how is that person represented on a blockchain in the first place? With a hexadecimal hash tied to a database? Whose database? Does everyone have to run a node to verify the data? What node software is required? If you can fit 3000 txs into a single block, and there's a block every 10 min, and you have 200M people voting, wouldn't that take over a year? And people have to pay to vote?
