Private keys don't add much to voting. It's the same issue that blockchain people tried to apply their chain to voting. It's cool. But it doesn't solve much.

The I.R.S.?! Social security numbers? You still trust the government? Study history and you may learn that voting has been fraudulent from the beginning.

Elections and "just electing the right people" aren't going to save us. View quoted note →

The govt agency in charge of "verification" would just become suddenly extremely powerful. No way to sprinkle cryptography & suddenly make centralized shitcoin like architechture fair & just.
