You have a seperate blockchain that is used to verify a citizen. You can put many things there (marriage status, SSN..not needed anymore with this, any other info), which would include a voting key. The voting blockchain would check the citizen ID blockchain, to verify that citizen and all ensure the same voting key would not be used twice and that the citizen has proper status (like...is the person alive...legal...not a current felon, etc.) Theoretically, we have figured out the entire thing pretty damn well, we just need someone to try it ;) Also, explaining blockchain to the general population and "assuring" them will be the hardest part. People will revolt and think it's rigged and have no understanding of how it works. Even politicians are clueless...so, yeah, not sure how far off we are on this hah.
