> cryptography to the electoral system can be rooted in the pragmatic AND be abstracted to a layman

what you're arguing for is a system that you understand and can verify, but not other people.

You're also missing the bigger issue which is that voting systems vary by state, which means to do what you need to do would require federal/constitutional change.

Plus how do you verify and guarantee the terminals are not tampered with (especially as they are all going to be digital, and securing hardware in remote locations is fucking hard. )

Much as its not fun, paper votes with local counting stations are harder to corrupt universally (unless you have government collusion)
