Believe it or not those are all solved problems
The largest blockers to implementing them for voting are no longer technological, they’re political
We can absolutely cryptographically verify your voting choice from your phone, and have you and everyone be able to verify when it changed, where, on what device, etc, while also preserving the anonymity of the voter.
(Edit: while also making it far easier to combat fraud by making elections trivial enough to go “ok, everyone go check and resubmit your choices!” And immediately validate the majority of the votes as valid, minus those who don’t have internet access who would still need to travel)
Problem is, there are a lot of very powerful organizations who would suddenly lose much of that power if voting were in any way convenient and accessible to everyone.
Every time someone confidently claims that we can cryptographically verify voting, they are deliberately or ignorantly keeping the complexity and necessity of verifying the verifier runtime, the data source, and the communication channels out of the picture.
Cryptography doesn’t solve voting verification problem, it obscures and shifts it.
Rando there is really talking about about putting elections on a blockchain and trying really hard not to say the word.
OK, cool now teach your family that calls their web browser "The internet" enough computer science to adequately understand and audit this proposed open system and convince themselves that their votes are counted in a fair, verifiable and secret manner. Also that the implementation does not have obvious side channels and what is actually running is built from the published source code.
Like, If I was part of some shady powerful elite I'd love a fully automated setup. Most people will not be able to check the system deeper than "phone displays green check mark" without an unreasonable time investment.
On the other hand, "room full of people opens box full of papers and counts them while verifying each other" is intuitive enough for almost anyone to grasp and gain confidence in.
You may be able to verify that a given code is correct, or that a given device is correct, but no amount of software can conclusively prove that a given person has voted. All that cryptography prevents is a man in the middle attack, it does not prevent bad inputs from being entered by people who have stolen credentials.
Voting should be easy and convenient, but paper ballots and voting booths can be easy and convenient.
