No there aren't. If you can check your vote, then your abusive spouse, your boss or somebody else who has power over you, can force you to show them your vote.

Not neccessarily, you can have a system where you can retrieve 'proof' of having voted in any way you want, and you can verify via some secret information used when voting, but making the UX of such a feature good enough that it's actually usable by someone in those circumstances is not at all easy.

Voter goes in to vote.

They are given two random words. One for candidate A, one for candidate B.

They are told they should remember the code-word matching their choice if they later want to scan the printed out QR code (or enter their vote uuid) to one of the validator websites.

Voter makes their choice, completes the process. A thermal printout is printed with their vote uuid and a QR code meant to make it easy to input it.

Now anyone can get that printout with the uuid and scan it and see the code-word representing the voter's selection. However the association is only known to the voter and if asked, the voter can say that's what it was.

Nice to read this.

I've been thinking for a while that it would be nice to have paper ballots with the ability to cryptographically verify the inclusion of your vote in totals all the way up (ballot collection box, polling location, district, city, county, state, nation).
