Ring signatures -based mixers for voting seems like a bad idea... how do you solve vote selling?

  If you want to go all the way, you can make a system where you can’t prove how you voted. But you can check using ZKP that your vote was counted in the final result. https://medium.com/edge-elections/what-is-a-zero-knowledge-proof-aebe33cb47af https://medium.com/edge-elections/what-is-a-zero-knowledge-p... But out of curiosity, what exactly do you imagine happens in vote selling? Someone pays off each individual in half the population to vote a certain way? How do they do this at scale and how do you know it isn’t more cost—effective to just influence them? Most people who voted for Biden instead of Bernie ahead of Super Tuesday made up their minds on the way to the polls. Biden wouldn’t have even won if nearly all the other participants wouldn’t have dropped out and endorsed him. He was losing badly to Bernie (and Pete) but as soon as he managed to prove electability in one state, all the other candidates fell on their sword. It’s like in a poker tournament where the chip leader loses to some guy who isn’t even 2nd or 3rd because everyone else stands up and gives him their chips. And also, there are trade offs the other way. There are tons of failure modes in voting non electronically.
