> I've seen many proposed implementations but they all fail because if I can prove my vote to myself in any way, someone else can make me prove it to them either to buy or coerce my ballot. There is a way to prove that your vote was counted without being able to prove what you voted for by using homomorphic encryption. So, if someone wanted to coerce you or pay you for voting at all for whomever you want, they could do it, but that's fine. Microsoft is actually working with Galois on a system operating on this principle[1], and here's a good video explaining the basic concepts of how it works[2]. [1] [LINK] [2] [VIDEO]
