To your questions, I don't know. I would think we would try to avoid 51% attacks by construction because the blockchain would not be easily accessible by non-voting machines. Voting currently doesn't do much to prevent imposters, so I wouldn't even try to addres that. It's also possible that voters would not even receive a transactions receipt (votecoin). They may not even be aware blockchain is going on behind the scenes: they may just see a normal voting machine at their precinct, beep-boop the screen and go home. The value would be in being able to audit the entire vote chain, which we currently don't do. Currently we spot-check the paper ballots against machine output for auditing. Re-doing the whole thing is a recount, and rare. My complaint about bitcoin itself is that rather than creating a virtual currency, we really created a virtual commodity; that is, it's the closest we've come to creating a virtual item that has the properties of scarcity and non-transferability of physical items. I think that's bad for a currency, but good for auditing votes.

Doesn't that defeat the point? Surely they should be able to run on public networks while honouring Kerckhoffs's principle: A cryptosystem should be secure even if everything about the system, except the key, is public knowledge. That's the whole mission here, no? > they may just see a normal voting machine at their precinct, beep-boop the screen and go home. The value would be in being able to audit the entire vote chain, which we currently don't do. But if there's no 'voter identity' in the system at all, what's stopping a malicious government from just synthesising the whole blockchain?

  > So we're trusting the voting machines? Maybe. I'm not married to much - I'm just defending that voting is one of the rare cases where I think blockchain has value. We currently trust the voting machines, so even if we do it with the voting machines, it's still an improvement on what we're currently doing. > But if there's no 'voter identity' in the system at all, what's stopping a malicious government from just synthesising the whole blockchain? Not much! So we either have to allow individuals voters to get a receipt and verify their votes (which can introduce problems), or we have to print paper receipts which are kept on site. Yes, those can be printed out as a bad actor synthesizes a new blockchain, but paper ballots can be faked, too. To me, the mission is creating an easily auditable voting record, which we do not have now.

    > We currently trust the voting machines Indeed, and that's a huge mistake. Should have stuck with paper ballot. The high-tech solution isn't always better. In this case, it seems pretty clear that it's far worse. The Diebold voting machines, for instance, have been shown to be a joke. I like Scheneier's idea that perhaps machines could have some value as supplemental machinery to a paper ballot https://www.schneier.com/cgi-bin/mt/mt-search.cgi?search=voting&__mode=tag&IncludeBlogs=2&limit=10&page=1 https://www.schneier.com/cgi-bin/mt/mt-search.cgi?search=vot... > I'm just defending that voting is one of the rare cases where I think blockchain has value > the mission is creating an easily auditable voting record I don't see any link between these two.
