      You might want to look into Quorum and Constellation, two foundational tools in an emerging field of permissioned blockchains that preserve privacy as a first class feature.https://github.com/jpmorganchase/quorum …

      Sorry, but I just spent fifteen minutes trying to find a specification of the Quorum protocol, with no luck. Can someone point me in the right direction so that I can actually assess its (unspoken?) correctness and security properties? /me not impressed so far

          Are you trolling me Dan? ;) I know *you* know what a protocol specification is, but do they? There isn’t one in that directory, or repository, as far as I can see. I did find this IACR paper about integrating ZK, FWIW. https://eprint.iacr.org/2017/1093.pdf

          haha! sorry :-x. Considering the pace of development, it may be more useful to speak directly with the developers. I'm sure @AmberBaldet can put you in touch if you're interested. Having spoken with them myself, the topics you're interested in are top of mind for their team.

          Oh hi Joe :) The privacy model is documented but not formalized yet. Briefly, it's just NaCl secretbox/box of tx contents shared only with intended recipients. Happy to describe in more detail.

          For the record I don't think anyone should be doing any kind of elections using any kind of blockchain (or computers...) *cough* Denmark *cough*
