I'm not familiar with "Blockchain Research Institute", so I'm not sure if your comment is critical of them as an organization or not. I am also wary of the blockchain-is-magic hype train, so I generally agree with your assessment that we aren't prepared to vote online.
While I wasn't surprised by the overall lack of technical details given the medium/audience, I did find it odd that the question of privacy was essentially ignored. Do they have a solution in mind that allows me to validate that my vote is in the ledger without the vote being traceable back to me?
