This looks like a premature assessment. The problem with voting systems are many, and so are the benefits and ways to apply blockchain tech. There are other examples in different comments already, but the most glaring prematurity here sounds like some sort of comparison being made to crypto currency. I honestly don’t understand why you’re doing that or the point you’re making.

For one other example so far unmentioned, mere distribution of public keys (not reliance on them) along with open source decentralized blockchain is grounds for verification far beyond what we have now, which lingers near the zero mark. Why would we complain about that?
