Regulatory bodies, an engaged community of experts to provide scrutiny and reach out to journalists when there are problems. Like with cars, planes, and online banking, the key determinant is that nontechnical people have a _sufficient_ degree of trust in _someone_else_, who does have the appropriate expertise, to provide oversight. I have no idea if Agora is good or not, or if blockchain-based voting is viable. I'm just saying that there are demonstrated cases (and certainly also other demonstrated failures) in which nontechnical people trust experts and trust organizations to provide a sufficient degree of oversight. In a sense, you could say that a classroom, or a democracy, is like this too.
