"Blockchain Technology" has attracted scoundrels of every stripe. If Agora really cares about this as a test case, it needs to make the voting records public, and articles like this one need to make it clear how the reader can examine the results.

In Bitcoin, the answer is crystal clear: Proof-of-Work coupled to an economic incentive. This system has well-known scope and limitations. We can reason, mathematically, about a multitude of attacks and outcomes.
Not so with the Agora system. And I'm afraid that journalists consistently refuse (or are not equipped) to ask the right questions - as in this article.
