"You cannot have those people from within the Hive network, since they would be in conflict with their interest. Since they are all stakeholders..."

I don't see any conflict of interest. Outside Hive every jury member uses fiat. Juries on Hive using it's tokens aren't any more of a conflict of interest.

Seems to me that would cause them to more diligently judge carefully their peers, zealous to both defend the innocent (to make sure they're not judged unfairly themselves if they are falsely accused) as well as get scammers and malicious parties cured or censored. That's the point of juries of peers: folks that have a vested interest in justice, not kangaroo courts or pats on the backside for hazards to the community.

No one would better be able to investigate scams and etc. than Hive members that are competent to use the features of the front ends and platform, and only in cases of actual crimes, like theft and fraud, would outside authorities be necessary to bring in. Frankly, like all insular communities, I'd prefer to handle our business in house.

By the time we get to mediation, we should have a good understanding of the facts of the matter, which a proper adjudication metric should provide appropriate guidelines to a jury to implement.
