Did I understand correctly, that final user of information, provided by experts will be at the same time moderator? Or, how to deal with information that is mistakenly wrong, for example.
During the earlier days, we will have to moderate content by ourselves. After a while, we will gradually transfer these responsibilities to Experts with high enough rating, so the moderation will become self-regulated (like in Wikipedia).
Did I understand it right that with this system the possibility of posting deliberately wrong information (for promotion of particular ICO) is excluded?
And what about about authors? Is it possible for them to publish false information through their channels of information
With moderation, it is more or less excluded (also see our WP or previous answers to learn about attack protection). Even if somebody posts wrong information, they wouldn't gain a high enough rating easily to propagate that information.
As for the Authors, it is possible for them to post wrong information, but we encourage the Authors to make their widgets open-source and as transparent as possible. After all, it will increase popularity of their widget and increase their revenue so they are incentivized to do that.
