U°OS blockchain social trust network explained: the video 

Hi All! This video explains the network of social trusts. Trusts are allocated by the participants to each other on U°OS DApps (in particular, right now on our U°Community DApp). This network of social trusts is a critical protection from such botnets, that aim to increase their social rate by the means of activity imitation. Trust network generates input data for user validity computation. Validity contributes importantly to the social activity rate calculation. And, therefore, to the overall user DPoI score.
