I think it clearly is a kind of social credit score. But the words “social credit score” are so beaten up no one knows what the words mean. In this case a web of trust is decentralized. We each make independent choices about who we will trust and the outcome is you can see who the people you trust also trust in making the decision on who you will add for receiving services etc.
So It’s a lot like human to human trust. The problem with the “social credit score” dystopian scenario is that people aren’t choosing individually a central authority is choosing what you get. And that power will be abused and manipulated.
