Great and thorough analysis of attack vectors of early curation market designs and are the considerations that informed our design. As Vitalik concludes, identity is the ultimate solution, but I do believe there exists a design space for systems that work and have weaker identity requirements. Identity can be context depended, and a whole network of pseudonymous users can be built around a few strong identities. This is what the Relevant Reputation system enables. This concept is sometimes referred to as a 'web of trust'. If I trust you I also trust your close friends. I don't need to know your friends identities in order to trust them. We rely on this type of dynamic all the time in the real world. It won't give a strong security guarantees so you shouldn't rely on such a mechanism to safe-keep your crypto bags, but its perfectly suitable for low-stakes cases like content curation.

Reading about the Relevant betting and reputation mechanism reminded me about this post by Vitalik from last year He mentions both, betting on content with coins, and generating trustable reputation through other members of the community: "...where anyone can upvote or downvote submitted content, with content that is upvoted more being more visible..." Makes me pretty bullish on Relevant. What other research is there on this topic of token mechanics and reputation?
