While I am not optimistic on NFT-Fi, I see potential for NFT OTC/Brokers. This is a graph of every Cryptopunk sale, and the "yellow" sun is Punks OTC. Their "page rank" score is 10x higher than any other address, indicating their importance

Is the edge of the graph money transferred? Is that a good way to run page rank where the edge refers to transfer of reputation from an authority?

Edges are individual transfers instead of amount. I think it’s a good way as you could see who is a potential Sybil. What are your thoughts?

To me the definition of the nodes and edges are more important.

You can define different types of edges (heterogeneous information networks)

You can have different strengths/values for each type of edge

You can also choose different type of matrix algos - pagerank only focuses on Authority vs similarity
