If you go to grapevine-brainstorm.vercel.app you can calculate personalized PageRank and personalized GrapeRank scores and export them in a format (NIP-85) that is easily accessible by clients. The about section tells you a little about it.

NIP-85 is new. I don’t think anyone clients are using it yet. But hopefully they will soon!

Work in progress:

1. personalized grapevine WoT relay that calculates those scores for you, stores them using NIP-85, and uses them to filter data that you keep on your relay. It will use strfry and neo4j, the most mature FOSS graph database that I am aware of.

2. Contextual GrapeRank scores, so your trust network can tell you who are the world’s most trustworthy sources on any given topic.
