I like the idea of a personal relay, maybe encrypted and hosted which means I can access it anywhere, maybe also backed up locally so I don’t have to trust the hosting service with my data.

This would interface nicely with the Grapevine. There will be a csv file that stores an array of Influence Scores for each user & for each context I care about. A hosted relay could run scripts to update Influence Scores in real time even if I’m offline. Or if I don’t want to trust a hosted relay, I can run scripts locally to update Influence Scores and store them locally in my relay when I’m online.

If my Influence Score csv file gets too big, I delete an ignore Influence Scores in contexts I don’t care about or for any score whose certainty is below some threshold (no sense recording that Bob has a high trust score in some context if my certainty in that score is minuscule bc it’s based on scant data.)

A nostr client proxy is a far bigger project than a nostr relay. A nostr client proxy would have to have all the low-level code of a nostr client, which is probably more than 10x as much code as a relay needs.

So technically yes it could be extended into that, but the extension would be far larger than the current chorus relay is.
