assuming that "who follows npub X" is a query i can run on relays. will have to check docs...
Discussion
Should be able to just query the follow list of any npub.
NIP-01 isn't entirely clear about how filters work. i see that you can filter on "p" tags, which are what are used for follows, and you can also filter on "kind" for events, so if you filter for events of kind 0 (profile metadata) that contain a particular p tag (npub), maybe you get back all the profiles that follow npub on that relay?
It's going to matter which relays you query for an npubs followers though. You'd have to round-robbin across all known relays to get to the truth. Like nostr.band shows about 100 more followers for me than Iris does, since they're querying different relays.
yeah, i'm totally thinking about all of the implications, having just implemented a tool that checks nearly 400 relays just to figure out where *one* post reached.
I've been using this one to see how quickly my notes propagate across the network from a blastr relay like mutinywallet: https://nrcheck.tigerville.no/
I think that’s thor’s lol.
LMAO I couldn't remember who made it. There was another one I saw yesterday that wasn't as good as this one.
i bet you're not the only one who missed that it says "Thorwegian" right on the page 😆
its read operation x multiply how many using / hour
