The Bluesky team has an academic paper describing the protocol that’s a pretty good high level but somewhat technical overview. It includes how they see Bluesky compares to Secure Scuttlebutt, Nostr, Farcaster, and ActivityPub/Mastodon.

I think folks who are building Nostr apps or advocating for it in comparison to Bluesky would do well to read it to understand what they’re doing and how we’re different.

We should also write up one for Nostr.
