A quick technical review 🧵 on AT Protocol (Bluesky) and Farcaster. Both protocols have quite similar objectives, but they have very different design. First, identity. Both want account portability where user can migrate identity to a new service provider without existing server’s cooperation (unlike Fediverse).

ATP makes moderation and spam filtering easier because PDS and indexers are free to ignore some users when syncing. FC makes it easier to sync the world’s state, but spams may become a problem because there is no obvious way for Hub to selectively ignore some users. 15/n
