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).

However, it means that ATP users either have to run their PDS in a home server, or look for a service provider that run it for them. Either way is a friction to user adoption. 13/n
