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).

Next, the network architecture. Both protocols want to offers some level of censorship resilience, and both assume that apps need to ingest all content in the network to provide useful functions such as content discovery (algorithms) and user search. 9/n
