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).

In ATP, user handles are DNS names that resolves into DIDs. Contrary to popular belief, DNS is an okay option as decentralized identities if you accept that ICANN’s multistakeholder governance model is sufficiently neutral. The problem of DNS is more about UX. 5/n
