I compared the architectures of AT Protocol (Bluesky) and ActivityPub (Mastodon, etc.)

You can see the tradeoffs between complexity and:

  • The ability to get a global view of the network.
  • Having nothing tied to your server: your identity, moderation, and feeds being independent from your instance.
  • Avoiding individual servers being flooded with traffic.

As always, all benefits have a cost and nothing is free. Which protocol is better depends on your goals. I’m really excited for both.
