Bluesky is building a social protocol. We released “ADX” (the X stood for Experiment) in May. Now that the design is starting to solidify, we’re renaming it to the “Authenticated Transport Protocol” — the “AT Protocol.”

The AT Protocol is a new federated social network. It integrates ideas from the latest decentralized technologies into a simple, fast, and open network.
What’s a “federated” network? It’s a way for servers to communicate with each other – like email. Instead of one site running the network, you can have many sites. Users get a choice of provider, and individuals and businesses can self-host if they want.
What makes the AT Protocol unique:
🔶 Account portability
🔶 Algorithmic choice
🔶 Interoperation
🔶 Performance
🔶 Account portability
A person’s online identity should not be owned by corporations with no accountability to their users. With the AT Protocol, you can move your account from one provider to another without losing any of your data or social graph.
🔶 Algorithmic choice
Algorithms dictate what we see and who we can reach. We must have control over our algorithms if we're going to put trust in our online spaces. The AT Protocol supports open algorithms so users have more control over their experience.
🔶 Interoperation
The world needs a diverse market of connected services to ensure healthy competition. The AT Protocol includes a schema-based interoperation framework called Lexicon to help solve coordination challenges.
🔶 Performance
Many novel protocols don't prioritize performance, resulting in long loading times before you can see your timeline. We don’t see performance as optional, so we’ve made it a priority to build for fast loading at large scales.

You’ll find a few “TODOs” in the specs, but the technology is stable enough that we can start to communicate what we’re doing now. atproto.com
The World-Wide Web wouldn’t have been much fun if it was created without a browser, and the same is true of the AT Protocol. So we’re also building a Bluesky social app.

Looks like we've reached a temporary limit on mailing list signups right now - @SendGridSupport @SendGrid we need up upgrade our plan and your site is not allowing it
We pushed a temporary fix and then switched mailing list providers, so signups on bsky.app are working again.
Thanks for your interest! Excited to share more soon 🎉
