    I didn't understand what this was until I did some more digging around.

    Apparently, it's a decentralized way to interact with social media. A protocol created by Bluesky which allows social networks to communicate directly. This is similar to how different email clients like Gmail and Outlook can send messages to each other.

      Yes, but to nitpick slightly: the focus of this protocol is to let people use their own data with social media sites. It might not matter much while the site is active, but separating data ownership from the site makes moving platforms in the future much, much more feasible. Data like posts, friends lists, block lists, likes, comments, etc.

      Obviously, this was informed by people's experiences with Twitter, especially the early power users who built strong communities and then felt trapped.

    The summary of what this is about is:

    "Atproto is a big-world open social protocol. Users publish JSON records into repositories. The changestreams of those records then sync across the network to drive applications."

    It's too bad that information isn't on the front page. You have click "GET STARTED" and scroll down

      Is it really, at the end of the day, a server that serves your data over JSON (aka a social media post) and offers feeds (ala an RSS model) of the changes of that data and provides services for discovering the schema of that JSON (aka its lexicon)?

    I often wonder if people have forgotten that you can send information through the internet without HTTP(S)

      You can, but every non web protocol would need the user to install a binary. This is gated by Microsoft, Google and Apple today.

      If you ever want to implement a protocol in the browser it has to be on top of HTTP, WebSocket, WebRTC, WebTransport, etc.

      Since others starting intercepting and eavesdrop on non-authenticated traffic, it got a lot less comfy to do so though. It's not like people are adding encryption to stuff for the fun of it.
      • mghackerlady 3 hours ago
        it's not impossible to implement encryption elsewhere, gemini pretty famously requires it
        • embedding-shape 2 hours ago
          Of course not, the context here is ATProto which literally stands for "Authenticated Transfer Protocol", and it uses other protocols than just http/tls, so of course there are other ways :)

        it seems the parent comment isn't referring directly to encryption / TLS, but building everything on top of HTTP / HTTPS, which seems to be the default abstraction these days to build on top of.

          I agree, it is always HTTP nowadays. The Librecast project [0] is doing interesting R&D around multicast and social networking, and has been / is being funded by multiple NLnet grants over the years. I think they have plans to use ActivityPub to demonstrate their work. Current active project is LibreCast Studio, a collaboration environment. The linked video on the page is a very interesting watch.

      I assume for anything else someone will run into firewall/proxy issues.
      • thesuitonym 1 hour ago
        That's such a non-issue, though. And using HTTP doesn't guarantee you won't run into firewall/proxy issues.

    I think it would be interesting if the file servers had read/write/list/delete permissions on files. For both groups and users.

    It would mean the public stuff could see your files but private projects could exist. Eg. Maybe I don't want my At Protocol version of Figma making all my drawings public. If they could be shared in a group (anyone in a list in that folder or whatever).

    Maybe this is coming, but would interest me way more about using applications on the atmosphere.

      The ability to make information private fundamentally conflicts with how ATProto is designed. All records have to be sent to all Relays and AppView nodes on the network to provide a "global view" of the network. So there's no way to keep records private without locking out some user's servers from viewing them, and since AppViews are centralized indexing services, they won't function without being able to see the entire network.
      • NiallBunting 38 minutes ago
        Yeah, apps wouldn't be able to only listen to the firehose.

        There are some proposals for private files. However, I'm outside the AtProto world so not sure what exactly the suggested implementations are. I just hope they give enough control.

        I think the technology could potentially be used for way more than microblogging. I would love to use webapps that store the data on my devices and share it with specific people. The data and access under my control.

    Those of you old enough to remember etherpeg can now see an ATproto version:

    How common is it to host your own PDS? It's not really clear to me what the advantages/disadvantage are.

    This is really cool. It has retro vibes of the era when the Internet was still free from the big five domination.

    I could see this turning into a more modern and sane usenet replacement

    Blog post about this new site from February might shed some light: https://atproto.com/blog/new-site-2026
