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