I am very excited about AT Protocol
AT Protocol (atproto) is the right mix of useful, practical, personal, and fun. I think it could save the internet.

Ok, a rundown of how we get p2p ATProtocol going: 1. Run *standard* ATProto services, locally 2. Use p2p to holepunch TCP connections 3. Add a thin layer for peering management Bundle all that up in an app, and we have a recipe for adding resilience & scaling to Bluesky. 🧵 teim:
FediForum Talk: Atproto: A Technical Introduction
By Daniel Holmgren, head of protocol at Bluesky PBC. AT Protocol (atproto) is the open protocol powering Bluesky and the emerging Atmosphere. This talk gives a high-level overview of atproto's app...
Introducing ATProto Science - Cosmik Labs
Announcing atproto.science! #ATproto has huge potential for supporting new ways of doing research, so we started @atproto.science to help bring together researchers, build community, and explore what's possible when science meets cutting-edge open social network protocols! 🧪 >
The AT Protocol | Bluesky
The AT Protocol (Authenticated Transfer Protocol, or atproto) is a standard for public conversation and an open-source framework for building social apps.

What is atproto?
What is atproto? atproto is two things: A protocol for creating open social networks An open social network atproto, the open social network Today the atproto network has 36+ million users and powers Bluesky and a handful of other apps. Almost all atproto data is public. Content like posts, likes, follows, and photos/videos are publicly accessible to any network participant in a permissionless way. As an example of how open the network is, here’s how easy it is to stream all public data on the network using a public atproto Relay like bsky.network:

the single most important part of atproto is the PDS as a user-controlled auth and storage layer to which clients can connect directly. death to appviews

So @iroh.computer is kinda magic. This turned out to be a huge project, and I'm still reducing the overall complexity, squashing bugs, and cleaning things up, but uh, the endpoint discovery works pretty seamlessly and I can view and download items from another users library in a pretty simple manner
I suspect we’ll see a bunch of apps that leverage atproto’s did:plc identity layer but store data out of band.

An ATProto-aware blob proxy! What a sensational idea. github.com/Blooym/porxie
GitHub - Blooym/porxie: [Mirror] A correct and efficient ATProto blob proxy for secure content delivery.

I'm now running a public instance of Porxie for anyone to use for within their application for evaluation purposes or as a replacement for Bluesky's CDN in the event of downtime or otherwise. 🦋 Bluesky CDN Compatible: porxie-bsky.dollware.net 🔗 General Purpose: porxie.dollware.net
