Blacksky As a Service: a First Look at Acorn - AT Protocol
Rishi Balakrishnan joins to talk about the work that went into building Acorn, Blacksky's new platform for creating moderated communities on atproto — and why the landing page never mentions a PDS.
Bluesky PDS | brad.quest
Bluesky is built on the open ATProto “atmosphere” network. The Personal Data Server is the network unit that serves as a repository for user data, identity, and media on the network.
Self-hosting - AT Protocol
Self-hosting a Bluesky PDS means running your own Personal Data Server that is capable of federating with the wider ATProto network.
Why (@why.bsky.team)

Overview
What is Blacksky? Blacksky Algorithms is building the future of self-governable online communities with tools that make complex infrastructure simple to deploy.

Every time you view or like a post or take most actions on Bluesky or Blacksky your requests go through your Personal Data Server (PDS). It’s also the home of all your data. To date, we’ve used other people’s software to run Blacksky’s fleet of PDS. In the next week we’ll be migrating to our own.
Blacksky was one of the 1st PDSs to allow open sign ups We are also now the largest PDS deployment that doesn't run any of bsky's code Sorry for the turbulence. It was the one-time price to pay for being able to build features like private accounts or sign-in via phone number w/o waiting on Bluesky
The blacksky.community web application now uses our own API servers to load posts, timelines and profiles. When data is missing (accounts on the edges of the network, outside of our primary community, etc) we leverage @microcosm.blue
