Auth-gated store for records that can’t live on public PDSes — private events, invite-only groups, members-only chat. Opt-in; zero cost if you don’t enable it.
Spaces as Layers - Nick's Blog
Public anchor records paired with sidecar records in permissioned spaces give ATProtocol apps a composable pattern for blending open discoverability with controlled access.
Proposal: OAuth-based account creation · bluesky-social atproto · Discussion #4587

Adversarial ATProto PDS Migration | Blog
An ATProto account lives on a Personal Data Server (PDS), and that service needs to be hosted somewhere by someone. There are a lot of options here, like a Raspberry Pi in your closet, a rented VPS in a datacentre, or a batteries-included service like bsky.social.

Playing with Parlances - Permissioned Data & AT Protocol - AT-WayFinding
Community privacy is one of our top priorities at @transrights.northsky.social which isn't possible out of the box with any ATproto implementation today that doesn't just hide an entire PDS. We're developing in the open and so I've published a proposal on it, feedback as always is we

Stepping outside the shapes series for a deep dive: how space configuration decides which people and which apps get credentials. Here be dragons.
The Arbiter - Group Management for Permissioned Spaces and Beyond - Zicklag's Leaflets
The permissioned data proposal has the concept of membership, but leaves it to the app to orchestrate it. The arbiter is our idea for a general-purpose, interoperable ATProto group membership service.
Permissioned Data Shapes: Self-Only Bookmarks - Nick's Blog
A self-only space is the smallest shape permissioned data can take: one authority, one member, one repo, and private bookmarks that share a record shape and a write path with public ones.

Overview | HappyView
Spaces are containers for permissioned data in atproto. Unlike regular public records that live in a user's repo, space records are gated by membership — only members can read or write data within a space.

At @roomy.space we've been cooking up the design for the next, ATProto-native iteration of Roomy, and that includes private data on protocol! The first component that we're working on is a group membership service that we're calling the "arbiter". Here's full overview of the design so far!
