continuing to build up our permissioned data protocol! this one asks what a bucket actually is and where the data that constitutes a bucket is stored. it argues for maintaining the atproto ethos in the permissioned data protocol as always, looking forward to hearing your thoughts!

Permissioned Data Diary 2: Buckets - Daniel's Leaflets
The second in a series of posts building up a solution to permissioned data on atproto. We introduce buckets: a new protocol primitive for creating a shared social context.
Permissioned Data Diary 3: Your Bucket, My Data - Daniel's Leaflets
The third in a series of posts building up a solution to permissioned data on atproto. We look at two different models for where buckets live and why the simpler-looking one doesn’t work out.

AT Protocol is public by default. Everything you write goes into a signed, archived, and rebroadcastable repository that anyone can read from and moves throu…
Permissioned data is a love triangle - Nick's Blog
Permissioned data is a love triangle between the user, the identities they grant permissions to, and the applications everyone uses to view controlled data. We don't need to change or reinvent the protocol to have it, because ATProtocol already supports it.
Permissioned Data Diary 5: What’s in a Name? - Daniel's Leaflets
In this permissioned data diary, we dive deep into the URI structure for permissioned data on atproto and use it to motivate a bunch of the larger design.

The Atproto Spaces Alpha is Live - AT Protocol
Atproto Spaces, formerly known as “the permissioned data protocol,” is a new extension to atproto that enables non-public data. The alpha is now officially open. Here’s how to develop with it and what to expect as we work towards the full release.

new data diary! this is the most in the weeds yet, all revolving around our proposed URI structure for permissioned data. turns out you can figure out a lot about a protocol from the uri! as always, let me know what you think :)

Permissioned Data PDS Lexicons
discourse.atprotocol.communityhere it is folks! lots of details to still nail down, but this is roughly where our heads are at for the design of a permissioned data protocol give it a read and let me know your thoughts!
