Access restrictions specified in the lexicon

[byoda]

Hi,

I'm reviewing atproto and the BSky PDS to the BYODA pds I wrote and that is used for the BYO.Tube site. There is an uncanny number of similarities between the two in both architecture and implementation! One thing I haven't been able to find yet is whether you can specify access restrictions in a lexicon, for use cases like:

1. this post, comment or video should only be visible and accessible to people I have linked to in my social graph as 'friends'.
2. I want to grant a 3rd-party app access to this subset of data stored in my pds.

Did I miss this in the atproto spec or is it not supported?

Short answer is, this isn't supported. Right now ATProto is a fully public protocol and network: https://bsky.social/about/blog/5-19-2023-user-faq . There are off-protocol exceptions like chat, though, and they're planning to add E2EE messaging in the future.
