What is a #CID?
Itβs some kind of identifier that AT Protocol appears to use, but I canβt find a definitive resource on what it is or how itβs defined, and it appears to be related somehow to cryptocurrency (maybe?).
To make matters worse, there doesnβt appear to be any #PHP libraries that will parse or create CIDs.
Thereβs this one, but it doesnβt appear to support all CID codecs (not sure I understand that correctly)? https://github.com/danny50610/php-cid
@ramsey The only reference I can find to it in the documentation is here: https://atproto.com/guides/applications. Looks like it's a sha256 of content used to track whether something has been edited.
