I think it&#39;s a good time to explain how we see @badgefed and @fediprofile, how they work together, and how #badges can use #ActivityPub and the #Fediverse. Also how this can help communities outside the fediverse! This is a quick overview of the architecture and ideas behind it. 🧵 1/ (thanks @johannab for the ask ...)

@badgefed is an open-source project that generates digital recognition in the form of #OpenBadges. OpenBadges is a specification based on JSON. BadgeFed currently uses version 2 of the spec. The main difference with v3 is verification. In OpenBadges v3, the badge can be verified by itself because the verification information is embedded in the credential. In OpenBadges v2, verification requires retrieving information from the issuer and badge endpoints. For our use case, issuing recognition on the internet, this is not a problem. In fact, we actually WANT that external verification step. It allows badges to reference issuer endpoints and remain connected to the systems that created them.

@mapache@hachyderm.io this is interesting, though I have one question before I get too much more interested: is there any genAI involved in these projects at all? :shiba_confused:

@mapache@hachyderm.io This is really interesting, thanks. I've been thinking about how #Moodle might use ActivityPub and OpenBadges seems like a really interesting use case
