Early bits of #decentralization of #Badges look how, I created one in one instance (verifiedby.maho.dev) for 
@lqdev and it got decentralized/federated to other instance (badges.vocalcat.com)
So, badges are coming to the #fediverse.
In a technical note, I am using notes (so it gets published to mastodon), but adding the badge as "attachment" which is in the #activitypub spec. Tried document type before, but it does not render in Mastodon. I am going to work in supporting openbadges as activitypub attachments as well, so you can bring your existing openbadges to the fediverse.
