The Fediverse ("Federated Universe") is a decentralized alternative to popular services like Twitter, Instagram, etc.
It uses the ActivityPub protocol, a W3C-standard.
Since Elon Musk has taken over Twitter, Mastodon and the Fediverse have seen a big surge in popularity.
I've compiled a few resources about the Fediverse and Mostodon, both in English and German:
