Fediverse is a portmanteau of "federation" and "universe". It is a common, informal name for a somewhat broad federation of social network servers whose main purpose is microblogging, the sharing of short, public messages. By running social network software that supports a standard set of protocols called ActivityPub, independently run servers can connect to the Fediverse,[1] allowing its users to follow and receive short messages from each other, regardless of which particular ActivityPub server implementation they are running. https://en.wikipedia.org/wiki/Fediverse See esp Mastodon.
