ActivityPub

About

ActivityPub (AP) is an internet federation protocol. It became the primary federation protocol for Mastodon starting with approximately version 2, which previously had been based on OStatus.

AP became a W3C recommendation on 2018-01-23, due in large part to the popularity of Mastodon.
