The Fediverse is a collection of decentralized digital, social spaces. Using protocols like ActivityPub allows various services to interact.

ActivityPub enables various services to interact and share data on behalf of accountholders. For instance, competing microblogging services can subscribe to accounts on other services. Also, one type of service can use another, such as a long form blog engine using an external microblogging service for comments. Or, a microblogging account can subscribe to accounts on different photo and video services.

ActivityPub is an official W3C recommended standard published. It provides client to server APIs and server to server APIs. The client to server APIs allow clients to work with different services. The server to server APIs allow services federate and to share data on behalf of their account holders.
