Fediverse

The Federation, or as often called the “Fediverse”, refers to a global social network composed of nodes that talk to each other. Each of them is an installation of software which supports one of the federated social web protocols. These social hubs create a decentralized and federated social network of millions of users all around the globe. This is how the internet was supposed to be.
