What is Mastodon?

Mastodon is a type of server software that provides access to a decentralized open-source social network (some people also informally use the word Mastodon to refer to the actual network itself). This network is made up of countless privately operating servers or “instances”. Some are public for everyone to join, others have restrictions on signing up.

Vivaldi Social is one such instance and everyone with a Vivaldi account can join. Vivaldi Social is run on Vivaldi’s servers in Iceland and is administered by the Vivaldi team. You can post short posts, images, links and more, to share your thoughts and ideas with the world. It works similarly to most other social networks, such as Twitter or Facebook.

Users on Mastodon instances can follow and interact with users on their instance, but they can also follow and interact with users on many other instances. You can think of Mastodon instances like email service providers. With any email account you can potentially message anyone, it does not matter who provides the underlying services or if you are on the same service as your friend. This is also true on Mastodon and the Fediverse.

What is the Fediverse?

In the same context as Mastodon, you will often also hear the term “The Fediverse”. Mastodon is currently the most popular Fediverse server software. The Fediverse, or sometimes just Fedi, stands for Federated Universe. It’s a collection of many different, independent social media servers (others include GoToSocial, Pleroma, Friendica, and PixelFed), which can interact with each other. The servers can do that thanks to a common technical standard called ActivityPub.
