SSB (Scuttlebutt) is a peer-to-peer network without any centralized server. All the stuff you write is registered on your local client and synchronized with your friends (peers) when they are reachable. Pub servers are used for regrouping peers but their are totally optionals. Read the doc for more information on the operation of the network. In this post, we will see how to deploy a public SSB server on Arch Linux.
