A distributed social network or federated social network is an Internet social networking service that is decentralized and distributed across distinct providers. It consists of multiple social websites, where users of each site communicate with users of the other sites. A social website participating in a distributed social network is interoperable with the other sites and is in a federation with them. Communication among the social websites is technically conducted over social networking protocols. Software used for distributed social networking is generally portablea[›] so it is easily adopted on various website platforms. Distributed social networks contrast with social network aggregation services, which are used to manage accounts and activities across multiple discrete social networks.
Open standards such as OAuth authorization, OpenID authentication, OStatus federation, XRD metadata discovery, the Portable Contacts protocol, the Wave Federation Protocol, the Extensible Messaging and Presence Protocol (XMPP) (aka Jabber), OpenSocial widget APIs, microformats like XFN and hCard, and Atom web feeds—increasingly referred to together as the Open Stack—are often cited as enabling technologies for distributed social networking.
A few social networking service providers have used the term more broadly to describe provider-specific services that are distributable across different websites, typically through added widgets or plug-ins. Through the add-ons, the social network functionality is implemented on users' websites.
The Electronic Frontier Foundation, a U.S. legal defense organization and advocacy group for civil liberties on the Internet, endorses the distributed social network model as one "that can plausibly return control and choice to the hands of the Internet user" and allow persons living under restrictive regimes to "conduct activism on social networking sites while also having a choice of services and providers that may be better equipped to protect their security and anonymity".
From a societal perspective, one may compare this concept to that of social media being a public utility.
