"PeerTube is an experimental decentralized federated video platform system that uses peer-to-peer technology to reduce load on individual servers. It's released as free software under the AGPLv3.0 licence. Started in 2015 by a single programmer, development of PeerTube is now supported by the French non-profit Framasoft. The aim is to provide an alternative to centralized platforms such as YouTube or Dailymotion." From PeerTube's Wikipedia page.
