## Demonstration

Want to see it in action?

   * Demonstration servers:
     * [peertube.cpy.re](http://peertube.cpy.re)
     * [peertube2.cpy.re](http://peertube2.cpy.re)
     * [peertube3.cpy.re](http://peertube3.cpy.re)
   * [Video](https://peertube.cpy.re/videos/watch/f78a97f8-a142-4ce1-a5bd-154bf9386504)
     to see what the "decentralization feature" looks like
   * [Video](https://peertube.cpy.re/videos/watch/da2b08d4-a242-4170-b32a-4ec8cbdca701) to see
   the communication between PeerTube and [Mastodon](https://github.com/tootsuite/mastodon)

## Why

We can't build a FOSS video streaming alternatives to YouTube, Dailymotion,
Vimeo... with a centralized software. One organization alone may not have
enough money to pay for bandwidth and video storage of its servers.

So we need to have a decentralized network of servers seeding videos (as
[Diaspora](https://github.com/diaspora/diaspora) for example).  But it's not
enough because one video could become famous and overload the server.  It's the
reason why we need to use a P2P protocol to limit the server load.  Thanks to
[WebTorrent](https://github.com/feross/webtorrent), we can make P2P (thus
BitTorrent) inside the web browser, as of today.

## Architecture

See [ARCHITECTURE.md](/ARCHITECTURE.md) for a more detailed explanation.

### Backend

  * The backend is a REST API.
  * Servers communicate with each others with [Activity
    Pub](https://www.w3.org/TR/activitypub/).
  * Each server has its own users who query it (search videos, query where the
    torrent URI of this specific video is...).
  * If a user uploads a video, the server seeds it and sends its followers some
    metadata (name, short description, torrent URI...).
  * A server is a tracker responsible for all the videos uploaded in it.
  * Even if nobody watches a video, it is seeded by the server (through
    [WebSeed protocol](http://www.bittorrent.org/beps/bep_0019.html)) where the
    video was uploaded.

Here are some simple schemes:
