BitTorrent (BT) is a communication protocol for peer-to-peer file sharing ("P2P") which is used to distribute data and electronic files over the Internet.

If you are interested in WebTorrent, I wrote a more detailed article.
WebTorrent に興味がある場合は、より詳細な記事にあります。

N.B WebTorrent is based on the WebRTC protocol. Safari does not support WebTorrent yet.
注意：WebTorrentはWebRTCプロトコルに基づいています。 Safari はまだWebTorrentをサポートしていません。

N.B It takes a few seconds to initialize WebTorrent.
注意 WebTorrentを初期化するには数秒かかります。
