In other words, when sufficient video is buffered, there’s no need to deviate from the normal piece selection algorithm.&lt;p&gt;But the fact is that with the speed of today’s internet connections, the user is going to finish fully downloading the torrent in a fraction of the time it takes to view it, so they will still spend more time seeding than downloading.&lt;p&gt;In practice, the only time that the rarest-first algorithm is important is on poorly-seeded torrents, or in the first few hours of a torrent being published when the ratio of seeders to leechers is really bad. I plan to keep improving the piece selection algorithm so that WebTorrent can be a good citizen.&lt;p&gt;Also: you should note that not all WebTorrent users stream sequentially. That&amp;#x27;s just one option for downloading the data.&lt;p&gt;Also: It&amp;#x27;s noteworthy that BitTorrent Inc.&amp;#x27;s official torrent client (as well as the largest player by marketshare), uTorrent, offers sequential downloading, as well as selective file downloading. And the BitTorrent network remains very healthy.&lt;p&gt;&amp;gt; why they didn&amp;#x27;t take this opportunity to design a protocol that has more suitable trade-offs than BitTorrent&lt;p&gt;BitTorrent is the most successful, most widely-deployed P2P protocol in existence. It works &lt;i&gt;really&lt;/i&gt; well. My goal with WebTorrent was to bring BitTorrent to the web in a way that interoperates with the existing torrent network.&lt;p&gt;Re-inventing the protocol would have made WebTorrent fundamentally incompatible with existing clients and prevented adoption. The way we&amp;#x27;ve done it is better. The wire protocol is exactly the same, but there&amp;#x27;s now a new way to connect to peers: WebRTC, in addition to the existing TCP and uTP.&lt;p&gt;Also, re-inventing the protocol is a huge rabbit hole. There was already a lot of risk when I started the project -- will WebRTC get adopted by all the browser vendors? Will data channel stabilize and be performant? Is JavaScript fast enough to re-package MP4 videos on-the-fly for streaming playback with the MediaSource API? My thinking was: Why add inventing a new wire protocol and several algorithms to the table?&lt;p&gt;Thanks for your thoughtful comment. Hope you&amp;#x27;ll give WebTorrent and our new desktop app, WebTorrent Desktop a try!</text><parent_chain><item><author>jzelinskie</author><text>I work on some BitTorrent software and while it&amp;#x27;s a really cool protocol, it isn&amp;#x27;t designed to sequentially stream data.

Maybe one pause of a few seconds for a whole TV episode.&lt;p&gt;The problem is not the protocol but the lack of features like subtitles. And torrent contents not being standard. All this can be easily scripted to cover most cases.</text><parent_chain><item><author>jzelinskie</author><text>I work on some BitTorrent software and while it&amp;#x27;s a really cool protocol, it isn&amp;#x27;t designed to sequentially stream data.
