So how does BitTorrenting/torrenting actually work? Downloading a file by torrenting is an extensive yet well abstracted process, and in this video we dig in to the BitTorrent protocol itself (.torrent files, magnet URIs, trackers, BitTorrent peers w/ TCP and more, handshaking, choking algorithm, peer messages/spec, uTorrent Transport Protocol - uTP). This video approaches torrenting from a high level/language agnostic (AKA no specific programming language).

This video was made solely from information from numerous BEP's (BitTorrent Enhancement Proposals), open source projects, and other online sources of information. Sources are linked accordingly.
