The addition makes Opera the first Web browser to natively support BitTorrent downloads, which normally require a separate, external client. Alongside the BitTorrent feature, Opera 8.02 will introduce a number of bug fixes including an update for Web pages using Flash.
BitTorrent has found immense popularity as a way to download files due to its distributed architecture, although its use thus far has largely been for sharing copyrighted content such as movies.
Operationally, a "seed" file, or one complete file, is all that is needed to initiate a BitTorrent download. Once initiated, seeds are downloaded by file sharers who obtain "bits" of the master file over peer-to-peer networks. The efficiency of distribution scales upward as more file sharers download.
