The middle computer is acting as a “seed” to provide a file to the other computers which act as peers. This ensures that any modification of the piece can be reliably detected, and thus prevents both accidental and malicious modifications of any of the pieces received at other nodes. If a node starts with an authentic copy of the torrent descriptor, it can verify the authenticity of the entire file it receives.

Once a peer has downloaded a file completely, it becomes an additional seed. As more peers join the swarm, the likelihood of a completely successful download by any particular node increases. Relative to traditional Internet distribution schemes, this permits a significant reduction in the original distributor’s hardware and bandwidth resource costs. A peer is any computer running an instance of a client.

Peers that want to download the file must first obtain a torrent file for it and connect to the specified tracker, which tells them from which other peers to download the pieces of the file. However, this protection, theoretically, comes at a cost: downloads can take time to rise to full speed because it may take time for enough peer connections to be established, and it may take time for a node to receive sufficient data to become an effective uploader. The peer distributing a data file treats the file as a number of identically sized pieces, usually with byte sizes of a power of 2, and typically between 32 kB and 16 MB each. Pieces with sizes greater than 512 kB will reduce the size of a torrent file for a very large payload, but is claimed to reduce the efficiency of the protocol.

When another peer later receives a particular piece, the hash of the piece is compared to the recorded hash to test that the piece is error-free. Peers that provide a complete file are called seeders, and the peer providing the initial copy is called the initial seeder. Torrent files are typically published on websites or elsewhere, and registered with at least one tracker. The tracker maintains lists of the clients currently participating in the torrent. The flag is intentionally placed in the info section of the torrent so that it cannot be disabled or removed without changing the identity of the torrent. The purpose of the flag is to prevent torrents from being shared with clients that do not have access to the tracker.

The flag was requested for inclusion in the official specification in August 2008, but has not been accepted yet. Clients that have ignored the private flag were banned by many trackers, discouraging the practice. The client connects to those peers to obtain the various pieces. If the swarm contains only the initial seeder, the client connects directly to it and begins to request pieces. The effectiveness of this data exchange depends largely on the policies that clients use to determine to whom to send data. But strict policies often result in suboptimal situations, such as when newly joined peers are unable to receive any data because they don’t have any pieces yet to trade themselves or when two peers with a good connection between them do not exchange data simply because neither of them takes the initiative.

Peers arriving after the initial rush might find the content unavailable and need to wait for the arrival of a “seed” in order to complete their downloads. A strategy adopted by many publishers which significantly increases availability of unpopular content consists of bundling multiple files in a single swarm. This may expose users with insecure systems to attacks. However, with i2p, torrents can only be downloaded from within the i2p network.

This can be useful for users trying to avoid copyright complaints from their ISPs, maintaining privacy, or avoiding censorship. Private trackers offer users a greater degree of privacy, compared to public trackers, but have the downside of a single centralized point of failure. If the user adds a torrent from i2p, it will be seeded on both i2p and the clearnet, and if a user adds a torrent from the clearnet, it will be seeded on both the clearnet and i2p. For this reason, torrents previously published only on i2p are made available to the entire Internet, and users of i2p can download any torrent on the Internet while maintaining the anonymity of i2p. Hollywood studios for distributing popular content from their websites. March 2008 experimented with bittorrent distribution, available online.

Only selected works in which NRK owns all royalties are published. Responses have been very positive, and NRK is planning to offer more content. 3 million existing files, and all newly uploaded files, in August 2012. This method is the fastest means of downloading media from the Archive. This is a known cause of some home routers ceasing to work correctly.
