Files are identified by applying a strong hash function to their contents, which gives a distinct "fingerprint" for each file. Bitzi calls the combination of standard hash functions used by its system "bitprints." A hash function (or hash algorithm) is a way of creating a small digital fingerprint from any kind of data. ...

Also provided are two types of Uniform Resource Identifiers (URI). First, the Magnet URI which uses the SHA1 hash identifier and is used by most Gnutella programs. Since version 0.6.0 the program Bitcollider also includes the KZHASH identifier used by Kazaa and Grokster. The Tiger tree hash, used by DC++ and Shareaza, is also included.

The second URI is the ed2k identifier which is used by eDonkey2000, eMule and OverNet. Bitcollider provides information since version 0.4.0.

Usage

Some peer-to-peer file sharing programs, such as LimeWire or Bearshare, offer an option to look up local files or network search results at the Bitzi website for more (or more trustworthy) information. A peer-to-peer (or P2P) computer network is a network that relies on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively few servers. ... LimeWire is a free and open source peer-to-peer file sharing client for the Gnutella network. ... BearShare is a popular Gnutella-based file sharing application created by Free Peers, Inc. ...

Often fake/misnamed files can be caught before downloading by doing a Bitzi lookup, as other users usually leave commented ratings. This ability also makes it invaluable for downloading large programs, movies etc which usually have many fake/substandard copies floating around in P2P networks.
