What is Gnutella2?
Gnutella2 (G2) is a P2P network currently supported by Shareaza. Gnutella2 is Shareaza's premier P2P network, created and founded by Michael Stokes, aka Mike, the main developer of Shareaza until v2.0. It runs much like the original gnutella, with a similar connection system, but allows for powerful unicode searching capabilities with extensive metadata, TigerTree hashing, and generally fast connection speeds. The file distribution is unlike any other. For example, it was way ahead of gnutella in implementing Partial File Sharing (PFS), a system that allows users with partially downloaded files to share their parts of the file with other downloaders. It also has many features no other network has; Gnutella2 can tell you if the file has been reported as fake, low quality or otherwise unusable, it can tell you how stable or busy the host is, and it displays extensive metadata about a file, just by searching. Finding sources for files using eD2k or BitTorrent info hash (BTIH) can also be accomplished though the G2 network. These are just a few of the features of G2, which is a totally decentralized network, meaning it cannot be shut down, unlike eD2k or BitTorrent, for example.
