DHT is a protocol for searching nodes which distribute a torrent.
Torrent is a file with metadata which describes distributed content.

BTDigg's database is formed by DHT users.

torrent metadata (such as file names and file sizes) and a magnet link (torrent identifier).
This means BTDigg is the entirely legal system.

Decentralization of BTDigg provides the opportunity to search in the entire "torrent" space
inside and outside of trackers (except private trackers).
