There is no DHT (Distributed Hash Table) involved. The torrent file has
a list of SHA1 hashes covering the blocks making the file, so if you
retrieve the torrent file from a trustable source (the OpenIndiana web
site), your BT client can use the SHA1 hashes inside to check the
fragments it is downloading from all over Internet. You don't need to
trust other peers.
