"While it is called trackerless, in practice it makes every client a lightweight tracker. A clever protocol, based on a Kademlia distributed hash table or 'DHT', allows clients to efficiently store and retrieve contact information for peers in a torrent.I'm glad they simplified it.
When generating a torrent, you can choose to utilize the trackerless system or a traditional dedicated tracker. A dedicated tracker allows you to collect statistics about downloads and gives you a measure of control over the reliability of downloads. The trackerless system makes no guarantees to reliability but requires no resources of the publisher. The trackerless system is not consulted when downloading a traditionally tracked torrent."
All they have to do now is simplify the explanation!
