Mainline DHT

<p>Mainline DHT is the name given to the <a href="/facts/Kademlia/Mm6pGvqu">Kademlia</a>-based <a href="/facts/Distributed_hash_table/3eDfAaoh">distributed hash table</a> (DHT) used by <a href="/facts/Comparison_of_BitTorrent_clients/prxFGlHW">BitTorrent clients</a> to find peers via the <a href="/facts/BitTorrent/HP9ChWWW">BitTorrent</a> protocol. The idea of using a DHT for distributed tracking in BitTorrent was first implemented in Azureus 2.3.0.0 (now known as <a href="/facts/Vuze/4ScuT05P">Vuze</a>) in May 2005, from which it gained significant popularity. Unrelated but around the same time, <a href="/facts/BitTorrent%2c_Inc./gCLzcBUc">BitTorrent, Inc.</a> released a similar DHT into their <a href="/facts/BitTorrent_(software)/areLVdTL">client</a> called Mainline DHT, and thus popularized the use of distributed tracking in the BitTorrent protocol. Measurement showed that by 2013, the concurrent number of users of Mainline DHT is from 16 million to 28 million, with intra-day changes of at least 10 million.
