A distributed hash table (DHT) is a distributed system that provides a lookup service similar to a hash table: key–value pairs are stored in a DHT, and any participating node can efficiently retrieve the value associated with a given key. The main advantage of a DHT is that nodes can be added or removed … See more DHT research was originally motivated, in part, by peer-to-peer (P2P) systems such as Freenet, Gnutella, BitTorrent and Napster, which took advantage of resources distributed across the Internet to provide a single useful … See more DHTs characteristically emphasize the following properties: • Autonomy and decentralization: The nodes collectively form the system without any central … See more Because of the decentralization, fault tolerance, and scalability of DHTs, they are inherently more resilient against a hostile attacker than a centralized system.

In IPFS, the DHT is used as the fundamental component of the content routing system and acts like a cross between a catalog and a navigation system. It maps what the user is looking for to the peer that is storing the matching content.
