What is Distributed Hash Table (DHT)?

A distributed hash table (DHT) is a type of distributed database that is capable of storing and retrieving data associated with a network of peer nodes that can join and leave the network at any time. DHTs are typically designed to scale in a way that accommodates a large number of participating nodes that are organized in a structured and algorithm-dependent network topology. These network nodes coordinate amongst themselves to verify and store data in the DHT network without relying on a centralized coordinator.
