Key–value pairs are stored in a DHT, and any participating node can efficiently retrieve the value associated with a given key.en.wikipedia.org/wiki/Distributed_hash_tableDistributed hash table From Wikipedia, the free encyclopedia Distributed hash tables (DHTs) are a class of decentralized distributed systems that provide a lookup service similar to a hash table: (key, value) pairs are stored in the DHT, and any participating node can efficiently retrieve the value associated with a given key.www.lamsade.dauphine.fr/~litwin/cours98/Doc-cour…

In computing, a hash table is a data structure that implements an associative array, also called a dictionary or simply map; an associative array is an abstract data type that maps keys to values. A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value can be found. During lookup, the key is hashed and the resultin…
