Daily Term: Distributed Hash Table

Distributed Hash Table

A Distributed Hash Table (DHT) is a decentralized data structure that maps keys to values across multiple nodes in a distributed system, used for scalable lookups. For example, in peer-to-peer networks like BitTorrent, a DHT stores file metadata across nodes, allowing efficient retrieval without a central server. DHTs provide scalability and fault tolerance but require mechanisms like consistent hashing to balance load and handle node failures.
