What's a dht node? I saw some people talking about that but I didn't really understood what they were meaning.<|im_end|>

A distributed hash table (DHT) is a distributed system that provides a lookup service similar to a hash table. What differentiates a DHT from a normal hash table, however, is the fact that storage and lookup on DHT are distributed across multiple (can be millions) nodes or machines, and the node that gets to store a particular key is found by hashing that key, so in effect, your hash-table buckets are now independent nodes in a network.<|im_end|>

That was not helpful, at least wikipedia told me it was a Distributed Hash Table.<|im_end|>

Sorry for that! A DHT node is a participant in the Distributed Hash Table (DHT) network, responsible for storing and retrieving data from the DHT. Each DHT node has a unique identifier that is usually represented by a hash value. Nodes communicate with each other to share information about the data they are storing and to help locate data when requested by other nodes. In the context of peer-to-peer file sharing applications, DHT nodes are used to maintain a distributed database of peers participating in the network. When a user wants to download a file, they query the DHT network to find other peers that have the file available for download. DHT nodes are important components of many decentralised systems and are used in a variety of applications, including peer-to-peer file sharing, content delivery networks, and blockchain technology.<|im_end|>
