kbuckets

K-buckets are a data structure used in distributed hash tables (DHTs) to efficiently manage and organize peer information in a peer-to-peer (P2P) network. The term "k-bucket" originates from the Kademlia protocol, which is one of the most well-known DHTs. Each k-bucket is a list that holds a limited number of contact information for other peers in the network.

The primary purpose of k-buckets is to maintain a balanced and efficient routing table. Each peer in

When a peer wants to find another peer, it uses the k-buckets to determine which peers are

K-buckets also play a crucial role in maintaining the network's resilience and fault tolerance. When a peer
