Koorde: A Simple Degree-Optimal Distributed Hash Table
Koorde is a new distributed hash table (DHT) based on Chord 15 and the de Bruijn graphs 2. While inheriting the simplicity of Chord, Koorde meets various lower bounds, such as O(log n) hops per lookup request with only 2 neighbors per node (where n is the number of nodes in the DHT), and O(log n/log log n) hops per lookup request with O(log n) neighbors per node.
