+particular, the IPFS Kademlia DHT uses a keyspace of length m=256, containing
 all bitstrings of 256 bits. The distance between any pair of keys is defined as
 the bitwise XOR of the two keys, resulting in a new key representing the
 distance between the two keys. This keyspace is used for indexing both nodes
