    2222* Kademlia is less susceptible to eclipse attacks.
    2323  "For one thing, it is difficult to affect the routing tables of a Kademlia node, as each node tends to keep only highly available peers in its routing table. This increases the required costs for an attacker to convince honest nodes to link to the compromised nodes. Similarly, Kademlia uses iterative routing, exploring multiple nodes at each step, making routing less dependent on specific nodes and thus less vulnerable to attacks." [1] [[BR]]
    24 ** Kademlia lookups can be optimized by enlarging how many bits of IDs b, that are considered for each bucket. With b > 1 lookup steps would be decreased from O(log2 n) to O(log2^b^ n) but the number of buckets would be increased from to an expected 2^b^log2^b^. [2] [[BR]]
