3 * A Bootstrap task for DHTs, use this only for nodes which do not announce
4 * themself to upper nodes as if they completed announcement they will attempt
5 * to bootstrap their DHT. This said condition currently only matches with
6 * bootstrap nodes (mode=boot) as they don't announce as they are already the
7 * bootstrapper and there are no super nodes.
9 * If there would be super nodes, a centralization occurs (on the super nodes).
