DHT

In order to coordinate, peers form a Distributed Hash Table: a distributed "dictionary" where each peer can store and get values. To initialize the first DHT node, run

from subnet import DHT, get_dht_time

dht = DHT(start=True)
# create the first DHT node that listens for incoming connections from localhost only

print("For incoming connections, use:", dht.get_visible_maddrs())

You can now start more peers that connect to an existing DHT node using its listen address:

dht2 = DHT(initial_peers=dht.get_visible_maddrs(), start=True)

Note that initial_peers contains the address of the first DHT node. This implies that the new node will share the key-value data with the first node, as well as any other nodes connected to it. When the two nodes are connected, subsequent peers can use any one of them (or both) as initial_peers to connect to the shared "dictionary".
