This is an example of a decentralized key value store using libp2p and Kademlia.
It also uses mDNS to sync nodes on the same network, if the network allows it.
The node will attach to the port 30333.
When the node start you can use 2 commands: PUT and GET.
The key value store will be replicated between all nodes on the network.
