This repo contains the Colonies P2P network stack based in libp2p.

Colonies uses it own DHT (Kademlia) implementation. Here is example code how to setup a DHT network constisting of two nodes.

dht1, err := dht.CreateDHT(4001, "dht1")
dht2, err := dht.CreateDHT(4002, "dht2")

Register dht2 with dht1.

err = dht2.RegisterNetworkWithAddr(c.Node.Addr, c.ID.String(), ctx)

When using libp2p, the adresses will look like this: /ip4/10.0.0.201/tcp/4001/p2p/12D3KooWMkeo4JoJkf2e5CQgkZy55EkD4gXR8M2oW9WtvMDBS17K

To publish key-value pair in the network, we must have a valid ECDSA private key.

crypto := crypto.CreateCrypto()
prvKey, err := crypto.GeneratePrivateKey()
id, err := crypto.GenerateID(prvKey)
