What is the logic of main.go?

The main function of the provided code is to initialize a Libp2p host, join a PubSub topic, and establish two goroutines: one to stream console input to the topic and another to print messages received from the topic.

First, the code initializes a Libp2p host using the libp2p.New function. Then, it creates a PubSub instance using the pubsub.NewGossipSub function and joins the specified topic using the Join method.

Next, the code starts two goroutines. The first goroutine, streamConsoleTo, reads input from the console using a bufio.NewReader and publishes it to the specified topic using the Publish method. The second goroutine, printMessagesFrom, subscribes to the topic using the Subscribe method and prints messages received from it.

In addition to the main function, the code also includes helper functions such as initDHT, discoverPeers, and streamConsoleTo that perform specific tasks related to DHT initialization, peer discovery, and console input streaming.

Overall, the logic of main.go is to create a Libp2p host, join a PubSub topic, and establish a communication channel between the console and the topic, allowing users to send messages to the topic and receive messages from it.
