libp2p Example

This is a simple Go application that demonstrates how to use the libp2p library to create a peer-to-peer network. The application initializes a libp2p host, sets up handlers for incoming streams, connects to a specified peer, and sends a message to that peer.

Features

• Peer Initialization: Create a new libp2p host that listens for incoming connections.
• Stream Handling: Handle incoming streams and print received messages.
• Peer Notification: Notify when peers connect or disconnect.
• Message Sending: Connect to a peer and send a message if an address is provided.

Prerequisites

• Go 1.18 or higher

Installation

• Clone the repository: git clone https://github.com/abuzaforfagun/p2p-network-basic.git
• cd p2p-network-basic
• go mod tidy

Usage

1. Build the application, go build -o libp2p-example (Windows: go build -o libp2p-example.exe)
2. Run the application, ./libp2p-example (Windows: ./libp2p-example.exe)
3. Copy the listening address (Ex. /ip4/127.0.0.1/tcp/53854/p2p/12D3KooWNjiwSApw2FfY3vVuLvtSFzvyAZHXHPasxqRm9tRLdS31)
4. Connect another Peer: ./libp2p-example <listening-address>
