| ## Description | |
| This example showcases a minimal implementation of a **libp2p** node that can interact with IPFS. | |
| It utilizes the gossipsub protocol for pubsub messaging, the ping protocol for network connectivity testing, and the identify protocol for peer identification. | |
| The node can be used to communicate with other IPFS nodes that have gossipsub enabled. | |
| To establish a connection with other nodes, you can provide their multiaddresses as command-line arguments. | |
| On startup, the example will display a list of addresses that you can dial from a `go-ipfs` or `js-ipfs` node. | |
| ## Usage | |
| To run the example, follow these steps: | |
| 1. Build and run the example using Cargo: | |
| ```sh | |
| cargo run [ADDRESS_1] [ADDRESS_2] ... | |
| ``` | |
| Replace `[ADDRESS_1]`, `[ADDRESS_2]`, etc., with the multiaddresses of the nodes you want to connect to. | |
| You can provide multiple addresses as command-line arguments. | |
| **Note:** The multiaddress should be in the following format: `/ip4/127.0.0.1/tcp/4001/p2p/peer_id`. | |
| 2. Once the example is running, you can interact with the IPFS node using the following commands: | |
| - **Pubsub (Gossipsub):** You can use the gossipsub protocol to send and receive messages on the "chat" topic. | |
| To send a message, type it in the console and press Enter. | |
| The message will be broadcasted to other connected nodes using gossipsub. | |
| - **Ping:** You can ping other connected nodes to test network connectivity. | |
| The example will display the round-trip time (RTT) for successful pings or indicate if a timeout occurs. | |
| ## Conclusion | |
| This example provides a basic implementation of an IPFS node using **libp2p**. | |
| It demonstrates the usage of the gossipsub, ping, and identify protocols to enable communication with other IPFS nodes. | |
| By running this example and exploring its functionality, you can gain insights into how to build more advanced P2P applications using Rust. | |
| Feel free to experiment with different multiaddresses and explore the capabilities of **libp2p** in the context of IPFS. Happy coding! | |
