This project implements a peer-to-peer messaging system where users can register themselves with a central discovery server and communicate with each other directly. It consists of two main components:

1. Peer Implementation: This is the client-side implementation responsible for registering with the server, querying for active peers, sending and receiving messages, and maintaining a local SQLite database for message logging.

2. Discovery Server: This is the central server responsible for managing peer registrations, responding to queries about active peers, and removing inactive peers from the registry.

• Python 3.x

1. Run the Discovery Server: Start the discovery server by running python discovery_server.py.
2. Run the Peer Client: Start the peer client by running python peer_client.py.
3. Register: Enter a username to register with the discovery server.
4. Connect to a User: Choose to connect to another registered user by their username and start messaging.
5. List Active Users: View a list of active users currently registered with the discovery server.

• Python 3.x

1. Start the Server: Run python discovery_server.py to start the discovery server.
2. Inactivity Checker: The server automatically removes inactive peers from the registry after a set interval.

• Messages are logged locally in an SQLite database for each peer.
• Both the peer client and the discovery server should be running simultaneously for the system to function properly.
