A Human Resources Management System based on P2P network.

This system includes three different types of nodes: Central Node, Service Node, and Client Node.

Central Node is required for the P2P network to keep a list of active nodes.

Service Node will provide different services, such as user authentication, clock in and out, etc., to the P2P network. There may be one or more Service Nodes in the system that provide the same or different services.

Client Node is required for the user to interact with other Service Nodes and will provide a web interface using Flask, Bootstrap, and jQuery.
