The Peer-to-Peer Messaging in an app that does not rely on a central server to intermediate the messages across the peers. The app is intended to provide privacy, high communication efficiency, censorship resistance, and extra resilience to the users. Also, the app intends to provide users with peer-to-peer communication independent of network connectivity. This can be extremely useful in disaster-prone and remote areas (or even in case of a network outage) where network connectivity might not be a go-to thing. Hence, the app would be reliable and secure at the same time which is the main motivation to develop this application.

A Native module for Google's Nearby Connection API has been developed in this application so that it can be used in react-native. The methods that are exposed are:
startDiscovery - Starts discovering nearby devices - Takes id: string as an input parameter which is the identifier for the device
startAdvertising - Start Advertising to nearby devices - Takes id: string as an input parameter which is the identifier for the device
sendMessage - Sends message to nearby devices - Takes id: string and payload: string as the input parameter. The id is the identifier of the nearby device
receiveMessage - Receives message from nearby devices
getEndpoints - Get Nearby devices available
