The program enables peer-to-peer chat which doesn't require a centralized server relaying messages from peer to peer. It is implemented based on libp2p for network layers and written in Go. Basic ideas start from "Nobody wants his/her private messages get relayed and stored by untrustful third-party service providers even though they advertise the services' concrete security protocol". In other words, any kind of data transmitted between clients remain on their side, not on the side of middle men who could take off masks and reveal real face of 'Big Brother'.
