Introduction
Tox is a peer-to-peer instant-messaging and video-calling protocol that offers end-to-end encryption.
Tox Protocol (Wikipedi) - https://en.wikipedia.org/wiki/Tox_%28protocol%29
The idea was to create an instant messaging application that ran without requiring the use of central servers. The system would be distributed, peer-to-peer, and end-to-end encrypted, with no way to disable any of the encryption features; at the same time, the application would be easily usable by the layperson with no practical knowledge of cryptography or distributed systems.

Tox relies on encrypted peer-to-peer networking to chat with others, eliminating the need for messages to travel through a central server. Skype itself used to be based on p2p networking, but since Microsoft acquired the company, Skype has been moving away from p2p towards centralized servers.
