Survey Paper on Communication System Using Blockchain and Cryptography

Abstract

Abstract: Decentralized application make use of peer-to-peer networks, this ensures that no network failure can occur due to central node failure. Blockchain serves as a ledger which allows messaging to take place in a decentralized manner. Decentralized application for the communication and resource sharing is need in today’s world, where keeping data on a centralized server can be risky and a very expensive experience. With the help of some consensus, we can implement different ways to share resources and communicate. Together with Blockchain and Decentralized Applications, we can create a secure and very reliable messaging application that overcomes the drawbacks of traditional messaging applications.
