The center of block chain technology is evolving from cryptography to smart contracts and services.

In this article, we will examine how decentralization can be achieved through the use of block-chain technology in the field of communication services.

Satoshi Nakamoto explained the following in a bitcoin paper.

A purely peer-to-peer version of electronic cash would allow you to make payments online for a financial institution.

The decentralized communication in the same sense can be explained as follows.

A purely peer-to-peer version of communication service would allow peers to communicate directly for a telecommunication institution.

I think this should be the premise of decentralized communication.

Based on these assumptions, it is necessary to examine the structure and problems of existing services and to compare how decentralized communications differ in order to determine how existing communication services can be decentralized.

The major components of the existing communication service can be divided into a process of user registration, a process of identifying users, and a process of connecting identified users.

For example, in the case of a mobile service such as a cellular phone, a user uses his / her ID card to perform user registration and receive a telephone number. Then, the user can be identified through the telephone number, and if he / she wants to communicate with the other party, he / she presses the telephone number and connects with another user through the “Call” button. This is an old communication method that is old and user-friendly. To support this, telecom service providers around the world are building networks and providing services at a fee.

There is also Internet (IP) based communication service. For example, Skype, Hangouts, Facebook Messenger, and so on. These IP communication services register a user ID based on the user Account or e-mail. Then, the user can be connected by identifying the user based on the user ID, entering the partner ID in the software provided by the provider, or registering the friend.

Compared to existing technologies that have been used for a long time, decentralized communication should be differentiated. Therefore, it is necessary to grasp the limitations of existing communication services and see if decentralized communication can be a solution.
