Patrick Dai, founder of Qtum, has shared his understanding of decentralization in a social media group on June 5th. He thinks network structure is evolving from C/S (client-server) model to CS/CS model, and every node of a network will become both a server and a client. When a network is filled with endless server nodes, it is thus decentralized.
Here is a translation of his share contents:
I have my own understanding of decentralization. My angle is on the transition of network structures. The internet is largely built on the structure of client-server model. Individuals send their request from client-end and server-end will receive and process instructions. This is a classic centralized structure and servers act as the center. If the center is attacked and crashed, whole system goes down.
Decentralized system in my mind is CS/CS model which means every node of a network is both a server and a client. In the old structure, your role is fixed. Server is always a server while client can only be a client.
Today, tech giants like Apple and Google, they are the major servers, we, as individual consumers and customers are among their pool of clients.
But situation is different in the case of cryptocurrency network, or more broadly, blockchain network.
For example, if I want to make a Bitcoin transaction, I can do it myself, or I can ask you help me do it. Either case, individual node perform the function of a server node. Everyone in a blockchain network has been endowed with two identities – server and client. And since everyone can perform as the server, there is no need for a center server anymore. A true decentralization is accomplished.
This is the core of all Cryptocurrencies and the fundamental for fairness of a blockchain network.
