The difference between centralization and decentralization

The difference between centralization and decentralization lies in efficiency, characteristics and cost.

Difference:

1, the efficiency is different: the efficiency of decentralization is higher than that of centralized network, but conversely, centralized network is safer. Generally speaking, centralized network is suitable for high security applications.

2. Different characteristics: Centralized network means that every two client computers communicate through the server. The distributed network needs to go through the server in the early stage, and the server is not needed in the late communication.

3. Different costs: Collective maintenance of the characteristics of blockchain can reduce many costs. Centralized network involves the maintenance, confidentiality and operation of many systems, which inevitably requires a lot of manpower, financial resources and material resources, and these do not exist at all for the decentralization of blockchain, so it can save a lot of costs.

These two concepts:

Centralization:

It is the central decision-making node. Nodes must rely on the center, without which they cannot survive. For example, we can only acquire knowledge by going to schools, such as primary schools, middle schools, universities and so on. Here, students are individuals, the school is the center, and everyone revolves around the school. This is centralization.

Decentralization:

Compared with the concept of "centralization", in the decentralized system network, every participant (node) is in an equal and free relationship, and no one depends on anyone. In a decentralized system, anyone is a node and anyone can be a center. Any center is not permanent, but phased, and any center is not mandatory for nodes.

Advantages of decentralization:

1, system security

In the past centralized network system, hackers could destroy the whole network by attacking a central node. However, in a decentralized blockchain network, there is no central node to attack.

2. Transaction security

Decentralized trading is convenient and simple, and there is no need for third party intervention, and there is no need to worry about information leakage.

3. Economy

Because decentralized processing is simpler and more convenient than traditional processing, it can save resources when trading a large amount of data at the same time.

4. Independent and efficient

Decentralized blockchain technology, without the intervention of a third party, can realize point-to-point interaction directly, which can realize high efficiency, no centralized agent and large-scale information interaction.
