compared with the early Internet (WEB 1.0) era, Web 2.0 content is no longer proced by professional websites or specific groups, but the result of participation and creation by all Internet users with equal rights. Anyone can express their views on the Internet or create original content to proce information together
with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web 2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can co create or contribute content
with the emergence of more simple and easy-to-use decentralized network services, the characteristics of Web2.0 become more and more obvious. For example, the birth of services more suitable for ordinary Internet users, such as twitter and Facebook, makes it easier and more diversified to proce or contribute content to the Internet, thus enhancing the enthusiasm of Internet users to participate in the contribution and recing the threshold of procing content. Eventually, every netizen becomes a tiny and independent information provider, making the Internet more flat and content proction more diversified.
for your question, subtract the mean from each measurement.
From the perspective of Internet development, decentralization is the form of social relationship and content generation formed in the process of Internet development, and is a new network content proction process relative to "centralization"

from the perspective of astronomy, decentralization refers to the fact that the universe has no center, that is, a boundless mass without a central point
centralization is first reflected in diversification. In the Internet world, there are no more than several portals has the final say. Various websites have begun to voice their own voice, express different choices and different hobbies, and these websites are distributed in every corner of the Internet world. Br > decentralisation is followed by the centralization of people, and decentralisation of content has become a trend, and people have become the key force to determine the survival of websites. It's a great change to build a website with indivials who lack interaction to gather talents and contribute their wisdom in the form of a circle.

The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized

characteristics of blockchain Decentralization:
decentralization, not without the center, but by the node to freely choose the center, freely determine the center. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center
in a decentralized system, anyone is a node, and anyone can be a center. Any center is not permanent, but phased, and no center is mandatory for nodes
with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together

When it comes to blockchain, we often encounter the concept of "decentralization". So what is decentralization? Nakamoto has solved the difficult problem of "point-to-point e-cash" defined by himself. In this process, he "invented" the blockchain technology. Bitcoin system integrates technology and theory of cryptography, game theory and software engineering. Blockchain technology is an innovation formed by ingenious combination of existing technologies. Nakamoto didn't solve the problem of "peer-to-peer e-cash" out of thin air. He followed the footsteps of his predecessors, but he completed the last leap
"decentralization" is the competitive advantage of removing the centralized central node. It does not mean that there is no center, but the center node is a relatively neutral existence. These central nodes will not be mandatory. For a fully decentralized system, the connection between nodes is not completed by specific nodes, and all nodes can store and update data on the system, so as to achieve openness
decentralized blockchain is essentially a decentralized distributed ledger database. The simple understanding is that the data of blockchain is stored in many nodes of the network. The traditional way of data storage exists in one or several large nodes in the network. From this point of view, the so-called centralization and decentralization is the difference in the number of nodes storing data. Therefore, the decentralization of blockchain is relative. Data only exists on one node, which must be centralized. But if there are 100 nodes, they can be said to be decentralized relative to one node, but the degree of decentralization is not the same. At the same time, centralization and decentralization are not contradictory, and they are not completely opposite, because the word "de" in decentralization means the process of weakening and eliminating the center, rather than the concept that there is absolutely no center, which is completely opposite to non centralization
