1. Decentralization is a form of social relations and content proction formed in the development of the Internet. It is a new type of network content proction process relative to "centralization"
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.

2. According to Hou Jietai: the so-called centralization refers to subtracting the mean value of a variable from its expected value. For sample data, each observation value of a variable is subtracted from the sample average value of the variable, and the transformed variable is centralized
for your question, subtract the mean from each measurement.
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"
compared with the early Internet (WEB 1.0) era, today's Internet (Web 2.0) content is no longer proced by professional websites or specific groups of people, but is the result of the joint participation and equal power of all Internet users. Anyone can express their views or create original content on the Internet 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 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
since then, with the emergence of more simple and easy-to-use decentralized network services, the characteristics of Web2.0 have become more and more obvious. For example, the birth of services more suitable for ordinary Internet users, such as twitter and Facebook, has made 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
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
4. Hello, it's a great honor to be here to answer your question. The following are some of my views on this issue. If there are any mistakes, please point them out. Take the blockchain network mutual aid platform for example. The performance of decentralization in this platform is as follows:
open and transparent
open and transparent. Once all the information recorded on the blockchain is difficult to tamper with and cannot be hidden, users can check it at any time. Generally speaking, as long as the real name authentication is added to the plan, the blockchain will generate nodes, No one can modify (including the platform)
never downtime
the blockchain based on the public chain is not affected by any institution or indivial. As long as the incentive mechanism is effective and the Internet exists, the blockchain will exist. Generally speaking, since the platform service personnel are not available, the platform machine has been working
democratic decision-making
bottom up decision-making, blockchain proposes a variety of different consensus mechanisms to help users effectively form bottom-up decision-making and jointly participate in major decisions. Generally speaking, if the platform wants to modify a thing, for example, the content of the plan can only be carried out after more than half of the people participate in the voting, or the application for mutual aid needs mutual aid fund. When more than half of the people do not agree with the publicity, the platform will not pass. Thank you very much for your patience. If you have any help, please accept it. I wish you a happy life! thank you!

5. This is the second part of a series of articles on "key elements of becoming a better blockchain". Although decentralization is not an end in itself, it is a means to many ends, including resistance to censorship, corruption and collusion. Inclusive institutions with multi participation; And a fair distribution of wealth, power and influence. Decentralization is not suitable for most applications because of its low efficiency and high cost. However, for those applications that need decentralization, the underlying platform is much more reliable than the oral decentralized services. Did we go to the center? I want to remind us that decentralization is multidimensional, far from binary. Another closely related topic is unlicensed authorization, which will also be discussed here: allowing anyone anywhere to contribute to a project, platform or community is one of the most important parts of the spirit of decentralization
are there multiple client applications? There are two schools of thought. One assumption is that a single normative client application can concentrate limited resources on one project, and a development team can communicate more easily, which will maximize the success rate and competitiveness compared with other platforms. In addition, a single client application can prevent consensus failure caused by local account book inconsistency of different nodes (at least as long as each node upgrades its software after hard forking). On the other hand, the existence of multiple clients will make the network more likely to survive attacks (one client may stop block proction completely) or consensus failure (one or more clients cannot run the protocol correctly, which may lead to wrong block or stop block proction completely). In fact, both happened in Ethereum. But there are more subtle reasons. Firstly, the parallel application of multiple clients reces the dominant influence of a single core development team on the network, which is one of the biggest problems of bitcoin governance (zcash foundation will also decide to build a second zcash client to balance the power of electric coin). Moreover, different clients may make different architecture decisions and have different advantages (for example, mining, data search), and using different languages to write clients can enable more developers to participate in core development. Although parallel applications and beta applications are very good, the mainstream is the main network client: for example, bitcoin has at least 15 client applications, but 97% of the nodes run a program, that is, bitcoin core
how many organizations control mining computing power? The more parties involved in mining, the more difficult it is to collude with each other to engage in selfish mining, or to engage in double flower attacks (commonly known as 51% attacks, but the actual mathematical principles are more complex). This is not a hypothetical risk, as it has occurred in networks such as Ethereum classic and bitcoin gold. In addition, more miners means a fairer distribution of mining rewards. Although many indivial miners may participate in mining, because of incentives, they will gather in a few mines, and even a seemingly decentralized network may rely on a few entities for Mining: the three largest Ethereum mines jointly control 60% of the total power, while bitcoin's top four mines account for about 56%.

6. This problem has been discussed before. Today's automobile market needs an efficient and convenient environmental protection technology! Now there is just such a technology in the automobile aftermarket, which has been widely used. This proct is called shunshuang automobile oil drain valve. A special high-pressure vacuum pump is needed for the automobile oil drain valve to form a huge vortex and extract iron filings and oil sludge
with its disassembly free function, it can effectively rece the oil leakage and leakage caused by the sliding teeth of the oil pan screws, which is widely recognized by car owners! In the traditional way, it takes about 20 minutes for the oil to cool down and at least 8 minutes for the oil to drip naturally. And pumping treasure use special pumping equipment, 45 seconds can better complete the work, so as to save car maintenance time. High efficiency, energy saving and environmental protection. I feel that this project will have a good development.
