1. In a system with many nodes, each node has a high degree of autonomy. Nodes can connect freely to each other to form a new connection unit. Any node may become the stage center, but it does not have the mandatory central control function. The influence between nodes will form nonlinear causality through the network. This open, flat and equal system phenomenon or structure is called decentralization[ 2]
with the deepening of the interaction between subject and object, the continuous balance of cognitive function and the continuous improvement of cognitive structure, the indivial can be released from the egocentric state, which is called decentralization.

2. Centralized wallet, also known as off Chain Wallet, completely depends on the company and server running the wallet. bitcoin stored in the exchange is stored in the centralized wallet (off Chain Wallet). The private key is not owned by the user, but in the wallet project side of the centralized server hosting chain, the fund is usually entrusted to the server
private keys and assets are transferred to the wallet for centralized management. Users don't need to worry about the loss of the private key of this kind of wallet procts, resulting in the loss of funds; However, the capital risk will be more concentrated in the wallet project side and server side. When the centralized wallet is conquered by hackers, users will suffer unnecessary losses
decentralized wallets, commonly known as onchain wallets, have private keys maintained by users and assets stored in blockchains
decentralized wallets are often referred to as onchain wallets. The private key is handed over to the user. If the private key is lost, the wallet will not be able to help the user recover, and the funds will be lost forever. But the decentralized wallet is difficult to be attacked by hackers, and users don't have to worry about the self stealing of the wallet service provider
centralized wallets are where assets are stored, while decentralized wallets are where private keys are stored
except for the exchange, it is not recommended to use the centralized wallet, although losing the private key may help you find it. But there is always a risk that the company will run
a decentralized wallet is equivalent to a channel, a channel where you can master mnemonics to control your assets on the blockchain. For a decentralized wallet, the most important thing is to protect the security of the [private key]
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

3. Excerpt: yishop e-commerce system
at present, the best e-commerce in China is "centralized" mode. The so-called centralized mode means that an e-commerce platform concentrates all businesses and eyeballs / traffic and becomes the first entrance for consumers to shop. Consumers find goods through this entrance, and the platform allocates benefits through this entrance<
the concept of decentralization has been boiling in the past two years, and the climax appeared in December last year. Zhang Xiaolong elaborated the eight views of wechat public platform in detail, one of which is that "wechat wants to build a real decentralized system, it will not provide a centralized traffic entrance to all public platform parties and third parties".

4. Good morning. Why do you talk and decentralize every day? Yes, this strict one is good.

1. Efficiency is different: the efficiency of decentralized network is higher than that of centralized network, but conversely, the security of centralized network is higher. On the whole, centralized network is suitable for high security applications
2. Different characteristics: centralized network means that each time two client computers communicate with each other through the server. The decentralized network is the initial need to go through the server, later communication does not need the server
3. Different costs: the characteristics of collective maintenance of blockchain can rece a lot of costs. The centralized network involves the maintenance, confidentiality, operation and so on of many systems, which must require a lot of human, financial and material resources. These things do not exist for the decentralization of blockchain, so they can save a lot of costs

in the aspect of blockchain governance, an interesting trend recently is the re emergence of online virtual currency holder voting as a multi-purpose decision-making mechanism. Sometimes the vote of the coin holder is used to decide who runs the super node of the network (e.g. dpos in EOS, Neo, lisk and other systems), sometimes the protocol parameters are voted (e.g. the upper limit of Ethereum fuel supply), and sometimes the vote and direct application of approval (e.g. tezos) protocol upgrade are also concted
in all these cases, voting is automatic, and the protocol itself contains all the logic needed to change the verifier set or update its own rules, and automatically responds to the voting results
6. Empowerment is a term in positive psychology, which aims to give positive energy to others through the change of words and deeds, attitude and environment. Later, it was widely used in business and management. Its theoretical connotation is that enterprises release power from top to bottom, especially the power of employees to work independently, so as to drive the flattening of enterprise organization through the past centralized way, and maximize indivial intelligence and potential. And "drug empowerment" is to enable the digital construction of pharmaceutical enterprises, make pharmaceutical enterprises Internet, and promote the comprehensive reform of pharmaceutical online market

7. The following basic writing methods are provided to help you write the feeling after reading:
first, the concept of feeling after reading
the concept of feeling after reading has two meanings: one is true feeling after reading, which is not subject to any constraints; the other is a kind of writing style, which should be subject to various conditions ring the examination. The following is close to the first one. The main purpose of writing this feeling after reading is to show it to yourself. It must be true and write what you feel (of course, the feeling should be meaningful and worth writing). It is different from the experience notes. It should be unfolded to write, as much as possible like an article, and try to write vividly, realistically and profoundly. Generally, we should write clearly what we have read, what we feel, what we associate with, and what effect we have on ourselves. It doesn't pursue style and format. It can be long or short
Second, the writing method of the feeling after reading
the most important point of writing the feeling after reading is to read the "eyes" of the books or articles you read. It is the basis, center and starting point for you to write. We have already talked about this problem in the previous lecture, but we will not talk about it here. Secondly, there are certain rules for writing the feeling after reading. In some books, it is summed up as "quoting, discussing, linking and combining", which is the same as the formula. We can't ignore these rules. As long as the content of the exam is creative, it's OK to apply this formula; However, we should not be limited by it. We can write stereotyped "eight part essay". We can also try to have our own creativity and personality in structure. But in any case, the feeling after reading is inseparable from "reading" -- the quotation, summary, evaluation of the original text, etc., is inseparable from "feeling" -- one's own feelings. As long as the two words are well expressed, it is a good feeling after reading< After reading an article or a book, write down the feeling, experience, ecation and enlightenment, and the article is called "after reading"< The basic ideas are as follows:
(1) briefly describe the relevant contents of the original text. For example, the title of the book, the author, the writing time, and the content summary of the original book or the original text. The purpose of writing this part is to explain where the feelings come from and to pave the way for the following discussion. In this part, we must highlight a word "Jian". We must not narrate the specific content of the book or article in large sections. Instead, we should briefly describe the parts that are directly related to our feelings and omit the things that have nothing to do with our feelings< (2) clarify the basic point of view. Choose the point you feel most deeply and express it clearly in a simple sentence. Such sentences can be called "opinion sentences". This opinion sentence expresses the central point of this article“ The position of "opinion sentence" in a text can be flexible, either at the beginning of the text or at the end or in the middle of the text. For beginners of writing, it's better to take a straight to the point approach and put your point of view at the beginning of the article
(3) putting facts and reasoning around the basic point of view. This part is the original part of argumentation, which is the elaboration of the basic point of view (that is, the central point of view). It proves the correctness of the point of view by putting facts and reasoning, so as to make the argument more prominent and more convincing. In this process, we should pay attention to the fact that the facts and reasoning must be closely around the basic point of view and serve for the basic point of view
(4) integrate basic ideas with practice. A good review should have the flavor of the times and true feelings. To achieve this, we must be good at integrating with practice. This "reality" can be an indivial's thought, words and deeds, experience, or a social phenomenon. When connecting with practice, we should also pay attention to closely surrounding the basic point of view and serving for the point of view, instead of blindly connecting and disjointed
the above four points are the basic ideas for writing the feeling after reading, but they are not immutable and should be flexible. For example, "brief introction of the original text" is generally before "clear point of view", but the order of the two is also interchangeable. Furthermore, if the facts presented in the third step are social phenomena or personal experiences, there is no need to write the fourth part.
