1. 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.

De flow means that all social resources can be aggregated and distributed with one click
in a system with many nodes, each node has a high degree of autonomy. Nodes can connect with each other freely 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 a nonlinear causal relationship through the network
This kind of open, flat and equal system phenomenon or structure is called decentralization 
extended materials:
compared with the previous Internet (WEB 1.0) era, today's Internet (Web 2.0) content is no longer proced by professional websites or specific groups, but by the participation of the whole Internet users and the creation of equal power levels. Anyone can express their views on the Internet or create original content to proce information together
with the diversification of network service shape, 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
3. Nakamoto is the first person to discover bitcoin. Bitcoin is not issued by any institution, and the total amount is only 21 million yuan. The transaction of bitcoin needs the consent of 6 people!
4. blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is essentially a decentralized database
for example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy something for you, you immediately record it and send it to you and all his friends, classmates, colleagues, as well as various groups and circles of friends, so that he can no longer resist. This is called blockchain
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
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.

Decentralized bookkeeping makes blockchain assets open, transparent and unable to cheat ~
the third feature of blockchain assets is decentralized bookkeeping
the transfer you give to others will not be delayed for several days because the bookkeeping institution is on holiday; Not because the bookkeeping institutions want to make profits, so they have to pay high fees; More will not be because of accounting institutions cheating, and suffer losses
because its bookkeeping is carried out by the whole network. The account book that you transfer to others will not be unified because of the loss of the account book data here or there, because the account book is jointly maintained by the whole network, and every node has a backup

the transfer you give to others will not be delayed for a few days because the bookkeeping agency is on holiday; Not because the bookkeeping institutions want to make profits, so they have to pay high fees; More will not be because of accounting institutions cheating, and suffer losses
because its bookkeeping is carried out by the whole network. The account book that you transfer to others will not be unified because of the loss of the account book data here or there, because the account book is jointly maintained by the whole network, and every node has a backup. If you transfer 0.5 coins to fire coin Niuniu, you two can look at the record data of the whole network together: whether it has arrived, several confirmed, etc., which is very transparent and fair.

7. Competitive bookkeeping is the bookkeeping method of bitcoin system. It solves the problem of how to ensure the consistency of bitcoin account book in decentralized bookkeeping system. There is no centralized bookkeeping organization in bitcoin system, and every node has bookkeeping right. How to ensure the consistency of bitcoin account book is an important problem
in the bitcoin network, the miners of the whole network participate in the competition of computing power. The miners with high computing power (also known as mining speed, that is, the ability of the computer to generate hash collisions per second) have stronger computing power and are easier to obtain the right to keep accounts. The miners who successfully seize the right to keep accounts are responsible for keeping accounts and synchronizing the account information to the whole network, In return, the miners will receive a new bitcoin reward generated by the system
for example, there is a gold mountain in front of us. The total amount of gold is 1000 tons, but there are a lot of sand and stones in it. When you are alone, it is easy for you to dig gold, but when more and more people are mining, the remaining gold will be less and less, and the mining cost will be higher. So at this time, we compare the mining speed, that is, the calculation power
as the price of bitcoin on the "currency exchange" rises, more and more people compete for the bookkeeping rights of bitcoin in order to obtain bitcoin, and the difficulty of computing power in the whole network increases exponentially.

8. How to apply blockchain in new retail
in view of the function of blockchain Traceability Technology, taking Jingdong as an example, this year, Jingdong took the lead in implementing blockchain Traceability Technology, and the effect is obvious
firstly, the supply chain of different participants in commodity circulation is connected with the blockchain storage system by using blockchain technology. It includes origin, procer, channel, retailer, brand and consumer. So that the information of each participant can be viewed in the blockchain system
secondly, the operators of blockchain alliance chain are roughly divided into the following items: Alliance chain, automation, visualization, data efficiency, cross chain bridging, each link has a complete set of operation mechanism, and the data chain information is comprehensive, automatic, open, efficient, reasonable and linkage
this operation and management mechanism is more scientific and reasonable. Especially in the food instry, taking beef as an example, consumers can clearly understand the authenticity of the purchased beef and the whole process traceability information through the unique traceability code of the purchased beef, which greatly improves their trust. At the same time, through big data public opinion to help enterprises carry out brand culture publicity and other intelligent marketing activities, to maximize the income of enterprises and consumers
finally, based on the obvious characteristics of retail instry, such as transaction data fragmentation, transaction node diversification and transaction network complexity, the collection, storage and integration of information such as commodity proction, circulation and delivery is the core proposition of end-to-end retail supply chain management
consumers, regulators and e-commerce stores are most concerned about the credibility, reliability, accessibility and security of the whole process information. The blockchain technology integrates many basic technologies such as consensus mechanism of multiple transaction entities, distributed data storage, point-to-point transmission and encryption algorithm, which is naturally suitable for end-to-end information management of retail supply chain. Protect consumers
previously, we mentioned the application of blockchain Traceability Technology, which can make the process clearer when consumers see the procts in that link. It provides a good platform for procer reproction, market supervision and e-commerce market operation and management. Let me give another example, which is bookkeeping
blockchain is essentially a "decentralized" huge ledger database. It can be said that the traditional centralized accounting method is transformed into distributed accounting. Blockchain is composed of a string of data generated by using cryptography correlation. In my opinion, the application of blockchain is intended to build a trusted distributed business ecological environment that can be self circulation and outward expansion
as I mentioned before, blockchain has the characteristics of transparency, openness and mutual knowledge. In this way, for the retail market, profit is divided into two parts, one is the real value of goods, and the other is the additional market information
two sources of profit should be considered reasonably. Based on the environment created by blockchain, market players can rece their vigilance and increase the possibility of cooperation based on the openness of information. This is the positive effect that I expected from the trustworthy distributed business environment. At the same time, it is also the basis and premise of distributed bookkeeping
in such a good ecological environment, cooperation can be more simple, efficient and low-cost, so as to realize the effective integration of resources and create more economic and social value. More importantly, I think that commerce is the result of the joint efforts of every market subject, and it is also a participant in the blockchain. Each participant can find his own position in the blockchain, contribute his own skills, and get corresponding rewards to realize his own value
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
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.
