1. Sharing from regional TV network: 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 & quot; Decentralization & quot;.
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.
3. 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

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
4. One of the characteristics of media theory is the wide ambiguity of various views. On the relationship between media and society, one of the focuses of the debate is the theoretical debate between "media centric" and "social centric", First, the view of "media center" lays particular stress on the field of media activities. It holds that the mass media, influenced by the irresistible driving force of the development of communication technology, has formed an independent force beyond the law of social movement. Mass communication has its own mode of operation and logic, highlighting the autonomy and influence of the media“ The view of "social center" regards the mass media as the reflection of political and economic forces, and holds that the media, just like its original intention, is only the carrier of information transmission. Therefore, the media theory is only a special application of the larger social theory. Second, the "media center" theory holds that the mass media has the ability to "acculturate" and "cultivate" the society, And regard the mass media as the main instigator of social change“ The theory of "social center" holds that media is always under the influence of social forces. It belongs to society and bears special responsibility for society. It is not difficult to see that the differences between theories are irreconcilable e to different footholds
5. Compared with the traditional centralized storage and centralized cloud services, the two complement each other and expand the market of data storage and computing, which will constitute the two cornerstones of the future digital economy. China has efficient, stable and cheap power and network infrastructure, which provides sufficient soil for the development of decentralized cloud computing. Taking IPFs as an example, 90% of the total network
computing power of IPFs is located in China. In the future, China will become the leader of IPFs. Taking xnmatrix as an example, it has become a global computing power leading decentralized cloud computing platform.
6. In fact, decentralization is equivalent to multi centralization. This is the characteristic of
blockchain technology. Everyone has the right to participate. Now blockchain projects are very popular. There is a SMIC blockchain service platform project initiated by Changsha high tech Zone, which is now in the formal operation stage. It has also been selected as a key project of Hunan blockchain. The next step is to recruit enterprises to join the chain.
7. Each node of the crowd node system has a high degree of autonomy, and the nodes are free to connect with each other. Any node can have a mandatory control function in stages. The nonlinear relationship between nodes can be expanded, flattened, and equal. The phenomenon or structure of the system is called by me The cognitive structure is broken and the physical self state is relieved
8. You press the mouse, do not move, let it brute force, and then click shoot
9. 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
