Decentralized Application Analysis Center

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. The value of decentralization in jinwowo network analysis is as follows:
(1) fault tolerance: once there is a problem in the center, other nodes are easy to collapse. The centralized system is unlikely to be unexpected, because it depends on other nodes, and other nodes can not have problems together

(2) anti attack ability: decentralized system will make the cost of being attacked higher, because it lacks a sensitive central point, and the central point is more likely to be attacked by low cost. The reason is that we should all understand that the attack center may completely collapse, which is why more and more investors want the decentralized technology to become more mature

(3) anti Collusion: it is difficult for the participants in the decentralized system to sacrifice other participants and plot to make their own profits.

3. 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

4. Based on the first large-scale commercial application developed by gxchain, gongxinbao's decentralized data exchange provides enterprises with a completely different solution from the previous centralized data transaction (such as data middleman and data black market). The typical customers are network loans, automobile finance, consumer finance, Internet banking, Internet banking, Internet banking, Internet Banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking, Internet banking Banks and other enterprises, as well as government departments, insurance, medical, logistics and other government and enterprise departments with data exchange needs, have solved many core problems that have not been solved in the data security exchange and circulation of various instries with decentralized thinking. And can be used by the whole society, widely used in citizens' learning, work, life and other application scenarios, let the data release its e value, improve the efficiency of social cooperation.

5. Decentralizing is not to do without the center, but to let the nodes freely choose and decide 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. At present, many projects are being decentralized. GSN social bank is also decentralized. However, GSN reces the cost of credit investigation and enables unlimited use and sharing of trust data. GSN can greatly rece the false problem of massive data, so that data collection, processing and use can have better convenience. GSN expands the coverage of credit evaluation, expands the scale of the community, and uses distributed technology to collect data and information of user groups that can not be considered in the traditional mode through surveys. At the same time, GSN can carry out credit evaluation for special groups, that is, those who have no registered bank accounts but can contact with the Internet, so as to expand the scope of credit proct services. GSN reces the cost of credit proct management, so that credit evaluation, pricing, contracts can be automatically executed and managed without additional human participation, which greatly reces the cost of credit proct management, and greatly improves the scale of bank credit business processing. GSN improves the ability of credit to create value. Through the trust mechanism in the chain, the whole process of credit procts can have the ability of dynamic programming, which effectively expands the space of credit procts to create value.

6. It is an open source application that runs automatically, stores its data on the blockchain, motivates it in the form of password token, and operates with protocols that show valuable proof.

7. First, the goal of refined operation. For example, if your proct is just a tool, I'm afraid it can't be said that there are too many refined operations. Generally, it's enough to do a good job in routine user behavior analysis, and then cooperate with user qualitative research to guide proct design; If it is a content-based proct, or a proct with both function and content, it really needs to be considered. 2. Design statistical framework suppose that users will frequently interact and use functions on your app, and browse or generate content at the same time, so you need to design your statistical framework well while designing procts. 2、 Data collection first lists the data items you need, then evaluates which parts need to be reported by app and which parts can be counted in the background, and then adds them on the front and back platforms. Generally speaking, the collected data reported by app must be carefully checked and tested before release, because once the version is released and the data collection goes wrong, not only the previous efforts are wasted, but also a lot of dirty data will be brought. At the same time, the running efficiency of the client may be reced, and the gain is not worth the loss. 2. After data collation and data collection, all kinds of original data need to be processed into intuitive and visible data needed by proct managers. Here, we need to do some basic data logical association and display, so we won't repeat it. 3. Data analysis according to the statistical framework designed at the beginning, you can clearly see the data you need. Of course, the above is just a more basic analysis. If you get these data, you can analyze that users who use a function also like B function. The two are closely related. Can you consider more integration or interface adjustment in front-end design; For example, by analyzing the click stream, what are the paths for most users to visit or use the app, and do they hide the core functions too deeply? For another example, we can analyze different user attributes, such as male users and female users. Do they have significant differences in user behavior? wait. There is a big gap between the data analysis methods and models of different procts, which cannot be explained at once. So the above are more examples. 3、 Some principles need to be noted: 1. The data itself is objective, but the data interpreted must be subjective. The same data analyzed by different people is likely to draw completely opposite conclusions, so we must not analyze it with opinions in advance (for example, if we have hypotheses, we can use the data to demonstrate them); 2. Data collection by app must be of low priority. It can't affect proct performance and user experience because of data collection, and it can't collect user's privacy data (although many domestic apps don't do this); 3. Data is not omnipotent. You should trust your own judgment.

8. I feel that
de averaging is for the covariance behind the aspect. After de averaging, the mean value of each dimension is zero, and the mean value in the covariance is zero, which is convenient to solve
specifically, suppose that matrix A is decentralized to get B, then the covariance of B is the transpose of B * B

9. The operation of the game is mainly memory and graphics card powerful or not, desktop things change almost will not have any impact. Memory and graphics card for a computer is fixed, so as long as you regularly clean up the garbage to kill the virus is the best. Hope to adopt, thank you.
