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"

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

extended data:

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

with the deepening of the interaction between subject and object, the constant 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. 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.

blockchain technology is one of the hottest technology concepts at present, which is popular in all fields, followed by a large number of technological innovation, application innovation, and a hundred schools of thought. FileNet is one of the typical technological innovations. It is a decentralized file network public chain, which is committed to solving the problem of decentralized storage and distribution. It is the first blockchain project in the world to put forward the concept of "distribution is mining", and is committed to building a valuable file network

FileNet is a sharing application technology in the Internet dividend free era.

in recent years, the Internet, once labeled as "free", is leaving! On the one hand, the Internet has made "free" popular, and it is difficult for users to pay for their own behavior; On the other hand, because of the increase in operating costs, websites that used to rely on free powder suction began to talk about paying users. But when people deeply realize the fun of "free" information sharing, it is difficult to charge users, which is the bottleneck of most network platforms

in order to solve this problem, FileNet puts forward a truly autonomous community concept, which adopts Dao mechanism. In the system of FileNet, users can upload and download without paying, and can get private cloud disk for free

FileNet is a super cloud system based on IPFs (interstellar file system) to provide content sharing, which is dedicated to storing and distributing valuable content. It is an IPFs incentive layer, which rewards miners to share their own storage resources and network resources in the mining situation. At the same time, FileNet is also a token, which runs on the distribution proof mechanism

4. Decentralization is a phenomenon or structure, which can only appear in a system with many users or nodes, and each user can connect and influence other nodes. Generally speaking, everyone is the center, and everyone can connect and influence other nodes. This flat, open-source and equal phenomenon or structure is called "decentralization"< Br > at the same time, "decentralization" is one of the typical features of blockchain, which uses distributed storage and computing power. The rights and obligations of the whole network nodes are the same, and the data in the system is jointly maintained by the whole network nodes, so that the blockchain no longer relies on the central processing node to realize the distributed storage, recording and updating of data. Each blockchain follows a unified rule, which is based on a cryptographic algorithm rather than a credit certificate, and the data update process needs to be approved by the user, so that the blockchain does not need the endorsement of intermediaries and trust institutions< The characteristics of br> de centralization:
centralization is first reflected in diversification. In the Internet world, there are no more than several portals has the final say. Various websites have begun to voice their own voice, express different choices and different hobbies, and these websites are distributed in every corner of the Internet world. Br > decentralisation is followed by the centralization of people, and decentralisation of content has become a trend, and people have become the key force to determine the survival of websites. It's a great change to build a website with indivials who lack interaction to gather talents and contribute their wisdom in the form of a circle. That is user-oriented, humanized< < br > decentralized content: < br > decentralization is the form of social relationship and content generation formed in the development of the Internet, which is a new network content proction process relative to "centralization"< Br > compared with the early Internet (Web1.0) era, today's Web (Web2.0) content is no longer proced by professional websites or specific groups of people, but is created by all Internet users with equal rights. Anyone can express their views or create original content on the Internet to proce information together< Br > with the diversification of network service forms, the decentralized network model is becoming clearer and more 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< After that, with the emergence of more simple and easy-to-use decentralized network services, the characteristics of Web2.0 became more and more obvious. For example, the birth of services more suitable for ordinary Internet users, such as twitter and Facebook, 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.

5. Hello, decentralized Web2.0, please log in or register

decentralized Web2.0 brings about a decentralized way of content consumption. The destruction of the sense of wholeness is not only a subversion of tradition, but also a greater obstacle to people's understanding of the real world. If Web2.0 stops here, it's just subverting another way of proction and consumption. Adding a zero to the already massive information world doesn't make us go any further in our understanding of the real world. That 2.0 can only be an unfinished 2.0 at most, Maybe what we need to do is try to reassemble the whole after the separation.

6. 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.

7. Data has been surging, and it's definitely an opportunity. IPFs and filecoin are so powerful, but another project, hurricane ecology, is also OK. It was built by the original storm video team. I think with the technical advantages of storm, the hurricane ecology will not be bad.

8. No, decentralized storage is storing digital money in a decentralized wallet. But this method requires users to be familiar with the operation of the wallet, and be able to remember the private key of the wallet skillfully. Bittok is easy to use, safe and stable, and has various functions

9. Hadoop can store massive data. It includes HDFS, a distributed file system, so it is feasible to store some of the files on node 1 and some on node 2.
when you need to store large files, HDFS will divide them into several small blocks (the size of the block can be determined by yourself) for distributed storage, and the name node will record the location of the storage, When an application requests calculation, it will move the calculation to the corresponding data. So, if you use Hadoop, you can believe it. Of course, you can also add some of your own security management moles or other middleware on it. After all, Hadoop is unsatisfactory and needs to be improved
at present, Facebook, Taobao, Yahoo! They have built their own data center with Hadoop to support massive data storage
