How to download decentralization
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.
for your question, subtract the mean from each measurement.
"decentralization" is translated from the English word decentralization, which is composed of the prefix de -, stem central and suffix ization. Among them, the stem central means "center", the suffix - ization means "... Hua", and the prefix de - has the meanings of leaving, removing, canceling and opposite. Therefore, it is very accurate to translate it into decentralization
what is the meaning of decentralization
vitalik buterin, founder of Ethereum, published the article "the meaning of decentralization" in February 2017, elaborating the meaning of decentralization. He thinks that we should distinguish the centralization and decentralization of computer software from three perspectives: architecture, governance and logic
Architecture centralization refers to the number of nodes that the system can tolerate and continue to run; Governance centralization refers to how many indivials and organizations are needed to control the system; Logic centralization refers to whether the interface and data presented by the system are like a single whole
blockchain is a unified account book of the whole network, so it is logically centralized, which is beyond doubt. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized. The decentralization of architecture and governance brings three benefits to blockchain: fault tolerance, anti attack and anti collusion
five differences between blockchain and traditional distributed system
as a new kind of distributed system, blockchain is often mistakenly regarded as a distributed database or log system. In fact, there is a fundamental difference between blockchain and traditional distributed system, namely decentralization. Now let's look at the main differences between blockchain and traditional distributed systems:
(1) consistency algorithm: what blockchain needs to solve is the Byzantine general problem, that is, there are one or more fraulent nodes in the network, which may deliberately violate the protocol or transmit wrong data, Therefore, Byzantine fault-tolerant consensus algorithms, such as BFT, pow, POS, are often used in blockchain; The traditional distributed system only needs to consider the node failure and communication errors, and often uses consistency algorithms such as Paxos and raft, which can not resist the fraulent nodes
(2) central controller: there is no central controller in the blockchain network, and no node can control or coordinate the generation of ledger data. All nodes coordinate through consensus algorithm to generate consistent ledger. However, the traditional publishing system is often controlled by one organization, which uniformly dispatches all nodes to participate in the calculation
(3) rule making: the rule of blockchain is consensus protocol, also known as consensus mechanism, and consensus algorithm is a part of it. Consensus mechanism is generally designed and developed by a person or a team, and the corresponding proceres are developed for the community to use. This seems to be the same as the traditional distributed system, but the change and upgrading of the consensus mechanism of the blockchain requires the community to have a consensus on it. If no consensus can be reached, anyone can implement hard bifurcation and build another community and chain. This is the decentralization process of consensus mechanism.
above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized

there are a large number of user interfaces on coin an decentralized trading platform. Anyone can create an interface, and many people have already done so.
With the rapid development of human society, many people find that decentralization is a trend and also represents a new proction relationship. This is a new kind of proction relationship that is suitable for the business or business logic based on the highly developed and market-oriented human society and economy, equality and mutual trust. Since the decentralized trust mechanism blockchain has been established, many intermediaries will also face upgrading and innovation. For example, "Wall Street", a traditional medium which is essentially a financial intermediary, may soon develop into a new model
decentralization has changed more than one financial instry. In the consensus of China's excellent Internet company "Xunlei", science and technology is developing from centralization to decentralization. They are proud that their first P2SP download technology is a kind of decentralized technology. At that time, blockchain was not widely recognized. Xunlei believes that decentralized technology has many advantages. Its solution is light weight and low cost; It respects privacy and doesn't have an intermediate database to know everything; It accords with the development of society; It is a measure of environmental protection and sharing. In 2014, Xunlei made up its mind to do decentralized cloud computing, also known as shared computing, which is to distribute the computing needs to thousands of households and use the idle resources of users
such an attempt has got a very good market response, because the marginal cost of shared computing is lower than that of cloud computing, which can more effectively solve the social contradiction between the shortage of social computing resources and the high cost of computing, and rece the operating costs of enterprises, including Xiaomi, Aiqi and Xiongmao live broadcasting, which have become the customers of thunderbolt shared computing. In fact, the demand for computing in the current society is growing explosively. Whether it is artificial intelligence, big data, 4K, VR, the demand for network is higher and higher, the speed of computing is higher and higher, and the demand for speed is higher and higher. If you want to solve all the needs, you need to prepare sufficient computing resources. The player reward scheme is born to solve this problem
the significance of the player reward program is that in the shared computing ecosystem, Xunlei has joined the blockchain technology to share the bandwidth with the players through the cloud intelligent hardware Users of idle resources such as storage and computing power will issue the digital asset chain gram (original gamer coin) based on blockchain technology. Users participate in this plan for free, and they also voluntarily contribute idle computing resources to the society. Users actively contribute idle resources, Xunlei payment chain rewards users, Xunlei then packages and sells resources to enterprises, and a supply chain based on shared computing is completed. In this process, decentralized blockchain technology plays an important role
of course, complete decentralization lacks supervision, and there is a certain risk of being used. Therefore, the blockchain chosen by chaink is "alliance chain", not a completely decentralized public chain like bitcoin and Ethereum. Therefore, Xunlei still has the right of supervision. In order to rece and avoid the occurrence of malicious events of accounting nodes, and to ensure that users' transactions enter the block as soon as possible, Xunlei is more cautious in selecting accounting nodes. In the initial stage, Xunlei will choose its own servers with good network connectivity and stability, as well as its partners' servers with good network connectivity and stability, After the performance and security of the next generation of gamer cloud hardware are further improved, the gamer cloud node distributed in the user's family will be selected as the accounting node and constantly changed. At the same time, Xunlei united government actively cracked down on speculation, announced the firm no ICO, cracked down on third-party transactions, adopted the real name system, unlimited pre-sale activities and other means to resolutely curb the risk of speculation, so as to ensure the stability and sustainability of the player cloud and chain ecology
with the emergence of blockchain applications such as chaink, we can see that decentralized technology can make the instry no longer become so extreme, and all kinds of opportunities will burst out because of the introction of new mechanisms, which is of positive significance to the instry and the whole society
Decentralization means no center
extended meaning: 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 Piaget calls decentralization
This kind of open, flat and equal system phenomenon or structure is called decentralization 
extended data:
in a system with many nodes, each node has the characteristics of 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
