Decentralized database
this paper mainly interprets an entrepreneur's transitional interpretation and amplification of the word "decentralization"
entrepreneurs or some people obsessed with Entrepreneurship often say that our procts are "decentralized" when they talk about procts in public
people are blind to things and the so-called unconsciousness, so what is "decentralization"? To understand "decentralization", we must first know what is "centralization"
1. The Internet is a new form of information transmission. Centralization is the centralized release of information, and participants often have no right to speak. The right to speak here is the right to speak at the level of guiding public opinion
2. Decentralization means that participants can have the right to speak, make voice and freely spread information
how is centralization formed
the lack of information resources leads to centralization. To some extent, the Internet user group is also the reason for the formation of centralization
how is decentralization formed
because the standardization of information resources leads to centralization, to a certain extent, the rise of Internet user groups has the conditions to build decentralization, and users' demand for information is expanding.
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 continuous balance of cognitive function and the continuous improvement of cognitive structure, indivials can be released from the egocentric state, which is called decentralization
The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is unified in the whole network, so it is logically centralized. 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
extended data:
characteristics of blockchain Decentralization:
decentralization, not without the center, but by the node to freely choose the center, freely determine 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
with the diversification of network service forms, 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

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
distinguish blockchain from ordinary database;, The main point is that the specific rules for putting data into the database are different. In other words, it can not conflict with other data already in the database. It is only added, immutable, and the data itself is locked to an owner (which can be owned). It is replicable and available. Finally, everyone agrees that the state of data in a decentralized database is compliant.
When it comes to blockchain, we often encounter the concept of "decentralization". So what is decentralization? Nakamoto has solved the difficult problem of "point-to-point e-cash" defined by himself. In this process, he "invented" the blockchain technology. Bitcoin system integrates technology and theory of cryptography, game theory and software engineering. Blockchain technology is an innovation formed by ingenious combination of existing technologies. Nakamoto didn't solve the problem of "peer-to-peer e-cash" out of thin air. He followed the footsteps of his predecessors, but he completed the last leap
"decentralization" is the competitive advantage of removing the centralized central node. It does not mean that there is no center, but the center node is a relatively neutral existence. These central nodes will not be mandatory. For a fully decentralized system, the connection between nodes is not completed by specific nodes, and all nodes can store and update data on the system, so as to achieve openness
decentralized blockchain is essentially a decentralized distributed ledger database. The simple understanding is that the data of blockchain is stored in many nodes of the network. The traditional way of data storage exists in one or several large nodes in the network. From this point of view, the so-called centralization and decentralization is the difference in the number of nodes storing data. Therefore, the decentralization of blockchain is relative. Data only exists on one node, which must be centralized. But if there are 100 nodes, they can be said to be decentralized relative to one node, but the degree of decentralization is not the same. At the same time, centralization and decentralization are not contradictory, and they are not completely opposite, because the word "de" in decentralization means the process of weakening and eliminating the center, rather than the concept that there is absolutely no center, which is completely opposite to non centralization
