1. Centralized exchange and decentralized exchange have their own advantages and disadvantages, and the difference is very obvious. Let's take a look at the centralized exchange first. To put it bluntly, the trading mechanism of the centralized exchange is actually similar to our traditional stock trading
the first step is to register (open an account) and set the password. The second step is user authentication (KYC). The third step is to recharge. Here comes the key. The third step is the most important. Because you need to charge money to your address in the exchange before you can trade money in the exchange. The address of the exchange is actually a wallet address, but the ownership of the wallet is not the user, but the exchange, that is to say, the private key of the address, you don't have it!!! Do you understand the meaning
well, after recharging, the transaction is finished. The user submits the instruction (hanging order) to the server, and then the exchange will be responsible for matching the transaction, which is exactly the same as the stock. The last is cash withdrawal (withdrawal of currency). Users can send instructions to transfer the currency from the exchange address to their wallet address. The above is the trading mechanism of the centralized exchange. In these steps, all actions will have costs. No matter you recharge, trade or withdraw money, gas and handling charges can't escape
then let's look at the decentralized exchange. The trading mechanism is different from the centralized exchange. The first step is to register (open an account) and set the password. It doesn't make any difference. But then it's a little different. KYC is not used. But because there is a private key, the ownership of this address is completely controlled by the user. The second step is recharging. This is not very different from the centralized exchange. You still have to make your own gas
after recharging, we can also trade in the decentralized exchange. Users can also register orders, and exchanges will also be responsible for matching transactions, but the matching is done by smart contracts. Finally, cash withdrawal (withdrawal of currency) is initiated. After withdrawing currency, users can directly transfer the currency from the address of the exchange to their wallet address. This step is the same as that of the centralized exchange
the above is the trading mechanism of centralized and decentralized exchanges, and the difference between them is also obvious. Because all currencies in the central exchange are under its control, the trading efficiency is very high, and it is similar to the stock trading process, convenient and suitable for most users. Conversely, the risk lies in this. If the exchange itself loses its integrity or is attacked by hackers, the user's capital (currency) is not guaranteed
all the transaction processes of decentralized exchanges are completed by smart contracts, so the transaction efficiency is relatively low (TPS of blockchain technology has always been a soft rib), but relatively, the capital (currency) is completely in the hands of users, so the security is relatively high. In addition, there are also KYC, where KYC is needed for centralization, but not for decentralization, and the security of personal information is relatively high. Compared with the decentralized exchange, the advantages of the centralized exchange lie in the trading depth and the number of users, which are unmatched by the decentralized exchange
therefore, centralization and decentralization have their own advantages and disadvantages. It depends on the user's own choice. They like convenient, centralized, secure and decentralized.

therefore, centralization and decentralization have their own advantages and disadvantages. It depends on the user's own choice. They like convenient, centralized, secure and decentralized.
2. First of all, the decentralized exchange mainly carries out transaction matching, asset clearing and settlement on the chain. User assets are managed by smart contracts and controlled by users. The exchange does not touch user assets
secondly, the biggest value of the decentralized exchange is that users have absolute control over their own assets, and all transaction data and records will be linked through the blockchain smart contract, so as to ensure the openness and transparency of transactions and greatly rece the trust cost of users to the exchange
thirdly, it is very difficult for hackers to steal user assets unless they can get each user's private key. Even if the exchange's private key is leaked, the user's assets cannot be transferred without the user's private key, so it is very safe. With decentralized exchanges, you no longer have to worry about the risk of losing or stealing money
for this reason, with the graal maturity of the underlying technology of blockchain, decentralized exchange has great development potential, which is the trend in the future.

3. 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.
for your question, subtract the mean from each measurement.
4. What is "decentralization"
"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.

5. 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.

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

The core and essence of decentralization is actually the way of information dissemination and acquisition. Information (here refers to information in a broad sense, including all kinds of content that users can see, including news, goods, notices, announcements, etc.) is spread in two ways: centralization and socialization. The "decentralization" of wechat expected by Zhang Xiaolong is to spread (obtain) information through more social ways, spread through user relations in social networks, and allow users to spread or obtain information without centralized traffic entrance
< HR / >
in a word, decentralization is not separated from the platform, it does not rely on the platform diversion, it is only the acquaintance around you, it is called decentralization, the real decentralization is to rely on the social network, so that the information of businesses and commodities can be spread more widely, and more traffic sources can be obtained, not just the centralized platform diversion < br />
