Is the digital currency exchange centralized

1. The core difference between centralization and decentralization is whether the private key is in the hands of the user. The decentralized platform can protect the user, such as celletf (celletf. IO), which solves the security problem of the user's assets, but the operation is relatively simple.

2. Decentralized exchange refers to the virtual currency exchange. Investors are expected to choose carefully. First of all, there is no formal virtual digital currency exchange or formal trading platform in China, so the state does not recognize virtual digital currency. If investors are involved, they may lose everything.

3. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis

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

Basic routine: the "trading market" of MLM digital currency is basically controlled by specific institutions. In order to attract investors' investment in the early stage, the currency price may be very high. Once the time is ripe, it will be sold intensively, and the price will plummet, and the investors will lose all their money

There are three characteristics of digital money MLM:

1. Digital money is a real proct, and it is highly packaged

2. The participants can get a head pulling reward, and the prize is the digital currency itself

3. Digital currency will appreciate with the increase of participants in the scam. In the cycle of digital currency appreciation, the number of participants who can obtain digital currency will also increase, and the participants, including the lowest level participants, will also gain, but in the cycle of devaluation, the bottom level participants often lose a lot

in 2017, the Internet Finance Association of Jiangsu Province issued the "internet pyramid selling identification guide", which named 26 so-called digital currencies as illegal pyramid selling projects covered or suspected to be covered with digital currency. They are: treasure money, Baichuan money, SMI, MBI, mark money, Diablo money, mmm, Fuda compound wealth management, carat money, V treasure, Vicat money, petroleum money, Huaqiang money, CB aiib Hong Kong Group, Yuansheng, Morgan money, beta money, WorldCom, u money, Jubao, 21st century fox, Wanxi wealth management, Wanfu money, Wuxing money, Yi money, Zhonghua money, etc

extended materials:

five ways to distinguish whether digital currency is pyramid selling currency:

1. Issuance mode

virtual currency does not rely on specific monetary institutions. It is proced by a large number of calculations according to specific algorithms, and is a decentralized issuance mode. Each different terminal node is responsible for maintaining the same account book, and the maintenance process is mainly to package and encrypt the transaction information by the algorithm, while the MLM currency is mainly issued by a certain organization, and the profit is made by pulling the head

2. Transaction mode

virtual currency is a kind of sporadic transaction spontaneously formed in the market, which is graally completed by a third party establishing an exchange after the scale is formed. The MLM currency is issued by an institution and traded on its own platform

3. Implementation method

virtual currency itself is an open source program, which is maintained in GitHub community. The parameters and methods of the total amount limit are shown in the open source code. The open source of MLM currency is completely ing other people's open source code, and there is no use of open source code to build programs, so its essence is controlled by the website like Q currency

4, whether to give the source code link

General decentralized digital currency will give the source code link in the prominent position of the official website, so as to show the operation mechanism of the monetary system openly and transparently. The MLM currency focuses on the transaction process of recharge purchase, but does not mention its operation mechanism. Even the website does not have the link address of the source code

5, whether the official website starts with HTTPS

generally, the addresses of the official website and trading website of decentralized digital currency start with HTTPS, and the purpose is that this kind of website can well protect the user's data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS

5. It should be reliable.

6. Although all websites and platforms related to digital currency trading and ICO projects have been blocked in China, the role played by exchanges in the field of digital currency is very important, so it has to be mentioned
Why do digital currencies need exchanges
as we all know, digital currency is based on blockchain technology and platform, and it is also one of the most typical applications of blockchain
taking bitcoin as an example, its platform provides the function of transferring money among users, but it does not provide the function of transaction and payment, which makes bitcoin unable to communicate with the outside world, let alone circulate, and thus cannot become a real currency
in order to solve this problem, the exchange was born
role of the exchange:
in addition to the above-mentioned trading and payment, the specific functions of the exchange are roughly asset management, matching trading and asset clearing, etc. To put it bluntly, it is equivalent to the Bank of digital currency. The matchmaking transaction here is actually to exchange for other currencies, such as bitcoin for Leyte. Of course, there are also some basic functions such as recharge and cash withdrawal. In principle, it is a centralized account book without being linked

on the other hand, the exchange also plays the role of stock exchange, making ICO (initial token issue) project possible
all kinds of token (token or token) can be raised and issued through the exchange
at this point, some people certainly think that the exchange is a combination of banking and securities trading
but not only that, the exchange also has the functions of futures and financial management, which means it also has the attributes of financial institutions such as futures exchange, securities companies and fund companies
it is not enough. In fact, the exchange also has the function of supervision, because there is no supervision. Therefore, the digital currency exchange can be regarded as a super financial center

the centralized exchange plays an important role, which obviously brings many security risks and trust crisis
all these are closely related to the violation of the "decentralization" advocated by blockchain
fortunately, some "decentralized" exchanges have emerged, which are based on the blockchain platform and rely on smart contracts to achieve the purpose of automation, de trust and transparency

let's briefly talk about how to build an exchange. Generally, a subject is registered first, such as the Singapore foundation, because the Singapore government encourages the development of blockchain, and high-quality project parties are registered in Singapore, which can be more recognized in the instry

the Singapore foundation can register by providing a company name and identity information of directors, and then it can do some legal compliance, which is also the advantage of the Singapore foundation. It can issue effective legal opinions to make the project compliance.

7. Let's briefly talk about my prediction of this thing:
1. The central bank's digital currency is definitely just a pure settlement network, which only allows banks and third-party financial institutions to use, and it is likely to stipulate that it must be used among institutions at that time. With this settlement network, the central bank should be able to review every transaction between institutions very easily
2. Don't expect it to be used by ordinary citizens. Freedom, equality and self responsibility are the basic concepts of digital currency. These are not allowed by the central bank
Freedom: the central bank will not allow you to transfer money as you want. The withdrawal of cash abroad should be limited to 100000. How can you complete the transfer by broadcasting data once
Equality: even if you hold on to the private key of reborn, it's hard for reborn to do anything to you. But the central bank needs to have life and death power over your property. So how can the central bank gain the authority to seize you in an open digital currency system? Use an admin level private key? Does it need multi-level permission control? Is it necessary to divide the internal and external network? After all these things are added, isn't that the traditional system? Why add to the cake and add to the blockchain
be responsible for yourself: it's easy to understand. If you lose your private key, it's all over. The reason why Yang Ma is called ma is that this kind of thing must be managed. Private key is too dangerous to be used by ordinary people

therefore, I think too much about what digital currency can fry or even replace bitcoin. It's something that has nothing to do with ordinary people.

8. Okex is a good platform with high security and the largest trading volume in the world. It supports multi currency leverage trading, legal currency trading and contract trading.

9. Because human greed and selfishness need a fair and trustworthy exchange. Conversely, why do you trust RMB
