『一』Blockchain digital currency exchange platform construction solution

Digital cash exchanges are the focus of competition in the financial field. With a good digital currency exchange, It has a great advantage in peer competition. The market of digital cash exchanges is a global market, and it is involved in global trading business hosting platforms. Digital cash exchanges have different customization needs and different functions due to different data. A good digital cash exchange platform has rich functions, safe and powerful performance, and is differentiated among similar products. Blockchain digital asset exchange technology development

The unique interface of digital cash exchanges can provide convenience to customers Fund transfer methods, such as fast recharge, currency withdrawal, currency recharge, etc. It can also support multiple transaction methods, currency transactions, legal currency transactions, over-the-counter transactions, etc.

1. Off-site transactions So: Off-site exchanges are also called OTC trading markets. This is a place with no fixed place, no fixed rules and regulations, and no prescribed trading products. Users can achieve two-way transactions on off-site exchanges. The transactions are very free, just like other blockchain applications. There is no unified trading system and mechanism for off-site exchanges

2. Currency transaction: Currency transaction, as the name suggests, is a transaction between digital currency and digital currency. Currency is used as the evaluation unit to purchase other currencies. Price priority and time priority are used for intermediation.

3. French currency trading: French currency trading can be said to be the most direct way. What is the target price of the digital cash platform? The direct purchase transaction by users with fiat currency is a French currency exchange. The disadvantage of French currency exchange is that the currencies that can be purchased are limited. For encrypted currency types, it is necessary to purchase other types of currencies and exchange them through currency transactions.

Since the digital asset exchange is targeting the global market, its language richness is very important. The digital asset exchange not only supports the development of multiple currencies, but also supports the customized development of multiple functional modules, and also supports the development of languages ​​in various countries.

The functions of the blockchain digital asset exchange will not stop here. With the upgrade of technology in the future, new and better functions will also appear. Similarly, functional requirements also promote technology upgrades.

『二』 Alpha proposed that blockchain should solve the problem of "exchange dependence"

Alpha, executive director of the FBDEC Blockchain Developer Foundation, pointed out:

"Digital Currency must solve the problem of exchange dependence

Digital currency transactions based on peer-to-peer rely too much on exchanges to realize their value. Without exchanges, they are just a lot of worthless numbers and distributions. It can only rely on exchange gambling to realize its value. In this case, Coin has no other value support at all. It is just a value network formed by multiple parties in the transaction "betting on a future currency price increase."

Alpha calls this phenomenon:

Exchange dependence problem

(The first proposer in the world is: Alpha)

1 .When exchange gambler transactions increase, the currency price rises.

2. When trading gamblers trade less, the currency price will fall.

3. The currency price rises indefinitely while the fiat currency remains unchanged.

4. Payment for physical products and wealth gained from mining: rely on exchanges to realize value.

5. Cutting leeks to attack, repeated.

There are two ways to get rid of dependence on exchanges: (This article only explains the first one, and the second one is a commercial secret)

The first one: in the block Chain consensus layer, incentive layer, application layer development:

Blockchain B2B, B2C, O2O, blockchain mall allows everyone to "free upload" and "offline products", "choose "Coins you accept" and "push to social networks"

This kind of free blockchain mall can lock Coins in the distributed blockchain network through "multi-node voting". Both parties to the transaction can jointly designate multiple referee nodes.

If the seller delivers the goods, information is sent to the entire network

If the buyer receives the goods, the referee node must make a judgment.

If the transaction is completed, the referee node will obtain a part of the Coin

This process is a bit like Alipay, the only difference is:

Alipay can use funds Accounting uses the funds being traded, which will pose another risk to buyers and sellers (if Alipay goes bankrupt, the transaction system will collapse)

The blockchain network "freezes funds" through a distributed network< br />
Then each time the "referee node votes" are designated, "mining" is formed during the voting process to build a more powerful and secure transaction network. (This is a transaction network that cannot be closed, and everyone will conduct transactions based on consensus. No one can divert funds to do other things before the transaction is completed.)

Even more clever is:< br />
While the blockchain mall can freely upload products, people can also trade through "digital exchanges"ot; Use the day's trading price formed to evaluate your own products. Choose any Coin you accept (no matter who issued it, as long as it accepts the consensus)

If you issue a new Coin and most people reach a consensus and accept payment, it is also feasible.

The development of blockchain needs to get rid of "exchange dependence". This is also the application that I will develop and contribute to the world for free. Provide the world with more powerful tools to promote the "development, education, and application" of blockchain.

In the next time, Alpha will develop this blockchain mall and contribute it to everyone. We look forward to cooperating with everyone.

『三』What is an exchange and what is its role?

What is an exchange and what is its role?
1. What is an exchange? An information platform for trading certain information and items, etc. requires a fixed location called an exchange. The exchange, with the help of the information platform, realizes the sharing of property rights information, off-site transactions, unified coordination, and balances the property rights trading market and various terms.
2. What should you pay attention to when developing an exchange? 1. Choose a safe and reliable company that meets your needs. 2. Open a company and set up a company bank account 3. Apply for or assist in digital asset exchange licenses in operating areas as much as possible.
3. What is the use of blockchain exchanges? Building exchanges can meet the public’s need to make money, and is safe and stable. Blockchain exchanges are different from general trading platforms. Blockchain exchanges have the characteristics of distributed accounting, openness, and non-tampering and deletion. Suppose you keep accounts together, since everyone has written them down, but do they dare to change them? The answer is no, why don’t you dare to change it? Because it is very difficult and risky, unless everyone reaches an agreement and conspires to change the ledger, it will be too difficult. Why everyone keeps accounts at the same time? Because it ensures fairness, openness and disintermediation. The same is true for blockchain. Once the data is imported and the currency is listed on the exchange, it is very difficult and almost impossible to modify it.
4. How exchanges make money 1. Handling fees, this is the basic profit point. Usually both parties to the transaction need to pay a certain proportion of handling fees to the platform during the entire matching transaction process. At present, the main ratio is about one thousandth to five thousandths. '2. Coin listing fees. The role of investment banks is to provide currency issuance and underwriting services for digital currencies. The main method is for investors to use cash to conduct over-the-counter transactions to purchase "fiat currencies" (referring to circulating virtual currencies recognized by exchanges), and then Use fiat currency to purchase tokens of the issued currency. 3. Market makers. Compared with traditional stock exchanges, digital currency exchanges not only match transactions, but also play the role of market makers. The role of the market maker is to increase the liquidity of the market and thereby earn the price difference.
Sha Seng Technology is motivated to develop blockchain technology.Manager Wang: (15/5) *9043/II31. We have successfully mastered blockchain digital asset-related technologies for 11 years. We have been at the forefront of blockchain technology for many years. Currently, we have developed many blockchain systems: Blockchain wallet, public chain, alliance chain, private chain, exchanges: OTC transactions, C2C transactions, currency transactions, etc., quantitative contracts, blockchain IM, blockchain asset interest generation, blockchain BAAS platform, blockchain Anti-counterfeiting traceability, blockchain payment, blockchain practical application implementation projects. On the road of blockchain, we have left too many technical footprints. If you want to know more about Sha Seng Technology, please come and cooperate. Build a digital currency exchange, a virtual currency trading platform, and a virtual currency payment system.

『四』The difference between listing on the public chain and listing on the exchange

The difference between listing on the public chain and listing on the exchange is as follows:
Going on the exchange: As we all know, in the blockchain In the digital asset trading ecosystem, digital currency exchanges are a very important existence because they are the bridge between project parties and investors. However, in this capital-driven market, as a new thing, the financial sector has not fully accepted it. Although many countries have slowly made changes in their policies, as a thing that challenges the national sovereign currency, many countries are not interested in digital. Currency remains cautious. Therefore, in such an environment that lacks supervision, blockchain and digital currency exchanges are now overwhelming, and there are a lot of random ideas.
In this case, as a digital currency no matter how it is issued, as long as you have a certain amount of traffic and a certain strength, you can generally easily access second- and third-rate exchanges. When encountering mainstream exchanges with slightly stricter audits, in addition to having a digital token system and traffic, find an influential website to endorse it, and then write a "high-end" white paper, which can also be mainstreamed. Exchange. So this is why any currency can be listed on the exchange.
Going to the public network: Once a blockchain is online on the public network, it means that a real blockchain is officially born.
The ERC-20-based token has completed its original mission and needs to be destroyed. The project party will generally convert the original token into the main network currency (Coin) at a ratio of 1:1 after the public network goes online. Based on the definition of coinmarketcapd, coin refers to a cryptocurrency that can be operated independently; token must rely on other cryptocurrencies as a platform to operate.
Before the public network went online, most cryptographic tokens were ERC-20 tokens based on the Ethereum platform, or side chain projects based on other underlying blockchains. Such tokens did not have the ability to operate and mine independently. capabilities, they are equivalent to temporary tokens on other underlying blockchains and have no real economic value.
But the mainnet launch is different. The project will no longer rely on Ethereum or other side chain projects of the underlying blockchain. Instead, it will have its own independently operating blockchain network and be used by developers and developers as an independent individual. User approval and use.
The launch of the public network means the ecological start of the project, and the follow-upOnly business behaviors that are meaningful will not become a rootless tree.
For example, a large number of DAPPs can be developed on it. The beautiful visions described in the white papers of different public chains have really begun to be tested by users. How to attract more technology developers, absentees (projects using the POW mechanism), and coin holders The participation of investors and the recognition of enterprises and institutions in different industries will bring a great test to the technical and operational capabilities of the project.
So, although the launch of the public network is a milestone, it is only a small step in a long journey of thousands of miles, because the real fight has just begun.

『Wu』Blockchain Digital Currency Exchange

Blockchain technology application research and development, exchange wallet system app development Blockchain technology is actually a new type of Internet. Why is it said to be a subversion of the Internet? Because the Internet solves the problem of information transmission, and the blockchain solves the problem of value transmission. Blockchain has many value transfers, such as distributed ledgers, decentralized trust, smart contracts, etc. So what kind of society will it build in the future?
The answer is: a distributed business and self-disciplined society. The first characteristic of blockchain is decentralization; no third-party intervention is required to realize person-to-person, point-to-point transactions and interactions.
Second, the information cannot be tampered with; once the data information is written into the block, it cannot be changed or revoked.
Third, openness and transparency; within a very short period of time, the block information will be copied to all blocks in the network to achieve data synchronization across the entire network, and each node can trace back all past transaction information of both parties.
Fourth, collective maintenance; in the entire blockchain network, all roles jointly maintain the reliability and security of the entire blockchain information.
Fifth, reliable database; only by mastering 51% of the nodes in the entire system can the blockchain information be tampered with. This is obviously impossible because there are many participants in the entire system and it is extremely costly to master so many nodes. It can't be achieved either.
The characteristics of blockchain bring great opportunities to the financial industry. Using it to transform internal application scenarios in the industry can bring three main benefits:
1) Reduce costs: communication Cost: Centralized trading markets generally require the participation and coordination of multiple parties such as central settlement systems, securities companies, exchanges, and banks. The coordination cost is very high. Through blockchain signature encryption and other technologies, information can be shared and coordination costs can be reduced; Operating costs: Reducing manual labor and paper vouchers, increasing automation through smart contracts, and centralized coordination also bring very high operating costs.
2) Improve efficiency: The settlement cycle is very fast. When the financial transactions realized through blockchain technology are confirmed, it is actually a settlement process that combines clearing, settlement and auditing. The openness, transparency and non-tamperability of the blockchain can save traces of operations, allow supervision records and audit traces to be retained, and facilitate supervision and auditing.
3) Reduce risks: The transaction confirmation on the chain completes the clearing and calculation, greatly reducing transaction risks.Risk blockchain technology application research and development, exchange wallet system app development
Social live broadcast software app development, blockchain trading system development The advantages of IM products on the market, further combined with the characteristics of the blockchain industry, we found that the public is interested in The urgent need for efficient information circulation mainly comes from two different types of groups, project parties and ordinary users, and traditional IM software has been unable to meet their basic needs. For the project side, they hope to have a convenient and efficient tool that can manage a large number of community users, communicate with them accurately and efficiently, and also use the platform to conveniently carry out a series of marketing activities such as airdrops and rewards. For ordinary users, on the one hand, they need to communicate with other users, and they also hope to get direct access to the project party to obtain first-hand project information. At the same time, in view of the protection of personal privacy, security during the message transmission process is also crucial. It would be perfect if you could still gain benefits from this type of participation. How Blockchain benefits us through Blockchain Development Services: Reliable System: When we build data structures using Blockchain, it enables us to make and verify transactions without involving any third party. Therefore, the risk of fraudulent and backdoor transactions as well as inauthentic transactions is reduced. Furthermore, modifications to historical data can only be perceived when a large team is working simultaneously across data centers. In this way, it greatly reduces the possibility of adjusting data and forms a strong ecosystem. Transparent system: Using distributed ledger technology, users have control over all transactions and information because the data in the blockchain is complete, accurate, tamper-proof, and consistent with all members of the network. Mitigating fast transactions: Physical marketplaces with digital documents also take time to execute transactions. Interbank transactions also take a lot of time to clear and time to settle. Here, blockchain can make this a 24/7 process while reducing transaction time to seconds. Instant pay could completely revolutionize industries like energy and transportation. So save wealth by reducing back-office work and automating.

『Lu』 What is blockchain and how to make money with blockchain

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it, someone will register for the exchange through your link and produceIf a transaction occurs, you can get a commission;
4. Mining, "mining" in Bitcoin is the accounting process;
5. Technical support, providing blockchain to some teams and companies Technical support;
6. Open a trading website and charge handling fees;
7. Develop a wallet, which is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain;
8. Be a blockchain project or infrastructure equipment supplier.

『淒』 Why not just close the virtual currency? Trading platform

This is a good question. Since the national laws of cryptocurrency are not allowed, why not just close it? I personally think there are several reasons:

First, although cryptocurrency is not a legal currency, it is a valuable commodity. Since it is a commodity, it should be allowed to be bought, sold and traded freely;

Secondly, as a country, it has every right to do anything. It can close exchanges and bring all relevant personnel to justice. However, I guess the reason why the country has not done so is because blockchain technology is A future direction, what reason is there to ban mainstream cryptocurrencies with real blockchain technology?

Third, from the perspective of currency development laws, cryptocurrency is very suitable as a new generation of legal currency, but it cannot be issued by individuals or arbitrarily organized. However, the decisive cryptocurrency masters such as BTC should And it has the storage value of digital gold.

Fourth, blockchain has not yet been popularized, and the blockchain network has not yet developed to the scale of the Internet. But as long as there is hope, cryptocurrency should be a good store of value and Appreciated commodities exist, and if the country has a mature regulatory system in the future, cryptocurrency exchanges can be included in real supervision and increase tax revenue for the country.

The above personal opinions are for reference only.

Technically speaking, in the world of the Internet, national boundaries are difficult to define. It is difficult for any country to absolutely restrict and ban online transactions.

Legally speaking, the general executive power and judicial power of any countryIt has no extraterritorial effect. Unless all countries in the world reach a consensus, it is impossible to shut down the virtual currency trading platform through administrative orders or judicial rulings.

From an economic point of view, there is no unified consensus on whether the value of virtual currency has more advantages than disadvantages or more disadvantages than advantages.

Yes, China has issued an ultimatum to governments around the world, ordering governments around the world to close the Bitcoin trading market within their respective jurisdictions within 24 hours, otherwise they will bear the consequences.

Regulations of international law. No country is allowed to go to other countries to shut down the local servers of other countries! ! As long as the servers are located outside the country, China has no right to go abroad and shut down the servers abroad.

What happened to virtual currency? Why do you want to shut it down? Don’t you want to see people making money there? You are jealous and jealous... It is not a real currency. It cannot replace the value of currency. It is just a code name. It’s called currency. Is it real currency? Isn't it the same transaction as the stock exchange market? You hate virtual currencies so much, what’s your mentality? Just like the beginning of stocks, you all look at a new thing with a biased and ignorant mentality, treating it as a scourge. Moreover, digital currency has been born for more than ten years, and it is no longer new, it is already old. More than ten years of history have passed, and your thinking is still stuck in the same state as it was decades ago! !

The explosion of the virtual currency market in the past six months has caused many people to focus their attention and funds on the currency circle. As an old leek for many years, I have also left the currency circle for nearly two years. , returned to this market again. However, the market has recently experienced another plunge that nearly halved in just a few days, and one of the direct reasons is my country's policy suppression of the currency circle. So many people will have this question, since our country does not accept virtual currencies, why not just shut down these exchanges so that virtual currencies cannot be traded, thus completely cutting off the circulation of virtual currencies?

In fact, it is not that our country has never done such an action. There is a day in the currency circle that everyone knows and remembers deeply, that is September 4, 2017, known in history as the "94 Incident". The Currency 94 Incident refers to the central bank, together with seven ministries and commissions, completely halting ICOs on September 4, 2017, defining ICOs as illegal financing activities, and domestic exchanges were also shut down. Let’s take a look at the seven ministries and commissions back then: the People’s Bank of China, the Cyberspace Administration of China, the Ministry of Industry and Information Technology, the State Administration for Industry and Commerce, the China Banking Regulatory Commission, the China Securities Regulatory Commission, and the China Insurance Regulatory Commission. The "Announcement on Preventing Financing Risks of Token Issuance" jointly issued by these seven ministries and commissions instantly almost sentenced the currency circle to death. As a result, major domestic exchanges also closed down and moved abroad. This is the largest shutdown event in the history of the currency circle. All exchanges were unable to withdraw coins and cash overnight. The currency circle is sad.Howling, most people are heartbroken, and of course there are some people who have faith in Bitcoin. If you look at everyone’s comments at that time, you will know how tragic the currency circle was at that time. But with the country closed, will the currency world really be completely cool? Facts tell us that instead of cooling off, it hit a record high two months later, with Bitcoin once exceeding $20,000. You must know that this was just more than two months after the "94 Incident" occurred, and this high point will also be the high point in the next three years.

Since all domestic exchanges were shut down before, but the currency circle has not died, there is no longer any domestic virtual currency exchange. Although the world's major exchanges are all run by Chinese, However, their registration, operations, and servers are all overseas. Therefore, our country has no way to shut them down abroad and can only contain them. But with today's Internet technology so advanced, is there really a way to completely block it?

In fact, what I want to say is that our country has frequently attacked virtual currencies. On the one hand, it is to allow people to avoid excessive risks, and on the other hand, it is also to make virtual currencies better and more profitable. healthy development. I believe that the country must also know that it is better to block than to open up. This is why our country will issue digital renminbi. But the currency circle is too chaotic. If this market is opened rashly without regulations, then there will definitely be big problems in this market. So in the future, I think the country will actively explore the regulatory rules of the currency circle. Under formal national supervision, There will definitely be an exchange that truly belongs to our country. But the road will be long. This point can be referred to the foreign exchange margin business. Although foreign exchange margin business is conducted all over the world, our country has not opened this market to ordinary people, but can it never be opened? Obviously impossible.

It is impossible to close them all because there are too many. According to statistics, there are more than 1,000 digital currency exchanges or more, and most of them are not in China. How can you close them? Unless there is a consensus among global countries to shut down, this is basically impossible. It is legal in the United States. If you want to close digital currency exchanges, you can only close domestic ones. However, it is unlikely. Oyi, Huobi, and Binance are There are servers overseas that have been shut down, but they cannot be used in China.

Digital currency is a trend and an emerging behemoth built on the Internet. Blockchain technology is also known as the next generation of value Internet. Blockchain applications are very wide. At present, , artificial intelligence, Internet of Things, virtual reality, government affairs, etc. will all use blockchain technology in the future, and exchanges are the trading bridge for digital currencies, and you can also understand them as value channels.

At present, the top three most popular exchanges known to Chinese people are actually arranged by the Chinese. One of them, Zhao Changpeng, Li Lin, and Xu Mingxing, I predict that after this round of bull market, among them, A man has become the richest man in China. Just look at the daily transaction volume, handling fees and frequency.Calculate it yourself.

In short, it is absolutely impossible to close exchanges, because all exchanges are not only what you know in China, but what you know in China is only the tip of the iceberg.

Since it cannot be blocked, the final result is that you have to keep up or be abandoned by the times. Just like Bitcoin, if it can be blocked, it can be destroyed. It was destroyed as early as 2010 when it was in its infancy. .

Finally, even if the exchange is closed, it can only be closed domestically, and it is basically useless for other countries internationally. After all, if you don’t eat this big cake, there will be too many people eating it.

China has officially banned all trading platforms, all of which are outside the country. But can you go to Wall Street to shut down a U.S. listed company like Coinbase? We must first defeat the country where the global platform is located [tears]

The question you asked is so funny, it’s like asking why China doesn’t cancel U.S. dollar transactions. Mainland China has not done so for a long time. With the trading platform, all trading servers are legal in foreign countries. The only thing that can be done now is to prevent Chinese people from using the payment system. What is the use of banning? The more banned, the greater the backlash. Whoever you want to send your money to is voluntary, and others and even national laws have no right to interfere. Investment is risky. Virtual currencies are not legal in China. All investment risks are borne by yourself.

The existence of all things is reasonable, and the same applies to virtual currencies. Closure is not the purpose; rectification, making it formal, and a fair and just trading place is the way to ensure the safety of citizens' property.

In the era of the gold and silver standard, it is impossible to create a virtual currency like Bitcoin, because the credit guarantees of various countries and currencies that can be exchanged for gold and silver are valuable currencies. Bitcoin is just a string of numbers and has no value or convertible equivalent. Therefore, there will be no virtual currency during the gold standard period, and it is even less likely to be like the embarrassing situation today where the market value of one Bitcoin exceeds US$1 trillion and the price of one Bitcoin exceeds US$40,000.

However, before 1971, the US dollar was pegged to gold. After the Bretton Woods system was abolished, the US dollar was decoupled from gold. At that time, 35 U.S. dollars was exchanged for 1 ounce of gold, but 50 years later, it became close to 2,000 U.S. dollars for 1 ounce. In 50 years, the U.S. dollar became more than 50 times relative to gold. The currencies of other countries have devalued even more. From the credit of each country to the gold link, it has become an outcome of credit plundering.

As the saying goes, things must be reversed when they go to extremes. Although virtual currencies such as Bitcoin do not have a string of numbers that guarantee the credit of various countries. However, it is recognized by participants such as capital, enterprises, investors and exchangers. This kind of recognition cannot be turned off just because you want to. As long as there are a few places where virtual currencies can be exchanged or freely exchanged in the online world, then there is no way to put an end to it and prohibit it. At most, we can only expect it.have a restrictive effect. If you want to eliminate Bitcoin, you must start with the gold and silver standard of national credit currency, but this is gone forever. Similarly, virtual currencies have also gained a foothold and are difficult to truly eradicate. A war between digital virtual currencies and the credit currencies of various countries has begun. Only by adopting a more restrained approach to relative currency preservation and allowing countries’ currencies to move toward more convenient digitization can we better combat virtual currencies such as Bitcoin’s seizing market share. The harm of drugs is so serious, but it is still the same as repeated abstinence and difficulty in curing it!

『8』Aren’t blockchain transactions anonymous? Why do exchanges need identity authentication?

Identity authentication comes from the KYC system. First, let’s talk about what KYC is. KYC (know-your-customer) is a basic system in the financial industry. Traditional financial institutions will require customers to provide identification, location, employment certificate, income and other information, mainly to comply with anti-money laundering and the Anti-Terrorist Financing Rules (AML-CFT), while the requirements for cryptocurrency exchanges are relatively low, generally only requiring real-name authentication.
Ordinary users conduct cryptocurrency transactions through exchanges. Centralized exchanges basically require KYC. Although there are already decentralized exchanges that do not require KYC, they have few users, poor liquidity, and Compared with centralized exchanges, they are still non-mainstream (although Binance DEX is a decentralized exchange, it also requires KYC). This has also resulted in KYC becoming a step that users must go through to enter the crypto market.
Many people have doubts about this. Does KYC violate the decentralized spirit of cryptocurrency? Will their KYC information be abused? The author believes that these two points are not contradictory. Although cryptocurrency is decentralized, the exchange itself is not. In today's chaotic currency circle, KYC is still necessary.
The purpose of KYC by exchanges is to ensure that only qualified people can use a service and to prevent minors, illegal elements or users from countries that do not provide services from using it.
At the beginning, many exchanges did not require KYC. At that time, the encryption market was still very weak and did not attract the attention of regulatory authorities. However, as the size and influence of the encryption market grows, the government can no longer continue to ignore it. Regulators in various countries have introduced policies to incorporate the cryptocurrency industry into the traditional financial supervision field. The price of cryptocurrency compliance is having to adhere to strict KYC/AML-CFT regulations.
The anonymity and transnational circulation of cryptocurrency make it very suitable for use in various illegal activities. This is also a very powerful excuse for anti-crypto people to attack Bitcoin. During the Libra hearing, both Trump and the U.S. Treasury Secretary focused on this issue. The AML-CFT rules are a system designed to prevent criminals from being used by criminals involved in illegal activities such as terrorist financing and money laundering.
Of course, the implementation of KYC by exchanges is not entirely due to policy reasons, but also for security reasons.A big motivator. If an exchange allows anyone to trade without verifying their identity, it will easily attract criminals and become a breeding ground for money laundering and fraud. After KYC, the exchange can grasp the true identity of the users and find them if there is a problem, which is conducive to combating crime and protecting the security of user assets.
KYC also plays a role in suppressing fraudsters and fake accounts. In order to attract new and active users, many exchanges have various activities such as airdrops, invitation rebates, and trading competitions. Without KYC, the wool party can register a large number of accounts at almost zero cost through the code receiving platform, but KYC has raised the threshold a lot, which is also the way many platforms now combat the army of account swiping.
The method that takes into account both privacy and KYC does not yet exist. In order to ensure the interests of exchanges and customers, it is foreseeable that the current KYC model will continue to exist for a long time.
As users, we can only improve our security awareness. In order to ensure the security of KYC information as much as possible, we must choose a large and guaranteed trading platform. The KYC systems of these exchanges are more complete and are relatively safer. In addition, information such as watermarks and timestamps can be added to the image before submitting KYC information, so that the harm of leakage is very limited.

『九』 I have a blockchain exchange, but I don’t understand how to explain blockchain to others

Let us assume that the villagers Lao Wang and Xiao Li personal. Lao Wang borrowed some money from Xiao Li, and Xiao Li wrote it on an IOU signed by both parties. A few days later, Lao Wang denied the existence of the loan and claimed that Xiao Li had forged the paper. Xiao Li couldn't argue because he found it difficult to prove that Lao Wang actually owed him money.

In this example, Lao Wang and Xiao Li are two nodes.

Now assume the same scenario, with many pairs of people trading with each other in the village. The only evidence for each pair is the IOU. If one party fails, it will be very difficult. Seeing this scene, the village chief came up with a solution. He suggested using a common notebook for the entire village and recording transactions in it. Because the village chief is highly respected, the villagers unanimously decided that the village chief should keep this important transaction book. Every time a transaction is made, the villagers go to the village chief's house to have the village chief witness and record each transaction. Each transaction is written into a notebook and then kept safely. That notebook can be called a database.

Because this notebook was so important, the village chief locked it in a safe. However, there are always some problems here. Sometimes, the village chief accidentally spills ink on the paper, making part of the transaction record illegible. This is called a single point of failure. The thief knows that there is an important notebook in the safe of the village chief's house, and goes to great lengths to steal it. This is called hacking.

Until one day, the village chief’s son owed a lot of money to others, so the village chief secretly deleted his son’s debt entry. In this way, the village chief's son "doesn't owe money."

When the villagers learned about this, they began to question the village chief's fairness and authority. So there isPeople came up with new ideas:

Abolish the power of the village chief. This is called decentralization. Let all villagers keep a notebook, and the transaction records are copied and dispersed. This is called a distributed database. Therefore, if there are n people in the village, there are n notebooks, that is, n nodes. Every time a transaction is made between any two people, all the people in the village gather together and record it in their respective notebooks. And no one can cover the sky with one hand. This is called decentralization.

They also decided to never delete the mentioned transactions from the notebook, which is irreversible. For example, if Lao Wang borrowed a sum of money from Xiao Li before, but in the blink of an eye he wants to return the money, then the transaction book will not delete the previous loan record, but write a new repayment record, so there are two Records.

Let's try to break this rule next. What if we bribed Lao Wang to change the records in his notebook? Not feasible, because at the next village meeting, it was found that what Lao Wang’s notebook wrote was different from everyone else’s, so the villagers noticed that Lao Wang might be doing something wrong. According to the transaction described, it was decided to abolish Lao Wang’s transaction records and kick Lao Wang out of the organization.

What if you try to bribe all the villagers? The price is too high.

The characteristic of this model is that greedy people need to pay a lot of money to attack the rules. He will find it more profitable to follow the rules.

A smart kid in the village suggested that each transaction data be called a "block" and strung into a "chain" in chronological order, which is called a blockchain.
