1. Is blockchain a scam?

Blockchain is a scam. I hope that everyone will not rush to invest in those Ponzi schemes, and do not have fantasies and fantasies, because the window of time to get rich overnight has long been closed, and the ordinary people who come in now are very miserable and will be cut off. , everyone must respond to the government’s call and not be defrauded of illegal fund-raising.

2. Is blockchain a pyramid scheme? Be careful of scammers using new technologies to defraud.

Many people are not clear about the name blockchain, and some even suspect it is a pyramid scheme. So the question is, do you understand the definition of blockchain? Do you think blockchain is a pyramid scheme? Some citizens have reported that some people use blockchain to commit fraud, and some people have been defrauded of a lot of money. So, does this mean that blockchain is unreliable?

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", created a reliable "cooperation" mechanism, and has broad application prospects.

It is understood that blockchain is a new technology and is not a disguised MLM. It is just claimed by many MLM organizations as "blockchain". In fact, there is no technology and it is just called "blockchain". "It's just a pyramid scheme, and the state has issued announcements many times to crack down on this type of pyramid scheme.

However, I hope everyone understands that blockchain is high technology and a new technology that has brought many changes to society. However, in order to make money, scammers set their sights on the blockchain, and their purpose is to use the blockchain to defraud. Therefore, everyone must be careful of similar scams. Before investing in a project, you must investigate to see if it is legitimate and reliable.

I once again remind you that blockchain is just an underlying technology of the Internet and has nothing to do with pyramid schemes. Because many people don’t understand it, many people use the slogan of blockchain to carry out pyramid schemes to illegally raise funds. . In fact, to identify MLM, you need to look at three characteristics:

1. Entry fee. Whether it is necessary to subscribe for goods or pay fees to obtain the qualifications to join or to develop the qualifications of others to join to obtain illegal benefits; 2. Pulling people. Whether it is necessary to develop others to become one's downline, and pay the personnel developed based on the number of people they develop directly or indirectly on a rolling basis to seek illegal benefits; 3. Remuneration method. Whether remuneration is calculated based on the sales performance of direct or indirect development personnel to seek illegal benefits. If it meets the above characteristics, it may be suspected of pyramid schemes.

3. Is how to make money with the blockchain a scam?

It is not a scam. Generally speaking, the blockchain is still in its infancy, and many projects have not yet been implemented. Only by respecting the law of growth Under the premise of being down-to-earth andOnly by nurturing it step by step can it gradually mature. Technology is neutral, but it is human nature that determines the direction and outcome of technology. How blockchain and digital currency will develop in the future depends on the values ​​​​and civilization of the controller.
Blockchain can allow you to make money in this industry, but it can also make you bankrupt. Therefore, I would like to remind users that they need to be cautious when investing. Don’t let yourself get involved without making money, and the gain outweighs the loss. There are also many blockchain scams. We must also be more vigilant to avoid being deceived and causing unnecessary economic losses.
Expand information
Pre-loan stage
Blockchain technology can first be applied to the logistics supply chain to help banks and other lending institutions more comprehensively and accurately grasp the real main business, transaction background, and financing of small and micro enterprises. Downstream affiliated enterprises, as well as their negotiating position in the supply chain, product sales, rhythm and path of payment, etc., on the one hand, help more asset-light, high-growth and high-quality enterprises obtain financing support through transaction bills, logistics documents, etc. On the one hand, it prevents problematic enterprises from falsifying their business background and capital needs to obtain loans.
In addition, blockchain can also be applied to the provident fund interconnection to help banks understand the actual payment status of social security, provident fund, etc. of shareholders, executives, and ordinary employees of borrowing companies, so as to reasonably evaluate the size of the company's personnel and operating conditions, and provide credit and loans. Provide sufficient basis for approval decisions.
Loan stage
Blockchain technology can be applied to corporate loan information review and mortgage and pledge review to help banks improve approval efficiency and ensure approval quality. In the financing process of enterprises, especially small and micro enterprises, they often need to provide contracts and other necessary materials. Paper-based contracts with multiple signatures and seals are not only inefficient, but also have a series of problems such as forgery, alteration, and false signatures, which bring problems to bank approval. Greater counterfeiting, fraud and credit risks.
With the support of blockchain technology, relevant real-name information subjects, orders and ordering processes, electronic contracts, agreement signing processes, subsequent supplementary agreements, and photo materials can be preserved in real time, and all stored certificates cannot be tampered with. Ensure that the bank quickly authenticates and approves, and efficiently resolves disputes when they arise. In addition to traditional real estate, other assets owned by enterprises and business owners, including bank financing and other financial assets, can also be used for transfer and pledge, becoming a qualified basis for credit enhancement that can be accepted by banks, improving the availability and immediacy of corporate credit. .
Post-loan stage
Blockchain technology can be applied to the timely assessment of an enterprise's production and operation status and ability to perform repayments, helping banks to effectively grasp credit risks and adjust post-loan risk control strategies at any time. In past business practices, banks often neither fully understand the true market value of mortgages and pledges, nor can they well judge the impact of an enterprise's operations in warehousing and exiting on the market value of remaining mortgages and pledges. The ability to control new loan types such as warehouse receipt pledges is relatively low.
After switching to digital warehouse receipts supported by blockchain technology, product quality, quantity, specifications, photos and other information can be completely and standardized on the chain, and authenticity and traceability are fully guaranteed., banks can technically prevent enterprises and warehousing institutions from fictitious warehouse receipts, warehouse receipts and incoming and outgoing warehouse information are inconsistent, etc., to ensure that post-loan management is effective. In addition, information such as factory buildings and office building leasing of borrowing companies can also be fully shared with banks, upstream and downstream enterprises and other intermediary service agencies through blockchain technology, minimizing the risk of money being lost and other issues such as "people leaving the building empty".

4. Is blockchain a lie?

"Blockchain" is an important concept in the new era. It is essentially a centralized database. It is also the underlying technology such as digital currency. According to our popular explanation, the "blockchain" can be regarded as a ledger, and each bill is a block. However, this ledger is centralized, and it can be said that no company or team has jurisdiction over it. "Blockchain" technology is a unique informatization that is centralized and cannot cross-change information. Now in daily life, this technology has been applied to a series of applications such as electronic invoices and payment codes.
In today's life, many people use this guise to commit fraud. Direct sales disks, capital disks, technology disks and other names are used to lure people to make money and then run away. As a result, many people have lost their funds and have nowhere to defend their rights. In the end, I can only say that "blockchain" is a lie. There is no right or wrong in technology, it’s the people who are wrong.
With the progress of the times and the progress of society, the initial application of any technology will be subject to various positive and negative doubts. However, with the relative application and maturity of technology, coupled with the improvement of technology, various aspects around people have formed. This application will continue to improve, and I believe that these doubts will slowly dissipate in the near future.
The following is a summary of some blockchain scams that are often around you!
Trap 1: Blockchain is about issuing coins to make money
Trap 2: Conducting virtual currency transactions, promising low investment and high returns
Trap 3: Decentralization can solve all problems
Trap 4: With the extension of the blockchain, you can make money with a mining machine
Trap 5: Transactions on WeChat and Alipay to buy and sell virtual currencies
In short, the methods of scammers are also advancing with the times. Through our "eyes of wisdom", we can improve and enhance our adaptability, discover and alert ourselves, and prevent being deceived. Investors must be wary of various deceptive methods that offer low investment and high returns.

5. Is blockchain a lie?

China’s blockchain development is uneven and wild. As of August this year, the development level of my country’s blockchain industry is at the forefront of the world. , the total number of enterprises ranks second in the world after the United States. Monitoring data from the National Internet Emergency Center’s Key Laboratory of Internet Financial Security Technology shows that there are approximately 32,000 companies with the word “blockchain” or whose business involves blockchain. Chain technology companies only account for about 10%, or even less than 10%.

In other words, there are many organizations committing fraud under the guise of "blockchain"!

Liar routine:

Basic routine:High-yield high-yield slogans

Promotional rhetoric: "You can make a lot of money while lying down!"

The essence of the scam: So-called "projects" that use professional terms to claim high profits raise funds from victims , the essence is financial fraud.

Intermediate routine: play with the concept and get high dividends

Promotional rhetoric: "The benefits of the sharing economy are considerable"

The essence of the scam: illegal fund-raising (such as "Qubu" APP )

Advanced routine: high rebates for currency speculation

Promotional rhetoric: "Virtual asset financial innovation"

Scam essence: illegal pyramid schemes (such as various "digital "Coin" investment project)

6. Is the blockchain investment platform a scam?

Blockchain The investment itself is not a scam, but it may become a scam because of its opaque price formation mechanism, which can easily cause huge losses to investors and lack of supervision. If investors are defrauded due to blockchain investments, they can defend their rights against the exchange and project parties. Any behavior that constitutes fraud or other crimes should be reported promptly, and the judicial authorities will hold them accountable for their corresponding criminal responsibilities.
[Legal Basis]
Article 3 of the "Criminal Law of the People's Republic of China" If the law expressly stipulates that the act is a crime, it shall be convicted and punished in accordance with the law; if the law does not expressly stipulate that the act is a crime, it shall not be convicted and punished. Article 13 All activities that endanger national sovereignty, territorial integrity and security, split the country, subvert the power of the people's democratic dictatorship and overthrow the socialist system, undermine social and economic order, infringe upon state-owned property or property collectively owned by the working people, and infringe upon the private rights of citizens All property, infringement of citizens' personal rights, democratic rights and other rights, as well as other behaviors that are harmful to society and should be punished according to the law are crimes, but if the circumstances are obvious and minor and the harm is not great, they are not considered crimes.

7. Is blockchain a disguised pyramid scheme?

Blockchain is a new technology and is not a disguised pyramid scheme. It is only claimed by many pyramid schemes to be "blockchain", but in fact it is not. It does not have any technology, it is just a pyramid scheme in the name of "blockchain". The country has issued multiple announcements to crack down on this type of pyramid scheme. The following is Xinhuanet's report on blockchain MLM:

Blockchain is not equivalent to virtual currency, and there are also security risks. Behind the popularity, there are exaggerated publicity campaigns with "ulterior motives". Only by removing the flashiness can the blockchain return to its true application value.

Invest 80,000 yuan and it will become 800,000 yuan in three months? Shenzhen police uncovered a huge fund-raising fraud case. Under the guise of blockchain concepts and 10 times earnings, thousands of investors have fallen deeply into it, with the amount involved reaching 307 million yuan. Under the "mysterious veil" of the blockchain, criminals have taken advantage of the opportunity to use their tricks, and the blockchain has become a "signature" for economic crimes such as fraud and pyramid schemes.

Why has the blockchain been repeatedly “misused” by illegal activities such as pyramid schemes and fraud? Apart from being “unclear”, what is the “function” of blockchain technology itself? Since this year, with theIntensified supervision and the cooling of currency speculation have brought new opportunities to the development of blockchain. How is the implementation of blockchain commercial "applications" now? Reporters from "Lookout" News Weekly recently conducted an investigation into this.

When the three-month "fund release period" promised by the trading platform expired and the staff started "kicking" people in the QQ group, Tang Haiyan, who lives in Bao'an District, Shenzhen, realized that she might have been cheated. .

Previously, Tang Haiyan invested 80,000 yuan to buy a virtual currency called "Puyin Coin" under the introduction of a classmate. "The other party said that this currency is the most advanced blockchain technology at the moment, with Tibetan tea as collateral, and he also showed me a 'technical white paper'. I didn't understand blockchain, so I didn't read it carefully."

Although he doesn’t know much about blockchain or virtual currencies, Tang Haiyan is full of expectations for the high investment returns. She told reporters that the company that issued the "Common Silver Coin" would regularly split the virtual currency at a ratio of 1:10, which means that each split would increase the value of the "Common Silver Coin" in the hands of investors by 10 times. . As long as it is split once, the 80,000 yuan she invested is equivalent to buying "common silver coins" worth 800,000 yuan, and she can get huge profits by selling them on the trading platform.

According to the rules of the trading platform, the "common silver coins" just purchased cannot be traded immediately. They must be frozen on the platform for three months before the "release period" can begin. However, when three months passed, Tang Haiyan not only failed to double her assets, but also the 80,000 yuan frozen on the platform could no longer be used for transactions.

“Other investors began to question the authenticity of this investment in the QQ group. As a result, the company staff kicked these investors out one by one. I felt bad.” She said.

Facts also proved Tang Haiyan’s intuition. At the end of March 2018, Shenzhen police uncovered a huge fund-raising fraud case, with the amount of fraudulent funds reaching 307 million yuan. In this case, the Shenzhen Puyin Blockchain Group Co., Ltd. involved in the case used the "blockchain + Tibetan Tea" model to issue virtual currency and defraud public deposits. Tang Haiyan was one of thousands of victims. .

Shenzhen police investigation found that the company claimed that investors could put "common silver coins" on the virtual trading platform "Jubi.com" to earn the price difference

. In fact, the change in its buying and selling price was caused by the company using investors' investment funds to perform behind-the-scenes operations, and once raised the price of "common silver coins" from 0.5 yuan to 10 yuan, allowing investors to taste some sweetness. When a large number of investors entered the market, the company continued to cash out by maliciously manipulating the price trend of "Common Silver Coins", which eventually resulted in the "Common Silver Coins" in the hands of investors being worthless.

Since 2018, engaging in fraud and pyramid schemes under the banner of blockchain has become a commonly used "routine" in new criminal methods. In April 2018, Jinan police busted a pyramid scheme gang under the guise of "western development", "national poverty alleviation", "original stocks", "blockchain" and "e-commerce", and arrested the main suspect.There were more than ten suspects, more than 100 accounts involved in the case were frozen, and more than 300 million yuan of funds involved in the case were seized.

Jinan police introduced that Huileyi e-commerce company designed fake virtual disks on the Internet and released so-called "treasure coins" and "precious coins" on the grounds that the country is vigorously developing the big data industry. and other virtual currencies.

They first use the gift as a guise to give a certain amount of virtual currency to newly joined MLM personnel, with the price of each coin being tens of yuan, and then use artificial manipulation to increase the value of the virtual currency to more than 100 yuan or even hundreds of yuan. Yuan, attracting people who do not know the truth to join, and finally "cut leeks" through the cyclical fluctuations of the so-called "devaluation" of virtual currencies, repeated over and over again, and ultimately achieve the purpose of seeking illegal benefits.

In Xi'an, the local police also successfully cracked a huge online pyramid scheme under the banner of blockchain. According to the police, the criminal suspect Zheng paid a high salary to organize network platform administrators Zhang, Li and other 9 people. Since March 28, 2018, he has used collective pyramid schemes and online pyramid schemes as means to sell coins at a price of 3 yuan each. Sell ​​virtual "Datang Coins" on the "Consumption Era" online platform and control the appreciation rate;

At the same time, hold promotion meetings in multiple cities at home and abroad to attract members, and set up There are 28 levels of agents in charge. In just 18 days, the gang has developed a total of more than 13,000 registered members. It has been found that the case involves 31 provinces, municipalities, and autonomous regions across the country, and the funds involved are as high as 86 million yuan.

The "Tencent 2017 MLM Situation Awareness White Paper" released by Tencent Security Joint Laboratory stated that in recent times, various overseas capital disks, virtual currencies, ICO (blockchain project initial public offering of tokens) Financing) projects emerge in an endless stream, which hide many risks such as illegal issuance, false projects, cross-border money laundering, fraud, pyramid schemes, etc., causing a large amount of funds to flow overseas. Once they collapse, run away, or lose contact, investors often have no way to complain and lose money. recover. For example, Baichuan Coin, Mark Coin, Beta Coin, Dark Coin, etc.

Reporters from "Lookout" News Weekly conducted interviews in Guangdong, Shandong, Shanghai and other places and learned that most people know that the concept of blockchain is very popular, but they are "uninformed" about the specific functions of blockchain. There are different opinions: some people think it is used for "investment and financial management" and "buying and selling currency", while others think it is "a major invention of the same magnitude as the steam engine". Some entrepreneurs are gearing up to seize this "once-in-a-lifetime opportunity to get rich."

Many people in the industry said that it is precisely because people have many misunderstandings about blockchain that criminals have the opportunity to fish in troubled waters and mislead investors.

First, blockchain is not equal to virtual currency. As of the end of last year, the number of domestic ICO participants and total transaction volume had doubled. A large number of digital currency exchanges have fled overseas, and the agency investment model has involved more ordinary people in high-risk investments.

Many industry self-media and famous speakers have formed interest alliances with issuers and digital exchanges to endorse and create the "Air Coin" project platform.public opinion. In December last year, the People's Bank of China and nine other departments characterized ICOs as "suspected of illegal fund-raising, financial fraud, pyramid schemes and other illegal and criminal activities."

During the interview, many people told our reporter that the existence of tokens has built a set of equity mechanisms for the development of blockchain technology. This mechanism is indispensable for stimulating the prosperity of blockchain applications. of. "Market practice in the past five years has proven that blockchain applications without equity mechanisms are like computers without Internet connectivity and a market economy without currency. The application scenarios and development speed are greatly reduced." said an investor in Shanghai. .

In fact, tokens represented by Bitcoin are only one of the earliest products to verify blockchain technology. There is no equivalence between the two, and the existence of tokens has already affected the blockchain technology. The development of the chain has obvious negative effects.

Xiao Wei, chief engineer of the Internet Blockchain, told this reporter that the myth of ICO getting rich has shaken the R&D efforts of blockchain technology talents, and the myth of getting rich through coin speculation, which can easily return hundreds of times, is testing the blockchain industry. The patience of chain technology R&D talents. "Many of the 'comrades' in the circle who used to do blockchain technology research and development together have switched to issuing coins, and now there are very few who can continue to do technology research and development and application."

Beijing Internet Finance Industry Xu Zewei, secretary of the party committee of the association, said that under the background of China’s ban on ICOs, many domestic start-up companies promoting blockchain applications are “selling sheep’s heads to dogs”, packaging originally worthless tokens through conceptual packaging to attract money for financing. “ICO has polluted the good atmosphere for innovation and entrepreneurship and created a speculative product. Many young people do not think about starting a business, but they are thinking about issuing coins, which gives everyone the illusion of getting rich overnight.”

< p>At present, more and more people in the industry are beginning to think about whether the development of blockchain must rely on the issuance of tokens to achieve incentives. Guo Dagang, secretary-general of the Beijing Internet Finance Industry Association, told this reporter that the so-called incentive mechanism is just a theoretical basis for project parties to issue tokens. Huo Xuewen, director of the Beijing Municipal Financial Affairs Bureau, also believes that if the blockchain does not get rid of the currency issuance dilemma, it will never find a legal implementation mechanism.

Secondly, blockchain is not a panacea and there are risks to its security. Blockchain is generally considered to be able to achieve three functions:

First, the data stored on the blockchain cannot be tampered with or forged, and the data has high credibility and credibility; second, The entire transaction process is traceable, enabling accurate tracking of responsibilities; third, smart contracts embedded in the blockchain can be automatically executed based on the contract, thereby improving work efficiency and reducing the risk of default. The industry generally believes that blockchain has broad application prospects in finance, logistics, trade and other fields.

In fact, blockchain is not omnipotent, and its functions also have many limitations. It is generally believed that based on its cryptographic characteristics, if you want to tamper or forge on the blockchain, you theoretically need to control more than 51% of the nodes to achieve it. When there are enough nodes in the blockchain, this trust creation mechanism with widespread public participation will be difficult to tamper with.

However, in reality, digital goodsCoin exchanges are frequently attacked or even stolen. On June 20, 2018, South Korea's Bithumb exchange announced on its official website that the exchange was attacked by hackers and cryptocurrency worth 35 billion won, or approximately US$32 million, was stolen.

Ji Xinhua, known as China's first generation "hacker", said that the blockchain will continue to face attacks, and the process of uploading data to the chain is prone to information leakage. Some people in the industry are also worried that once the super computing power of quantum computing is realized, it will also have a direct impact on the blockchain.

Zhao Yao, a special researcher at the Institute of Finance of the Chinese Academy of Social Sciences, told this reporter that as early as 2013, the academic community confirmed that the blockchain is not perfect and there are many "cheating" strategies. As long as there are sufficient economic incentives, attacks that control more than 51% of the nodes do not only exist in theory.

Zeng Guang, secretary-general of the Shenzhen Internet Finance Association, said that blockchain technology itself is not irreplaceable or subversive. "Some criminals exaggerate the role of blockchain to illustrate that blockchain has huge investment value, which deserves the vigilance of investors."

Thirdly, the popularity of blockchain is not the same. Not entirely true. Data shows that from the end of 2017 to the beginning of 2018, more than 300 self-media companies mainly focused on ICO projects appeared, which became an abnormal phenomenon worth noting.

“Most of these self-media have received financial support from exchange leaders and investors in the currency circle. It is difficult to guarantee the objective independence of their reports. Most of them advocate ICO and currency speculation, and excessively promote digital currencies. Prospects, creating convenience for the spread of public opinion for illegal fund-raising of problematic projects." Xu Zewei said that some blockchain self-media investors are themselves ICO project investors, and their profit model is to charge soft article fees and project promotion fees, becoming a token issuance Public opinion helpers, and some media have developed into agency investment agencies to make profits from it.

(7) Is Blockchain Pirate Coin a scam? Further reading:

On August 24, 2018, the China Banking and Insurance Regulatory Commission website issued a risk warning reminding The general public is advised to guard against illegal fund-raising in the name of “virtual currency” and “blockchain”.

The original text is as follows:

Risk reminders on preventing illegal fund-raising in the name of "virtual currency" and "blockchain"

China Banking and Insurance Regulatory Commission, Central Cyberspace Affairs Commission , the Ministry of Public Security, the People's Bank of China, and the State Administration for Market Regulation remind:

Recently, some criminals have issued so-called "virtual currencies" and "virtual assets" under the banner of "financial innovation" and "blockchain". "Digital assets" and other methods to absorb funds and infringe on the legitimate rights and interests of the public. Such activities are not really based on blockchain technology, but are actually hyping up the blockchain concept to conduct illegal fund-raising, pyramid schemes, and fraud. They mainly have the following characteristics:

1. Obvious networking and cross-borderization. Relying on the Internet and chat tools for transactions, and using online payment tools to receive and disburse funds, risks have a wide scope and spread quickly. Some criminals rent overseas servers to buildThe website essentially carries out activities for domestic residents and remotely controls the implementation of illegal activities.

Some individuals claim in chat tool groups that they have obtained investment quotas for high-quality overseas blockchain projects and can invest on their behalf, which is most likely a fraudulent activity. Most of the funds for these illegal activities flow overseas, making supervision and tracking very difficult.

2. Strong deception, temptation and concealment. They use hot concepts to create hype and fabricate numerous "high-level" theories. Some even use celebrity V's "platform" propaganda, and use airdrops of "candy" as temptations, claiming that "currency values ​​only rise but not fall" and "the investment cycle is short. "High returns, low risks", which is highly deceptive.

In actual operation, criminals illegally make huge profits by manipulating the price trend of so-called virtual currencies behind the scenes and setting profit and withdrawal thresholds. In addition, some criminals also issue tokens in innovative forms such as ICO, IFO, and IEO, or conduct virtual currency speculation in the form of IMO under the banner of the sharing economy, which is highly concealed and deceptive.

3. There are various illegal risks. Through publicity, criminals use "static returns" (profits from currency appreciation) and "dynamic returns" (profits from offline development) as bait to attract the public to invest funds, and induce investors and development personnel to join in, constantly expanding the capital pool. , with characteristics of illegal fund-raising, pyramid schemes, fraud and other illegal activities.

Such activities use "financial innovation" as a gimmick, but are essentially a Ponzi scheme of "borrowing new and repaying old", making it difficult to maintain long-term capital operations. The general public is requested to view the blockchain rationally, do not blindly believe in promises made by the public, establish correct currency concepts and investment concepts, and effectively improve risk awareness; they can actively report to relevant departments any clues about illegal crimes discovered.

8. Is blockchain investment true or false?

Legal objectivity:

Article 123 of the Civil Code of the People's Republic of China, civil subjects enjoy intellectual property rights in accordance with the law. Intellectual property rights are the exclusive rights enjoyed by obligees in accordance with the law with respect to the following objects: (1) works; (2) inventions, utility models, and designs; (3) trademarks; (4) geographical indications; (5) trade secrets; 6) Integrated circuit layout design; (7) New plant varieties; (8) Other objects specified by law.

Legal subjectivity:

Blockchain technology itself is not a scam, but it does not rule out that some people use blockchain as a cover to commit scams. Several problems exist in blockchain: 1. The problem of excessive blockchain size. With the development of blockchain, the volume of blockchain data stored by nodes will become larger and larger, and the storage and computing burden will become increasingly large. The heavier. Taking the Bitcoin blockchain as an example, the size of its complete data currently reaches about 71GB. If a user uses the Bitcoin Core client to synchronize data, it may not be possible to complete the synchronization for three days and three nights. Moreover, the data of the blockchain The volume is still increasing, which brings a great threshold to the operation of the Bitcoin Core client. 2. The problem of blockchain data confirmation time. In current blockchain systems, especially in financial blockchain systems, there is a time limit for data confirmation.long time problem. Taking the Bitcoin blockchain as an example, the current confirmation time of a Bitcoin transaction takes about 10 minutes. In the case of 6 confirmations, you need to wait for about 1 hour. Of course, for credit card transactions, the confirmation time is 2 to 3 days. Bitcoin has made great progress, but it is still far from the ideal state. 3. Dealing with the problem of transaction frequency The blockchain system faces the problem of too low transaction frequency. Taking the Bitcoin blockchain as an example, the average size of each transaction is about 250 bytes. If the block size is limited to 1MB, the number of transactions that can be accommodated is 4,000. Calculated at the rate of one block every 10 minutes, 144 blocks can be generated every day. Yunzhou can accommodate 576,000 transactions. Divided by the number of seconds per day, 86,400, the Bitcoin blockchain can process up to 6.67 transactions per second. trade. Currently, the actual daily transaction volume on the Bitcoin blockchain is close to the system bottleneck (picture). If the expansion problem is not resolved, it may cause congestion and delays in a large number of transactions. Average number of transactions in Bitcoin blocks (Source: Block Yuan) In comparison, Paypal's overall number of transactions in the third quarter of 2013 was 729 million, with an average of 93.75 transactions per second. Information from the official website of VISA, the world's largest payment card, shows that VisaNet achieved a processing capacity of 47,000 transactions per second in a 2013 test. Compared with several major payment networks such as Alipay, the Bitcoin blockchain is more like a newborn baby in terms of transaction processing frequency. Of course, this was also an early deliberate design by Satoshi Nakamoto. The Bitcoin block size was limited to 1MB to avoid the malicious behavior of rogue miners and have a negative impact on people. Bitcoin blockchain payment The reason why the Internet has grown to be worth billions of dollars today is that it is decentralized. 4. The development of blockchain is restricted by the current system. On the one hand, the decentralized and autonomous characteristics of blockchain dilute the concept of national supervision and have an impact on the current system. For example, digital currencies represented by Bitcoin not only pose a challenge to the country's right to issue currency, but also affect the transmission effect of monetary policy, weakening the central bank's ability to regulate the economy, causing monetary authorities to remain cautious about the development of digital currencies. On the other hand, regulatory authorities also lack full understanding and expectations of this new technology, and the establishment of laws and systems may lag behind, resulting in a lack of necessary institutional norms and legal protection for economic activities related to the use of blockchain, which inadvertently increases reduce the risks of market entities. 5. The integration cost of blockchain technology and existing systems is relatively high. For any innovation, existing institutions must ensure that it can not only create economic benefits, but also comply with regulatory requirements and connect with traditional infrastructure. Especially when deploying a new basic system, the cost of time, manpower, and material resources is very large, and the resistance encountered within existing traditional organizations is also not small. Of course, the existence of problems cannot hinder the development of blockchain. The proposal and in-depth research of technologies such as simple payment verification, side chains, and lightning network protocols have provided solutions to the above problems.Got the idea.

9. Is blockchain a pyramid scheme?

Blockchain is just an underlying Internet technology and has nothing to do with pyramid schemes. Because many people don’t understand it, many people pretend to be Illegal fund-raising using the slogan of blockchain

10. Is blockchain digital currency reliable?

Only DAPP applications are useful, but currencies are fake. Just one application.
