区块链 伪概念,区块链作假

1. How to remove the fake and preserve the true in the blockchain

The era of barbaric growth is coming, which is both an opportunity and a challenge for the blockchain.
In recent years, blockchain has gradually developed into a hot topic. Especially in 2018, which has just entered, the concept of "blockchain" has appeared frequently in the business world. So what exactly is blockchain? Why is Liang Shiqiao, an entrepreneur and capitalist, so concerned?
Previously, many people thought that there was an equal relationship between blockchain and Bitcoin, but after in-depth understanding, they discovered , this is a wrong idea. To put it bluntly, blockchain is a distributed ledger, and Bitcoin uses blockchain technology to improve itself.
Blockchain is a decentralized technology, just like a country. In this country, the distribution of data information and rights between people is the same, and there is no falsification of data. It is possible and impossible to lose. The two major advantages of sharing mechanism and value exchange are the power of blockchain.
Is blockchain becoming a new trend after Bitcoin?
As early as 2008, Satoshi Nakamoto published an article titled "Bitcoin: A Peer-to-Peer Electronic Cash System" on the forum. The concept of blockchain was first proposed in the article.
However, there have been constant controversies since the emergence of Bitcoin. The loudest opponents are Warren Buffett and Robert Shiller. Buffett, known as the "Stock God", made it clear that Bitcoin "will definitely not have a good outcome in the end." Of course, there are also voices of support. Wall Street tycoon Jamie Dimon believed that Bitcoin was a scam a year ago, but now he has overturned his previous view and believes that blockchain is real. Regardless of the final outcome, the development of Bitcoin has attracted more and more attention in recent years.
In 2013, Bitcoin skyrocketed 100 times from being worthless at the beginning. However, in the next two years, Bitcoin showed a sharp decline again. In 2014, it fell by no less than 70%. In 2015, it fell by more than 20% again. By 2016, Bitcoin entered an upward stage, and by 2017, it was resurrected. This roller coaster development not only brought losses to people, but also attracted more attention to the blockchain.
People love and hate Bitcoin. When Bitcoin becomes popular, as the core foundation and underlying architecture of Bitcoin, blockchain is gradually attracting people's attention. Blockchain is the key to supporting the formation of Bitcoin. The reason why Bitcoin can achieve such results is inseparable from the blockchain. Since every transaction in Bitcoin is recorded in a block-by-block ledger, this ledger is decentralized, and the blockchain serves as the "role" of the Bitcoin ledger. Bitcoin can be said to be the best application of blockchain, bar none.
Some time ago, Xue Manzi acquired this domain name, and in this transaction, Xue Manzi used Bitcoin to complete the transaction. This incident caused quite a stir in the circle. Recently, the frequency of use of Bitcoin in domain name transactions has been increasing, and what caused this phenomenon is capitalExperts attach great importance to blockchain.
Previously, blockchain was only used by Bitcoin, but in recent years, as Bitcoin gradually spreads around the world, blockchain has begun to be applied in various projects, such as Ant Financial, JD.com, Internet and Tencent have gradually begun to apply blockchain technology. The authenticity and non-tampering nature of blockchain makes its application in other projects such as public welfare even more convenient. For example, Ant Financial has applied blockchain technology in "Hearing-impaired Children Regain a New Life", Tencent has launched the "Public Welfare Tracing Chain" and so on. By 2017, blockchain has begun to be widely used and has gradually formed a new trend.
The era of barbaric growth is coming, which is both an opportunity and a challenge for the blockchain
There is this sentence in Dickens's "A Tale of Two Cities": "It was the best of times, it was the worst of times, it was wisdom. This is an era of stupidity. People have all kinds of things in front of them, and people have nothing in front of them; people are going straight to heaven, and people are going straight to hell." Just like the blockchain, if you do it well, you will be the pioneer who participates in the changes of the times. Do it poorly and you will perish.
Today, the blockchain is facing such a situation: the rapidly developing society and the emerging enterprises have brought many possibilities to the blockchain, which has attracted more attention and accelerated the development of the blockchain industry. The enterprise application of blockchain may usher in a new era.
Blockchain can be roughly divided into three types: private chain, alliance chain and public chain. Each blockchain corresponds to different scenario applications. The most critical difference between these blockchains is the degree of decentralization. Limit scope. Blockchain is also widely used due to its distributed recording of data, data cannot be tampered with, and is open and transparent. Different from the transmission of information on the Internet, the blockchain is the transmission of value, which can be said to be an upgrade of the Internet. Based on this, blockchain is considered to be another central technology that is very likely to cause a disruptive revolution after steam engines, electricity, and the Internet.
But the blockchain is not omnipotent:
Firstly, there is delay in the blockchain. Take transactions in Bitcoin as an example. Its effectiveness is affected by network propagation and takes ten minutes to complete. Be informed and recognized;
Secondly, the blockchain itself does not have the two functions of "modify" and "delete", which makes post-processing very troublesome if errors occur when recording data.
In addition to its own limitations, in the face of the complex enterprise market, blockchain, which has gradually become the new darling of the market, has also led to a series of "accidents" such as "coin speculation" and "pseudo-blockchain". .
In September last year, the country had banned the trading of virtual currencies such as Bitcoin and ICO, but the strong money-making effect has brought the currency speculation boom back to people's attention. First, Xunlei launched Wankecoin (now called LinkToken) in October, then Renren released the blockchain project "Renrenfang" and the token RRcoin, and Kodak launched Kodak Coin. Many companies have entered the blockchain development industry. currency, which makes the phenomenon of "coin speculation" sweep across again.
Currently, there are noThere is a lack of money-making projects, and companies are mixed in the blockchain application market. It is difficult for investors to distinguish the pros and cons of projects, and there are even situations where bad coins drive out good coins. In the market, "processing" of public data has become a social norm. For example, in order to attract more consumers and capitalists, companies will modify the data they publish accordingly to attract users to choose and Corporate investment.
In addition, some companies are trying to make money in the name of blockchain. After seeing the benefits brought by blockchain, some companies rushed to enter the market before they understood the operation of blockchain in order to be the first to enter this trend and obtain high profits; some even used blockchain gimmicks to do so. Make money wantonly and retreat quickly after obtaining high profits. This blind application of blockchain has caused some companies that really want to apply and develop blockchain to gradually withdraw from the market, while some companies that mainly focus on making money are still active in the market, which has greatly affected the development of blockchain. normal development trajectory.
Although the blockchain has the core technology to create new trends, because it is still in its infancy and is not mature enough in all aspects, it will still bring about various problems such as "coin speculation", which have become obstacles to the blockchain stumbling blocks to chain development.
Will the increase in entrants accelerate the bursting of the blockchain bubble?
Relevant data shows that from November 2015 to December 2017, the growth rate of blockchain-related occupations reached 631%. However, among this huge data, there are some companies that join the blockchain ranks with the mentality of “getting a quick buck and leaving”, disrupting the normal development of blockchain in the market and further promoting the bursting of the blockchain bubble. 's appearance.
Different from previous years, blockchain has developed very well in recent years, and its application scope has expanded to various fields such as finance, education, government, cloud computing, medical care, and insurance. As the number of entrants gradually increased, many irrationalities appeared in blockchain applications, causing batches of contestants to withdraw.
Recently, a WeChat group called "Blockchain without Sleep at Three O'Clock" has aroused heated discussion. In this group, some well-known people from the industry gathered to talk about blockchain and Bitcoin day and night. Have an in-depth discussion. Among this group of people, blockchain has basically become their “belief”. It seems that if you don’t understand blockchain, you will be eliminated by the times. This kind of blindly following the trend reflects not only people's anxiety about the development of the times, but also the market's strong demand for blockchain. Furthermore, the recent popularity of blockchain concept stocks has triggered more and more investors to enter the blockchain market, causing the blockchain market to expand rapidly and create bubbles.
Furthermore, since the blockchain is still in its infancy, there are still many aspects that need to be improved. At this time, it is tentative for companies and investors to enter the blockchain. Blockchain, a technology with revolutionary significance for the times, still needs to be gradually developed. Moving forward rashly will only push the blockchain that is originally on the right track further.
With regard to the understanding of blockchain development, Gartner consulting firm has previously analyzed relevant aspects: aNew technologies basically go through five stages, namely the budding stage, the popular expansion stage, the bubble bursting stage, the upward recovery stage, and the mature stage. According to Gartner's analysis in 2016, blockchain is already in a period of inflated expectations. At this time, it is in a period when the bubble is about to burst, and it will take 5 to 10 years before blockchain reaches maturity. .
Will blockchain become the key to the era of change?
2017 can be said to be the year of the explosion of blockchain, with various capitals getting involved in blockchain. Although it has brought many problems to the market, the role of blockchain in market development cannot be ignored. Recently, "Three Questions about Blockchain (Economic Hotspots)", "Seizing the Opportunity of Blockchain", and "Being a Leader in the Digital Economy" published in the "People's Daily" clearly stated the impact of blockchain on various fields of the market. important role.
Issues such as delay, "pseudo-blockchain", and "coin speculation" will further attract people's attention after the blockchain bubble bursts, and more standardized market development will occur. Today, blockchain is still in its infancy. As more and more entrants enter the industry, a blockchain bubble is inevitable in the future. But after the bubble, blockchain will bring a disruptive experience to the market and usher in a new era.
Blockchain itself emphasizes "decentralization". In order to meet the ever-changing real needs, blockchain is upgrading to "multi-centering", which will completely break the data "island" and achieve comprehensive interconnection of information. situation. It can strengthen the trust security system, improve transaction efficiency, and meet the application needs of the increasingly developing era.
In short, the explosion of blockchain is inevitable. Its decentralized nature avoids the monopoly of Internet giants and brings development opportunities to many entrepreneurs and investors. But at the same time, based on blockchain, it can reduce transportation costs, is open and transparent, cannot be tampered with, has strong permeability and other properties, and is more convenient for market management. In the future business world, there will be a blockchain era that "removes fakes and preserves authenticity" .

2. What is the concept of blockchain? Is blockchain a scam? The most complete explanation of blockchain

What is the concept of blockchain?

On October 25, 2019, the country advocated the development of blockchain. Overnight, the blockchain concept became popular.

However, many people are hearing about blockchain for the first time.

So, what is blockchain?

Let’s take a look at it from an academic perspective:

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transactions. information, used to verify the validity of its information (anti-counterfeiting) and generate the next zonepiece.

In fact, blockchain is essentially a decentralized database.

Is blockchain the same as Bitcoin? Blockchain is not Bitcoin. The first application of blockchain is Bitcoin.

What are the characteristics of blockchain? Now let’s take a look at several characteristics of the blockchain:

1. Decentralization:

The most important feature of the blockchain is decentralization, and the blockchain system is different Based on a centralized database, it is not controlled by any person or entity. Through distributed storage, data is completely copied and distributed on multiple computers, and each node realizes information self-verification, transmission and management.

2. Non-tamperability:

The blockchain system also has the characteristics of non-tamperability. In the blockchain system, each node is the center and no information can be changed, not even the administrator can modify this information. The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. This situation is basically impossible, thus eliminating the possibility of fraud.

3. Publicity:

In a blockchain system, all nodes in the network can easily access information. The foundation of blockchain technology is open source. In addition to private information being encrypted, blockchain data is open to everyone. Anyone can query blockchain data and develop related applications through public interfaces, so the entire system information is highly transparent. .

4. Independence:

Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so there is no need for a third party whether in transaction or exchange of funds. of approval.

Based on consensus specifications and protocols, the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without any human intervention.

Let’s assume an environment: 6 people live in dormitory 188 of the university

There is a ledger in the dormitory for Xiao Li, who is good at calculation, to keep accounts.

In the beginning, when the dormitory sold paper boxes or bought some public items, Xiao Li would record them in the ledger. If Xiao Li wanted to enrich himself and made false accounts, there would be less money in the account books, but no one would know.

After all, there is already a general ledger room, who would have nothing to do to keep track of the ledgers?

However, one day, because Xiao Li took more, there were obvious errors in the account book. Now, he could no longer hide it, so Xiao Li had to admit his mistake and make up the money.

So, thisHow to solve this problem?

If blockchain is used to solve the problem:

Everyone in the dormitory takes out a ledger, and every time a transaction occurs, everyone records it in their own ledger. , such problems will not arise, because everyone is keeping accounts and can see the transaction records and final results on the ledger.

Xiao Li can’t change, you can’t change, and neither can your lower bunk. No one can change it.

This is because the previous accounting model was a centralized accounting model, and the current accounting model is a decentralized accounting model, where everyone is the center and everyone is the accountant.

If someone wants to change it, it will obviously be ineffective if they only change the data on their own account book, unless they bribe three people.

So, is blockchain a scam?

With the emergence of the great benefits of blockchain, in a short period of time, the prices of blockchain-related assets have soared, and ordinary investors are becoming more and more interested in blockchain. And criminals have also taken aim at this. There are some criminals who wear the gorgeous cloak of "blockchain" and use the blockchain to commit fraud or issue digital currencies without permission, leading many people to think that the blockchain is a scam.

But in fact, it is not. Blockchain is just a technology. If it can be used well, it will benefit the public and promote the development of the industry.

In particular, the application of blockchain is very wide and can be applied to almost everything of value to human beings.

Medical field: For example, when you go to the hospital for medical treatment, you can directly check the previous medical treatment in your own database, which greatly saves medical resources and saves medical expenses for repeated examinations.

Food traceability: Do you know where the food on your table comes from? Which logistics team is transporting it? This information can be tracked using blockchain. It can provide us with a single source of truth.

Supply chain application: For example, when we buy a product on a certain product, it leaves the factory, goes to the distributor for logistics turnover, goes to the seller's store warehouse, and then reaches the consumer's hands. During these processes, if something goes wrong, only you will know about it, and others, especially consumers, will not.

Well, this is where I introduce you to the relevant knowledge about the concept of blockchain. I hope it can be helpful to you.

3. How to make money with blockchain? Is it 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 Only by cultivating it step by step in a down-to-earth manner can it gradually mature. Technology is neutral, but it is human nature that determines the direction and outcome of technology. How will blockchain and digital currency 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 light-asset, high-growth 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 the past business practice, banks often neither fully understand the true market value of mortgages and pledges, nor can they well judge the impact of the company's operations in warehousing and exiting on the market value of the 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. Authenticity and traceability are fully guaranteed, and banks can technically prevent Enterprises and warehousing institutions fabricate warehouse receipts and inconsistencies between warehouse receipts and warehouse entry and exit information to ensure that post-loan management is effective. In addition, the borrowing enterprise’sInformation such as factory building and office building leasing 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 it true that overseas claims that blockchain can combat fake news

On January 27, 2018, Western media reported that the gradually popular cryptocurrency payment, Instant and direct payments for purchases of works and content, as well as public records of personal reputation data, are some of the impacts that blockchain technology will bring to the media industry. That's what a new report predicts.

Blockchain technology can be used to add digital watermarks containing time, author and other information to news works, and reading permissions can be set according to different content. Soon there will be "well-known brands" in the field of blockchain technology applications, and they will create various blockchain applications that interest people, and one of the future tasks of media practitioners is to "identify the surrounding blockchain technology applications." waste generated”, so it is necessary for them to understand blockchain technology.

5. How is the anti-counterfeiting traceability application of blockchain implemented?

The three major characteristics of blockchain are well known, which are decentralization, openness and transparency, and non-tamperability. . The non-tamperable feature enables blockchain to be used in many places. Such as product traceability, anti-counterfeiting, privacy protection, etc.

Because the production process it traces is all uploaded manually, so even if the data cannot be tampered with, the authenticity of the data cannot be guaranteed, and it still cannot be Solve substantive issues.

In general, although blockchain has brought great benefits, it is not perfect after all. However, blockchain technology has advanced the development of the times, and I believe its future is worth looking forward to.

6. What is blockchain anti-counterfeiting technology?

Blockchain anti-counterfeiting technology is a new type of anti-counterfeiting technology used to solve the problem of counterfeiting and shoddy products that appear in the circulation process of goods. . This technology uses a distributed ledger to record and trace the entire process of production, circulation, and sales of goods, and stores the records on the blockchain. Due to the decentralization, non-tampering, and transparency of the blockchain, the authenticity and credibility of the records are guaranteed.
The application of blockchain anti-counterfeiting technology can effectively prevent the circulation of counterfeit and shoddy goods, protect the rights and interests of consumers, and promote the improvement of product quality and the healthy development of the industry. In the fields of food, medicine, luxury goods and other fields, blockchain anti-counterfeiting technology has been widely used. By scanning the Hupin QR code on the product, consumers can check the production, circulation, sales and other information of the product to ensure that they are purchasing authentic products.
At the same time, blockchain anti-counterfeiting technology can also improve the transparency and efficiency of the supply chain. Traditional supply chain management has problems such as information asymmetry and lack of trust, making it difficult to manage the information flow and capital flow of the supply chain. Blockchain anti-counterfeiting technology can solve these problems by recording and tracing the completeness of goods.process, realizing the visualization, traceability and controllability of the slip equipment supply chain, improving the transparency and efficiency of the supply chain, and reducing management costs and risks.
In short, blockchain anti-counterfeiting technology is an innovative anti-counterfeiting technology that can effectively prevent the circulation of counterfeit and shoddy goods, protect the rights and interests of consumers, promote the improvement of product quality and the healthy development of the industry, and can also improve supply. chain transparency and efficiency, contributing to the sustainable development of society.

7. Is blockchain a lie?

"Blockchain" is an important concept in the new era. It is essentially a centralized database and a digital database. The underlying technology such as 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.

8. What advantages does the application of blockchain technology have in anti-counterfeiting and traceability of goods?

In the early days of the "blockchain era", people's understanding of blockchain was limited to numbers. Currency and currency speculation operations. With the development of technology, people realize that applying blockchain technology to industries and promoting the economic development of the industry is its true value. Blockchain traceability and anti-counterfeiting is considered to be one of the most promising areas for blockchain implementation, and it is also one of the first areas where giants compete for the implementation of blockchain application technology. It can be said that whoever can launch the first implementation project will be one step ahead in the industry.
With the help of blockchain technology, commodity raw materials will be flownBy integrating the information on the process, production process, commodity circulation process, and marketing process and writing it into the blockchain, we can realize one-item, one-code, full-process authenticity traceability. Blockchain technology is used to digitize the information of participants in different commodity circulation and store it in the blockchain. These include origins, manufacturers, distributors, retailers, brands and consumers. Make each participant's information viewable in the blockchain.
With the help of blockchain technology, the information of all aspects of the goods from production to warehousing is integrated and written into the blockchain. Each piece of information has an independent and special blockchain ID, accompanied by the digital signature and digital signature of the goods. Timestamps provide users with good underlying data support and product quality control.
At the consumer level, through terminal traceability QR codes and open and transparent blockchain technology support, users can easily check the authenticity of products, cultivate users' awareness of authenticity, and enhance brand value.
Due to the complex and difficult-to-verify transaction content and the temptation of high profits, counterfeiting and selling of counterfeit products are frequently prohibited in the market. This not only affects the shopping experience of consumers, but also damages the brand image of merchants. For merchants and consumers, it is urgent to establish a credible anti-counterfeiting traceability system.
All commodity transactions in the entire market must be supported by a trustworthy anti-counterfeiting traceability mechanism. In this way, we can better ensure the quality of the company's own products and improve consumers' shopping experience.

9. Is blockchain a scam?

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 heavier and 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. The current blockchain system, especially the financial blockchain system, has the problem of long data confirmation time. 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 based on the rate of generating one block every 10 minutes, 144 blocks can be generated every day, which can accommodate 576,000 transactions. Divided by the number of seconds per day, 86,400, the Bitcoin areaThe blockchain can process up to 6.67 transactions per second. 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. The reason why the Bitcoin blockchain payment network The reason why it has grown to be worth billions of dollars today lies in its decentralization. 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 chain, and lightning network protocols have provided ideas for solving the above problems.
Legal basis: "Criminal Law"
Article 266 [Crime of Fraud] Whoever defrauds public or private property, and the amount is relatively large, shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or surveillance, and shall be concurrently or solely punished fine; if the amount is huge or there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years, and shall also be fined; if the amount is particularly huge or there are other particularly serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than ten years or life imprisonment and shall also be fined or Confiscation of property. If this law provides otherwise, the provisions shall prevail.
