⑴ Is the blockchain a scam?

I can’t say that all of it is a scam, but some of it is indeed a scam

< p>⑵ 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 can we make steady progress. , step by step cultivation can make 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.

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 past business practices, banks often did not fully understand the true nature of mortgages and collateral.The market value cannot well judge the impact of the company's operations in warehousing and exiting on the market value of residual collateral and collateral, and the ability to control new loan types such as warehouse receipt pledge 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, 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".

⑶ Why do many people say that blockchain is a lie?

Blockchain is not a lie, but lies under the guise of blockchain. People's people. In fact, blockchain scams take advantage of people's lack of understanding of the technology, and then scammers rely on a variety of fancy methods to set up scams. Many people only look at the surface when making investments, and are eventually lured into the trap by high profits.

In current society, more and more people are willing to take the risk to invest in order to obtain huge returns, but not everyone can make a profit. After all, there are benefits. There are many people squatting and watching, and they will set traps for people to take the bait.

(3) Blockchain computing power is a scam Extended reading:

Notes

Blockchain is a technology , simply put: this technology is based on new ways of data management such as cryptography. Blockchain technology has broad application prospects because of its advantages such as decentralization, non-tampering, full traceability, and traceability. Issuing coins is an act derived from blockchain technology. At present, the vast majority of blockchain applications that focus on issuing and speculating coins are suspected of illegal fund-raising.

Blockchain technology is still in its early stages of development, and its application is also difficult to implement. If you rely solely on a white paper to claim that there is an application, it is an act of deception in itself.

⑷ Is blockchain a lie?

"Blockchain" is an important concept in the new era. It is essentially a centralized database and a digital currency. underlying technologies. 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 applications around people will also form. With continuous improvement, I believe 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.

⑸ Is the blockchain technology a lie? Is it actually related to our lives?

How can something useful be useless

In recent years , more and more people regard blockchain technology as one of the most promising new technologies in the future. Right now, there is a lot of talk about how cryptocurrencies and blockchain will change the world economy. Although the future of cryptocurrencies is unpredictable, the unshakable status of blockchain may continue to lead the development of the industry in the future. In fact, blockchain has changed not only the world economy, but even the daily lives of ordinary people have been greatly changed by its influence. The emergence of blockchain technology itself is an innovative process. Anyone who understands blockchain technology should know that blockchain is a database that can collaborate on a large scale. It allows many different subjects to collaborate to complete a task without trusting each other. This is the essence of blockchain.

Since this year, there have been numerous cases about blockchain technology supporting the resumption of work and production of small and medium-sized enterprises.

⑹ Is blockchain a scam?

Blockchain technology itself It 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 users use the Bitcoin Core client to synchronize data, they may not be able to complete the synchronization for three days and three nights.In addition, the amount of data in the blockchain 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 blockchain can process a maximum of 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 a Bitcoin block (Source: Block Yuan) In comparison, Paypal's overall transaction count 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 infrastructure system, the costThe time, manpower, and material costs are very high, and the resistance encountered within existing traditional institutions 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.

⑺ 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.

⑻ Is the blockchain investment platform a scam?

Blockchain investment itself is not a scam, but its price formation mechanism is opaque, which can easily cause huge losses to investors and lacks supervision. , and therefore may become a scam. If investors are defrauded due to blockchain investment, they can defend their rights against the exchange and the project party. Any behavior that constitutes fraud or other crimes should be reported promptly, and the judicial authorities will investigate the corresponding criminal liability.
[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 sentenced 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. However, if the circumstances are obvious and minor and the harm is not great, they are not considered crimes.

⑼ Is blockchain a lie?

The development of China’s blockchain is uneven and growing wildly. 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 more than 32,000 companies with the word “blockchain” or whose operations involve 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"!

Scammer's routine:

Elementary routine: Use big words to make big profits

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

< p>The essence of the scam: Using so-called "projects" that claim high returns in professional terms to 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 routines:High rebates for currency speculation

Promotional rhetoric: "Virtual asset financial innovation"

The essence of the scam: illegal pyramid schemes (such as various "digital currency" investment projects)

⑽ Why are domestic blockchains said to be a lie

Blockchain unexpectedly ushered in 2018 With the recent outbreak, the world is suddenly filled with the dream of "getting rich overnight" and the "copper smell" of various virtual currencies. Many people have plunged into the "sugar-coating" wrapped in blockchain. Will they realize their dream of getting rich in the huge bubble wave, or will they be treated like "leeks" and be cut off and bankrupt?

At this juncture, some people in the industry pointed out that "blockchain is a good thing, but the current domestic blockchain is all deceptive." Such people may have been "robbed" in the currency circle, and use these words as a declaration of their poverty. He may also be a business leader in the blockchain circle. After reviewing the situation, he can see the various shortcomings of the current development of the blockchain and draw a comprehensive analysis and conclusion.

No matter who they are, this statement must come from the understanding of the current mixed status of the currency circle and the dim prospects of blockchain technology, and this is not difficult to understand. Binance and Huobi Pro, international large-scale digital asset exchanges, have repeatedly encountered hacker attacks, resulting in the loss of user assets. The protection of website security mechanisms and the maintenance of user information and data are extremely unsatisfactory.

People who have suffered losses in the currency circle have turned their attention to the chain circle again, but what disappoints users again is that although the chain circle has great prospects, due to immature technology, the blockchain in all walks of life The chain layout is still in the conceptual stage and it is difficult to take substantive actions. Not only that, even the blockchain media, which is based on fairness and facts, has been exposed to pay to recommend coins to induce investors and promote ICO in disguise in the name of "private placement". In fact, it is an important service for "cutting leeks" tool.

Recently, the "blockchain+Tibetan tea" fund -raising fraud case of a blockchain company in Shenzhen has made the chain circles cool more, and the "world's first digital currency" is about to issue "the world's first original digital currency". The signboard defrauded more than 3,000 investors out of 307 million. However, blockchain companies of this scale and approach are emerging one after another, and it is difficult to distinguish the true from the false.

However, we admit that there are indeed deficiencies in the current domestic blockchain development, but can we generalize and label blockchain companies as "false"?

We should admit that every stage of development of emerging things is bumpy, and even criticized repeatedly. Just like the Internet 20 years ago, how many people could have predicted its earth-shaking development at that time? The same goes for blockchain.

Moreover, at present, domestic Internet giants such as JD.com, Tencent, Ali, etc. from all points such as financial trade, entertainment, leisure, logistics, and medical treatment; Blockchain has made breakthroughs in industries such as media and games one by one; the country has also introduced blockchain technology in strictly regulated industries such as energy and electricity; there are also Leou’s blockchain tourism layout and Ant Financial’s blockchain in Xiongan New Area Technical housing rental cooperation, etc. It can be seen from this that the blockchain layout is not a solo effort of unknown companies. Each has strong support from Internet giants and the government. Amid the collective excitement, how can the blockchain “scam” gain confidence?

Although domestic blockchain companies are still in their infancy in terms of technology and application, this does not negate the blockchain itself and the overall situation of domestic blockchain. As the People’s Daily said, “Blockchain has an unprecedentedly bright future.”
