A. Is blockchain a lie?

China’s blockchain development is uneven and growing wildly. As of August this year, the development level of my country’s blockchain industry ranks first in the world. It is at the forefront, with the total number of enterprises ranking 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 routine: high rebates for currency speculation

Promotional rhetoric: "Virtual asset financial innovation"

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

B. Is the so-called blockchain real?

This kind It seems unreliable. 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 algorithm. Blockchain is essentially a decentralized database.
For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all your best friends, classmates, Colleagues, as well as various groups and circles of friends, make it impossible for him to deny it anymore. This is called blockchain.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.

C. What does mchain do?

Mchain is a blockchain virtual currency.

Mchain, like Bitcoin and Ethereum, is an encrypted digital currency developed based on blockchain technology. More than 2,000 transactions worldwideTherefore, Mchain is currently listed on three of the international exchanges, and can achieve 24-hour uninterrupted trading in the exchanges.

MChain’s Chinese name is Miner’s Classic Coin, referred to as M Chain. MChain was developed by the top blockchain team in the United States, and the block confirmation speed has been greatly improved.

M Chain is issued on the public chain of the blockchain. The tokens follow the digital currency standards. The total circulation is 21,000,000. There will never be additional issuance. The initial release of 6.3 million tokens is invested by the mines of the M Chain community. Jointly held by creators and community participant founders, the last 14.7 million coins were mined by miners, and all were mined in a total of 20 years.

(3) Extended reading on whether m-chain blockchain is true or false

Blockchain currency characteristics:

1 , decentralization. Due to the use of distributed computing and storage, there is no centralized hardware or management organization in the system. The rights and obligations of any node are equal. The data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.

2. Openness. The system is open. In addition to the encryption of private information of all parties to the transaction, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface, so the entire system information is highly transparent. .

3. Autonomy. The blockchain adopts consensus-based norms and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trustless environment, changing trust in "people" to trust in "people". Machine trust, any human intervention has no effect.

4. Information cannot be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node are invalid, so the data in the blockchain is stable. Extremely high performance and reliability.

5. Anonymity. Since the exchange between nodes follows a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to disclose its identity to make the other party trust itself. Very helpful for credit accumulation.

D. Is the blockchain investment platform a scam?

Blockchain investment itself is not a scam, but its price formation mechanism is opaque and can easily cause huge losses to investors. At the same time, it lacks Regulation 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 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 people's democratic dictatorship and overthrowThe socialist system undermines social order and economic order, infringes upon state-owned property or property collectively owned by the working people, infringes on citizens' private property, infringes on citizens' personal rights, democratic rights and other rights, and other behaviors that endanger society, in accordance with the law. Anyone who should be punished is a crime, but if the circumstances are obviously minor and the harm is not great, it is not considered a crime.

E. Is the blockchain a lie?

"Blockchain" is an important concept in the new era. It is essentially a centralized database and a digital 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.

F. 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 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 a lot of blockchain scams, and we also need to improveBe vigilant to avoid being deceived and causing unnecessary financial 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, 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".

G. What is Mchain? Comprehensive introduction

Mchain comparisonBitcoin and Ethereum are both encrypted digital currencies developed based on blockchain technology.

MChain’s Chinese name is Miner’s Classic Coin, referred to as M Chain. MChain was developed by the top blockchain team in the United States. The block confirmation speed has been greatly improved, and it is the first choice for existing anonymous transaction currencies! The M chain is issued on the public chain of the blockchain. The tokens follow the digital currency standards. The total issuance is 21,000,000 and will never be issued. The initial release is 6.3 million created by the mine investors and community participants of the M chain community. Jointly held, the last 14.7 million coins were mined by miners, and all were mined in a total of 20 years.

(7) Extended reading on whether the m-chain blockchain is true or false:

In 2008, Satoshi Nakamoto wrote in the "Bitcoin White Paper" He proposed the concept of "blockchain", founded the Bitcoin network in 2009, and developed the first block, the "Genesis Block".

The blockchain shared value system was first imitated by many cryptocurrencies, and improvements were made in proof-of-work and algorithms, such as the use of proof-of-stake and SCrypt algorithms. Subsequently, the blockchain ecosystem continued to evolve around the world, with the emergence of initial coin offerings (ICOs), smart contract blockchain Ethereum, asset tokenized sharing economies with “light ownership, heavy usage rights”, and blockchain countries.

Currently, people are using this shared value system to develop decentralized computer programs (Decentralized applications, Dapp) in all walks of life, and build decentralized autonomous organizations and decentralized autonomous communities around the world. (Decentralized autonomous society, DAS).

H. 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. Still taking the Bitcoin blockchain as an example, everyThe average size of a 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 per Bitcoin block (Source: Block Yuan) In comparison, Paypal’s overall number of transactions in the third quarter of 2013 was 729 million, averaging 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.

I. Is the blockchain a scam?

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