One article to understand the Internet blockchain

One article to understand the Internet blockchain, you need to understand the blocks In order to understand the blockchain, we have to study the brief history of the technological development of the blockchain starting from the birth of the Internet, discover the motivations for the emergence of the blockchain, and infer the future of the blockchain. Let’s understand the Internet blockchain in one article.

Understand the Internet blockchain in one article 1

The originator of blockchain is mahjong, and the earliest blockchain was invented by the Chinese! The blockchain is just like Mahjong, except that Mahjong has fewer blocks. Mahjong only has 136 blocks. The rules of Mahjong vary from place to place and can be regarded as a hard fork of Bitcoin.

As the oldest blockchain project, Mahjong has a group of four miners. The first one to dig out the 13 correct hash values ​​will get the accounting rights and rewards. It adopts the method of being willing to admit defeat and not cheating. Thousands of consensus mechanisms!

Mahjong is decentralized, everyone can be the banker, and it is completely peer-to-peer.

Mining pool = commission from the boss of the chess and card room.

It cannot be tampered with, because convincing the other three people requires too much computing power and physical strength.

A typical value Internet. The value in my pocket didn't last eight rounds before it went into their pockets.

The Chinese are basically good at playing mahjong. In terms of blockchain, they produce 70% to 80% of the world’s mining machines and have the most computing power in the world, accounting for about 77% of the computing power.

Mahjong is actually the earliest blockchain project:

1. A group of four miners. The miner who first collides with the correct hash value of 13 numbers can obtain the accounting rights. and get rewarded.

2. It cannot be tampered with. Because convincing the other three people requires too much computing power and physical strength.

3. Typical value Internet. The valuable digital currency www.gendan5.com/digitalcurrency/btc.html in my pocket ran into their pockets after eight rounds.

4. Decentralization, everyone can be a banker, it is completely peer-to-peer.

5. UTXO, unspent transaction expenses.

There is another blockchain method of credit, assuming that everyone has no cash

Let’s take a closer look. When everyone reaches a consensus, we see There is no intermediary or third party to judge whether C wins, and the rewards given to C do not need to be transferred to C through a third party. They are all direct peer-to-peer transactions. This process is decentralized, and players (miners) record their own records. After recording the results of the first game, B Dahu drew thirteen pieces, and B got Jia Dongfeng. After the record was completed, a complete block was generated, but remember, this was only the first game. In the entire blockchain On, this is just a node. After the 8 rounds mentioned at the beginning, that isIt is 8 nodes (blocks). The 8 blocks are connected together to form a complete ledger. This is the blockchain. Because everyone has one of this ledger, it is a distributed ledger. The purpose is to prevent someone from tampering with the record. At the end of the game, it is clear who wins and who loses.

Four men (A, B, C, and D) got together to play mahjong for money. None of them brought any cash, so they asked a beautiful woman (centralized) to keep a book and record who won how much money in each round. , Who lost how much? At the end of the day, everyone uses Alipay or WeChat to pay and settle the ledger. However, if this beauty made a mistake in accounting or was bribed by one of the four people in advance to make a mistake on purpose, there is no guarantee that the outcome of this game will be fair, just, and reasonable. ,dont you agree? then what should we do? If you "play mahjong", you can use "blockchain" as the game rules and adapt it as follows:

Four men (A, B, C and D) got together to play mahjong for money. No one brought any cash. B said Let the beauty she brought keep accounts. A said that none of us knew this beauty, so the four of them, A, B, C, and D, agreed that everyone would keep accounts at the same time (decentralized) on their mobile phones (blockchain nodes) for each game. ), after finally playing mahjong and paying with electronic money directly on the mobile phone, everyone checked the accounting results. The accounting results should have been the same.

Assume that the original result is the account recorded on A’s mobile phone: B owes A 10 yuan. However, the record on B's mobile phone shows that there is no debt, but the other two people (C and D) have the same accounting as A, so the settlement is still based on the majority rule. In addition, everyone has a bad impression of B's ​​integrity. Next The first time I play mahjong, I won’t take B to play with me.

Unless B bribes two people (C and D) in advance to deliberately cheat, but the cost of B bribes them is 100,000 yuan (10,000 times the default of 10 yuan), then in common sense, B only You can choose to give up because the cost of counterfeiting is too high.

Assume that even if B is secretly willing to pay a high price of 100,000 yuan to buy C and D to do this silly cat transaction with huge losses during the card game, the rules of the blockchain are to keep accounts based on timestamps. Yes, it turns out that B owed A 10 yuan when debiting the account at 1 p.m., that is, when C and D changed the account at 3 p.m., time is irreversible and they can only record 3 p.m., which does not comply with the rules of the game. .

In fact, in 2017 the blogger has developed a set of Mahjong coins

China’s earliest blockchain project: a group of four miners, first starting from 148 random numbers The miner who collides with the correct hash value of 14 numbers can obtain an accounting right incentive. Since distributed accounting requires the consensus of several other miners, each accounting transaction takes about ten minutes.

Understanding the Internet Blockchain in One Article 2

1. Before the birth of Bitcoin, 5 Internet technologies that will have a significant impact on the future of the blockchain

In 1969, the Internet was born in the United States. Since then, the Internet has expanded from four research institutions in the United States to the entire planet. In terms of application, from the earliest military andScientific research extends to all aspects of human life. In the nearly 50 years since the birth of the Internet, five technologies have been of particularly great significance to the future development of blockchain.

1. The TCP/IP protocol born in 1974: determines the position of blockchain in the Internet technology ecosystem

In 1974, the most critical step in the development of the Internet was taken by The TCP/IP protocol, the core communication technology of the Internet jointly developed by American scientists Vinton Cerf and Robert Kahn, was officially launched.

This protocol enables the transmission of information between different computers and even different types of networks. All computers connected to the network can communicate and interact as long as they comply with this protocol.

In layman's terms, Internet data can travel tens of thousands of kilometers to reach the computer users who need it. This is mainly because the Internet world has formed a unified information dissemination mechanism. That is to say, Internet devices follow a unified law-TCP/IP protocol when disseminating information.

Understanding the TCP/IP protocol is of great significance to mastering the Internet and blockchain. After the invention of TCP/IP in 1974, the entire Internet was between the underlying hardware devices, the intermediate network protocols and the network Addresses have always been relatively stable, but an endless stream of innovative applications are emerging at the top application layer, including news, e-commerce, social networks, QQ, WeChat, and blockchain technology.

In other words, in the technical ecology of the Internet, blockchain is a new technology at the top layer of the Internet - the application layer. Its emergence, operation and development have not affected the underlying infrastructure and communication protocols of the Internet. , is still one of the many software technologies that operates according to the TCP/IP protocol.

2. Cisco router technology born in 1984: an imitation of blockchain technology

In December 1984, Cisco was established in the United States. The founder was a professor from Stanford University. A couple, Leonard Posak, director of the computer center, and Sandy Lerner, director of the business school's computer center, designed a networking device called a "multiprotocol router" that was placed on the Internet's communication lines to help data Get from one end of the Internet to the other thousands of kilometers away accurately and quickly.

In the entire Internet hardware layer, tens of millions of routers are busy working, directing the transmission of Internet information. An important function of Cisco routers is that each router saves a complete Internet device address table. Once something happens Changes will be synchronized to tens of millions of other routers (theoretically), ensuring that each router can calculate the shortest and fastest path.

When you see the operation process of the router, you will feel very familiar. That is the important feature of the blockchain later. The significance of understanding the router lies in the important features of the blockchain. It has been implemented on the router in 1984. For the router, even if the node device is damaged or attacked by hackers,, and will not affect the transmission of information on the entire Internet.

3. The B/S (C/S) architecture that was born with the World Wide Web: the opponent of the blockchain and the target of attempted subversion

The World Wide Web is referred to as the Web and is divided into Web clients and server. All updated information is only modified on the Web server. Thousands, tens of thousands, or even tens of millions of other client computers do not retain the information and only obtain the information data when accessing the server. This structure is also often referred to as the Internet B/S architecture is a centralized architecture. This architecture is also the most important architecture of the current Internet. Internet giants such as Google, Facebook, Tencent, Alibaba, and Amazon have all adopted this architecture.

Understanding the B/S architecture will be of great significance to the subsequent understanding of blockchain technology. The B/S architecture is that data is only stored in the central server, and all other computers obtain information from the server. Blockchain technology has tens of millions of computers without a center, and all data will be synchronized to all computers. This is the core of blockchain technology.

4. Peer-to-Peer Network (P2P): Blockchain The father of the chain and its technical basis

Peer-to-peer network P2P is another Internet infrastructure corresponding to C/S (B/S). Its characteristic is that multiple computers connected to each other are connected to each other. In a peer-to-peer position, there is no distinction between master and slave. A computer can be used as a server, setting shared resources for use by other computers in the network, and as a workstation.

Napster is one of the earliest P2P systems, mainly used for music resource sharing. Napster cannot be regarded as a true peer-to-peer network system. On March 14, 2000, a message was posted on the mailing list of the underground hacker site Slashdot in the United States, saying that AOL's Nullsoft department had released Gnutella, an open source Napster clone software.

In the Gnutella distributed peer-to-peer network model, each networked computer is functionally peer, serving as both a client and a server, so Gnutella is called the first true peer-to-peer network model. Network Architecture.

In the past 20 years, some Internet technology giants such as Microsoft and IBM, as well as liberals, hackers, and even criminals who infringe intellectual property rights, have continued to promote the development of peer-to-peer networks. Of course, those on the Internet want to strengthen information sharing. The idealists also put a lot of enthusiasm into peer-to-peer networks. Blockchain is a software application based on a peer-to-peer network architecture. It is a benchmark application for peer-to-peer networks trying to break out from the silence of the past.

5. Hash algorithm: the key to generating Bitcoin and tokens (tokens)

The hash algorithm converts numbers of any length into fixed-length values ​​using a hash function. Algorithms, famous hash functions such as: MD4, MD5, SHS, etc. It is established by the American National Institute of Standards and TechnologyA member of the defined family of cryptographic functions.

This family of algorithms is crucial to the functioning of the entire world. From Internet application stores, emails, anti-virus software, to browsers, etc., all of them are using secure hashing algorithms. It can determine whether Internet users have downloaded what they want, and it can also determine whether Internet users are involved in man-in-the-middle attacks or network attacks. Victim of a phishing attack.

The process of blockchain and its application to generate new coins from Bitcoin or other virtual currencies is to use the function of the hash algorithm to perform operations to obtain numbers that meet the format requirements, and then the blockchain program gives Bitcoin rewards.

Mining, including Bitcoin and tokens, is actually a small mathematical game built with a hash algorithm. However, because of the fierce competition, people all over the world used powerful servers to perform calculations in order to get the rewards first. As a result, many computers on the Internet participated in this little mathematical game, which even consumed more than 40% of the electricity in some countries.

2. The birth and technical core of blockchain

The birth of blockchain should be the most unusual and mysterious invention and technology in the history of human science, because in addition to blockchain, to So far, there is no major invention in the history of modern science whose inventor cannot be found.

On October 31, 2008, Bitcoin founder Satoshi Nakamoto (pseudonym) published a paper on the cryptography mailing group - "Bitcoin: A Peer-to-Peer Electronic Cash System". In this paper, the author claims to have invented a new electronic currency system that is not controlled by governments or institutions. Blockchain technology is the basis for supporting the operation of Bitcoin.

The preprint address of the paper is at http://www.bitcoin.org/bitcoin.pdf. From an academic point of view, this paper is far from a qualified paper. The main body of the article is composed of 8 flow charts. It is composed of corresponding explanatory text, no nouns and terms are defined, and the format of the paper is also very irregular.

In January 2009, Satoshi Nakamoto released an application case of blockchain on the SourceForge website - the open source software of the Bitcoin system. After the release of the open source software, it is said that Satoshi Nakamoto mined approximately 1 million bits. Coin. A week later, Satoshi Nakamoto sent 10 Bitcoins to cryptography expert Hal Finney, which became the first transaction in Bitcoin history. With the booming development of Bitcoin, research on blockchain technology has also begun to show explosive growth.

It is indeed difficult to fully and clearly explain the blockchain to the public. We use Bitcoin as the object to introduce the technical characteristics of the blockchain as simply as possible but in depth.

1. Blockchain is a peer-to-peer network (P2P) software application

As we mentioned before, at the beginning of the 21st century, the Internet formed two major types of applications. Architecture, centralized B/S architecture and non-centered peer-to-peer (P2P) architecture, Alibaba, Sina, AmazonXun, many Internet giants such as the Internet have a centralized B/S architecture. To put it simply, data is placed on giant servers. We ordinary users access the servers of Alibaba, Sina and other websites through mobile phones and personal computers.

Since the beginning of the 21st century, there have been many software applications for freely sharing music, videos, and paper materials. Most of them use a peer-to-peer network (P2P) architecture, that is, there is no central server, everyone's personal computer They are all servers and clients, with equal status. However, this type of application has never become popular. The main reasons are large resource consumption and intellectual copyright issues. Blockchain is a software application in this field.

2. Blockchain is a peer-to-peer network (P2P) software application that synchronizes information across the entire network

Peer-to-peer networks also have many application methods. In many cases, everyone is not required to Each computer keeps the same information. Everyone only stores the information they need, and downloads it to other computers when needed.

However, in order to support Bitcoin financial transactions, the blockchain requires that every transaction that occurs must be written into historical transaction records and change information be sent to all computers with Bitcoin programs installed. Every computer with Bitcoin software installed maintains the latest and complete Bitcoin historical transaction information.

The characteristics of blockchain's network-wide synchronization and network-wide backup are often referred to as blockchain information security, and the source cannot be changed. Although it is still not absolutely safe in practice, when the number of users is very large, it does have certain security advantages in preventing information tampering.

3. Blockchain is a peer-to-peer (P2P) software application that uses a hash algorithm to generate "tokens" to synchronize information across the entire network

Area The first application of the blockchain was the famous Bitcoin. When discussing Bitcoin, a term that is often mentioned is "mining". So what exactly is mining?

The metaphor is that the blockchain program gives the miners (players) 256 coins, numbered 1, 2, 3...256. Each time a Hash operation is performed, it is like tossing a coin. 256 coins are thrown at the same time. After landing, if all the coins with the first 70 numbers happen to be heads. The miner can tell the blockchain program this number, and the blockchain will reward the miner with 50 Bitcoins.

From the perspective of software programs, Bitcoin mining is a mathematical game built using the hash SHA256 function. The blockchain first stipulates a winning mode in this small game: a 256-bit hash number is given, but the last 70 bits of the hash number are all 0, and then the player (miner) continuously enters various numbers. Give the hash SHA256 function and see if you can use this function to get a number with 70 zeros. If you find one, the blockchain program will reward the player with 50 Bitcoins. Actual mining and rewards are more complex, but the above example expresses the core process of mining and obtaining Bitcoin.Procedure.

When Bitcoin was born in 2009, each bounty was 50 Bitcoins. Ten minutes after its birth, the first batch of 50 Bitcoins was generated, and the total currency amount at this time was 50. Subsequently, Bitcoin increased at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty is halved to 25. When the total amount reaches 15.75 million (new output is 5.25 million, which is 50% of 1050), the bounty is further halved to 12.5. According to the design of the Bitcoin program, the total number of Bitcoins is 21 million.

From the above introduction, Bitcoin can be seen as a guessing game based on a peer-to-peer network architecture. The Bitcoin information rewarded for each correct guess will be transmitted to all players and recorded. into each player's history database.

4. Smart contracts, tokens, ICOs and blockchain basic platforms generated by blockchain technology due to the rise of Bitcoin

From the above introduction, Bitcoin technology It is not a new technology falling from the sky, but a clever combination of various original Internet technologies, such as peer-to-peer network architecture, network-wide synchronization of routing, and network security encryption technology. It can be regarded as a combination of innovative algorithm games. .

Because Bitcoin can be exchanged for legal currency, purchased in kind, and made huge profits through appreciation, the whole world is not calm. With the attitude that if you can do it, I can do it, many people have created their own imitation Bitcoin software applications. At the same time, taking advantage of the difficulty for the government to regulate peer-to-peer networks, various altcoins exploded together with Bitcoin. There have been many incidents of fraud and absconding, which have gradually attracted the attention of governments around the world.

Blockchain basic platform: It is still quite technically difficult to create currency using the blockchain technology framework. At this time, basic technology platforms such as Ethereum, the blockchain basic platform, have emerged, making it convenient for ordinary people. Create a "Bitcoin"-like software program, each showing its magical powers, inviting people to join the game to mine coins, speculate on coins, and gain profits from it.

Pass or token: If each "Bitcoin" or "Altcoin" uses a hash algorithm to create a guessing game and generates its own "currency", this "currency" is collectively referred to as " "Certificate" or "Token".

ICO: Since Bitcoin and Ethereum have been exchanged with the legal currencies of various countries, when other new virtual currencies are issued, only Bitcoin and Ethereum are allowed to purchase the new issued coins. This process of issuing coins It’s called ICO. The emergence of ICO has amplified the transaction volume of Bitcoin and Ethereum. At the same time, many ICO projects are completely based on nihilistic projects, resulting in a large number of frequent fraud cases. This further deepens society’s negative understanding of virtual currencies generated by blockchain.

Smart contract: It can be seen as a software function on the blockchain. It is a program that assists various virtual currency transactions on the blockchain. The specific function is like the fund custody of Alipay on Taobao. When a user receives the goods and confirms them on Alipay, the funds are automatically paid to the buyer and owner., smart contracts also assume this intermediary payment function in blockchain applications such as Bitcoin.

3. The historical status and future prospects of blockchain technology in the Internet

1. Where does blockchain stand in Internet technology? It is a new software and architecture at the top level.

We mentioned in the previous introduction to TCP/IP that blockchain, like browsers, QQ, WeChat, online game software, mobile APPs, etc., is a software form of the top layer of the Internet - the application layer. . Its operation still relies on the TCP/IP architecture system to transmit data. But unlike most application layer software, it does not adopt the central software architecture of C/S (B/S). Instead, an unusual peer-to-peer network architecture is adopted. From this point of view, blockchain cannot subvert the Internet infrastructure.

2. Who does blockchain want to subvert? Want to subvert the B/S (C/S) structure of the World Wide Web.

It attempts to subvert the B/S, C/S structure of the World Wide Web, which was born in 1989. Said before. Since 1989, European physicist Tim Berners-Lee invented the World Wide Web and gave up applying for a patent. In the past nearly 30 years, companies including Google, Amazon, Facebook, Alibaba, Internet, Tencent and other companies have used the B/S (C/S) structure of the World Wide Web to grow into Internet giants.

In their headquarters, a powerful central server cluster was established to store massive amounts of data. Hundreds of millions of users obtained the data they needed from the giant servers. This also led to the emergence of cloud computing, and then the Internet giants Open up your unused central server resources to further absorb data from enterprises, governments, and individuals. Centralized Internet giants have an increasing influence on the world, countries, and Internet users.

The goal of blockchain is to try to reduce the influence of Internet giants by distributing data to each Internet user’s computer. It can be seen that the real opponent of blockchain and what it wants to subvert is the 1990 The B/S (C/S) structure born in 2007. But whether it can be subverted depends on its technical advantages and bottlenecks.

3. Technical flaws of blockchain: dilemmas caused by the pursuit of complete equality and freedom

The technical flaws of blockchain first come from its peer-to-peer network architecture. For example For example, Taobao currently has a B/S structure, and massive data is stored in the Taobao server cluster computer room. Hundreds of millions of consumers access the Taobao server website through their browsers to obtain the latest information and historical information.

If blockchain technology is used, hundreds of millions of people will retain a complete Taobao database on their personal computers or mobile phones. Every time a transaction occurs, it will be synchronized to hundreds of millions of other users. This is completely unachievable in reality. The amount of data transferred and stored is too large. It is equivalent to setting up and running hundreds of millions of Taobao websites at the same time.

Therefore, blockchain cannot be applied to projects with large amounts of data, and even smaller website projects cannot use blockchain.It will be difficult. By 2018, Bitcoin had been running for nearly 10 years, and the accumulated transaction data had brought the entire system to collapse.

So the blockchain has adopted many alternative methods, such as establishing relay nodes and lightning nodes. These two concepts can also make people confused. In layman's terms, the blockchain will ask it for The subversive object B/S structure has been studied, and a data server center has been established to become the relay node of the blockchain, which can also be accessed with a browser-like terminal. This is the lightning node of the blockchain.

This change can alleviate the technical shortcomings of the blockchain, but it does make the blockchain what it opposes, centralization. It can be seen that pure blockchain technology has major flaws due to its technical characteristics and cannot be widely used like the World Wide Web. If the technology is upgraded and some parts adopt a B/S (C/S) structure, the blockchain will become centralized. The information node no longer maintains the dream when it was born.

4. Looking at the future prospects of blockchain from the Internet brain model

We know that the Internet generally refers to the Internet that connects computer networks around the world. On this basis The development of a global Internet network covering the whole world is called the Internet, which is a network structure that is interconnected.

Since the birth of the Internet in 1969, humans have innovated in the Internet field from different directions, and there is no unified plan to build the Internet into a structure. When the wheel of time reaches 2017, with the advent of artificial intelligence, With the vigorous development of science and technology such as the Internet of Things, big data, cloud computing, robots, virtual reality, and the industrial Internet, when humans look up to see the giant systems they have created, the model and architecture of the Internet brain have become increasingly clear.

Through nearly 20 years of development, relying on the B/S and C/S structures of the World Wide Web, Tencent QQ, WeChat, Facebook, Weibo, and Twitter Amazon have developed structures similar to neuron networks. Internet devices, especially personal computers and mobile phones, map personal data and functional space on the giant's central server through the software on the device, allowing them to add friends, communicate and transfer information. Internet giants continue to optimize the software versions of hundreds of millions of terminals through software upgrades in central server clusters. In the neurological system, this is a standard central nervous system structure.

The birth of the blockchain provides another neuron model. Instead of uniformly managing neurons in the centralized services of giants, each terminal, including personal computers and personal mobile phones, becomes an independent neuron node. , retaining an independent data space and synchronizing mutual information. In the neurological system, this is a distributed neural structure with no center and multiple neural nodes.

Interestingly, these two different types of neural structures appear in the development of the nervous system. In lower organisms, blockchain-like neural structures have appeared, with multiple ganglia with the same functions, all of which can command body activities and reactions. However, with the evolution of organisms, these ganglia gradually merged.When we evolved into higher organisms, the central nervous system appeared, which contains a large number of neurons for interaction.

4. Judgment on the future status of blockchain in the Internet

1. Understanding of Bitcoin: a guessing game based on peer-to-peer network architecture (P2P), Through clever financial and public opinion operations, it has become a "world currency" that is not subject to government supervision.

2. Understanding of blockchain: a peer-to-peer (P2P) software application that uses hashing algorithms to generate "tokens" to synchronize information across the entire network.

3. Blockchain has specific uses, such as large-scale election voting, large-scale gambling, financial transactions that circumvent government financial supervision, etc. It still has irreplaceable uses.

4. In more cases, blockchain technology will rely on the B/S and C/S structures of the Internet to achieve functional expansion, but overall it is still a supplement to the existing technology of the Internet. Most of the application scenarios currently envisaged by blockchain can be implemented using B/S and C/S structures, with higher efficiency and more mature technology.

5. Whether from the perspective of information transmission efficiency and resource consumption, or from the evolution of the nervous system, blockchain cannot become the mainstream architecture of the Internet, let alone a subversive and revolutionary leader of the future Internet.

6. Of course, Internet giants developed with B/S and C/S structures also have their problems, but these can be gradually solved through commercial and political methods in the future.

Is how to make money with 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 those who respect the law of growth can Only by cultivating it step by step under certain conditions 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 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 provident fund interconnection to help banks understand the social security of shareholders, executives, and ordinary employees of borrowing companies., provident fund and other actual payment status, so as to reasonably evaluate the company's personnel size and operating conditions, and provide sufficient basis for credit and loan 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".

iii How Tencent responds to the blockchain issue

Although Bitcoin has always had mixed reputations, the underlying technology blockchain that supports its development is increasingly recognized and recognized by all walks of life. Pay attention to. At the beginning of 2018, the popularity of blockchain has rapidly escalated again. Not only small start-ups, but also giant companies such as Tencent, Alibaba, Internet, and JD.com have also increased their investment in blockchain.

Tencent’s blockchain applications are in the stage of gradually blooming in many areas. Blockchain technology has been applied in supply chain finance, Tencent Micro Gold, logistics information, and legal evidence storage. , public welfare recruitment and other fields. In addition, Tencent also launched the blockchain open platform BaaS.

Cai Yige also revealed that this year he will promote the combination of blockchain and supply chain finance and launch an open platform for supply chain finance. At the same time, on the ABS platform and virtual digital assets, etc.The field continues to be explored and implemented.

㈣ Why is it said that domestic blockchains are all lies

Blockchain unexpectedly ushered in a big explosion in 2018, and the world was suddenly filled with "get rich overnight" ” dream 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 this statement 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. However, 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 will it be able toTo summarize, label blockchain companies “fake”?

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 “scam” of blockchain 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 unprecedented bright future.”

㈤ What are the financial scams in the blockchain and how to spot them

With the continuous development of social economy, in our real life, we will always encounter various scams. Various problems, especially scams about blockchain fund fraud, make every one of us investors hate this very much. Next, the editor will lead you to take a look at what happens when we encounter blockchain When there are financial scams, how should we detect them and how to prevent these scams.

To sum up, we can clearly know that blockchain funding scams often have these types of scams, so when we find that these types of scams exist, Sometimes, we must not believe it, and in the process of investment, we must invest in regular big brands and big projects, and do not casually believe in the high returns that someone brings to us. This is all Fake.

㈥ What Tencent has done in the blockchain

Ma Huateng: Blockchain, OK; ICO, not OK

At the two sessions, Ma Huateng said blockchain The topic has been very hot recently, and some people even ridiculed that the Internet before blockchain was the "classical Internet." Although blockchain technology is innovative, how to make good use of this technology is another issue.

In Ma Huateng’s view, blockchain technology can be applied in many fields.Especially when it comes to digitally authenticating the uniqueness of physical objects. Just like a document, a ticket, etc. in reality, blockchain technology can be used to ensure that they cannot be copied or tampered with. Compared with traditional IT technologies in the past, blockchain is of epoch-making significance in truly simulating the uniqueness of documents and receipts in real society.

As for doing digital currency ICO, Ma Huateng believes that there are still many risks. He said: "If everyone can use blockchain technology to issue digital currencies at will, it will cause a lot of regulatory issues."

For example, gold was tested during the Spring Festival in 2017 The red envelope project is Tencent’s attempt to use blockchain technology to record users’ digital assets. In terms of public welfare tracing, Tencent also uses blockchain technology to reduce the problem of information asymmetry.

In addition to finance and public welfare, Tencent also reached a cooperation with Intel in September 2017, announcing that the two parties would jointly develop blockchain technology to improve security protection capabilities in Internet of Things scenarios.

㈦ Is blockchain a pyramid scheme? Is blockchain a disguised pyramid scheme?

Blockchain is a new technology and is not a disguised pyramid scheme. It is just claimed by many pyramid schemes to be "blockchain "Chain" actually 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 hype 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 the beginning of this year, with the increased supervision and the cooling of the currency speculation trend, new opportunities have been brought 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 I don’t know much about blockchain or virtual currency, the high amount of investmentThe capital gains made Tang Haiyan full of expectations. 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. .

An investigation by the Shenzhen police found that the company claimed that investors could trade "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", arrested more than ten main suspects, and froze the funds involved in the case There were more than 100 accounts, and more than 300 million yuan of funds involved were seized.

Jinan police said 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 large network under the banner of blockchain.Online marketing case. 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 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, digital exchanges, etc. to endorse the "Air Coin" project platform and create 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.

Currently, 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.

Secondly, blockchain is not omnipotent and there are risks in 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 currency 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.

Thirdly, the popularity of blockchain is 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.

(7) Is Tencent Blockchain going to dig holes? Further reading:

On August 24, 2018, the China Banking and Insurance Regulatory Commission website released an article Risk warning reminds the general public to guard against illegal fund-raising in the name of "virtual currency" and "blockchain".

The original text is as follows:

"Risk Tips on Preventing Illegal Fund-raising in the Name of "Virtual Currency" and "Blockchain""

China Banking and Insurance Regulatory Commission, Central Network The Office of Information Technology, 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 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. Networking and cross-borderization are obvious. Relying on the Internet and chattingTools are used for transactions and online payment tools are used to receive and disburse funds. Risks have a wide scope and spread quickly. Some criminals rent overseas servers to build websites, essentially carry out activities for domestic residents, and remotely control 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.

㈧ Blockchain wallet scams.

What I want to share with you today is a blockchain wallet scam.

At present, various blockchain projects are flying all over the market. Whichever industry is popular will have which chain and which currency!

These blockchain projects are financial investment projects and are different from the blockchain technology advocated in my country’s key development directions. It is a fund package that uses blockchain technology as a bait for packaging, speculation, hype, and money trapping.

Blockchain is a decentralized super ledger that cannot be copied, falsified, or changed. A technology like this is still used in many practical scenarios in banks, insurance, and large companies such as Alibaba and Tencent.

Many so-called blockchain projects do not have any service targets, so just build a blockchain. Who will they serve? Where will they be applied? It is nothing more than creating a concept. Raise the currency price to make money.

I think there are two types of people who understand human nature best in the world, one is psychologists, and the other is liars. In the eyes of these behind-the-scenes bosses and liars, the new technology of blockchain, mixed with virtual currency, is an excellent story framework that can be used to make money with a little processing.

Those mainstream virtual currencies do not have extremely short cycles and collapse at the speed of light like domestic MLM coins or altcoins. Instead, they fall, rise, rise, rise and fall in a long cycle, just like the stock market. . There is a saying in the currency circle that it is harder to keep money than to be a widow

Therefore, those who have the fantasy of getting rich all day long hold in the hands of these seeds that are said to be able to get rich, but they watch them fall every day. It goes up again and again, up and down again. Isn’t it like sitting on pins and needles? How many ordinary people can sit still?

At this time, the blockchain wallet came into being. “As long as you put the money on hand The virtual currency is deposited in my so-and-so wallet, the capital is guaranteed and the income is guaranteed, and it is quite comfortable to get rich while lying down."

There was once a very popular wallet product that claimed to guarantee principal and provide monthly interest rates as high as 10%-30%. The operation is even simpler than P2P. First deposit the virtual currency into the app account, then turn on the "smart dog" brick-moving mode, and then open the wallet every day and watch the assets rise. That is to say, you can make money while lying down.

Moreover, as long as you use the compound interest investment model and recruit people, the annual return is conservatively estimated to be 700%! If you recruit people to level 10, the rate of return will be 1400%! All fools know that it can Get rich!

Haha, this is the brilliance of a trader. One product can clearly arrange the psychology of leeks!

The wallet, to put it nicely, is called "quantitative trading bricks" "In fact, it is just a disguised fund disk. The essence is fixed rebates. In fact, those traders in the past found that consumer rebates are not easy to use, so they started to package them. Seeing that the blockchain is hot now, they used mainstream coins to make an article. I packaged a wallet and said My wallet has high-frequency cash out and high-frequency trading functions. In the past, you used to use money to buy products, or you gave me money directly. You are worried. Now I don’t want money. You use the money to buy Bitcoins. Then put your Bitcoins in my wallet, and I will give you interest every day of the month based on the amount of coins you put.

Well, Bitcoin is money, and you bought your coins with money. In the end, he may shut down the Internet and run away, then take all your coins and go to the transaction himself. All cashed out.

You want his interest, he wants your principal!

The blockchain wallet model is actually a model that uses fixed rebates to attract investors. The difference is that the deposit is virtual currency. The most typical blockchain wallet is the plus wallet,

For example, after you deposit Bitcoin, you will be given a rebate every day. The source of the rebate claims to be intelligent arbitrage as a source of income, and then returns you platform currency, and then transfers the platform currency to international exchanges. Exchange it with a digital currency on the market, and then withdraw money from Huobi to get profits. When you withdraw cash, you will be charged a handling fee. For example, if you withdraw within 28 days, you will be charged a 5% handling fee. If you withdraw after 28 days, you will only be charged a 1% withdrawal handling fee.

It was officially launched on May 1, 2018, and the plus wallet trading platform was launched in October. It collapsed in June 2019. After running for more than a year, this disk package became one of South Korea’s Team operation is actually driven by the Chinese. Six traders have been arrested by the Chinese police. This project has 1 million members participating and the funds involved reach 20 billion yuan.

Judging from the running time, this product has a long existence cycle, which should be beyond the imagination of many people at the beginning. The reasons are:

First, it uses What you invest in is virtual currency, and what you withdraw is also virtual currency. For these mainstream currencies, Leeks have better illusions, thinking that there is still a lot of room for appreciation, and it will be more profitable to keep them. Since it is just a matter of putting it forward, why not continue to put it in the plus wallet to get the profits? To a certain extent, it delays the time of large-scale withdrawals.

Secondly, Plus Wallet spent a lot of money on publicity. One moment it sponsored some blockchain conference, the next it talked about developing new products and launching new systems, and the next it talked about going public. The purpose of this crazy campaign is to exchange time for space.

Let me introduce you to several methods of blockchain wallet in detail:

The first point is that the so-called arbitrage cannot support your subsequent rebate income. .

Because the real income from moving bricks is not a stable income, and it will not be as substantial as he described.

Like the plus wallet, based on the rebate data before the crash, it needs 700 million yuan in rebates every day to continue operating, so this number is astronomical. Obviously there is no way to do smart arbitrage. If you think you can, then you have nothing to do with it. With such high skills in moving bricks, do you still need to rely on rewards to attract people? You can move it yourself, and there are big institutions rushing to invest, so there is nothing to do with you!

The second point is that the money returned by the platform to the people in front is mainly the funds coming in from behind, which is exactly the same as the characteristics of the fixed rebate plate.

If you want a promotion reward system with up to 10 levels, as well as super high rebates, you also have to pay high deposit interest. Therefore, soon the subsequent funds will not be able to keep up with the speed of rebates, and problems will arise in the capital chain. The platform will shut down and runroad.

The third point is that the platform currency exchange channel for Bitcoin can be closed at any time. As for when to close, only the trader can decide, so you are faced with huge risks at any time.

Point 4: It is stipulated that you will be charged a 5% handling fee for withdrawals within 28 days, and you will only be charged a 1% handling fee for withdrawals after 28 days. This purpose is to allow you to extend the withdrawal time as much as possible , he can deposit more funds into the capital pool.

Originally, everyone entered the currency circle because it is a decentralized technology. You store the currency in a real wallet, and as long as you keep your private key, no one can take it away from you. assets.

As a result, you hand over decentralized assets to some centralized platforms far abroad.

Let’s analyze it from another angle

The private key is a 256-bit binary code, encoded into numbers and letters. Finally, it is mapped into words to facilitate memory, also called mnemonics.

Some wallets have different mnemonics. The mnemonic phrase for plus is a bunch of random characters. Some wallet mnemonics must be made in Chinese, etc.

In short, the core of the blockchain wallet is to allow you to deposit mainstream currencies into his wallet, and then return to you a lot of their platform coins. Your currency is money, and its currency can only be coins. If you recommend others to come here to deposit coins, you will also get promotion benefits. In fact, you can understand its essence if you think about it. It is the same as getting money back, but it is just using coins. Then I will tell you my capital flow. It is safe. You don’t have to worry about crashing or running away, because I don’t touch the money. Who am I kidding? Coins are not money, right?

If you want your mnemonic phrase to be different, change it. Can it be imported into other wallets? It's definitely not possible. Only your wallet can be used. Doesn't this become a completely centralized platform?

㈨ Is it okay to invest in blockchain now? What are the precautions?

You can participate with a small amount of money. BiJing is the next generation Internet outlet. The following is my investment experience over the past year. I hope it will be helpful to you. You helped.

While I was relaxing physically and mentally during the holidays, I took stock of the pitfalls I had gone through, sorted out the gains and losses, and came to the following insights.

1. In the early days, I believed too much in the words of Big V, the big guy in the currency circle, and bought some coins from their platform. Now it is close to zero. I feel that I am so naive that I believe their lies. It is difficult for people to withstand the temptation of huge wealth, and of course they cannot escape. But saying one thing and doing another, and not admitting it in the end, has lost their moral bottom line. They have made a lot of money, leaving me waiting for Leek to stand on the top of the mountain and tremble.

2. The judgment of various public accounts and various media in the currency circle on market trends is similar to the effect of betting on dice. Of course, this does not mean that the media is completely irresponsible or thatAbility is not enough. In fact, some media still cherish their feathers and do their best to analyze projects and judge trends for fans. But don’t forget that, by nature, the market is unpredictable, otherwise it wouldn’t be called a market. Bankers and leeks are always playing a cat-and-mouse game. The media’s predictions often provide savvy bankers with guidance on reverse actions. When most media are optimistic about the market, it is also when the bankers raise their sickles; when the media generally believes that When the market is still going deep, the market makers may be building positions secretly. This is not difficult to understand, because the media acts as the opinion leader of the leeks.

3. The current market still shows the characteristics of capital market, which is dominated by speculation, and the real value investment of blockchain has not yet been reflected. The performance is that almost all altcoins are linked to the rise and fall of Bitcoin. Why is it related to Bitcoin? Because there are no other standards to rely on? If there is no killer application, this linkage effect will be difficult to break, and there will be no real bull market in the currency market. The killer application mentioned here is not like Ethereum, issuing coins, building an underlying public chain, etc., but having real application scenarios that can link virtual digital assets on the chain to reality. In the supply and demand of the scene, DAPP must have a good user experience and be accepted by the public outside the currency circle. In this case, digital currency will have real support, and the development of blockchain will usher in spring, otherwise it will be just speculation.

4. Often start from historical phenomena to form expectations for the future. In 2017, some altcoins had a market price of a hundred times or even higher. Therefore, I always feel that the altcoin in my hand has increased three to five times after I bought it, which is not satisfactory and not in place. As a result, I did not sell it in time and ended up rotting in my hands. Let's analyze it. This time is not that time. At that time, there were fewer projects and more funds. At this time, there are more projects and less funds. The situation is exactly the opposite. Ignorance and greed are very dangerous. Since 2018, as the big Vs have made profits and left the market, the funds on the market have shrunk significantly. Even if the market rises, the original market funds are playing the game. The money-making effect is getting smaller and smaller. OTC funds are waiting and watching. Only Only when the wealth-creating effect appears will OTC funds have the urge to come in.

5. New ways of playing are constantly emerging. As the money-making effect becomes smaller and smaller, new leeks become old leeks, and it is difficult to harvest them with traditional harvesting methods. Only by making some innovations can the leeks flock to it and obey. Fcoin trading and mining, Huoniu video, etc. have made a small group of people rich, and at the same time made a large group of people miserable. These projects are essentially a drum-passing fund-raising game, changing the soup without changing the medicine. The earlier you participate, the better the results will be. By the time I wait for Leek to participate, it will basically be in the mid-to-late stage. If I invest money in it, it will definitely be harvested. Since I participated in Fcoin early, I made a small profit, but I participated in Huoniu late, and was cut as soon as I entered. Fortunately, I only invested a little tentatively.

6. Will the market rise again? The answer is yes. From two aspects. On the one hand, there is a consensus that blockchain is the future trend. It is said that there is a rule that can prove whether a technology can be used in the futureWhether it can become a trend depends largely on whether the number of articles published about this technology can double every year. Blockchain fully complies with this law. On the other hand, as mentioned earlier, the current market is mainly capital. So even if blockchain is not a future trend, it will still have a good market. Because the characteristic of the capital market is that when funds enter the market, the market will rise, and when funds withdraw from the market, the market will fall, and there is no need for a reason for funds to enter and exit the market. Currently, the funds on the market include not only retail investors, but also large investors and institutions. It is not only leeks that are trapped, but also bankers who have cut the vegetables but failed to harvest. No matter who you are, there is only one purpose for entering the currency circle, and that is to make money. If the market does not rise, there will be no big money-making effect. If it falls for a long time, it will rise. This is an unbreakable rule. Of course, whether retail investors can make money depends on themselves. of good fortune.

Future plans:

1. Best policy. Strictly control positions, adjust layout, and stay away from air coins. Position control is always the first priority and is the lifeline of investors. Only after losing money did I realize the importance of position control. I really regret it now. If I had entered the dissatisfied position, I wouldn't have been so deeply trapped. Now that the matter has come to this, if we decisively liquidate all air-related projects, we can free up some funds. Then, select a few high-quality projects for fixed investment. If you don't have enough funds, you can spend a small part of it from your daily income. To do this step well, you need to add an important link, which is learning. The reason why I couldn't distinguish between good and bad projects in the past was that I didn't study enough and my skills were shallow. Instead of focusing your time and energy on watching the market, checking public accounts, and asking for news, it is better to focus on studying. Accumulated knowledge and skills are also a kind of wealth, and no one can take them away. It is necessary to learn basic knowledge about economics, finance and investment, but also to learn about blockchain. I have read some books (General Economics, Economics in One Lesson, Xiang Shuai’s Peking University Finance Course (subscription required, electronic version not available), Buffett’s Law, Buffett Teaches You to Read Financial Reports, Blockchain Technology Guide, Decoding Zone Blockchain complete set), the link address is given (link:

2. The middle strategy. Do an oversold rebound. The small money-making effect does not mean that there is no money-making effect. You must enter the market with a small amount of money, you must focus on one or two projects, and you must move in and out quickly when there is a sharp decline that makes most people panic. You must not be reluctant to fight. (You can pay attention to one or two large public accounts to judge the panic in the market.)

3. Make the final decision. Be a wool party. On the premise of not expending energy, it is not a bad idea to receive candies and get some benefits. Under the current market situation, grasshoppers are also meat. The traditional way of receiving candy is too troublesome, and the gain is not worth the loss. Found two candy delivery platform projects, one is Fulcrum:

The other is Ant Mine Chicken:

The former airdrops various candies from time to time, and also has community social attributes, forming a system It has achieved strategic investment from Binance and Huobi; the latter is a new candy game platform under the Candy World, and is actively developing chicken-laying egg-laying games.Leicandy, it is reported, has just received strategic investment from GBls (Global Sleepless Blockchain Leaders Summit).

In addition, some Dapps that are in the testing stage are also worth a try. Anyway, it doesn’t involve any energy, just think of it as a way to relax after stressful work.
