㈠ How to identify and prevent online financial "blockchain, virtual currency" fraud and MLM schemes

According to incomplete statistics, there are more than a thousand MLM platforms in my country that use the blockchain concept . It can be said that from the "highbrow" to "the mud and sand", this kind of "old wine in a new pot" online fraud MLM has been enduring for a long time and is thought-provoking.

To sum up, these blockchain frauds are nothing more than these two common methods:

One is to "sell dog meat under the false pretenses" and conduct pyramid schemes in the name of "virtual currency" The truth. For example, for the FT coin on the Fcoin exchange, investors feel that this trading dividend model can be maintained. However, once no new people enter the market to buy it, it will be enough to cause it to collapse.

The other is the so-called "export to domestic sales". For example, in the "OneCoin" case involving a total amount of 1.6 billion yuan, the organization's MLM website and marketing model were established by a Bulgarian organization, and the server was located in Denmark. After my country banned ICOs and closed domestic virtual currency exchanges in accordance with the law, fraud organizations continued to defraud under the slogan of "export to domestic sales".

㈡ In addition to being used in virtual currencies, what other aspects can blockchain technology be applied to?

In addition to being used in virtual currencies, blockchain technology can also be used in In the financial field, digital currency, securities trading, fund management, customer credit reporting and anti-fraud, digital points, etc. The usage rate of blockchain in our country is still relatively high at present. Perhaps what we have heard the most before is that it is used in virtual currency.

In summary, in today’s society, blockchain technology has provided us with a wide range of help, and we must make good use of this Technology, use it in various related industries to make our industry develop faster and ensure the interests of our people.

㈢ What is blockchain mining and what does it do? Detailed introduction to blockchain and virtual currency

When Bitcoin was first released, people discovered that it was decentralized and not It is controlled by any center; it is completely open, except for the encryption of transaction information, the entire system information is highly transparent, and the technology is open source; security, as long as you cannot control %51 of all nodes, you cannot modify the data arbitrarily, which makes it relatively safe ; Independence, the entire model and Bitcoin do not rely on any third party, all nodes verify and exchange data within the system without any intervention

Here we explain in detail what blockchain technology is, to put it bluntly It’s block + chain, so what is “block”? What is a "chain" again?

A block is a ledger. Transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction, and at the same time Can jointly testify for it

Each block contains the cryptographic hash of the previous block, the corresponding timestamp, and transaction data (usually using a Merkle tree (Merkle tree)kle tree) algorithm calculated hash value representation), this design makes the block content difficult to tamper with. Distributed ledgers connected by blockchain technology can effectively record transactions between two parties and permanently verify the transaction.

The function of the hash function h(): convert a string of any length into a fixed-length (for example, 256 bits) output. The output is also called a hash value. This output is irreversible

It is difficult to find two different x and y such that h(x) = h(y), that is, two different inputs, There will be different output. Theoretically, two different inputs may have different outputs, but this is almost impossible. For example, if an infinite space is mapped to a finite space, there must be a many-to-one situation. The theory exists, but there are no rules. It is guaranteed that you cannot find this result through any mathematical inference. Why is it 256 bits here? Isn't it longer? Because 256 bits are secure enough.

Split the ledger into blocks. For example, a piece of paper in a book is a block. Each block records transactions within a period of time, such as 10 minutes.

We divide Each piece of paper is compared to a block. A part of content is added to each block. We call it a block header, which records the hash value of the parent block. Each block stores the hash value of the parent block. , connect all blocks smoothly to form a blockchain

Record the hash value of block 1 to the block header of block 2. In this way, the block header of each block is recorded The hash value of the parent block, each block is linked in order, this is called a blockchain. The first block has no block header and is also called the genesis block

The blockchain is a ledger. Only when transactions occur in the ledger will the money in your account increase. If you need to make a transaction, you first need an account number and password. Just like your bank card has an account number and password, others can make a transfer to you. The account password on the block ledger is the public key and private key

Lao Wang (who already has a private key and a public key) wants to transfer 10 BTC to Zhang, which requires some operations

It is proved that Lao Wang himself issued the transfer signature function Sign (Lao Wang’s private key + Transfer information: Lao Wang transferred 10 BTC to Zhang San) = signature of this special account
The verification is that Lao Wang himself issued the transfer verification function Verify (Lao Wang’s address + Transfer details: Lao Wang transferred 10 BTC to Zhang San) + Signature of this transfer) = true
Once the transfer is recorded in the block, no one can change it. Zhang San will increase it by 10 BTC, and Lao Wang will decrease it by 10 BTC accordingly. The entire operation is automatic, such as your wallet The app will help you do this. The app knows your private key.You tell the wallet the transaction content, the wallet signature is announced to the entire network, and you wait for others to verify the transaction

Centralized accounting will be more efficient. Banks, governments, or Alipay can help you keep accounts, and they are all reliable. , because they can’t touch your money unless they have your private key

There are some shortcomings in centralized accounting

In decentralization, everyone can keep accounts, and everyone can A complete ledger can be kept. Anyone can download open source programs, participate in Bitcoin's p2p network, monitor transactions sent from all over the world, become an accounting node, and participate in accounting. Suppose Xiaoyi releases a transaction and broadcasts it to the entire network, and accounting node A listens. When this transaction arrives, A verifies that the transaction bit is true and puts it into the transaction pool to continue to spread to other nodes. Because it is spread through the network, the transaction pools of different accounting nodes are not necessarily the same at the same time. Every 10 minutes, from all accounting nodes Among the nodes, select one according to a certain method. After verifying that the transaction of this node is true, then compare the transaction records in the transaction pool of this selected node with the transaction records in the transaction pool of your own (A) node. The comparison is completed. After that, the transactions recorded by the selected accounting nodes will be deleted from the transaction pool, and the other accounting nodes will continue to record and wait for the next selection. There is a cycle every 10 minutes. During this 10 minutes, all accounting nodes will record accounts normally. , 10 minutes later, a node will be selected to use the transactions in its transaction pool as a new block. This block comes from the transaction pool of an accounting node I randomly selected among all the accounting nodes, and the cycle continues

A transaction is not completed once it is recorded. Only when the transaction becomes a certain block, the transaction is truly completed. This is a complete accounting process of decentralization. Your transaction will not be recorded immediately because the p2p network propagation takes time. If the node of the selected block has not received your transaction, the transaction will be not done. A block is generated every 10 minutes, but not all transactions within 10 minutes can be recorded. 10 minutes is just an average value

Due to the characteristics of decentralized accounting, accounting nodes with accounting rights will receive a 50BTC reward every ten minutes, which is about the same for every 210,000 blocks. In 4 years, the reward is halved. Bitcoin has been halved twice since its issuance. Then a new block is generated every ten minutes. The reward for this accounting node is 10.5 BTC. If it is halved every 4 years, the total number of BTC can be calculated. The amount is approximately 21 million, and it is expected to be mined in 2040. Recording the reward of a block is also the only way to issue Bitcoin. When BTC is mined, the only income that the accounting node can obtain is the transaction fee.

Accounting nodes compete for accounting rights through questions,

Find a certain random number that makes the equation invalid
SHA256 hash function (random number + parent block hashValue + Transaction in the transaction pool) A certain specified value)
There is no other solution except traversing the random numbers starting from 0 and trying your luck. The process of solving the problem is also called mining, so the accounting node to solve this problem Also known as miners, the faster you traverse random numbers, the greater the possibility of obtaining the accounting rights. This traversal speed is called computing power by mine bosses. In order to obtain this computing power, mine bosses More mining machines with higher computing power will be purchased

Whoever solves the problem correctly first will get the accounting rights. Accounting node A is the first to find the solution, which is announced to the entire network. After other nodes verify that it is correct, node A obtains the block, gains 12.5 BTC, and restarts a new round of calculation after the new block. This method is called (POW) allocating accounting rights

It usually takes about 10 minutes to solve this random number. 10 is not absolute, because the process of solving this problem is a process of luck. In response to changes in computing power in the future, Bitcoin will increase or decrease the difficulty every 2016 blocks, about two weeks, so that the average block generation time is ten minutes

Each block contains The encrypted hash of the previous block, the corresponding timestamp, and the transaction data (usually represented by a hash value calculated by the Merkle tree algorithm) are included. This design makes the block content difficult to tamper with. Distributed ledgers connected by blockchain technology can effectively record transactions between two parties and permanently verify the transaction.

Different from traditional stored data, each node of the blockchain stores complete data according to the block chain structure. Each node of the blockchain is independent and has equal status, relying on The consensus mechanism ensures storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through a central node.

Mahjong is a traditional Chinese blockchain project. A group of four miners work together. The miner who first collides with the correct hash value of 13 numbers can obtain the accounting rights and be rewarded.

Many people say that blockchain is a scam and Bitcoin is a scam. This may be a scam, but this technology has been widely recognized and applied. The cryptography knowledge involved in blockchain can only be used by ordinary people. Even if you don’t understand it, the most important thing is to look at the problem from a relatively rational perspective. Don’t let the wind be the rain.

There is something incredible about this technology. It maintains absolute order without a center or supervision. This is the trust that only needs to be established by everyone’s consensus. Bitcoin created this consensus, and in the blockchain In the world everyone is fair and equal.

㈣ The virtual currency fund scam in the blockchain

First, all virtual currencies that are not satisfied by virtual currencies are centralized. These virtual currencies that die in the entire system Currency has entered the 2.0 era, and the concept of smart contracts has been added. The entire process runs automatically and does not depend on anyone.Transfer of will. In this regard, virtual currency does not meet the characteristics of financial fraud

Secondly, virtual currency does not have an agreed high rate of return. The value of virtual currency is determined by the consensus of everyone, and it may rise or depreciate. Possibility, 24 hours of uninterrupted chaos, no one can guarantee a stable high yield when investing in virtual currencies. Bitcoin has fallen by more than 70% at the beginning of the year, and virtual currencies have fallen many times in history

Third, virtual currency does not rely on multi-level circulation. I have never introduced virtual currency investment to my friends around me. Unless my friends voluntarily propose it, I believe it is very high-risk for everyone. Even Teacher Li Xiaolai’s candy project provides There are only candy tokens

Therefore, blockchain virtual currency is not a fraud, but now many people use the banner of blockchain to play fake goods in virtual currency and destroy the market reputation. There are so many misunderstandings. However, it is also possible to encounter fraud and air currency, but blockchain and virtual currency cannot be completely equated with fraud.

㈤ Is blockchain a virtual currency?

Formal area Blockchain companies are not coins. Blockchain traceability combats counterfeit and false information.
In the past two years, the word blockchain has been very popular, and blockchain e-commerce will undoubtedly be the biggest trend in the next ten years. However, the industry is full of chaos. Many people think that blockchain is just a currency when they hear it, and they have many misunderstandings about blockchain. So before talking about blockchain, we must first talk about blockchain thinking.
Most people now understand blockchain as "coin". There are too many coins in the currency circle, such as Bitcoin and that coin. In fact, blockchain has nothing to do with currency. It is a technology, a business ecosystem, and an idea. It is mainly used in every field. It is very similar to the Internet. Talking about blockchain now is like the Internet 20 years ago. What were we talking about on the Internet twenty years ago? Talking about its technical architecture, operating system, language, server, etc., at that time, people said that Internet e-commerce was a lie because many people had not been exposed to it. In fact, many people feel the same way about blockchain now, especially after being confused by the currency circle, they have a lot of misunderstandings about blockchain.
When did Jiuling Blockchain start? Jiuling started its investigation and preparation in 2016, and it took about half a year to inspect all aspects of the blockchain. In 2017, it began to fully invest in the blockchain field. As of 2020, it is already in its fifth year. It has gained a lot of experience and achieved a lot of results in application. We have never played with coins or conducted an ICO. In the first few years, we didn’t make a lot of noise. We just worked hard to make the technology better, build the platform better, make the browser better, and apply it in terms of traceability. We have done relatively well in the application of traceability since 2017, and many products have been launched. In 2018, more than 10,000 products were applied in traceability. In 2019, we have taken it a step further. This year, we have even gone a step further. In terms of full-process visualization, Get them all open. So when I first started,We are using it in the field of traceability. Since 2018, we have used it in the entire blockchain ecosystem, including blockchain traceability, blockchain invoices, sharing economy, supply chain finance, universal points, etc. There are also platform technology services we have built. We have fully entered this field, and are relatively mature and fully implemented.
Also, why is blockchain so popular now? Why has the development of blockchain reached the level of "ideology"? This is in line with the development trend of the times.
Let’s review the history of China’s economic development in recent decades. The wealth of the Chiang Kai-shek era was concentrated in the local tyrants, evil gentry and warlords. However, Mao Zedong liberated the majority of the people who were farmers and united the majority of the people, which was more suitable for China's situation at that time. Therefore, he defeated Chiang Kai-shek, overthrew the bureaucracy of the local tyrants, evil gentry and warlords, and put their Wealth was redistributed, productivity was developed again, and revolution and distribution were completely remade. Mao Zedong truly served the people and allowed the people to live a good life. Entering the era of large collectives, people go to work in the countryside to earn work points, and how much food you can get according to the work points you earn. During the Deng Xiaoping era, I felt that this was wrong. It might be because of inefficiency and eating from a big pot. Later, the reform and opening up began. After the reform and opening up, fields were assigned to households according to the number of people. After the distribution to each household, the output increased a lot, and everyone's income was reduced. Passion was stimulated, which increased production and efficiency. After the reform and opening up, commercial and industrial enterprises began to develop.
It can be seen that economic development is based on the needs of the times. China has been reforming and opening up for decades, and has moved from a traditional economic era to an e-commerce Internet economy. Now that blockchain has emerged, it is also because new problems have arisen in wealth distribution in the Internet era.
In the Internet era, social wealth is highly concentrated on several platforms, such as Alibaba, Tencent, Internet, JD.com, etc. Internet e-commerce leaders have a monopoly on finance, resources, and have too much say in products and other aspects. powerful. Social development has completely lost its balance. The uneven distribution of wealth has made the rich richer and the poor poorer. Those who have no money include the entire industrial enterprises in China. Except for the monopoly central enterprises, most enterprises are now very poor. It is difficult to survive. At this time, another business revolution is needed, and productivity must be redistributed and readjusted. It just so happens that blockchain was born in response to the needs of the times.
The rules and mechanisms of the blockchain are completely open and fair, cannot be tampered with, and are decentralized. It removes the oligarchs of the organization and forms a shared economy for common development. Why does the government support blockchain so much? Because the government can fully enter the blockchain field for supervision, and the privacy of individual citizens can be protected. Personal information on the Internet cannot be protected, but personal information in the blockchain is in your own hands. In the era of Internet e-commerce, oligopoly organizations have monopolized information resources. There are too many fake and shoddy products and too much false information, making it impossible for us to distinguish them.
At this time, the blockchain is decentralizedSupervision rules and mechanisms emerged as the times require. Blockchain is not only a technology (some improvements have been made on the original Internet technology), but more importantly, it is used in applications to solve problems that cannot be solved by the Internet, traditional e-commerce, and traditional ecology, such as traceability. Traceability in the Internet era can be faked. A traceability code can be posted anywhere, but blockchain traceability is different. Blockchain technology is real and everyone can participate together. Through distributed storage, everyone who participates can Everyone can get this data, and then everything can be traced to its source, including products and invoices, including a message sent by a person, which can be traced, stored, and kept true.
Blockchain traceability starts from raw materials, to production and processing, to warehousing, sales, etc. Every link must be fully visualized, with pictures, videos, and text, and every step must be left behind. Traces of links. Only with this kind of mechanism can everyone be completely trusted and be fair, open and transparent in the current situation where there are too many counterfeits and shoddy products and a lack of trust. In short, what blockchain wants to solve are problems that the Internet cannot solve.
Speaking of blockchain, the first thing that many people think of is Bitcoin. Bitcoin's actual contribution to the world is to propose a rule and mechanism. Bitcoin itself has no value, it has no products and no support. But its technology and concept are very good, because this technology cannot be faked. The source code of this technology is open source and can be shared. Its technology uses the idea of ​​​​blockchain.
The rules and mechanisms of blockchain have been sought after by everyone as soon as they came out. However, in the past few years, they have been confused by currencies. That kind of currency is simply deceptive and goes against the blockchain. Instead, it makes people confused. Everyone no longer trusts the blockchain because they don’t know enough about the blockchain and think that the blockchain is just a currency. Because I want to understand a field, just like Jiuling Blockchain has entered its fifth year, and it is engaged in blockchain ecology, blockchain traceability, blockchain digital points, blockchain technology development, The development of blockchain browsers, etc., are still learning in this field, because it is not easy to learn thoroughly in a field. The reason why we have been very motivated in the past few years is because we know it is a big trend and coming. Just like the Internet 20 years ago, many people didn't believe, didn't understand, and turned a deaf ear. But 10 years ago, big companies like Tencent, Alibaba, and Huawei had emerged. At the same time, this opportunity is now in front of us. Can we seize it? Well, this is a question worth thinking about.
Finally, I want to make it clear to everyone that blockchain has nothing to do with currency at all.
For formal blockchain companies, the government has requirements and certification standards.
Standards: 3 basic requirements (a patent, soft copy, company registration in a national blockchain park, paid-in registered capital, dedicated blockchain R&D funds), 4 implementation application standards (must There are blockchain browsers, websites, blockchain application scenarios, and blockchain products), and 5 types of blockchain professionals (Blockchain financial professionals, blockchain digital professionals, blockchain credit management professionals, blockchain software development professionals, blockchain encryption technology professionals, employees with a bachelor's degree or above who have been employed for more than one year) can get 6 a basic subsidy.
The blockchain industry is a mixed bag. There are at least tens of thousands of cryptocurrency and ICU companies. They all claim that they are formal, but can they produce these certificates? The document states that as long as a company has a digital currency or ICO, it is not a blockchain company.
Under the background of this era, the ideas, rules and mechanisms of blockchain, decentralized supervision, and privacy and confidentiality distribution can protect everyone’s interests, redistribute productive assets, and prevent interests from being too concentrated in certain groups. For oligarchs and institutions, let everyone participate and use their energy to fight against counterfeiting, tax evasion, and false transactions, so as to create an ecosystem that protects the interests of the people, is conscientious, and can provide hematopoietic functions. This is the true purpose of blockchain.

㈥ What is blockchain? Blockchain is virtual currency

Let me tell you about blockchain in a simple way. There is no need to use advanced professional terms, because That's too difficult to understand. Let me give you an analogy to make sure you understand it at a glance.

Chinese mahjong can be understood as blockchain. If the four of you ABCD are going to play mahjong, who will say hello? If A greets, then A is the initiator of this block. A is responsible for finding the mahjong parlor. Organizer A can invite BCD, or B can invite C or C can invite D. It doesn't matter.

abcd gathered in a mahjong parlor and started playing mahjong. The process of shuffling the cards in the mahjong machine, drawing cards, and playing cards by abcd can be understood as a mining stage similar to Bitcoin in the blockchain.

Everyone has different cards, which is equivalent to the algorithm in the block, but there is a goal, and they are all for the purpose of cheating. Among them, A cheated, and bcd said nothing. , everyone knows at a glance that A has won. This is called the consensus mechanism in the blockchain.

A is messed up. After A knocked down the mahjong, bcd all know how A got confused and remember it in their hearts. If A wins 10 yuan, both AbCD and A will know that A wins 10 yuan. , this is called distributed accounting in the blockchain.

Everyone who plays mahjong knows what mahjong arrangement can be used, and everyone also knows what cards can be doubled, so this can be understood as a smart contract in the blockchain.

Everyone knows the final winning card of A after A is knocked down. No one can tamper with this result because everyone is watching it. This can be understood as the immutability of the blockchain. sex.

After A announced that he was cheating, everyone did not go to another person, such as E, F, G... to verify. The same was true after B won... no regulatory agency can control it They all manage themselves. This is the decentralization in the blockchain.

By analogy, the four buddies abcd played mahjong for a day, and abcd recorded every win or loss. No matter what method they used, whether it was brain memory, video recording, or notes, they The more you play, the more you can reflect the immutability, decentralization, distributed accounting, and consensus of the blockchain...

At this point, you basically understand Have you ever understood what blockchain is? Isn’t it very simple?

The second question is that blockchain is not a virtual currency. Virtual currency is just a part of blockchain technology.

Many people think that virtual currency is the blockchain and Bitcoin is the blockchain. This is actually wrong. It’s just that the fame of Bitcoin has brought blockchain into the public eye.

Satoshi Nakamoto invented Bitcoin using blockchain technology, and he defined Bitcoin as a peer-to-peer electronic cash system. The term "electronic cash" indicates that what Satoshi Nakamoto wanted to invent was not Not just a payment system, but a monetary system with an independent monetary philosophy.

Today’s hotly-hyped virtual currencies, as well as mining, are resisted by many departments and countries. The fundamental purpose is not to waste resources, electricity, etc., but because people with blockchain technology Virtual currency has subverted traditional finance and can easily cause the collapse of traditional finance. I have talked about this in my previous Q&A, so I won’t go into details here.

It can be said that Satoshi Nakamoto and the Bitcoin he invented are the pioneers of the blockchain. It was Satoshi Nakamoto who brought blockchain technology into everyone’s field of vision. Blockchain technology is still widely used in finance, medical care, service industry, big data security...

Let’s talk about this big data. As we all know, the recent Didi incident due to big data security The impact is still quite large. If decentralization in blockchain technology is used, personal data can be obtained and saved through the blockchain. How can there be data leakage? In today's society, with the advancement of science and technology, as long as you use your mobile phone to connect to the Internet, you have no data security. Your personal information has already been leaked completely, so blockchain technology is inevitable for social progress. trend.

Let’s talk about blockchain. I hope you can learn something from it. You can also pay more attention to blockchain technology and improve your cognitive level. (Personally coded by hand)

Blockchain is a distributed storage solution.

Virtual currency is a supporting reward mechanism to promote this plan.

The blockchain is decentralized, so there will be no IDC computer room or centralized data center. The storage of all data is theoretically fragmented. This requires a reward to attract others to join the project, and this reward is virtual currency.

In theory, blockchain can form a dynamic and stable mergerCentralized cloud-like computing resources provide channels.

Bitcoin is the earliest blockchain application, while Ethereum is a second-generation blockchain that can support on-chain applications. The hardware resources required for these applications are provided by miners, so they must be paid Miners pay a certain fee, and the common currency used for this fee is Ethereum.

The biggest attraction of blockchain is decentralization. In theory, applications on the chain will not disappear. No cloud containers will be lost, no data centers will be blown away by typhoons, and there will be no An organization can decide whether it stays or goes.

However, the reality is that there are still a lot of problems in on-chain applications, such as high latency, imperfect infrastructure, the reward-based miner attraction mechanism has not accelerated the on-chain speed as expected, and the virtual currency has prospered alone. Centralization returns to centralized exchanges, and other issues. There is also the inflow of black money, which is making this emerging industry full of uncertainty.

But from a technical perspective, blockchain technology is indeed the next generation of computer application technology.

Blockchain is a technology, a distributed and decentralized technology that can be applied to storage. Blockchain is not a virtual currency. Virtual currency is just a digital currency made using blockchain technology. Now, for example, the relationship between blockchain and digital currency is like, for example, if you build a dapp application mall on a certain chain, then you A token related to this mall can be issued.

The real connection between blockchain and virtual currency

What we are pursuing now is the application of blockchain technology. You develop a public chain and build many shopping malls, finance, defi, real estate, and tourism on this public chain. Such a dapp, this public chain has value, and then the tokens issued by this public chain have value, just like the current Ethereum, pi network

There are too many on the Internet now The so-called "blockchain digital currency", when we look at virtual currency, we look at what problems the public chain it is on can solve and what value it has, rather than blindly hype it. I think blockchain is the underlying technology. I think we only know The surface of blockchain.

Author: Leng Leng's point of view

Block Chain is a technology, and virtual currencies like Bitcoin are products of applications on the blockchain. There are many video explanations on my homepage.

Blockchain is a technology, and virtual currency is a product produced by applying blockchain technology.

Bitcoin brought out blockchain technology, making people who don’t know why think that Bitcoin is equivalent to blockchain.

What is blockchain?

Every computer (mobile phone) is a block, which is connected through the Internet to form a blockchain.

Different from the traditional Internet, on the traditional Internet, such as playing Douyin, each of us is invitedPlease ask Douyin server, Douyin server to give us videos. Everyone who plays Douyin cannot do without the Douyin server, and the Douyin server is our center. There is no center in the blockchain. Everyone (each block) is a server. When a block generates new content, everyone will be notified and everyone will save the new content to their own server. Each block saves The content is the same. If a new user (block) joins, it needs to synchronize the data on the blockchain and update the data to its own server first.

The advantage of blockchain is that it can ensure data security and cannot change the data. It is useless if you change one or two blocks of data. Once the blockchain data is synchronized, it will become the correct value. The traditional central server will not work. Hackers invaded the Douyin server, and all users suffered.

Disadvantages of blockchain are low efficiency. Blockchain requires synchronization of blockchain data in each block. New changes on the blockchain require simultaneous updates from users on the entire blockchain network, which is inefficient.

Blockchain is a computer model of distributed data storage, point-to-point transmission, and consensus mechanism. In simple terms, blockchain is a decentralized database. How to use this technology? Is the value reflected? Under the consensus mechanism, a technology such as blockchain is formed to give a specific token, which is BTC

Blockchain is a new Internet application technology that uses distributed storage, passwords The application of emerging technologies such as science, smart contracts, and consensus algorithms can be said to be a new data transmission method that innovates existing Internet protocols. At present, blockchain technology is constantly iterating

1. Blockchain 1.0, symbolizing the birth of Bitcoin; only with Bitcoin can the development of blockchain technology officially occur

2 , Blockchain 2.0, Ethereum decentralized application platform, Ethereum introduces the application of smart contracts, which represents the beginning of a new era of blockchain technology; now everyone can create projects on Ethereum, and in recent years Many good projects have been launched

3. Blockchain 3.0, DeFi opens the era of decentralized finance. DeFi projects use smart contract technology to realize various functions of traditional financial institutions, such as derivatives, Lending, trading, financial management, asset management, and insurance, etc. There are currently mixed reviews for DEFI, which will take time to verify

Although the blockchain originated from Bitcoin, just like the first computer when the Internet first appeared, Bitcoin is mainly used by miners. Mining rewards

Blockchain is a decentralized accounting method. Virtual currency is the product of blockchain.

㈦ What is virtual currency

This is the answer to this question found on the Internet: Virtual currency refers to non-real currency. Well-known virtual currencies include Internet coins of Internet companies, Q coins of Tencent, Q points, point coupons of Shanda, and micro coins launched by Sina (used in micro games and Sina reading).etc.), Chivalry Yuanbao (used in the Chivalrous Way game), Wen Yin (used in the Bixue Qingtian game), the popular digital currencies in 2013 include Bitcoin, Litecoin, Infinity Coin, Quark Coin, Zeta Coin, and Barbeque Coin , penny coins (external network), invisible gold bars, red coins, prime coins. There are currently hundreds of digital currencies issued around the world. The legends of "Bit Gold, Lite Silver, Infinite Copper, and Penny Aluminum" are popular in the industry. I would also like to add that virtual currencies can be divided into two major categories according to the issuer: one is virtual currency like Bitcoin that is issued and endorsed by no clear authoritative institution or individual, and the other is virtual currency like Internet currency, Virtual currencies such as Venezuela’s petro are issued and endorsed by clear and authoritative institutions. Relatively speaking, the former generally has no actual value and the risk is extremely high, while the latter generally has actual value and the risk is relatively controllable. For example, Venezuela’s petro currency is a valuable virtual currency backed by the credibility of the current Venezuelan government and its oil reserves.

I am honored to answer your questions

Virtual currency is an investment product that has emerged around the world. It has caused a craze in the investment market, so we need to understand what virtual currency is.

Bitcoin is the world's first virtual currency. Virtual currency is created using password authentication and computer calculation programs. It is a virtual currency with a limited quantity and individual characteristics. We can trade, pay, or It is for storage purposes.

Example: The upper limit of the number of Bitcoins is 21 million, but the number of Bitcoins currently circulating in the market is only 18 million jins. Because people are worried about the reduction in the purchasing power of traditional currencies, investors have changed their investment strategies and bought virtual currencies with a limited amount.

Because of the unique characteristics and rare relationship of virtual currency, and virtual currency is a better investment tool in terms of asset preservation, so it attracts investors to enter the virtual currency market. Unlike traditional instruments of value such as gold and silver, the advantage of virtual currencies is portability. Because the global communication network is technologically advanced and wireless Internet (Wi-Fi) and mobile phone network coverage are large, transactions and payments can be easily conducted online in different countries.

Hope this helps you understand.

The only function is to replace real currency to facilitate transactions.

In essence, currency itself is a substitute, so it can be replaced by anything, that is, it can be The metal can also be banknotes, and of course data with special meaning can also be used.

Most of the virtual currencies mentioned now can be simply understood as the equity of the crowdfunding project, that is, this project needs funds now, everyone contributes money to build it, and if it is completed, it will be based on your equity. It is the number of coins divided into dividends.

But the reason why the country currently prohibits the initial issuance of tokens is to issue new virtual currencies. This is because many people directly use an APP. When the project is completely suitable for concepts, there is even no concept. I'll start issuing money soon.

Virtual currency is an Internet digital virtual currency issued by software and digital scientists based on the use of blockchain technology and quantum algorithms, decentralized, open source on famous websites, and issued to the whole world or a specific region. It is a virtual currency. Currency has the functions of currency and payment. It is currently illegal to issue digital currencies in China, but digital currencies held by citizens are classified as digital assets or virtual assets.

Virtual currency simply means that it is not real currency. Usually what we call real currency refers to banknotes, coins, etc. that we use in our daily lives.

Like QQ coins, Bitcoin, Ethereum, etc., these are virtual currencies that do not really exist in society, but are recorded digitally.

Although virtual currency has no cash value on the surface, it is still circulating in the market, and it can be said that part of it is equivalent to real currency.

With the development of the Internet, more and more virtual currencies appear in the market, and it is possible that they will replace real currencies in the near future.

Virtual currency is real currency in a non-traditional sense. Putting aside the virtual currencies created by Internet companies such as QQ Coin and circulated on their own company platforms, in recent years various virtual currencies on the Internet, led by Bitcoin, have begun to break into people's field of vision. The sudden rise and fall of virtual currencies are also of this type. properties. General currencies are determined by central banks, while virtual currencies are determined by individuals. The sovereignty of general currency lies in the center of the republic; the sovereignty of virtual currency lies in distributed individual nodes. Decentralization is also a label of virtual currency.

㈧ When will blockchain technology explode? Can virtual currencies bring cross-class opportunities to ordinary people?

Virtual currencies are decentralized and not linked to anything. They are completely dependent on A product supported by the consensus of the community. Take Bitcoin, for example. Because the community consensus finds it valuable, Bitcoin continues to rise until today. However, there are real and fake projects behind virtual currencies, and their values ​​vary. For ordinary people, choice often outweighs effort. Every year, there are people who achieve financial freedom because of virtual currencies, but losses are the ultimate destination for most people. It is very dangerous for ordinary people to participate in virtual currency transactions in an unregulated market that relies entirely on consensus. Don’t blindly think that you are the lucky one who will achieve cross-class status, because capital is always cruel.

Not all virtual currencies can be guided by decentralized blockchain technology. Most virtual currencies just pretend to be virtual currencies on the technical side of the blockchain. In fact, it confuses the concept and there is no new round of leek harvesting model that breaks away from centralization.

This involves several common sense things, what is a blockchain, what is a virtual currency, and what is decentralization.

1. So what is blockchain?

Blockchain originated from Bitcoin. Blockchain is a distributed shared ledger and database. It has the characteristics of decentralization, non-tampering, full traces, traceability, collective maintenance, openness and transparency. .

2. What is virtual currency?

Virtual currency refers to non-real currency. A string of network codes without any physical endorsement, mortgage, or acceptance. It is divided into two types, one is a centralized virtual currency, such as Q Coin; the other is a decentralized digital currency, such as Bitcoin.

3. What is centralization and what is decentralization?

The simplest description is that QQ coins can be issued unlimitedly by Tencent. You can produce as much as you want. The final right of interpretation lies with Tencent. This is called centralization; like Bitcoin, There is a fixed number. The fixed number of Bitcoins is an upper limit of 21 million. And among the 21 million Bitcoins spread around the world, whoever has them has a say. This is called decentralization.

Only by understanding these three questions can we know the relationship between blockchain technology and virtual currency. Currently, only Bitcoin has this digital cryptocurrency on the market, and it has a fixed amount. But the biggest advantage of this thing is not its circulation, but the addition of cash currencies recognized by various countries as a means of money laundering.

So what you see as the price of Bitcoin in the national market is only the conversion rate of currency conversion given to Bitcoin in a certain transaction, not the real value. Because virtual currency itself has no physical object as acceptance.

UpdateNot to mention the so-called digital currencies issued randomly on the market, they are actually the same as Q coins. Tencent said that 1 yuan can be exchanged for a Q coin, and the price of this Q coin is 1 yuan. Two days later, it said that 10 yuan can be exchanged for a Q coin, and this Q coin is 10 yuan. But are Q coins really worth the money? You can only buy a QQ show, which is clothing in the virtual world, also called skin.

According to notices and announcements issued by the People's Bank of China and other departments, virtual currency is not issued by a monetary authority, does not have legal and compulsory monetary attributes, is not a currency in the true sense, and does not have the same characteristics as currency. Equivalent legal status, it cannot and should not be used as currency for circulation in the market, and citizens’ investment and trading in virtual currencies are not protected by law.

Various virtual currencies in the international market pretend to be international currencies under blockchain technology. In fact, they are all flowers in the moon and water in the mirror.

When blinded, coupled with greedy human nature, ordinary people can cross the border and become complete paupers, and they may have to owe a lot of debt.

As the core underlying technology, blockchain’s decentralization, openness, autonomy, non-tamperable information, anonymity and other characteristics help to establish The full-scenario smart management system provides safe, efficient and convenient services for users, smart systems, smart systems, and smart systems to support the construction of smart cities.

The so-called decentralization of virtual currency is a complete lie. It is a fantasy utopia that is absolutely impossible to realize. Virtual currency is a complete money scam. To put it bluntly, the basis for the generation and transactions of various virtual currencies is the Internet and electricity, and the construction of communication networks and power generation facilities relies on the country as the center. Just imagine, losing the country as the center, in a country without laws, without In an environment where the Internet is short of electricity, poor, or even war-torn, how about using a hammer to mine? Virtual currencies and all their lackeys are enjoying the dividends brought by the country's stability, but at the same time they are trying to break away from the center of the country to achieve their own greedy goals of getting something for nothing. Careful analysis shows that the virtual currency ecosystem, from issuance to mining to participation in transactions, combines various typical characteristics of pyramid schemes, gambling and cults. The advocates of virtual currency are a group of outright criminals and should be tried by the law!

No. From the perspective of human history, external situations such as groups of people, tribes, countries, religions, the Internet, etc. all use the propaganda and banner of people's freedom and love, but what is the result? !

Technology has been used in many industries, especially in the financial industry. In the future, with the recognition of various countries, it will definitely change the distribution of classes

Blockchain technology, in fact, that is.

Two essential shortcomings have sealed its fate.

One is that the efficiency is too low.

One is that energy consumption is too high.

SoImpossible to break out.

Crossing classes? It’s already passed, there’s no chance anymore.
