『一』 How to play virtual currency and whether it is reliable

Judging from the current situation, the scale is tilted to the "unreliable" side. Take BTC as an example. In 2017, BTC surged by 1,400%, reaching the maximum level of $20,000 per Bitcoin. But after entering 2018, the market was wailing. BTC fell by more than 50% in the first quarter, and the current price is less than 7,000 yuan. The entire digital currency market is also currently very depressed, and the prices of various currencies are falling. For example, "Ether" has dropped from more than 1,300 US dollars to around 400 yuan. More importantly, there are more and more non-good news signals released from the outside. In this ecological chain, in terms of profit distribution, the most profitable group is the group that sells virtual currency. His main task is to develop and promote the currency, and after creating the currency, strive to enter the most famous virtual currency trading markets.

Market anxiety perfectly controls this market. Entering the market involves risky investments and requires caution. The above is just a personal opinion and does not mean any analysis of investment value. Personally, I feel that virtual currency is just a manifestation of blockchain technology. The technical value of blockchain is recognized by everyone, and this is also a development trend. But blockchain application ≠ virtual currency. Of course, currently, the most common application of blockchain is in virtual currencies. With the addition of asset operations, the growth has exploded. However, the current price of virtual currency is like the temperature: fickle. However, I personally think that the overall development trend of virtual currency may be downward, but I do not rule out that it will rise in the future. At that time, it will be amazing whether it can be held back or whether it can sell high and buy low. Operation is all up to you. In addition, if any company that issues digital currency can apply blockchain applications to physical lines in the mid-to-late period, it is still very exciting.

『二』 The virtual currency fund scam in the blockchain

First, all virtual currencies that are not satisfied by virtual currencies are centralized, and these are dead in the entire system. The virtual currency has entered the 2.0 era, and the concept of smart contracts has been added. The entire process runs automatically and is not transferred according to anyone's will. In this regard, virtual currency does not meet the characteristics of fund fraud

Second, virtual currency Currency does not have an agreed high rate of return. The value of virtual currency is determined by everyone’s consensus. It may rise and depreciate. There is 24-hour chaos. If you invest in virtual currency, no one can guarantee a stable high rate of return at the beginning of the year. Bitcoin has fallen by more than 70%, and virtual currencies have fallen many times in history

Thirdly, virtual currencies do not rely on multi-level circulation. I have never introduced virtual currency investment to my friends unless they volunteer. Otherwise, everyone believes that this is a very high risk. Even Teacher Li Xiaolai’s candy project only provides candy tokens

Therefore, the blockchain virtual currency is not a fraud, but now many people pretend to The banner of blockchain is playing fakes in virtual currency and destroying the reputation of the market. There are so many misunderstandings. But, it is also possible to encounter fraud and air currency, but the blockchain and virtual currency cannot be completely equated with fraud.

『三』What is the prospect of lat currency

1. PlatON (lat coin) is a financial infrastructure based on privacy computing that can provide privacy computing services for various business scenarios. The project was founded in 2018 and was jointly built by the founders of Wanxiang Blockchain and Matrix Yuan. Both founders were born in the traditional financial industry and have rich industry resumes. The core team members have very good resumes and development experience. Backed by Wanxiang Holdings, it has abundant market cooperation resources. Project financing is about US$50 million, and product iterations are good.
2. PlatON mainly publishes privacy computing algorithms (MPC and homomorphism) through contracts, and data providers and computing nodes with privacy protection requirements cooperate to execute the computing protocol to achieve collaborative computing of data and are compatible with Ethereum The EVM virtual machine of Ethereum can support writing contracts in Solidity language to facilitate subsequent access to the Ethereum ecosystem.
3. The initial total amount of the token LAT is 10 billion, and additional blocks will be issued in the future. The value support of LAT lies in the computing power settlement on PlatON. If the network develops well in the future and the demand for computing power gradually increases, it will increase Market demand for LAT. Compared with other projects, PlatON is backed by Wanfeng Blockchain and has abundant market cooperation resources. It has considerable advantages in terms of implementation and operation in the later stages of the project. Overall, each project is still in the technology development stage and has a long way to go before it is implemented. It has future development prospects and is worthy of attention.
4. PlatON is positioned as a privacy computing network + distributed economic infrastructure. We have reached the forefront of exploration in the field of privacy computing and have many years of practical experience in large-scale distributed systems. Most importantly, we have a deep understanding and practice of the infrastructure that supports large-scale data asset transactions.
5. So in layman's terms, PlatON is a public chain featuring privacy computing, with world-leading cryptography capabilities, and its business logic is completely based on commercial use. In the future, it hopes to become a decentralized version of UnionPay and VISA, providing users with carrier-grade services.
6. Privacy computing can be well applied to commercial practices in finance, medical care, scientific research, government affairs, logistics and other industries

『四』 Does virtual currency belong to the category of online finance? According to

Digital currency naturally has a development trend. The smaller the social weight of ordinary people, the more important the social credit of money becomes. The shoddy nature of currency and credit means that ordinary people's labor income is being robbed by an invisible hand at any time. The lower the people are, the more they have to work in exchange for basic living standards; and the higher the income from labor, the more easily they are robbed by low-quality money and credit. A country’s territorial sovereignty is actually the combination of social development rights and interests.

Enter aloneBefore performing relevant operations, the server will record and update the operations. But when one server or several servers crash, other servers are still available. The State Administration of Taxation recently stated in its reply to the Beijing Municipal Local Taxation Bureau that the income I received from recycling players’ digital currencies through the Internet and selling them to others at a raised price is taxable income for personal tax and should be treated as taxable income according to the new “property transfer income”. The project calculates and pays personal income tax. According to regulations, the tax calculation method for income from property transfers is to take the total income from the one-time transfer of assets (regardless of how many payments are made, it should be combined into one-time income from the transfer of property) minus the original value of the assets and effective expenses, which is the tax payable. , a 20% tax calculation formula can be used to pay personal income tax.

『Wu』 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. , not subject to any central control; 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; independent, 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 is 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 the transaction data (usually a hash value calculated using the Merkle tree algorithm) represents), 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, such as a ledgerA piece of paper is a block, and each block records transactions within a period of time, such as 10 minutes

We compare each piece of paper to a block, and in each block The above added content is called the block header, which records the hash value of the parent block. The hash value of the parent block is stored in each block, and all blocks are smoothly connected 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 records the hash value of the parent block, and each block is linked in order. Come on, this is called 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 it waits for others to verify the transaction

Centralized accounting The efficiency will be higher. Banks, governments or Alipay will keep accounts for you, which is very reliable, because they can't touch your money unless they have your private key

There are some disadvantages in centralized accounting< /p>

In decentralization, everyone can keep accounts, and everyone can keep a complete ledger. 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 record in the selected node's transaction pool with itself (A) Compare the transaction records in the transaction pool of the node. After the comparison, the transactions recorded by the selected accounting node in its own transaction pool will be deleted, and the other transactions will continue to record and wait for the next selection, every 10 minutes. It is a cycle. During this 10 minutes, all the accounting nodes record accounts normally. After 10 minutes, a node is selected to use the transactions in its transaction pool as a new block. This block comes from all the accounting nodes that I choose arbitrarily. A transaction pool of accounting nodes, and this cycle continues

The transaction is not completed when 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 hash value + Transactions in the transaction pool) A certain specified value)
There is no other solution except traversing the random numbers starting from 0 and trying luck. The process of solving the problem is also called mining, so the accounting node that solves this problem is also called mining. It’s called a miner. The faster you traverse random numbers, the greater the possibility of getting the accounting rights. This traversal speed is called computing power by mine bosses. In order to obtain this computing power, mine bosses will Purchase more mining machines with higher computing power

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 thatThe average block generation time is ten minutes

Each block contains the cryptographic hash of the previous block, the corresponding timestamp, and transaction data (usually using the Merkle tree algorithm (represented by a calculated hash value). 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.

『Lu』 explains the digital renminbi in detail | Digital renminbi VS Alipay and WeChat: Parallel or replacement

Digital renminbi (DC/EP) is "ready to come out", what will happen to the future payment field? change?

"When private payment institutions like WeChat and Alipay become larger, they will have some impact on user privacy protection and fair market competition. DC/EP can help alleviate these impacts." Wanxiang Block Zou Chuanwei, chief economist of Lianhe PlatOn, told The Paper.

In this upcoming revolution, will Alipay, WeChat Pay and other third-party payments be safe?

Will third-party payments be affected?

In its prospectus published on August 25, Ant Group, the parent company of Alipay, reminded of the risks that may be brought about by the central bank’s digital currency. Ant Group stated that the company is actively participating in digital RMB research and development trials and is preparing for internal closed pilot testing in Shenzhen, Suzhou, Xiongan, Chengdu and future Winter Olympics scenarios according to the arrangements of the central bank. Ant Group stated that the digital renminbi is still in the pilot testing stage, and related product design and institutional arrangements are still being continuously iterated and improved. It is reported that there is no timetable for when the digital renminbi will be officially launched, and it is difficult to assess the impact of this work on the company's business, financial status and operating results.

CentralMu Changchun, director of the Bank’s Digital Currency Research Institute, once said in a public class that the central bank’s digital currency will not affect the status of Alipay and WeChat. Because currently Alipay and WeChat also use RMB for payment, which is actually payment in commercial bank deposit currency. After the central bank’s digital currency was launched, it was simply replaced with digital renminbi, which uses the central bank’s deposit currency. Although the payment tools have changed and functions have been added, the channels and scenarios have not changed.

“The central bank’s digital currency is still an (system) that is not fully formed. The current entry point is cash. If you prematurely call out to replace other parts before it has a firm foothold, it will definitely make the two parties confused. Changes in the family's strategy will have an impact on the existing payment scenarios in society," said Wang Zhicheng, associate professor at Peking University Guanghua School of Management. "I think the current public goal is to replace M0 (cash ) is also a correct entry point. After successful operation, it is very easy to further expand and replace M1 (narrow currency)."

He believes that M1 is a current account, and now WeChat and Alipay are based on current accounts , after the digital currency comes out in the future, everyone will definitely hope to have a corresponding current account, so there will definitely be a connection between the central bank's digital currency and the current account. There is a problem of interest in demand deposits, and it is easy for banks to make interfaces for this, so it should be easy to jump from M0 to M1.

Li Lihui, former president of the Bank of China and leader of the blockchain research group of the China Internet Finance Association, said in an exclusive interview with China Daily that whether the central bank’s digital currency can replace third-party payments mainly depends on its convenience. performance, reliability and security, as well as operation and maintenance and usage costs. If the application of digital currency can reach a certain scale after piloting, whether it can replace third-party payment in the future is a process of market selection.

Li Lihui said: "From the current design perspective, it may be a more certain trend for digital currency to replace bank cards to a certain extent in the future. It is expected that central bank digital currency will be used for a long time. Parallel with mature third-party payment platforms, it will become the main payment tool without quickly producing a substitution effect."

What aspects may be affected?

Deng Jianpeng, professor at China Finance Law School and director of the Financial Technology Rule of Law Research Center, wrote that there are three types of businesses of third-party payment institutions that may be affected by the central bank’s digital currency in the future. One is the payment business licensed by the central bank; the other is based on the payment platform. Businesses derived from traffic advantages, such as access to sales ports for financial products such as monetary funds; third, credit reporting and risk control-related businesses based on payment data information, such as Sesame Credit Score, which currently has a close business relationship with Alipay.

He believes that if the data generated by users based on digital currency is only provided to the central bank in the future (to ensure "controllable anonymity"), the expansion of the above-mentioned businesses of third-party institutions will inevitably face great difficulties.

Deng Jianpeng said,According to the information currently released, the central bank’s digital currency will support chip card swiping and mobile phone near field communication (NFC) on the client in the future. It can be predicted that the payment convenience of central bank digital currency is very high. More importantly, the central bank’s digital currency enjoys the credit endorsement of the central bank and has higher credibility. If the central bank's digital currency wallet is completely independent of third-party payment institutions and does not open interfaces to third-party payment institutions, then some or even most of the functions of third-party payment institutions are likely to be replaced in the future.

“Therefore, third-party payment institutions should promptly participate in the central bank’s digital currency issuance mechanism. Strong third-party payment institutions should strive to cooperate with the industrial and commercial bank of China and China Construction Bank in the digital currency issuance mechanism. banks and other commercial banks of similar status,” he wrote in the article.

What are the advantages of central bank digital currency?

What is the difference between central bank digital currency and third-party payments such as Alipay and WeChat Pay?

Mu Changchun said in the open class that first of all, from a legal perspective, DC/EP is the best in terms of effectiveness and security. WeChat and Alipay do not reach the level of Japanese paper in terms of legal status and security. banknotes at the same level.

Secondly, Mu Changchun pointed out that the central bank’s digital currency can be paid without the need for the Internet. It is called “dual offline payment”, which means that both parties to the payment and payment can be offline and can make payments. As long as the mobile phone has power, payment can be made even if the entire network is disconnected.

In an interview with China Daily, Li Lihui also said that compared with currently widely used third-party payment platforms, such as Alipay and WeChat Pay, the biggest difference between digital renminbi is that it adopts "account loose coupling + digital wallet" "mode. In this mode, there is no need to bind a bank account, and it can satisfy offline transactions when users face each other. That is, the two parties can bring the terminal devices close to each other when they are offline, and use the near field communication function to realize the exchange of value. This is also digital An important breakthrough in currency compared with third-party payment. In addition, digital currency may also have certain breakthroughs in large-value payments.

Wang Zhicheng also mentioned that offline payment is the biggest feature of the central bank’s digital currency. He said that the central bank’s digital currency has very similar functions to Alipay and WeChat payment. In terms of retail, these two payments have gone through many years of running-in and market testing. In their respective fields, user-friendliness and other aspects are relatively complete. Therefore, in these aspects of central bank digital currency, it is not enough to just learn from them. It may be necessary to make breakthroughs in more scenarios, payment channels, and targeted payments that the two companies do not have.

In addition, regarding the areas that central bank digital currency can do but third-party payment cannot cover, Wang Zhicheng said that digital currency may have a great connection with the future connection of digital assets, which is equivalent to buying things. The same medium is used for selling things. Things with similar mediums will have a better match and be easily accepted by everyone. “In the future, any financial products and transactions between virtual assets, for example, will beThe matching degree and convenience of using central bank digital currency will be much higher than the current third-party payment. "

Offline or a big problem

"Offline seems simple, but I think this is the bigger problem that the central bank's digital currency will face when it launches it. "Wang Zhicheng said.

He said that on the payment channel, the problem of switching from offline to online is not as simple as imagined. How to design the time for digital currency to go offline and return to online again, this problem is It is more difficult to solve. Due to the easy copying and modification characteristics of data and electronics, there will be many difficulties in the security and condition setting of the offline stage. For example, setting the length of time limit for offline and setting the time limit for returning It has a lot to do with anti-money laundering and security.

"You can monitor the payment process, but if the device is offline for a long time and tens of thousands of dollars are packed in multiple digital wallets, turning on airplane mode will If you are offline, you have to pay and launder money everywhere. If there are no restrictions, you can even be offline for more than ten years, and you will not be able to reconcile your accounts for a long time. If the setting time is too short, it is easy to accidentally damage it in reality. Some people leave or go abroad temporarily, and it will become invalid after being idle for a period of time, which will damage the authority of legal currency. After a long period of time, I used Pengpeng to exchange several mobile phones. If there were many offline transactions, how to trace them? Some transactions are legal, and some transactions are illegal. After a long period of time, the consumer goods have been consumed. How can I recover them? " He said.

Wang Zhicheng said: "Ideally, I want to track it through digital currency, but once it is allowed to be offline, or even offline for a long time, where can I go to chase it? ”

『撒』 What is blockchain? Explanation of blockchain technology

Blockchain is distributed data storage and point-to-point transmission. , consensus mechanism, encryption algorithm and other new application models of computer technology. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database.

At the same time, as a Bitcoin The underlying technology of the currency is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate next A block.

Blockchain is a public data list, and each record in it is called a block. These blocks are connected together like a chain to form a blockchain. Just like the idiom Solitaire, there must be some connection between adjacent words to form a word chain. The same is true for blockchain, but the connection between blocks is much more complicated.

(7) Wanxiang Blockchain Virtual Currency Extended Reading

Blockchain technology innovation does not mean speculating on virtual currencies. We should prevent the use of blockchain to issue virtual currencies. Speculating on air coins and other behaviors. At the same time, it should be noted that the blockchain is still in the early development stage and needs to be implemented in terms of security, standards, supervision, etc.To further develop and improve.

The general direction is not wrong, but it is necessary to avoid rushing in and duplicating construction, and to open up the imagination space of the blockchain in orderly competition. China has a good foundation in the field of blockchain. Some large Internet companies have already laid out their plans. The talent pool is relatively sufficient and the application scenarios are rich. It is fully qualified to achieve a leading position in this new track.

From a larger perspective, human beings can develop civilization because they have achieved effective cooperation among large-scale groups of people. The "invisible hand" explained by Adam Smith also realizes the division of labor and cooperation in human society through the market mechanism.

From this perspective, blockchain has greatly expanded the breadth and depth of human trust and collaboration. Perhaps, blockchain is not only the next generation of Internet technology, but also the next generation of cooperation mechanisms and organizational forms.

『8』In addition to being used in virtual currencies, what other aspects can blockchain technology be used in?

In addition to being used in virtual currencies, blockchain technology can also be used in the financial field and digital Currency and securities transactions, 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.

『九』 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".

『Shi』What exactly is blockchain? Blockchain is virtual currency

Let me tell you about blockchain in layman’s terms, no. Do you need to use any advanced professional terminology? Because that is 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. IfYou four ABCD are going to play mahjong. Who said 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 the winning and losing of each game, no matter what method they used, whether it was brain memory, video recording, or notes. Well, the more they fight, the more they can reflect the immutability, decentralization, distributed accounting, and consensus of the blockchain...

At this point, you Now you basically understand 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 currencies have overturned traditionalTraditional finance can easily lead to 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 dynamically stable and decentralized cloud-like computing resource provision channel.

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. For example, the relationship between blockchain and digital currency is as follows:If you build a dapp application mall on a certain chain, you can issue a token related to this mall.

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.

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, for example, when playing Douyin, each of us requests the Douyin server, and the Douyin server gives us the video. 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.It's BTC

Blockchain is a new type of Internet application technology, which uses emerging technologies such as distributed storage, cryptography, smart contracts, and consensus algorithms. It can be said to be an evolution of existing Internet protocols. An innovative new data transmission method. 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.
