If a person's moral character is not good, then it doesn't matter how good he is. How to use it?

4. Which is more important, IQ or EQ?

Generally speaking, EQ represents perceptuality, and IQ represents rationality. As far as managers are concerned, EQ is more important than IQ, because In the management process, it is more about dealing with people, and the contact between people pays more attention to emotional communication, but this does not mean that IQ is not important. Managers' decisions and system formulation all need to have a rational basis. The abilities of managers caused by emotional intelligence are mainly reflected in three aspects: first, communication ability; second, decisiveness; and third, willpower.

To answer this question, pay attention to combining theory with practice. You should not only talk about MBA theory, but also give examples. Next, let’s talk about your views on what society thinks of MBAs. Just a few years of MBA study cannot train an ordinary person who does not study and think seriously into a future business leader, but I believe that an MBA can train a person who is committed to becoming a future business leader. People who work hard to learn to think and actively exercise in practice are more likely to become future business leaders.

8. The greatest pressure you have ever encountered at work

When asking this type of question, the examiner wants to know your ability to withstand it. First, give an example of how you move forward bravely, persevere, never give up in the face of pressure, and have your own way of resisting and releasing stress. If the question is not originally a big one, but you exaggerate and answer it as the greatest pressure, it means that you are not able to bear it, so you should be careful when answering such questions.

⑶ What is the popular explanation of blockchain

What is the popular explanation of blockchain

What is the popular explanation of blockchain? Blockchain is currently a hot topic The topic of blockchain is developing faster and faster in China, but many people still don’t know what blockchain is? Now I will give you an easy-to-understand explanation of what blockchain is!

BlockchainWhat is a popular explanation 1

Blockchain is generally a decentralized distributed ledger database. The advantage of this distributed ledger is that buyers and sellers can trade directly without any intermediary. There are backups, so even if you lose this copy, it will not be affected.

Suppose you have a ledger at home, and your parents give you your salary and ask you to record it in the ledger. You misappropriated more than ten yuan privately because of your greed, and no one else knew about it. But the way to solve the problem with blockchain is to keep accounts with the whole family. Not only you are keeping accounts, but your father, mother, brother, sister, younger brother, sister, etc. are all keeping accounts. They can all see the general ledger, and you It cannot be changed, and neither can others.

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc.

Popular explanation of what blockchain is 2

Common questions in blockchain engineer interviews

What do you think the block in blockchain technology means?

The blockchain consists of information about all financial transactions. A block is nothing more than a list of records. When these lists are combined together, they are called a blockchain. For example, if an organization has 100 ledgers, their combination is called a blockchain, and a single ledger will be considered a single block.

Why is blockchain a trustworthy approach?

There are many reasons to trust blockchain. The first reason is that it is compatible with other business applications because it is open source. Secondly, it is secure because it was developed for online transactions, so the developers pay special attention to its data synchronization while keeping it safe. Because the type of business it holds is unrelated, it is easy to consider distinguishing chains when choosing.

How much do you know about blockchain?

This is a technology that was actually designed for Bitcoin and later heavily promoted for the multiple benefits of monitoring and recording all financial transactions on the network. This is a trusted method that is currently being used by many organizations. Since everything is secure and open source, it is easy to gain trust in the long run.

Utilizing blockchain in an organization, if there are specific technical requirements for that network?

No specific conditions of use. However, the network must be a peer-to-peer network under the relevant protocol. It literally just validates new blocks and helps organizations stay in sync without having to invest in third-party applications.

What is encryption? What is its role in blockchain?

Data security is always very important. Encryption is basically a way to help organizations secureMaintain data security. In this technique, data is encoded or altered to some extent by the sender before being sent to the network. Only the receiver can know how to decode it. This practice is very useful in blockchain because it increases the overall security and authenticity of the block and helps ensure that the block is secure.

What types of records can be saved on the blockchain? Are there any restrictions?

There are no restrictions on any type of records in the blockchain approach. Currently, many organizations around the world are using this approach, and the fact is that medical transaction records, organization-related events, administrative activities, transaction processing, identity management, document records are all common record types that can use blockchain. And record keeping is not limited to these applications..

What is double spending?

This is one of the main issues related to digital currencies. In practice, this is a condition of passing a digital certificate, since the card can be used multiple times through a digital file that is often easily cloned. It only leads to inflation and the organization has to bear huge losses. A major technical goal of blockchain is to eliminate this approach as much as possible.

Explain the importance of blind signatures and how they are useful?

It is actually a form of digital signature, an important part of cryptography, where all information is blinded until it is actually considered or signed. This is a proven method often considered in different privacy-related agreements between the author and the signatory. Digital currency design is one of the most common examples.

What is key sharing? Are there any benefits to blockchain technology?

As we all know, security issues in digital transactions are very important. Key sharing is a similar approach. In blockchain technology, this is a method of dividing keys or personal information into different units and sending them to network users. The original information can only be merged if the participant who distributed the key agrees to be merged with other participants. It can provide various security-related benefits in blockchain technology.

What organizations can use blockchain technology?

This method can be considered as commercial class without strict upper limit. In fact, almost all businesses are doing or online financial transactions that require them to successfully complete the implementation process. Large enterprises, financial institutions, private enterprises, government departments, and even defense agencies can easily trust this technology.

What is the difference between a blockchain ledger and a general ledger?

First of all, the main difference is that blockchain is a digital ledger that can be easily decentralized. This method is far less likely to go wrong than a regular ledger. Normal books are written by hand or by hand, blockchain does all the tasks automatically. You just need to configure it the right way and follow all the guidelines.

What is softSplit?

Blocks in the ledger are included in a way that builds the longest chain, i.e. the chain with the greatest cumulative difficulty. A fork is a situation where there are two candidate blocks competing to form the longest blockchain, and two miners discover a working problem and fail to synchronize with each other within a short period of time. Causes network fragmentation because some nodes get blocks from miner #1 and others get blocks from miner #2. Forks are usually resolved in one block because the probability of this happening again becomes very low as the next block comes out so soon there is a new longest chain that will be considered primary.

⑷ During the interview, what should you do if the interviewer deliberately makes things difficult for you?

For companies, the purpose of interviews is to recruit suitable people, except for individual cases. , many questions seem to be difficult, but they are actually testing the candidate's adaptability and flexibility. Therefore, you need to prepare some related similar questions before the interview, so that you can not panic on the spot.

1． "Brain teaser" questions

For example: Why are sewer manhole covers round?

Comments: Many job seekers feel that the interviewer has unclear intentions when asking "brain teaser" questions, and some even think that the interviewer is deliberately trying to embarrass people. The reason is that job seekers cannot prepare in advance for such questions. But we can see that, except for interviews for recruiting development and design positions, in fact, in most interviews, even if there are so-called brain-teaser questions, there are only a small number of them, and they mostly appear at the end of the interview. The interviewer does not ask for standard answers when asking these questions, but only intends to test the applicant's knowledge reserve, logical thinking ability and psychological endurance. Therefore, instead of complaining, job seekers should accumulate and practice more in these aspects and show full confidence during interviews.

2. Personal connections at work

Comment: If the applicant is not from the local area, but the interviewer needs to know who he knows locally by filling in a report or asking questions, etc., he probably wants to know from a side perspective. its stability. In addition, any position that requires external work now requires job seekers to have certain network resources, such as sales, marketing, reporters and editors, and even finance, accounting, etc. When the job seeker understands the purpose of the interviewer asking this question, he will not feel uncomfortable for no reason.

3. Ask "Do you have any questions to ask?"

Comments: A previous survey by 51job showed that more than 97% of interviewers will ask the above questions at the end of the interview. Many job seekers know that the interviewer will have a "last question", but they are often speechless on the spot or worry about making a mistake afterwards. In fact, just as the teacher asks the students if they have any questions at the end of a class, the interviewer's "last question" is mainly to examine the candidate's preparation before the interview and the degree of concentration during the interview. After all, some questions may arise during the interview. Things that will not be actively mentioned by the interviewer but are very important, such as holidays, salary, promotion, etc. As for what to ask and how to ask the "last question",Applicants can detect something from the previous interview process, but it is not very likely to rely on the "last question" to turn things around.

4. Advantages, Disadvantages, Personality and Temper

Comments: Regarding the issues of advantages, disadvantages, personality and temper, the advice to job seekers is: stay relatively honest. After all, the interview is a game process, and being glib and clueless is not advisable. As for the interviewer, it is of course important to examine a person's attitude and accomplishments, but it is not realistic to rely on a 30-minute interview to identify a person's strengths, weaknesses, personality and temperament. Instead of questioning candidates in order to lower their salary, it is better to consider how to maximize the value of a potential employee and avoid weaknesses to truly save costs for the company.

5. Personal finance-related matters such as income and expenses

Comment: As an interviewer, it is necessary to understand the income of the applicant's previous job, but it is a bit too much to care too much about other personal income and personal expenses. Some job seekers will deliberately lower their salary because they are worried that the interviewer will want to know too much about their personal income. However, everything has two sides. Job seekers can actually express a positive side to the interviewer: for example, even though their salary in their last job was low , but it does not mean that you have poor abilities. You are fully qualified for a new job with a higher salary; for example, a large personal expense is what drives you to work hard. You are willing to work hard in your new job and believe that you can rely on your personal abilities. Get more income. I believe that no interviewer cannot understand and accept a job seeker's reasonable explanation.

6． Regarding previous work experience

Comment: Work experience and experience are a very important part of the interview. As a job seeker, you should answer carefully and skillfully, so as not to reveal the secrets of the previous company, and to be able to To demonstrate your work ability, you must also prevent the interviewer from maliciously "borrowing your brain." For some of the interviewer's questions that may appear to be "borrowing brains", the job seeker can first respond generally with vague language. If the interviewer repeatedly asks for details, the job seeker can ask the interviewer appropriate questions instead of just pandering to them. In addition, netizens reported that some interviewers like to ask applicants to compare their previous and previous jobs. This is actually the interviewer's way of examining the netizen's job-hunting motivation and awareness of the new job. At this point, candidates don’t need to stick to the past—and avoid the embarrassment mentioned above—but should focus more on new jobs in the future.

Objectively speaking, the above questions are not too "excessive" in themselves, but we have to deny that there are some interviewers in the market whose business skills are not up to standard, and some companies have biased employment concepts. Negative situations that can affect the reputation of the entire industry. Therefore, while we encourage job seekers to take any interview seriously, we also call on our companies to pay enough attention to any employee when recruiting, even if it is a hierarchical level. (End)

⑸ What types of questions will be asked in MBA interviews

Let me tell you who has served as an interviewer for an MBA in a business school. In fact, interviewers do not have a fixed routine. Generally, we will hold a "meeting meeting" half an hour before the interview to talk about the specific process. This cannot be changed.

⑹ Popular explanation of what blockchain is

Question 1: What is blockchain? Can you explain the principle of 10-point blockchain in plain language: decentralized distributed accounting system
The core of blockchain technology is that all currently participating nodes jointly maintain transactions and databases, which enables The transaction is based on cryptographic principles rather than trust, allowing any two parties that reach an agreement to directly conduct payment transactions without the participation of a third party.
?
Technically speaking, a block is a data structure that records transactions, reflecting the flow of funds for a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash hash formed by the previous block, and random number. Transaction information is the task data carried by the block, specifically including the private keys of both parties to the transaction, the number of transactions, the digital signature of electronic currency, etc.; the hash formed by the previous block is used to connect the blocks to realize the past The order of transactions; random numbers are the core of transaction completion. All miner nodes compete to calculate the answer to the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for update, thus completing a transaction.
1.1 What is Blockchain
Blockchain (BlockChain) refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes participating in the system to associate and generate a series of data blocks (blocks) using cryptographic methods. Each data block contains all the information exchange data of the system within a certain period of time, and generates The data fingerprint is used to verify the validity of its information and chain to the next database block.
?
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. Behind all systems there is a database, which is a big ledger. Then who will keep this ledger becomes very important. At present, it is whoever owns the system who keeps the accounts. Each bank’s account books are kept by each bank, and Alipay’s account books are kept by Alibaba. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are new transaction data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write the recorded content to the ledger, and Send the contents of the ledger during this period to all other people in the system for backup. In this way, everyone in the system has a complete ledger. Therefore, this data becomes very safe. A tamperer needs to modify more than half of the system node data at the same time to truly tamper with the data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system.
?
1.2 Why is there blockchain innovation?
Human beings need to communicate during their activities, and communication is based on information. In the past, information circulation was not convenient enough to satisfy market participants. There is a demand for information, so intermediaries and centers are born. This centralized system has the disadvantages of high cost, low efficiency, value dispersion, "information islands" and insecure data storage.question. However, due to technical and environmental factors, this system continued to operate for many years until the emergence of the Internet. The starting point of the first generation of the Internet is the TCP/IP protocol, which is an open code that implements a unified format for peer-to-peer transmission of information by all nodes on the network, and brings the basic values of freedom and equality required by a global unified market into programmed, protocol-based, and reliably Execution. The Internet eliminates low-value, high-cost intermediate chains and achieves low-cost and high-efficiency global information transmission in a decentralized manner.
?
However, the first generation of the Internet did not solve the problem of information credibility. Activities that can be decentralized on the Internet must be activities that do not require credit endorsement, and activities that require credit guarantee must be activities involving centralized third-party intermediaries. Therefore, Internet technology that cannot establish global credit has encountered great obstacles in its progress - people cannot participate in any value exchange activities on the Internet in a decentralized manner. To realize value exchange, people still need third-party intermediaries based on credit (such as banks, clearing agencies, exchanges). The global centralized credit system still has problems such as high operating costs, low efficiency, and vulnerability to attacks and damage. For example, each country's legal currency has different credit values and incompatible clearing systems, which adds a lot of cost to global trade.
?
Therefore, what the second generation Internet must break through is: how to establish global credit in a decentralized manner? Let...>>

Question 2: What is blockchain? What does it mean in layman’s terms? What is China’s attitude towards blockchain? What can blockchain do? Blockchain, a great technology that accompanied the birth of Bitcoin, is currently being used in the financial field to significantly reduce transaction costs and improve efficiency, which is enough to excite Wall Street. However, this is just the tip of the iceberg. Its potential applications are very broad and will subvert every aspect of our lives in the future.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. One of the most basic characteristics of Bitcoin is decentralization. In recent months, financial giants have gradually begun to pay attention to Bitcoin's technology and used it in non-monetary fields, such as stock trading, election voting, etc. (1) Art Industry
Artists can use blockchain technology to declare ownership and issue numberable, 100% edition works in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
(2), Real estate industry
Use blockchain technology to solve various problems faced by everyone involved in real estate, including the naming process, land registration, agency intermediaries, etc.
(3), Insurance Industry
GoldThe financial industry has always been the most sensitive to advanced technology. Traditional banking and securities industry giants have been involved in the booming blockchain venture capital investment since 2014, with total global investment reaching US$1 billion within two years.
(4) P2P wallet
Personal assets can be traded through this P2P wallet in the future without going through any central institution, such as Bitcoin.
Most blockchains are in their infancy, mainly overseas. There are very few good domestic blockchain projects, so it is not recommended for any non-professionals to invest in blockchain projects. If you are very interested in blockchain technology and have a technical or financial background, it is recommended that you consider starting a business in this area. In terms of the blockchain protocol system, the lowest layer is the underlying technology of the blockchain, including the technical protocols of the blockchain, as well as some platform routing and basic algorithms; in the middle layer, some application interfaces and some credentials must be solved Issuance and verification, including some industry platform services, big data analysis, etc. This is a very rough classification, and there should be more detailed classifications; the top ones are some applications of blockchain, including finance Some applications and some applications in other aspects, the Internet of Things and so on.
Introduction to Bubi Blockchain
Bubi Blockchain has been focusing on the research and development and innovation of blockchain technology and products since its establishment. It has a number of core technologies and has achieved substantial results in many aspects. Radical innovation has resulted in a number of core technological achievements, such as: mathematically provable distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, and interconnection technology between heterogeneous blockchains. wait. On April 25, "Gege Points" introduced the concept of blockchain into the points system, jointly opened it up with multiple parties, issued and redeemed points, and promoted the circulation of points. Each cooperative institution can jointly participate in transaction verification, ledger storage, and real-time settlement; the third-party payment platform of the enterprise points issuer makes the entry and exit of points more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open value circulation network with decentralized trust as the core, allowing digital assets to flow freely.
A simple understanding of blockchain is a technology at the bottom of Bitcoin, which is also a peer-to-peer electronic cash system that can realize peer-to-peer value delivery. We should distinguish between Bitcoin, Bitcoin blockchain, blockchain and blockchain. Blockchain technology and other concepts. In countries with relatively developed finance in the past, finance and blockchain technology have a long history, and the legislation of digital currencies and blockchain networks is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own teams and conceptual technologies. Slowly, banks in various regions are also participating in digital currency discussions. The application and support of this technology are not only that. The influence of blockchain on enterprises is also huge. For larger domestic enterprises, Bubi Blockchain is also used in various fields such as equity, supply chain, points, etc.In this field, major domestic financial institutions and enterprises have taken a fancy to the value of the new industry and developed their own blockchain platforms. Blockchain has instantly become a new domestic innovative industry. In terms of overseas internationalization, the United States has already obtained 15 blockchain patents at the end of last year compared to China. Blockchain financial applications are entering a new stage in an all-round way. Various applications will become more and more in-depth, and related changes will also become more and more profound. It has attracted more and more attention and will form a huge new trend... >>

Question 3: What is blockchain technology? What exactly is blockchain? What is blockchain? 1. Data blockchain is an important concept in the Bitcoin financial system. It records transaction record data on the entire Bitcoin network, and these data are shared by all Bitcoin nodes. Through the data block, we can query each transaction record. A look at the history of Bitcoin transactions. 2. Example: There are three persons A, B, and C. All funds of A and B are kept by C. And every financial transaction must be recorded by C. Now assume that A and B each have 1 million in custody of C. Then: A spends 80,000 yuan to B, then C's account book record will subtract 80,000 yuan from A's name, and add 80,000 yuan to B's name. If B transfers 50,000 yuan to A, C will add 50,000 yuan to A's name and subtract 50,000 yuan to B's name in the account book. A spends 50,000 yuan to B, then C's account book record will subtract 50,000 yuan from A's name, and add 50,000 yuan to B's name. 3. The role of the data blockchain is similar to that of C’s account record book. It records the user’s ownership of Bitcoin and the records of all users’ Bitcoin transactions. It’s just that this “account record book” is recorded by the mining software of every Bitcoin miner on the network. If a Bitcoin transaction is confirmed by the data blockchain, the relevant information will be recorded in the data blockchain. Bitcoin’s “account record book” is called the data blockchain. All data blockchains on the network form Bitcoin’s distributed network database system. 4. The essence of data blockchain technology is a decentralized and distributed structure of data storage, transmission and certification methods. It uses data blocks to replace the current Internet's dependence on central servers, so that all data changes or transaction items are recorded. On a cloud system, the self-certification of data during data transmission is theoretically realized. In a far-reaching sense, this transcends the traditional and conventional information verification paradigm that relies on a center and reduces the cost of establishing global "credit." This point-to-point verification will produce a "basic protocol", which is a new form of distributed artificial intelligence and will establish a new interface and shared interface between human brain intelligence and machine intelligence.

Question 4: What is blockchain: This explanation of blockchain is more understandable. Blockchain refers to a technology that collectively maintains a reliable database through decentralization and trustlessness. plan.
In layman’s terms, blockchain technology refers to a method for all people to participate in accounting.Mode. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important. Currently, whoever owns the system keeps the accounts. Tencent keeps the accounts of WeChat, and Alibaba keeps the accounts of Taobao. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write his recorded content into the ledger, and record this Within a period of time, the contents of the ledger are sent to all other people in the system for backup. In this way, everyone in the system has a complete ledger. In this way, we call it blockchain technology.
Blockchain technology has become the darling of the financial community in China and has become a hot topic. Domestic Puyin Group has launched Puyin, a tea-based digital currency.

Question 5: Explain in an easy-to-understand manner what blockchain is. Blockchain can be understood as a database system in a sense. The development of blockchain can be divided into 1.0 and 2.0
1.0 is represented by Bitcoin, and its main application is virtual currency or digital currency application. The blockchain at this time can only be used for simple digital currency transactions.
2.0 is represented by the now popular ethereum (Ethereum) and the upcoming hyperledger. The blockchain at this stage can not only meet the corresponding digital currency transactions, but also use smart contracts to customize currency or asset transactions. If we use the database analogy, the emergence of smart contracts can be understood as allowing users to define functions or stored procedures in the database and call and execute them.
Different from traditional databases, the blockchain introduces consensus mechanism, incentive mechanism, p2p (network), hash and other specific elements, making it open, decentralized and non-tamperable. characteristic.

Question 6: What is blockchain? Can anyone explain it in simple terms? Blockchain is the underlying technology of Bitcoin. It is like a ledger that records all transactions. It is decentralized. What is decentralization? For example, when you buy something on Taobao, you place an order and pay in Alipay. Alipay will not transfer the money to the seller until you receive the goods. Alipay is the third party in that center. Without it, it means decentralization, just like buying things offline. If you pay with one hand and get the goods with the other hand, there is no third party.
The blockchain itself is a series of cryptographically related data blocks generated.
Look carefully to see if it looks like a ledger. The pieces one by one are blocks, and connected together they are the blockchain.
Many companies are developing this technology, and so is our company. Its prospects are incredible ***of. For details, you can go to our official website and hope to adopt it, thank you

Question 7: What is blockchain technology? What is blockchain? How to explain the concept of blockchain? People in each industry have different understandings, and relevant explanations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are getting bigger and bigger. If we want to understand this technology, we must have an in-depth understanding of reality.
In the past six months, the concept of blockchain has gradually become popular in China, and a blockchain whirlwind has taken off in the financial circle. Blockchain has attracted the attention and favor of more and more people in the industry due to its unique technical advantages. Blockchain technology, which is decentralized (or multi-centered), highly transparent, cannot be tampered with, and has no single point of failure, is entering the field of vision of financial institutions and enterprises. It has at least been used in digital currency, payment exchange, registration and settlement, Digital assets, traceability and anti-counterfeiting, supply chain, Internet of Things and many other fields have moved from theoretical discussions to practical applications.
"Blockchain" was first introduced with "Bitcoin" released in early 2009. Blockchain has become the basic protocol and technical application for the launch, recording, and circulation of Bitcoin. Although Bitcoin has been controversial since its inception and cannot even be regarded as a "currency" by governments and monetary authorities, the blockchain technology used in Bitcoin has been recognized by governments, including governments and monetary authorities. extensive attention.
Why has blockchain become a rapidly heating up hot technology and topic?
The most important of these may be that the launch of Bitcoin based on blockchain technology has opened up a new relationship with traditional society ( The exploration and attempt of new technologies and rule systems such as Internet user identity verification, wealth confirmation, transaction records, notarization and verification, which have little connection with offline) and are completely applied to the online world (online), provide people with the opportunity to adapt to the Internet society. Development provides alternative paths and unlimited imagination.
Judging from its application in Bitcoin, blockchain is a set of new network blocks (BLOCK, also called communities) formed by combining encryption technology with the Internet. Bitcoin configuration, netizen identity verification, and Bitcoin (value) confirmation formed by mining, Bitcoin transaction records, and extended encryption of Bitcoin cross-block flow (value transfer) (added block and transaction time identification, etc. Internet protocol rules and accounting (Ledger) system including block chain, full encryption, mutual authentication, etc., including factor) registration and verification. Precisely because Bitcoin is not a substitute for offline legal currency, but is issued and managed by non-legal currency authorities, mainly imitating the model of gold, and is completely new and decentralized protected and supported by basic Internet protocols and strict encryption technology. Internet currency (virtual currency) has thus formed a new set of currency rules and systems that are different from and not subject to real social laws, and can be bought, sold or exchanged with legal currency.Change. It has been more than 8 years since Bitcoin was launched. There has been no record of funds or user information being stolen. Its security has been verified, and its efficiency and cost of fund settlement also have obvious advantages. This has made people's confidence in the blockchain technology used in Bitcoin continue to increase, and people have become more and more aware that although blockchain is a technology and protocol pioneered and applied by Bitcoin, the blockchain Chain is not the same as Bitcoin, and its application is by no means limited to Bitcoin. The application of blockchain can be decentralized or centralized; it can be a public chain model or a private chain model. Therefore, after Bitcoin, blockchain technology is also constantly developing and innovating, and constantly exploring new application fields, especially in the financial field.
The reason why blockchain is valued highly by more and more people is because the development and widespread application of the Internet have caused more and more economic exchanges and transaction activities to be conducted online, and the online world (or online world) society) is rapidly expanding, enriching and active, and online transactions must solve the efficiency and security protection issues of the parties' identity verification, value verification, transaction records, inspection and verification, etc., and require strict intermediaries and agreements (rules or constitutions). In this regard, traditional thinking and customary practices are to follow the development trajectory of the transfer of offline transactions to online and push the common rules and practices of the real (offline) society to the online (network) society. However, in practice, it is increasingly It is difficult to adapt to the needs of online transactions.
For example, for the identity verification of the parties, the natural choice is to use the information on the identity documents protected by the laws of various countries as the basis, and then add account or transaction passwords, as well as facial recognition, iris, fingerprints and other biometrics to conduct online transactions. Verification, but this method first makes the citizen identity information in the cross-border interconnected online world subject to the administrative jurisdiction of real society... >>

Question 8: Easy to understand Explain clearly what is blockchain. The English name of blockchain is Blockchain. Block literally means block, block, and chain means chain, chain. Therefore, together they are translated into blockchain.
1. Use cryptography technology to encrypt and decrypt so that records cannot be tampered with. Common blockchain encryption methods include hash algorithm, RSA algorithm, elliptic curve algorithm, etc.;
2. The huge amount of calculation needs to be supported by a reasonable reward mechanism. Because every transaction must be recorded, Bitcoin’s blockchain has more than 60 gigabytes so far. Every new transaction requires confirmation of the information related to the trading account to ensure that the transaction is valid. The huge amount of calculation requires a computer with powerful computing power to complete.
In order to encourage the participation of powerful computing power, Bitcoin provides two rewards: one is to issue a certain number of Bitcoins to these computers every day; instead, all transfer fees are awarded to these computers. (These computer majorsThe term is "mining machine", and the person who holds the mining machine is called "miner". )
Biying China is working hard on asset digitization and launched the digital currency crowdfunding platform Biying China.

Question 9: What is the so-called "blockchain"? Blockchain itself is a tool called decentralization and trustlessness. For example, when you graduate from university, the current practice is to have a certificate recognized and issued by an authoritative agency as your certificate. This setting is more troublesome, because this is a piece of paper, and paper can be forged, so there will be various gaps. The issuing authority is also a person, and there will be various gaps in the middle. As long as it is related to people, whoever There are various possibilities related to media. The blockchain provides a great opportunity. As soon as you graduate, you will have a record on the blockchain. No one can change this record. This thing exists objectively. You, as a physical existence , and then as a data existence, the blockchain was born. In this case, anyone who wants to check where you graduated can easily solve the problem. This is similar to the big data often involved in social networking (WeChat) and payment platforms (Alipay, Yibao).

Question 10: What does blockchain mean? Regarding blockchain, I think you have already seen the concept on the Internet. Let me explain it based on my understanding!
First, let’s talk about its characteristics: 1. Openness and transparency 2. Decentralization 3. Anonymity 4. Information cannot be tampered with, eliminated 5. No trust cost
Blockchain is like a public ledger , everyone has the right to record and read, and everyone will jointly supervise to ensure its accuracy, and the recorded content will be permanently saved, and can only be added but not deleted! However, as the number of blocks continues to increase, costs will increase and efficiency will decrease. (I’m not sure whether technology can be used to make up for this. I hope someone who understands technology can point it out.)
Blockchain is divided into public chain, private chain, and alliance chain. Public chain: accessible to everyone, everyone has read and write permissions, completely open, transparent and decentralized. Private chain: Open to individuals or institutions, in which the owner of the private chain can set various permissions to make it partially centralized. Alliance chain: Open to specific organizations or groups, it is also "partially decentralized". According to the ledger at the beginning, members can view and transact, but cannot record and confirm bills, or require permission from the alliance. (The latter two do not have cost and efficiency issues)
Regarding blockchain, countries have begun to recruit talents in this area. For this, you can search online for "Central Bank Recruiting Digital Currency R&D Personnel". In addition, you can increase your understanding of blockchain by understanding its existing applications. What we usually refer to generally refers to public chains. Currently, those used abroad include Bitcoin, Ethereum and other domestic blockchains. Chain
1. Open and transparent: every piece of data is verified by everyoneYes, everyone can view it at any time.
2. Decentralization: For example, when we shop on Taobao, we conduct transactions through the intermediary Taobao, and blockchain allows both supply and demand parties to directly contact each other for direct transactions through blockchain technology.
3. Anonymity: No personal privacy information is required to complete transactions on the blockchain, only your unique alphanumeric signature is required.
4. Information cannot be tampered with or deleted: Once the data has been verified and recorded, no one has the authority to modify it, let alone delete it!
5. No trust cost: The trust crisis in reality will not appear in the blockchain. Transactions in the blockchain do not require you to trust the other party. Only when both of you have enough "digital assets" to trade can it be carried out, and Under the supervision of the entire network, transactions will not be broken. If you have no idea about the cost of trust, just think about how many intermediaries there are in your city, or just think about Jack Ma, and you will know how big the cost of trust is.
I am still learning more about blockchain. I am Li Ailin. If you have any questions, you can discuss and learn together!
