❶ What is the knowledge related to blockchain? Can you please help me explain it?

Shared from District View Network
1. Basic concepts
There are many definitions of blockchain. Here, I will analyze the opinions of various schools, simplify the complex and adopt a more easy-to-understand explanation:
English name of blockchain: Blockchain is also called Block chain. It is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.
Blockchain is essentially a distributed database, a series of data blocks generated using cryptographic methods. Each data block contains information about a network transaction, which is used to verify the validity of its information. (anti-counterfeiting) and generate the next block.
2. Working principle
The core potential of blockchain lies in the characteristics of distributed databases and how it contributes to transparency, security and efficiency.
In the past, institutions used centralized databases to support transaction processes and calculations. Control of the database rests with its owner, who manages access and update permissions to the database, limiting transparency and scalability and making it difficult for outsiders to ensure that data records have not been manipulated.
At the same time, due to technical limitations, distributed databases are basically impossible to implement. But with advances in software, communications and encryption technology, a distributed database across an organization is now possible. Blockchain gradually emerged.
3. Core ideological connotation
The basic idea of ​​blockchain is to establish a network-based public ledger (data block), and each block contains information about a network transaction. All participating users in the network jointly record and verify accounts on the ledger. All data is open and transparent and can be used to verify the validity of the information. In this way, the authenticity and non-tamperability of information can be guaranteed at the technical level without the need for a central server to act as a trust intermediary.

❷ What should "blockchain" be translated into professional English?

Answer for you
Block chain
First of all, distinguish The main function of the blockchain is to store information. Any information that needs to be saved can be written to the blockchain and read from it, so it is a database.

❸ Zihang talks about currency: Newbies in the currency circle don’t even know what “blockchain” is

First of all, I believe that before everyone learns about blockchain, You’ve heard of Bitcoin first, right? Because we all know that the first people to hold Bitcoin made money!

But one point of view is wrong: What point of view? Many people believe that Bitcoin is the blockchain. In fact, Bitcoin is just a type of blockchain asset, and it is the earliest blockchain asset. The concept of blockchain comes from Bitcoin. The reason why Bitcoin can be so arrogant isIt exists independently enough and does not rely on any organizational structure. That is because the underlying layer is supported by blockchain technology.

Just like our mobile phones can run, the bottom layer is supported by Android or ios system. So what kind of technology is blockchain? Why is it so powerful? Can make Bitcoin so valuable! The English name of blockchain is block chain, and block means block. You can imagine that if you fall or bump into something, you may have bruises, right? The blocks in the blockchain contain some The data block of transaction information, something, may have a bruise, right? The block in the blockchain contains some data blocks of transaction information, and the chain in the blockchain connects the data blocks. , this is like a big ledger. Anyone who uses this blockchain ledger can directly query any transaction information arranged in order, and it is difficult to tamper with. So how does it do it?

Let’s give a simple example based on local materials: There are now a total of 100 readers, who are linked through the Internet to form a blockchain network system. Please pay attention! We are not reading this article now, but a blockchain network system. In this system, I ask one of the people, say this person is called panda, to borrow 10 yuan, and then panda transfers the 10 yuan to me in the network system. Then my account or wallet increased by 10 yuan. As for panda, who lent money to Bibi, his account lost 10 yuan. After this transaction is completed, other people in our blockchain network system, after seeing it, will take a small notebook and record the matter. My account will increase by 10 yuan, and panda's account will decrease by 10 yuan.

That’s not right, then what are you doing when you are full and have nothing to do? Why should we record these small and medium-sized "bad things"? It’s because the network system will pay wages to those who participate in recording. As long as she records it once, the system will automatically reward tokens that are common in the network system. As long as there is money, everyone is willing to do anything. In reality, there are actually countless individuals in a blockchain system, which means that our group not only has only 13 people, but they don’t know each other yet, but they can all communicate with each other on the system chain and record them in the blockchain in order. For this transaction in the network, if one day I want to default on the debt and no longer plan to pay back 10 yuan to panda, then I must convince more than 51% of the people in the blockchain network system to delete this record or tamper.

If it were replaced by real-world computing power, it would be almost impossible and would require huge costs. This is the characteristic of blockchain technology - decentralized collaboration, transaction data is difficult to tamper with, and transaction information is transparent and queryable. Its main function is to solve two problems that are difficult to solve on the Internet - one isTrust, the other is value delivery.

The so-called trust, according to the above scenario, is that I may default on the loan and take the money and run away; the value transfer is: my borrowing account should increase by 10 yuan, while the panda account becomes -10 Yuan money exchange. Then we may have questions again, isn't Alipay and WeChat payment solved now? Wouldn’t it be enough to just confirm the account and transfer the money directly and send a red envelope? Yes, Alibaba and Tencent exist based on solving these two problems. but! Thinking about it from another perspective, if a mere blockchain technology can solve these two problems now, can huge and complex institutions like Alibaba and Tencent be abandoned?

Rebuilding a new network system to apply it to more fields is on the way.

Because, the final conclusion is: this technology builds the value of Bitcoin, then this technical logic can also be used in many other fields. Maybe one day you will be happy to discover - Huh? I am now using a product from a certain blockchain technology company! ? Just like many years ago, one day you unknowingly used QQ and started to learn to watch videos and play games online. Having said that, what does it mean that Bitcoin is an early asset of the blockchain? Why does it add value? According to the scenario mentioned above, the so-called tokens are the tokens issued by the system to everyone in the group by participating in accounting. These tokens are blockchain assets. (The behavior of everyone participating in bookkeeping is commonly known as mining.) Bitcoin itself is the value token of the Bitcoin blockchain network system

Then why is it Will it add value? Because its quantity is limited, the number of issuances is determined at one time from the beginning of the establishment of the network system and will never be issued additionally.

So, in the future, the more people participate in accounting in a certain blockchain network, the number of people who get it will gradually decrease, and value-added will become inevitable. This is like Alibaba's early stocks. After the Alipay application is launched, the more people participate in using it, the more it is needed, and Alibaba's stocks will inevitably increase in value.

Of course, there are currently many projects applying blockchain technology, but most of them have not found a landing scenario. However, the more people believe that a project created using blockchain technology will be used in the future. If necessary, the price of the tokens of this project will be pushed up. Therefore, there are far more investment opportunities in blockchain assets than in the ordinary stock market. If you invest in a value project, then it may skyrocket to over 130,000 per Bitcoin a few years ago, to a little over 40,000 now. In other words, you don’t need to consider any investment opportunities in other varieties. A few years ago, if you bought Bitcoin with your eyes closed and then ignored it and just went about your own business, the return on this investment would be 100 times in one year.

Profit! How much is that right? The opportunities in this industry are far more than these, almostAll currencies will have the opportunity to rise or fall sharply, but this range of rise and fall is not like the 10% daily limit in stocks. Blockchain assets disappear from trading around the world 24 hours a day, and are implemented on T+0, and are There is no limit on the rise or fall. The price of any variety is completely affected by the limit on the rise and fall and the pursuit of funds. Most varieties have experienced an increase of more than 100% throughout the year, even several times higher. This kind of investment opportunity It is also difficult to find in other markets.

The currency circle is like Tai Chi. Only when a person is in a state of tranquility can he feel the opponent's strength and intention in the push hand for the first time. What I felt at the time was that only by clearing myself could I receive information to the greatest extent and fastest, and make correct judgments and responses. The same is true in the currency circle.

❹ What is blockchain

The English translation of blockchain is: block chain, block means block, and chain means chain. So let’s first talk about what a block is.
In the Bitcoin network, Bitcoin transactions are happening every moment, and these transaction information will be broadcast to every node through the Bitcoin network. But if there is no one to handle this transaction information, it will be very messy and impossible to check. Therefore, we need to find a bookkeeper to sort out the transaction information, package and save it, and package it well. The information is synchronized to each node through the network. This encapsulated information is called a block.
For example, I don’t have the habit of keeping accounts, so at the end of each month, I have no idea what I bought this month that caused me to be so poor. My wife showed up at this time, and she asked me to report every amount of money I spent to her. She wrote down my expenses in days, and then it was very clear. By the end of the month, she concluded that I was poor. It's because I earn too little.
What are the benefits of keeping accounts this way?
First, the context is clear and I can trace every expense I make. Correspondingly, in the blockchain, you can even trace the digital currency back to the moment it was mined by the miners. This also lays a theoretical foundation for the digital currency to be free of counterfeit currency.
Second, information disclosure. My wife knows exactly how much money I have and how much I have spent, thus avoiding the possibility of private money. Corresponding to the blockchain, this ensures the fairness of each node. How many coins you have does not change at your request. Everyone has an account.
In the Bitcoin network, it is stipulated that accounting should be done every 10 minutes, that is, a person is selected every 10 minutes (as for how to select this person, please stay tuned) to record the transactions that occurred within these 10 minutes according to a certain Record it as a block, stamp the block with a timestamp, and then add each block chain in strict chronological order.Pick it up. In this way, many blocks are connected in chronological order to form a chain structure, which is what everyone calls the blockchain.
If each block is regarded as a page of an account book, then the blockchain is an account book.
This account book is not a private account book written by the accountant and confirmed by the master.
It is a public account book kept by each participating node.
No one can tamper with the transaction information in the account books at will, and no one can tamper with personal rights and interests information.
This is the meaning of blockchain!

❺ Blockchain English

AMA——Ask Me Anything, usually refers to the question and answer activity held by the project party or the person in charge of the transaction

AMM——Automated Market Maker, automatic market maker model

AML——Anti-Money Laundering, anti-money laundering

BTC——Bitcoin, Bitcoin

The English word for blockchain is Blockchain.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain originated from Bitcoin. In recent years, the world's attitude towards Bitcoin has been ups and downs, but as one of the underlying technologies of Bitcoin, blockchain technology has received increasing attention.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography A new distributed infrastructure and computing method that ensures the security of data transmission and access and uses smart contracts composed of automated script codes to program and operate data.

❼ What is blockchain and what is its relationship with Bitcoin

Blockchain in English is Blockchain, which is a computer technology for distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. New application models. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system. Blockchain is the underlying technology of Bitcoin, which is like a database ledger that records all transaction records. This technology has gradually attracted the attention of the banking and financial industries because of its safety and convenience. It is a very important concept in the blockchain world. Many models, such as ledger maintenance, currency issuance, timestamp design, network maintenance, competition between nodes, etc., all rely on this central idea.

The first application of blockchain was Bitcoin, and many countries have recognized the legal status of Bitcoin. There is no Bitcoin organization or central bank in the world to issue Bitcoin. The credibility it relies on is algorithms, and it relies on testing algorithms and an account book and fair mechanism to ensure circulation.A mechanism is displayed that everyone recognizes and trusts. This is the principle of its self-use.

Nowadays, people’s concept of blockchain is still very general, and its applications are not very wide. However, in the next ten years or even decades, when it comes to blockchain, it will definitely be the most high-end technology that affects people of all ages. Everyone knows!

❽ Popular explanation of what blockchain is

Question 1: What is blockchain? Can you explain the principle of 10-point blockchain in plain language: decentralization A distributed accounting system
The core of blockchain technology is that all currently participating nodes jointly maintain transactions and databases. It makes transactions based on cryptographic principles rather than trust, so that any two parties who reach an agreement can directly Payment transactions are carried out without the involvement 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 accountBook. 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 problems such as high cost, low efficiency, value dispersion, "information islands" and insecure data storage. 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. bitsOne of the most basic characteristics of currency 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
The 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 system with de(multi)center trust as the core.A value circulation network that allows 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 equity, supply chain, points and other fields. Major domestic financial institutions and enterprises have taken a fancy to the new industry. value, they have developed their own blockchain platforms, and blockchain has instantly become a new innovative industry in China. 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 method of data storage, transmission and certification that is decentralized and contained in a distributed structure. It replaces the current Internet centralization with data blocks.The dependence on the central server enables all data changes or transaction items to be recorded on a cloud system, which theoretically achieves self-certification of data during data transmission. In a far-reaching sense, this goes beyond the traditional and conventional need to rely on a central server. The information verification paradigm 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 between human brain intelligence and machine intelligence. and sharing interface.

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 way for all people to participate in accounting. 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, including ours, and its prospects are incredible. 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. 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, soSo, 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. (The technical term for these computers is "mining machines", and the people who hold the mining machines are called "miners".)
Biying China is working hard on the digitization of assets and has 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. privateChain: 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 everyone and can be viewed by everyone 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!
