⑴ What does blockchain mining mean?

"Mining", as the name suggests, is the action that can appear in our minds, which is digging in the soil with a shovel, but Now we no longer use shovels, but computers. Instead of digging in the soil, we dig in a pool of data, and instead of digging for physical objects like gold and coal, we compete for the right to keep accounts. 1. Mining is the process of confirming transactions in the Bitcoin system over a period of time and recording the formation of new blocks on the blockchain. These miners are called miners. 2. Mining is a bookkeeping process, miners are bookkeepers, and the blockchain is the general ledger. 3. The accounting rights of the Bitcoin system are decentralized, that is, every miner has accounting rights. Miners who successfully seize the accounting rights will receive new Bitcoin rewards from the system. Mining is the process of producing Bitcoins.

1. What does mining mean?

Ancient mining can be traced back to the selection of stone materials in the Stone Age. Later, with the rise of the metallurgical industry, mining and mineral processing technology gradually developed. This article introduces the aspects of open-pit mining, underground mining, tunnel support, rock crushing, tunnel ventilation, lighting, drainage, lifting and mineral processing in ancient China.

Open-pit mining There are many surface outcrops, slopes or residual deposits of various metal veins or ore bodies. Therefore, open-pit mining became an important mining method in ancient times. Open-pit mining can be divided into excavation method and soil reclamation method.

2. Mining is the name for accumulated income from activities in Bitcoin.

Mining was brought about by the recent popularity of Bitcoin. Bitcoin is a virtual currency that can be exchanged for real currency. One of the ways to obtain Bitcoins on the Internet is to participate in related activities every day. These activities, like mining in online games, require slowly accumulating wealth in exchange for Bitcoins.

⑵ What does blockchain mining mean?

In 2009, Satoshi Nakamoto invented Bitcoin and set the number of Bitcoins to only 21 million. , join the Bitcoin network, participate in the production of blocks, and provide proof of work (PoW), you can obtain rewards from the Bitcoin network. This process is mining.

The concept of "mining" is taken from the existing concepts in our real economic life, such as gold mining, silver mining, etc. Because minerals are valuable, people are driven to pay labor force. dig.

Another important point of Bitcoin mining is that the miners participating in mining recognize the value of Bitcoin, and there are people in the market who are willing to spend money on the Bitcoins they mine. So, Bitcoin mining makes sense.

Bitcoin’s Currency Characteristics

1. Decentralization

Bitcoin is the first distributed virtual currency. The entire network is composed of users and there is no central bank. Decentralization is the guarantee of Bitcoin’s security and freedom.

2, popular all over the worldThrough

Bitcoin can be managed on any computer connected to the Internet. Anyone can mine, buy, sell or receive Bitcoin regardless of location.

3. Exclusive ownership

Manipulating Bitcoin requires a private key, which can be isolated and stored in any storage medium. No one can obtain it except the user himself.

4. Low transaction fees

Bitcoins can be remitted for free, but a transaction fee of about 1 bit cent will ultimately be charged for each transaction to ensure faster transaction execution.

5. No hidden costs

As a means of payment from A to B, Bitcoin does not have cumbersome limits and procedures. You can make the payment by knowing the other party's Bitcoin address.

6. Cross-platform mining

Users can explore the computing capabilities of different hardware on many platforms.

⑶ What does blockchain mean?

Blockchain is a term in the field of information technology.

Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". . Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

The Origin of Blockchain

Blockchain originated from Bitcoin. On November 1, 2008, a person claiming to be Satoshi Nakamoto ) published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on the architectural concept of an electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., which marked the The birth of coin.

Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

⑷ How does blockchain mining make money

The principle of making money by mining: PoW and mining.

In the beginning, Bitcoin could be mined using graphics cards, but in 2013, it was no longer possible to mine Bitcoin BTC using general-purpose computing programs for graphics cards. Bitcoins are now all mined using ASIC mining machines. ".

Similarly, the launch of Litecoin ASIC mining machines in 2014 also ended the history of Litecoin mining using graphics cards. The current digital currencies that graphics cards can "mine" are Ethereum ETH, Ethereum Classic ETC, and Zcash Zerocoin ZEC.

Graphics card "mining"t; is not a profitable business. In fact, the earlier you start, the higher the income will be, and the income will decrease as more miners and graphics cards are added.

To put it bluntly, buying a high-priced graphics card to enter "mining" will definitely kill you. Purchasing a professional mining machine is a more cost-effective choice. Nowadays, the essential tool for personal mining is a mining pool. The function of a mining pool is to gather a large number of mining machine computing power to increase your chances of mining coins. At the same time, the coins you can mine in the future are evenly distributed to your account in advance.

Take Bitcoin as an example. If the entire Bitcoin network now generates a block every 10 minutes, this block contains 25 Bitcoins. Assuming that there are 10,000 people in the world participating in mining, then within these 10 minutes, only one lucky person will take away the 25 Bitcoins.

Others have nothing to gain. The principle of the mining pool is that everyone forms a team to mine and allocate according to the agreed distribution method, so that the miners' mining returns tend to be stable and the miners' risks are reduced.

In order to enhance the cost performance, you can also purchase some practical mining machines like Wanke Cloud, which can be used as ordinary hardware products and can also be used for mining, killing two birds with one stone.

(4) The latest extended reading of Tencent blockchain mining

There are several core operations of blockchain transactions and digital currencies:

The transaction network connected by decentralized databases is called the blockchain. All our clients (including mining machines) keep accounts together, confirm transfer transactions, and issue a certain amount of digital currency according to time.

Because the winner takes all, small and medium-sized retail miners have to unite to form a "mining pool" and record the cumulative workload in Shares. The higher the joint computing power, the greater the probability that the mining pool consortium will find the digital currency first. Large, increase the probability of finding newly issued digital currencies, and divide the mined digital currencies. This is called the PoW workload proof mechanism.

⑸ What conditions are required for mining in blockchain technology

Miners need to configure a mining machine. There are two ways to configure a mining machine:
The first method It is a cutting-edge mining machine equipped to gain performance advantages in guessing games. The advantages of new mining machines are high computing power, low power consumption, high gross profit, and low shutdown price; the disadvantage of new mining machines is high fixed costs and the need to fill in the pits of this cycle first. Novice mining machines are suitable for new mining machines. The second way is to configure second-hand old-model mining machines at a low price. The advantage of old-model mining machines is that they are low-priced and can easily reach the return line; the disadvantages of old-model mining machines are that their performance is relatively poor and their life cycle is short. Veterans often play with older models of mining rigs.

⑹ Ranking of the top ten blockchain mining apps

The ranking of mobile mining apps is as follows:

1. ETH mobile mining. ETH mobile mining is a software that can make money through mobile mining. Users can trade with confidence in this software. All transaction information is open and transparent, and the latest currency policies can be seen every day.Policy.

2. HBC environmental protection chain. HBC Environmental Chain is a very easy-to-use investment and financial management app. Users can redeem environmental coins by completing mining tasks, and the mining gameplay provided here is very simple.

3. Fire brush horizon mining. Fire Brush Vision is a brand new blockchain money-making platform, where users can directly receive tasks and complete tasks to obtain rewards. There is no need to invest or energy, and they only need to use their spare time to purchase mining machines. That's it.

4. ABEL trading platform. A professional mobile phone mining software, users can easily obtain a variety of digital currencies here, and can also conduct various digital currency transactions here at any time.

5. Secoin Star Ecology. A very easy-to-use mobile mining software that provides users with a very convenient and easy-to-use mining machine. They only need to use some daily rest time to obtain a variety of digital currencies.

Mobile mining is very simple. Just download the APP and register an account. The ways to obtain rewards are similar. If you want to use this mobile mining APP and increase your computing power, you must use facial recognition, Alipay, and Taobao authorization. , Xuexin.com authorization, operator authorization, JD authorization, binding GXS wallet, backup wallet, inviting friends, and checking in online every day.

Possible disadvantages of mobile phone mining:

1. Stealing user privacy. Some apps pretend to be mining, but are actually collecting user information and C-side traffic, which may cause problems such as user information leakage.

2. Greatly shorten the life of mobile phones. For mobile phones with mining systems installed, apps quickly drain battery power, generate excessive heat, or put unnecessary pressure on device resources.

3. The most important thing is that mobile phone mining is actually mining for candy, and mainstream coins cannot be mined. It is difficult to mine mainstream currencies with mobile phones. Nowadays, mainstream currencies such as Bitcoin and Ethereum cannot be mined with the computing power of mobile phones.

⑺ Give an example of what is blockchain

Question 1: 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 operation of data blockchainIt has a similar function to 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 2: What is the transaction process of the blockchain? Best to give an example 20 points 1. Definition
Blockchain is like an open network ledger. It originated from Bitcoin and is the underlying technology of Bitcoin. In a Bitcoin transaction, all the information recorded in the transaction is packaged into a "Block" for storage. With the expansion of information exchange, blocks are linked to each other, forming a blockchain.
2. Characteristics
Digital currency represented by Bitcoin is a peer-to-peer electronic cash system. Among them, each transaction will be broadcast to all participants in the network, and will be recorded in the ledger after multiple confirmations. This ledger is the "blockchain". Each participant will have his own ledger. In this way, when false information occurs, it can be broken through mutual verification, thereby ensuring network security.
In the blockchain, every node is equal, and there is no centralized management organization. This "decentralization" feature makes the blockchain unnecessary to rely on third parties, and its operation does not require any human effort. intervention, capable of independent self-validation. In addition, the blockchain network is open to the world, and anyone can query data through the public port, so the entire system is highly transparent.
3. Application
In short, the blockchain is a trusted database and a reliable "ledger". In the future, it will be used in cross-border payments, securities, loans, voting, etc. For example, in cross-border payments, with the security provided by blockchain, money can be sent to the world anytime and anywhere, thus eliminating many intermediate links and high handling fees.

Question 3: What is blockchain? What does it mean in layman’s terms? China on blockchainWhat is the attitude? 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
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, and multiple solutions that support the expansion of business forms.Chain ledger technology, interconnection technology between heterogeneous blockchains, etc. 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 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 is attracting more and more attention and will form a huge new trend... >>

Question 4: 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 BitcoinIt has been controversial since its inception and cannot even be regarded as a "currency" by governments and monetary authorities. However, the blockchain technology used in Bitcoin has received widespread attention, including from governments and monetary authorities.
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, enriched 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 protocols (rules or constitution). 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 5: The so-called "district" What is "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 6: What is blockchain? Can you explain the principle of 10-point blockchain in plain language: decentralized distributed accounting system
Blockchain The core of the 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 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 fastest generates a new block and broadcasts it.Update all nodes to complete 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 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 those that require credit guarantees must be centralized, third-party intermediaries.activities to participate in. 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 7: Explain clearly what is blockchain in an easy-to-understand manner. The English name for 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. (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 8: What is blockchain? Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
In May 2016, the Currency Blockchain Research Center published the first book in China that introduces blockchain in simple terms, "Blockchain: Defining a New Pattern of Future Finance and Economics." It introduces the impact of blockchain technology on future finance and economy

Question 9: What is blockchain? For the time being, this is a relatively high-end technology. It connects all nodes (which can be understood as servers) through p2p network technology. Complete data (blocks) are stored on each node. The addition and withdrawal of any node will not affect the normal operation of the chain. The data isIt is embodied in the form of data blocks. Blocks are connected to each other and can be understood as a one-way linked list. The hash value of the nth block is generated based on the hash of the n-1th block, the transaction recorded in the current block, and the random number as parameters. In this way, if you want to modify the data of the historical block, you have to modify all the blocks from the modified block to the final block. The difficulty can be imagined.
The blockchain also introduces a consensus mechanism and an incentive mechanism. There is no way to describe it too comprehensively here. I hope everyone can discuss and learn together

Question 10: What is blockchain: This explanation of blockchain is more understandable. Blockchain (Blockchain) refers to the method of decentralization and trustlessness. A technical solution for collectively maintaining a reliable database.
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.
