A. 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 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 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". EveryParticipants will have their own ledgers. 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? 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
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 they are not being built.It is recommended that any non-professionals 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 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 a block?Chain 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 brand-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 fully applied in 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, and there has been no record of funds or user information being stolen. Its security has been verified, andAnd its efficiency and cost of fund clearing 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 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 it in plain language? 10 points The principle of blockchain: decentralized 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 conduct payment transactions without the need for a third party. Participation of three parties.
?
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, the 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 meet the information needs of market participants, so intermediaries and centers were 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 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 asset digitization and 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, encryption algorithm, etc. 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. Data 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.

B. What are the legal blockchains in China?

1. Mainly alliance chainsCompanies that provide blockchain technology services are basically in compliance with legal regulations. It mainly includes Tencent Blockchain, Network Super Chain, JD Blockchain, Ant Blockchain, Shanghai Wanxiang Blockchain Co., Ltd., Hangzhou Qulian Technology Co., Ltd., etc.

2. Companies focusing on blockchain information services, such as blockchain information, blockchain communities, digital currency market software, etc. Mainly including Babbitt, chain nodes, non-small accounts, etc.

3. Companies that produce mining machines and provide related computing services, such as Bitmain, Canaan, Yibang International, etc.
Extended information:
Price-to-book ratio: refers to the ratio of stock price per share to net assets per share. The price-to-book ratio can be used for investment analysis. Generally speaking, stocks with a lower price-to-book ratio have higher investment value. On the contrary, stocks with lower investment value.
Opening price: 9:15-9:25 am is the call auction time. During the call auction period, the exchange's automatic matching system only stores but does not match. When the application bidding time ends, the matching system will based on the call auction. In principle, the opening price of the stock on that day is generated. According to the regulations of the Shanghai Stock Exchange, if there is no transaction of a certain security within half an hour after the market opens, the closing price of the previous day will be the opening price of the day. Sometimes there is no transaction for a certain security for several consecutive days. The stock exchange will put forward a guide price based on the price trend of the customer's order for buying and selling the security, and then it will be used as the opening price after the transaction is completed. The average price or average offering price of securities traded over the counter on the day before listing on the first day of listing is the opening price.
Close: The closing price refers to the transaction price of the last transaction of a certain security before the end of one day's trading activities on the stock exchange. If there is no transaction on that day, the last transaction price will be used as the closing price, because the closing price is the standard for the current day's market and the basis for the opening price of the next trading day, which can be used to predict future securities market conditions; therefore, investors are optimistic about the market situation. When analyzing, the closing price is generally used as the basis for calculation.
Trading: It means that investors do not actively buy and sell, but adopt a wait-and-see attitude, causing the stock price to change very little on the day. This situation is called trading.
Consolidation: It means that after a period of sharp rise or fall, the stock price begins to fluctuate slightly and enters a stage of stable change. This phenomenon is called consolidation, and consolidation is the preparation stage for the next big change. Panjian The stock price rises slowly, which is called Panjian. A slow decline in the stock price is called a soft market. Retracement refers to the phenomenon that during the rising process of stock price, it temporarily falls back due to excessive rise. The number of transactions refers to the number of transactions of various stocks on the day. Trading volume refers to the total price of each stock traded on the day. The last bid price refers to the price that buyers want to buy after the market closes that day. The last bid is the seller's asking price after the market closes that day.

Industry Overview

1. Definition

In a narrow sense, blockchain is a combination of data blocks that are connected sequentially in chronological order. It is a chain data structure that is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.

Broadly speaking, blockchain technology uses a block chain data structure to verify A new distributed method that stores data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate data. Infrastructure and computing methods.

Blockchain is not a single technology, but a combination of new technologies. Each of the technologies performs its own role, solves different problems, and is combined together A blockchain is formed. As the basic structural unit of the blockchain, the block consists of two parts: the block header and the block body containing transaction data.

2. IndustryChain analysis: The downstream industry covers a wide range

The upstream of the blockchain industry chain is mainly the underlying technology and infrastructure. The underlying technology includes core basic components, protocols and algorithms. Represented by Bitcoin, Litecoin, and Ethereum, a network environment such as distributed algorithms, digital keys, data storage, P2P network protocols, and consensus mechanisms based on blockchain technology, transaction rules, and incentives for miners to join network nodes have been built. Mechanism, representative companies include Xiaoyi, Quantum Chain, Wanxiang Blockchain, etc.; the infrastructure is mainly mining machines.

The midstream is the platform layer, which mainly provides developers with applications based on blockchain technology. It provides productized services such as smart contracts, information security, and data services based on the underlying technology to improve development It provides convenience and scalability for developers to develop applications at the platform layer.

Downstream is the vertical industry application layer. It manifests itself as core application components, including smart contracts, programmable assets, incentive mechanisms, member management, etc.

Industry development history: We are in the era of blockchain 3.0

From the perspective of the development history of global blockchain, in 2008, an anonymous person signed by "Satoshi Nakamoto" published The paper "Bitcoin: Peer-to-Peer Network Electronic Cash System" originally expected to launch a peer-to-peer electronic cash that could circulate freely. The issuance of Bitcoin represented the beginning of blockchain technology; later, in 2013, the launch of Ethereum directly Pushing the blockchain into the 2.0 era; at the end of 2017, the popularity of stablecoins and the launch of MakerDAO pushed the blockchain into the 3.0 era. By June 2019, Facebook released the Libra white paper, which attracted attention and discussion from all walks of life around the world, and various countries regulated Departments have spoken out one after another, showing the huge potential of blockchain technology in reshaping global financial infrastructure. After entering 2021, NFT-based identification technology has emerged and is the first to be applied in the art field.

Industry policy background: Promote the all-round development of blockchain

In 2016, the State Council issued the "Thirteenth Five-Year Plan for National Informatization", which listed blockchain as a new technology for the first time The scope and cutting-edge layout indicate that my country has begun to promote the development of blockchain technology and applications. Since then, various localities in the country have successively introduced blockchain-related policies, providing a good environment for the development of blockchain.

In February 2019, the "Blockchain Information Service Management Regulations" issued by the State Internet Information Office were officially implemented, standardizing the filing basis for the development of my country's blockchain industry. The purpose of promulgating the "Regulations" is to clarify the information security management responsibilities of blockchain information service providers, standardize and promote the healthy development of blockchain technology and related services, avoid blockchain information service security risks, and facilitate the provision of blockchain information services. , use, management, etc. to provide effective legal basis. The introduction of this "management regulations" also means that my country's "supervision era" for blockchain information services has officially arrived.

At the end of October 2019, the Political Bureau of the CPC Central Committee held its 10th meeting on the current status and trends of blockchain technology development.After eight collective studies, central leaders clearly emphasized that blockchain should be an important breakthrough for independent innovation in core technologies and accelerate the development of blockchain technology and industrial innovation. This fully demonstrates that blockchain technology has risen to a national level. Chen Chun, a professor at Zhejiang University and an academician of the Chinese Academy of Engineering, who gave a lecture on the collective study of the Political Bureau of the CPC Central Committee, said at the 2019CCF Blockchain Technology Conference hosted by the Computer Society of China on October 12 that the development of the domestic blockchain industry is ushering in " "Spring Breeze", the research hotspots of China's blockchain technology will focus on two aspects: the key technology of the alliance blockchain and the blockchain supervision technology.

Industry development prospects and trend predictions

1. It is still in the introduction period

Currently, my country’s blockchain industry is in the introduction period, and the industry is showing Two main characteristics: First, large industry companies are actively applying blockchain technology to improve their own businesses, but they are still mainly trying, and the main application scenarios are also non-core businesses in the industry. For example, enterprises such as Ping An of China, China UnionPay, and Ant Financial are limited to non-core businesses in their exploration of blockchain applications; secondly, the business development of enterprises focusing on blockchain technology services is mostly in the initial stage, and their product technology systems and The business model is not mature enough, and the demand side’s understanding of blockchain needs to be improved. Blockchain has already formed some application cases in scenarios such as judicial certificate storage, government affairs management, people's livelihood services, food traceability, supply chain management, etc., but it still needs to be further optimized and improved.

The above data refers to the "China Blockchain Industry Market Foresight and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute.

E. Does BcHc have development prospects?

Yes.

BcHc is caused by the hard fork of Bitcoin Cash. In response to the development trend, Bitcoin Cash hard forked into two forked coins. BCHC is a platform general pass issued by the BitCherry distributed e-commerce network using the underlying blockchain technology and pass attributes, and its value is closely related to the BitCherry distributed ecology.

BCHC can be used to purchase platform products or be paid as rewards to ecosystem partners.Contributing participants. The value of BCHC will be determined jointly by all participants in the BitCherry ecosystem.

As the BitCherry ecosystem continues to expand globally and continues to establish and improve the economic sharing system, the demand for BCHC in the entire ecosystem will continue to increase, and its value will continue to increase.

Lack of supervision:

But some people are worried that Bitcoin will become A hotbed of drug dealing, money laundering and other nefarious activities. A website called Silk Road, which provided a platform for criminals to trade in Bitcoin, was shut down by U.S. authorities earlier this month. U.S. police said on October 25, 2013 that they found Bitcoin worth $2.8 million in the computer of Ross William Ulbricht, the website owner.

Reuters reported that this website has been operating since 2011 to build a trading platform for criminals. The website sells heroin and other drugs, and even provides killers. More than 900,000 registered users of the site use Bitcoin to trade drugs. Court documents show that the website completed $1.2 billion worth of Bitcoin transactions during its two years of operation and charged a fee of 8% to 15% for each transaction.

AFP reported that Bitcoin has not been effectively regulated in any country or region. Germany is the first country in the world to recognize Bitcoin as a “private currency.”

F. Bitcherry BCHC proposed "Blockchain 4.0" to promote the application practice of blockchain and e-commerce industry

With the continuous development of blockchain technology, it seems that many industries If you want to have something to do with the blockchain, there is a popular saying in the world: "Whoever gets the blockchain will win the world." So is this blockchain really as amazing as everyone says? How will blockchain finally be implemented? Today, let’s first talk to you about the application practice of blockchain in the field of “e-commerce”.

First, let’s briefly review what is e-commerce? E-commerce was born in the 1990s. It is a business activity that uses information network technology as a means and commodity exchange as the center and side. We call e-commerce "EC" for short. Many people think it is the ultimate major commercial use of the Internet, so they call it an epoch-making symbol.

According to data from US market research company Forrester, by the end of 2018, China’s e-commerce market is expected to reach US$1.1 trillion, becoming the world’s first trillion-dollar e-commerce market. The report points out that by 2022, China's e-commerce market will reach US$1.8 trillion, far exceeding the United States and Japan.

With the expansion of e-commerce, it has also greatly promoted the development of logistics, customer service and other industries. But at the same time, it also brings many problems. According to the e-commerce consumer dispute mediationData from National Taiwan University shows that the number of complaints received in the first half of 2018 increased by 66.93% year-on-year, a growth rate much higher than in previous years.

In order to solve the pain points of e-commerce in aspects such as counterfeit goods, logistics, integrity, and supervision, major companies and platforms are also showing off their skills and tricks. The most eye-catching one is our protagonist: blockchain. So how does it solve these problems?

First, supervise the production process of goods.

Second, trace and track the transportation of goods.

Third, guarantee product sales and after-sales service.

Fourth, protect user privacy.

The distributed e-commerce platform Bitcherry BCHC solves the platform trust crisis

Bitcherry BCHC is the world’s first distributed e-commerce platform. It is based on blockchain technology and is committed to To create a super ecology covering all aspects of clothing, food, housing and transportation. In the community ecology, all participants, such as users, merchants, super nodes, operating nodes, etc., use the token system for everyone's participation and economic sharing to open up the online and offline O2O e-commerce system, making the entire ecology healthy and autonomous. , develop healthily.

It is understood that the distributed e-commerce network has multiple payment methods, distributed sharing mechanisms, behavioral token incentives, distributed open platforms, multi-industry and multi-community access, and operating nodes around the world. , decentralized distributed business organizations, community self-propagation and ripples and other characteristics.

At present, consumer information is leaked, everyone has become a "digital labor", merchant profits are reduced, customer acquisition costs are increasing day by day, supply chain supervision is lacking, and product quality problems occur repeatedly, which is the problem for most centralized e-commerce companies. main pain points. Different from the centralized model of traditional e-commerce platforms, the underlying technology of distributed e-commerce platforms is a distributed accounting method that allows transaction data, dissemination, purchase, circulation and other behavioral data to be uploaded to the chain, making it open, transparent and non-tamperable. In distributed e-commerce based on blockchain technology, industry issues such as product traceability, logistics supervision, user evaluation and community incentives are all well-founded and well-founded. It returns data, traffic and value to the parties involved in the transaction, effectively solving the various shortcomings of centralized platforms.

To promote the implementation of blockchain in actual business scenarios, Bitcherry BCHC proposed "Blockchain 4.0"

According to the reporter's investigation, Bitcherry BCHC will adopt a two-stage implementation of "Blockchain 4.0" 4.0” target. Providing a public chain with high TPS and compatible with Ethereum smart contracts is the first phase of Bitcherry BCHC's measures to ensure the safe and efficient circulation of digital assets in the e-commerce ecosystem. second stage, Bitcherry BCHC will provide a large public chain environment that supports the e-commerce ecology - an e-commerce vertical blockchain network platform, allowing e-commerce operators to quickly realize digital operation transformation in the digital economy era and achieve mutual diversion in the e-commerce ecology. In addition, the reporter learned that the large public chain environment will also provide a governance structure, including a smart contract-based complaint mechanism, reputation scoring, arbitration mechanism, etc., to prevent fraud and damage to the interests of consumers and digital asset investors, and ensure the e-commerce ecosystem compliance and healthy development.

In terms of technology, the Bitcherry BCHC public chain will combine blockchain and DAG technology to provide a chain network system, and the main chain will provide guarantee for the security of the entire system. Use signature algorithms, distributed storage, data operations, consensus mechanisms, message diffusion and other technologies to optimize the distributed e-commerce network architecture, and use a decentralized and non-tamperable structure to allow all participating entities in the Bitcherry BCHC ecosystem to establish a trust mechanism to achieve Second-level fast transaction verification by all parties is the main technical feature of the Bitcherry BCHC project.

G. What currency is BCHC

bchc is a digital currency resulting from the hard fork of Bitcoin Cash.

There are two types of Bitcoin Cash hard forks: BCHC and BSV. The reason for the fork is also caused by differences in community consensus.

BCHC still follows the general direction of Bitcoin Cash, but diversifies its future application methods, similar to Ethereum ETH after the fork. BCHC's supporters and computing power support are greater than the latter BSV.
