『一』What are the applications of blockchain in social security fee collection and real estate transactions

On March 24, the "One" issued by the General Office of the CPC Central Committee and the General Office of the State Council "Opinions on Further Deepening the Reform of Tax Collection and Administration" was released, and the opinions proposed to deepen the sharing and application of tax big data. Explore the application of blockchain technology in social insurance premium collection, real estate transactions and real estate registration, and continue to expand its application in promoting tax-related and fee-related information sharing and other fields. Continuously improve the tax big data cloud platform, strengthen the development and utilization of data resources, and continue to promote interconnection with the information systems of the state and relevant departments.
In social insurance, the use of blockchain electronic signature technology can synchronize the entire document signing process (document hash, signing subject, signing time, signing location, signing equipment, etc.) to the notary office, arbitration committee, Authoritative judicial institutions such as the Internet Court effectively ensure that policyholders’ information cannot be tampered with, time cannot be tampered with, and electronic data cannot be tampered with. As the only blockchain electronic signing platform in China that is connected to the National Judicial Center, Junzizhuan can protect policyholders’ electronic signatures based on the above technology. The authenticity, completeness and legal validity of the contract.
Blockchain digital tools represented by electronic contracts will become an important driving force for the digital transformation of real estate companies. As a professional domestic blockchain electronic signing platform under Yibaoquan, Junzizhuan can integrate with major software systems such as real estate enterprise OA, procurement software, bidding software, and project management systems to integrate all real estate companies’ current situation and needs. The work of signing documents and contracts has been moved from offline to online, and the entire process of document drafting, review, sealing, storage and transmission is completed electronically, which can well solve the above operation and management pain points faced by real estate companies and open up the digitalization of real estate companies. The last mile of the transformation process.

『二』Blockchain has officially entered the 3.0 era, and real estate, supply chain, etc. will become key areas of application

With the continuous development of blockchain, the application of blockchain covers The scope is getting wider and wider. With the improvement of scalability and efficiency, the application scope of blockchain will go beyond finance and expand to fields such as logistics, real estate and the Internet of Things, becoming a bottom-level protocol in the future society. This also It means that the blockchain will enter the 3.0 era.

The blockchain 1.0 era is represented by BTC (decentralized concept), which plays more of a distributed accounting role, such as BTC, Ripple, BCH, Litecoin, Dogecoin, etc. It is more used for digital currency accounting. Of course, the development in the first stage is not perfect. Bitcoin still has many problems that need to be solved, such as expansion, lightning payments, hard forks, etc.

With further completion, the blockchain has entered the 2.0 era, represented by ETH (smart contract), entering the contract stage.

Blockchain 2 represented by ETH.0 is a big improvement, but there are still many problems, such as channel congestion, slow transaction speed, fork risk, high handling fees, etc. For example, after the popular CryptoKitties were launched on the Ethereum platform, they occupied about 25% of the Ethereum network at its peak, causing congestion on the entire Ethereum network and seriously affecting the experience of other Ethereum users. . The current development is a transition process from the first stage to the second stage.

After bidding farewell to the 1.0 and 2.0 eras, thanks to the continuous development of technology, blockchain has become more practical. This also means that the blockchain will completely break away from the financial attributes of the start-up period and enter practical application scenarios in all walks of life with its decentralization and other characteristics.

This also means that the blockchain has officially opened its 3.0 era - the era of comprehensive application. The blockchain industry structure in the 3.0 era is also more complex. Today I will give you a brief analysis.

The blockchain industry in the 3.0 era is divided into three levels: basic layer, service layer and application layer.

(1), Basic layer

The corresponding upstream, middle and downstream of the industrial chain include: upstream underlying technology and infrastructure (core technology, equipment, underlying platform deployment method), the midstream service layer mainly provides developers with applications based on blockchain technology; the downstream application layer includes finance, supply chain management, intelligent manufacturing, government enterprises, services, social applications, etc.

Hardware, technology and infrastructure manufacturers mainly provide chips, mining machines, mining pools, hard drives, routers and other infrastructure necessary for blockchain applications.

The underlying platform deployment methods can be divided into public chain, alliance chain, and private chain.

The underlying technology includes core basic components, protocols and algorithms. Based on the underlying core technology components, it provides different functions for different application scenarios, including smart contracts, programmable assets, incentive mechanisms, member management, etc.

The base layer provides the underlying blockchain or distributed ledger technology framework, mainly including Ethereum, Hyperledger Fabric, R3 Corda, FISCO BCOS, etc.

(2) Service layer

The service layer refers to the BaaS (Blockchain as a Service) platform. The main domestic BaaS platforms are Ant Blockchain BaaS platform, Tencent Cloud TBaaS, Ping An One Account BaaS platform, etc.

It 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 developers' ability to develop at the platform level. Application convenience and scalability.

Application and service vendors are responsible for the research and development of general blockchain technology and technology expansion platforms, digital currency education and storage platform construction, etc., and provide technology for the industry application layer. support.

(3) Application layer

The application layer is represented by core application components, including smart contracts, programmable assets, incentive mechanisms, member management, etc.

Refers to the end user or service provider of blockchain. The main application scenarios of blockchain now include cross-border payment, anti-counterfeiting traceability, and supply chain. Finance, trade finance, electronic bills, ABS, etc.

Service objects are divided into two categories: B-side (initial stage): blockchain + (finance, supply chain management, copyright protection, education); C-side (first to land): blockchain+ (sharing economy, pan-entertainment).

The downstream blockchain application field is the combination of blockchain technology and existing industries. Now, Many industries have begun the application era of blockchain 3.0.

(1) Blockchain + supply chain

Blockchain + supply chain enables full-process traceability of product information. The traceability and anti-counterfeiting system of the traditional supply chain has shortcomings such as opaque information, easy data tampering, poor security and relative closure. However, using blockchain technology and Internet of Things technology, the information on the raw material purchasing process, production process and circulation process of goods can be processed. Integration and traceability can truly realize the full-process authentic traceability across brands, channels, retailers, and consumers, down to each item and code, significantly improving user trust experience.

(2), Blockchain + Internet of Things

Build an information exchange network in the era of Internet of Everything. As the number of devices in the Internet of Things grows, the distributed nature of the blockchain provides a way for self-governance of the Internet of Things, which can help devices in the Internet of Things understand each other and understand the correlation between different devices, thereby realizing the distribution of the Internet of Things. type control.

(3), Blockchain + Medical

Ensure the safe sharing of medical data. Using blockchain technology to mathematically encrypt medical data can effectively prevent risks such as malicious modification of medical data. Apply blockchain technology to developThe medical data sharing and exchange system developed by the company uploads encrypted medical data, allowing data to be shared and circulated quickly, efficiently and safely between patients and medical institutions, effectively simplifying the medical data calling process and providing accurate Provide data protection for diagnosing conditions.

(4) Blockchain + Real Estate

There are many potential application scenarios of blockchain in the real estate industry. Common ones include: Real estate transactions. Pain points in the process of buying and selling property include: lack of transparency during and after the transaction, reams of paperwork, potential for fraud, errors in public records, and that’s just to name a few. Blockchain provides a way to achieve the need for paperless and fast transactions. In addition, real estate blockchain applications can help record, trace and transfer title deeds, deeds, liens, etc., and also provide a platform for financial companies, title companies and mortgage companies. Blockchain technology strives to securely preserve files while enhancing transparency and reducing costs. In addition, blockchain is also applied in the field of construction engineering, and many companies are applying this technology in the current urban renewal boom. For example, Shenzhen's Lanfang Chain has proposed a package of solutions including blockchain + urban renewal/construction engineering/real estate development based on blockchain, which comprehensively serves many fields in the real estate industry. Currently, its official website and mobile applications are online.

In addition, blockchain has already had many applications in supply chain finance, stock trading, banking, etc., so I won’t go into details here.

As one of the important contents of my country’s 14th Five-Year Plan, officials have already proposed to accelerate the promotion of blockchain Technological and industrial innovation and development, and actively promote the integrated development of blockchain and economy and society.

The key to achieving the above two developments lies in the following two points:

1. Breakthrough in the core technology of blockchain technology.

Blockchain technology is currently the technology with the smallest gap between my country and Europe and the United States. Officials particularly emphasize that in this emerging field, my country must be at the forefront of theory, occupy the commanding heights of innovation, and gain new industrial advantages. It is necessary to promote collaborative research, accelerate breakthroughs in core technologies, and provide safe and controllable technical support for the development of blockchain applications.

At present, most of the blockchain technology is still in the conceptual hype stage, and many business scenarios use blockchain purely for the sake of blockchain. So far, no one in our country has been able to solve core technical dilemmas such as the ternary paradox on a global scale. Therefore, we must return to basic theories and core technologies and achieve major breakthroughs through long-term and concentrated research.

In fact, the government has put forward very high requirements for the theoretical technology and subsequent application development of blockchain technology. We must do a good job in basic theoretical research on blockchain, focus on conquering a number of key core technologies, and truly grasp the Taking up the burden of technology research and development is the key to the current development of blockchain.

2. Enhance international voice and rule-making power.

Different from previous information technologies, blockchain technology is highly scalable, or aggressive. Its rules or right to speak determine its scope of influence, because every business on the chain is Individuals or institutions must obey the rules set by the blockchain, whether at home or abroad. For example, everyone must obey the rules of Windows when using the Windows system, but Windows only stipulates the rules for information interaction for users, which is acceptable to us, while the blockchain stipulates industry governance rules. With its distributed characteristics, the governance rules of the blockchain can quickly transcend national borders and geographical restrictions.

In order to achieve the above two points, we must strengthen the construction of the talent team, establish and improve the talent training system, create various forms of high-level talent training platforms, and cultivate a A group of leading figures and a high-level innovation team.

Blockchain, as an architectural innovation technology, has a huge demand for comprehensive talents, requiring practitioners to master a variety of professional and technical knowledge involving cryptography, information science, basic mathematics, etc. To develop blockchain, we must strengthen the construction of a talent team with deep cross-integration of disciplines, and establish a talent cultivation system in a forward-looking and systematic manner from the aspects of basic research, applied research and development, and industrial integration.

Blockchain technology is an important part of the future digital economy and has rich advantages for all walks of life. Although we have entered the 3.0 era, the vertical application of blockchain in various industries has just begun.

What do you think of the future of blockchain?

『三』How is blockchain developing now

In 2020, blockchain was included in the category of "new infrastructure" by the country, and at least 7 provinces introduced blockchain Support policies. In the same year, blockchain technology was gradually moving from concept to implementation, with many application scenarios blooming. "Blockchain+" various industry applications have become a symbol of the continuous maturity of blockchain.

The development status of "Blockchain+" in 2020

In 2020, the COVID-19 epidemic swept the world, and the uncertainty of world economic development increased significantly. Governments and enterprises of various countries are exploring the use of emerging technologies to reduce economic and social operating costs, improve the operating efficiency of the real economy, and further find new growth points for economic development.

Currently, blockchain, cloud computing, artificial intelligenceWith the cross-innovation of new technology infrastructure such as intelligence, more and more vertical fields of the real economy are showing a "blockchain+" development pattern and a good momentum of "moving away from virtuality to reality".

In order to avoid turning reality into fiction, in addition to continuing to severely crack down on speculation, we must also guide the deep integration of blockchain technology with practical application scenarios. Therefore, "blockchain+" various industrial application scenarios have become one of the inevitable trends in the development of blockchain.

According to the "Blockchain White Paper (2020)" recently released by the China Academy of Information and Communications Technology, as of October 2020, more than 262 listed companies have been involved in the blockchain field, each from insurance , real estate, commercial department stores, security equipment, packaging materials, telecommunications operations and other 39 fields. In the blockchain information service registration list released by the State Internet Information Office, there are 45 blockchain projects of listed companies.

Among them, finance is the most explored scenario among blockchain technology application scenarios, with specific projects implemented in subdivisions such as supply chain finance, trade finance, payment and settlement, and fund management. The white paper shows that as of November 2020, among the domestically registered blockchain information services, the number of projects in the financial (including supply chain finance) field ranks first, accounting for as high as 36%.

As the implementation of blockchain applications accelerates, "blockchain+" business has become the focus of development for Internet backbone enterprises to enter the blockchain industry. In addition to financial business, they actively deploy the Internet, traceability, Applications in supply chain & logistics, digital assets, government affairs and public services, intellectual property, law, medical and other fields.

At the same time, the industry is gradually understanding that blockchain is the basic component of trusted transactions, but this does not mean that blockchain can conquer the world. Blockchain needs to be combined with other technologies such as artificial intelligence, Internet of Things, big data, 5G, etc. to use synergy to form integrated solutions to jointly promote digital transformation.

According to relevant data, the current application of blockchain is mainly in the field of certificate storage. Blockchain has entered into how to make it better from an engineering perspective, more credible, more stable, and more scalable. Well, a stage that can accommodate more nodes. He Baohong, director of the Institute of Cloud Computing and Big Data of the China Academy of Information and Communications Technology, believes that this process will continue for some time or longer. In the next step, blockchain technology competition will shift from engineering optimization and improvement to technology ecology and business ecology.

In addition, it is understood that the blockchain industry is improving in the long term, and industry cognition has returned to rationality. With the central government's planning and guidance for the development of blockchain technology, my country's blockchain has clarified the development ideas based on the alliance chain, focusing on serving the real economy and optimizing public services, and the direction of industrial development has become clearer. At this stage, the confidence of the majority of practitioners in blockchain continues to improve, and the long-term strategic value of blockchain is generally recognized.

What is the prospect of "Blockchain+" in 2021?

As my country’s blockchain industry chain gradually improves, most blockchain companies not only focus on one aspect, but also present multi-field collaborations.same development trend. According to statistics, among the 801 blockchain information service registration lists released by the Cyberspace Administration of China, Beijing, Guangzhou, Shanghai, Zhejiang, Jiangsu, and Shandong are the provinces and cities with the most registered companies.

The core role of blockchain corresponding to its technical characteristics is mainly reflected in the three aspects of certificate storage, automated collaboration and value transfer. As its value potential is constantly being explored, application scenarios have evolved from the breakthrough point of finance. , and gradually expanded into many fields such as the real economy, government affairs and people's livelihood.

The core value of blockchain for the real economy is to promote efficient collaboration between upstream and downstream industries and improve the efficiency of industry-finance integration. In the early stages of development, the blockchain application model mainly focused on the storage of documents, contracts, etc. At this stage, blockchain industry applications are gradually moving towards automated collaboration and value interconnection such as government data sharing, supply chain collaboration, and cross-border trade.

2020 is the warm-up for 2021. In 2021, the use of blockchain, distributed ledgers, and smart contract tools will continue to grow as it did in 2020. With the continuous deepening of blockchain technology, the foundation of the blockchain industry will become better and better, the industrial ecology will also develop rapidly, and the industrial chain will become increasingly widespread.

From the perspective of industrial structure, the blockchain industry is mainly divided into four parts: underlying technology, platform services, industrial applications, and peripheral services.

The first three parts show a relatively obvious upstream and downstream relationship. The underlying technology part provides the necessary technical products and components of the blockchain respectively. The platform service part builds an area that can run corresponding industry applications based on the underlying technology. The industrial application part of the blockchain platform mainly uses blockchain technology to develop industry applications based on the actual scenarios of various industries and realize the innovation of business collaboration models within the industry.

The peripheral services part provides supporting services to the industry, including industry organizations, market research, standard formulation, system evaluation and certification, industry media, etc., to provide impetus for the development of industrial ecology.

Among them, as far as the industrial application of blockchain is concerned: Blockchain is the innovative development result of information technology, and it is also the main booster for the reconstruction of business processes and the innovation of industrial interaction models in various industries.

Blockchain has gradually expanded from the initial digital finance to supply chain finance, product traceability and other fields. Now it has been explored and applied in government affairs, people's livelihood, industrial management and other industries, and its application scenarios are becoming increasingly rich, presenting It has shown a development trend of deep integration with other industries.

At present, domestic enterprises are focusing on the development of applications related to serving the real economy and improving government affairs and people's livelihood. Among them, supply chain finance and product traceability have accounted for half of all applications. Others, such as government affairs and people's livelihood, have become the future of manufacturers. Key layout areas are about to experience explosive growth.

After blockchain investment cooled down in 2020, the blockchain industry may begin to gradually become more rational in 2021. However, a relatively complete industrial chain and active market entities provide a good foundation for the integrated development of the blockchain industry. The blockchain industry will also develop in terms of policy support, ecological construction, platform services, application implementation, and integrated innovation.Showing a positive development trend.

『四』 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 kind of ledgerIt’s “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? 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, and they are mainly overseas. Good domestic blockchain projectsThere are very, very few projects, so it is not recommended for any non-professionals to invest in blockchain projects. If you are very interested in blockchain technology and have a technical or financial background, it is recommended that you consider starting a business in this area. In terms of the blockchain protocol system, the lowest layer is the underlying technology of the blockchain, including the technical protocols of the blockchain, as well as some platform routing and basic algorithms; in the middle layer, some application interfaces and some credentials must be solved Issuance and verification, including some industry platform services, big data analysis, etc. This is a very rough classification, and there should be more detailed classifications; the top ones are some applications of blockchain, including finance Some applications and some applications in other aspects, the Internet of Things and so on.
Introduction to Bubi Blockchain
Bubi Blockchain has been focusing on the research and development and innovation of blockchain technology and products since its establishment. It has a number of core technologies and has achieved substantial results in many aspects. Radical innovation has resulted in a number of core technological achievements, such as: mathematically provable distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, and interconnection technology between heterogeneous blockchains. wait. On April 25, "Gege Points" introduced the concept of blockchain into the points system, jointly opened it up with multiple parties, issued and redeemed points, and promoted the circulation of points. Each cooperative institution can jointly participate in transaction verification, ledger storage, and real-time settlement; the third-party payment platform of the enterprise points issuer makes the entry and exit of points more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open value circulation network with decentralized trust as the core, allowing digital assets to flow freely.
A simple understanding of blockchain is a technology at the bottom of Bitcoin, which is also a peer-to-peer electronic cash system that can realize peer-to-peer value delivery. We should distinguish between Bitcoin, Bitcoin blockchain, blockchain and blockchain. Blockchain technology and other concepts. In countries with relatively developed finance in the past, finance and blockchain technology have a long history, and the legislation of digital currencies and blockchain networks is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own teams and conceptual technologies. Slowly, banks in various regions are also participating in digital currency discussions. The application and support of this technology are not only that. The influence of blockchain on enterprises is also huge. For larger domestic enterprises, Bubi Blockchain is also used in various 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 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 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, and 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. Principle of blockchain: GoCentralized 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 Conduct payment transactions directly 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 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 are there blocks?Chain Innovation
Human beings need to communicate in the process of activities, and communication is based on information. In the past, information circulation was not convenient enough to meet the needs of market participants for information, 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, 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. 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.

『Wu』Blockchain for 12 years: In what fields has it been applied?

#"The Shining Moment" Theme Essay Collection Issue 2#

People have talked about the applicable scenarios and usage opportunities of blockchain countless times. But in fact, it is very stupid and ridiculous to simply and crudely bundle blockchain with all businesses.

If you just use the word "blockchain" (rather than the technology behind it) to hype it, the result will be in vain. But if used properly, blockchain can indeed promote the development of certain economic sectors.

To achieve this goal, you need to take it slowly, step by step. Gartner experts believe that blockchain is currently on the verge of “escape from fantasy” stage. At this stage, its technical shortcomings were fully exposed, and most media from all walks of life were critical.

So, are there any good products that are truly based on blockchain? If so, in what areas?

First of all, financial services are a good choice. After all, many traditional intermediaries suffer from low transparency and high commissions. Currently, many large banks are already researching and testing decentralized solutions. So what are the options available on the market now?

Netting is a good example. It is based on Hyperledger Fabric and is capable of offsetting multiple positions or payments resulting from transactions between two or more parties. Often used to determine which party should receive remuneration in a multi-party agreement. Netting, as a general concept, has many more specific uses in financial markets (in securities trading).

In addition, there is endless discussion about blockchain bonds, mortgages and bank guarantees. Almost all big banks, including Islamic banks, are trying this approach.

Hyperledger Fabric and Corda blockchain technologies are also often used in other use cases, but the prospects require us to draw final conclusions through continued follow-up and observation.

Bank of America, Goldman Sachs, Citibank, Morgan Stanley, JPMorgan Chase, Bank of China and Commonwealth Bank of Australia have all achieved good results in 2019. In addition, in the banking industry, people often talk about cross-border financial transactions, and there is even an intention to get rid of SWIFT.

Some people believe that blockchain technology has great prospects in copyright protection and combating data fraud. For example, for the purpose of copyright protection, the startup Sputnik DLT developed the Depositor service on the Waves platform.

Likewise, Emernotar is a similar solution based on Emercoin, using the SHA-512 algorithm.According to the developers, businesses and lawyers can use the Emernotar service to sign contracts, use the online service to collect user consents, and creative industry representatives to confirm copyright.

The democracynotary.org platform, powered by Emercoin technology, aims to protect important election-related information. Although the blockchain cannot yet guarantee the anonymity of voting during the election process, it can at least guarantee the authenticity of voting.

The effectiveness of this platform was recently put to the test in a Macedonian referendum on ratifying a treaty with Greece that called for changing the country’s name to “North Macedonia.” ". The platform notarized public reports from the referendum process, thereby blocking the spread of false information.

Blockchain use cases are extremely promising in the registration of real estate transactions. Last year, there were attempts to leverage smart contracts on the Ethereum blockchain to conduct such buy/sell transactions in jurisdictions. While not all local legislatures understand what lawyers are doing, there have been and will be attempts.

For example, the most famous example was a deal to sell 10 acres of land through a decentralized Propy marketplace in California, conducted entirely in Bitcoin and using blockchain To register. Since then, the EU has also completed its first blockchain real estate sale.

In December 2018, the Swiss Financial Market Supervisory Authority approved the business model of the blockchain company “Blockimmo Real Estate Company”. Currently, the Blockimmo platform is in a testing phase and is available to residents of Switzerland and Liechtenstein. After that, the company plans to enter other markets throughout Europe.

Some experts are very optimistic about the application prospects of blockchain in the wholesale and logistics fields; but at the same time, some experts believe that it has no use in this field. However, as consumers, we should recognize the success that has been achieved in the industry.

In the late autumn of 2018, oil giants BP and Shell, as well as large banks and companies, launched the Vakt blockchain platform, which aims to optimize the commodity transaction process - including converting paper documents into smart contracts .

At the same time, the UAE is also using blockchain technology in the field-Maqta Gateway LLC launched the first blockchain logistics solution in Abu Dhabi. The Silsal blockchain technology developed by the company can improve logistics and freight efficiency. Maqta Gateway hopes to use DLT technology to reduce paperwork, facilitate real-time status updates and speed up information sharing.

Last fall also launched the IBM Food Trust BlockchainChain Platform - The platform is based on Hyperledger Fabric technology and is designed to regulate the food industry supply chain. Well-known companies such as Carrefour, Nestle, Dole Food, Tyson Foods, Kroger, Unilever, and Walmart are among the Platform members. Monthly fees for IBM blockchain services range from $100 to $10,000, which explains why these industry giants are willing to invest in this area.

The decentralized Shelf.Network auction protocol was launched in the fall of 2017. Car dealers can conduct car sales and leasing transactions through the platform.

A year later, the auction network received investment from Japanese IT giant Broadleaf. At the same time, Broadleaf has also obtained a license to supply Shelf.Network technology to establish a trading network for automobile and parts sales in Southeast Asian countries (including Japan, Myanmar, Thailand, Indonesia, Vietnam, Laos, Australia, India and Singapore).

By the end of 2018, 60,000 vehicles from the United States had joined the service network. Shelf.Network also implements interaction with the Carfax web service, through which vehicle history reports can be provided to individuals and businesses. For example, startup Auto1 Group GmbH recorded the purchase of a car in Germany through blockchain for loan and insurance products, significantly speeding up the transaction (which would have taken two weeks to complete with traditional paperwork).

A survey of large companies conducted by the IBM Institute for Business Value shows that by 2021, blockchain will play a key role in the automotive industry, and at the same time, blockchain will also be used in the aviation field . For example, S7 Airlines and Alfa Bank (Russia) have enabled real-time payments for aircraft fuel costs by applying smart contracts on the Hyperledger blockchain platform.

All walks of life in the industry believe that DLT technology can simplify and speed up mutual settlement processes, eliminate various financial risks, and automate processes. As in the field of wholesale logistics, this technology also has important application significance in the field of transportation.

Blockchain technology is also gradually penetrating into the public sector and is widely used in document authentication processes. For example, the Proofstack service is able to archive files with the owner’s personal signature, date and time stamp, and then writes the archive hash to the blockchain. Users can also select the country that affects the type of timestamp, as well as the storage location (computer, cloud) required to generate the archive. peopleWe can use the created archive to confirm when and by whom the file was archived. At the same time, the application of blockchain in the judicial system is becoming more and more popular. For example, ServeManager and Integra have applied blockchain technology to services that track subpoena delivery.

In China, government-backed blockchain solutions continue to develop rapidly. Its judicial blockchain system "Tianping Chain" has collected about 1 million pieces of online evidence data just three months after its release. All materials submitted on the platform are DLT certified, totaling 190,000 documents. The platform electronic evidence system was jointly developed by the Beijing Internet Court, the China Industrial Control System Emergency Response Team (CICS-CERT), the Research Center of the Ministry of Industry and Information Technology, the Network Internet Group and the TrustDo blockchain startup. The platform is based on the hyperchain infrastructure of the Internet giant network, optimizes the evidence collection and storage process, and ensures the authenticity of the data through the blockchain. In addition, the platform also achieves the purpose of saving time and resources by reducing Internet-related litigation costs.

As a global leader in container shipping, Maersk began using Insurwave blockchain solutions last spring. The marine insurance platform was jointly developed by consulting firms EY and Guardtime and is based on Microsoft Azure cloud technology. In the first year of cooperation with Insurwave, Maersk plans to insure 1,000 ocean-going vessels, and the total number of digital transactions will exceed 500,000.

Currently, platform users include Willis Towers Watson, XL Catlin and MS Amlin. Developers are trying to expand Insurwave's capabilities to expand insurance into the aviation and energy sectors.

Calastone, a British financial technology company specializing in investment flow management, announced that it will transfer all calculations to the blockchain. The company expects the technology to help cut billions of dollars in costs across its global settlement division. Calastone provides risk assessment management services, IT infrastructure and payment solutions to more than 1,700 companies, with clients including JP Morgan Asset Management, Schroders and Invesco.

If the enterprise's goal is to achieve transparency of transactions and information entered into the DLT registry, this will create an excellent application scenario for blockchain; however, if the enterprise is pursuing anonymity or "tracking "In financial transactions, there is no opportunity for blockchain to exert its influence.

Singapore Power Group launches Renewable Energy (REC) CertificatesBook blockchain trading market. Its company representatives said the "in-house developed" platform was designed to improve the security, reliability and traceability of such certificate transactions.

REC certificates are certificates that certify the amount of energy released by solar panels and are sold by Cleantech Solar Asia and LYS Energy Solutions. City Developments Limited and DBS Bank, who are interested in purchasing certificates, are both very interested in the platform. Katoen Natie Singapore has also joined the platform and plans to launch renewable electricity production capacity soon.

KT Corporation, South Korea’s largest telecommunications company, has also launched its own blockchain network, with distributed registration technology involving user authentication and improving international roaming services. This enables KT to securely transfer customer data to its partners. Network bandwidth can handle 100,000 transactions per second.

Time will tell whether these initiatives gain mass market acceptance. Likewise, the applications of blockchain in power, data, and user-identified accounts/records/transactions are old news.

At the end of 2017, the Massachusetts Institute of Technology (MIT) used the Blockcerts wallet, which can issue a "verifiable, tamper-proof" authentication certificate, to more than a hundred people through the Bitcoin blockchain. Graduates were issued digital diplomas.

The pilot project is supported by software company Learning Machine, which was involved in the development of Blockcerts together with Media Lab.

The purpose of this is to allow students to become the true owners of their own files. Learning Machine CEO Chris Jagers said that even if the agency ceases to exist, people will be able to extract important official information stored in it.

The same approach is used by Tbilisi University of Business and Technology: the university uses a similar blockchain platform, Trusted Diploma, through a partnership with Emercoin. The platform is able to restore registration data (subjects studied, quality of training and scores obtained) with the help of blockchain. From this point of view, in the future, blockchain may be useful in further promoting digital learning methods.

『Lu』 Blockchain technology will change these 18 major industries in the future

Blockchain technology will change these 18 major industries in the future
Since the birth of the Internet, information dissemination has Costs are greatly reduced and information disseminationEfficiency has increased rapidly, and social productivity has been liberated as never before. It is no exaggeration to say that the Internet has changed the entire pattern of human society.
However, while enjoying the many conveniences brought by the Internet, we have to admit that the Internet still has many flaws, especially in terms of security and mutual trust. The birth of blockchain technology has brought a new dawn to solve the problems existing in the Internet society.
Because blockchain technology is open and transparent, difficult to tamper with, and does not rely on intermediaries, blockchain can achieve safe, efficient, and low-cost value transmission. People are expected to build an Internet for value transmission based on blockchain to further promote the liberation of social productivity.
At the same time, just as "every new technology appears will change or even subvert many industries," in the future blockchain will change these 18 major industries!

1. Banking Industry
The application of blockchain technology in the financial field will change the transaction process and record keeping methods, significantly reduce transaction costs, and significantly improve efficiency.
2. Cybersecurity
Although blockchain is not a panacea to fix all Internet problems, it can be a powerful tool for experts and engineers, especially systems with single points of failure and centralized vulnerabilities.
3. Supply chain management
The supply chain is a complex functional network chain structure composed of suppliers, manufacturers, distributors, retailers, and users. In this chain, capital flow, information flow, and physical flow operate interactively, making coordination extremely difficult. The traditional coordination mechanism that relies on a single "chain owner" has encountered bottlenecks. The "decentralized" model of blockchain provides rich imagination for solving this problem.
4. Prediction field
The prediction market requires a platform that is decentralized, open and transparent, and more adaptable to global user participation to change the status quo, and this is a natural match with the characteristics of the blockchain. Whether from sports betting to stocks to elections, these technologies allow for decentralized betting and observation.
5. Network and Internet of Things
The idea of ​​applying blockchain technology to the Internet of Things (IoT) has been around for some time. In fact, blockchain technology looks to be a suitable solution for at least three aspects of IoT: big data management, security and transparency, and micro-transactions based on the exchange of services between interconnected smart devices. Comes in convenience.
6. Insurance industry
The power of technology is making the insurance industry return to its essence: linking objects, regaining trust, and sharing. In other words, the law of large numbers in the traditional insurance industry may encounter more uncertainties and create new possibilities due to technology, technology, and links.
7. Sharing Economy
Blockchain is inherently decentralized, which is highly consistent with the purpose of the sharing economy. The "Tencent Blockchain Solution White Paper" shows that Tencent is applying smart contracts to areas such as bicycle rental and house sharing. If this smart contract is usedToday's hot shared bicycle field may bring new changes to the entire industry.
8. Cloud Storage
Blockchain technology can support distributed storage of encrypted data and is the core of collaborative cloud storage.
9. Charity industry
For charity, the openness and transparency brought by blockchain technology can ensure that donors can clearly understand the flow of their funds and can query it; the non-tampering feature can also ensure that financial Information cannot be tampered with; anonymity also protects donor privacy.
10. Voting
Blockchain technology can be applied to voter registration, identity confirmation, and electronic statistics to ensure that only legitimate votes are recorded and that votes will not be tampered with or removed. Create an immutable, publicly visible ledger of voting records to make elections fairer and more democratic.
11. Government Management
Government services are one of the most direct and significant application areas of blockchain technology. Information exchange across agencies will effectively improve government efficiency.
12. Public welfare industry
Internet culture itself has the genes of equality, openness, and mutual assistance, which is very consistent with the characteristics of public welfare.
13. Medical industry
The medical industry currently still relies on old systems and lacks ways to store data securely. Blockchain can be widely used in medical and health information sharing, medical process transparency, and medical accident liability traceability.
14. Energy Management
In order for the Energy Internet to be successfully implemented, various information interactions, smart grid control and scheduling, and coordinated control of distributed power sources are all obstacles that must be overcome, and blockchain Technology is trying to solve these problems.
15. Music Copyright
The importance of music copyright is self-evident to online music platforms. Having more copyrights means that it can capture more users, and the platform can therefore obtain better Development opportunities.
16. Retail industry
When we shop, we need to trust the store’s retail system. Decentralized blockchain can make retail different, as buyers and sellers can connect directly without middlemen and fees.
17. Real Estate Industry
Blockchain technology can change the way the real estate market operates. It can merge many complex processes and cases that real estate companies usually deal with, speed up transaction processes, reduce fraud, and provide benefits for everyone. Participants provide more transparent and secure transactions.
18. Your industry
If your industry deals with data or any trading system, it is very likely to be changed by blockchain. This is an open field full of opportunities.
Of course, as an emerging technology, the application of blockchain still faces many challenges. More blockchain technology companies like Matrix are needed to overcome the difficulties in practical application of blockchain and promote blockchain technology. The widespread application and development of chains.

『撒』 How does Jinwowo Network Technology’s blockchain technology apply to the real estate industry?Application

『8』Why does second-hand housing transactions require blockchain?

With the rapid development of Internet technology, second-hand housing direct sales platforms have developed rapidly in recent years. Similar to "Lianjia Second-hand House Direct Sales Network" and "I Love My Home Without Intermediary Business", other representative second-hand house self-sale platforms aim to allow house buyers and house sellers to trade more directly, especially in the case of disputes arising from real estate intermediaries and transactions. have been solved to a certain extent. And will the emergence of these direct sales platforms de-intermediate second-hand housing transactions in the future?

Regarding this issue, we need to note that in the context of possible de-intermediation of second-hand housing transactions in the future, in addition to direct sales platforms, more reasons come from the development of blockchain technology. As blockchain technology becomes more mature, a new real estate platform called "Blockchain Real Estate Transaction Registration Platform" has begun to emerge, and its biggest feature is that it completely records housing transaction information on the blockchain. Let buyers and sellers have more security for each other.

From this perspective, the scenario in which second-hand housing transactions may be completely de-intermediated in the future is rather confusing. Because "complete deintermediation" does not mean "cancel the existence of brokers" or "cancel intermediary services", but means that house buyers and house sellers complete the house buying and selling process more directly through transactions on the blockchain platform. , and have more effective protection in terms of information.

But in any case, from the perspective of consumers, the impact of such deintermediation on consumers in the future will be extremely profound. On the one hand, based on blockchain registration, consumers can obtain a more convenient, secure and transparent housing transaction experience. For example, in house purchase and sale transactions, such a system will realize mutual supervision and use blockchain to eliminate unnecessary intervention by intermediaries. On the other hand, it will make consumers' housing transactions safer, and records of fraud that cannot be related to disintermediation will be completely recorded on the Bingzhi blockchain to protect consumers' legitimate rights and interests from infringement.

Taken together, the emergence of second-hand house direct sales platforms and the gradual maturity of blockchain technology will have a profound impact on second-hand house transactions in the future. Second-hand housing transactions may be de-intermediated in the future. In this context, consumers can obtain a more transparent, convenient and secure housing transaction experience, which will expand the development space of China's real estate market and help China's real estate industry become healthier and more stable. Development

『玖』 What kind of industry growth will the development of blockchain bring?

Policies and markets drive the development of the blockchain industry The prospect is bright

In the context of the rapid development of blockchain, China is adapting to the needs of globalization, keeping up with international pace, and activelyExtremely promote the research, standardization and industrialization development of domestic blockchain-related fields. Compared with the background of increasingly strict supervision of digital currencies such as Bitcoin, support and encouragement for blockchain technology has reached a global consensus, and domestic blockchain technology will also receive national and local policies in the next few years. support. Driven by the dual layers of policy and market, blockchain-related industries are expected to move from reality to reality, and blockchain technology will accelerate the exploration of possible application scenarios.
Forecast of global blockchain market size
According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in the Blockchain Industry" released by the Qianzhan Industry Research Institute, the global blockchain market size is expected to increase from 2017 to 2017. It will increase from US$411.5 million in 2022 to US$7.6837 billion in 2022, equivalent to a compound annual growth rate of 79.6%. Given the wide range of applications for distributed ledgers and the rising market value of cryptocurrencies, there is a strong need to improve transparency, security, efficiency and streamline processes, as well as blockchain as a service (
BaaS). As a hot topic of development, the blockchain market will expand rapidly. In addition, communication services, international trade, supply chain management, program platforms, payments, smart contracts, digital identity verification, etc. also urgently need blockchain technology and will create a large number of growth opportunities.
Blockchain, as an integrated application of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other technologies, has become a hot topic of research and discussion by international organizations such as the United Nations and the International Monetary Fund as well as many national governments in recent years. The industry has also increased investment. At present, the application of blockchain has extended to many fields such as the Internet of Things, intelligent manufacturing, supply chain management, and digital asset transactions, and will bring new opportunities to the development of new generation information technologies such as cloud computing, big data, and mobile Internet. , has the ability to trigger a new round of technological innovation and industrial change.
By 2022, the payment sector may occupy the largest share of the blockchain market

『Shi』What impact does blockchain have on the real economy

Blockchain has becomeIt is a new highland for global technological competition, and its technological applications extend to many fields of the real economy. Actively promoting the deep integration of blockchain and the real economy will help promote my country's industrial upgrading and achieve the goal of high-quality development. Blockchain is a new model of open innovation, a new carrier for coordinating industrial integration and a new path to promote green development. It is in line with the five development concepts of "innovation, coordination, green, openness and sharing". Although blockchain has achieved "revolutionary" technological breakthroughs, there are still some problems and challenges in practical applications.
In the early stages of the development of the blockchain industry, through "transactions on the chain", blockchain technology must realistically solve some "small problems" for the industry. Specifically, it can reduce costs, improve efficiency, and create an environment of integrity. Promote the development of the real economy in all aspects.
Blockchain will play the role of “reducing costs for the real economy”.
The current real economy has high costs and thin profits, resulting in insufficient capital support for the real economy. Among operating costs, management costs and financial costs account for a large proportion. Blockchain technology can effectively help enterprises reduce the costs of these two parts.
Blockchain will play the role of “improving the collaborative efficiency of the industrial chain”.
Enhancing industrial synergy is an important way to promote China's manufacturing to the mid-to-high end. However, in many industries, the efficiency of industrial chain synergy is still not high, and this problem is particularly prominent in the field of international trade.
Blockchain will play the role of “building an honest industrial environment”.
At present, the construction of my country's social credit system is accelerating, but in some cases, the process of establishing trust among partners is still slow, it is difficult to obtain various types of credit information, and it is difficult for small, medium and micro enterprises to obtain credit loans from financial institutions. . Through "transaction on-chain", all parties can more easily query the accurate historical credit status of counterparties, and can establish cooperation mechanisms more quickly; banks can also more safely grant credit to enterprises based on transaction records, and promote the solution of the problem of honest management. Small, medium and micro enterprises face problems such as “difficulty in financing, expensive financing, and slow financing”.
Blockchain: a new model of open innovation
Blockchain is a decentralized, distributed database system participated by various nodes. It can be understood as a public accounting mechanism (technical solution). The basic idea is to ensure the authenticity and non-tamperability of information by establishing a set of public ledgers on the Internet, and all users in the network jointly record and verify accounts on the ledgers. The reason why it is called "blockchain" is that it uses a series of data blocks generated by cryptographic methods. Each data block contains all transaction information in the past period of time, which is used to verify its information. validity and generate the next block. Complete traceability, decentralization and de-credit are the three major characteristics of blockchain technology, which give it great potential for application in the financial industry and become the core technology of financial technology. As virtual cryptocurrencies represented by Bitcoin continue to be hyped by the market, blockchain technology has attracted great attention from all walks of life. Although virtual cryptocurrencies such as Bitcoin are currently relatively mature applications of blockchain technology,, but it must be pointed out that virtual cryptocurrencies are not the only application of blockchain. The essence of blockchain is for decentralization, which is exactly the development trend of the future market.
