A. Who knows if real estate transactions on the ETE blockchain are reliable?

You can rest assured that the real estate transactions on the ETE blockchain are very transparent and safe!

B. Popular explanation of what blockchain is

Question 1: What is blockchain? Can you explain the principle of 10-point blockchain in plain language: Go Centralized 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. The tamperer needs to modify more than half of the system sections at the same timePoint data can truly tamper with data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system.
?
1.2 Why is there blockchain innovation?
Human beings need to communicate during their activities, and communication is based on information. In the past, information circulation was not convenient enough to satisfy market participants. There is a demand for information, so intermediaries and centers are born. This centralized system has problems such as high cost, low efficiency, value dispersion, "information islands" and insecure data storage. However, due to technical and environmental factors, this system continued to operate for many years until the emergence of the Internet. The starting point of the first generation of the Internet is the TCP/IP protocol, which is an open code that implements a unified format for peer-to-peer transmission of information by all nodes on the network, and brings the basic values ​​of freedom and equality required by a global unified market into programmed, protocol-based, and reliably Execution. The Internet eliminates low-value, high-cost intermediate chains and achieves low-cost and high-efficiency global information transmission in a decentralized manner.
?
However, the first generation of the Internet did not solve the problem of information credibility. Activities that can be decentralized on the Internet must be activities that do not require credit endorsement, and activities that require credit guarantee must be activities involving centralized third-party intermediaries. Therefore, Internet technology that cannot establish global credit has encountered great obstacles in its progress - people cannot participate in any value exchange activities on the Internet in a decentralized manner. To realize value exchange, people still need third-party intermediaries based on credit (such as banks, clearing agencies, exchanges). The global centralized credit system still has problems such as high operating costs, low efficiency, and vulnerability to attacks and damage. For example, each country's legal currency has different credit values ​​and incompatible clearing systems, which adds a lot of cost to global trade.
?
Therefore, what the second generation Internet must break through is: how to establish global credit in a decentralized manner? Let...>>

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

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

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

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

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

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

Question 8: Easy to understand Explain clearly what is blockchain. The English name of blockchain is Blockchain. Block literally means block, block, and chain means chain, chain. Therefore, together they are translated into blockchain.
1. Use cryptography technology to carry outEncryption and decryption make records unable to be tampered with. Common blockchain encryption methods include hash algorithm, RSA algorithm, elliptic curve algorithm, etc.;
2. The huge amount of calculation needs to be supported by a reasonable reward mechanism. Because every transaction must be recorded, Bitcoin’s blockchain has more than 60 gigabytes so far. Every new transaction requires confirmation of the information related to the trading account to ensure that the transaction is valid. The huge amount of calculation requires a computer with powerful computing power to complete.
In order to encourage the participation of powerful computing power, Bitcoin provides two rewards: one is to issue a certain number of Bitcoins to these computers every day; instead, all transfer fees are awarded to these computers. (The technical term for these computers is "mining machines", and the people who hold the mining machines are called "miners".)
Biying China is working hard on the digitization of assets and has launched the digital currency crowdfunding platform Biying China.

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

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

C. Blockchain product ownership confirmation and purchase process

1. First, the buyer visits a blockchain digital asset trading platform to find the blockchain digital collection of interest .
2. Secondly, the buyer selects the blockchain digital collection that he is interested in and purchases it.
3. The trading platform then transfers the blockchain digital collection purchased by the buyer to the buyer's blockchain account.
4. The final buyer pays the handling fee to the trading platform, and the trading platform completes the transaction between the buyer and the seller.

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

With the continuous development of blockchain, the scope of blockchain application coverage More and more widely, 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, which means As the blockchain will enter the 3.0 era.

The blockchain 1.0 era is represented by BTC (decentralization concept), and moreIt functions as a kind of distributed accounting 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 2.0 represented by ETH is a great progress, but there are still many problems, such as channel congestion, slow transaction speed, and fork risk. High handling fees and so on. 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, and provides smart contracts, information security, data services and other products based on the underlying technology. services to improve the convenience and scalability of developers developing applications at the platform layer.

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 information exchange in the era of Internet of Everythingnetwork. 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. The medical data sharing and exchange system developed using blockchain technology uploads encrypted medical data, allowing data to be shared and circulated quickly, efficiently and securely between patients and medical institutions, effectively simplifying the management of medical data. Call process to provide data guarantee for accurate diagnosis of illness.

(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 such as 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 smallest technology 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 official has put forward very high requirements for the theoretical technology and subsequent application development of blockchain technology. Do a good job in basic theoretical research on blockchain, Focusing on conquering a number of key core technologies and truly shouldering 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?

E. How to apply blockchain technology in the real estate industry

1. Financing through asset tokenization, but it is not yet compliant in China;
2. Through blockchain Chain technology realizes cost management,It can make the quality traceable and the contract cannot be tampered with;
3. Disintermediation of the transaction link is achieved through the chain, but it is difficult to do it in one step. It starts with weak intermediation and then gradually evolves to disintermediation;
4. For the rental market, consumer rewards can be provided through token design.

F. What are the applications of blockchain in social security fee collection and real estate transactions

On March 24, the "On Further Deepening" issued by the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council "Opinions on Tax Collection and Administration Reform" 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.

G. What impact does blockchain have on real estate?

Blockchain may affect the real estate market in five aspects.

To understand how blockchain could improve the real estate market, five members of the Forbes Real Estate Council measured its impact and concluded with the following:

1. Accelerate the transaction process

Using blockchain tokens, there is no need to go through property rights investigations or middlemen to protect property rights transfers. By using a blockchain distributed database to prove the authenticity of transactions, household owners can quickly transfer property rights without the need for third-party verification. The technology could revolutionize the real estate industry by making escrow companies obsolete.

2. Increase transparency

One of the biggest costs of real estate transactions is the lack of transparency, and another is transaction friction caused by too many middlemen (think escrow , insurance companies, brokers). Blockchain enables all transactions to be conducted peer-to-peer without the need for middlemen, and all information records are completely transparent. This leads to efficiency and trust.

3. Protect online data storage

In addition to cryptocurrencies, blockchain technology can also protect online data storage. In the future, it can be used to store all property records, such as title, apartment, land survey, property chain, etc. Blockchain may eventually become part of multiple listing services systems. Uses beyond cryptocurrencies will become widespread.

——Roger Blankenship, Flipping America

4. Cost-effective and trustworthy

Blockchain will eliminate dependence on title insurance and increase Transaction efficiency and confidence. It can also add transparency to the entire buyer platform, making financial considerations like difficulty affording attorney fees less of a factor in understanding title and ownership issues.

——Susan Tjarksen, KIG CRE LLC

5. Publicly provide important information

Gordon Gekko said personally, “The most valuable thing I know The commodity is information”. Blockchain will become a repository of information. A lot of information, once entered properly, can be valuable. When institutions have good information, and that information is public, risk is greatly eliminated for all counterparties who have trading relationships with those institutions.

The information comes from the Internet, I hope it can be helpful to your question.

H. Why blockchain is needed for second-hand house transactions

With the rapid development of Internet technology, second-hand house 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.
