1. A brief analysis of the application of blockchain technology

Today we will talk about the application analysis of blockchain technology in the field of public resource transactions
Public resource transactions , including the purchase of public resources by the public sector, such as government procurement, construction project bidding, etc.; also includes the sale of public resources by the public sector, such as the bidding, auction and listing of state-owned land, the transfer of mining rights, the sale of state-owned forest rights, the sale of state-owned Disposal of financial assets and other public resource sales involving public interests and public security. Public resource transactions are related to the national economy and people's livelihood, and involve the fundamental interests of the people. Therefore, public resource transaction management has always been an important management function of my country's government affairs management.
In recent years, the National Information Center has continued to promote the construction of a public resource trading service platform, giving full play to the role of a public entrance to trading services, a public channel for data sharing, and comprehensive technical support for cross-regional transactions. The integration of public resource trading platforms based on digital technology has achieved remarkable results. Among them, blockchain technology has the characteristics of consistent data storage, difficulty in tampering, and traceability. It provides new ideas and solutions to solve the problem of trust in public resource trading data. path.

Information data management issues in the field of public resource transactions

Objectively speaking, various credit deficiencies have long existed in the field of public resource transactions in my country, which not only disrupts the normal market transaction order, but also It affects the fairness and justice of market competition, and also poses serious risks and threats to the quality of project construction and construction safety production. The reason is that the root cause of credit risk lies in the information asymmetry between entities in the public resource trading market, and in the limitations and defects of traditional public resource trading management on information data security and information data use.

Data security management issues

Various transaction information and credit information in the field of public resource transactions contain huge value. Under the increasingly electronic development trend of domestic public resource transaction management and services, including electronic bidding user identity information, potential bidder information, bid evaluation committee composition information, bid document information, judges' bid evaluation information, and bid evaluation result information Various types of information security risks have increasingly become important issues affecting the efficiency, quality, and fairness of public resource transactions.
Traditional data security technology cannot effectively avoid security management problems such as leakage, tampering, and loss of various information data. Especially with some technical means, it is difficult to trace traces of relevant data operations, causing great trouble for data security management. .
Data sharing application issues
The main reason for the long-standing problems of various credit deficiencies and untrustworthy behaviors in the public resource trading market is that there are limitations in the sharing and application of relevant credit information of market entities.
On the one hand, a large amount of credit information of market entities has been deposited in various departments for a long time and has not been fully exploited;
On the other hand, the credit information of public resource trading market entities involves banks, public security, courts, housing Construction, human resources, taxation, etc.Multiple management departments, the long-standing phenomenon of "data islands" and "data fog islands" between different management departments hinders the efficient sharing and application of credit information in the public resource trading market.
Blockchain and public resource transaction information data management
According to the "China Blockchain Technology and Application Development White Paper 2016" issued under the guidance of the Ministry of Industry and Information Technology, in a broad sense, blockchain technology is the use of blocks Chained data structures are used to verify and store data, distributed node consensus algorithms are used to generate and update data, cryptography is used to ensure the security of data transmission and access, and smart contracts composed of automated script codes are used to program and operate data. A new distributed infrastructure and computing paradigm.
Essentially, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner. In layman's terms, blockchain technology can be seen as an accounting method that supports the participation of all people.
Traditional data accounting involves multiple accounting entities and generates multiple data ledgers. Under this accounting method, due to the risks of lack of supervision, technical security risks, and physical security risks, the account data may be tampered with or lost, and it is difficult to trace relevant operational behaviors. Therefore, the objectivity, fairness, and security of the account data must be It’s hard to guarantee.
Blockchain technology provides a technical solution that supports multiple accounting entities to participate in accounting. When any accounting subject modifies the ledger, its modification behavior will form indelible traces (timestamps) in the ledger records, and the modification results will be synchronized to the ledgers of all accounting subjects, which prevents the account from being The risk of data tampering and loss can be traced back to relevant accounting behaviors to promote supervision.

In response to the information data management and credit issues raised above in the field of public resource transactions, blockchain technology can use its own "decentralization", "distributed data storage" and "traceability" ”, “anti-tampering characteristics”, “openness and transparency” and other advantageous features to effectively respond and solve.
Public resource transaction data is tamper-proof
The public resource transaction platform stores a large amount of public resource transaction data. With traditional centralized data storage management, once the data and backup are damaged or lost, it is difficult to recover, and due to There are loopholes in the supervision mechanism and the risk of data tampering.
Blockchain technology adopts "decentralization" and "distributed data storage". Data damage or loss in one or more data storage nodes will not affect the data security of other data storage nodes. At the same time, updates to data ledger records are shared and made public simultaneously, and operations traces are supported. Blockchain data cannot be tampered with or corrupted unless all nodes are compromised.
Establishing a trustworthy public resource transaction data environment
Information asymmetry in the public resource transaction market leads to adverse selection and moral hazard among market entities, affecting the efficiency and quality of public resource transactions, and affecting the orderly operation of the public resource transaction market. hairexhibition.
Blockchain technology solves the problems of authenticity, security and openness of public resource transaction data, promotes the efficient sharing and application of credit information in the public resource transaction market, promotes the establishment of a trustworthy data environment for public resource transactions, and prevents and avoids Various credit risks provide trustworthy data decision-making support for market transaction entities and regulatory entities

2. What are the applications of blockchain industry

Take the tourism industry as an example. Chain applications are mainly concentrated in the application fields of travel, travel community reviews, digital identity management, credit consumption management, tracking pilots’ professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumption points management. In addition, with the development of blockchain, many related top domain names have been registered, which has had a relatively large impact on the domain name industry. In addition, blockchain also has applications in finance, games, entertainment and other fields.

3. In addition to donations, what else can blockchain public welfare do?

With the urgent shortage of resources, major Internet companies have taken various actions to actively rescue areas with severe epidemics such as Wuhan. . In this rescue operation, we also saw that some blockchain companies are also taking active actions. Incomplete statistics show that as of now, blockchain traders include Ant Financial, Du Xiaoman Finance, Qulian Technology, Huobi, Ouke Group, Zhen Fund, Quantum Chain Foundation and other blockchain-related companies. Donation: Du Xiaoman Financial On January 27, Du Xiaoman Financial announced on Weibo that it would invest 10 million yuan in cash to the Internet Epidemic Special Fund to fully support the series of efforts to fight the epidemic.

Ant Financial On January 27, Alipay and Ant Insurance, a subsidiary of Ant Financial, set up a "health insurance fund" for medical staff across the country, which can be used in public hospitals of secondary level and above or designated treatment centers designated by the National Health Commission. All medical staff in institutions participating in the fight against the epidemic can receive it. After successful receipt, during the epidemic period announced by the National Health and Medical Commission, if medical staff are unfortunately infected while fighting the epidemic, they can apply for a 100,000 yuan security fund after diagnosis; if they unfortunately die due to illness, they can apply for a 500,000 yuan security fund. Medical staff search for "Ant Insurance" blockchain traders on the Alipay APP homepage and enter the page to claim it. The function of claiming on behalf of family members and colleagues is currently under development.

Qulian Technology According to the Qulian Technology official account, after the Wuhan New Pneumonia Prevention and Control Headquarters issued an announcement on accepting social donations on January 25, Qulian Technology donated 100,000 N95 medical masks. Sent to 10 hospitals including Wuhan Youfu Hospital, Wuhan Xinzhou District Traditional Chinese Medicine Hospital, and Central Theater Command General Hospital (Wuchang Park). Binance’s Changpeng Zhao tweeted that Binance has pledged to provide 10 million yuan ($1.5 million) to help people infected with the novel coronavirus in Wuhan. Changpeng Zhao said: "We have not issued any statement. However, the Binance Charity Foundation and the Binance team have been very busy in recent days. We still need help with local logistics arrangements." Huobi tweeted on January 27 BoIt was announced that Huobi Charity, a subsidiary of Huobi Group, will donate 10 million yuan for global procurement of medical supplies. Huobi said the first batch of medical supplies, 20,000 3M protective masks, has arrived in Hubei and Hunan. In the next 1-2 days, 200,000 sets of medical protective materials will be delivered to areas with severe epidemics. At the same time, Huobi collects information on the shortage of front-line supplies from netizens from all walks of life, saying that it will provide it to those in demand as soon as possible! Ouke Group On January 27, Ouke Group established a special fund of 10 million yuan for epidemic prevention and control, and joined hands with the China Charity Federation to support front-line protection work. According to insiders, the donated funds will be used for the purchase of medical supplies and the payment of pensions to frontline medical staff. At the same time, Ouke Group has mobilized staff at home and abroad to purchase materials around the world, and the first batch of medical supplies has been shipped to the areas hardest hit by the epidemic. Public chain project TOP Network On January 27, Wuhan Fifth Hospital successfully signed for the first batch of medical masks donated by the blockchain public chain project TOP Network, totaling 6,000 pieces. On January 23, after TOP Network learned about the shortage of medical supplies in Wuhan, it immediately decided to donate medical masks to Wuhan and mobilized the community to actively contribute to the disaster area. Due to the lack of medical supplies, TOP Network also helped multiple blockchain charitable organizations purchase tens of thousands of N95 masks. Qtum Quantum Chain Qtum Quantum Chain Foundation announced that it will donate 200,000 yuan to the Hubei Charity Federation for virus epidemic prevention and control. The Quantum Chain Foundation stated that the donated funds will be used to purchase epidemic prevention materials, family pensions for those who died due to the epidemic, volunteer insurance, protective equipment and living allowances. ZhenFund According to official news from ZhenFund, on January 26, 2020, ZhenFund announced the completion of a donation of RMB 2 million to the Hubei Charity Federation. Zhen Fund stated that we hope that through our humble efforts, we can help the Hubei Provincial Anti-epidemic Department purchase more urgently needed medical supplies, treat more patients in need of help, and contribute to the fight against the epidemic. The medical workers on the front lines send our condolences and solidarity. We will continue to pay attention to the development of the epidemic and are ready to work with people from all walks of life to contribute more to the fight against the epidemic. According to Krypton Capital, Maggie Wu of Krypton Capital launched the “Blockchain Charity Organization” blockchain trader. Currently, more than 50 people have participated. It has raised 45,000 USDT (approximately 300,000 RMB) in charity donations and donated funds to the world. Purchase medical supplies from various places. Besides donating, what else can blockchain companies do? During this epidemic, from the initial issue of information disclosure to the transparency of the entire donation process, the "trust machine" of blockchain can actually be used. The transparency, non-tamperability, anonymity, traceability and other characteristics of blockchain are naturally suitable for the charity industry. Now, many charitable organizations have tried to join forces with enterprises. Ant Financial Charity uses blockchain technology to track fundraising and establish third-party disclosureThe system's blockchain fund flow disclosure facilitates data statistics and project execution tracking for public welfare organizations; Beautiful China joins forces with JD.com to implement blockchain-based material donations to schools in remote mountainous areas; Tencent's public welfare search uses the multi-node alliance chain Deploy blockchain traders to link WeChat, 404 family search, baby home and other systems to achieve information exchange. This epidemic originated from some people eating wild animals. After this epidemic, people should pay enough attention to food safety. The fundamental reason for the frequent occurrence of food safety incidents lies in the opacity and asymmetry of information between the government, enterprises, sellers and final consumers. At the same time, different accounting methods are used in planting, production, transportation, storage, sales and other links, resulting in very poor food traceability. Blockchain technology promotes the further improvement of the food safety traceability system. Through the tamper-proof distributed ledger technology combined with the Internet of Things and other technologies, the entire process of food can be traced from source information collection and recording, production and processing, warehousing and logistics. At the same time, blockchain technology brings third-party regulators and consumers into the regulatory system, breaking information islands and achieving process transparency to a certain extent.

At present, Internet companies such as JD.com, Suning, Internet, and Alibaba have begun to deploy blockchain traceability systems, and some startups are also targeting the blockchain traceability market. If we establish a complete food traceability system, people can easily check the source when buying food, which may prevent such incidents from happening again to a certain extent. However, all technologies are not omnipotent, and preventive behaviors are ultimately implemented by people. Special reminder: The number of cases of pneumonia caused by the new coronavirus continues to increase. Readers and friends should try to avoid gatherings during the Spring Festival, wash hands frequently, wear masks in public places, drink more water and rest

4. Blockchain in China What are the practical applications?

1. WeBank uses blockchain technology for loan settlement
WeBank and Shanghai Huarui Bank have put into trial operation an inter-bank alliance based on alliance blockchain technology The loan clearing platform is used to optimize the settlement and liquidation of the "Weilidai" joint loans of two banks. With the introduction of this blockchain system, all information is recorded on the blockchain network and cannot be tampered with. It is liquidated simultaneously during the transaction process, achieving real-time liquidation and saving a lot of manpower and material resources. This is the practical application of "consortium chain".

2. China UnionPay uses blockchain technology to realize inter-bank point redemption
China UnionPay and IBM are trialling a shared points system using blockchain technology. The use of this blockchain system allows users to redeem reward points across banks and platforms. That is to say, a user's points in one bank can be exchanged for points and rewards from other banks, or even multiple airline miles and supermarket rewards. The efficiency of using bank points has been greatly improved.
3. Toyota uses blockchain technology to track auto parts
Toyota joins the R3 Alliance and uses blockchain technology to store the production, processing and usage of each part in the blockchain. In this way, in the car zeroWhen there is a problem with a part, you can quickly and easily check the source of the part.

5. What are the service applications that use blockchain technology?

Blockchain technology has a distributed ledger that cannot be tampered with, ensuring the transparency and sharing of information, thereby making business activities The cost of establishing trust and reaching consensus between peers has dropped significantly. This article provides an in-depth interpretation of four typical business scenarios: supply chain finance, commodity traceability, technology and medical care, and industrial Internet.
1. Blockchain adds supply chain finance. Today, the supply chain of most commodities, from the provision of raw materials to the manufacturing of finished products, involves several upstream and downstream small and medium-sized enterprises; and these enterprises are faced with the challenge of unlocking supply chain working capital. pressure. Supply chain finance refers to banks and other financial institutions making systematic financing arrangements for all member companies of the supply chain, thereby forming a win-win situation for core buyer companies and suppliers: the buyer optimizes working capital, and the supplier generates additional operating cash flow, thus Minimize risk throughout the supply chain. There are three pain points in traditional supply chain finance: 1. Information cannot be shared, efficiency is low, and credibility is poor; 2. Bill circulation is inconvenient, contract settlement is slow, and there are often financial risks; 3. Credit cannot be transferred and financing is difficult. The blockchain can realize the following functions: 1. Sharing transaction data, receivables and payables data among core enterprises, multi-level suppliers, and financial institutions while protecting commercial privacy; 2. Transfer of corporate claims and automatic settlement of funds, accelerating corporate recovery. Payment and repayment; 3. The core enterprise's payment commitments flow among multi-level suppliers and financial institutions to convey the core enterprise's credit.
2. Blockchain traceability In the field of commodity traceability, blockchain and Internet of Things technology are combined to trace the entire process of commodity circulation to prevent unscrupulous traders from taking advantage of the information asymmetry in the commodity chain to produce counterfeit and inferior commodities. NextCharge well. This prevents certain participants from tampering with data or falsely claiming that information is lost when circumstances are detrimental to them, making it difficult to provide evidence and pursue accountability. In addition, blockchain traceability can open up information islands in different links of the supply chain and improve the collaboration efficiency of the supply chain.
3. Blockchain helps medical services Blockchain technology can open up multiple links such as hospital prescription issuance, pharmacist review, drug distribution, drug payment, and process supervision. Through blockchain distributed storage and accurate matching of information on the chain with patients, the one-time dispensing effectiveness of prescriptions is ensured, prescription modification or abuse is prevented, and supervision is facilitated. In the future, patient information, prescription information, drug circulation information, etc. will be encrypted and desensitized through blockchain technology, which can open up more medical application scenarios.
4. Integration of Blockchain and IoT Industrial Internet At the 5th World Internet Conference, the supET Industrial Internet platform, which integrates Internet of Things and blockchain technology, was selected as the world's leading Internet scientific and technological achievement and became the only The award-winning industrial Internet platform.

In addition, blockchain data sharing, blockchain judicial chain, blockchain charity, trusted digital content copyright services, etc. In industries such as government, finance, industry and logistics, healthcare, retail and the Internet, blocks have a wide range of business application scenarios.

6. The first blockchain service platform in the State Grid Gansu Electric Power Company system was successfully registered

On June 7, the State Grid Gansu Electric Power Company applied for registration of the "Large Energy The "Enterprise-level Blockchain Underlying Service Platform" (hereinafter referred to as "Longneng Chain") has been submitted to the National Internet Information Office for approval after many rounds of information improvement and filing. This service platform is the first blockchain service platform in the Gansu power system to receive a registration number.

For a long time, State Grid Gansu Electric Power Company has conducted in-depth research under the overall framework of the "State Grid Chain" to implement the State Grid Corporation's work arrangements on building a "State Grid Chain" and based on consensus Mechanism, smart contracts, cross-chain collaboration and other aspects have formed its own core technologies, and developed a blockchain service platform suitable for the company's business applications. The blockchain service platform includes 1 platform and 3 centers, supporting business applications in eight major application scenarios: "energy distribution, power trading, marketing services, corporate management, finance, material supply, data assets, and electric vehicles". According to the "Blockchain Information Service Management Regulations" and the "Network Security Law of the People's Republic of China", blockchain information service providers engaged in blockchain information services within the territory of the People's Republic of China must register in the National Blockchain Information Service Registration Management System Authentic information verification will be carried out. After the registration information is reviewed by the Cyberspace Administration of China, a unified registration number will be issued and a formal announcement will be issued.

The completion of the filing procedures and the successful filing are recognition of the legal compliance of State Grid Gansu Electric Power Company in engaging in blockchain business, laying a solid "cornerstone" for the standardized operation of the "Long Energy Chain". Propping up the "beams" and playing a positive role in the subsequent development of blockchain businessThe role of guidance provides an authoritative reference for the industry and government agencies to dare, want to use, and be willing to use the blockchain service. Successful filing is the first step in the compliance development of Tongxing Intelligent's blockchain business. This step has laid a good foundation for continued work such as expanding the blockchain business and applying for national blockchain innovation pilots.

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

With the development of regional With the continuous development of blockchain, the application coverage of blockchain is getting wider and wider. With the improvement of scalability and efficiency, the application scope of blockchain will go beyond the financial field and expand to fields such as logistics, real estate and the Internet of Things, becoming It is the lowest-level protocol in future society, which means that 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 2.0 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

Corresponding to the upper, middle and lower levels of the industrial chainThe upstream includes: upstream underlying technology and infrastructure (core technology, equipment, underlying platform deployment methods); the midstream service layer mainly provides developers with applications based on blockchain technology; the downstream application layer includes finance, supply chain management, and 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 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. 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 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 been used in many applications in supply chain finance, stock trading, banking, etc., and I will not 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 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.

As an architectural innovation technology, blockchain has a huge demand for comprehensive talents, requiring those engaged in it 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?
