2. Multiple types of data are shared on the "chain", online and offline services are coordinated, and blockchain government affairs make things easier.

What kind of sparks will “blockchain + government affairs” collide with? Mawei Xingang Community in Fuzhou City, Fujian Province uses blockchain technology to solve the pain points of government informatization and launches a "blockchain + community certification" application. "This application can easily realize the electronic issuance of certificates required by enterprises and the masses, promote the transformation from 'reduced certificates' to 'no certificates', let data run instead of people running errands, improve service efficiency, and better serve the people. "Ms. Zhu, a citizen of Fuzhou, said.

Provident funds can be transferred and continued in other places

"Post-90s" Chen Jing joined a new company at the end of last year, and her work location changed from Hangzhou, Zhejiang to Chengdu, Sichuan. If you change your workplace, how can you transfer the previously accumulated housing provident fund to a new account? After consultation, Chen Jing learned that by searching for the "National Housing Provident Fund" applet on her mobile phone, she could realize the transfer to other places. According to the relevant person in charge of the Ministry of Housing and Urban-Rural Development, the "National Housing Provident Fund" applet will be launched online in October 2021. The Ministry of Housing and Urban-Rural Development has built a credible data environment for the operation of the applet by deepening the application of new technologies such as blockchain to ensure that depositors information and financial security. Thanks to blockchain technology, depositors can transfer housing provident fund accounts and funds across cities through mini programs. They no longer need to go to the counter to handle off-site transfers and continuations, which greatly shortens the processing time and further facilitates the cross-regional flow of human resources. .

Multiple types of data are shared on the "chain", online and offline services are coordinated, and the use of blockchain technology improves the efficiency of government departments and public satisfaction. For example, Haidian District in Beijing has opened a "Blockchain Zone" on the Haidiantong APP, which can directly handle public rental housing subsidies, Haidian District high-tech talent training subsidy approval, etc... With the application of new technologies such as blockchain, many government affairs The service realizes "one-stop service and full online service".

In addition, Zhuzhou City in Hunan Province has also innovated administrative approval service methods and launched blockchain application scenarios for electronic certificates, effectively improving the level of government data sharing and business collaboration efficiency; Fuzhou City has launched the "Rongcheng on the Chain" plan , exploring the use of blockchain technology in four fields including e-government, financial technology, social governance, and people's livelihood security.

Why does the government field favor blockchain technology? Industry insiders believe that blockchain technology has the characteristics of non-tampering, security, confidentiality and traceability, and is highly suitable for government service needs such as cross-domain data sharing and business collaborative management. Active use of blockchain technology can solve the problem of data sharing in the government service process. problems such as difficulty in solving problems and difficulty in business coordination, and improve government management services and coordinationCoordination.

Effectively supporting people’s livelihood services

Related management service platforms based on blockchain in many places in China have been launched frequently: in Jiangsu, the country’s first transfer of idle residential use rights based on blockchain technology The transaction was successfully completed. Relying on the provincial information service platform, the transaction information can be directly uploaded to the "chain" for certificate storage, ensuring that the housing source is credible and the results are traceable; in Zhejiang, the first intellectual property blockchain public certificate storage platform was officially launched, providing data Assets, original designs and other intellectual property rights provide efficient and fast certificate storage services; in Yunnan, the Provincial Market Supervision Administration and the Provincial Key Laboratory of Blockchain Application Technology jointly carry out Yunnan Province’s blockchain underlying chain food traceability work based on domestically produced independent , through blockchain technology, we can promote product source traceability, one-stop code, logistics tracking, responsibility identification and credit evaluation, so that blockchain technology can truly contribute to people's livelihood services.

Hu Kai, a professor at the School of Computer Science at Beihang University, told this reporter that the current blockchain industry applications are mainly divided into four categories: real economy, financial services, social governance and people's livelihood services. The government attaches great importance to guiding blockchain The application of chain in manufacturing, energy, government affairs, education and other fields has been implemented.

Active drive at the policy level has allowed blockchain to continue to advance in industries such as judicial evidence storage and transportation and shipping data sharing. In May, the Supreme People's Court issued the "Opinions of the Supreme People's Court on Strengthening the Judicial Application of Blockchain", proposing that by 2025, a blockchain alliance for interoperability and sharing between people's courts and all walks of life should be established to form a relatively complete blockchain judicial system. Field application standard system. In June, the Ministry of Transport issued the "Guidelines for the Construction of an Electronic Platform for Imported Dry Bulk Cargo Entry and Port Business Based on Blockchain" in June, proposing to promote the in-depth integration and development of blockchain technology and the transportation industry.

Let data flow safely and orderly

Hu Kai believes that today, with the rapid development of the digital economy, numbers and data are key elements for future social development, but there are still legal issues behind the data. , interoperability, privacy, security, traceability, storage, transactions and many other complex issues. How to make data flow more securely and orderly? Blockchain technology has broad room for development.

Blockchain technology is accelerating breakthrough applications and playing a role in establishing a trustworthy and secure digital economic order and promoting high-quality economic and social development. The China Academy of Information and Communications Technology released the "Blockchain Infrastructure Research Report (2022)" in July this year, proposing that as the scale of blockchain infrastructure construction continues to expand and operating capabilities continue to increase, blockchain can not only be used in encrypted digital Currency and other scenarios can also be applied in manufacturing, service industries and other fields. Typical application scenarios such as digital collections, data circulation, supply chain finance, and product traceability have emerged.

3. In what fields can blockchain be applied?

According to incomplete statistics from Capital Lab, there will be a total of 1,290 global blockchain application cases in 2021. The number of cases is the same as in 2020Compared with 1304 in 2017, the number was basically the same. These cases cover three major application types: financial applications, government applications and industry applications. Among them, financial applications accounted for 25% and government applications accounted for 12%; except for the financial industry, applications in other industries accounted for 63%. Blockchain technology is accelerating its expansion into the industrial application market.
Take the blockchain unicorn company Qulian Technology as an example. Qulian Technology’s products are widely used in key fields such as finance, people’s livelihood, government affairs, justice, energy, manufacturing and other key fields. With 180+ typical applications, it is the industry leader. The blockchain enterprise with the richest implementation scenarios.

4. What signals does the blockchain 3.0 era give us

In 2020, blockchain was included in the category of "new infrastructure" by the country, and at least 7 provinces introduced it Blockchain support policy. In the same year, blockchain technology was gradually moving from concept to implementation, with many application scenarios blooming. Various industry applications of "blockchain" 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.

At present, blockchain is cross-innovating with new technology infrastructure such as cloud computing and artificial intelligence. More and more vertical fields of the real economy are showing the development pattern of "blockchain" and the "elimination trend". "real" good momentum.

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, various industrial application scenarios of "blockchain" 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 2020In October this year, more than 262 listed companies were involved in the blockchain field, coming from 39 fields including insurance, real estate, commercial department stores, security equipment, packaging materials, and telecommunications operations. 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, and supply. Applications in 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 show a trend of coordinated development in multiple fields. 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 the efficiency of upstream and downstream industries.Collaborate to 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 sales 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 show a positive development trend in terms of policy support, ecological construction, platform services, application implementation, and integrated innovation.
