Blockchain applications are diversifying and are extending from the financial field to the physical field.

Reporter: The integrated application of blockchain technology plays an important role in new technological innovations and industrial changes. Which pain points of social and industrial development do you think the current application of blockchain technology can solve?

Si Xueming: At present, the application of China's blockchain is mainly concentrated in financial services and corporate services, but the application of blockchain is diversified, and it is extending from the financial field to the physical field. Specifically, first, blockchain + supply chain finance can solve the problem of financing difficulties for SMEs. The pain point of traditional supply chain finance is that the company cannot prove its ability to repay itself, and it is difficult for the bank to verify the authenticity of the transaction itself. In addition, the information between banks, core companies and suppliers is fragmented from each other, and compliance risks cannot be effectively controlled. By using blockchain technology, the trust problem can be solved through consensus algorithms, and compliance risks can be prevented through smart contracts, so that trust can be effectively transmitted along the supply chain, and the goals of reducing cooperation costs and improving compliance efficiency can be achieved.

Second, blockchain + cross-border payment can solve the problems of low cross-border payment settlement efficiency and high fees. For example, using a traditional cross-border payment platform, it takes about two weeks to achieve cross-border payment from China to Vietnam, and cross-border payment transactions using blockchain technology only take ten minutes. The blockchain solves the problem of trust through consensus algorithms, reduces the number of process steps required for business completion, improves transaction processing efficiency, and reduces business costs. In addition, it also realizes transaction information transparency and privacy security.

Third, blockchain + credit information can solve the problems of the formation of islands of credit information, the easy information tampering with centralized credit information systems, the inability to trace data, and the inability to guarantee the authenticity of shared information.

Fourth, blockchain + electronic invoices can solve the problems of traditional invoices with many participants, long circulation cycles, non-interoperability of information between participants, fraudulent invoices, and multiple invoices. The "two-in-one" of capital flow and invoice flow was realized, which opened the whole process of invoice application, invoicing, reimbursement, and tax reporting, making the entire invoice searchable, credible and traceable, effectively avoiding false invoices, and improving the invoice supervision process.

Fifth, the blockchain can realize the anti-counterfeiting traceability of commodities, thereby serving the real economy. Blockchain technology connects digital and physics. Through secure and open data, we can know the "past and present" of the product and realize "traceability". In terms of anti-counterfeiting, technologies such as big data, artificial intelligence and the Internet of Things need to be combined. For example, when consumers want to determine whether the fish they buy is wild, the first step is to encrypt the real photo of the fish and upload it to the blockchain. The second step is to use the serial code on the blockchain. Take a photo of the fish and use the "face recognition" technology to perform "fish face recognition" with the current fish to learn the authenticity of the fish.

Sixth, blockchain + certificate storage solves the problems of difficulty in obtaining evidence and litigation in the financial field. The blockchain further strengthens the immutability of evidence on the basis of traditional evidence storage schemes, and provides credible, traceable, and provable technical guarantee for subsequent evidence verification, dispute resolution, and adjudication delivery.

Seventh, blockchain + medical health can effectively solve the problems of medical data privacy protection, data security sharing, and transaction record security. At the same time, it can trace the source of pharmaceutical information, promote multi-party supervision of drugs, and prevent counterfeit drugs from entering the market. In addition, it can optimize the medical insurance claims process, ensure the credibility of data, and realize the secure sharing of information among insurance companies, hospitals, and patients.

Eighth, blockchain + security technology can effectively break through the predicament of data sharing and solve the urgent application needs of data sharing in the fields of government affairs, people's livelihood, and science.


Foshan can take the lead in exploring the combination of blockchain and big data industries to form a new industry.

Reporter: In recent years, Foshan is also actively exploring the application of blockchain technology, such as blockchain + digital government, blockchain + community correction, blockchain + financial technology, etc. What suggestions do you have for developing the blockchain industry in Foshan?

Si Xueming: I have the following thoughts on how to develop the blockchain industry: First, the introduction of a blockchain industry policy to increase industrial support. On the one hand, in light of the development of the blockchain, a special support policy for the blockchain industry was introduced, focusing on key technology research, major demonstration application projects, and blockchain infrastructure construction. On the other hand, cities are encouraged to establish supporting talent policies, preferential tax policies, rent reduction policies and innovative incentive policies.

Second, build a blockchain industry base and gather industrial ecology. First, build a blockchain technology innovation strategic alliance and promote well-known universities and enterprises at home and abroad to set up blockchain research centers. Secondly, it strongly supports the research of blockchain technology, the incubation of start-up companies, and the acceleration of growing companies. Finally, integrate the innovation elements and resources of the blockchain industry to build a model blockchain innovation ecosystem.

Third, establish a blockchain industry fund to promote industrial clusters. Through the establishment of a blockchain industry investment fund, equity and other methods are used to support start-ups and high-growth companies to become larger and stronger. At the same time, it guides and encourages various financial service institutions to increase investment in blockchain start-ups, provide full life-cycle financial services, and form a blockchain industry innovation cluster.

Fourth, develop blockchain application demonstrations to promote application landing. Establish a one-stop service platform for blockchain application supply and demand docking in the industry field, and strengthen industry blockchain service docking. At the same time, encourage the development of blockchain application demonstrations in areas such as smart manufacturing, financial technology, people's livelihood security, regulatory governance, and social services, and promote the procurement of blockchain services in government governance and public service areas.

Fifth, promote the development of blockchain standards and form an industry leader. Support standards in key areas to promote alliance construction, and promote standard development and promotion in a coordinated manner; in accordance with the principles of first use, maturity first, key breakthroughs, formulate blockchain industry application specifications and implementation guidelines; encourage enterprises to participate in international, national, and industry standard systems Revision work.

Sixth, increase the introduction and cultivation of talents and promote the development of the industry. Increase the introduction and training of international high-end blockchain talents, speed up the construction of innovative and composite talent teams that integrate blockchain technology with the industry, and rely on social education resources to develop districts through the interaction of associations, enterprises, and universities. Blockchain professional education and technical training, exporting outstanding talents for the industry.

In recent years, Foshan's exploration of blockchain + government affairs has been at the forefront of the country. On the basis of continuing to do a good job in the demonstration of government blockchain applications, I have the following suggestions:

First, establish a leading group to advance the work of the blockchain. The planning, construction, and promotion of blockchain projects are often directly related to multiple departments in the city. Especially at the prefecture and city level, if there is no dedicated leadership team for unified management, then the problem of "who to implement" for the project will be faced. At the same time, the Blockchain Research Institute was set up to make good top-level design. Due to the lack of top-level design, early e-commerce eventually became an information island, and many current blockchain platforms have failed to achieve interconnection. To avoid the old path of e-commerce, blockchain must pay attention to top-level design and planning. In addition, develop a blockchain development plan and issue a blockchain support policy. Foshan must be forward-looking and highly motivated when formulating a blockchain development plan. Due to the limited data and resources at the district level, Foshan needs to play a major role in the city when planning.

Second, give full play to the role of blockchain in social governance. For example, the application of blockchain to community correction in Chancheng District is a practical measure. At the same time, vigorously promote the application of blockchain in supply chain finance. Foshan's industrial agglomeration effect is obvious, and township enterprises are developed. A town is often an industrial chain. In this case, creating a blockchain + supply chain financial platform has an important role in the development of Foshan. In addition, actively explore the innovative application of blockchain in empowering Foshan industrial clusters. Foshan has many industrial clusters with a high degree of concentration. In addition to supply chain finance, the role that blockchain can play in other aspects can be considered. For example, can blockchain technology be used to regulate private lending? How does blockchain technology make product quality supervision more effective? The application of the blockchain cannot be simply copied, but it takes effort to innovate.

Finally, we must actively explore and play the role of blockchain in big data sharing to create a new model of data finance. Many cities today propose the development of blockchain technology and industry, but technology can be explored, but the industry is difficult to form. Foshan has made many explorations in the field of blockchain + big data. Can you consider combining the blockchain with the big data industry to form a new industry? At present, the government has a large amount of data, but these data are difficult to translate into fiscal revenue. The big data industry itself also encounters development bottlenecks because data transactions involve personal privacy, which easily leads to violations of laws and regulations. How to make full use of data without violating laws and regulations? The new model of data finance is to combine blockchain technology with big data, and the government will guide the data into the data pool for use, while ensuring that the original data will not be leaked, thereby giving birth to a new industrial model.


In the next three years, blockchain will be widely implemented in the real economy, and the new platform economy it will create will open a new era of sharing economy.

Reporter: At present, China's blockchain technology and industry are developing rapidly. What challenges and trends do you think the development of blockchain will have?

Si Xueming: At present, China's blockchain companies are mainly concentrated in first-tier cities. From the perspective of the number of blockchain companies, Beijing, Shanghai, Guangdong, and Zhejiang are the forefront; the application of blockchain is mainly concentrated. In financial services and enterprise services, financial application services mainly include cross-border payments, insurance claims, securities transactions, bills, etc. Enterprise service applications are mainly concentrated on the establishment of the underlying blockchain and infrastructure, providing data for the Internet and traditional enterprises Chain services; The application of blockchain is diversified, and blockchain technology has begun to deeply integrate with the real economy industry, forming a group of "industrial blockchain" projects, ushering in the era of "blocks of flowers blooming together" in the real economy industrial blockchain; blocks Chain technology and applications have developed rapidly, and the number of patent applications has grown rapidly. As of July 25, 2019, the number of applications for open blockchain patents globally reached as high as 18,000, and China's share of global patents accounted for more than half, which was three times the number of US patent applications.

Although China has achieved many achievements in the construction of the blockchain industry and technology research and development, the blockchain industry and application development also face many challenges. The first is the short time of technology emergence. The application of blockchain in China is basically 2016. It ’s only started; the second is that the industrial scale is still in a relatively small stage; the third is that the application of blockchain is mostly in the exploratory stage; the fourth is that the supervision of blockchain is difficult, especially the supervision of public chains, which has become a global governance The fifth problem is that there is still a gap between the parties' perceptions of the blockchain.

The future development trend of blockchain, from the perspective of application prospects: First, single-scenario applications will develop to cross-industry scenario applications. Secondly, the technological upgrade and the diversification of application scenarios promote the upgrade of blockchain application models. The initial stage of the blockchain is mainly for the 2B model of enterprises or the 2G model for governments. In the future, the blockchain will develop towards the 2C model. Third, the development of the integration of blockchain with the Internet of Things, big data, and artificial intelligence has become a trend. In the end, the blockchain will gradually penetrate from the financial industry to diversified fields such as the Internet of Things and medical health.

From the perspective of industrial development: Blockchain will become the forefront of global technology development, a new international competition track, a new land for innovation and entrepreneurship, and a new space for application and expansion. In the next three years, blockchain will be widely implemented in the real economy, and the new platform economy it will create will open a new era of sharing economy. In addition, the blockchain will also speed up the process of "trusted digitalization" and drive financial "depreciation to reality" to serve the real economy. At the same time, the blockchain supervision and standards system will be further improved, and the foundation for industrial development will continue to be consolidated.
