Di Gang: The Beijing Olympic Winter Games digital renminbi demo program has been stable and prominent.

The world has entered the phase of rapid integration and development of digitization, and the role of digital technology has been recognized throughout the community and has grown rapidly in the financial sector. Now in the age of digital intelligence, our relationship with the real business has evolved from advocacy, support and encouragement to integration, knowledge and development. On December 5, at the 18th International Conference of the International Financial Forum (IFF), Di Gang, Vice President of Human Resources Digital Financial Institution The Bank of China, said:

Di Kang pointed out that in March this year, Korea announced the "14th Five-Year Plan" and "Long-Term Goals for 2035". We must promote and support intelligence, big data and blockchain. , cloud computing, network security and other digital marketing. “Among the digital technologies we focus on, blockchain technology has become an important driver in the development of digital finance. "

In fact, blockchain technology has been widely used. According to Di Gang, in 2021, consulting firms will conduct blockchain research in 10 countries, including the US, UK, Singapore, Germany, China and Japan, and 81% of interviewers believe as blockchain technology has emerged. There is a lot of potential. scalability and adoption by major companies, 84% of which have been approved by financial companies. Each global financial company surveyed as a blockchain is the largest in the industry. In September 2021, a research institute studied blockchain applications from the world's top 100 catalogs, and 81 organizations were found to be using blockchain technology.

Blockchain technology is starting to be used in the digital industry. Di Gang, meanwhile, points out that from patent competition to combat, seeking circumstances to create security, the benefits of using blockchain continue and increasingly positive results have been achieved. In the areas of cross-border technology, financial exports, agricultural finance, financial economics, inclusion, urban relations, "agriculture, rural areas and farmers", human health and other industries, some financial companies around the world are still developing the blockchain application scenario. and yes. , financial trade, information sharing, foreign trade, fair trade, etc.

Di Gang focused on using blockchain technology in the math department. He noted that Digital Labs was the first organization to explore blockchain applications in R&D activities.

One is to create an integration of applications based on blockchain technology into the digital renminbi system. As a trusted business, the central bank keeps the exchange information on-chain to ensure the accuracy and reliability of the data.

The second is the implementation of a number of digital currency banking companies with the Company's support at the International Settlements Innovation Center. The School of Mathematics is leading a team working on the Digital Currency Bridge project, exploring how to create a value-added bridge testing platform using distributed data.

The third is to become a leader in the completion of the key tasks of the national key research and development plan to develop the financial blockchain platform and complete the construction of the blockchain as a financial financial ecosystem with the aim of 'access information and trust. , credit sharing.

Fourth, in the area of ​​standardization, the Mathematics Institute actively supports the design process, led the development of several international blockchain models, and served as vice chairman of the National Blockchain Distributed Ledger Accounting Standards Committee. The process using blockchain technology and other national standards has been developed, and with the support of the Golden Industry Commission, the development of industry relevant standards such as blockchain monitoring policies, special security, communications, financial markets, etc.

Digang believes that the current blockchain faces six major challenges in digital finance. He pointed out that although blockchain technology has expanded the various applications in the digital financial world, it still faces challenges.

On the other hand, in terms of system architecture, there are still many performance and scalability issues, so we need to pay attention to solutions like sidechain, multi-chain, hardware acceleration, on-chain and off-chain collaboration.

Second, regarding the protection of personal information, "the current importance of protecting personal information such as zero authentication, homomorphic encryption, multi-party security, and education in government has major limitations. The same goes for engineering and technique, ”said Di Gang.

When it comes to information security, Di Gang believes that the blockchain faces issues such as self-regulation, open source space and quantum counting, and needs to strengthen innovation in security technology, including smart contracts, authentication, security contracts and decentralized DID.

In addition, in terms of monitoring and surveillance, Di Gang believes that many nodes of the blockchain are anonymous and hidden, the classification is difficult to monitor. .

In terms of integration, “the integration and compatibility of blockchain and traditional technologies need to be strengthened, and there is conflict. There is a need to further strengthen the research focus on the implementation, development, integration and development of blockchains based on modern technology. old new urine, ”said Di Gang.

Finally, speaking of the process, Di Gang bluntly said that the blockchain integration was poor, the process was critical, and the design was inadequate.

From D. Kang's perspective, blockchain digital finance offers room for future developments in theory, technology, core technology, and specialization.

For example, in terms of theoretical theory, Di Gang believes that scientific research should be encouraged. The cultivation of technology is often faster than the advancement of technological theory. Need to upgrade technology to the latest architecture technology, reliable technology. In terms of consensus algorithms and cryptographic thinking, core, technology, the development of technology includes new smart contracts, blockchain network technology, chips and repair hardware, including chain links, monitoring , threat monitoring, etc.

Di Gang pointed out that the People's Bank of China Digital Currency Research Institute is a direct public organization within the People's Bank of China. It focuses on building a nation of legitimate digital advantages, innovation and financial reform. “The digital yuan is expected to be launched by the end of 2019 and it has been tested in 10 regions and at the Beijing Winter Olympics in 2022. In July this year, The Bank of China company announced that the Pilot digital yuan currency, an integral part of Olympic preparations, will continue to operate on site for the Beijing Summer Olympics.
