Exclusive interview with hebaohong, director of cloud computing and big data Research Institute of China Academy of ICT: Chengdu's blockchain industry development should combine local advantages

        "2020 Chengdu global innovation and entrepreneurship fair — the first international blockchain Industry Expo (hereinafter referred to as 2020 innovation and entrepreneurship Fair)" was held from October 29 to 30. The conference selected the theme of blockchain for the first time, taking "linking ecology and creating a new future" as the theme of the conference, focusing on the current situation and trend of blockchain technology development, linking various resources of the blockchain, and creating a development ecology of the blockchain industry. Recently, as a guest speaker invited to attend the 2020 innovation and entrepreneurship fair, hebaohong, director of cloud computing and big data Research Institute of China Academy of information and communications, accepted an exclusive interview with the reporter of daily economic news (hereinafter referred to as NBD) and shared his views on the development of block chain industry in Chengdu.
        Although in theory more than 51% of the nodes in the blockchain can be tampered with, this is difficult to achieve in real life. For example, in the public chain, the number of distributed nodes is very large. It is impossible to master more than half of the nodes at the same time. In the license chain that may be applied to a specific scenario of an enterprise, the consensus mechanism requires complete consistency. Although there are not many participating nodes, all (nodes) must agree to the admission of a new party or the entry of data. This is not 51%, but 100% of the nodes agree. For example, three of us do business, but only two of us agree, which is certainly not feasible in reality.
        Therefore, compared with the traditional centralized accounting mode, blockchain has higher security. At any time, technology is a double-edged sword. Using distributed and decentralized methods to achieve tamper resistance will be more complex than centralized methods, and this complexity will inevitably bring some new security risks. At the same time, blockchain applications are used by multiple entities to maintain data. The operation mechanism of this mode is brand-new. It takes some time to learn and explore how to improve the relevant mechanisms. On the one hand, it will inevitably bring some new security risks. From this point of view, the security problems of blockchain can be divided into two categories. One is at the level of blockchain infrastructure. Its security problems are not very different from traditional security problems, and can be solved by using traditional means.
        However, there are some new things in the upper application and the security problems brought by these new things, which need special innovative research and treatment. In the past two years, the security problems related to blockchain have mainly focused on smart contracts and some problems caused by imperfect consensus, rather than the underlying infrastructure. Therefore, the government and enterprises need to make some innovations to solve the security problems of blockchain and use new means to solve new problems. In particular, the government needs to consider from the application level how to ensure data security when multiple nodes jointly maintain and manage data. At the same time, although blockchain is only used as a technology in the short term, it will inevitably have an impact on the social structure in the long term. This also requires the government to pay close attention to the development of blockchain, constantly improve the regulatory system and process, and there will be a process of running in between legal supervision and technology.
        NBD: when Chengdu will build blockchain application demonstration scenarios in the future, which fields or scenarios are expected to be the first to be implemented? What aspects should be paid attention to in the landing process?. Hebaohong: blockchain originates from digital tokens and is very mature in this field. However, due to its strong regulatory characteristics, it is not suitable for industrial implementation. However, the application of blockchain in other scenarios is still in the exploratory stage worldwide. There are two principles for what scenarios blockchain is suitable for: first, it depends on what scenarios the world is exploring around blockchain; Second, it should be combined with Chengdu's local advantageous industries and fields. At present, the global blockchain application mainly focuses on the digital finance field, such as the connection between industry and finance, clearing and settlement, etc. the financial scenario requires the data to be tamper proof and traceable. Therefore, promoting the implementation of blockchain technology in the financial and other scenarios must be the first.
        Chengdu's science and technology have developed very fast in recent years. In the implementation of blockchain scenarios, we should combine our own advantages, focus on developing blockchain fields that are generally favored, such as supply chain, and choose something that combines with the actual scenarios in Chengdu. But at the same time, we should realize that blockchain is not omnipotent. We must find an application scenario suitable for it. The core value of blockchain is to enable mutual trust when multiple parties participate, such as some scenarios in the field of digital finance &mdash& mdash; The parties involved in the transaction do not trust each other, and some data must not be tampered with secretly. This scenario is particularly suitable for blockchain. In addition, in some scenarios, the goal can be achieved by using centralized databases or traditional databases. However, the use of blockchain will lead to a sharp decline in performance and an increase in cost, which is not very cost-effective. This is what I must emphasize.
        NBD: nationwide, what is the development level of Chengdu's blockchain industry? What development opportunities will the 2020 innovation and Trade Fair bring to Chengdu blockchain enterprises?. Hebaohong: on the whole, Chengdu's blockchain industry is in a state of catching up with the first tier cities. Although there is still a significant gap between Chengdu and Beijing, Shenzhen, Hangzhou and other cities in the formation of blockchain ecology and the exploration of blockchain applications, it has been slowly closing down. Chengdu's blockchain development must highlight its own characteristics and focus on some advantageous fields and scenarios, rather than doing everything. For example, Chengdu's key development areas such as financial technology can highlight local advantages.
        As a part of Chengdu's digital technology development, the 2020 innovation and Trade Fair will better enable other blockchain enterprises in China and the world to further understand Chengdu, understand Chengdu's advantages in policies, talents and environment in the development of blockchain industry, and attract more blockchain enterprises and talents to settle in Chengdu, so as to form a blockchain industrial ecology on a larger scale, This is very helpful to promote the development of Chengdu's local blockchain industry.
