Blockchain +5G: Communication is easy to build, security is difficult to solve

Information transmission is an important carrier of social life. From ancient rumors, beacon towers, flying pigeons to the era of global information in the 21st century, the way of information transmission and the speed of transmission have achieved a qualitative leap. With the birth of high-tech such as blockchain and 5G, there will be new changes in the information industry.

On June 6, the Ministry of Industry and Information Technology issued 5G commercial licenses to China Telecom, China Mobile, China Unicom and China Radio and Television. The 5G commercial curtain of China, which has been brewing for many years, was officially opened.

In the 5G era, how should the blockchain identify the market position? How can the combination of blockchain technology and 5G be applied to specific business scenarios?

On June 19th, at the 24th sharing session of “Zinc”, the founder of Zinc Link, Gong Haijun invited Peng Bo, founder and chairman of Shenzhen Core Chain Technology Co., Ltd., to be “a region under strong communication”. The blockchain breaks the theme to answer the above questions.

Zinc Link: What are the difficulties of 5G to achieve large-scale landing? What is the market positioning of blockchain technology in the 5G era?

Peng Bo: 5G commercial is accelerating. As a complex and highly innovative communication system, it will take a long time for the 5G product business maturity to satisfy users.

Large-scale construction requires huge capital investment, and coverage and other issues will also limit the exploration of various application scenarios. Among them, the biggest difficulty lies in finding 5G high-value service explosion points.

Currently familiar 5G scenes, such as smart city, auto driving, car networking, smart home, VR, AR and so on. In the case of the existing 4G system support, although various types of business have already developed very much, the related killer-level high-value applications still lack sufficient influence. In the early stage of network deployment, 5G lacked strong business guidance to promote and improve the industrial ecology.

As we all know, the supporting technology at the bottom of the blockchain is communication and security. If these two technologies enter the bottleneck period, it will restrict the development of the blockchain-related business scenarios. Especially for communication technology, different landing scenarios have different requirements for supporting communication technologies.

The blockchain is based on the decentralized network characteristics of the nodes, which further emphasizes the communication support requirements on the node side. The 5G commercialization process is also a process in which business scenarios are constantly presented. In this process, the core positioning of the blockchain is the enabler and accelerator of the business scenario.

Zinc Link: What changes will 5G bring to the blockchain industry? Where is the strong demand between the two?

Peng Bo: The changes that 5G brings to the blockchain industry are mainly divided into two aspects.

On the one hand, 5G provides a more cost-effective communication service that will greatly reduce the access and operating costs of blockchain nodes. The blockchain is a node-based decentralized network. Compared with the traditional centralized network, the node chain needs to perform more quality data interaction between nodes and nodes. The node services of many blockchains cannot form effective commercial services because the nodes themselves cannot obtain a high-quality and low-cost communication guarantee. This situation severely restricts the large-scale application of the blockchain.

On the other hand, 5G supports the communication requirements defined by specific application scenarios, which can efficiently support the individualized needs of various node services in the blockchain. The interaction of different blockchain communities, the interaction of different application scenarios in the blockchain community, and the different needs of services in different scenarios, forming a diverse service demand. The effective support of 5G will effectively promote the application of various blockchain application scenarios and truly serve the individualized needs of different users.

In this case, the access and operation cost of the blockchain node is greatly reduced, which can effectively promote the landing of the blockchain in the application scenario. At present, the application of many blockchains is difficult. One factor is its own business model. In addition, many community applications are costly and the user experience is very poor, which seriously restricts the development of the application itself.

After all, for real users, the application itself is the core element of the experience. Whether the application is based on blockchain, 5G or other black technology is just a technical choice path. The effective support of 5G at the bottom of the communication will accelerate the improvement of the user experience.

With the development of 5G, businesses with high interactivity and real-time bandwidth requirements such as VR/AR, games, and car networking will also generate many business models centered around users. In this case, the blockchain's inherently all-encompassing support for community operations will also provide more business model choices for these services.

Zinc Link: What do you think is the difficulty of implementing blockchain combined with 5G in specific scenarios? What are the advantages and disadvantages of cross-scene applications?

Peng Bo: The nature of the blockchain is an empowerment tool. It is a production relationship tool. It is a 0 behind, which means that any blockchain project needs to have a strong industry base. The 1 in front of 0 must stand. From this perspective, the difficulty of landing 5G blockchain application is that the application of 5G itself is not mature enough. Synchronizing the application of blockchain empowerment is even more difficult.

In the 4G era, the most mature application of the blockchain is in the financial sector. For example, cross-border payments, smart block-based blockchain financing services, thanks to the maturity of traditional Internet finance. While 5G is optimistic about VR/AR, its own gameplay is still pondering. The blockchain-based gameplay needs to be pondered, and large-scale commercialization takes more time.

The area in which blockchains are inherently good at cross-scenario applications. From a technical perspective, decentralization allows for differentiation of individual nodes. The inherent advantage of the blockchain is that it can flexibly and conveniently coordinate the needs of different scenarios based on various types of certificates.

Moreover, differently differentiated scenarios can form different blockchain communities and then deliver communities through various cross-chain technologies. However, the application of 5G scenes is not particularly mature. The focus of the industry is currently focused on solving the business problems that need to be solved within each scenario.

In this case, in the cross-scenario application, 5G requires more operational and resource integration capabilities than the traditional project landing form through the blockchain landing. After all, compared to the 5G scene application, the application maturity of various 4G-based scenarios is much higher.

Zinc Link: How to understand the 5G+ smart parking lot in Huangpu District of Guangzhou? Is there any possibility of landing in other subdivisions? why?

Peng Bo: The 5G blockchain smart parking lot in Huangpu District is a very interesting and valuable business attempt. From the public channel information, the number of parking lots currently involved is only four, no matter whether the value attribute of 5G or the value attribute of the blockchain is not obvious.

Based on the 4G non-blockchain, this scenario can also be done in place. So based on the blockchain, what is the specific difference in terms of the actual user experience? Based on 5G, what additional services can I provide? This requires more exploration and business trial and error to find the point of integration after 5G and blockchain fusion. This project is a very good start, but now it is just the beginning.

The integration of 5G and blockchain, I am particularly optimistic about several areas: in the interactive scene of VR, AR, there are many opportunities in the application field of Internet of Things and smart home. The combination of VR/AR, especially with games, is itself based on the user's highly interactive nature. The blockchain integrates high-efficiency business models of users, from content integration to investment and financing, and is very powerful for commercial promotion of such scenarios.

In addition, the Internet of Things and smart homes require a huge amount of data to function. Not only is the amount of data large, but the data needs to be used effectively, and high-quality data in various fields and angles is needed. This kind of data, the traditional centralized centralized method, is extremely costly. The blockchain is a data-based production relationship tool. The more data is aggregated and the more interactive the data nodes are, the more effective the blockchain application is, and the different incentive forms can be provided according to the needs of the scene. Coordinate different data providers to form a synergy.

Zinc Link: In the future, what new challenges will 5G bring to blockchain technology?

Peng Bo: The future 5G brings more challenges to the blockchain than opportunities. From a challenge point of view, perhaps because of the acceleration of 5G's application of blockchain, the security problems caused will really restrict the expansion of effective users in the blockchain community.

After all, the underlying technology of the blockchain supports communication and security. Now that the communication leg is completed, the problem of safe lameness becomes more serious. After many applications come up, massive amounts of data are aggregated, and there is a demand for a large amount of data. The problem is that the data itself is not accurate enough, safe, the application is not secure enough, and how to protect the user's rights.

The application of the existing blockchain in finance, due to security pressures, the real ordinary users have not become the main force of various financial applications in the blockchain. The current main force is the learning-type high-risk preference. Users with poor learning ability or weak risk control ability have become the leeks for all kinds of financial projects, and the appropriate "IQ tax" payers. However, large-scale applications, even for financial applications, require ordinary bank users who are ordinary people, and traditional fund users can also get reliable services. Without a systematic, highly functional, high-security mechanism from the user's point of view, it is difficult for ordinary users to establish recognition of blockchain applications.
