Time : 30/04/2022 Author : m65njd Click : + -
        Blockchain has attracted much attention in recent years due to its characteristics of decentralization, openness and transparency, non tamperability of information and privacy protection, and has become a new hotspot in many fields. However, at the same time, some coins accompanying the emergence of the blockchain have also caused many foam, which has deterred many industries. So, how should the communication industry "open" the blockchain correctly?. On October 24, the Political Bureau of the CPC Central Committee conducted the 18th collective learning on the development status and trend of blockchain technology. When presiding over the study, General Secretary Xi emphasized that the integrated application of blockchain technology plays an important role in new technological innovation and industrial transformation. We should take blockchain as an important breakthrough point for independent innovation of core technologies, clarify the main direction of attack, increase investment, focus on tackling a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation.
        The general secretary's speech pointed out the direction for the development and application of blockchain. As the basic and leading industry of the national economy, how to use and develop the blockchain in the communication industry has also attracted the attention of people in the communication industry. As a national think tank, CCID Research Institute is the first authoritative research institution to track, research and analyze the blockchain. CCID Research Institute also set up a blockchain Research Institute earlier to focus on the research of blockchain technology and application development, and carry out a number of blockchain field evaluations and evaluations. The ranking of global public chain technology evaluation was released for 14 consecutive issues, which attracted wide attention from the industry. To this end, Xin Pengjun, editor in chief of all media of communication industry news, recently talked with Dr. Liu Quan, director of Cyber Security Research Institute of CCID think tank, President of CCID blockchain Research Institute and Secretary General of China electronic certification service industry alliance, about the relationship between blockchain and communication and the application of blockchain in the field of communication industry.
        Xin Pengjun: as a distributed system above communication, the blockchain needs certain computing and communication resources. If the communication resources do not match, the operation efficiency of the blockchain may be affected and restricted. What do you think are the core requirements of blockchain for communication networks?. Liu Quan: blockchain is a distributed ledger Technology (DLT). It is possible to conduct open and trusted exchange on the Internet without using a central server or an independent trusted authority. The demand of blockchain for network communication is mainly reflected in higher transmission speed, higher bandwidth and lower transmission error rate. First, because the blockchain adopts P2P network, each node is decentralized, and the data received by each node is often different during the whole network data broadcast, resulting in low efficiency in the block out verification stage, which is not conducive to the improvement of the performance and efficiency of the blockchain.
        Second, with the popularity of blockchain applications, more and more pictures, multimedia videos and other large storage files need to be uploaded. The low bandwidth will seriously limit the uploading of large-capacity files and the transmission between nodes. Third, because the blockchain is a distributed ledger that cannot be tampered with, it requires that the data be more accurate in the transmission process, and that the channel transmission should have anti-interference and self correction capabilities. In general, blockchain needs faster and more accurate communication network technology. Xin Pengjun: there is demand, there is opportunity. At present, the income of the telecommunications industry is hovering at a low level. What opportunities do you think the development of blockchain will bring to the development of the telecommunications industry?. First, the P2P network structure adopted by the blockchain provides a new network transmission scheme for the communication industry.
        The traditional transmission of information makes it easy for attackers to obtain and intercept information through path information tracking, thus generating the demand and cost of ensuring the security of information transmission paths. The P2P network architecture of the blockchain can fundamentally solve the path tracking problem. In addition, P2P architecture has the advantages of attack resistance, high error tolerance and high scalability, which can improve the resource utilization of idle nodes in the network. Second, the blockchain distributed node computing structure can reduce the ultra-high load of the centralized communication architecture in the era of the Internet of things. The centralized communication network architecture will not be able to support the access of 100 million IOT devices. The introduction of edge computing can relieve the pressure of information processing to a certain extent. However, the blockchain can provide more flexible and independent edge computing nodes, and the security of edge computing nodes can be greatly improved through the functions of data tamperability, authority division, identity authorization and verification.
        Third, blockchain distributed storage can solve the data security problems of traditional communication and telecom operators. Under the traditional telecom operation mode, all user information is stored in the central database of the operator. Theoretically, there may be large-scale information leakage, causing huge losses. Blockchain uses distributed storage and cryptography technology to ensure the security, integrity and privacy of data storage. Fourth, the blockchain can realize cooperation and mutual trust between the upstream and downstream of the communication industry chain. The characteristics of the blockchain, such as decentralization, tamper resistance, multi-party consensus mechanism and multi-party governance, determine that the blockchain has important value in solving the problems that require multi-party joint decision-making and mutual trust in the telecom industry cooperation, optimizing the cooperation and coordination between operators and the upstream and downstream industrial chains.
        Xin Pengjun: as a basic and leading industry of the national economy, the communication industry provides the information network foundation for the economy and society. Information and communication technology has also become an enabler and accelerator for the digital transformation of various industries. But at the same time, the communication network itself also faces many challenges and changes in management, security and energy consumption. What applications do you think blockchain can bring to the communication industry to help the communication network to be efficient, simple and safe?. Secure communication with distributed encryption. Traditional VoIP (voice transmission based on IP) communication platform relies on session boundary controller (SBC) and VoIP hardware to maintain security. However, SBC is a centralized server storage and verification mechanism, which implies some serious security vulnerabilities. Once the central server is broken, the consequences are unimaginable.
        Distributed security verification based on blockchain technology cannot be deleted or tampered with. Advanced encryption technology can be used to ensure data security in the process of transmission, verification and sending data. In addition, the blockchain can also improve the identity verification mechanism of VoIP, and realize identity identification and authority management by distributing and saving telephone identity tags. Telecommunication equipment management. At present, due to the large number, variety, manufacturers and batches of telecommunication equipment, it is difficult to form transparent and penetrating management from top to bottom. The whole process technologies such as automatic collection, trusted storage, record traceability and intelligent analysis of patrol inspection data are still incomplete. The underlying data storage based on the blockchain, combined with technologies such as the Internet of things and artificial intelligence, provides operators with equipment inspection and equipment life cycle management services to improve the inspection quality and efficiency.
        The blockchain technology is used to build an alliance chain integrating group companies, operators, equipment manufacturers and manufacturers at all levels, to monitor equipment data in real time, obtain reliable data on the chain, and check the implementation of equipment inspection in real time. The equipment management platform interacts with the operator's business system through the interface, synchronizes equipment fault information and equipment risk information in real time, predicts faults in advance and handles them in time. Dynamic spectrum management and sharing. At present, the "static management strategy" is adopted for wireless spectrum. The spectrum is not only seriously short, but also the utilization rate of authorized spectrum is low. Dynamic spectrum sharing has significant advantages, but there are some problems such as resource sharing trust and spectrum value transfer.
        On the premise of clarifying the relevant laws, regulations and application scope, dynamic spectrum sharing can be realized based on the blockchain technology. Each spectrum owner can act as a blockchain node to dynamically share its own authorized frequency band through the blockchain. The on chain contract combines the use characteristics of spectrum owners to develop a dynamic spectrum sharing mechanism, and conduct settlement and billing according to the provisions. Terminal equipment safety protection. A large number of communication terminal equipment are exposed in public areas, which greatly increases the risk of network attacks, including data pollution and malicious terminal access. The blockchain can ensure the terminal security of the entire communication system through strict identity verification mechanism and data encryption mechanism. Each terminal device will have its own public and private key pair. The blockchain system maintains a list of terminal identities through smart contracts, and reviews whether the device has the right to access nodes and upload data, thus avoiding malicious access and data pollution.
        In addition, the data of each terminal will be encrypted to ensure that there will be no data leakage during data transmission. Xin Pengjun: 5g is coming. At present, the three major operators have also officially announced the commercial use of 5g. However, globally, 5g innovative businesses are still in the process of being nurtured. The industry expects more innovation from 0 to 1 in 5g businesses. As two innovative technologies, what chemical reactions can 5g and blockchain stack produce and what applications can be innovated. Liu Quan: both blockchain and 5g are new technologies. The great potential and value of the combination of the two have become increasingly prominent. As a communication infrastructure, 5g provides the possibility for the transmission of huge data and information, and provides a more efficient and reliable transmission speed.
        As a decentralized and privacy protection technology tool, blockchain helps 5g solve reliability, security, privacy, trust and other issues, improve network information security and service efficiency, and innovate business models. Smart city field: the integration of blockchain and 5g technology, the tamper proof characteristics of blockchain ensure the security of transmission data, simplify the government process through distributed network structure and smart contract, 5g can greatly improve the ability and efficiency of data exchange and mutual trust, and multi-dimensional and high-precision big data will provide more flexible and rich experience for government services. For example, government affairs remote examination and approval, remote hearings, public welfare and charity, citizens' elections, and citizens' credit.
        Tax departments and industrial and commercial administration departments can use 5g and blockchain technology to upload bills and registration information in real time to avoid fraud. In addition, 5g combined with Internet of things technology can achieve efficient collection of food and drug throughout the production cycle, and improve the authenticity of data on the blockchain. In the future, smart city information will be presented in video or Ar / VR images. 5g technology provides efficient and fast transmission for large-capacity information transmission. Blockchain technology can provide functions such as identity identification, card storage and tracing. In the field of Intelligent Manufacturing: 5g has the characteristics of low delay, high reliability and massive connection, which can reduce the transmission delay of production data to more than milliseconds.
        Blockchain technology can solve the problems of industrial equipment registration management, access control, monitoring status, data trusted transmission, controllable management of industrial Internet platform, production quality traceability, etc., ensure the safety and efficiency of intelligent manufacturing, and promote the transformation and upgrading of manufacturing industry. The integration of 5g and blockchain will provide more real-time, accurate and secure data transmission and storage for intelligent manufacturing, and further promote the development of intelligent manufacturing, marginalization and customization. Product traceability: 5g provides fast and efficient transmission guarantee for the traceability information of products such as pictures and videos. Taking agricultural products as an example, the traceability monitoring node can completely cover the growth process, drug use, or cultivation process, fertilizer use method, illumination and other information of the products. At the same time, it can collect the data of various key nodes such as product packaging, circulation and consumption, and be recorded in real time and completely through the characteristics of 5g high bandwidth and multi connection.
        Upload data to the blockchain through 5g efficient data collection mode, and provide consumers or third-party systems with complete, authentic and tamper proof traceability data services. 5g can ensure the integrity, comprehensiveness and speed of traceability data transmission, and blockchain can ensure the reliability of traceability data. The integration of 5g and blockchain technology will promote the rapid development of traceability industry. In the field of vehicle Networking: with the ability of 5g with low delay, high reliability and massive connection, networked vehicles can not only help realize real-time communication of location, speed, driving direction and driving intention between vehicles, but also can use roadside facilities to assist networked vehicles to perceive the environment.
        The blockchain can solve the problem of system security risks, and introduce vehicles, people, service providers and manufacturers into the chain. Through its tamper proof characteristics, it ensures the security of data information. Users in the chain can share the data information protected by the blockchain, thus improving the safety of driving and the efficiency of service provider management. In the field of Finance and insurance: 5g terminal equipment provides strong technical support for the insurance industry's investigation and loss determination. The terminal equipment is equipped with 5g high-definition image transmission and machine vision intelligent analysis functions. Combined with the blockchain technology, the data can be reliably transmitted in real time in the 5g network environment to help realize the trusted interaction of intelligent terminals.
        In addition, the traceability of blockchain technology makes the insurance business process more transparent, which is conducive to enhancing mutual trust between insurance companies and customers. Xin Pengjun: thank President Liu Quan for accepting the interview. The general secretary stressed the need to build a blockchain industrial ecology, accelerate the deep integration of blockchain and cutting-edge information technologies such as artificial intelligence, big data and Internet of things, promote integrated innovation and integrated application, and also pointed out the need to promote the integration of blockchain underlying technology services and new smart city construction, explore the promotion and application of information infrastructure and other fields, and improve the intelligent and accurate level of urban management. As a representative of the integration of advanced information technology, the communication industry is naturally coupled with the blockchain.
        It is believed that the two-way enabling and integrated application of information communication and blockchain will promote the healthy and orderly development of blockchain and also bring new opportunities to the communication industry.
