Block chain security consulting firm warp future , he said: famous contemporary thinker, Foundation on Economic Trends in Washington, DC, the main Jeremy Rifkin in his book "zero cost society" introduced, with microelectronics, new materials, 3D printing With the continuous development and application of new technologies such as, electric energy storage, the Internet of Things has moved from behind the scenes to the front, billions of people and millions of organizations are connected to the Internet of Things, so that humans can share in a global collaboration in a way that was unimaginable before. Share its information, entertainment, energy, products and other economic life.
The era of the Internet of Things has come, and collaborative sharing will bring a subversive change to the economic model that dominates the development of human production, and mankind will enter a new and more advanced social form.
The development status and bottleneck constraints of the Internet of Things
As the third industrial revolution and the new direction of the future development of social interconnection technology, the Internet of Things has brought tremendous changes to people's production and life. At present, the Internet of Things technology is gradually becoming an important force to promote the innovative development of various industries. Related research and research predict that the compound growth rate of the Internet of Things industry from 2019 to 2022 will be about 9%; it is estimated that by 2022, the scale of China's Internet of Things industry will exceed 2 trillion yuan; it is estimated that by 2022, the scale of China's Internet of Things connection will reach 7 billion. For the foreseeable future, the Internet of Things will replace the mobile Internet and become the main driver of the information industry.
However, the large-scale application of the Internet of Things has also produced some problems. For example, a large number of IoT devices are directly exposed to the Internet, lack of effective security protection mechanisms, and there are risks of user privacy leakage and system security risks. Such security issues have become one of the major threats faced in the development of IoT technology.
Although the development of cryptography and distributed data management technology in recent years has improved the security of the Internet of Things system, but limited by the complex and dynamic topology of the Internet of Things and the limitations of equipment hardware resources, traditional security technologies are in meeting the security requirements of the Internet of Things. There are still many shortcomings. The security threats of the Internet of Things such as data leakage, hacker intrusion, and communication interference reported from time to time in the real society are worrying.
Blockchain technology empowers the safe operation of the Internet of Things
Blockchain has the characteristics of natural distributed storage, consensus mechanism, encryption algorithm, etc. These characteristics endow the Internet of Things with the characteristics of traceability, non-tampering, and autonomy. It has unique advantages in solving the bottleneck problem of the Internet of Things, which greatly improves The security index of the Internet of Things.
We know that blockchain is a distributed database that is recorded and maintained by multiple parties. By combining hash function operations, blockchain data presents a chain structure that is strictly ordered. This technical feature determines that the data in it cannot be tampered with or forged by any node, so it has irreplaceable advantages in data integrity verification, data traceability, multi-party trust establishment, and cooperative sharing relationship establishment.
In the development of the Internet of Things, it is now mainly based on cloud-side collaborative operation. A large amount of data generated during the operation of the Internet of Things is uploaded to the cloud for processing, which will cause huge pressure on the cloud. In order to share the pressure of the central cloud node, the edge computing node can be responsible for data calculation and storage within its own scope.
The design of full nodes and lightweight nodes in the blockchain network is in line with the development trend of the existing cloud-side collaborative IoT system, because full nodes are mainly responsible for the addition and synchronization of blocks, and lightweight nodes are not synchronized with the chain. All the data on the above, mainly through the form of access authorization, obtain part of the core data on the chain, which coincides with the needs of the Internet of Things.
In terms of system architecture, the blockchain adopts a five-layer architecture that is divided into data layer, network layer, consensus layer, incentive layer, and smart contract layer from top to bottom, and each layer is responsible for its own functions. For example, the network layer will store all transaction records, the consensus layer will deal with risks such as the Byzantine generals problem and the double spending problem, the incentive layer will encourage more IoT users to participate in on-chain maintenance in some ways, and the application layer will provide users with specific Serve and solve corresponding needs. All these provide strong technical support and service guarantee for the Internet of Things.
Blockchain, as a decentralized technology, builds powerful security and trust empowerment for the Internet of Things. It can be said that the combination of the two is a historical necessity and a match made in heaven. The Internet of Things is a real-world application of blockchain connection, and the blockchain provides data security and privacy protection for the Internet of Things.
For example, blockchain can provide a mutually trusted data interaction platform for different manufacturers and devices, and achieve cross-border purposes by solving interoperability and interconnection problems. At the same time, the consensus mechanism of the blockchain can realize functions such as traceability, confirmation and integrity verification of data assets. The data privacy protection and security mechanism it introduces greatly enhances the value of data asset sharing, openness and application of the Internet of Things.
Internet of Things + Blockchain Technology Application
Blockchain technology originated from Satoshi Nakamoto's Bitcoin platform, which originally belonged to the field of cryptocurrency. But with the continuous development of technology, the world has discovered more and more huge advantages of blockchain. The gradual maturity of its own smart contracts and cryptography technology has allowed blockchain to show great commercial value in food traceability, tracking and tracing, resource sharing, privacy and security, etc., and it is playing more and more in this IoT era. Big energy.
For example, the food safety and quality problems we experienced such as Sudanese red duck eggs, clenbuterol, and poisoned bean sprouts still occur from time to time, and some problems even recur, which greatly test the credibility of the government. In May 2020, another "big head doll" incident occurred in Chenzhou, Hunan. After investigation, the Yongxing Aiyingfang Maternal and Child Store was suspected of using protein solid beverages to pretend to be infant milk powder for sales to deceive consumers, resulting in varying degrees of malnutrition, low weight, short height, and insufficient vitamin D3 intake for the children involved. Wait for the situation. In reviewing the entire incident, we see that the current food traceability market still has many shortcomings and weaknesses. If a reliable and widely used food traceability system can be established to effectively supervise the quality and safety of food and dairy products, As a result, the transmission of information between producers, operators and consumers will be faster and more efficient, which will greatly reduce the occurrence of such incidents, and will also facilitate better supervision by relevant government functional departments.
The blessing of blockchain technology is expected to break the burden of the traditional food traceability system and reshape a new traceability system with information circulation and tamper-proof. Through the Internet of Things, the blockchain can integrate and record product production and processing information, warehousing logistics information, and transaction information in the network. Through traceability, the information is connected in series and displayed to consumers, so that consumers can clearly see the flow of each product. , To ensure the authenticity of the source information and the tamper-proof of the recorded information, help the supervisory department improve work efficiency, and make the tracking and determination of food quality issues more efficient.
In this regard, Wanglian Technology has made an active layout. Through the use of many experiences in the blockchain field, it helps the food industry to speed up the construction of a blockchain traceability system. Through transaction data, sales data, passenger flow data, and vegetable price data in the market , Merchant data, activity data collection, storage and query, improve the efficiency of merchant docking, realize the reverse traceability of consumers' purchase of products, so that the food industry will no longer fear the intrusion of force majeure.
Looking to the future, with the accelerated development of big data, cloud computing, and smart engineering, the Internet of Things is entering a rapid development channel and will become a major strategy for major countries in the world to seize the commanding heights of a new round of economic and technological development. With the help of the decentralization, digitization, interconnection, traceability and other characteristics of the blockchain, a data sharing platform will be built between manufacturers, brands, consumers, regulators, retailers and other individuals, and a value transmission agreement will be built to realize inter-individual Point-to-point value transfer, mapping real-world assets into digital assets, realizing the interconnection of all things, and tracing individual "past and present", fits many application scenarios, and plugs wings for the Internet of Things.
