Before the official introduction of the six-domain chain, it is better to simply understand what the "six domains" are. The sixth domain is the abbreviation of the six-domain model of the Internet of Things. It is a six-domain model led by China, based on the socialization of the Internet of Things. After voting by 33 member states, it has become the world's first international standard project for the top layer architecture of the Internet of Things. IEC 30141. If an Internet of Things project is a house, then the six-domain model is the basic structure of the house, or rather, the beam and pillar of the house.
What is the six domain chain? Simply put, the six-domain chain is a blockchain underlying public chain that serves the Internet of Things. Specifically, the Six Domain Chain (SDChain) is the world's first decentralized public blockchain ecosystem that incorporates the "6-domain model" international, national standards, and distributed blockchain reference architecture standards for the Internet of Things.
For a more convenient understanding of the six-domain chain, we may wish to ignore some of the above introductions, leaving only two core concepts: the Internet of Things + blockchain. What we need to discuss at this point is how is the Internet of Things linked to the blockchain?
Just like the firm belief that the blockchain will have a significant impact on the world, we have never doubted the ability of the Internet of Things to reshape this world. According to the Ministry of Industry and Information Technology, the scale of China's Internet of Things industry in 2009 was 170 billion yuan. By 2015, this figure had risen to 750 billion yuan. By 2020, the overall size of China's Internet of Things is estimated to exceed RMB 1.8 trillion. These data clearly show that the Internet of Things is showing strong growth momentum under the trend of the Internet of Everything.
Under the trend of material information and value digitization, the Internet of Things (IoT), as the main medium for extensively connecting the physical world and the digital world in the wave of the transition from the atomic world to the digital world, undoubtedly holds the epoch-making significance of establishing a smart world. The historical mission of the goal. However, there are still many problems in the Internet of Things industry at present, and the conditions for development are greatly constrained. For example, the Internet of Things has high cost, difficulty, security, and privacy issues in practical applications. At the same time, the integration of the Internet of Things and traditional industries also lacks a unified framework and an effective network credit guarantee system.
How can traditional industries connect to the Internet of Things as easily as the Internet? How to ensure the legal identity of IoT devices, data validity, and the authenticity, consistency, and inability of data to be transferred in different systems?
For the Internet of Things to be really high-speed development, we must first solve these problems. The answer given by the six-domain chain is that the breakthrough to solve these problems is the full integration of the Internet of Things system and the distributed ecosystem of the blockchain. Simply put, that is the development of the Internet of Things can not do without the help of the blockchain, in a nutshell, blockchain is the body, the Internet of things is used.
What the six domain chains need to do is to integrate the Internet of Things and the blockchain to form a decentralized public blockchain ecosystem, so that all industries can build on their own needs, efficiently and cost-effectively. DApp based on a six-domain model reference architecture.
How is the six domain chain concrete? This should be divided into two aspects.
On the one hand, in the current stage, most of the Internet of Things applications are still closed-loop applications in specific areas, and it is impossible to establish closed-loop business; cross-domain cross-industry interoperability sharing and application collaboration is obviously insufficient, and it is unable to compensate for the defects of the business loop in the industry. Based on the “six-domain model†IoT architecture standards can effectively guide and establish an IoT operation service system to ensure the actual and effective operation of the system, sustainability, and business closed-loop.
The “6-domain model†reference architecture of the Internet of Things has systematically combed the complex IoT industry application related elements and analyzed them from different perspectives. The application-level business functions are divided into major principles and six major domains are set:
Internet of Things User Domain (Define Users and Requirements)
Target object domain (explicit "object" and associated attributes)
Perceptual control domain (sets the desired perception and control scheme, ie, the association of "objects")
Service Providing Domain (processes raw or semi-finished product data into corresponding user services)
Operation and maintenance management domain (safety, reliability, stability and precise operation of the system at both technical and institutional levels)
Resource Exchange Domain (Implementing the sharing and exchange of information and market resources between a single IoT application system and external systems, establishing a closed-loop business model for IoT)
Between the domain and the domain, network connections are established according to business logic to form a single IoT industry ecosystem. A single IoT industry ecosystem then forms a cross-industry cross-sectoral synergy system through its own resource exchange domains. To sum up, the six-domain model has improved the collaboration system between the six domains, clarified the framework of the convergence of the Internet of Things and traditional industries, and reduced the difficulty of integrating the Internet of Things into traditional industries.
On the other hand, although the six-domain model solves the ecological system problems in the single IoT industry and the cross-industry cross-domain coordination problem, it still lacks an effective safeguard mechanism in the credit system and value system. , it happens to be the blockchain can provide.
Blockchains have unique technical features that can effectively address issues such as big data management, trust, security, and privacy that face the development of the Internet of Things, and thus advance the development of the Internet of Things into a distributed, intelligent advanced form. The blockchain can provide trust, ownership records, transparency and communication support for the IoT, implement scalable device coordination forms, build efficient, trusted, secure distributed IoT networks, and deploy massive amounts of device network operations. Data-intensive applications, while providing effective protection for user privacy.
Blockchain is a universal underlying technology in the Internet of Things and can provide a high-capacity, trustworthy infrastructure for large-scale IoT networks. The application of blockchain to the Internet of Things (IoT), such as industrial production, can reduce the operation and credit costs of centralized equipment networks and improve operational efficiency and utilization of industrial assets. At the same time, the blockchain can also guarantee the security and privacy of the Internet of Things from storage, information transfer and other technologies through authentication and authorization mechanisms. In addition, the blockchain can bring about the expansion of the intelligent application model of the Internet of Things and promote business model innovation.
As a decentralized underlying ecological operation platform, blockchain can fully protect the Internet of Things's credit system and value system.
The core business of the six domain chain mainly includes:
1. Based on the application needs of specific industries, based on the six-domain model reference framework of the Internet of Things, we will promote the establishment of DApps for different industries, such as agricultural internet of things, industrial internet of things, and energy internet of things, to provide digital assets for each DApp, as well as for In the six domains, various types of user entities in the six domains provide digital credit identity registration, management, data linking, data validation, data query, smart contract setting, smart contract triggering, automatic splitting, and other services. To ensure the consistency, authenticity, and irreversible modification of data, ACM, an asymmetric credit mechanism between people and things, is established to ensure the security, efficiency, and value interconnection of data assets.
2. Quota distribution of six domain chain digital asset tokens - SDA for digital asset circulation transactions, accounting consumption and consensus rewards, and application of eco-incubation, community building, commercial cooperation, and marketing promotion. With the continuous prosperity of the six-domain chain business ecosystem, coins, chains, and industrial Internet of things are symbiotic and prosperous with each other, and their respective values ​​and benefits have been continuously improved.
3. Based on a large number of block-based encrypted data resources in the six-domain chain, establish a win-win cooperation, continue to tap potential value, incubate innovative applications, drive innovation in IoT technology and artificial intelligence, innovation in IoT financial services, and trace the source of supply chain Efficient and collaborative development of service innovation, market service innovation, etc.
The infinite delusion of the six domain chain: When the Internet of Things encounters the blockchain Internet of Things as the main medium for extensive connection between the physical world and the virtual world, on the one hand, it establishes interconnection and efficient coordination mechanisms between different types of users and objects in the physical world. Various industries continue to improve efficiency and efficiency, and promote a new "wisdom revolution."
For example, we can place some sensors at key points on the traffic road instead of setting up traffic police to monitor the operation of urban traffic. In the event of a congestion event, these IoT sensors can instantly send data messages to navigation software to notify users to avoid congestion points. In this way, people can use the Internet of Things to achieve more efficient transportation.
On the other hand, the tens of billions of potential terminal terminals of the Internet of Things and the high concurrency of transactions can continuously create enormous, high-value data assets for people. However, without the help of blockchain, that is, the data asset value system and network credit system have not been established, such high-value data asset resources will be difficult to achieve free flow and cannot be used on a large scale. This is also an important issue that restricts the development of the Internet of Things industry.
In this regard, Dr. Shen Jie, an authoritative international expert on the Internet of Things and the “six-domain model†proposed by the Internet of Things, believes that blockchain intervention can transform the business model of the Internet of Things industry. He uses the current fishery Internet of Things as an example.
“It used to be very simple to sell sensors to farmers or to collect service fees. This is actually stopped at a relatively low level - the user of this sensor is considered to be farmers only, and giving all the costs to farmers often leads to Farmers can't accept what is overlooked, something that can be obtained through this sensor, these data banks also need, insurance companies need, consumers also need, so that the value of the data generated will dilute the cost and subvert the tradition Business model: The Internet of Things system can help these data to be continuously digested, absorbed, and processed into valuable products. At this time, the cost of building the Internet of Things is greatly reduced, and the space and value of benefits are getting bigger and bigger.
It is not difficult to imagine that the Internet of Things has not only further freed people's hands, but has also led people to separate themselves from occupations where the workload is heavy, the content of jobs and work modes are fixed, and high-value data resources can be generated at all times. With the intervention of blockchains, resources can be fully realized in efficient and free flow, creating revenue and value for sensor users and lowering the cost of establishing the Internet of Things. The cost reduction will greatly promote the rapid development of the entire Internet of Things, making the Internet of Things accelerated. The combination of the Internet of Things and blockchain can achieve the common prosperity of the physics and digital ecology, and establish a new all-in-one infrastructure.
