Market scale of blockchain
Original title: China's blockchain instry market status and development trend analysis in 2019, widely used to accelerate the construction of Digital China. Basically, a relatively mature instrial chain has been formed. With the promotion of national policies and the increasing demand of downstream application fields, the market scale of China's blockchain instry is constantly developing, the regional concentration is high, and the instrial cluster effect is obvious. With the increasing maturity of blockchain technology, the blockchain instry is entering the 3.0 stage as a whole. It has a good performance in finance, logistics, right protection and other fields, and has made great contributions to promoting China's digital construction and accelerating the process of Digital China
instrial chain analysis of blockchain instry: there are many downstream application fields with huge development potential
from the perspective of instrial chain, China's blockchain instry includes upstream hardware, technology and infrastructure; Midstream blockchain application and technical services
application fields of downstream blockchain. The upstream hardware, technology and infrastructure mainly provide the necessary hardware, technology and infrastructure support for blockchain application. The hardware equipment includes mining machinery, ore pool, chip manufacturer, etc; General technologies include distributed storage, decentralized transaction, data service, distributed computing and other related technologies
the downstream application fields include the combination of application blockchain technology and existing instries, mainly including financial instry, logistics instry, right protection, medical health, instrial energy and many other fields. As an emerging technology, blockchain has many downstream application fields and great development potential
the application and service of midstream blockchain includes the construction of infrastructure platform and the provision of technical service support. The construction of infrastructure platform is divided into general infrastructure chain and vertical domain infrastructure chain; Technical service support includes technical support and service support. Similar to upstream technology, technical support is responsible for providing buyers with a series of technical support based on blockchain procts, such as blockchain security protection; Service support includes a series of services such as digital asset trading place, digital asset storage, media community, etc
instry chain analysis of blockchain instry Most of 360 and other enterprises use their own financial companies to apply blockchain technology to launch a new mode of blockchain + finance and broaden the application scenarios of blockchain technology
With the continuous development of China's blockchain technology and the continuous expansion of blockchain application fields, China's blockchain instry will become the forefront of global technology development and open up a new international competition track in the future2. Blockchain has become a new hot spot for innovation and entrepreneurship, and technology integration will expand new application space
3. Blockchain will be widely implemented in the real economy in the next three years and become an important support for the construction of Digital China
4. Blockchain creates a new platform economy and opens a new era of sharing economy
5. Blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy
The blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidatedAnalysis on the expenditure scale and application prospect of China's blockchain instry in 2018 will be close to US $300 million in 2019, so as to solve the short board problem and promote economic development
blockchain technology is expected to be widely used in the economic field
blockchain technology has strong practical significance for cultivating new momentum of economic growth, building an honest society, improving the level of management technology and alleviating the financing difficulties of small and medium-sized enterprises, It is expected to be widely used in the economic field. At present, the application of blockchain technology is still in the early stage of development, facing many challenges. We should actively promote the application of blockchain in many economic and social fields, scenes and environments, create a good environment for instrial development, improve the quality of development, strengthen the research and development of blockchain core technology, professional application demonstration, and strengthen standard manufacturing Personnel training and the construction of public service platform
in 2019, the expenditure scale of China's blockchain market will be close to US $300 million
according to the statistical data of in depth analysis report on business model innovation and investment opportunities of China's blockchain instry published by prospective instry research institute , as of 2017, the expenditure scale of China's blockchain market is only US $83 million. In 2018, the expenditure scale of China's blockchain market will reach US $160 million. It is predicted that the expenditure scale of China's blockchain market will be close to US $300 million in 2019. At this stage, the overall market scale of blockchain is small, because most blockchain projects in the market are in the trial stage, with little investment. On the other hand, many enterprises have realized the potential of blockchain and plan to increase the budget in the future. Affected by this, China's blockchain market will usher in rapid growth. It is estimated that the market expenditure will reach US $1.95 billion by 2023, and the average annual compound growth rate will be 60.51% from 2019 to 2023
Statistics and forecast of China's blockchain market expenditure scale from 2017 to 2023. At present, blockchain technology is not mature in system stability, application security, business model, etc., which can not meet the requirements of "high efficiency and low energy", "decentralization" and "security" at the same time. First, performance. The transaction throughput that can be carried out on the blockchain is not high, and the current block capacity is very small, which leads to network congestion, and it is difficult to meet the needs of high-frequency business. Many projects are also starting to optimize, but there is still a certain distance from the transaction throughput of real scenes such as banks and stock exchanges. Second, consensus mechanism. In terms of energy consumption, consensus algorithms such as workload proof consume a lot of energy and cost, which makes blockchain waste a lot of network computing power and pairing power; In terms of types, there are too few types of blockchain consensus mechanisms at present. In the future diversified business scenarios, more abundant consensus mechanisms are necessary to adapt. Third, security. Privacy protection, harmful information on the chain, smart contract vulnerability, consensus mechanism and private key protection, computing power attack, cryptography algorithm security and other issues make the blockchain face a severe situation of platform security and application security. Fourth, the database problem. Different from traditional databases, blockchain applications require a lot of write operations, hash calculation and verification operations. The database system for blockchain is still a difficult point to break through2. Unclear application scenarios
currently, the blockchain project is still in the exploration stage, and no specific landing scenarios can be found. At present, the more promising fields are finance, sharing economy, Internet of things, public services, etc., but from the perspective of the existing blockchain technology maturity, there are still many problems in the application of blockchain, and there is still a gap from the actual use. First, the immaturity of blockchain technology restricts the implementation of commercial applications. At present, although there are many kinds of blockchain core technologies such as privacy protection algorithm and consensus mechanism, they generally do not have commercial availability. Second, the application mode of blockchain is still in exploration, and the "irreplaceable" advantage of blockchain has not been reflected. Blockchain itself represents a consensus system, so we should build a consensus system in line with the corresponding business scenarios from a higher level, rather than just "business + blockchain". There are many users in China, and the business scenario is complex. Moreover, any commercial proct will involve a very large flow and population. The current blockchain technology can not meet the demand
3, lack of professional talents
blockchain technology is a multi-disciplinary and interdisciplinary technology, which mainly involves operating system, network communication, cryptography, mathematics, finance, proction and so on. However, at present, there are still deficiencies in interdisciplinary and fields in China, and the supply of talents in related fields is seriously insufficient. On the one hand, there is a large gap of R & D technical talents. Blockchain technology research and development mainly focuses on go, JavaScript, C and C + programming languages, and new smart contracts use Haskell, Ocaml, rhoang and other new functional programming languages. In China's talent market, there is a big gap for technical talents with senior R & D experience in relevant languages. On the other hand, there is a lack of bottom design talents. Different from R & D technical talents, blockchain bottom system architecture designers need to master a number of interdisciplinary professional skills, not only to deeply understand the block chain bottom design principle, but also to have the system architecture design experience, but also to master the business logic of specific application scenarios. Although some colleges and universities have launched interdisciplinary ecation and blockchain special skills discipline setting, professional talents are still very scarce
analysis of favorable factors for the development of China's blockchain. In January 2017, the Ministry of instry and information technology issued the development plan of software and information technology service instry (2016-2020), which proposed that the innovation in blockchain and other fields should reach the international advanced level. In August 2017, the State Council issued the guidance on further expanding and upgrading information consumption and continuously releasing the potential of domestic demand, proposing to carry out the pilot application of new technologies such as blockchain and artificial intelligence. In October 2017, the State Council issued the guidance on actively promoting the innovation and application of supply chain, which proposed to study the use of blockchain, artificial intelligence and other emerging technologies to establish a credit evaluation mechanism based on supply chain
in March 2018, the Ministry of instry and information technology (MIIT) issued the key points for standardization of informatization and software service instry in 2018, proposing to promote the establishment of the national informatization and instrialization Integration Management Standardization Technical Committee, and the national blockchain and Distributed Accounting Technology Standardization Committee. In June 2018, the Ministry of instry and information technology issued the instrial Internet development action plan (2018-2020) to encourage the application and research of emerging cutting-edge technologies such as edge computing, deep learning and blockchain in the instrial Internet
since the blockchain was listed in the 13th five year plan for national informatization for the first time in 2016, the national government has paid more and more attention to the blockchain. 24 provinces and cities or regions, including Beijing, Shanghai, Guangdong, Hebei, Jiangsu, Shandong, Guizhou, Gansu and Hainan, have launched dividend policies to carry out the layout of the blockchain instry chain, Actively explore instry applications based on blockchain
At present, China's blockchain technology continues to innovate, and the blockchain instry graally takes shape, and has begun to be applied in supply chain finance, credit reference, proct traceability, right trading, digital identity, electronic evidence and other fields, which is expected to promote China's economic system to achieve technological change, organizational change and efficiency change, To make important contributions to the construction of a modern economic system. With the continuous influx of entrepreneurs and capital, the number of enterprises is increasing rapidly. The application of blockchain will accelerate the landing, boost the high-quality development of traditional instries, accelerate the instrial transformation and upgrading, use blockchain technology to "rece costs" and "improve efficiency" for the real economy, and boost the standardized development of traditional instries. In addition, blockchain technology is becoming a new business form and a new driving force for economic development. Blockchain technology is promoting a new round of business model reform and becoming an important support for building a social system of integrity In the past, the circulation of physical banknotes was difficult to trace, but with the application of blockchain technology, the flow of all digital assets will have a "chain" to check. For example, in the financial field, blockchain is expected to solve the pain points and difficulties in the payment field, rece the complexity of transactions, improve the end-to-end speed of transactions, rece the communication cost in the transaction process, and improve the transparency and non tamperability of transaction records. The cost of reconciliation, clearing and settlement among financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution among financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In addition, the application of blockchain will also extend to many fields, such as health care, ecation, charity, social management and so on. The market prospect is very broaddefinition of blockchain
according to the definition in the white paper on blockchain (2019) issued by China Academy of information technology, blockchain is an accounting technology that is jointly maintained by multiple parties, uses cryptography to ensure the security of transmission and access, and can realize consistent data storage, difficult to usurp and prevent repudiation; In the people's Bank of China's "financial distributed ledger technology security specification", it is defined that distributed ledger technology is a distributed infrastructure and computing paradigm formed by the high integration of cryptographic algorithm, consensus mechanism, point-to-point communication protocol, distributed storage and other core technology systems
blockchain technology is a decentralized way to collectively maintain the trusted database technology, which has the characteristics of decentralization, tamper proof and highly scalable. It is rapidly integrating with the new generation of information technology such as big data, cloud computing, artificial intelligence and 5g, and has been applied to various important fields such as government affairs, medical care, public charity and judicial governance, It is expected to promote human from the era of information internet to the era of value Internet
blockchain development stage
in the past decade, blockchain technology has been continuously upgraded, and the instry divides its evolution and development process into three stages, which are not realized in turn, but a process of common development and mutual promotion
in 2020, the blockchain instry will be further standardized
in 2020, China's blockchain policy will continue to be favorable, the standards and specifications will be more perfect, the instrial scale will continue to grow, the technology will continue to innovate and develop, and the application demonstration effect in key fields will accelerate. At the same time, according to the problems existing in the development of China's blockchain in 2019, CCID blockchain Research Institute puts forward six suggestions: accelerating the formulation of top-level design, establishing and improving the regulatory system, accelerating the innovation and development of core technologies, promoting the third-party evaluation and certification, strengthening the cultivation of professional talents, and accelerating the implementation of applications in various fields
- the above data comes from the analysis report of China's blockchain instry market outlook and investment strategic planning of foresight Instry Research Institute
1. The "load" in dispatching is the electric quantity, unit: degree, also is kilowatt hour, kW & 8226; h;
load is not a constant value, but a variable value with time. Because the electrical equipment does not run at the same time, even at the same time, not all can reach the rated capacity. In addition, the working system of each electrical equipment is different, including long-term, short-term and repeated short-term
2. "Load" used in power flow calculation refers to the outgoing power flow of a node, which is the power
S=P+jQ
where p is active power
unit: W, kW, MW
q is reactive power, unit VaR, kvar, Mvar
s is complex power, unit VA, KVA, MVA
in design, if the capacity of each electrical equipment is simply added up as the basis for selecting conctor, cable section and electrical equipment capacity, the equipment will be under loaded, resulting in a waste of investment and non-ferrous metals; If it is too small, overload operation will occur
the result is either uneconomic, or overheating insulation damage and line loss increase, which will affect the safe operation of wires, cables or electrical equipment, and even cause fire accidents. Therefore, the load calculation is only close to the actual capacity
the total load of power system is the sum of the total power consumed by all electrical equipment in the system; By adding the power consumed by instry, agriculture, posts and telecommunications, transportation, municipal administration, commerce and urban and rural residents, the comprehensive power load of power system can be obtained; The power of comprehensive power load plus network loss is the power that each power plant in the system should supply, which is called the power supply load (power supply) of power system; The power supply load plus the power consumed by each power plant itself (i.e. auxiliary power) is the power that should be generated by each generator in the system, which is called the generation load (generation capacity) of the system
the load is a random change, every time the electrical equipment starts or stops, the corresponding load will change, which can be found to have a certain regularity to some extent. For example, some loads change to a certain extent with seasons (summer and winter) and enterprise working system (one shift or shift operation). The regularity of its change can be described by load curve: the so-called load curve refers to the graph of active and reactive load changing with time of electrical equipment in a certain period of time, which constitutes active load curve (P) and reactive load curve (q) respectively
the load rate required by different factories in different seasons is different, and the load rate issued by large factories and units is higher, which is for energy saving. When there is excess power, the generation of small units is usually limited, so the plants usually generate power according to the load curve issued by the dispatch, and the load rate is not assessed. Load rate = 24 hours average load / total adjustable output.
