Block chain in State Grid has one master and multiple slaves on

1.

blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects

on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention

on December 2, 2019, the word was selected into the top ten catchwords of "biting words" in 2019

extended data:

Application of blockchain Finance:

since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain Technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency

standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency

in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016

the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology

Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:

1, open source code

upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public

2, complete decentralization

anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"

3. Developing decentralized applications

through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers

4. I think it's the main chain

5. Many virtual currencies, once withdrawn from the exchange, have to be stored in third-party wallets such as imtoken. This is also forced helpless, because there is no own wallet, so can only "rely on others."
How can we live an independent life without looking at others? This will lead to a word: the main chain
the term "main chain" comes from the "main network" (relative to the test network), that is, the officially online and independent blockchain network
at present, among the top 50 blockchain projects in terms of market value, 12 projects are "main chain" (the current data has changed), and Ethereum is the most successful one
Ethereum is a main chain that has its own independent wallet and can "provide housing" for other currencies
next, through the analysis of Ethereum, we will give you an in-depth understanding of what is the main chain
most of the crowdfunding projects in the market are based on Ethereum. You can understand that Ethereum is a computer operating system, similar to the windows system, and the various tokens on Ethereum are equivalent to all kinds of software on our computers. Developers can pay Ethereum to run projects on Ethereum. However, Ethereum is not perfect. The more projects based on Ethereum, the greater the network demand for Ethereum. In serious cases, it will lead to congestion
in fact, most of the main chain projects are still in the stage of technology R & D and improvement, and there is still a long way to go before the real technology is implemented
the most fierce competition in the field of blockchain is actually the battle of "main chain". Whoever can become the main chain of the basic layer of the blockchain is likely to become the future giants such as apple and Microsoft
in addition, in the domestic public chain, the Walton chain is the underlying commercial application public chain, which combines the software level features of blockchain, such as decentralization and unforgivability, with the hardware of RFID chip independently developed, to provide traceability, authentication solutions, and design instry data encryption and distributed storage database building services for all walks of life
of course, it doesn't mean that projects with a main chain are better than projects without a main chain. Some projects, e to their nature, don't need a main chain, such as BNB, whose main purpose is to offset the handling charges in the currency exchange, so it doesn't matter whether there is a main chain
from bitcoin to Ethereum, and now to EOS, many gods are building the main chain, trying to climb the tide of the times. Who will be the future king of blockchain? Let time give us the answer.

6. Blockchain instry is developing at a high speed, helping the real economy to rece costs and improve efficiency
at present, a new round of scientific and technological revolution and instrial change sweeping the world, big data, cloud computing, Internet of things, artificial intelligence, blockchain and other new technologies continue to emerge, and the digital economy is profoundly changing the way of human proction and life, becoming a new driving force of economic growth. As a disruptive technology, blockchain is leading a new round of technological and instrial changes in the world, and is expected to become
the "source" of global technological innovation and mode innovation, and promote the change from "information internet" to "value Internet"
in China's 13th five year plan for national informatization, blockchain is regarded as a key cutting-edge technology, and it is clearly proposed to strengthen the innovation, experiment and application of new technologies such as blockchain, so as to seize the leading power of the new generation of information technology. At present, China's blockchain technology continues to innovate, and the blockchain instry has initially taken shape. It has begun to be rapidly applied in supply chain finance, credit reference, proct traceability, right trading, digital identity, electronic evidence and other fields. It is expected to promote China's economic system to achieve technological change, organizational change and efficiency change, and make an important contribution to the construction of a modern economic system
as of June 2018, China's blockchain related business has initially formed a scale under the promotion of the government, enterprises and capital, and is in the forefront of the world in terms of the number of patents, financing environment, policy support and application landing
the instry is developing at a high speed, and the number of enterprises is increasing rapidly
according to the statistical data of the "in depth analysis report on business model innovation and investment opportunities of blockchain instry" released by prospective instry research institute, there were 406 patent applications related to blockchain in the world in 2017, of which 225 were from China. As of the end of March 2018, the number of blockchain based companies in China has reached 456. The blockchain instry has initially formed a scale. From the upstream hardware manufacturing, platform services, security services to the downstream instrial technology application services, instry investment, media publicity, talent services and other instrial chain links are basically complete
from the change of the number of newly established companies in China's blockchain instry, the number of Companies in this field began to increase in 2014, and the number of newly established companies increased significantly in 2016, more than 100, more than three times of 2015. 2017 is the peak period of blockchain entrepreneurship in recent years. Due to the rapid popularization of blockchain concept and the graal maturity of technology, many entrepreneurs swarmed into this field, and the number of newly established companies reached 178
from equipment manufacturing to instrial application, the context of the blockchain instry chain is graally clear
from the distribution of newly established companies in the blockchain instry segmentation field, as of the end of March 2018, the number of instrial application companies in the blockchain field is the largest, including 86 companies serving the financial instry and 109 companies serving the real economy. In addition, there are more than 40 related companies in blockchain solutions, underlying platforms, blockchain media and communities
judging from the distribution of investment events in blockchain instry segments, companies related to instrial application services have the largest number of investment events, with a total of 113. It can be seen that investors are paying more and more attention to projects with specific application scenarios that can be actually implemented. The number of events in the field of underlying platform is 42, and the number of events in the field of blockchain media and community is 28. The field of blockchain is attracting more and more entrepreneurs and capital, becoming a new highland for innovation and entrepreneurship. With the development of blockchain technology and the acceleration of application, the instrial scale will continue to increase, and this field is expected to become a new economic growth point in the future
the influx of Internet giants has rapidly promoted the development of China's blockchain instry
blockchain technology is not only favored by start-ups, but also widely concerned by internet giants. Internet giants have expanded their blockchain business and rapidly promoted the development of China's
blockchain instry. At present, Tencent, Alibaba, Internet, Jingdong and other Internet instry giants have joined in the research and scenario application of blockchain technology
the regional distribution is relatively concentrated, and the instrial agglomeration effect is obvious
from the perspective of the regional distribution of China's blockchain companies, Beijing, Shanghai, Guangdong and Zhejiang are still the concentration places of blockchain entrepreneurship, accounting for more than 80% of the total. Among them, Beijing is in the absolute leading position with 175 companies, accounting for 38%; Shanghai ranked second with 95 companies, accounting for 21%; Guangdong Province ranked third with 71 companies, accounting for 16%; Zhejiang Province ranked fourth with 36 companies, accounting for 8%. In addition, Jiangsu, Sichuan, Fujian, Hubei, Chongqing and Guizhou are among the top ten provinces in China's blockchain entrepreneurial activity
the application of blockchain is diversified, extending from finance to the physical field
blockchain technology has the characteristics of distributed, tamper proof, high transparency and traceability, which is very suitable for the business needs of the whole financial system. Therefore, it has been applied in payment and clearing, credit financing, financial transactions, securities, insurance, leasing and other sub fields. For example, Minsheng Bank and China CITIC Bank jointly launched the first domestic L / C blockchain application, and Ping An of China's two major application scenarios of asset trading and credit reference have been online. China Merchants Bank has landed the first domestic blockchain cross-border payment application, and Weizhong bank has shortened the reconciliation time from t + 1 day to t + 0 day through the inter agency reconciliation platform based on blockchain, realizing daily quasi real-time reconciliation
with the graal maturity of blockchain technology innovation and development, the actual effect of instrial application has become more and more obvious
now, the application of blockchain has extended from the financial field to the physical field, including electronic information deposit, right management and trading, proct traceability, digital asset trading, Internet of things, intelligent manufacturing, supply chain management and other fields. Blockchain technology began to be deeply integrated with the real economy instry, forming a number of "instrial blockchain" projects, ushering in the era of "a hundred flowers bloom" of instrial blockchain
to realize "informatization of cooperation links" and help the real economy rece costs and improve efficiency
from the current actual landing cases, the landing application of instrial blockchain technology should solve some "small problems" for the instry realistically, and focus on improving the informatization level of instrial cooperation links, Specifically, we can promote the development of traditional instries from two aspects of "cost rection" and "efficiency improvement"
in addition to low cost and high efficiency, blockchain can also realize "trust transfer" or "trust spillover". Based on blockchain technology, since the information on the chain can not be tampered with, the third party can also trust the information after the two parties jointly verify a transaction, In fact, this kind of trusted state can be transmitted to a third party, and then realize the capitalization of data. In addition, it is very easy for institutions to turn from the "black box" state to the "white box" state, that is, the operational mechanism of institutions is transparent, which makes it very easy to prove their innocence and greatly reces the cost of mutual trust between multi-agent
furthermore, blockchain will play a role of "improving the efficiency of instrial chain collaboration". To improve the level of instrial collaboration is an important way to promote made in China to move towards the middle and high end, and also an important requirement for building a modern economic system. However, in many instries, the efficiency of instrial chain collaboration is still not high, especially in the field of international trade
technology abuse leads to certain risks in instrial development, which can not be ignored
although the positive value of blockchain technology is graally emerging, there are still a series of risks that can not be ignored in the process of instrial development. On the one hand, it is compliance risk. In the early stage of the development of blockchain, because it has the property of transmitting value, it has attracted some behaviors that are not focused on technology application, but are keen on illegal fund-raising, pyramid selling and even fraud through ICO (initial token issue)
the instrial policy system has been graally constructed, and the instrial development environment has been continuously optimized
the blockchain technology has risen to the level of national science and technology strategy. In December 2016, the notice of the State Council on printing and distributing the 13th five year plan for national informatization first mentioned blockchain, and took it together with quantum communication, artificial intelligence, virtual reality, big data cognitive analysis, driverless vehicles and other technologies as key cutting-edge technologies, clearly proposed the need to strengthen the innovation, testing and application of blockchain and other new technologies, In order to seize the leading power of the new generation of information technology. Secondly, relevant instry, national and international standards are also speeding up to solve the key technical standards of blockchain and promote the ecological development of blockchain instry. In order to grasp the development opportunity of blockchain instry and seize the commanding point of blockchain instry development, local governments timely issued blockchain technology and instrial development support policies, which ushered in a new outbreak of blockchain instry
at present, local governments are actively positioning blockchain technology from the perspective of instry and seizing the new opportunities brought by technology upgrading. For example, in March 2018, the Hebei provincial government issued the guiding opinions on accelerating instrial transformation and upgrading and building a modern instrial system, proposing to actively cultivate and develop future instries such as blockchain and build a world-class high-tech instrial cluster< According to the overall plan of the 19th National Congress of the Communist Party of China, preventing and defusing major risks is one of the priorities of China's economic work in the next three years, and the key to preventing and defusing major risks is to prevent and control financial risks. Therefore, China also actively strengthens instry supervision, prevents possible financial risks in the process of blockchain development, maintains the stability and security of national finance, and promotes the healthy development of blockchain instry, so as to better play the positive role of blockchain "value Internet"
blockchain is a cutting-edge technology, and the new regulatory challenges caused by technology also require the continuous progress of regulatory technology. "Reg tech" (regulatory Technology) in the financial technology segment. It is to use new technologies such as big data, artificial intelligence and blockchain to solve regulatory compliance problems and rece compliance costs. Blockchain filing platform and blockchain based regulatory system all belong to the field of reg tech. There have been companies engaged in regulatory technology in China, which mainly provide regulatory technology solutions for the government, major banks and other financial regulatory agencies. Jinqiu technology, zhongxiangbit and other companies have launched a supervision system based on blockchain.
