Development trend of blockchain entities

1. blockchain instry has great growth potential. Five aspects promote the healthy development of technology. Blockchain basic situation analysis blockchain technology, as a technical solution for collective maintenance of a reliable database in a decentralized way, has the characteristics of decentralization, tamper proof, highly scalable, etc., and is becoming a new technology following big data, cloud computing, artificial intelligence Virtual reality and other technologies are another emerging technology that will have a significant impact on the future, which is expected to promote human beings from the era of information internet to the era of value Internet. Some countries and regions in the United States, Japan and the European Union have promoted the development of blockchain as an important national development strategy, and vigorously promoted the research and development and application of blockchain technology. China also attaches great importance to the technological innovation and instrial development of blockchain. With the joint participation of it and other enterprises, a large number of new enterprises, new procts, new models and new applications have emerged. The application of blockchain in the fields of finance, government affairs, energy, medical and other instries has graally expanded, and is becoming an important force to drive the technological proct innovation and instrial transformation of various instries. The development of blockchain can be divided into three stages, namely, blockchain 1.0, represented by bitcoin and related financial infrastructure applications, and blockchain 2.0, represented by smart contract. At present, it is graally moving towards blockchain 3.0, which is based on blockchain technology and more complex in-depth application of smart contract. Statistical analysis of blockchain investment and financing in the first half of the year since 2016, the frequency and amount of investment and financing in China's blockchain field have increased sharply. According to the statistical data of "in depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, in the first half of 2018, the amount of financing in the blockchain field was about 10.7 billion, with a year-on-year growth rate of 1426% compared with the same period in 2017; The number of investment and financing events in the field of blockchain has reached 205, and it is expected that the investment in the field of blockchain will usher in another peak this year. Judging from the distribution of investment and financing rounds in China's blockchain field, the investment rounds in the start-up period (before round b) account for more than 95%. There are many instry pioneers participating in the investment together, and most enterprises are still in the race. Statistics and growth of blockchain investment and financing in the first half of 2014-2018 data source: prospective instry research institute collated the statistical analysis of Chinese blockchain enterprises and registered capital. In 2013 and before, there were only 26 blockchain related enterprises registered in China. In 2016, 116 blockchain enterprises were registered, 158 were registered in 2017, and 52 were registered from January to the end of June 2018. In terms of registered capital, there are 26 enterprises in China whose registered capital is less than 1 million yuan, accounting for about 6%; 197 companies have registered capital between 1 million yuan and 9.99 million yuan, accounting for about 46%; There are 171 companies with registered capital between 10 million yuan and 100 million yuan, accounting for about 40%; There are 31 companies with more than 100 million yuan, accounting for about 7%. Statistics on the enterprises and registered capital of China's blockchain enterprises from January to June 2013-2018 data source: prospective instry research institute collates the statistics of China's blockchain enterprises in terms of regions and fields. Among the 425 blockchain enterprises, 385 enterprises are gathered in Beijing, Shanghai, Guangdong, Zhejiang, Sichuan and Jiangsu, accounting for 90% of the total. Among them, Beijing has the largest number of enterprises, accounting for about 37% of the country. In terms of instry, China's blockchain enterprises are mainly distributed in the fields of finance, bottom public chain, enterprise services, technical solutions, data services, health care, Internet of things, transportation, games, etc. Among them, 91 enterprises are engaged in the financial field, accounting for more than 21%. China's blockchain enterprise field distribution statistics data source: prospective instry research institute collates that China attaches great importance to the development and application of blockchain technology. Driven by multiple forces such as policy, technology and market, the pace of blockchain innovation has been accelerating. It has been deeply integrated with cloud computing, big data, Internet of things and other technologies. The scope of exploration and application has also expanded from digital assets to supply chain management, intelligent manufacturing, instrial Internet, social welfare, right protection and other fields. Five aspects to promote the healthy development of blockchain technology, and promote the high-quality development of digital economy. 1. Pay close attention to the international development frontier, jointly promote the research of blockchain related technology and instry, promote the standardization of blockchain development instry behavior, and create a good development environment. 2. Strengthen the construction of blockchain core technology capabilities. Establish and improve the collaborative promotion mechanism among backbone enterprises, universities and research institutions, guide it enterprises to strengthen technical reserves, accelerate the breakthrough of key core technologies, and improve the performance, efficiency and security of blockchain. 3. Support the development of entrepreneurship and innovation in the field of blockchain, encourage the cross-border integration of blockchain enterprises and user units, guide instry organizations to establish public service platforms, support third-party organizations to carry out blockchain service evaluation and testing, promote the enrichment of instrial applications of blockchain, and serve the transformation and upgrading of entity economy. 4. Actively build and improve the blockchain standard system, accelerate the development and application of key standards, and graally build a perfect standard system. Actively connect with ITU, ISO and other international standards organizations, substantially participate in more international standardization work, and actively contribute more "Chinese power". 5. We will accelerate the improvement of the policy environment for blockchain development, support qualified enterprises to carry out application innovation and mode innovation, and guide and encourage enterprises, universities and scientific research institutes to jointly cultivate professionals needed for blockchain development. Support eligible blockchain enterprises to enjoy the preferential tax policies of the state to support the development of software instry and small and medium-sized enterprises. The instrial scale is small but the growth potential is huge. The blockchain economy is on the eve of the outbreak period. The financial instry is relatively widely used, and the application of other instries has also entered the stage of exploration and development. It is estimated that the direct market value of blockchain will increase from US $410 million to US $7.68 billion between 2017 and 2022

2. Driven by policy and market, blockchain instry has a bright future
driven by policy and market, China's blockchain related instries are expected to move from virtual to real
in the context of rapid development of blockchain, China should comply with the needs of globalization, keep up with the international pace, and actively promote the research, standardization and instrialization development of domestic blockchain related fields. Compared with the increasingly stringent supervision of bitcoin and other digital currencies, the support and encouragement of blockchain technology has reached a consensus in the world, and the domestic blockchain technology will also receive national and local policy support in the next few years. Driven by policy and market, blockchain related instries are expected to move from virtual to real, and blockchain technology will accelerate the exploration of possible application scenarios< According to the data of the "in depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, the global blockchain market scale is expected to increase from US $411.5 million in 2017 to US $7683.7 million in 2022, with a compound annual growth rate of 79.6%. In view of the wide application range of distributed ledger, the rising market value of cryptocurrency, the strong demand for improving transparency, security, efficiency and simplifying process, and the popularity of blockchain as a service (
baas), the blockchain market will expand rapidly. In addition, communication services, international trade, supply chain management, programming platform, payment, smart contract, digital authentication and so on are also in urgent need of blockchain technology, which will create a lot of growth opportunities
as an integrated application of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other technologies, blockchain has become a research hotspot of the United Nations, the International Monetary Fund and other international organizations as well as many national governments in recent years, and the instry has also increased investment. At present, the application of blockchain has extended to the Internet of things, intelligent manufacturing, supply chain management, digital asset trading and other fields, which will bring new opportunities for the development of cloud computing, big data, mobile Internet and other new generation information technology, and have the ability to trigger a new round of technological innovation and instrial change
by 2022, the payment sector may occupy the largest share of the blockchain market
relying on blockchain technology, real-time payment of assets can be realized, which not only has the characteristics of tamper proof and digital authentication, but also can greatly save the cost of settlement for financial institutions and banks. In addition, blockchain makes payment automation possible, eliminates the need for middlemen, and saves labor costs and time for buyers and sellers. Thanks to the above advantages, it is expected that the payment sector will be the heaviest one in the whole blockchain market
the fastest growing region will be the Asia Pacific region.
blockchain service providers in the Asia Pacific region are good at designing and developing cryptocurrency platforms with friendly interface, cost saving and high speed, and extending the application of blockchain in many instries. Both large enterprises and small and medium-sized enterprises are actively seeking risk financing, investing in and developing the most cutting-edge blockchain technology. In addition, the real estate instry of some countries in the Asia Pacific region is expected to rapidly transform from translucency to full transparency, which also helps to enhance the development prospects of blockchain in the Asia Pacific region.

3. As people in the instry, what they see is that the waves are sweeping through the sand and the fittest survive. Those unreliable and pure deceptive blockchain projects will die faster in the cold winter. Even if they don't die, they will die. And companies that really have the strength to study blockchain technology will have a greater probability of survival, and then take off in the next bull market
in terms of currency price, the bull market should still be in 2019 as a whole, because bears are long and cattle are short
there will be more breakthroughs and developments in technology and commercial applications in 2019.

4. Since 2018, the blockchain instry has been booming. The exploration and application of blockchain is not limited to the underlying platform. Internet giants and financial giants have strengthened the application of blockchain in finance, public welfare, commodity traceability and other fields, especially in the financial field. The application with blockchain technology as the core has been accelerated
the blockchain instry is in the stage of rapid development
China's blockchain instry is in the stage of rapid development. According to the data of the "in-depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, by the end of March 2018, the number of blockchain companies with blockchain business as the main business in China has reached 456, from upstream hardware manufacturing, platform services, security services to downstream instrial technology application services, To ensure the development of the instry investment and financing, media, talent services, companies in various fields have been basically complete
according to the classification of application scenarios of top 20 enterprises in the ranking list, in addition to 13 enterprises focusing on the infrastructure and platform construction of blockchain such as underlying platform and blockchain hardware, the application scenarios of blockchain have graally enriched. According to the distribution of instry segments, there are 7 instry application companies, mainly Internet companies (Alibaba, Jingdong, Tencent) used in public welfare and commodity traceability, and innovative financial technology applications evolved by financial enterprises (Ping An, CMB, BOC), such as supply chain finance, bills and transaction clearing
as the blockchain can realize the non tampering of information, the possibility of data falsification is eliminated from the root, especially in the financial instry, which has high requirements for real data, it will embrace the blockchain more actively
analysis on the development trend of blockchain
Second, 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
fourthly, blockchain creates a new platform economy and opens a new era of sharing economy
fifthly, blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy< Sixth, the blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidated
in addition, as an emerging technology, there are still many technical difficulties in the application of blockchain in the actual proction environment of the financial instry, such as throughput, scalability, consensus mechanism, privacy and security, manageability, etc
technological innovation such as blockchain is of great significance to the financial instry, which is expected to accelerate the process of "credible digitization" and continuously drive the financial instry to "move from virtual to real".

the research process of instry technology is constantly advancing

in recent years, the research process of global blockchain technology has accelerated, and the number of instry patent applications has increased rapidly. According to sopat statistics, from 2014 to 2018, the number of global blockchain patents continued to rise, and by 2018, the number of global blockchain patent applications had reached 2966. Among them, the number of patents in China's blockchain in 2018 accounted for 33.33% of the total number of patents in 2014, and increased to 82.1% in 2018

however, despite the continuous development and innovation of global blockchain technology in recent years, there is no universal evaluation standard and system to specify the technical performance, efficiency, scalability, security and other issues of blockchain. On the whole, blockchain technology needs further breakthrough

China's blockchain technology tends to serve applications

in terms of technology, the core of China's blockchain technology is to serve physical applications, while the US blockchain technology is still solving the potential problems of blockchain, which leads to the domestic focus on alliance chain applications, We hope to optimize the blockchain technology to meet the requirements of high concurrency applications; Foreign countries focus on the application of public chain, and carry out the optimization and innovation of core technology according to the characteristics of public chain. In terms of application, domestic blockchain focuses on the application of service instry and tends to be "non currency blockchain"; Most of the U.S. is a public chain, which tends to the circulation of digital assets

6. In the future development of jinwowo analysis blockchain technology, under the premise of the continuous improvement of the blockchain technology regulatory system, the development momentum of blockchain technology will be better than it is now, and the whole world's acceptance of it will be higher and higher.

The sudden epidemic situation has pressed the "pause" button for many instries, but science and technology is the most effective means to fight against disasters. Blockchain technology has realized the combination with finance, logistics, supply chain, government affairs, public welfare, urban management and other application fields. At the same time, e to the imperfect development of technology, the role of blockchain in the prevention and control of the epidemic is very limited, so we need to explore deeper scenario applications

from the survey data, the main application directions of instrial blockchain in the post epidemic period include: traceability, financial (including insurance) supervision, collaborative sharing. Deposit certificate, digitization, credit investigation, digital asset transaction, etc

in the main application direction of instrial blockchain in the post epidemic period, more than 70% of enterprises choose traceability and financial (including insurance) supervision, in addition to collaborative sharing and certificate deposit. Digital also has more than 60% of the enterprise choice, compared with the low choice rate of credit reference and digital asset transaction, in which the choice rate of digital asset transaction is less than 50%, only 48%

to avoid risks and promote the healthy development of instrial blockchain

as an emerging technology development direction and instrial development field, blockchain has been widely concerned. The application of instrial blockchain is accelerating, which is mainly reflected in two aspects:

first, in the past, open source systems were represented in technology, and most of them were open source projects oriented to consumers, but now many projects oriented to instry and enterprise characteristics have been added; At the same time, more and more enterprises such as Internet giants and high-tech enterprises begin to enter this field, indicating that the era of instrial blockchain has come

secondly, the emergence of blockchain reces the threshold of trust and the cost of realization, enabling some financial and trade scenarios that could not be realized before to be realized. In this way, some new financial forms can be derived, providing more space for financial innovation

although the application of instrial blockchain is speeding up, it is still in an early stage of development. This is mainly reflected in the fact that blockchain technology alone can not fully solve the trust problems and information island problems between entities, and the emergence of blockchain technology also puts forward new problems for the current law and regulation

because of its decentralized and difficult to tamper with characteristics, blockchain has become a comprehensive subject driven by technology and deeply affecting economy, finance, society, organizational form and governance. In addition, blockchain technology is not yet fully mature in system stability, application security, business model and other aspects, which puts forward requirements for privacy protection and storage capacity of data on the chain

it should be noted that the current blockchain instry has been involved in many technical fields such as it, communication, security, cryptography and so on. What it needs is a kind of compound talents, which poses new challenges to personnel training and school ecation

the short-term impact of blockchain should be treated calmly to avoid overestimation. At the same time, it is necessary to further strengthen laws and regulations and supervision to avoid the possible risks of blockchain technology, so as to promote the healthy development of instrial blockchain

Selenium is a chemical element and a nonmetal

There are two forms of selenium in nature: inorganic selenium and plant active selenium. Inorganic selenium generally refers to sodium selenite and sodium selenite, which are obtained from the by-procts of metal deposits; The latter is formed by the combination of selenium and amino acids through biotransformation, and generally exists in the form of selenomethionine

There are four main functions of selenium:

1. Scientific confirmation: it is precisely because of & quot; Selenium & quot; It can prevent organ aging and pathological changes, delay aging, enhance immunity, resist diseases, resist toxic heavy metals, rece the side effects of radiotherapy and chemotherapy, and prevent cancer

Second, to prevent diabetes. Selenium is an active component of glutathione peroxidase (GSH PX), which can prevent pancreatic islets β Cell oxidative damage, make its function normal, promote sugar metabolism, rece blood sugar and urine sugar, improve the symptoms of diabetic patients

Third, detoxification and detoxification. Selenium has a strong binding force with metal and can resist the toxicity of cadmium to kidney, gonad and central nervous system. Selenium combines with mercury, lead, tin, thallium and other heavy metals in the body to form a metalloselenoprotein complex and detoxify

Prevention and treatment of liver disease. After 16 years of epidemiological investigation of liver cancer in China, Chinese medical expert Yu Shuyu found that the selenium content in the blood of residents with high incidence of liver cancer is lower than that in low incidence area of liver cancer. The incidence rate of liver cancer is negatively correlated with blood selenium level. She added selenium to 130 thousand residents in Qidong County of Jiangsu Province, and confirmed that selenium supplementation reced the incidence rate of liver cancer by 35%, and the incidence rate of liver cancer was 50%. p>

extended data :

don't blindly supplement selenium, the key to a balanced diet

in recent years, many people have joined the "army of selenium supplement", believing that selenium supplement is helpful to "cancer prevention". However, this practice is not worth encouraging, because selenium, like other trace elements, should adhere to the principle of appropriate amount, not more is better, and it is not suitable for everyone

selenium has such a strong anti-cancer effect. The results of the study have not yet been reached. Some studies have shown that selenium can rece the incidence rate of some cancers, but some studies have negated this conclusion. Therefore, the scientific research evidence of selenium as an anticancer agent is still very limited

The range between the beneficial and toxic amounts of selenium is the narrowest among all trace elements, so the most technical content is required for selenium supplement, and it will be excessive if you are not careful. Under normal circumstances, the recommended daily selenium intake is 50 ~ 200 μ G

In addition, excessive supplement of selenium will hinder the absorption of manganese in human body, and lack of manganese will cause a series of health problems. Therefore, we can not blindly supplement selenium. Some researchers warn that blind selenium supplement may increase the risk of some diseases. If you want to supplement selenium, you should go to a regular hospital to determine the level of trace elements in the body, and supplement selenium under the guidance of doctors to avoid poisoning

human body can not synthesize selenium itself, and food is the main source of selenium. A healthy person who is not partial to or picky about food can meet the body's demand for selenium through a balanced diet without additional supplement

all kinds of selenium rich foods on the market, such as selenium rich rice, selenium rich vegetables, etc., can be eaten occasionally, but it is not necessary to buy them often. If you must eat selenium rich food, it's best to choose the one marked with selenium concentration, calculate the body's needs and then buy it

The content of selenium in natural food was as follows: animal viscera, seafood, fish, eggs, meat, grain, milk, onion, garlic, vegetables and fruits. Sesame and garlic also contain a lot of selenium. The selenium content of the same crop in different areas is very different, and there is an order of magnitude difference of 1000 times or even 10000 times
