Blockchain 30 real economy

1. This view is correct
blockchain technology, of course, is a new technology application after the development of Internet information technology to a certain stage. Once deeply integrated with the real economy, it is bound to promote the development mode and upgrading of the real economy, which is concive to saving resources, improving efficiency and recing costs.

Because the digital currency, which is the first generation of blockchain technology, has a huge impact on the financial field, the research and application of blockchain technology has become an important task in today's financial field. In essence, blockchain technology still belongs to a kind of technical means and tools. Its application in the financial field and the real economy is parallel. It has its own relative independence, but it also has a certain degree of intersection. That is to say, its role in promoting the real economy is indirect

No matter finance or entity, trust is one of the basis of transaction between supply and demand. The current bank to enterprise, enterprise to enterprise and enterprise to person are all linked by money. With the further popularization and wide application of blockchain technology, enterprises and enterprises, or indivials can issue digital currency (Digital credit) by themselves in the future, and the status of banks will change from monopoly operation to equal competition operation in the market. Therefore, the wide application of blockchain technology in the financial field has an indirect impact on the real economy

2. Blockchain technology is the bridge between reality (entity) and virtual world. Through blockchain technology, the real world can be reconstructed, reconstructed and redefined in the virtual world. For example, the digital currency of real paper money in the virtual world, the digital stock transaction of real stock transaction in the virtual world, the digital settlement, digital customs clearance, digital documents and bills of real import and export trade in the virtual world can greatly improve the efficiency of business process and save the transaction cost. At present, all transactions are inseparable from the bank. The bank plays a central role in the transaction. The application of blockchain technology by the bank will certainly improve the efficiency of its settlement and indirectly promote the efficiency of the real economy, but this impact will graally weaken in the future. Because the biggest feature of blockchain technology is decentralization, its distributed accounting system is a network system without center

3. The application of blockchain technology is actually to value and credit the current information flowing through the Internet. Through blockchain, the information with (use value, exchange value and cultural value) in the Internet is reorganized and reconstructed to form value Internet , which is of great significance, Whether it is to the financial instry or the real economy will bring revolutionary role in promoting

7. With the innovation and upgrading of blockchain, the deep integration of blockchain technology with more and more real instries plays an increasingly key role in promoting cross regional collaborative development of manufacturing instry, instrial interconnection, intelligent manufacturing, data sharing, and financial empowerment of real economy
the blockchain itself also needs to consider password security. Because blockchain is a kind of additional account book that can encode the effective transactions in the system by using cryptography technology, we must strengthen the security of the password itself. At the same time, the security of blockchain is the same as other important information systems, so the system security must be strengthened
from the perspective of talent supply side, the growth rate of blockchain talents can not meet the market demand. According to the data of LinkedIn in February 2018, the global demand for blockchain talents began to grow in 2015 and experienced explosive growth from 2016 to 2017. However, at present, its proportion in the total demand of the global talent market is still very low. In recent years, the instry with the fastest growing demand for blockchain talents is the computer software instry, followed by the financial services and insurance instry. From 2015 to 2017, the number of talents with blockchain related skills on LinkedIn's archives has increased nearly 19 times, but the total number of talents is still small, which is only about 2% of the global AI talents on LinkedIn's platform
the ecology of blockchain instry chain is graally forming. In 2018, the whole instry status, including hardware and infrastructure, platform and infrastructure, general technology layer and peripheral service layer, has made relevant progress. It has become a subversive and strategic key supporting technology, and also an important technology to promote the integration of digital economy and real economy
to enable the deep integration of digital economy and real economy, blockchain should further increase investment, strengthen basic research, enhance the original innovation ability, strive to occupy the commanding height of innovation and obtain new instrial advantages. In particular, the implementation of blockchain in China faces not only technical problems, but also challenges of market integration, talent training and legal system. At present, the entity enterprises' cognition of blockchain is relatively insufficient, and their awareness of change is not strong, which also restricts the development of blockchain technology in the field of manufacturing
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

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>

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
