The impact of blockchain on global industrial structure

1. Hello, as far as I know
the theme of this conference is technology restructuring the world
the vision is to drive a happy world and link to a better future
as for the impact on the future, different people have different opinions.

2. Chongqing jinwowo analyzes the impact of blockchain technology on the instry: blockchain will determine the relationship between people and all the Internet including artificial intelligence. The change of this relationship will have a subversive impact on the mainstream Internet business model and create a new era of decentralization.

3. Blockchain technology is a new development of Internet technology and modern information technology. It plays an important role in China's real economy and supply side structural reform. Promote the R & D and application of blockchain technology, deeply integrate with the real economy, and create an advanced manufacturing instry. It can realize the high-quality development of China's economy and is an important driving force for the construction of a modern economic system.

4. First of all, blockchain is likely to become the next important goal of e-commerce, which has been revealed in the larger instry participants. Alibaba has invested heavily in the research and development of blockchain and other large e-commerce companies (such as Wal Mart and Unilever) to cooperate with IBM, a technology giant, to enter the blockchain
secondly, for e-commerce, the smart contract of blockchain allows buyers and sellers to conct direct transactions. Smart contracts can be set to be executed only when specific obligations are fulfilled. For example, the buyer can send the determined price of the proct to the contract in cryptocurrency. The seller sends the proof of ownership to the smart contract and connects the smart contract with the company that transports and sells the proct. Once the seller has fulfilled all the obligations, the smart contract will automatically send the funds to the seller's wallet< Then, e-commerce has encountered setbacks in international transactions. But the company that can create a country and currency agnostic solution with blockchain technology is the request network. This blockchain based platform is eager to create a decentralized platform to provide convenient, fast and secure transactions for B2B, B2C and C2C interactions
finally, another disruptive function of blockchain technology is that it allows non corrupt visualization of the supply chain. We haven't done that yet, because blockchain still needs a lot of adoption, but once this happens, the whole chain reaction of the proct can be directly displayed with a tap of the thumb. Whether the proct is real, organic, fair trade or contains chemicals can be seen directly on its blockchain. Since the blockchain is not corrupt, it allows a completely transparent supply chain, allowing consumers to fully understand the procts they consume
with the progress of technology, blockchain will bring convenience to e-commerce in some other ways
welcome to pay attention to pinecone blockchain for more information.

5. Good bitcoin. My name is Lei Feng

6. Hehe, I just went there to sign up for a taxi yesterday. When I came back, I saw No.79 passing by our house. Another one was No.51. Look how many routes there are in your house. You can get on the bus and ask the driver where to get off~

7. Maybe, if you dig up krypton gold again and again, you'll make a lot of money. It's usually less than 100 grams an hour.

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

9. In just a few years, blockchain has developed from 1.0 era to 3.0 era. The update of each "era" has brought changes to the world. The development of blockchain can be divided into three stages from 1.0 era to 3.0 era: point-to-point transaction, transaction and transaction Smart contract and blockchain application Ecology (token economy)
blockchain 1.0 era: digital currency rate of return is the king

blockchain 2.0 era: smart contract provides infrastructure support for upper application development

blockchain 3.0: the subversion of business lies in the transformation of proction relations

all obstacles to the development of human society, Fundamentally speaking, they are all caused by "mutual distrust", especially various economic and financial crises. If human beings can solve the problem of mutual trust, then human beings will complete a very big leap forward
the development of blockchain has graally laid the foundation for this direction. Human beings are entering the era of "smart contract", which is the process of upgrading human trust mechanism. Once the smart contract is reached, human society is facing a new big upgrade. As a value creator, the value created by each indivial can be accurately recorded and the corresponding return can be obtained, There will be less and less mutual interference, and people are really moving towards independence and equality. Human civilization has evolved from "identity society" to "contract society", and blockchain is expected to lead human beings to transition from "contract society" to "smart contract society"
although blockchain has gone out of the conceptual stage, the current situation of blockchain technology development is that the underlying technology is not mature enough and the application scenarios are relatively limited. On the one hand, consensus algorithm and other core technologies of blockchain still have room for optimization and improvement; On the other hand, the processing efficiency of blockchain is difficult to meet the requirements of some high-frequency application environments in reality. Moreover, the current mainstream blockchain technology platforms are originated from foreign countries. Domestic blockchain technology service providers should patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the global blockchain technology development. It still needs a certain period of time. It can be said that the whole domestic trend is waiting for the emergence of a super level blockchain project
