An empirical study on the impact of blockchain on consumption
in short, blockchain is a community-based technology, which can make value exchange more secure. Blockchain is their name
therefore, chain operation has a huge impact on the people, creating the greatest value for the enterprise and bringing more convenience to the people strong>
in a word, jinwowo thinks that this technology can solve many problems, but not every problem is suitable for blockchain technology! Moreover, blockchain technology itself is still in the development stage, and there are still many bottlenecks to overcome. If there is popularization in the future, it will have the same subversive impact on human society as the Internet
in the future, jinwowo will continue to tap the value of blockchain technology in the commercial field and give full play to the advantages of big data services
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.
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 P>
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 poisoninghuman 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 times1: bitcoin has no traditional state or institution guarantee, only network credit guarantee. Of course, the latter is not more secure than the former. But in fact, the legal currency guaranteed by the state or institution you mentioned has been depreciating rapidly. You can calculate how much the RMB in your hand has depreciated in the past two years, and then look forward ten years to calculate, and finally calculate how much your income has increased
2: the issuance of legal money does not rely on any resources and the increase of gold. What we need to do to issue legal money is to start the banknote printing machine. The Bretton Woods system has already collapsed. You don't think that every RMB can correspond to a certain ratio of gold. Compared with the over issuance of legal currency, the amount of bitcoin is negligible
3: deflationary currency, I won't go into details
4: as for the change of the index, if you are upset by the speculation of some speculators, I believe there is no reason why you should not spray a shares. Bitcoin is speculation, of course, but a shares are also speculation. Have you ever seen anyone who makes value investment in a shares and is still alive
5: no one knows who Nakamoto is, let alone who he is from. The old man in the news was fake, and he himself denied it. I believe that an alt with independent thinking ability still has the ability to distinguish the authenticity of news
6: of course, bitcoin is speculation. Stocks, futures and China's financial market are playing with speculation.
