How does blockchain affect consumption

1. 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

With the birth of new technologies and the popularization of new applications from generation to generation, it may be more convenient, faster and safer for ordinary people. Once the infrastructure is built, even the existence of technologies, such as e-shopping and mobile payment, has become a necessity in life

the evolution of blockchain and other technologies is full of opportunities and challenges, as well as unlimited possibilities. For example, in security, many experts mentioned quantum technology. Although it is still in the research stage, the change brought by encryption based on quantum entanglement is bound to be huge and profound

4. It's equivalent to 20 M broadband, one yuan a day at most. Now it's all subsistence allowances. I have 50m broadband in my home, which costs 1.3 yuan a day at most.

5. Blockchain technology is not omnipotent. At present, it is still in the stage of incompetence. Blockchain technology is not mature at present! It's too early to talk about the application of an immature technology all day long. Some Internet listed companies come out to talk about what blockchain technology breakthroughs they have made, how they plan to apply them, or what proct applications based on blockchain technology they have launched. In my opinion, most of them are pretentious and have no real use. At present, it is not to decide how to apply it, but to study and develop the technical reserve of blockchain. It's hard to do a good job of technical update by parroting!

6. Blockchain exploded at the end of 2017. It was influenced by the soaring bitcoin, thunderbolt, storm broadcast, cloud control, Renren blockchain and even Kodak. For a time, the slightly strange technology of "blockchain" seemed to be a magic drug for the stock price to come back to life. Even the prices of counterfeit tokens related to blockchain are like flying
different investors have different views. No matter they think it's a bubble sworn faction, or they regard it as a good candidate for the draught, they do not deny that the block chain is a tool that people can not ignore to change the society. Therefore, it is an important choice to join the blockchain investment platform.

7. As we all know, food safety is an issue of great concern to us. In fact, this problem can be avoided by technical means. Like the blockchain traceability solution of wangchain technology, they record the whole process of a commodity from proction to sales with the non tamperable properties of the blockchain, and then scan the QR code to know all the information of the commodity.

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. How much combat power should be suitable for monk Sha? It should be said that he is a more powerful character in the game, and his combat power must be at least above medium level to have a comparative advantage

10. For the problem of the owner
1: 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.
