The impact of blockchain on house prices
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
for example, if RMB with a face value of 500 is issued, will it affect house price?
blockchain is not easy to do since 18 years ago. The instry is deceptive, professional cut leek. I remember that the blockchain network reported that Li Xiaolai was cutting leeks. Li Xiaolai was going to build a blockchain network, so that their second round of financing had stopped. It was said that they had sold it to a technology company in Guangzhou
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.
Specifically, users can share the idle storage space and bandwidth resources of cat disk, and these resources will be output to companies such as content, video, game, blockchain, etc. cat disk company will convert the legal currency and various digital currencies paid by the latter into bitcoin, and users will get the corresponding bitcoin income. This is also the unique mining mode of cat disk
why reward bitcoin
because similar procts on the market reward users with points, diamonds and other rights and interests issued by relevant companies, and most of these rights and interests are of low or no value. In addition, those projects that once seemed to be hot are now almost withered, and the early players may benefit, while the late players will lose all their money
as we know, bitcoin is the anchor currency in the digital currency world. Cat disk directly uses bitcoin to motivate users, and users can pick up the coin to their wallet at any time, and their income can be guaranteed. Moreover, the risk of bitcoin breaking is almost zero, and the user's income will be more lasting and stable
how is the mining income distributed when it comes to distribution, we should first introce the concept of "storage power", which is directly linked to the income of cat disk users. Storage power is an index based on users' shared storage space, bandwidth and online time. The larger the storage space, the faster the bandwidth speed and the longer the online time, the larger the storage power, and vice versa the cat disk gains revenue by sharing storage bandwidth resources, and users can check the revenue through app every day, that is, how much bitcoin they earn. The profit distribution of maopan mining is not random, but through a series of calculations. In short, users' daily income depends on their personal storage capacity, all users' storage capacity and the amount of money issued each day. The calculation formula is as follows: single user's daily income = single user's daily storage capacity / all users' daily storage capacity * Daily currency amount it can be seen that users' daily income is positively correlated with the daily storage capacity index and the daily currency amount, and negatively correlated with all users' daily storage capacity index what is the amount of money issued every day the cat disk integrates the storage and bandwidth resources shared by users, provides storage and bandwidth services to the demander, and converts various digital currencies paid by the other party into bitcoin for distribution to users. How much bitcoin is issued every day depends on the actual business situation, so there is no way to give specific figures for the time being. What we can make clear is that, unlike other mining procts, cat disk does not issue its own currency or restrict the mining of a specific kind or several kinds of currency. Instead, it earns various digital currencies paid by others. These currencies are all market currency. Cat disk converts these currencies into bitcoin and distributes them to users note that all the currencies are negotiable, and the more storage nodes, the more business, the higher the overall mining revenue; For other mining procts, the amount of money that can be mined is limited or issued by the owner. With the passage of time, there will be more and more mining machines, and the mining income will be less and less
the first supercomputer to be provided by IBM is called ASCI purple, and its computing speed will reach 100 trillion times per second, that is, the level of teraflops. The computer is considered a direct descendant of deep blue. Dark blue was made by IBM in 1997 and was used to play chess with Garry Kasparov, then the world champion of chess
the second supercomputer is currently named blue gene / L, and its computing power will significantly exceed ASCI purpose, reaching 360 trillion times per second. It is expected to be delivered in 2005. The Department of energy plans to use the computer for national laboratories such as Los Alamos, Sandia and Lawrence Livermore to simulate weapons, biotechnology and high-energy explosions.
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 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 times
