The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized

characteristics of blockchain Decentralization:
decentralization, not without the center, but by the node to freely choose the center, freely determine the center. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center
in a decentralized system, anyone is a node, and anyone can be a center. Any center is not permanent, but phased, and no center is mandatory for nodes
with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together

Bitcoin is not the only digital currency on the Internet. There are also ripple, stellar, litecoin, Ethereum and other digital currencies. Of course, the most popular is still bitcoin. But many times, some developers, entrepreneurs or enterprises will let us know that we need better digital currency. A programmer named Jed McCaleb, the father of electric donkeys, developed the reborn coin, which should be better than the bitcoin. Later, he launched the star coin, which is better than the reborn coin. What is more gratifying is that he is not fighting alone
now there is a trend that the instry hopes to develop a technology that enables all these online digital currencies to flow to each other, which means that you can transfer money freely in different online digital currency systems in the future. This technology is known as "interleaver protocol (ILP)", initiated by ripote. However, in recent months, that is, after the company released this idea, they also got the support of many famous companies in the instry, including Microsoft and the world wide web. Obviously, Ruibo currency company wants to set the technical standard of digital currency on the Internet. They want to develop a single global network, which can not only unify all digital currencies, but also unify all enterprises and indivials who use these digital currencies
"we want to be on a higher level and extract the differences between various digital currencies," said Stephen Thomas, chief technology officer of ripple. "We are trying to develop a global standard for payment."
with the launch of this agreement, we hope to enable more people to use online digital currency, expand the scope of use of online digital currency, and let us transfer funds more efficiently. This is actually the goal of many existing projects. For example, the original intention of the design of reborn currency and star currency is to allow users to transfer money to these two digital currency accounts in any currency, and to enable these two digital currencies to be converted into other currencies correspondingly. You can send bitcoin, and then the other party gets it. You can also send us dollars, and the other party will get dogecoin. However, for businesses and the developer community, there are restrictions on their use of these ledgers, so there are some problems because you can't transfer money from one payment network to another. Now, however, the interleaver agreement hopes to change that
to some extent, after ten years of efforts, they hope to develop a new network protocol, which is commonly known as "money Internet". If we go back to the early 1990s, we know that the famous Marc Andreessen founded the Netscape web browser. Now, the project hopes to play a similar role. They want to establish a standard way to send funds on the Internet. In fact, the original Hypertext Transfer Protocol (HTTP, which defined the basic standard of the network) contained code for payment. But this code has never been used. In recent years, many companies (such as coinbase, a bitcoin exchange, and stripe, a company that helps enterprises accept various online digital currencies) are at least trying to create a conventional standard for online digital currencies. In the future, we hope to be able to send and receive money online, just like sending short messages or e-mails. However, we still have a long way to go to this paradise, but at least now we are in the right direction
2. Risk control system: strict risk control system, asset abnormal alarm, timely detection of risk events, customizable script, Real time observation platform data. Intelligent monitoring of asset circulation, abnormal alarm, withdrawal blocking. The exchange looks simple, but when it comes to development, there are still many needs to be sorted out. We've been doing this for 12 years, so it's clear
blockdog is not a real blockchain game. It's Zijin disk, Chuanxiao disk. What model, of course, is the Ponzi scheme. If you are a gambler, you can help yourself
so what is a real blockchain game? It should have three points:
first, it should have blockchain wallet
Second, the game will indicate what kind of public chain is used, such as Ethereum or EOS
thirdly, pets, swords and other props in blockchain games can be found on the blockchain browser, and the information is public, such as the number, attack power and so on
a game without these three points is a fake blockchain game.
the digestive system of ants has a strong ability to kill bacteria. A kind of termite from the Philippines was used as an experiment to make it eat food containing cholera bacteria. After 9 hours, the ants were crushed, and no live cholera bacteria was found under the microscope. After feeding on Rickettsia typhi, the other ant could not find any living rickettsia from its feces. It can be seen that the digestive juice and formic acid in the digestive tract of ants have the function of disinfection and sterilization. After years of research, Professor Betty of Macleay University in Australia claimed that the reason why ants rarely get sick is that the ash like substance secreted by ants contains antibiotics, which can effectively control the infectious diseases in the ant colony. The latest research also confirmed that this "ant antibiotic" can help the human body resist a variety of pathogenic microorganisms, especially in the treatment of fungal infections and Staphylococcus aureus

why ants are called the "nutrition treasure house of micro animals"
through some domestic scientific research, medical institutions have carried out nutritional analysis on the commonly used wild improved species of mountain ant, and the sweat protein is 40% - 67%. The eggs are also similar, and 8 of the 19 amino acids contained in them are essential amino acids for human body. It contains vitamin A, vitamin B1, B2, B12 and vitamin C, D, e, etc; Inorganic salts contain calcium, iron, phosphorus, selenium, zinc and so on. Among them, zinc is the most abundant. The content of zinc per 1000 grams of ants is as high as 120-198 Mg (some can be as high as 230-285 mg), which is 8 times that of soybean, 11 times that of pig liver, 21 times that of egg and 40 times that of pork. It has become one of the most zinc rich foods. Microelement zinc is praised as "spark of life" by medical scientists and nutritionists. It is closely related to human growth, development and anti-aging.zinc can also prevent eye diseases, wrinkle, infertility and improve sexual desire. It can even prevent cancer, anorexia, obesity and osteoporosis. It can also promote immune skills, Patients with rheumatoid arthritis and elderly people with senile plaques are generally zinc deficient. From the perspective of zinc supplement, eating ants is very suitable and effective. It also contains a variety of enzymes, steroids, triterpenoids and so on

what is the effect of eating ants on human body
ant is a kind of mild health food. It is a good medicine for anti-aging and treating many kinds of deficiency diseases. From the perspective of traditional Chinese medicine, it is mainly for strengthening the body and strengthening the foundation, tonifying the kidney, nourishing the liver, promoting blood circulation and removing blood stasis, dispelling wind and cold, so as to achieve the purpose of strengthening the body and expelling evil and fitness. Modern scientific analysis shows that ants contain more than 50 kinds of nutrients necessary for human body and have a wide range of pharmacological effects such as anti-inflammatory, analgesic, liver protection, antispasmodic and antiasthmatic. It has been proved by immune function experiment that it can enhance immune efficiency, anti-aging, anti fatigue, enhance sexual function and adapt to two-way regulation. As a health food, ants can promote the growth and development of children, enhance the system and enrance of middle-aged and young people, delay aging and prevent many common diseases of the elderly. Ants also have the function of treating different diseases at the same time<

the history of edible and medicinal ants
China is the hometown of edible and medicinal ants, which has a history of more than 3000 years. Our ancestors began to eat ants from the discovery of bears, pangolins and other animals' strong ability to attract a large number of ants. The earliest recorded documents are "Zhou Li Tian Guan" and "Li Ji neize", which say: "she is for the emperor's food". She is a special sauce made for the leaders before the Zhou Dynasty to collect ant larvae and pupae, add cinnamon, ginger and other spices. It is said in the volume of Ling Biao Lu Yi written by Liu Xun of Tang Dynasty that "the chieftains in jiaoguangxi cave mostly take ant eggs and eat them clean. The bittern is regarded as sauce, or the cloud flavor is similar to meat sauce, which can not be obtained by officials or friends.". Li Shizhen, a great medical scientist of the Ming Dynasty, wrote in his great book compendium of materia medica: "ant, named Xuanju, is also called Ju. Fat Mayer, ants have the meaning of monarch and minister, so the word from the meaning, also known as clam. The big one is fat Mayer, also called ant. There are many kinds of ants everywhere, such as big, small, black, white, yellow and red. They live in caves and lay eggs. They live in high places and have teams. Its egg is named she, which is g by the mountain people, and some of them fight for stones. It was eaten by the ancients, so the beans fed by the officials of the Zhou Dynasty included oysters<

eating methods of ants
① dried ants are generally used for brewing wine. Half a kilogram (500 grams) of dried ant can make Baijiu 5 kilograms (5000 grams), soak for more than 20 days, drink slowly, drink half a kilogram each time, and then pour half a kilogram after drinking, until the end of the drink. Drink 2-3 times a day, 50-100g each time. (the degree and amount of alcohol depend on people's drinking ability and habits): after drinking this 5kg of ant wine, the remaining ant trunks will not be used, because the effective ingredients in ant trunks are released into the wine after they are soaked in the wine; Don't put the dried ants into your mouth to chew. It's too thick and hard to absorb and swallow
2. Take ant powder three times a day, 5 grams each time. It's better to take it after meals, especially for those who have a lot of stomach acid, they should take it after meals (about half an hour). Because ants contain formic acid, some people who have a lot of acid in their stomach feel uncomfortable in their stomach or abdomen (bloating, stuffy or slight pain). In this case, they can take it in an appropriate amount and take weishuhu tablets. When taking ant powder, you can put it into your mouth first (5g, about half a teaspoon, more or less, no matter. Some people can take 7g-8g for the first time), and then drink one liter of boiled water. The ant powder dissolves quickly in your mouth, and you can swallow it into your stomach. Then you can drink a few mouthfuls of boiled water. This kind of eating method is fast and convenient. In order to make your taste better, you can also mix honey and ant powder well before taking it, Half a kilogram of ant powder About 50 grams of honey, mix well, fill with a covered container, half a tbsp to 1 tbsp each time If you are suffering from diabetes, it is not appropriate to take this method, because people with diabetes should not eat sugar). Generally, a pack of 450-500g ant powder can be taken for one month, and three packs can be taken for three months. For a course of treatment. Some people want to buy ants to dry them and then grind them into powder by themselves, which is a waste of trouble, because ants have heavy oil content (especially in winter), so it's hard to grind them into powder. The powder we proce is 100z pure ant powder, and it doesn't mix with other things
③ take ant powder capsules one by one three times a day, about 5 capsules each time (it's OK to take more children's capsules). Generally, 100 capsules are packed in each bottle. The dosage per person is 5 bottles per month, and 15 capsules are used for a course of treatment (three months). It's the most convenient to eat the capsules and the taste is better.
