Blockchain experience Officer
blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. In essence, it is 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 a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:
1. The blockchain with the whole network open and without user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain
blockchain features
1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
Blockchain technology is widely used. Under the integration of new technologies, the main application scenarios of blockchain include finance and insurance, intelligent manufacturing, intelligent environmental protection, energy and power, health care, ecation, culture and innovation, smart city, social welfare, agriculture and many other fields

3. Blockchain + government
in statistics, voting, budget management and other aspects, blockchain can rece costs, improve efficiency, and increase transparency, so as to prevent the risk of failure of centralized system
4. Blockchain + insurance
fraud identification and risk prevention: by placing insurance claims under an unchangeable general ledger, blockchain helps to eliminate the common sources of fraud in the insurance instry
property insurance and accidental injury insurance: policies and shared ledgers recorded in the form of smart contracts can improve the efficiency of property insurance and accidental injury insurance
Health Insurance: blockchain technology enables medical records to be encrypted and shared among health service providers, thus improving the interoperability of the health insurance ecosystem
Reinsurance: the information security of reinsurance contracts on the blockchain platform can be ensured through the form of smart contracts, which can rece the amount of information and simplify the payment process between insurers and reinsurers
different from other app stores, chainstore can not only download blockchain instry applications, but also browse the latest airdrop candy information and high-quality blockchain projects. It is an app that provides comprehensive services for the blockchain instry.
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 amino acids do ants contain
amino acids are organic compounds containing amino (- NH3) and carboxyl (- COOH), which are the basic units of proteins
according to the analysis of Guangxi University of traditional Chinese medicine and Jilin Agricultural University, there are many kinds of free amino acids in ants, among which threonine, phenylalanine, valine, isoleucine, leucine, lysine, methionine and tryptophan are essential amino acids for human body
Top
What trace elements do ants contain
at present, there are 14 kinds of essential trace elements for human body, namely selenium, zinc, manganese, iron, cobalt, copper, iodine, molybdenum, chromium, nickel, tin, silicon, fluorine and vanadium
there are 28 kinds of trace elements such as calcium, iron, magnesium, phosphorus, manganese, zinc, iodine and copper in ants. The content of zinc is the most abundant

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.
