The positive impact of blockchain on government work

1. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

2. Chongqing jinwowo analyzes the impact of blockchain technology on the instry: blockchain will determine the relationship between people and all the Internet including artificial intelligence. The change of this relationship will have a subversive impact on the mainstream Internet business model and create a new era of decentralization.

3. Blockchain technology is a new development of Internet technology and modern information technology. It plays an important role in China's real economy and supply side structural reform. Promote the R & D and application of blockchain technology, deeply integrate with the real economy, and create an advanced manufacturing instry. It can realize the high-quality development of China's economy and is an important driving force for the construction of a modern economic system.

4. What is blockchain technology

before discussing how to apply blockchain in daily life, let's talk about what blockchain is and how it works

blockchain is an open distributed database, which is essentially a computer file used to store information (data)

the name of blockchain comes from its structural characteristics: the file is composed of data blocks, and each block is linked to the previous block to form a chain. Each block contains data, such as transaction records and records when the block was edited or created. Information (data) is stamped with time stamp, which is the origin of blockchain

it is crucial that, unlike centralized databases owned by companies or government agencies, blockchain is not controlled by any person or entity, and data is completely copied (distributed) on multiple computers

because it is a decentralized way to store and access data, it becomes extremely secure. Different from the centralized database, the attacker does not have a single entry point, so the data security is more guaranteed<

in addition to the two characteristics of decentralization and security, blockchain has become a leading technology which is different from other technologies:

tamperability: once entering the blockchain, any information can not be changed, even the administrator can not modify this information. It makes blockchain easy to audit

accessible: all nodes in the network can easily access information

no third party: blockchain can help point-to-point transactions, so whether you are trading or exchanging funds, you do not need the approval of a third party. Blockchain itself is a platform

the impact of blockchain technology

first, the open and tamperable nature of blockchain technology makes it possible to decentralize the trust mechanism. It has the potential to change the financial infrastructure. Various financial assets, such as equity, bonds, bills, warehouse receipts and fund shares, can be integrated into the blockchain ledger to become digital assets on the blockchain, which can be stored, transferred and used in the blockchain Deal. It has a broad application prospect in the financial field. For example, it has typical applications in cross-border payment, insurance claims, securities trading, bills, etc

Second, the current Internet of things ecosystem relies on the centralized network management architecture, and all devices are connected through the cloud server. With the expansion of the network scale, the infrastructure and maintenance of centralized cloud servers, large servers and network equipment will occupy a high cost

in the decentralized Internet of things, blockchain is a framework to promote transaction processing and cooperation among interactive devices, and each device on the network can operate as an independent and micro business entity< Third, public service is a factor to promote economic growth and social progress. The supply of public service has an important impact on various subjects, systems, cultures, attitudes and behaviors in the process of political, economic and social development. The traditional notarization relies on the government, and the limited data dimension and the historical data information chain that has not been established often lead to the government and schools unable to obtain complete and effective information. Using blockchain, tamper proof can be established. In the fields of digital rights, intellectual property rights, certificates and public welfare, new authentication mechanisms can be established to improve the management level of public services.

5. As the two major trends in the development of the Internet, blockchain and big data not only have a strong driving force for the rapid development of enterprises, but also play a great positive role in reshaping the social integrity system

through the blockchain, jinwowo Group believes that the blockchain can not only trace the source of every commodity on the platform, ensure the quality of commodities, but also record the real behavior of every user on the platform, so as to enhance the integrity constraints of online behavior; Moreover, these behavior data can be reasonably and legally applied through the characteristics of blockchain itself.

6. Blockchain is like a "double-edged sword" for the government and the public sector: on the one hand, the characteristics of the distrust of blockchain bring challenges to the government, banks and other "trust intermediaries"; On the other hand, the underlying philosophy of distributed consensus, open source, transparency and social cooperation of blockchain technology represented by chainnova will bring more obvious advantages to the government and public sectors. It is necessary for the government to participate in the development and supervision of blockchain. It is necessary to understand the potential of this technology as soon as possible, introce innovative solutions, and provide better public services for the public.

7. The application of blockchain to government affairs can effectively promote the transformation of government roles and functions, promote the flattening of government organizational structure, transparency of governance and service process, improve government innovation performance, improve government data security, and help to build an intelligent and trustworthy government. At present, China is vigorously promoting the application of blockchain government services. The public platform of SMIC blockchain is a good one, which has promoted tens of thousands of enterprises in Changsha.

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

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
