Blockchain will be commercialized
the second is that only mature technology is not enough. In order to realize a large number of DAPP and commercial applications on the blockchain, we must be prepared on one hand: that is, the digital currency that can be used as payment tool, exchange medium, value measure and value storage. Xiao Feng said that everyone thinks that bitcoin is a payment system, but the real bitcoin can not meet our demand for payment because its currency value fluctuates too much
for example, he said that a mall sold a bottle of water and accepted bitcoin payment. When he got up the next morning, he found that 20% of the value was gone. So it can't be accepted. After the Japanese parliament made it clear that bitcoin could be used as a payment tool, some Japanese businesses announced that they would accept bitcoin payment. But later found that it caused a lot of trouble for the stability of the company's balance sheet. Your balance sheet is unstable, up or down. This not only affects the value of the things sold, but also affects the credit evaluation of enterprises and the services provided by banks to companies
the third condition is the construction of laws and regulations and supervision system. The digital economy on the blockchain must obtain legal protection and comply with the law. Xiao Feng stressed that there can be no decentralization in this regard
the differences between blockchain and Internet are discussed. He believes that the core difference between the two is that the Internet is a centralized trust mechanism, while the blockchain is a decentralized trust mechanism, and there is no need to trust a third party
the second core difference between the Internet and blockchain is the incentive mechanism, not the digital currency or the ability to issue currency. Economics has been discussing incentive incompatibility. Under the company system and on the Internet, the incompatibility of incentive mechanism has not been solved. However, in the decentralized blockchain, the blockchain achieves complete incentive compatibility. Without shareholders, board of directors and employees, the conflicts of interest between these roles will not happen again.
the blockchain instry is on the eve of the application outbreak
as a kind of underlying technology, with the support of policy direction, blockchain is attracting more and more exploration of application landing. At the recent 2019 future business ecological link conference, Zhu Youping, deputy secretary of the general Party branch of China economic network management center of the state information center, pointed out that after 11 years of trial and error, the technology of blockchain has basically been commercially available, and the instry is now on the eve of application explosion
Wu Xiaochuan, a senior expert in Zhongan technology's blockchain development, told the 21st century business reporter that the biggest difficulty in the current blockchain landing instry is how to map the physical world and the blockchain world one by one, which needs multi-disciplinary joint efforts to solve. Internet of things technology is an important part of it. With the blessing of 5g, cloud computing and other technologies, it will bring more complement and support to the implementation and application of blockchain technology in the futureaccording to the prediction of tractica, the analysis organization, the global enterprise blockchain market will reach US $20.3 billion by 2025
key node of technology and standard promotion
compared with other underlying technologies, blockchain has also experienced a relatively tortuous development process, and there is still a way to go in terms of integration with multiple technologies and setting of its own standards
Zhang Xiaojun, head of Huawei's blockchain, pointed out in his speech at the conference that today's blockchain technology is more like the development stage of the Internet from 2002 to 2003. If the relevant standards of blockchain can be mature in 2020, including cross chain standards, storage standards and standard data format storage, large-scale commercial use will be accelerated in 2021
China's blockchain instry is still in its infancy, but with the continuous support of national policies, the continuous progress of instry technology and the increasing demand of downstream applications, China's blockchain instry is expected to continue to maintain high-speed growth. In 2011, the market scale of China's blockchain instry was less than 6 million yuan. By 2018, the market scale of China's blockchain instry has grown to 67 million yuan, maintaining a rapid growth rate of more than 80%. It is estimated that in 2022, driven by policy support and downstream demand, the market scale of China's blockchain instry is expected to exceed 450 million yuan
market size statistics and growth forecast of China's blockchain instry from 2015 to 2022 Zhu Youping pointed out to the reporter of the 21st century economic report that with the technical blessing of 5g and even future quantum computing, these weaknesses will be quickly made up

Meanwhile, foresight Instry Research Institute also provides instrial big data, instrial planning, instrial declaration, instrial park planning, instrial investment promotion and other solutions
in the future, it will be applied in all walks of life.
The mechanism of mineral refresh in the original God is 72 hours (3 days) refresh. Four people form a team to dig the mine, and rotate every day. They can also dig all the mines of four people at one time, once every 4 days. But they still have to go to the blacksmith's place to make iron every day. Crystal ore is refreshed every 3 days, white iron ore is refreshed every 2 days, and iron ore is refreshed every 1 day
for the mining mechanism, there is no upper limit (or the upper limit is very high) for mining every day after the public beta, but the weapon experience materials obtained by forging in different ways at the blacksmith every day have a common upper limit of 300000 (equivalent to 120 crystal minerals, except weapons), which means that iron ore, white iron ore and crystal ore share the upper limit
extended data:
it is suggested that three people should take turns to dig one person's world's mine a day; Suppose we dig a on Monday; Dig B on Tuesday; Dig C on Wednesday; Thursday dig a; By analogy, there will be mines every day. Similarly, Xiaobian suggests that the resources with a brush of 48 hours should be mined once every three days
in the game of the original God, the more advanced the ore, the longer the refresh time. For example, for low-grade ore such as iron ore, the refresh rule is once a day; Pyrite, yeposhi and perlite are refreshed every two days, while crystal ores are refreshed every three days
2. Plutonium can supplement life support devices, mining beams and driver fuel. It can save a little more.
3. Mine the low-yield minerals on the planet. Dig too much at a time The patrolmen will attack you. So half of the patrolmen will come to scan you. Stop mining at once
4. As long as they enter the house, the patrolmen who attack you will retreat. So there is a rare mine in need. As long as there is a room nearby, they can dig at ease. If the patrolmen attack, they just run into the house. It's the same when they destroy the door of the house. As long as they break the door quickly and rush into the house, the patrolmen will leave. But they can't The house that uses weapons looks useful. For example, the drop mole should not hide from the patrolman
5. The drop mole points on the planet. A drop mole can spend money to increase the space of a suit. I currently drive to 26 spaces. I don't know if the suit is full of 30 spaces
6. Abandoned spaceships can be found on the planet. But if they are better than the existing ones, please pay attention to them before changing them Go. Another thing is that the abandoned spaceship needs to be repaired. Pay attention before changing the spaceship. Otherwise, you can't fly after changing the spaceship (but your original spaceship will be left nearby after changing the ship. You can change it back first)
7. When the pulse moves, you will be caught by pirates. So it's ok if you don't turn on the pulse
8. The NPC spaceship in the space station and the trade station can interact. Yes If you find the place you are going to, how to keep increasing and decreasing the distance from time. It means that the place is on the other side of the planet, so you are flying out of the atmosphere and moving. You can accurately find more relevant content, which can be searched:

in order to implement blockchain technology from concept to commercial application, help more small and medium-sized enterprises build big data advantages, and help users trace procts and data, Chongqing jinwowo network technology group, together with member of computer forensics expert committee of Chinese society of electronics, initiator of blockchain special committee (Preparatory) of Chinese society of electronics in December 2017 Li Lizhong, chief scientist of jinwowo network technology group, has set up a blockchain research center in Hangzhou, which is dedicated to providing big data services for blockchain business applications to small and medium-sized enterprises.
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 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
