Overseas official website of ant mining machinery

1.

It is reported that the performance of bm1385 chip is more than twice that of bm1384

The power supply scheme of S7 is similar to that of S5. The S5 + mode of dense chip arrangement is adopted, which makes the arrangement structure more compact. Under the same space, 60 chips are placed in S5 and 162 chips are placed in S7

The price of S7 is 1823 US dollars, equivalent to 11650 RMB yuan, and the delivery time is from September 21 to September 30. At the same time, the official announced the parameters of ant mining machine S7. The chip adopts bm1385, a 28nm fully customized chip independently developed by bitcontinental, with a computing power of 4.86t and a power consumption of 1201w. Ant miner S7 is the best miner with the best power consumption ratio so far, and the power per T is about 250W

official website is not open for sale at the moment. Users of early adopters can place their orders in overseas official website. The delivery address is 17% of the Chinese mainland tax and the purchase price is 13630 yuan. p>

2. At present, there are rental cloud computing power and mining machinery rental! Generally speaking, we should look at the official website, proceres and modes. And whether there is a mine! You should be talking about Xingyun mine, not Xingyun miner!

3. bitcoin can be understood as a stock, and mining machinery is the employee of the stock. Working for the stock, the stock can be bought and sold as well as transferred as money. When transferring money, users need to pay a service charge, just like bank transfer. The service charge is to pay the wages of the mining machine, so the mining machine has income. After receiving the service charge (BTC), the holder of the mining machine can take it to the exchange to sell it, which is equivalent to making money. Because of the evolution of the market over the years (omitting 10000 words here), now the income is very stable and high, so more and more people are engaged in mining. You can check more on the Internet and search today's miners. There are many articles suitable for Xiao to read.

Ant miner is the first cryptocurrency miner brand in the world with a market share of about 70%. The mining machine is developed by bitmainland and has a patent in mainland China. At the beginning, ant miner had only bitcoin miner. Later, its business expanded to other cryptocurrencies, such as Ethereum, dascoin, Leyte, Monroe, etc

ant mining machine adopts ASIC chip designed by bitcontinental, which is proced by TSMC. All chips are made of BM prefix. Each miner has three to four circuit boards, and there are dozens of chips on the circuit board. Therefore, each miner can only be used to mine one or more cryptocurrencies using the same algorithm

ant mining machine needs special mining software, and can not use third-party software. In addition, because of its high power, the ant miner also needs to be used with a special fire ox

The ant miner is often criticized as monopolizing the cryptocurrency mining instry e to its 70% market share, which goes against the purpose of cryptocurrency decentralization. Because Monroe was worried that the mining machinery would monopolize the mining market, Monroe announced to change the mining algorithm a few days after the launch of Monroe (X3 model) despite the opposition of Monroe community, so that all mining machinery could not be used to mine Monroe. Bitcontinent also encountered the failure of its first proct here

the ant miner will use a lot of electricity and proce a lot of waste heat in the process of operation. This leads to a large amount of electricity being consumed for mining or cooling, causing a lot of social criticism. Too much ant mining machine at the same time also led to fire and power failure, causing social inconvenience

5. Let's have a look. I know that graphene has high electric conctivity and high electric heating coefficient. It's easy to make procts by heating graphene heating film in 3 seconds

6. From the analysis of the announcement of 5.25 joint examination of Zhangzhou and Quanzhou in Fujian Province in 2019, it can be seen that the written examination paper of comprehensive posts in Fujian public institutions examination is "comprehensive basic knowledge", the total score of the written examination is 100 points, and all the questions are objective questions. The written examination covers basic theories of politics and economy, public administration, legal basis, professional ability, professional ethics, science and technology and humanities, and the situation of Fujian Province. In short, only one test paper is tested for comprehensive posts in Fujian public institutions. This test paper has both professional ability test and common sense test. And often high score examinees have a common feature, that is, everyone in the line test occupation ability test level is quite the case, get common sense to face the opportunity

however, the difficulty of getting high marks in common sense lies in a contradiction. First of all, the common sense examination covers a wide range of subjects, including political theory (current politics, Marxist philosophy, theory of socialism with Chinese characteristics), economic theory, public management, legal basis (jurisprudence, constitution, criminal law, administrative law, civil law and other minor laws), morality, science and technology, humanities, and the situation of Fujian Province. Such a detailed count contains 14 sub subjects. From the announcement to the written examination time about one month before and after the preparation time, this is very hasty. Therefore, there is a contradiction between many subjects and short preparation time. In order to solve this contradiction, we should not grasp the eyebrows and moustaches when preparing for the written examination. Because it is not only time-consuming, but also not proficient, so it is difficult to break through the high score in the exam and become a lucky person. Therefore, we need to make a further in-depth analysis combined with the examination questions, and grasp the key subjects and characteristics of the written examination in Fujian public institutions, so as to achieve the maximum learning results in a limited time

the key subjects of common sense examination are politics, law and economy, followed by public management and official documents, and finally morality, science and technology, humanities and the situation of Fujian Province. From the distribution of questions, politics accounts for about 50%, law accounts for about 27%, economy accounts for about 17%, and public administration and official documents account for about 3% respectively. The possibility of examining morality, science and technology, humanities and the situation of Fujian Province is very small

the characteristics of each subject of common sense are also worth talking about. First, in political subjects: the time range of current politics is generally three months before the examination, for example, the year of the anniversary, the names of famous people. Marxist philosophy and the theory of socialism with Chinese characteristics are often combined with the current hot topics, such as garbage classification, supply side structural reform, Rural Revitalization Strategy and so on. The difficulty of the examination is similar to that of the college entrance examination, so we need to firmly grasp the theoretical knowledge and have a certain reading ability. Second, in legal subjects, legal theory, constitution and administrative law are often memorized, while criminal law and civil law are combined with legal cases for understanding. Third, the difficulty of the examination of economic knowledge is close to that of the college entrance examination. Combined with the current economic hot issues, such as: sharing economy, RMB joining the SDR currency basket, digital currency and legal digital currency, candidates are required to have a certain knowledge of economic terms, so that these problems can be solved. Fourth, the topic of public management is often combined with the current function reform of the party and state institutions. Fifthly, official documents have always been the test of memorization, which is less difficult. Other subjects will not be repeated.

7. New or old, the old need to do in the inspection, contract invoice box single can be reported to expect fine

8. Generally speaking, the domestic customs declaration fee for imported ant mining machine is not much, and there is no problem with the data of goods arriving at the port. We need to confirm the 3C problem in advance, declare to the customs, pay taxes, and release. The focus is on 3C
the import of ant mining machine mainly includes S9, L3 +, T9, S7 and other types of mining machine
