2. Because indivial mining is difficult to meet the demand, the global computing power is increasing, and it is difficult for a single device or a small amount of computing power to dig bitcoin again. It is also a combination of a large number of mining machines to form a mine pool. The computing power of the mine pool is very powerful, and it can also ensure that virtual currency can be g more quickly. So how can the mine pool dig? Let's have a look
how to mine a mine pool
the location of a mine pool is also very particular. It's not that a mine pool can be built anywhere, but it needs early-stage capital investment. A mine pool is to combine a single mining machine together. Because of the collection of many miners' computing power, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher. The mine pool will distribute rewards according to the contribution value of each equipment
there are many mines all over the world, and the scale of each mine varies from big to small. Generally, small mines no longer have great advantages. Large mines have many miners for mining. For each miner, he can join any mine or join multiple mines at the same time, The first task of the mine pool is to distribute the income to the miners
(1) PPLNs method
this method gathers the shares g by all miners together. Whenever a certain amount of shares is accumulated (generally 30 million shares), the mine pool will allocate the profits of the previous stage to the miners according to the proportion of contribution
in this way, the income of miners depends entirely on the time needed to dig 30 million shares in the mine pool. If you are lucky, you can dig them in a short time, then the income of miners will be more, otherwise it will be less. In return, the pool charges a 3% tax
(2) PPS mode
for users, the income of this mode is relatively stable
the profit mainly depends on the miner's mining speed. As long as the mining speed is stable, the corresponding profit can be obtained, and the profit is real-time, that is, the mine pool will pay the profit for the miner while the miner is running
obviously, every time a block is calculated, the mine pool has paid for all the miners. If the block fails in the subsequent confirmation link, all the losses will be paid by the pool operator. Therefore, this method reces the risk of the miners, but transfers the risk to the pool operator
therefore, usually the ore pool can charge a handling fee to make up for the possible losses caused by these risks. In this mode, the tax of the ore pool is 7.5%
the above is about how to mine. The difficulty of mining has greatly increased, but the mining army is expanding. If the basic equipment does not meet the standard, it will be difficult to gain in the mining instry, because the value of the virtual currency may not be equal to the price of an equipment, and many miners are not just digging bitcoin, Instead, we choose other virtual currencies to mine.

3. Bitcoin is the most popular virtual internet currency in the world. It can also buy a lot of things now. This kind of virtual currency can be obtained through the function of mining machine.? So how to get bitcoin? First of all, your computer should be installed with the latest version of bitcoin client. After opening the client, it will automatically download all the transaction information data on the network to the local. Depending on the network speed, this process may take several hours. At this time, your account balance is 0, you can ask your friends to send you some coins, but there are two more feasible ways: one is to do business, the other is to do mining. Many domestic users choose the second way, that is to do mining. More and more people are willing to work as miners themselves and let their computers proce bitcoin! It sounds tempting - just one computer can make money! The bitcoin g up by yourself as a miner can be converted into real RMB at bitcoin China trading platform! Now the threshold is higher than before. It's better to need professional computers. The difficulty of bitcoin mining is directly proportional to the amount of money that has been mined. The more difficult it is to mine, the more difficult it will be. After 20 million bitcoins are mined out in 2030, the remaining 1 million bitcoins will probably take decades to be mined out. At present, if the computer is on 24 hours, it will take about three months to dig a bitcoin.
4.
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data
mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
5. Cloud Computing: one of the three carriages enabling the future
cloud computing, big data and artificial intelligence are known as the three carriages driving the future and enabling the real economy! At present, 48 of fortune's top 50 companies have publicly announced their cloud deployment plans, and the IT departments of many of them have widely used cloud services
Adobe's market value has increased by 10 times in the past nine years when it transformed into SaaS service; In the nine years since its listing, the market value of salesforce has increased by 30 times. Microsoft's revenue in the third quarter was US $30.6 billion, and cloud computing became the biggest contributor to the revenue growth of Microsoft's business. The revenue of intelligent cloud services sector reached US $9.7 billion, an increase of 22%<
according to the data report given by canalys, a research institution, the global cloud computing market in 2018 exceeded US $80 billion, reaching US $80.4 billion, with a year-on-year growth of 46.5%. In 2018, AWS had a revenue of US $25.4 billion, accounting for 31.7% of the market share, while Microsoft azure ranked second in the market, with an annual revenue of US $13.5 billion and a market share of 16.8%. In addition, according to the latest report released by Bain company, the size of the global cloud computing market is expected to rise to US $390 billion by 2020, with a compound annual growth rate (CAGR) of 17%, Forbes Online reported. The global cloud computing market scale accounts for 0.37% of GDP, while the domestic cloud computing market scale accounts for only 0.13% of GDP in the same period
China has a consumer Internet giant with the same strength as the United States, but it is several times different from the instrial Internet. With the disappearance of Internet demographic dividend, the dividend of domestic 2C consumer Internet users has subsided, and 2b instrial Internet is on its way, the troika of cloud computing, big data and artificial intelligence, It will witness the development of instrial Internet and usher in its own golden development. Instrial Internet acceleration, technology empowerment, China's 100 billion cloud computing market is waiting for its cultivators<
Cloud Computing: Top 10 development trends
here is a list of top 10 forecasts of the development trend of cloud computing instry in 2019 made by practitioners, analysts and enterprise decision-makers in the cloud computing instry for your reference<
participating in IDC circle: Top Ten Trends of cloud computing in 2019: cloud has become the main way to obtain artificial intelligence
1. Extensive use of intelligent decision-making has become an advanced symbol of enterprises
artificial intelligence has stepped out of the "entertainment world" and started to widely assist human decision-making in enterprise operation
in the future, whether an enterprise is advanced or not, one of the main measurement indicators is the proportion of intelligent assistance employees (not only serving executives) to make decisions. Cloud is no longer an issue discussed by technology circle, but more concerned by enterprise decision-makers
it is more urgent for enterprises to use artificial intelligence and other technologies for business innovation than ever before. At the same time, cloud based intelligent business will also trigger organizational change
2. Enterprises will graally give up the self built it infrastructure and move to the public cloud, resulting in "cloud based native enterprises"
the infrastructure of Netflix, an American video website, has been relocated to Amazon AWS. A small number of Chinese enterprises have realized such overall cloud relocation in 2018, and it is expected that a large number of cases of such overall cloud relocation will emerge in 2019
the cloud of means of proction means the opening of a new era
3. Cloud has become the most important path for enterprises to acquire AI
cloud naturally solves the unification of enterprise data and technology, and constitutes the most important path for enterprises to acquire AI capability< At present, public cloud platform has become the most important channel for customers to obtain AI services at low cost
in the business field, artificial intelligence technology that has been verified by cloud service providers' own business is favored by enterprise decision makers<
4. Hardware cloud service providers graally bid farewell to the public cloud market
in 2018, the traditional hardware start-ups encountered collective acclimatization in the era of public cloud
IBM's share of cloud computing has declined. Before that, HP, Cisco, Fujitsu and other enterprises had setbacks in entering the public cloud market with the help of open source openstack technology. The analysis shows that the hardware manufacturers' failure in the public cloud market lies in their failure to understand the nature of cloud computing
the essence of cloud computing is not a "computer" but a service. In addition, such enterprises are almost perfectly wrong with the Internet era. As a result, the hardware genes of the above-mentioned manufacturers are so powerful and the existing businesses are so successful that they are faced with the "innovator's dilemma"
5. The public cloud market is further concentrated
according to the statistics of authoritative market research institutions Gartner and IDC, four manufacturers, including Amazon AWS, Microsoft azure, Alibaba cloud and Google cloud, have become the leading forces in the global public cloud market, and their revenue growth rates are far faster than the average growth of the instry
Goldman Sachs, a Wall Street investment bank, predicts that Amazon, Microsoft, Alibaba and other giants will occupy about 84% of the core cloud computing market in 2019. These companies are significantly ahead of their competitors in talent, technology, operation, service, capital, ecology and other aspects. It can be predicted that the global cloud computing market concentration will be further improved in 2019, and will be more significant in the next few years
6. Enterprises prefer full stack solutions
in the past year, with the accelerated penetration of intelligent technology in the business field, many enterprises have realized intellectualization in some business links
however, more and more CEOs prefer comprehensive solutions than artificial intelligence technology to enhance a certain business or link. This kind of solution can not only realize the data of the company's business, but also provide a set of verified intelligent tools to help enterprises realize intelligent decision-making
in 2019, more comprehensive intelligent solutions will continue to appear and be welcomed by the market
7. Enterprises embrace cloud computing for security
in the past, security has become an obstacle
when many enterprises choose whether to go to the cloud, the most important concern is security, not only for their own information security, but also for the stability of business systems. However, with the digital transformation of the whole society, all kinds of business operations of enterprises will inevitably touch the Internet. In order to seek business security, they begin to become the driving factors for enterprises to actively go to the cloud
cloud computing manufacturers have a strong security team to serve too many types of customers, which can enable enterprises to obtain a strong security protection capability at low cost, which has changed the investment habits of enterprises in security in the past< After more than 10 years of development, cloud computing technology has graally matured, and the enterprise's acceptance of cloud computing is also further improved
as cloud computing can bring obvious utility to enterprise IT operation and business innovation, cloud computing has become the norm of enterprises
in 2019, the whole society will put more and more budget into the field of cloud computing, which will further enhance the proportion of cloud computing in the overall it expenditure. Goldman Sachs, a Wall Street investment bank, predicts that the market penetration rate of cloud computing will exceed 10% for the first time in 2019, and it will jump to 15% by 2021. This means that cloud computing will further erode enterprise IT spending and enhance its influence in the IT market< M & A activities in cloud computing instry will be more frequent
in 2018, there are many large-scale M & A transactions in the field of cloud computing, which are divided into different fields such as chip, security, artificial intelligence, developer community, cloud solutions, etc
in order to maintain the rapid growth, the mainstream cloud computing manufacturers need to launch more high value-added procts or services, and constantly expand the scale of paying customer groups. Mergers and acquisitions have become a means to achieve rapid results.

6. First of all, the "mine" of mining is in fact a virtual currency such as "bitcoin" (this kind of virtual currency is actually a string of encrypted characters. Due to its very high scarcity, "relative value" is very high. The reason why we use "relative" is that for those who accept it, it is money. For those who do not accept it, it is a string of characters!)
mining is actually using a special customized computer to run a set of special algorithms to decrypt the encryption algorithm of virtual currency For example, this currency has a series of codes. People "guess" the code through the algorithm. If they guess all the codes correctly, they can get a complete virtual currency. If they guess one point correctly, they can get a part of it, such as "0.00035637 bitcoins". Yes, virtual currency can be divided. It is not possible to dig a complete bitcoin at one time. The bitcoin g is a string of characters.)
the reason for mining with graphics card is that the algorithm of decrypting bitcoin is actually very simple, which is not a high-level operation, but it has a lot of amount, and the graphics chip is more suitable for this than the CPU chip For example, 1 + 1 =? 2+2= This kind of algorithm seems simple to you, but if I tell you this kind of simple algorithm, there are 100 million in total?! Would you like to try to figure it out? I believe you can figure it out, but it's just a long time)
(CPU chips and graphics chips have a huge number of transistors, which are responsible for computing. The difference is that the transistors of CPU chips are divided into many parts, which can deal with all kinds of task instructions. When running simple operations, only a part of the transistors are working, The others are on standby, because other transistors are not responsible for this task. They can calculate, even if they are relatively slow, but they will still consume the same power, resulting in a low cost-effectiveness ratio.
(graphics chips are different. In fact, most of their work is "crazy rendering triangles". What's a crazy method? Render 1 billion triangles in one second!!! This work is relatively simple, but the amount is very large, and there is a high requirement for the speed of "rendering", so the graphics chip can make its transistors all move when it is designed, so as to achieve the purpose of "rendering" more triangles in the shortest time! This happens to be very similar to the process of decrypting bitcoin, so most of them use graphics cards to mine. This doesn't mean that CPU can't mine. People can mine with their heads. Do you believe it? It's just very slow, and the value of the bitcoin is not enough to pay for your electricity and meals)
mining can't "lie down and make money", because a qualified miner's price ranges from tens of thousands to hundreds of thousands according to its computing power. Because it consumes a lot of electricity, the cost of mining is not only to buy a miner, but also to include the electricity! Moreover, the mining machine needs good heat dissipation and daily maintenance to extend the life of the hardware as much as possible, so if you dig the mine, you will not have much leisure. In addition, the number of virtual currencies is limited, it is more and more difficult to dig, and the stability of the value is poor. Maybe you invest 10 million yuan to build a mine, and a wave of collapse will occur. You have been frozen for 10 million minutes

7.
I recommend two: ant G2 graphics card miner, panda B3 plus graphics card miner
ant G2 graphics card miner is used to mark panda's B3 plus graphics card miner. In terms of computing power, they are almost the same. On the one hand, they use the vest card, and on the other hand, they use the rx470 without the vest, both at 220mh / s
8. According to the current calculation, it will take at least 650 days to dig out one under the top configuration. Rx588 is estimated to take 1000 days anyway.
9. Binary coded decimal number is called BCD code for short. In this method, the combination of 4-bit binary code is used to represent the 10 number symbols of decimal number: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. There are 16 combinations of 4-bit binary numbers. In principle, 10 of them can be selected as codes, representing the 10 decimal symbols of 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The most commonly used BCD code is called 8421BCD code. 8.4.2.1 is the bit value of 4-bit binary respectively. Click here to give the corresponding relation table of decimal number and 8421BCD code< Conversion between BCD code and decimal number
conversion between BCD code and decimal number is intuitive, and mutual conversion is also very simple. Convert decimal number 75.4 to BCD code, for example:
75.4 = (0111 (0101.0100) BCD if convert BCD code 1000 0101.0101 to decimal number, for example: (1000 0101.0101) BCD = 85.5
note: the number represented by the same 8-bit binary code, When we think that it represents a binary number and that it represents a binary coded decimal number, the value is not the same
for example: 00011000, when it is regarded as a binary number, its value is 24; But as a 2-bit BCD code, its value is 18< Another example is 00011100. If we regard it as a binary number, its value is 28, but it can't be regarded as BCD code, because in 8421BCD code, it is an illegal code.
2. BCD code format
there are two formats of BCD code in computer, that is, separate BCD code and combine BCD code
the so-called separated BCD code is to use the lower four bits of a byte to represent one bit of a decimal number. For example, the storage format of number 82 is:
\_ 1 0 0 0 _ _ _ _ 0 0 1 0 where_ Represents an unrelated value
combined BCD code is to store two decimal numbers in a byte. For example 82, the storage format is 1000 010
3. Addition and subtraction operation of BCD code
because the code represents each decimal number with a group of 4-bit binary numbers, if the BCD code is directly sent to the computer for operation,
the computer always treats the number as a binary number, So the results can go wrong. Example: using BCD code to find 38 + 49
the solution is to use & quot; Add 6 correction, which is called BCD adjustment. That is to say, the result of binary addition is modified to that of BCD code addition. When two two bit BCD numbers are added, the result of binary addition is modified by correction rules. Correction rules:
(1) if the result of the addition of any two corresponding BCD numbers has no carry to the higher bit, if the result is less than or equal to 9, then the BCD number does not need to be corrected; If the result is greater than 9 and less than 16, the bit is corrected by adding 6
(2) if the result of the addition of any two corresponding BCD numbers has a carry to the higher bit (that is, the result is greater than or equal to 16), the bit is corrected by adding 6.
(3) when the result of the lower correction makes the high bit greater than 9, the high bit is corrected by adding 6
an example is given to verify the correctness of the above rules
using BCD code to find 35 + 21, BCD code to find 25 + 37, BCD code to find 38 + 49, BCD code to find 42 + 95; Borrow one for sixteen; And & quot; Borrow one for ten; The difference between the two results will be 6 more than the correct result; Minus 6 correction method & quot; When two BCD codes are added and subtracted, the binary addition and subtraction instructions are used first, and then the BCD adjustment instructions are used to adjust the results, and the correct decimal operation results can be obtained. In fact, there are not only adjustment instructions for combining BCD numbers, but also adjustment instructions for separating BCD numbers. In addition, the addition and subtraction operation of BCD code can also be transformed into binary number by the program before operation, then the binary number can be processed by the computer, and then the binary number result can be converted into BCD code by the program after operation.
