Mathematics computing power 2312

1.

computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second

in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow

computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value

therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world

unit of force

1 KH / S = 1000 hashes per second

1 MH / S = 1000000 hashes per second

1 GH / S = 1000000000 hashes per second

1 th / S = 100000000000 hashes per second

1 pH / S = 100000000000 hashes per second

1 eh / S = 100000000000 hashes per second

2. As a blockchain researcher, many new people often ask this question. In fact, there are two main ways to invest in bitcoin. The first is to buy bitcoin directly from the corresponding digital currency exchange; The second is to mine for bitcoin

first of all, mining is the main way to obtain bitcoin, but the current threshold of mining is relatively high. If you choose to mine by yourself, first you need to understand certain technology, then download the bitcoin client and mine by yourself according to the online bitcoin mining tutorial
however, in theory, bitcoin can still be mined with computers or graphics cards. However, e to the development of mining instry in recent years, the whole network computing power of bitcoin is extremely terrible (more than supercomputers), so if you want to mine with computers or graphics cards, you can't find bitcoin, If you want to dig bitcoin, you still need to buy mining machines. Now the better mainstream mining machines in the market have to be tens of thousands. Of course, there are cheap second-hand mining machines, but these second-hand mining machines are all obsolete ones, and the electricity cost of mining is relatively high

in addition to the second way of direct purchase, the digital currency exchange is a special place for bitcoin trading. If you want to own a bitcoin, you can buy it directly with money. However, it should be noted that there are many digital currency exchanges in the market at present. Many small exchanges are specialized in cutting users and eating customer losses for a living. Therefore, when choosing an exchange, it is better to focus on the head exchange. For example, Hufu, one of the head exchanges in China, I have been using it for nearly two years, and it is very stable and safe.

3. Take the free computing power jointly launched by the tenth power and computing earth, which mainly provides free computing power support for projects that need a large amount of computing power output. The computing power bank can provide idle computing power for personal devices around the world and provide computing power support for world-class scientific research projects, involving mathematics, physics, chemistry, life sciences, astronomy and other fields.

4. At present, the tenth power computing platform can provide customers with idle computing power of personal devices worldwide and provide computing power support for world-class scientific research projects, involving mathematics, physics, chemistry, life sciences, astronomy and other fields. So far, the computing power can reach 30p, which is equivalent to the computing power of tianhe-2, the world's fifth largest supercomputer, and can meet the needs of all computing power projects on the market.

5. Renren mine brand is older, the strength of investors is better, there are mines in the world, and the risk is greater than Xiaolu

6. Computing power (also known as hash rate) is a measure of bitcoin network processing power. That is, the speed of computing hash function output for computer (CPU). Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second

in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on the computer's random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is the so-called proof of work mechanism (POW)

recently, bitcoin's network computing power has entered the era of P computing power (1P = 1024t, 1t = 1024g, 1g = 1024m, 1m = 1024k). In the ever-increasing computing power environment, the arrival of P era means that bitcoin has entered a new stage of arms race

computing power is a measure of the total computing power of the unit that generates new blocks under certain network consumption. The single blockchain of each coin varies with the time required to generate a new transaction block.

On the front of the coin are printed "people's Bank of China", "1 yuan", Chinese phonetic alphabet "Yiyuan" and "2004" year number; The pattern on the back is children and the Chinese Zodiac elements, and "Jiashen" is printed below

in order to welcome the arrival of Jiashen year of the lunar calendar, the people's Bank of China announced on January 6, 2004 to issue a set of commemorative coins to celebrate the new year of the monkey. The front of the coin consists of Chinese and English characters of "1 yuan" and the year number of "people's Bank of China" and "2004" above the inner edge. On the back of it is a picture of a little boy wearing traditional Chinese clothes flying a "Kite" happily. Now the market price is about tens of yuan

10. The water consumption in April is 61 tons, and that in May is 58 tons. The average water consumption in two months is 59.5 tons. Generally, the water consumption is not decimal. We calculate it as 60 tons, and the figure on the water meter display at the end of June is about 547.
