1803 calculation power

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. Mining is definitely the first professional mining machine. Many new children's shoes will choose to use the graphics card to mine, but the graphics card mining is just like doing a professional job with the "magic oil", but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.

3. This is definitely a loss.
recently, I saw a test that the rtx3070 notebook only earns 1.2 yuan an hour.
1050ti computing power is less than 1 / 4 of 3070, which is about 24%
power consumption is 35% of 3070.
energy consumption is not cost-effective. One hour's income is definitely less than 1 yuan, except for the electricity charge. Once the loss of notebook is eliminated, it is definitely a loss

4. 1. Mine card generally needs the specified driver version
2. The 382.33 384.76 384.96 driver installed on the official website can't work, only the 382.53 driver can work normally
3. If the driver of this version can not be used normally, you need to contact the official technician to provide the driver file for re installation.

5. Maybe the machine you bought is not very good

6. Computing power will fall, but if the technology is relatively stable, most of the miners with qualified operation and maintenance ability will recover within the specified time after occasional loss of computing power, so as to avoid huge punishment. If a large number of confiscated pledged currencies are not recovered within the specified time, it means that the technology of the manufacturer is not only unstable, but also the operation and maintenance ability is extremely poor. We have to choose carefully.

7. Because filecoin & IPFs punishes the loss of computing power for more than 24 hours and confiscates all the pledged and locked positions for more than 14 days, it is particularly important to note that if a node managed by a manufacturer is fined and confiscated a large number of pledged currencies e to the loss of computing power, it is absolutely not allowed to choose!

8. Occasionally, small-scale computing power loss is inevitable. However, if a vendor's node frequently loses computing power (for example, once a few days), it means that the technical solution is not stable enough and needs to be carefully selected!
