1. computing power refers to computing power. 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", Unit is written as hash / s, which is the so-called workload proof mechanism pow (proof

What does 1p mean
first of all, 1p computing power is equivalent to about 1.05 million g, which means that if you have 1g computing power of the whole network, you can get almost 1.05 million of bitcoin output of the whole network. According to the output of 3800 bitcoins per day, we can see that the daily income of 1g of computing power has dropped to 0.0036 bitcoins, which is about 2.7 yuan according to the current market price. If the electricity cost and mining machinery hardware cost are included, the profit is almost gone
secondly, 1p's whole network computing power seems amazing, but in fact, in a year's time, you will think it's just a pediatrics, because cointera will launch 2p miner in December, and bitmine will launch 4P miner in March next year. If these companies are not put in biochemical weapons by Syria, it should be expected that bitcoin's whole network computing power will reach more than 10p in a year's time, By then, 1g of computing power will only be able to dig 0.00036 bitcoins a day.

The types of chips that provide computing power for AI include GPU, FPGA and ASIC
GPU is a kind of microprocessor specialized in image operation on personal computers, workstations, game machines and some mobile devices (such as tablet computers, smart phones, etc.). It is similar to Cu, except that GPU is designed to perform complex mathematical and geometric calculations, which are necessary for graphics rendering
FPGA can complete any digital device function chip, even high-performance CPU can be implemented with FPGA. In 2015, Intel acquired the FPGA long alter head with us $16.1 billion. One of its purposes is to focus on the development of FPGA's special computing power in the field of artificial intelligence in the future
ASIC refers to the integrated circuits designed and manufactured according to the requirements of specific users or the needs of specific electronic systems. Strictly speaking, ASIC is a special chip, which is different from the traditional general chip. It's a chip specially designed for a specific need. The TPU that Google recently exposed for AI deep learning computing is also an ASIC
extended data:
chips are also called integrated circuits. According to different functions, they can be divided into many kinds, including those responsible for power supply voltage output control, audio and video processing, and complex operation processing. The algorithm can only run with the help of chips, and because each chip has different computing power in different scenarios, the processing speed and energy consumption of the algorithm are also different. Today, with the rapid development of the artificial intelligence market, people are looking for chips that can make the deep learning algorithm perform faster and with lower energy consumption
5. Like jiajiabao, play customer cloud and so on, they all have their own advantages in terms of function.
6. Bitcoin, in short, is an internationally recognized virtual currency. In some foreign countries, bitcoin can be used to trade; In China, it was also announced a while ago that bitcoin withdrawal might be tried out
bitcoin will be released on the Internet regularly to mine. To put it bluntly, it is the process that people use computer hardware to calculate the location of bitcoin and obtain it
mining is definitely the first professional mining machine. Many new children's shoes will choose to mine with graphics card. However, mining with graphics card is just like doing a professional job with "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.

7. There are many reasons for the low computing power of S7 bitcoin
1. It may be the problem of temperature. Low or high temperature will affect the calculation power of the miner
2. There are problems in the miner itself, which lead to abnormal calculation force
3. The aging of mining machine leads to the decrease of calculation power, and the calculation power of second-hand mining machine is relatively the first
bitcoin, Leyte coin, sand coin and all the mining machines that need mining are like this.

8. The strength of the company is very big, not bad
9. "A lot of scripts" may not be the script of the button wizard, right? Is it an offline script? Is it a script for offline plug-ins?
10. The current calculation method of electricity charge is to implement the single system of electricity charge, that is, to determine the electricity charge according to the proct of your electricity consumption and your electricity unit price
with the increase of electricity consumption, the step-by-step electricity price is a charging method of implementing different electricity prices at a certain stage
the specific contents are as follows:
the first step is the base power, which has less power and lower electricity price
in the second step, the electricity quantity is higher and the electricity price is higher
the third step has more electricity and higher electricity price
with the growth of household electricity consumption, the hourly electricity price per kilowatt increases step by step. The energy efficiency can be improved by implementing the step-by-step increasing electricity price. By segmenting electricity, we can achieve differential pricing in market segments and improve power efficiency. And it can subsidize low-income residents. Because this kind of electricity price policy takes care of the electricity demand of low-income people to maintain the minimum living standard, it is also commonly known as "poor people's electricity price"
for example, Zhejiang, Fujian and Sichuan provinces have implemented step-by-step tariff for residential electricity. Taking Zhejiang Province as an example, the electricity price of residents in Zhejiang Province is divided into three "ladder",
the electricity price within 50 degrees of monthly electricity consumption is 0.538 yuan / degree, of which the peak electricity price is 0.568 yuan / degree and the valley electricity price is 0.288 yuan / degree
for the monthly electricity consumption between 51 and 200 kwh, the electricity price is increased by 0.03 yuan / kWh to 0.568 yuan / kWh, of which the peak electricity price is 0.598 yuan / kWh and the valley electricity price is 0.318 yuan / kWh
if the monthly electricity consumption exceeds 200 kwh, the electricity price is 0.10 yuan higher than the basic electricity price, that is, 0.638 yuan / kWh, of which the peak electricity price is 0.668 yuan / kWh and the valley electricity price is 0.388 yuan / kWh
when the total peak valley electricity consumption exceeds 50 degrees, the excess electricity will be charged according to the "second step" price, increasing in turn.
