The calculation power of easy miner is always 0

1. 1050ti has a bit more than 12 computing power by default, which has nothing to do with software. If you want to improve the computing power, you need to download a micro star small aircraft software to overclock. Samsung video memory can overclock to about 15.5

2. 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
of
work)
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.

3. There must be damage. First of all, only a card can be used for mining, and N card is boring for mining.
secondly, the computer needs to be running all the time and can't be turned off for mining, which requires a lot of computer. It is harmful for each part to do a lot of calculation for a long time, and it also requires high power supply for the computer
mining can't be powered off, and it needs to be recalculated after power off. Graphics card long time to do a lot of calculations will lead to greatly shorten the life of the graphics card, so their own home, do not recommend mining, mining is not as expensive as electricity

1、 Mining principle

at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining

looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:

CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)

mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return

in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes

to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin

Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

< EM > Figure 3: Mine Map (scale of tens of thousands of mining machines) < / EM >

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability

there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises

2. Mine pool

in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance

the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day

3. Cloud computing power

in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative

Mining income and risk mining income can be calculated by the following formula:

Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee

if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee

Mining risks are as follows:

< UL >

at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle

mining difficulty improvement at present, our machines can meet the market demand

5. It's probably tens of thousands of yuan. If you buy more, you'll get back more mining machines. Now you don't earn money. Damn it, you still need electricity, so it's not recommended.

6. Don't think about mining. When you install the miner, the price may drop. As a whole, the electricity bill for one day is not enough. Mining machine, then at least 6 cards to have effect, the previous hd7850 speed is difficult to get a bitcoin a month!

7. The miner is not set right. Give me your contact information. I'll help you remotely

8. Lidar is a kind of remote sensing measurement which uses laser as light source and detects the light wave signal without interaction between laser and detected. The lidar technology using vibration Raman technology is Raman lidar, which is mainly used for atmospheric remote sensing measurement. Raman lidar is a kind of remote sensing technology. As an active remote sensing detection technology and tool, lidar has a history of nearly 50 years. At present, it is widely used in Earth Science and meteorology, physics and astronomy, biology and ecological conservation, military and other fields. Among them, the traditional lidar is mainly used for land vegetation monitoring, laser atmospheric transmission, fine weather detection, global climate prediction, marine environment monitoring and so on. With the rapid development of laser technology, fine spectroscopic technology, photoelectric detection technology and computer control technology, lidar has unique advantages in remote sensing detection height, spatial resolution, time continuous monitoring and measurement accuracy
lidar is a radar system that detects the position, velocity and other characteristics of the target by emitting laser beam. In terms of working principle, there is no fundamental difference with microwave radar: transmitting the detection signal (exciting beam) to the target, and then comparing the received signal (target echo) reflected from the target with the transmitted signal, after proper processing, the relevant information of the target can be obtained, such as the target distance, azimuth, altitude, speed, attitude, even shape and other parameters, so as to realize the target detection Missile and other targets are detected, tracked and identified. According to different detection technologies, lidar can be divided into direct detection type and coherent detection type. According to different functions, it can be divided into tracking radar, moving target indication radar, velocity measurement radar, wind shear detection radar, target recognition radar, imaging radar and vibration sensing radar
the working principle of lidar and radio radar is basically the same, and depends on the detection technology used. The basic structure of the direct detection lidar is quite similar to that of the laser rangefinder. When working, a signal is sent by the transmitting system, which is collected by the receiving system after being reflected by the target, and the distance of the target is determined by measuring the round-trip propagation time of the laser signal. As for the radial velocity of the target, it can be determined by the Doppler frequency shift of the reflected light. It can also be obtained by measuring two or more distances and calculating the rate of change
coherent detection lidar can be divided into monostable and bistable. In the so-called monostable system, the transmitting and receiving signals share one optical aperture and are isolated by the transmitting receiving switch. The bistable system consists of two optical apertures for transmitting and receiving signals respectively. The transmit receive switch is no longer needed, and the rest is the same as the monostable system
lidar is a combination of laser technology and radar technology. It consists of transmitter, antenna, receiver, tracking rack and information processing. The transmitter is a variety of lasers, such as CO2 laser, Nd doped yttrium aluminum garnet laser, semiconctor laser and wavelength tunable solid-state laser; The antenna is an optical telescope; The receiver uses various types of photodetectors, such as photomultiplier tubes, semiconctor photodiodes, avalanche photodiodes, infrared and visible multi detector devices, etc. Lidar uses pulse or continuous wave, and the detection methods include direct detection and heterodyne detection
weather radar is a kind of radar specially used for atmospheric detection. It belongs to active microwave atmospheric remote sensing equipment. The high altitude wind radar, which is used with radiosonde, is only a kind of special equipment for positioning displacement balloons, and is generally not regarded as this kind of radar. Weather radar is one of the main detection tools for warning and forecasting medium and small-scale weather systems (such as typhoon and rainstorm clouds). It works in the frequency band of 30-3000 MHz. Generally, it has high detection sensitivity. Because the detection altitude range can reach 1-100 km, it is also known as the middle stratosphere troposphere radar (MST radar). It is mainly used to detect the vertical distribution of atmospheric dynamic parameters such as wind, atmospheric turbulence and atmospheric stability in clear air
the initial interest of the U.S. Department of defense in lidar is similar to that of microwave radar, that is, it focuses on target monitoring, acquisition, tracking, damage assessment (satka) and navigation. However, because the microwave radar is enough to complete most of the damage assessment and navigation tasks, the military lidar plans to focus on a small number of tasks that the former can not complete well, such as high-precision damage assessment, extremely accurate navigation correction and high-resolution imaging. In military, it is often hoped that the aircraft can fly at low altitude, but the minimum altitude of the aircraft is limited by the ability of sensors to detect small obstacles. Not to mention blocking the balloon line and other confrontation facilities, under 60 meters, all kinds of power lines, high-voltage lines, towers, masts, antenna cables and other small obstacles also have obvious dangers. The existing aircraft sensors, from human eyes to radar, are difficult to detect these dangerous objects in advance, especially at night and in bad weather conditions. Because of its high angular resolution, scanning lidar can form effective images of these obstacles in real time and provide appropriate early warning
lidar can be used to measure the trajectories of various flying targets in military. Such as the tracking and measurement of the initial phase of missile and rocket, the tracking and measurement of aircraft and cruise missile at low elevation, the precise orbit determination of satellite, etc. The combination of lidar with infrared, TV and other optoelectronic equipment forms ground, shipboard and airborne fire control systems to search, identify, track and measure targets. Because lidar can obtain the three-dimensional image and velocity information of the target, it is helpful to identify the stealth target. Lidar can monitor the atmosphere, telemeter the pollution and poison in the atmosphere, and measure the temperature, humidity, wind speed, visibility and cloud height of the atmosphere
the traditional way for marine lidar to alert, search, characterize and track underwater targets is to use large and heavy sonar, which usually weighs 600 kg to dozens of tons. Since the development of Ocean Lidar, namely airborne blue-green laser transmitting and receiving equipment, ocean underwater target detection is simple, convenient and accurate. Especially in the third generation lidar which was successfully developed after 1990s, the functions of GPS positioning and height determination were added to realize the automatic control of route and altitude. For example, the "arms" airborne mine detection lidar developed by Northrop company of the United States can work 24 hours and accurately detect suspicious targets such as underwater mines. The underwater imaging lidar developed by American Kaman space company has more advantages. It can display the shape and other characteristics of underwater targets, accurately capture targets, and take emergency measures to ensure navigation safety
in addition, lidar can also be widely used to counter electronic warfare, anti radiation missiles, ultra-low altitude penetration, missile and shell guidance, and land mine sweeping.

9. There are still some new virtual digital coins that can be mined by computer, such as eth, Zec, Monroe and XRB
because the network wide computing power required by this kind of token is not high, the probability of hash collision of the computing power of personal computer can find out the answer in a short time, so as to obtain block rewards. However, this kind of token generally has little value or high risk, so it is not of great significance< br />
extended data:
mining risk:
1. Electricity charge problem:
if the graphics card "mining" needs to be fully loaded for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated 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 in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
2. Hardware expenditure:
mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining
in addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also on the battlefield. ASIC is specially designed for hash operation, and the computing power is also quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the electricity cost is also lower. It is very difficult to compete with these mining machines, This kind of machine costs more
3. Currency security:
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
4. System risk:
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income
however, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners.
