1. < UL >
this is mainly e to the 51% attack, because before some of the world's well-known mines, e to the low rate and convenient use, many miners went to those large mines to mine. As a result, the computing power of the mines soared, approaching or even exceeding 51% of the global computing power many times
bitcoin community has also raised a big discussion about 51% attack for many times,. The mine pool operators also called on the miners to move to other mines in a responsible manner, and finally 51% of the attacks were solved. Many of China's miners have moved to fish ponds
most of the new miners have joined the fish pond because they don't know about the global mine ponds, and many of the previous mines have died e to poor management

< UL >open the website, input the mobile phone number, select how many CPUs you want to use to mine, the default is to use 50% of the CPU to mine, click to generate your exclusive command and
is such a simple operation
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

Mining app, mining on the mobile phone or forget it, on the point of computing power of the mobile phone, mining is basically impossible, to mine or have to dig on the computer. This is a screenshot of the ha Yu miner I used before. Take a look
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. The miner is not set right. Give me your contact information. I'll help you remotely
7. 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.
