Bitcoin machine power board
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
Bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
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.
ordinary computer mining was used in the early days of the birth of bitcoin. At that time, the price of bitcoin was low and there were few people playing it, mainly gamers and geeks. At that time, the computing power was very low and no special mining equipment was needed
but in 2012, the price of bitcoin began to rise sharply. Driven by the interests, people began to look for faster mining equipment. At this time, people found that the mining speed of graphics card was relatively fast, and people began to use graphics card for bitcoin mining. This stage is commonly known as "burning graphics card" mining
at the end of 2012, people began to find that the special ASIC miner had faster mining speed. In early 2013, pumpkin Zhang developed the world's first ASIC bitcoin miner. Since then, bitcoin mining has been completely subverted
in the following period of time, under the expulsion of interests, more mining machine manufacturers joined in the proction and development of bitcoin mining machines, the whole network computing power began to soar, and the updating speed of mining machines accelerated. At present, bitcoin mining is almost close to the cost price, or even higher than the cost price. Mining is about energy consumption and electricity price. Avalon's fourth generation 28nm chip has some advantages in energy consumption.
if you haven't played bitcoin or mined before, it's recommended not to buy a miner to mine bitcoin. At present, the profit margin of mining is very low, and retail investors have graally withdrawn from the historical stage of mining. Mining is mainly some large mines, which are deployed in some remote provinces with low electricity price
of course, with free electricity, mining is also possible. If you don't know, you can trust me.
