unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
mining machine is a tool for procing and mining bitcoin
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
Micro mining machine is a kind of mining machine, which is a computer used to earn bitcoin. This kind of computer generally has professional mining crystal, and works in the way of burning graphics card, which consumes a lot of power. One of the ways to get bitcoin is that users download software from personal computers and then run specific algorithms to communicate with remote servers to get the corresponding bitcoin
functions of mining machine:
mining machine is one of the ways to obtain bitcoin Bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically
The decentralized feature and algorithm ofP2P can ensure that the currency cannot be manipulated by mass proction. Any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers
extended data:
types of mining machine:
1. CDN mining machine
with the emergence of Xunlei game cloud, a new mining machine, called CDN mining machine, appeared. This miner, because it doesn't need too strong performance, is just a router or TV box. Thunderplay cloud uses a unique consensus mechanism, not by contributing computing power, but by contributing network bandwidth and storage space
2. FPGA miner
FPGA miner, it is a hardware base plate, equivalent to a piece of white paper, what kind of function you want to achieve, write what kind of program to it. Compared with ASIC, the chip designed for specific purpose is much more flexible
3. Cloud miner
cloud miner is relative to local mining, which can be compared with the relationship between network disk and local hard disk. In short, you can use other people's mining machines remotely through the network instead of mining machines. It can be said to be a cloud application or a rental hosting service

and then from top to bottom (the arrow represents the funnel orientation)
box (burning procts)
funnel ﹣ box (fuel)
furnace ﹣ funnel
funnel ﹣ box (finished procts)
the lower two spaces can be changed to
leaky bucket → box
or
box ﹣ funnel
to save space
the box can be changed to Replace it with a wooden bucket, and the latent shadow box
box can also be combined with the need to synthesize a large box
1. CPU is mainly optimized for serial instructions, while GPU is optimized for massively parallel operations
2. Modern multi-core CPU aims at instruction set parallelism (ILP) and task parallelism (TLP), while GPU is data parallelism (DLP)
3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications
the CPU needs strong generality to deal with various data types, and at the same time, it also needs logical judgment, and it will introce a lot of branch jump and interrupt processing. All these make the internal structure of CPU extremely complex. GPU is faced with highly unified, interdependent large-scale data and pure computing environment without interruption. GPU uses a large number of computing units and ultra long pipeline, but it only has very simple control logic and saves cache. The CPU not only occupies a lot of space by cache, but also has complex control logic and many optimization circuits. So unlike CPU, GPU is good at large-scale concurrent computing, which is suitable for password cracking
in short, CPU is a general-purpose operation. In short, it means brainless calculation and violent calculation. Whether it's 100 children sharing apples or simulating the earth, it can be decomposed into the most basic calculation of 1 + 1 = 2. GPU is specially designed to deal with high-order mathematical algorithms, such as calculating the relative positions of light source, object, viewpoint and shadow, which requires trigonometric functions to be piled up. The bitcoin digger uses SHA-256, a secure hash function invented by the US National Security Agency, which is generally used for password encryption and decryption. This algorithm can perform a large number of 32-bit integer right-rotate operations, which is very suitable for GPU which is good at large-scale concurrent computing and password cracking.
there is a short circuit in the circuit, resulting in short-circuit current, and the fuse will be blown if the short-circuit current is too large
if there are too many electrical appliances, the fuse will burn, just like the leakage protection switch, if the power is too large, the load will trip
the reasons for frequent fuse blowing are as follows:
check whether the circuit at the back end of the power supply [fuse] is short circuited
check whether the electrical equipment on the line at the back end of the power supply [fuse] is short circuited
check whether the load at the back end of the power supply [fuse] used is too large, and whether the capacity of the fuse is 2-2.5 times of the overload current
check whether the set of power supply [fuse] is tightly installed to avoid poor contact
check whether these fuses are proced by regular factories and meet the standards.
