Is CPO expensive
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
1t package (10 single-mode groups): the price is 13999 yuan; The price of avalon2 single-mode 100g is 1599 yuan; The price of Avalon 2-generation Miner 2 mole 200g is 2500 yuan. At present, Avalon three generation chips have been released, and Avalon 3 mining machine is about to enter the market.
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad 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 some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned

mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
from the aspect of cost performance, Hangzhou Lianzhong
mining machinery is more practical, stable and faster in cost recovery.
DCC lending chain is not MLM, the specific analysis is as follows:
1. DCC lending chain is a smart lending contract proct based on blockchain technology, which is launched by famous Japanese financial experts and Japanese domestic financial companies. The purpose of loan chain is to give intangible digital assets the same status as real estate, and to carry out mortgage short-term lending and financing lending within the controllable range of value
Second, MLM refers to the illegal act of organizers' development personnel to obtain wealth by developing personnel or requiring the personnel to be developed to obtain the qualification to join in on the condition of paying certain fees. The essence of MLM is "Ponzi scheme", that is to say, the money of later comers is distributed to the income of former comersthe new type of MLM: it does not restrict personal freedom, does not accept ID cards and mobile phones, and does not take big classes collectively. Instead, it uses capital operation as a banner to pull people to cheat money, drives luxury cars, wears gold and silver, and uses money to attract your relatives and friends to join, and finally makes you lose all your money

Network loan risk
1. The virtuality of network transaction leads to the inability to authenticate the credit status of both sides of the loan, which is prone to fraud and default disputes
2. Among the large amount of information about lenders released by the network platform, many of them issued loans in the name of "loan company" and "financing company". In fact, only financial institutions approved by the state can engage in financial services such as credit financing. Those who engage in financial activities without authorization will be investigated for legal responsibility for "illegal fund-raising" and "illegal attraction of public deposits" and disturbing the order of financial management
3. If the loan is issued on behalf of the network platform, then the network platform is lax in self-discipline, or the internal control proceres are invalid, or it is used by others, then the situation of fabricating loan information and illegal fund-raising may occur

2. Details of computer host installation and assembly
the first step of computer installation and assembly: install CPU processor
in the current market, Intel processors are mainly composed of 32-bit and 64 bit Celeron and Pentium (core processor is currently on the market. Core processor is a brand-new processor made by Intel with 0.65 proction process, which adopts the latest architecture and also adopts the LG a 775 interface. Intel will fully promote core processor in the future. Because of the same LGA 775 interface, the installation method is exactly the same as that of Intel 64 bit Pentium Celeron. The 32-bit processor adopts 478 pin structure, while the 64 bit processor is unified to LGA775 platform. As the price gap between the two is no longer obvious, Xiaobian recommends that new users choose the 64 bit LGA775 platform, and the 32-bit 478 pin is no longer the mainstream and is not worth buying
special attention should be paid when installing the processor. You can carefully observe that there is a triangle mark on the corner of CPU processor. In addition, if you carefully observe the CPU socket on the motherboard, you will also find a triangle mark. During installation, the corner printed with triangle logo on the processor should be aligned with the corner printed with triangle logo on the motherboard, and then slowly press the processor into place. This is not only applicable to Intel processors, but also applicable to all processors at present, especially for processors with pin design. If the direction is not correct, the CPU cannot be installed in all parts. We should pay special attention to it when installing
after the CPU is placed in place, close the cover and slightly press down the pressure bar of the processor in the opposite direction. At this point, the CPU is steadily installed on the motherboard, and the installation process is over<
the second step of computer installation and assembly: install the radiator
because the heat of CPU is large, it is particularly critical to choose a radiator with excellent heat dissipation performance, but if the radiator is not installed properly, the heat dissipation effect will be greatly reced. The figure above shows the original heat sink of Intel LGA775 pin interface processor. We can see that compared with the previous 478 pin interface heat sink, it has made a great improvement: the former fastener design has been changed to the current four corner fixed design, and the heat dissipation effect has also been greatly improved. Before installing the heat sink, we need to evenly apply a layer of thermal conctive silicone grease on the surface of the CPU (many radiators have coated silicone grease on the bottom of the CPU when they are purchased, so it is unnecessary to apply another layer on the processor.)
