The principle diagram of CPU mining

In short, mining is the use of chips for a random number related calculation, get the answer in exchange for a virtual currency. Virtual currency can be exchanged for the currency of each country through some way. The stronger the computing power, the faster the chip can find this random answer. Theoretically, the more virtual coins can be proced per unit time. Because it's about random numbers, you can only get rewards if you happen to find the answer

"in the absence of central authority, it not only encourages miners to support bitcoin network, but also enables bitcoin's currency circulation system to have the initial source of money injection."

Nakamoto compares the generation of bitcoin by consuming CPU power and time to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer network, digital signature and interactive proof system

each network node concts 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 their confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain

Nakamoto himself designed the first version of bitcoin mining program, which was later developed into the first generation of widely used mining software bitcoin, which was popular from 2009 to mid-2010

each bitcoin node 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 SHA-256 hash value of the previous data block. The mining node tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target

extended data

at the earliest, bitcoin miners were mining through Intel or AMD CPU procts. But because mining is a computing intensive application, and with the continuous improvement of mining number and equipment performance, the difficulty graally increases, now using CPU mining has no profit or even loss

as of 2012, since the first quarter of 2013, miners graally began to use GPU or FPGA and other mining equipment [5]. At the same time, a large number of ASIC devices were launched in mid 2013

since July 2013, the computing power of the whole network has shown a straight-line rise e to the large number of ASIC equipment put into operation. Based on the average computing power in July 2013, all CPU mining equipment has been unable to generate positive revenue, and FPGA equipment is close to no revenue

according to the estimation of average computing power in September 2013, the existing small ASIC mining equipment developed for indivials will also be close to no positive revenue in the next 1-2 months. A large amount of computing power is monopolized by cluster ASIC mining equipment with 5 th ash / s or more. Because of no profit, indivial mining is almost squeezed out of mining groups. Some bitcoin miners have raised funds to build machine rooms and install a large number of mining equipment in places where low-cost electricity can be obtained

in order to save the cost of mining, some bitcoin miners make mining programs into malicious programs to infect other people's computers on the network to mine for themselves

1. Download the mining software and unzip it. Right click: "start. CMD" and select "Edit" from the pop-up menu

Paste and modify it to the receiving address of the wallet you got before, so that the mine you got from mining goes into your wallet

2. Double click start.cmd to start mining

for the first time, the words "reboot" may appear. You can follow its English operation, right-click "start. CMD", select "run as administrator", and then restart the computer. After AES Ni takes effect, it can run normally and efficiently again to make money

It depends on the computing power of GPU and CPU instead of the computing speed. Although there is no big difference, because the computing principle of graphics card is different from CPU, and mining needs distributed computing. In this kind of computing, graphics card GPU is better than CPU

The working principle of CPU is:

1, take instructions: the CPU controller reads an instruction from memory and puts it into the instruction register. The format of the instruction is generally like this: the operation code is the MOV, add, JMP and other symbol numbers in the assembly language; The address of the operands indicates where the operands required by the instruction are, whether they are in memory or in the internal registers of the CPU

2. Instruction decoding (decoding): the instruction in the instruction register is decoded to determine what operation the instruction should perform (that is, the operation code in the instruction) and where the operands are (the address of the operands)

3. Execute the instruction (write back), and write back the results of the execution phase in a certain format. The results are often written into the CPU internal register for the subsequent instructions to access quickly

extended data:

CPU receives data and instructions from memory, processes these instructions, and sends the processing results back to memory. The results can be displayed and stored, and they are executed in this way again and again, until the power failure. The internal working process of CPU is: Controller - arithmetic unit - accumulator - memory - Register - accumulator

the working principle of CPU is like a factory's processing of procts: the raw materials (program instructions) entering the factory are sent to the proction line (logic operation unit) through the scheling and distribution of the material Distribution Department (control unit), and the finished procts (processed data) are proced and then stored in the warehouse (storage unit), finally waiting to be sold on the market (for the application program to use)
