Principle of making money by software 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 his paper, Nakamoto stated:"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
mining refers to the use of bitcoin mining machine to obtain bitcoin, that is, the computer used to earn bitcoin. If you can get bitcoin, you can make money this kind of computer generally has professional mining chips and works by installing a large number of graphics cards, which consumes a lot of power. The computer downloads the mining software and then runs a specific algorithm to get the corresponding bitcoin after communicating with the remote server
precautions:
1. It's better to use DIY mining machine, from purchasing accessories to assembly, and then to mining software, to learn, focus, practice and graally understand the blockchain
Mining is actually a fixed investment process: regardless of the currency price, a certain amount of positions will be increased every day3. The bitcoin wallet used to store bitcoin uses military level encryption, which makes it impossible for hackers to steal easily. Bitcoin wallet also allows users to set two passwords, a public account password and a private password. The user of public account password is to let the user receive bitcoin. If users want to withdraw or transfer bitcoin from their accounts, they need to use a private password
Mining is to confirm the transactions in the bitcoin system over a period of time and record the process of forming new blocks on the blockchain. The miners are called miners
Can mining make money? People around me who have been in contact with blockchain have asked me this question. The answer must be yes, otherwise mining will not be the foundation of blockchain development, and countless people will be miners How to dig? Xiao users said they were at a loss. You can use ha Yu miner to mine and experience mining resistance by yourself. You can download software and mine with one click, without any learning cost
Make money by hanging up. However, mining games have risks, sooner or later problems
however, at present, professional Avalon ASIC miner is needed for mining, and it also needs to be included in a mine pool. If you are a retail investor, of course, if you arrange a large mine, you don't need it.
the principle of bitcoin mining is to implement rules made by people and automatically executed by computers
Satoshi Nakamoto, the inventor of bitcoin, has stipulated this rule from the very beginning, and those who participate in bitcoin blockchain must automatically abide by it unconditionally
The content ofrules is generally ,
people who pack the circulation data of bitcoin, arrange it into a fixed size, and then upload it to the blockchain for bitcoin whole network synchronous broadcasting can get 50 bitcoins rewarded by the system
under certain conditions, these rewards will be halved, about once every four years
so how to complete the data packing
the person who wants to complete this action must first have the necessary tools, that is, the software to execute the bitcoin blockchain, and the machine (computer at the beginning) to run the software; Then download and save all the bitcoin transaction data that have been recognized by the whole network. At this time, you become a "node" and a part of protecting the blockchain data
Thenode can only get the priority of the packaged data after running a specific mathematical formula and getting the correct answer. The system will automatically give the reward to the node who gets the priority, who completes the packaging first and then uploads it to the blockchain, and receives and approves it from other nodes
if there is bitcoin service charge in the packaged transaction, the service charge belongs to the node
people think that the process of calculating the mathematical formula and then completing the package to get the reward is just like fishing for gold in the river. It is necessary to discard many wrong answers in order to find the right key to get gold, so people compare this process to mining
so bitcoin mining is not really to dig something, or to use computers to constantly collide and guess. Whoever guesses first wins the reward, that's all
