Professional mining card
Generally, there are professional graphics cards to mine, and the mine is actually bitcoin. Users download the mining software from the computer and then run a specific algorithm. After communicating with the remote server, they can get the corresponding bitcoin. Most of them work by burning the graphics card, so the power consumption is large
the graphics cards and mine cards are usually ATI chips. The bitcoin market is not good, so the miners take out their mining cards and sell them as second-hand
what is mining
to put it simply, mining is to use the chip to perform a calculation related to the random number, and get the answer in exchange for a virtual coin. 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. It's possible that one chip will find the answer in the next second, or ten chips won't find the answer in a week. The more chips compute at the same time, the easier it is to find the answer, and the mining machine with built-in multi chips appears. And a number of mining machines to form a "mine" at the same time mining is to improve efficiency. In the mine pool, multiple "self-employed" join an organization to mine together. No matter who finds the answer and digs out the virtual coin, everyone gets the corresponding reward according to the calculation ability of contribution. This way can make the income of "self-employed" more stable
relationship between mining and graphics card
the stronger the computing power of ant miner, the easier it is to dig out virtual coins. Accordingly, when the more virtual coins are g out, the difficulty of mining will be increased accordingly, so as to control the yield of virtual coins. The virtual currency is not unlimited. The total number of bitcoin is 84 million
the professional mining machine does not use GPU, but a special mining chip, which is an ASIC. This kind of chip can only be used for mining, and has no other functions, but it is highly efficient in its own work and faster than GPU.
Mining graphics card is faster than CPU, professional mining machine is faster than graphics card because: BTC task is a very simple decryption calculation, does not need too many instructions
That is to say, the task of BTC only needs some specific transistorsthe CPU is used to carry out the mining task. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle
the packer of the transaction is the miner, and the income from the miner's packaged transaction is bitcoin
miner's income consists of two parts:
1. Service charge is required for package transaction (users pay part of bitcoin)
2. A reward (bitcoin) will be automatically generated for each block generated
