A miner is also called a person who mines cryptocurrencies.
Mining farm - consists of two or more miners connected to a network and usually located in the same room. In terms of computing power, it is significantly superior to the miner. The main means of mining, since the constant complication of information decryption requires more powerful equipment.
There are two types of mining farms.
Pool - several mining farms networked via the Internet. This allows you to combine the computing power of miners to increase the efficiency of mining. The pool is able to decrypt blocks relatively quickly, which individual miners or mining farms cannot handle.
Solo farm - one mining farm, not connected to the pool. Such a farm has large computing power and does not need to be combined with other mining farms.
Important: the reward for pool members directly depends on the power they provide to decrypt the block.
Also mining farm can be divided into two groups.
Home - most often located in a residential area (apartment) and is characterized by relatively low computing power.
Industrial - located in the hangar and has a gigantic performance. Brings in much more money than a home farm, but requires a huge investment in equipment, electricity and maintenance.
The central processing unit (CPU) is a relatively low-powered piece of hardware that was used in the early days of mining. The processor is slow to cope with the same type of operations, as it is designed to solve different problems. The downside is poor performance.
To date, CPU mining is not cost-effective, although it can be used to mine new cryptocurrencies.
A video card (graphic processor; GPU) is a more powerful device that solves many of the same tasks faster. Advantages: optimal combination of price and power, acceptable noise level, maintainability, versatility (works with different cryptocurrencies), long warranty period (3 years). The disadvantage is the relatively low power.
GPU mining is suitable for home environments. This option is ineffective for bitcoin mining.
A field programmable gate array (FPGA) is a device that is modified depending on the tasks. In terms of power, FPGA is comparable to a video card with lower power consumption. Therefore, FPGA mining is sometimes called a type of GPU mining.
ASIC miner is a special device for mining, consisting of chips and a fan. Advantage - maximum computing power. Disadvantages: very high price, loud noise, non-repairability, rapid obsolescence, narrow specialization (“sharpened” for one cryptocurrency), short warranty period (90-180 days).
The use and maintenance of ASIC miners is possible only in industrial conditions. These devices are ideal for bitcoin mining.
