A mining rig is a computing device for mining cryptocurrency, most often built on the basis of a computer with several graphics cards. The chance of receiving a block reward depends on its power.
FPGA is a field-programmable gate array, a semiconductor chip that can be configured for specific tasks after it has been manufactured. In mining, it occupies an intermediate position between graphics cards and ASICs.
A graphics processing unit (GPU) is the computing chip of a graphics card, capable of simultaneously processing many parallel tasks. Thanks to this property, GPUs long remained the main hardware for cryptocurrency mining.
An ASIC is an integrated circuit designed to perform a single task. In mining, such chips are used for the most efficient computation of a specific cryptocurrency algorithm.
An ASIC miner is a cryptocurrency mining device built on specialized ASIC chips. It is tailored to a specific algorithm and is significantly more efficient than universal hardware.
In traditional financial systems, new banknotes are simply printed by the governments of countries whenever they need them. But digital currencies come into being differently. They are generated by computers, and this process is called mining. The essence of mining is that a multitude of computers that are not
