An ASIC miner is a computing device intended for cryptocurrency mining and built mainly on specialized ASIC chips. In essence, it is a narrowly specialized computer whose entire design is subordinated to computing a specific hashing algorithm, for example SHA-256 in the case of Bitcoin.

Because the computing units are optimized for a single task, an ASIC miner delivers high performance and energy efficiency on the corresponding algorithm, noticeably outpacing mining on central processors and graphics cards. This makes such devices the primary tool of industrial mining in networks where ASIC mining has become widespread.

In what form ASIC miners are produced

• As boards installed in an ordinary computer.
• As fully self-contained devices with their own software and cooling system.

It is worth keeping in mind that narrow specialization is both a strength and a weakness: the device is tied to a single algorithm, requires a stable power supply and cooling, and its efficiency depends on the overall difficulty of the network and the operating conditions.
