Bitcoin minerA computer or computer cluster in the Bitcoin network that adds transactions to the blockchain. Anyone with a good Internet connection can be a miner either using a regular PC, which is less feasible every day, or by purchasing specialized hardware known as an "ASIC miner." There are even "cloud mining" services that mine Bitcoin and other cryptocurrencies that users can rent and get paid in digital coins. For information about the mining process, see Bitcoin mining.
|The Bitmain Antminer S9|
|Custom made for computing blockchain hashes, the Antminer S9 was one of the fastest ASIC miner machines on the market at the end of 2017. ASIC miners such as this use a whole lot more power than an ordinary PC, and this unit requires a stand-alone 1600 watt power supply. (Image courtesy of Bitmain Technologies, www.bitmain.com)|
