Miner

A person or business that mines Proof of Work (PoW) cryptocurrency. Cryptocurrency miners use powerful CPU, GPU, and ASIC hardware to search through different values of a nonce while looking for rare hash value. When mining PoW cryptos, miners can be incentivized by winning coin rewards in the form of unmined coins as well as earning fees for verifying transactions. Miners are a desirable and necessary part of PoW blockchains and the hash power they send to the blockchain is instrumental in keeping the network secure.
