currency mining) The competitive process that verifies and adds new transactions to the blockchain for a cryptocurrency that uses the proof-of-work (PoW) method. The miner that wins the competition is rewarded with some amount of the currency and/or transaction fees. Following are the ways mining is performed. See proof-of-work algorithm
Anyone can purchase specialized miner hardware and connect to the Internet. This was more feasible in the early 2010s than it is today. However, new currencies come online all the time, and if they employ the proof-of-work (PoW) method rather than proof-of-stake (PoS), regular computers or computers with high-end GPUs may be sufficient for mining.

Organizations combine their resources to obtain a huge amount of mining hardware. Mining pools are also open to the public, whereby anyone can add their computers to the network.

People can rent time on a cloud mining service and pay a monthly fee. See cloud mining
The puzzle that miners attempt to solve for Bitcoin and Ethereum, the two major cryptos, consumes a lot of electricity. Known as the "proof-of-work" consensus algorithm, the Digiconomist website (www.digiconomist.net) said Bitcoin and Ethereum together consumed as much energy as Indonesia. However, in 2022, Ethereum changed its consensus method to proof-of-stake (PoS), which uses minimal electricity (see Ethereum 2.0
). Contrast with crypto minting
