Mining

The technical process of confirming transactions in a blockchain using the proof of work consensus algorithm. Mining is typically centralized by companies known as mining pools which pool physical compute resources in order to increase their probability of confirming blocks.

Proof of work mining is an energy intensive process with a large environmental footprint because of its use of fossil fuels to provide energy for data centres.

See also environmental footprint of crypto, proof-of-work, and proof-of-stake.
