Mining - EVE University Wiki

Mining is the activity of extracting ore from asteroids, though it is also used to describe ice harvesting and more rarely, gas cloud harvesting. Once extracted, ore can then be refined into minerals. These refined substances are used in the production and maintenance of all player-created items and structures in EVE, such as ships and modules ...

Mining Monero | Monero - secure, private, untraceable

Proof of Work. One of Monero's philosophies is to maintain egalitarian mining, so that everyone can have the possibility to mine. To achieve this, Monero uses a particular algorithm ideated and developed by members of the Monero community: RandomX.This PoW algorithm is ASIC resistant, which means it's impossible to build specialized hardware to mine Monero.

Data Mining | Consumer Risks & How to Protect Your Information
