Questions tagged [mining]

The process of using a computer to verify transactions on the Monero network. Mining helps keep the network safe, since it is unlikely that one person or group of people can control a large portion of the total mining power. Monero is mined on the CryptoNight algorithm, and it is mined with both CPUs and GPUs.
