Mining RandomX
The miner most people run, the pool that has no operator, and the coins that use RandomX or a variant of it.

Which coins use RandomX?
Monero is the coin RandomX was built for, but not the only one: XMRig's own coin table lists Monero, Zephyr and Townforge on standard RandomX, and Wownero, ArQmA, Graft and YadaCoin on variants of it. What each runs, and what such a list does not tell you.

P2Pool: mining RandomX without a pool operator
P2Pool is a decentralised Monero pool: a sidechain of its own, merge-mined with Monero, that pays each miner straight from the block, with no fee and nobody holding the funds. Its main, mini and nano chains, what it needs to run, and how a RandomX miner connects.

XMRig: the RandomX miner, set up and explained
XMRig is the open-source miner most RandomX mining runs on: CPU first, with OpenCL for AMD and a plugin for NVIDIA, and official builds for Windows, Linux, macOS and FreeBSD. Its RandomX algorithm names, the settings that matter, and the 1% donation.
