How Monero's proof of work works

Published Apr 27, 2026 How Monero’s proof of work works Monero’s proof of work is called RandomX. Monero does not ask miners to run the same tiny hash function over and over. It asks them to run a small random program on a virtual machine, hit memory hard while doing it, and then hash the result. Bitcoin’s proof of work is great for specialized chips because the work never changes. RandomX was built to do the opposite. It tries to make efficient mining look as much like a normal CPU workload as.
