## What it is
RandomX is a proof-of-work algorithm optimized for general-purpose CPUs that uses random code execution and memory-hard techniques to resist specialized mining hardware. It is provided as a C++11 static library with a C API, and is used by cryptocurrencies such as Monero and Arweave.

## Use cases
- mine cryptocurrency on CPUs with ASIC-resistant proof of work
- verify proof-of-work blocks with low memory requirements
- integrate a PoW hashing algorithm into a blockchain via a C API
- benchmark CPU performance with a memory-hard workload
- study or audit a formally reviewed PoW algorithm design

## When to choose
- you need a CPU-friendly, ASIC-resistant proof-of-work algorithm for a blockchain
- you want a PoW algorithm with multiple independent security audits
- you need both fast mining and light verification modes with identical results

## When to avoid
- you need GPU or ASIC-friendly mining performance
- you need a general-purpose cryptographic hash function rather than proof-of-work
- your platform cannot provide 256 MiB (light) or 2080 MiB (fast) of shared memory
