Usage

Edit the included example-config.json to suit your needs (pool address, number of threads, etc), then run:

powhasher -c your-config.json

While the hasher is running, press Enter to get statistics.

What is it?

This is a simple CLI miner for modern x86 CPUs, powered by the yellowsun CryptoNight hash implementation and the cn-stratum pool client. It once hosted unusually fast Cn/Cnv1 core loops I wrote in assembly, but the current Cnv2 backend is pure Rust based on stdsimd intrinsics.

Supported platforms

If you'd like to use this on a platform that isn't Linux, all it needs is a hugepage mmap implementation for your weird choice of operating systems. PRs for the yellowsun project are welcome!

powhasher's Issues

static build errors on ubuntu for RHEL

Trying to build a COMPLETELY static binary. The build machine is Ubuntu 18, and the run machine in RHEL. I suspect the error might have something to do with the fact I tried installing rust and cargo via sudo apt install rather than the shell script method. (However, I later removed the apt packages and successfully installed rust via the shell - so maybe not?)

Hi, I have some questions regarding this project

Hi, I have some questions regarding this project:

  1. Am I able to import it as a library/crate into my own Rust code and integrate it into my own software so I can compile all into a single executable?
  2. Does it support either Beam, Zcash or Monera or any other privacy respecting cryptocurrency?
  3. How efficient is it compared to something like gminer?
  4. Do you guys get a commission from my cryptomining if I were to use this library/crate?
  5. How well maintained is this project? How many people are working on it?
