Nim Ethash

Build Status (Travis)License Stability: experimental

A pure Nim implementation of Ethash, the Ethereum proof of work

Implementation is based on the spec revision 23 (2017-08-03) and under the Apache License v2.

Mining

An unoptimized mining CPU backend is available through the compile-time flag -d:ethash_mining. It requires compilation through the C++ backend.

Optimizations

For maximum speed, compile Ethash with -d:release -d:march_native -d:openmp. This will compile Ethash in Nim release mode, with all supported CPU extensions (AVX2 especially) and with OpenMP multiprocessing On MacOS, OpenMP requires installing GCC-7. It can be done through homebrew.

Original implementation

Original Ethereum implementation is available here.
