Practical overview
When it fits
Use Ethash when a C/C++ project needs the library's Ethash or ProgPoW algorithm functions, or when you want to build its included micro-benchmark.
Who it is for
- C/C++ developers integrating Ethash or ProgPoW computation into an application.
- Developers building or using a micro-benchmark for proof-of-work computation.
- Teams creating a project-specific wrapper around the library's exported algorithm functions.
Documented uses
- Build the library from source with CMake.
- Inspect the exported functions and their documentation in ethash.hpp.
- Build and run the included ethash-bench micro-benchmark.
- Use the implementation as a base for a compatible C/C++ integration or wrapper.
Requirements & limits
- The project is a library rather than a ready-to-use mining application or service.
- CMake is the documented build system; the README gives a short source-build sequence.
- The README points to ethash.hpp for exported functions and API documentation.
- The dataset-size calculation is described as naive and as forking well only up to a 40-bit number.
- The repository specifies the Apache-2.0 license.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Build Ethash from source and find its exported functions
Compile the library with CMake, then locate the API documentation in ethash.hpp.
Before you start
- CMake
- A C/C++ build environment
Steps
Create a build directory and enter it.
Run cmake .. from that directory.
Run cmake --build . to build the project.
Consult include/ethash/ethash.hpp for exported functions and documentation.
Expected outcome
A CMake-built library and a reference to its documented exported functions.
Guide limitations
- The build instructions do not specify platform-specific dependencies or integration steps.
- Building the library does not by itself establish that a particular application is compatible.
Build and run the Ethash micro-benchmark
Use the repository's documented benchmark tool to examine proof-of-work computation performance.
Before you start
- CMake
- A C/C++ build environment
Steps
Build the project from source using CMake.
Build and run the ethash-bench tool included with the library.
Expected outcome
The repository's micro-benchmark tool is built and run.
Guide limitations
- The documentation does not specify benchmark options or provide a comparison procedure.
