Quick Start

Download

Pre-built binaries are available from Releases.

Usage

# Basic CPU mining to a pool
./miner -o pool.example.com:3333 -u YOUR_WALLET -p x

# With JSON config (recommended)
./miner -c config.json

# Enable GPU mining
./miner -c config.json --opencl --cuda

# Benchmark mode
./miner --bench=1M

# Show all options
./miner --help

Configuration

The recommended way to configure the miner is via JSON config file:

{
    "autosave": true,
    "cpu": true,
    "opencl": false,
    "cuda": false,
    "pools": [
        {
            "url": "stratum+tcp://pool.example.com:3333",
            "user": "YOUR_WALLET",
            "pass": "x",
            "keepalive": true
        }
    ]
}

Building from Source

Dependencies

Linux (Ubuntu/Debian):

Linux (Fedora/RHEL):

sudo dnf install git cmake gcc gcc-c++ libuv-devel openssl-devel hwloc-devel

macOS:

brew install cmake libuv openssl hwloc

Windows:

• Visual Studio 2019 or later
• CMake 3.10+
• vcpkg for dependencies

Build Commands

mkdir build && cd build

# Standard build
cmake ..
cmake --build . --config Release

# With GPU support
cmake .. -DWITH_OPENCL=ON -DWITH_CUDA=ON

# Static binary
cmake .. -DBUILD_STATIC=ON

# Debug build
cmake .. -DCMAKE_BUILD_TYPE=Debug -DWITH_DEBUG_LOG=ON

# Minimal build (reduce binary size)
cmake .. -DWITH_KAWPOW=OFF -DWITH_GHOSTRIDER=OFF -DWITH_ARGON2=OFF

CMake Options

Option	Default	Description
WITH_HWLOC	ON	Hardware topology support
WITH_RANDOMX	ON	RandomX algorithms
WITH_ARGON2	ON	Argon2 algorithms
WITH_KAWPOW	ON	KawPow (GPU only)
WITH_ETCHASH	ON	ETChash/Ethash (GPU only)
WITH_PROGPOWZ	ON	ProgPowZ (GPU only)
WITH_BLAKE3DCR	ON	Blake3 for Decred
WITH_GHOSTRIDER	ON	GhostRider algorithm
WITH_OPENCL	ON	AMD GPU support
WITH_CUDA	ON	NVIDIA GPU support
WITH_HTTP	ON	HTTP API
WITH_TLS	ON	SSL/TLS support
WITH_ASM	ON	Assembly optimizations
WITH_MSR	ON	MSR mod for CPU tuning
BUILD_STATIC	OFF	Static binary
BUILD_TESTS	OFF	Build unit tests

HTTP API

When built with -DWITH_HTTP=ON, the miner exposes a REST API:

Endpoint	Method	Description
/1/summary	GET	Mining statistics
/1/threads	GET	Per-thread details
/1/config	GET	Current configuration
/1/config	PUT	Update configuration

Example:

curl http://127.0.0.1:8080/1/summary

Performance Optimization

Huge Pages (Linux)

# Temporary
sudo sysctl -w vm.nr_hugepages=1280

# Permanent
echo "vm.nr_hugepages=1280" | sudo tee -a /etc/sysctl.conf

# 1GB pages (best performance)
sudo ./scripts/enable_1gb_pages.sh

MSR Mod (Intel/AMD CPUs)

The miner can automatically apply MSR tweaks for better RandomX performance. Requires root/admin privileges.

sudo ./miner -c config.json

Testing

# Build with tests
cmake .. -DBUILD_TESTS=ON
cmake --build .

# Run tests
ctest --output-on-failure
