Building from Source

Prerequisites

All Platforms:

• CMake 3.10+
• C++11 compatible compiler
• libuv
• OpenSSL (for TLS support)

Linux:

sudo apt-get install build-essential cmake libuv1-dev libssl-dev libhwloc-dev

macOS:

brew install cmake libuv openssl hwloc

Windows:

• Visual Studio 2019+ with C++ workload
• vcpkg for dependencies

Build Miner Core

cd core
mkdir build && cd build

# Standard build
cmake ..
cmake --build . --config Release -j$(nproc)

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

# Static build (portable)
cmake .. -DBUILD_STATIC=ON

# Minimal build (RandomX only)
cmake .. -DWITH_ARGON2=OFF -DWITH_KAWPOW=OFF -DWITH_GHOSTRIDER=OFF

Build Proxy

cd proxy
mkdir build && cd build
cmake ..
cmake --build . --config Release -j$(nproc)

Build All Components

From the repository root:

make build-miner          # Build miner core
make build-miner-proxy    # Build proxy
make build-miner-all      # Build all components

Configuration

Miner Config (config.json)

{
    "autosave": true,
    "cpu": true,
    "opencl": false,
    "cuda": false,
    "pools": [
        {
            "url": "stratum+tcp://pool.example.com:3333",
            "user": "YOUR_WALLET",
            "pass": "x",
            "keepalive": true,
            "tls": false
        }
    ],
    "http": {
        "enabled": true,
        "host": "127.0.0.1",
        "port": 8080,
        "access-token": null
    }
}

Proxy Config (proxy-config.json)

{
    "mode": "nicehash",
    "pools": [
        {
            "url": "stratum+tcp://pool.example.com:3333",
            "user": "YOUR_WALLET",
            "pass": "x"
        }
    ],
    "bind": [
        {
            "host": "0.0.0.0",
            "port": 3333
        }
    ],
    "http": {
        "enabled": true,
        "host": "127.0.0.1",
        "port": 8081
    }
}

HTTP API

Both miner and proxy expose HTTP APIs for monitoring and control.

Miner API (default: http://127.0.0.1:8080)

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

Proxy API (default: http://127.0.0.1:8081)

Endpoint	Description
GET /1/summary	Proxy statistics
GET /1/workers	Connected workers
GET /1/config	Current configuration

Performance Tuning

CPU Mining

# Enable huge pages (Linux)
sudo sysctl -w vm.nr_hugepages=1280

# Or permanent (add to /etc/sysctl.conf)
echo "vm.nr_hugepages=1280" | sudo tee -a /etc/sysctl.conf

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

GPU Mining

# AMD GPUs - increase virtual memory
# Add to /etc/security/limits.conf:
# * soft memlock unlimited
# * hard memlock unlimited

# NVIDIA GPUs - optimize power
nvidia-smi -pl 120  # Set power limit

Testing

# Run miner tests
cd core/build
ctest --output-on-failure

# Run proxy tests
cd proxy/build
./tests/unit_tests
./tests/integration_tests
