fractal-miner

Fractal Miner is a CUDA-based mining application that performs hashing operations and connects to a mining rpc for cryptocurrency mining. This guide will help you set up and run Fractal Miner on your system.

Requirements

CUDA Toolkit: Ensure you have the CUDA Toolkit installed on your system. This application is compatible with CUDA version 12.6.
CURL: Required for making HTTP requests.
nlohmann/json: For JSON parsing.

Installation

Clone the repository:

git clone https://github.com/naufalprtm/fractal-miner.git
cd fractal-miner

Install dependencies:
- CURL: Install CURL on your system. For example, on Ubuntu you can use:
```
sudo apt-get install libcurl4-openssl-dev
```
- nlohmann/json: Download and install the nlohmann/json library. You can use a package manager like vcpkg:
```
vcpkg install nlohmann-json
```

Build the project:

chmod +x install.sh && chmod +x build.sh
./install
./build

Configuration

start node https://github.com/fractal-bitcoin/fractald-release Create a config.json file in the same directory as the executable with the following format:

{
    "rpc_url": "http://IP:PORT", 
    "user_name": "test", 
    "password": "test",
    "address": "bc1pxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}

Replace "rpc_url", "user_name", and "password" with the appropriate values for your mining rpc.

Running the Miner

Start the miner:

./fractal_miner

TEST Running the Miner

./fractal-miner --benchmark

Monitor the output:

The miner will display the GPU temperature, hash result, and hashrate. It will also attempt to connect to the mining rpc using the provided configuration.

Details Hashing: The miner performs hashing operations using a CUDA kernel defined in sha256.cu. The hashing result is displayed as a hexadecimal string. GPU Monitoring: GPU temperature is monitored using a separate thread defined in monitor_gpu_temperature.cu. HTTP Requests: The miner uses the CURL library to communicate with the mining rpc. Ensure that CURL is correctly installed and configured on your system.
