Jimpson's NFT Generator

A robust Python-based NFT generation system using Stable Diffusion, featuring automatic watermarking and hash verification for blockchain integration. This tool powers the NFT collection at jimpsons.org.

Features

• AI-Powered Image Generation: Leverages Stable Diffusion v1.5 for creating unique vector-style artwork
• Automated Watermarking: Embeds a custom watermark to protect intellectual property
• Blockchain-Ready: Generates SHA-256 hashes for each image, ensuring verifiable uniqueness
• CUDA-Optimized: Utilizes GPU acceleration for faster image generation
• Memory-Efficient: Implements xformers optimization when available

Prerequisites

pip install torch diffusers pillow text

Project Structure

project/ ├── watermark/ │ └── logo_for_watermark.png ├── cache/ ├── main.py └── README.md text

Usage

1. Place your watermark image in the watermark/ directory as logo_for_watermark.png
2. Run the script:

python main.py text

3. Enter your prompts when prompted. The script will:
   • Generate a unique image based on your prompt
   • Add your watermark
   • Calculate a SHA-256 hash
   • Save the image with a UUID filename

Hash Verification

Each generated image comes with a SHA-256 hash that can be verified online. The hash is calculated using the following process:

• Image is converted to RGB format
• Pixels are processed in BGR order for consistency
• SHA-256 hash is generated from the raw pixel data

Configuration

The script includes several customizable parameters:

Image Generation Settings num_inference_steps=30 guidance_scale=10.0 height=512 width=512 Watermark Settings watermark_size = image.width // 5 # 20% of image size watermark_position = (image.width - watermark.width - 10, image.height - watermark.height - 10) text

Security Features

• Unique UUID-based filenames for each generation
• Consistent hash generation for blockchain verification
• Watermark protection for intellectual property
• Negative prompts to avoid generating realistic human faces

Technical Details

The system uses:

• RunwayML's Stable Diffusion v1.5 model
• CUDA acceleration with float16 precision
• PIL for image processing
• SHA-256 for hash generation
