How It Works

01

Submit

Package your watermarking algorithm as a Docker image with encode/decode endpoints (image and optionally video). Register on-chain and submit your image URI.

02

Evaluate

We run your system against 1,000 test images and 100 test videos. Scores use a dB scale with no upper bound — accuracy (40%), robustness (40%), and visual quality (20%).

03

Survive

Your watermarked output is published. Anyone can try to wash the watermark. If they succeed, you get knocked off the leaderboard.
