LumenCheck · Pay to Verify

Instead of bulk uploads, users pay per shutter-trigger to verify the exact spatiotemporal coordinates of the shot, preventing AI-generated deepfakes in night sky competitions. Each exposure is a micro-transactional event that proves 'I was there, and this light is real.'. Anyone can pay 0.01 USDC over x402 to verify someone else's QUIP chain and walk away with a receipt.
