How NoPaper Works

NoPaper is a bridge between your eco-friendly actions and the blockchain. Our system is designed to be fast, secure, and user-friendly.

System Overview

The NoPaper ecosystem consists of three main parts:

  1. The App (Frontend): Your interface for connecting your wallet and uploading digital receipts.
  2. The Brain (Backend & AI): Uses advanced AI (GPT-4o) to instantly verify your receipts and run security checks.
  3. The Ledger (Blockchain): The VeChainThor blockchain, where rewards are sent and impact is recorded forever.

Our Technology

We use world-class technologies to ensure a seamless experience:

  • AI Verification: We use state-of-the-art computer vision to analyze your grocery receipts and identify sustainable purchases.
  • Secure Storage: Your original receipt data is stored in encrypted, private storage, while only a blurred version is used for public blockchain proof.
  • Blockchain Infrastructure: Built on the energy-efficient VeChainThor network, ensuring your rewards are decentralized and verifiable.

The Submission Journey

  1. Capture: You take a screenshot of your digital receipt.
  2. Analyze: Our AI scans the receipt for organic products, eco-friendly certifications, and local produce.
  3. Verify: Security checks ensure you are a genuine user on a genuine device.
  4. Reward: The smart contract automatically sends B3TR tokens to your VeWorld wallet.
  5. Impact: Your contribution to a greener planet is recorded on your profile.
