Zero-Knowledge Proof Badge

Zero-Knowledge Proof (ZKP) Badge is a smart contract that issues NFT badges to verified users while ensuring privacy and security using ZKP principles and AI-powered fraud detection.

Description

šŸ›”ļø Zero-Knowledge Proof Badge

šŸ“Œ Project Description

Zero-Knowledge Proof (ZKP) Badge is a smart contract that issues badges as NFTs to verified users without revealing any sensitive information. The contract leverages ZKP principles and AI-powered fraud detection to ensure secure and privacy-preserving credential verification.

šŸš€ Features

šŸ” Privacy-Preserving Badge System

  • Issues NFT-based ZKP Badges for verified users without exposing personal data.

  • Uses Zero-Knowledge Proofs (ZKPs) to authenticate users off-chain while storing only verification results on-chain.

šŸ¤– AI-Powered Verification & Fraud Detection

  • AI-based Identity Verification: Uses AI models to detect deepfake attempts and fake identity proofs before issuing verification.

  • Behavioral Analysis: AI monitors suspicious patterns (e.g., multiple verification attempts) to prevent Sybil attacks.

  • Anomaly Detection: Machine learning helps detect irregular badge claims and unauthorized activity.

šŸ”„ Automated Verification with AI

  • Document Analysis: AI scans and validates user credentials (e.g., government IDs, certificates) before allowing badge minting.

  • Facial Recognition: AI-powered identity matching with liveness detection ensures only real users get verified.

  • Adaptive Learning: The AI model continuously improves based on previous verification attempts.

šŸŒ Interoperable & Decentralized

  • Deployable on Ethereum, Polygon, BNB Chain, and other EVM-compatible networks.

  • IPFS-based decentralized storage for proof metadata.


šŸ› ļø How It Works

  1. User submits credentials (ID, document, or biometric data).

  2. AI model verifies authenticity (detects fraud, deepfakes, and inconsistencies).

  3. ZKP system validates credentials off-chain.

  4. Smart contract mints a ZKP NFT Badge if verification is successful.

  5. Users can use their badge to prove their status without revealing details.


šŸ”„ Use Cases --> Web3 Identity & Reputation: Users can prove their expertise or qualifications without revealing private info. --> Access Control: Restrict access to DAOs, events, or platforms based on badge verification. --> Credential Verification: AI-enhanced ZKP badges can represent KYC-verified individuals or certified professionals.

āœØ What's New? āœ… AI-Powered Identity Verification (Deepfake detection, biometric checks)

āœ… AI-Based Fraud & Anomaly Detection (Sybil attack prevention, behavioral analysis)

āœ… Automated AI-Driven Credential Validation

āœ… Expanded Use Cases (Web3 Identity, KYC, DAO Access Control, etc.)
