ProofPay - Social Payments Platform

A trustless task payment platform supporting Soft, zkTLS, and Hybrid proof systems on the XION blockchain. Create tasks, submit verifiable proofs, and get paid automatically with cryptographic verification or manual review.

🎯 Features

• Soft Proofs: Manual review for subjective work (content creation, design, etc.)
• zkTLS Proofs: Cryptographic verification of API responses (instant, no human review)
• Hybrid Proofs: zkTLS verification + manual review window for complex tasks
• Real-time Updates: Live task status updates via Supabase realtime
• Push Notifications: OneSignal integration for mobile alerts
• Secure File Storage: Signed URLs for evidence uploads
• Auto-release Timers: Hybrid tasks auto-release unless disputed

🚀 Quick Demo

One-command setup:

npm run demo:setup

This starts:

• Blockchain indexer (port 3001)
• Mock zkTLS verifier (port 3002)
• React Native app with test data
• Supabase realtime sync

Demo takes 3-5 minutes - see DEMO.md for complete walkthrough.

Innovation

• First social payment app with integrated zkTLS verification

🛡️ Proof Types

• None: No proof required
• Text Proof: Enter a short explanation
• Photo Proof: Attach a photo
• zkTLS Proof: Zero-knowledge proof for advanced verification

Clone the repository

� Blockchain Security
