# Kweli: AI + ZK Deepfake Detection Platform Kweli is a youth-centered, privacy-preserving platform that combines AI-based deepfake detection with Zero-Knowledge (ZK) cryptography to verify digital media authenticity. Built for communities, schools, and mobile-first users in Africa, Kweli empowers users to fight misinformation with truth, proof, and transparency. ⚖️ Kweli is a work-in-progress to empower African institutions and civic actors with privacy-first truth verification tools and powered by Zero-Knowledge cryptography. 📸 From verifying deepfakes to securing media evidence, Kweli is building tools for digital justice in the age of disinformation. 🔐 Support the mission: Sponsor our work on GitHub --- ## 🌍 Project Goals - **Detect and flag deepfakes** using an efficient AI model (EfficientNet-lite). - **Verify authenticity** of media using ZK proofs stored on Starknet blockchain. - **Educate youth and educators** with culturally-relevant digital literacy toolkits. - **Enable trust at scale** with decentralized infrastructure and community testing. --- ## 🧠 Tech Stack - **Frontend**: Expo + React Native - **Backend**: Flask (Python), IPFS - **AI Model**: EfficientNet-lite (TensorFlow/Keras) - **Blockchain**: Starknet (Cairo 2, Sierra, Starknet.py) - **ZK Layer**: Cairo ZK circuits for proof generation and validation - **Dev Tools**: EAS, VSCode, GitHub Actions --- ## 📦 Key Features - Image and video upload with live fake/real prediction - ZK-based verification with hash commitments stored on-chain - A/B tested UI for accessibility - Offline caching and async uploads for low-connectivity areas - Real-time logging of false positives and negatives --- ## 📅 Milestone-Driven Development The project is executed over 12 months with quarterly milestones: - **Q1**: Pilot rollout, onboarding, user testing - **Q2**: AI model optimization, ZK module, blockchain stress tests - **Q3**: Curriculum co-development, community testing - **Q4**: Policy advocacy, na …
