Description

Cipher-Streak is a privacy-preserving check-in system built with Fully Homomorphic Encryption (FHE) on Ethereum. It allows users to record and verify their on-chain activity without revealing sensitive data. Private Check-ins: User data is encrypted before submission, ensuring full privacy. On-chain Computation: Homomorphic operations enable encrypted data processing directly on-chain. Owner-only Decryption: Only users can view their real check-in counts. Built with React + TypeScript + Vite on the frontend, Solidity smart contracts on Sepolia Testnet, and a mock FHE setup (via Zama SDK) for development. Future versions will integrate true FHE for complete end-to-end encryption.
