ShadowRep: Building a Confidential Reputation Protocol with Zama FHE on Ethereum

Description

ShadowRep is a privacy-preserving onchain reputation protocol built using Zama's Fully Homomorphic Encryption (fhEVM). Unlike traditional reputation systems where all scores are publicly visible, ShadowRep keeps attestations and scores encrypted at all times - even while computing on-chain. Key Features: Encrypted attestations using euint64 (1-100 score range) Homomorphic score accumulation with FHE.add() Threshold proofs without revealing exact scores using FHE.ge() Granular access control with FHE.allow() Use Cases: Undercollateralized DeFi lending Anonymous weighted DAO voting Private professional credentials Fair gaming matchmaking Tech Stack: Zama fhEVM (Fully Homomorphic Encryption) Solidity 0.8.27 Hardhat React + TypeScript ethers.js v6 Links: Live Demo: https://shadowrep.vercel.app Verified Contract: https://sepolia.etherscan.io/address/0x41f... #Zamacreatorprogram #FHE #Ethereum #Privacy #Web3 #Blockchain #DeFi #Solidity #HomomorphicEncryption
