CerChain

Decentralized Identity System for KYC and NFT-Based Certificates

Overview

This system leverages blockchain technology to provide a secure and decentralized identity management solution. It enables users to undergo KYC (Know Your Customer) verification and mint their certificates as NFTs (Non-Fungible Tokens), ensuring authenticity, security, and transparency.

Key Features

✅ Decentralized Identity (DID) – Users control their blockchain-based identity without relying on centralized authorities.
✅ KYC Verification – A secure process to verify users while maintaining privacy through cryptographic proofs.
✅ NFT Minting for Certificates – Institutions can issue tamper-proof digital certificates as NFTs.
✅ Smart Contract-Based Security – Ensures immutability and ownership tracking on the blockchain.
✅ Storage on IPFS/Arweave – Certificate metadata is securely stored in decentralized file systems.
✅ Wallet Authentication – Supports MetaMask, WalletConnect, and other Web3 wallets.

Technology Stack

🔹 Blockchain: Ethereum, Polygon, zkEVM, or other L2 solutions
🔹 Smart Contracts: Solidity (ERC-721 / ERC-1155 for NFTs)
🔹 Frontend: Next.js, React.js, TailwindCSS
🔹 Identity & KYC: Verifiable Credentials (Polygon ID, ENS, Zero-Knowledge Proofs)
🔹 Storage: IPFS, Arweave, Filecoin
🔹 Backend: Node.js (Express/NestJS), Web3.js/ethers.js for smart contract interactions

Use Cases

📜 Education & Certifications – Universities and training institutions can issue digital diplomas.
🏦 Finance & Compliance – Financial institutions can verify user identities securely.
🔐 Corporate Identity Management – Companies can validate employee credentials and professional certifications.

This system ensures privacy-first identity management, reduces fraud, and enables a trustless verification process using blockchain technology. 🚀
