Blockchain-Based Identity Verification

This project involves creating a Decentralized Identity Verification System (DID) using smart contracts, where users can verify their identity for online platforms in a secure, permissionless, and privacy-focused manner. It can integrate advanced blockchain features and address real-world issues like user verification, data privacy, and fraud prevention.

🔐 How it works:

Users create unique digital IDs linked to their wallets.

Credentials are stored securely on IPFS, accessible only with user approval.

Selective disclosure ensures users share only the required data.

Tech Stack:

Solidity for smart contract logic.

IPFS for decentralized storage.

React for a seamless user experience.

Challenges I Faced:

Gas Optimization: Smart contracts need to minimize costs while maintaining efficiency.

Data Security: Balancing transparency and privacy on a public blockchain.

User Experience: Making blockchain tech accessible to non-tech users.

Innovations I Introduced:

Implemented Layer-2 solutions to reduce gas fees.

Used zero-knowledge proofs for privacy-focused verification.

Created a simple UI that integrates seamlessly with Metamask.
