Streamlining identity verification through blockchain-powered credential delegation
About
The problem it solves **Streamlined KYC Processes** - **For Individuals**: Convert traditional documents (e.g., Aadhaar) into Verifiable Credentials, enabling quicker onboarding across platforms. - **For Organizations**: Reduce time spent on repetitive customer verifications by utilizing verified credentials. **Privacy-Preserving Interactions** - Share only the **necessary parts of information** (e.g., age verification without sharing the date of birth) using **selective disclosure** powered by Zero-Knowledge Proofs. **Cross-Platform Identity Usage** - Use credentials across **multiple blockchains and ecosystems**, eliminating siloed identity systems. **Cost-Efficient Verification** - Avoid repeating on-chain verification processes by utilizing **verification history** stored immutably on the blockchain using Subgraphs **Decentralized & User-Controlled Identity** - Empower individuals to own and control their digital identity without relying on centralized entities. ### **How It Makes Tasks Easier & Safer** **For Individuals** - **Easier Onboarding**: Skip repetitive identity proofs for each new service. - **Data Safety**: Protect sensitive information with **ZK-proofs**, avoiding unnecessary data exposure. **For Businesses** - **Seamless dApp Integration**: Leverage a universal verifier SDK to integrate identity checks effortlessly. - **Cost Savings**: Reduce operational costs through reusable verification results. **For Developers** - **Developer-Friendly Tooling**: Use Graph queries to fetch and verify identity data efficiently. - **Interoperability**: Build cross-chain dApps with built-in support for decentralized identity stan
How it's made
Challenges we ran into **Universal Verifier Contract Issues** - **Access Control Problem**: - The contract lacked proper access control for updating the verification status. - Only the deployer could update the status, preventing validators from executing their roles. - **Debugging & Redeployment**: - Spent significant time debugging why status updates weren't functioning as expected. - Deployed the contract independently to test potential fixes. - With mentor support, identified the issue. #### **Proxy Contract & Subgraph Complexity** - **Challenge with Upgradeable Contracts**: - The Universal Verifier contract uses a **proxy pattern**, enabling upgrades, but this created complexities in **subgraph integration**. - Partners assisted in debugging and implementing the correct subgraph configuration, ensuring smooth integration. #### **Exploration of Alternative Solutions** - **PSE DigiLocker XML**: - Explored this solution but found it too rigid for custom credential issuance (Only PAN Card was doable and the generation for XML was difficult).
