DID & Verifiable Credentials System

[grantfox-oss]

Priority: Medium
Epic: Identity & Security

Description

While a DID module skeleton exists, implement full decentralized identity support with verifiable credentials for user identity verification and KYC.

Direction

1. Complete DID module implementation
2. Implement W3C-compliant verifiable credentials
3. Add zero-knowledge proof verification
4. Build VC issuer and verifier services
5. Integrate DID with existing authentication system
6. Create DID document management UI/API

Definition of Done

• Users can create and manage DID identities
• KYC credentials are issued as verifiable credentials
• ZKP verification enables privacy-preserving checks
• DID-based authentication works alongside traditional JWT
• All DID documents are stored and resolvable

Acceptance Criteria

• ✅ W3C DID Core specification is fully implemented
• ✅ Users can prove KYC status without revealing raw data
• ✅ VC signatures are cryptographically verifiable
• ✅ DID authentication is as secure as traditional methods
• ✅ DID documents are available on standard resolvers

Hi Team,

I am writing to submit my application to design and implement our core Decentralized Identifier (DID) and Verifiable Credentials (VC) system. Establishing a robust, self-sovereign identity framework is essential for building trustless user verification, secure cryptographic handshakes, and tamper-proof credential tracking without relying on vulnerable centralized identity providers.

I will architect a secure, fully interoperable identity layer that adheres strictly to standard W3C specifications, allowing users to safely manage their identifiers and share verifiable, cryptographically signed claims.
