Title: Blockchain for Digital Identity | Self-Sovereign Identity Solutions

Objective:
To explore the role of blockchain technology in addressing digital identity challenges and preventing identity theft through self-sovereign identity (SSId) solutions. The goal is to provide a comprehensive analysis of how blockchain can enhance identity management, ensure privacy, and enable a decentralized, user-controlled identity system.

Deliverables:

1. A detailed analysis of blockchain's role in digital identity, focusing on self-sovereign identity solutions.
2. A comparative evaluation of blockchain-based SSId solutions with traditional identity management systems.
3. Recommendations for implementing SSId solutions using blockchain technology.
4. A roadmap for integrating blockchain and SSId into existing digital identity frameworks.
5. A report on the technical, security, and performance aspects of blockchain-driven SSId solutions.

Key Considerations:

• Industry Best Practices: Adhere to frameworks such as ISO/IEC 24745 (Digital Identity) and NIST (National Institute of Standards and Technology) guidelines.
• Quality Expectations: Ensure solutions meet security compliance, scalability, and performance benchmarks.
• Technical Specifications:
  • Utilize blockchain architectures like Hyperledger Fabric or Polkadot for scalability and cross-chain interoperability.
  • Implement cryptographic primitives such as zk-SNARKs and zk-STARKs for privacy-preserving identity verification.
  • Use identity management systems (IMS) compliant with standards like ISO 19797-2.
• Challenges and Solutions:
  • Scalability: Optimize blockchain layer architectur
