Decentralized Identity Patterns

Design patterns, reference architectures, and best practices for implementing decentralized identity (DID) and verifiable credentials in regulated supply chain environments.

📌 Overview

This repository explores how decentralized identity systems can support:

  • Regulatory compliance – Verified identity for authority interactions
  • Data sovereignty – User-controlled credentials without centralized gatekeepers
  • Interoperability – Cross-border identity verification
  • Privacy preservation – Selective disclosure and zero-knowledge proofs

🏗️ Architectural Patterns

1. Authority-Operator Identity Model

Enabling logistics operators to prove identity and access rights to regulators without exposing sensitive data.

Components:

  • Decentralized Identifiers (DIDs)
  • Verifiable Credentials (VCs)
  • Selective disclosure mechanisms

2. Multi-Stakeholder Trust Frameworks

Coordinating identity across carriers, forwarders, 3PLs, and regulatory bodies.

Key Considerations:

  • Governance and trust root establishment
  • Revocation and credential validity
  • Cross-border recognition

3. Privacy-Preserving Verification

Using zero-knowledge proofs and cryptographic commitments to verify claims without revealing underlying data.

Techniques:

  • Selective disclosure
  • JSON-LD with linked data proofs
  • Zero-knowledge attestations

🔐 Security Considerations

  • Key management and custody models
  • Credential revocation and expiration
  • Attack vectors in identity systems
  • Regulatory audit trail requirements

📚 Reference Material

  • W3C Decentralized Identifiers (DIDs) Specification
  • W3C Verifiable Credentials Data Model
  • JSON-LD and linked data proofs

Maintained as part of ongoing research in decentralized compliance infrastructure.
