Description

This curriculum spans the technical, operational, and governance dimensions of deploying blockchain-based identity systems, comparable in scope to a multi-phase internal capability program for enterprise IAM transformation.

Module 1: Foundations of Decentralized Identity Architectures

Select between DID methods (e.g., did:web, did:key, did:ethr) based on organizational trust requirements and integration complexity.
Define root-of-trust models for identity issuance, including centralized, consortium, and fully decentralized trust anchors.
Evaluate ledger choices (permissioned vs. permissionless) for identity anchoring based on compliance, performance, and operational control needs.
Implement key management policies for long-term DID controller key rotation and recovery without compromising immutability.
Map existing enterprise identity sources (LDAP, SAML, SCIM) to verifiable credential issuance pipelines.
Design DID document resolution mechanisms that support high availability and caching in hybrid environments.
Integrate DID-based identifiers into existing IAM user directories without disrupting legacy authentication flows.
Assess cryptographic agility requirements for DID methods to support future-proofing against quantum threats.

Module 2: Verifiable Credentials and Claims Lifecycle Management

Choose credential formats (JWT-VC, LD-Proofs) based on verifier compatibility, signature performance, and metadata richness.
Implement expiration, revocation, and status checking mechanisms using credential status lists or blockchain-anchored registries.
Design schema governance for credential types to ensure interoperability across issuers and avoid fragmentation.
Balance privacy and auditability by deciding which claims are embedded in credentials versus fetched dynamically.
Establish credential issuance workflows with multi-party approval for high-assurance identity assertions.
Implement selective disclosure patterns using zero-knowledge proofs where required by regulatory constraints.
Define retention policies for issued credentials in issuer systems to meet data minimization requirements.
Integrate third-party attestation services for cross-organizational credential validation workflows.

Module 3: Identity Wallet Design and User Control

Select wallet architecture (cloud-hosted, device-bound, hybrid) based on user experience, security, and backup requirements.
Implement secure key storage mechanisms using hardware security modules (HSMs) or secure enclaves.
Design user consent interfaces for credential sharing that comply with GDPR and CCPA notice requirements.
Enable cross-device synchronization of wallet contents without exposing private keys or credentials.
Implement recovery mechanisms (e.g., social recovery, backup phrases) that do not create single points of compromise.
Integrate wallet push notifications for incoming presentations and credential expirations in enterprise workflows.
Support multiple DID controllers per wallet to enable organizational delegation and shared custody models.
Enforce access control policies within the wallet for multi-user devices in shared work environments.

Module 4: Integration with Enterprise IAM Systems

Map verifiable presentations to SAML assertions or OAuth 2.0 tokens for compatibility with legacy applications.
Implement identity bridging services to translate between traditional identity providers and DID-based verifiers.
Configure session management policies that respect the stateless nature of verifiable credentials.
Integrate blockchain identity into existing SSO workflows without increasing user friction.
Design fallback authentication paths for users without blockchain identities during migration phases.
Enforce step-up authentication using high-assurance credentials for privileged access requests.
Log credential verification events in SIEM systems for audit and incident response alignment.
Implement attribute-based access control (ABAC) policies using claims from verified credentials.

Module 5: Governance, Trust Frameworks, and Legal Compliance

Define roles and responsibilities (issuer, holder, verifier) in legal agreements for cross-organizational identity exchange.
Establish trust registries to publish and validate issuer DIDs and credential schemas.
Implement data processing agreements that clarify liability for credential misuse or revocation delays.
Align credential issuance practices with eIDAS, NIST 800-63, or ISO/IEC 18013-5 standards as applicable.
Design dispute resolution workflows for contested credential issuance or revocation.
Document data flows for GDPR data subject rights fulfillment (e.g., right to erasure, access).
Negotiate inter-organizational SLAs for credential verification latency and availability.
Conduct third-party audits of issuer compliance with defined trust framework policies.

Module 6: Scalability, Performance, and Operational Resilience

Optimize DID resolution caching strategies to reduce blockchain read load and improve response times.
Design credential revocation list (CRL) distribution mechanisms that scale to millions of credentials.
Implement load testing for verifier endpoints under peak presentation validation loads.
Deploy redundant DID resolvers across regions to ensure availability during network partitions.
Monitor blockchain node health and transaction confirmation times for anchoring services.
Plan for credential schema versioning and backward compatibility in long-lived systems.
Automate recovery procedures for wallet service outages affecting credential access.
Size infrastructure for identity hubs based on expected credential storage and sync frequency.

Module 7: Security, Threat Modeling, and Incident Response

Conduct threat modeling for wallet phishing, DID spoofing, and replay attacks on verifiable presentations.
Implement rate limiting and anomaly detection on credential verification endpoints.
Enforce strict origin validation for presentation submission to prevent cross-site request forgery.
Design key compromise response procedures including DID deactivation and re-issuance workflows.
Integrate blockchain identity events into enterprise SOAR platforms for automated response.
Perform penetration testing on wallet recovery mechanisms to identify social engineering vectors.
Validate cryptographic implementations against known side-channel and timing attack risks.
Establish forensic logging for credential issuance and presentation without violating privacy.

Module 8: Interoperability and Ecosystem Integration

Adopt W3C and DIF standards for DIDs and VCs to ensure cross-platform compatibility.
Integrate with national digital identity initiatives (e.g., EU EUDI, Canada’s DIACC) using bridge adapters.
Participate in identity networks (e.g., Sovrin, BC Wallet, Microsoft Entra) with defined operational commitments.
Implement schema and context registries to support dynamic credential validation across partners.
Develop API gateways that normalize responses from heterogeneous verifier implementations.
Support multilingual credential display and consent interfaces for global deployments.
Coordinate with industry consortia to align credential schemas for sector-specific use cases.
Test interoperability with mobile wallet providers (e.g., Trust Wallet, BitPay) for consumer-facing services.

Module 9: Migration, Change Management, and Adoption Strategy

Phase migration of legacy identities to DID-based identifiers using dual-identity coexistence periods.
Train helpdesk staff on troubleshooting wallet setup, credential receipt, and recovery issues.
Develop internal communication plans to explain user benefits and responsibilities in self-sovereign identity.
Implement analytics to track credential adoption rates and identify user drop-off points.
Design fallback mechanisms for users who lose wallet access during transition periods.
Coordinate with legal and HR to update employment agreements reflecting digital credential ownership.
Measure ROI of blockchain identity by tracking reduction in identity proofing costs and fraud incidents.
Establish feedback loops with end users to refine wallet UX and credential request workflows.
