This page documents Emerging Platform credential issuance capabilities. It is platform-scoped and reusable across solutions. For household-energy-specific credential flows, use /platforms/Emerging/itmo-credentials.

​
What this covers

  • credential issuance lifecycle
  • claim-to-credential relationship
  • holder and verifier interactions
  • status, revocation, and re-issuance patterns

​
Supported credential flow

  1. Create or receive a claim.
  2. Validate claim completeness and issuer authority.
  3. Issue a verifiable credential linked to subject DID.
  4. Publish status references for verifier checks.

​
Security and privacy baseline

  • Sign credentials with issuer-controlled keys.
  • Store only necessary metadata on registry state.
  • Keep sensitive payloads in encrypted storage where needed.
  • Enforce Capability-based permissions for issuance and revocation.

​
Cross-product IXO dependencies

  • IXO Protocol for verifiable registry state: /articles/ixo-blockchain
  • IXO Matrix for encrypted credential payload handling: /articles/ixo-matrix
  • Impact Hub Registry for claims and status references: /platforms/Emerging/registry

  • Schema reference: /platforms/Emerging/itmo-schema

This page documents a cross-product IXO dependency. It describes credential lifecycle patterns used across IXO surfaces, including both Emerging Platform and Emerging Household Energy.

​
What this page covers

  • credential issuance flow
  • validation and verification checkpoints
  • revocation and status handling
  • where credentials fit in household-energy workflows

​
Credential lifecycle

  1. Define the credential schema and required evidence.
  2. Submit or evaluate claims against schema rules.
  3. Issue credential to the subject DID.
  4. Verify signature, issuer authority, and status.
  5. Revoke or supersede credentials when state changes.

​
Household Energy usage

In Emerging Household Energy, credentials are used for household, device, and reporting evidence flows. For end-to-end implementation, continue with:
  • /platforms/Emerging/household-monitoring
  • /platforms/Emerging/household-reporting
  • /platforms/Emerging/itmo-credentials

IXO dependencies

  • Identity model: /platforms/Emerging/digital-identifiers
  • Registry state: /platforms/Emerging/registry
  • dMRV capability: /platforms/Emerging/dmrv
