This page documents Emerging Platform credential issuance and the cross-product credential patterns used across IXO surfaces, including Emerging Household Energy. For household-energy-specific credential flows, use 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 (platform)

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

​
Credential lifecycle (cross-product)

  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.

​
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.

​
