  • Open Badges 3.0 (1EdTech, final May–June 2024):[^ob30] [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
    • Each OpenBadgeCredential is issued as a W3C Verifiable Credential (VC Data Model 2.0) [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
    • Cryptographically signed by the issuer's DID using EdDSA (eddsa-rdfc-2022) or ECDSA (ecdsa-sd-2023) [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
    • Badge Connect API: OAuth 2.0-authenticated REST endpoints (getCredentials, getProfile, upsertCredential) for credential portability between any compliant platform and any compliant wallet [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
    • Revocation via BitstringStatusListEntry; expiration status must be displayed by conformant Displayers [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
    • CLR Standard 2.0 (Comprehensive Learner Record) co-evolved with OB 3.0; bundles multiple credentials as a longitudinal transcript [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
  • W3C Verifiable Credentials + DIDs: [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
    • Issuer signs VC → Holder stores in DID-keyed wallet → Verifier resolves issuer DID, validates signature, checks status - no callback to issuer required [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
    • DID v1.0 became W3C Recommendation July 2022 [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
    • Blockchain anchoring: credential hash written on-chain; hash mismatch = tamper detection; confidential data stays off-chain [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
    • Verification latency: seconds vs. weeks for legacy background check services [archived source: https://llms-explorer.com/sources/mdb-context-hub/assessment-certification-design/#10-micro-credentials-digital-badges-and-open-badges-30]
  • Employer adoption (verified-as-of: 2026-06-16): Tech-sector ecosystems (Google, Amazon, Microsoft) have built badge ecosystems with direct employer metadata consumption. Outside tech, employer recognition remains uneven - standards-based portability is the primary mitigation against platform lock-in.
