The new format puts the credential in the recipient&#8217;s hands instead of on the issuer&#8217;s server, signs it cryptographically at issuance, and aligns with the W3C Verifiable Credentials Data Model that modern wallets and Europass already speak.<\/p>\n<p class=\"wp-block-paragraph\">For issuers, the version matters. A platform that issues Open Badges 2.0 in 2026 locks recipients into a fragile, server-dependent format. A platform that issues 3.0 gives recipients a credential that travels and verifies for the lifetime of the holder. This guide covers what changed, what to look for in a platform, and how to migrate.<\/p>\n<h2 class=\"wp-block-heading\">What Open Badges 3.0 is<\/h2>\n<p class=\"wp-block-paragraph\">Open Badges 3.0 is a credential specification published by 1EdTech in 2023 that defines how skill credentials are structured, signed, and verified. The spec inherits the underlying intent of Open Badges 2.0 (machine-readable skill credentials issued by any authoritative body) but rebuilds the technical foundation on top of the W3C Verifiable Credentials Data Model.<\/p>\n<p class=\"wp-block-paragraph\">The plain-English description: a 3.0 badge is a JSON document, signed by the issuer&#8217;s cryptographic key, that contains a verifiable claim about a recipient (typically a skill, achievement, or competency). The signature is the verification method. The verifier does not need to call the issuer&#8217;s server to confirm authenticity; the signature confirms it.<\/p>\n<h2 class=\"wp-block-heading\">Structural differences: hosted assertion vs. signed verifiable credential<\/h2>\n<p class=\"wp-block-paragraph\">The biggest change between 2.0 and 3.0 is the location of trust. In 2.0, the credential lives as a hosted JSON file on the issuer&#8217;s server. The recipient receives a link. The verifier fetches the JSON, parses it, and trusts that the issuer&#8217;s server has not lied. If the issuer&#8217;s URL changes or the server goes down, the credential breaks.<\/p>\n<p class=\"wp-block-paragraph\">In 3.0, the credential lives with the recipient. The issuer signs it cryptographically at issuance time, then sends the signed credential to the recipient (typically into a wallet or platform under the recipient&#8217;s control). The verifier reads the signed credential directly, checks the signature against the issuer&#8217;s published public key, and confirms authenticity offline. The issuer&#8217;s server can disappear; the credential still verifies.<\/p>\n<p class=\"wp-block-paragraph\">This shift solves three real problems. Long-term portability: the credential outlives the issuer&#8217;s URL. Recipient ownership: the credential belongs to the recipient, not to the issuer&#8217;s database. Decentralized verification: verification works offline and across platforms.<\/p>\n<h2 class=\"wp-block-heading\">Anatomy of an Open Badges 3.0 credential<\/h2>\n<p class=\"wp-block-paragraph\">A 3.0 credential carries the same conceptual elements as a 2.0 badge but structured as a verifiable credential. The required pieces include the issuer profile (who issued it, with a decentralized identifier where applicable), the recipient identifier (who it was issued to), the achievement (what skill or competency was demonstrated), the criteria (what the recipient had to do to earn it), the evidence (proof of work or assessment), the issuance date, and the cryptographic proof.<\/p>\n<p class=\"wp-block-paragraph\">The cryptographic proof is the new piece. It binds the issuer&#8217;s private key to the credential at issuance time, producing a signature that any verifier can check against the issuer&#8217;s published public key.<\/p>\n<h2 class=\"wp-block-heading\">Relationship to W3C Verifiable Credentials and DIDs<\/h2>\n<p class=\"wp-block-paragraph\">Open Badges 3.0 is, technically, a profile of the W3C Verifiable Credentials Data Model. Every 3.0 badge is a VC; not every VC is a 3.0 badge. This matters because it means 3.0 badges are interoperable with the broader VC ecosystem: digital wallets, identity systems, employment verification platforms, and other credential types (educational diplomas, professional licenses, ID credentials) that all use the same VC base.<\/p>\n<p class=\"wp-block-paragraph\">Decentralized Identifiers (DIDs) are an associated standard that lets issuers and recipients hold cryptographic identities outside of centralized providers. A 3.0 badge can identify issuer and recipient using DIDs rather than email addresses or URLs. For institutional issuers, DID support is forward-compatible with the direction the W3C ecosystem is moving.<\/p>\n<h2 class=\"wp-block-heading\">Europass and other interoperability<\/h2>\n<p class=\"wp-block-paragraph\">The European Union&#8217;s Europass framework for credential portability aligns with the W3C Verifiable Credentials Data Model that Open Badges 3.0 builds on. A 3.0 badge issued correctly can be read and verified in a Europass wallet, and Europass credentials can be expressed in Open Badges 3.0 form. For issuers serving European recipients or participating in EU education and training programs, this interoperability matters.<\/p>\n<p class=\"wp-block-paragraph\">Beyond Europass, the broader W3C ecosystem includes wallets and identity systems from multiple vendors. A 3.0 badge that uses standard signatures and standard data models works across all of them.<\/p>\n<h2 class=\"wp-block-heading\">What to evaluate in a platform claiming Open Badges 3.0 support<\/h2>\n<p class=\"wp-block-paragraph\">Marketing claims vary from genuine 3.0 support to &#8220;we&#8217;ll add it soon&#8221; framed as if it shipped. Five questions separate the two.<\/p>\n<p class=\"wp-block-paragraph\">First, does the platform issue credentials in the actual 3.0 signed Verifiable Credential format, or does it produce 2.0 hosted assertions wrapped in 3.0 language? Ask to see a sample credential JSON. Second, does the platform support cryptographic signing at issuance, with the issuer&#8217;s controlled key? Or does it rely on the platform&#8217;s own key (which makes the credential dependent on the platform staying live)? Third, can the credential be exported and read by a third-party wallet? If not, the credential is locked in. Fourth, does the platform support Decentralized Identifiers for issuer or recipient identity? This is forward-compatible. Fifth, does the platform provide a verifier that works offline (signature check only) or only an online verifier that hits the platform&#8217;s server? The first is real 3.0; the second is 2.0 with new branding.<\/p>\n<h2 class=\"wp-block-heading\">Migration: moving 2.0 badges to 3.0<\/h2>\n<p class=\"wp-block-paragraph\">An issuer with an existing 2.0 badge portfolio has three migration options. Issue new credentials going forward in 3.0 while leaving past 2.0 credentials in place (the most common pattern). Re-issue past credentials as 3.0 versions where the recipient consents and the platform supports re-issuance. Maintain dual issuance for a transitional period where every new credential goes out in both formats.<\/p>\n<p class=\"wp-block-paragraph\">The recommended approach for most issuers is option one. Past 2.0 credentials remain verifiable for as long as the issuer&#8217;s URL stays live; new credentials issued in 3.0 verify offline and travel for the lifetime of the recipient. Over time, the 3.0 portfolio compounds and the 2.0 portfolio sunsets naturally.<\/p>\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n<h3 class=\"wp-block-heading\">Are Open Badges 3.0 credentials backward-compatible with 2.0?<\/h3>\n<p class=\"wp-block-paragraph\">Not directly. The data structures differ significantly. Most platforms supporting 3.0 also continue to support 2.0 for backwards compatibility, but a single credential is either 2.0 or 3.0, not both. Some platforms can dual-issue (the same credential in both formats), which preserves compatibility during a transition.<\/p>\n<h3 class=\"wp-block-heading\">Do I need DIDs to use Open Badges 3.0?<\/h3>\n<p class=\"wp-block-paragraph\">No. DIDs are optional. 3.0 supports DID-based identifiers and traditional URL-based identifiers. DIDs offer stronger long-term portability and decentralization but add operational complexity. Most issuers in 2026 are starting with URL-based identifiers and adding DID support over time.<\/p>\n<h3 class=\"wp-block-heading\">Can a 3.0 badge be revoked?<\/h3>\n<p class=\"wp-block-paragraph\">Yes. 3.0 supports revocation through status lists that verifiers check during verification. A revoked credential will verify as cryptographically valid but flagged as revoked. This is the same model the broader VC ecosystem uses.<\/p>\n<h3 class=\"wp-block-heading\">How can a recipient store a 3.0 badge?<\/h3>\n<p class=\"wp-block-paragraph\">In a digital credential wallet that supports the W3C Verifiable Credentials format. Several wallets exist as of 2026, and most credentialing platforms also offer a recipient portal as the default storage option. The credential can be exported and moved between wallets.<\/p>\n<h2 class=\"wp-block-heading\">Next steps<\/h2>\n<p class=\"wp-block-paragraph\">For new credential programs in 2026, choose a platform with genuine Open Badges 3.0 issuance, cryptographic signing, and offline-verifiable exports. For existing 2.0 programs, plan a transition that issues new credentials in 3.0 while leaving past credentials in place.
