Digital credentials replace paper certificates with cryptographically signed records that any employer, institution, or verification platform can check instantly. The learner owns a credential they can embed in a LinkedIn profile, email signature, or portfolio page. Employers check authenticity with one click — no phone calls to the registrar.
Blockchain vs signed PDF credentials
- Blockchain-anchored — a hash of the credential is written to a public or consortium blockchain. Tamper-evident because the chain is immutable.
- Signed PDF / Open Badges — credentials are digitally signed with the issuer's private key and verified against a published public key. Simpler to implement; equally tamper-evident without distributed ledger overhead.
