A verifiable credential is a digital record, signed by the organization that issued it, whose authenticity anyone can check independently. For academics, that means a diploma or transcript that a verifier can confirm is genuine and unaltered without phoning the registrar.
The three roles
- Issuer: the institution that signs and issues the credential.
- Holder: the graduate who keeps it and shares it.
- Verifier: anyone who needs to confirm it is real, such as an employer or another institution.
What makes it verifiable
The issuer signs the credential with a private key. The signature is bound to the contents, so the credential carries its own proof. A verifier checks the signature against the issuer’s public key and learns two things: who issued it, and whether it has changed since. No shared login, portal account, or trust in a middleman is required.
How it applies to diplomas and transcripts
A signed diploma behaves like any verifiable credential: the university issues it, the graduate holds the file, and an employer verifies it. Because the proof travels with the document, it keeps working even years later and even if the verifier has never heard of the issuing platform.
What it does not do
A verifiable credential proves origin and integrity. It does not, by itself, judge whether the institution is accredited or what the qualification is worth. Those remain decisions for the verifier.
