Credentials
Recipient
In LearnCoin parlance, the human who earned the credential — represented pseudonymously in the signed JSONLD and concretely in off-chain PII storage.
The recipient is the person a credential is about — a student, trainee, professional, or employee. In W3C VC terminology, the recipient is usually the subject; in Open Badges 3.0, they appear inside credentialSubject.
LearnCoin represents recipients in two places. Inside the signed JSONLD, the recipient is a pseudonymous identifier (urn:uuid:...) with a self-sovereign display_name the recipient can update. Outside the signed document, in LearnCoin's Supabase storage, the recipient has a row with email, legal name (if provided), and external identifiers — all under tenant-scoped Row Level Security, all subject to GDPR erasure.
This split — pseudonymous on-chain and in-document, PII off-chain and deletable — is the architectural consequence of ADR-001. Recipients interact with LearnCoin primarily through the magic-link claim flow; they don't typically have LearnCoin accounts. The credential becomes theirs via the claim, not through sign-up.
