Issue once. Verify anywhere. Trust by signature.
Sovio DigiCreds is a complete verifiable credential ecosystem — issuance, holder wallet and verification — built on open standards. Replace paper degrees, PDF certificates and per-issuer portals with cryptographically signed, instantly verifiable credentials.
Every credential, wallet and verifier speaks the same language. W3C, OpenID, IETF and ISO — end to end. No vendor lock-in.
Credentials are everywhere — and verifiable almost nowhere.
Credentials are still PDFs, scans and registrar phone calls.
Degrees, professional certifications and government IDs live as paper or PDF. Verification means calling registrars, checking portals one by one, or accepting scanned copies at face value. The process is slow, expensive — and increasingly vulnerable to sophisticated, AI-generated fraud.
Per-issuer portals never add up to an ecosystem.
Universities build their own degree portals. Certification bodies maintain isolated registries. Government ID programmes run their own apps. Holders juggle dozens of logins. Verifiers integrate per issuer — or simply do not verify. Without a shared format, wallet and trust model, scale is impossible.
Issuer publishes a Decentralized Identifier
A university, certification body or government department publishes its DID (did:web, did:key or did:ion). The DID anchors the issuer's public keys and trust metadata.
No central registry. No vendor lock-in.
University to employer — verified in fifteen seconds.
- 00:00University issues degreeRegistrar signs a Bachelor of Science credential with the institutional DID.
- 00:02Delivered to graduateCredential is pushed to the graduate's DigiCreds wallet via OpenID4VC.
- 00:05Graduate applies for a jobEmployer's hiring system sends an OpenID4VP presentation request.
- 00:08Selective disclosureGraduate shares degree name and issuer — not GPA, not date of birth.
- 00:11Signature verifiedEmployer validates Ed25519 signature against the university's DID document.
- 00:13Status & expiry checkedRevocation status resolved via Bitstring Status List. Credential is current.
- 00:15Hire confirmedCryptographically verifiable proof of authenticity. Audit trail closed.
Six guarantees. Not policy — properties.
- 01Every credential is a signed W3C Verifiable Credential — tamper-evident by construction.
- 02Holders own their credentials in a wallet — issuer portals optional.
- 03Selective disclosure via SD-JWT — reveal only what the verifier needs.
- 04Verification is one API call — signature, issuer trust, status, expiry.
- 05Privacy-preserving revocation — no issuer callback during verification.
- 06Open standards end to end: W3C VC, OpenID4VC, DIDComm, ISO mDL.
Built on W3C, OpenID, IETF and ISO — end to end.
Verifiable credentials engineered for every issuer and verifier.
For architects, security engineers and integration leads.

SD-JWT lets the holder reveal only what's needed — "over 18" without a birth date, "degree holder" without a GPA. Privacy is a property, not a policy.
