Answers, not records
Verifiers ask specific questions and receive signed answers. Transcripts and personal files stay with the issuer.

How it works
Issue once. Verify anywhere. Revoke instantly.
Join as an accredited issuer
Your institution joins the network as a named organization. Accreditation bodies attest which issuers are recognised, and that record is public.
Issue the credential
The full record, including the holder's personal details, is stored in your institution's private collection. The shared ledger records only that your institution attested an issuance.
Answer verification questions
A verifier asks a precise question, such as "Is this licence current?". Your node answers and signs the answer. The verifier gets a yes or no, not the record.
Revoke or renew
A suspension, revocation or renewal is an attested event on the ledger. The next verification reflects it immediately.
Keep it verifiable for life
An oversight body or successor institution can be a declared member of your collection, so credentials stay verifiable even if the issuer closes.
Who sees what
Proof for the verifier. Privacy for the holder.
Collection membership and attestation metadata are visible. Private payload access depends on the organizations declared in each collection.
| Information | Issuer | Verifier that asked | Other network organizations | Validators |
|---|---|---|---|---|
| Full record and personal details | Yes | No | No | No |
| Answer to a verification question | Yes | Yes | No | No |
| That the issuer attested an issuance or revocation | Yes | Yes | Yes | Yes |
| Issuer accreditation | Yes | Yes | Yes | Yes |
| Issuance and revocation policies | Yes | Yes | Yes | Yes |
An oversight body or successor institution receives personal records only when it is a declared member of the issuer’s private collection.
Features
Everything a credential needs to be trusted.
Instant revocation
Suspensions and revocations are ledger events, so every later check sees the current status.
Know who can issue
Accreditation bodies attest which institutions are recognised. Verifiers can reject credentials from diploma mills automatically.
Multi-party credentials
Joint degrees, co-signed certificates and board-plus-exam-body licences use And and OutOf policies.
Designed for long-term verification
ML-DSA post-quantum signatures protect credentials that must stay trustworthy for a whole career.
Verification history
Issuers can see which organizations verified a credential, giving holders and regulators a clear record.
Issuance policy
Multi-institution trust, written into the credential.
Each issuing action carries an attestation policy committed to the ledger. A verifier can see exactly which organizations had to vouch for a credential before it existed.
- A licence needs the board and at least one recognised exam body.
- Revoking it needs two of three oversight organizations, so no single party can do it alone.
- Joint degrees can require

The problem
A PDF and a phone number are not proof.
Hiring a nurse, engineer or graduate still means emailing registrars, waiting on hold with licensing boards and trusting documents that anyone can edit.
Forgeries are cheap
Fake degrees and licences are sold online and look identical to the real thing. Checking properly takes days that hiring teams do not have.
Revocations go unseen
A suspended licence stays valid on paper. Employers rarely learn about a revocation until something goes wrong.
Verification overshares
To confirm one fact, an employer often receives a full transcript or record containing far more personal data than needed.
Records disappear
Colleges close, boards merge and systems are replaced. Graduates are left unable to prove what they earned.
Who it is for
Issuers, verifiers and the people in between.
University registrar
Fewer manual requests and a permanent, trusted record for alumni.
Licensing board
Public protection that works in real time, not at the next renewal.
Hiring and screening teams
Signed verification answers, with less personal data to store and protect.
Questions
What issuers ask first.
Is personal data put on a blockchain?
Not in readable form. Names, dates of birth, grades and records stay in the issuer's private collection under its own retention policies. The shared ledger holds attestations and status changes, not personal files.
Do verifiers have to join the network?
Organizations that verify often, such as hospitals or screening firms, can join with a verifier role. Occasional verifiers can use a verification service operated by a network member. In both cases the answer is signed by the issuer.
How does a holder share their credential?
Holders receive a verification reference from the issuer that they can give to an employer. The employer uses it to ask the issuer's node a specific question, and only that question is answered.
What happens if our institution closes?
A successor institution or oversight body can be a declared member of your collection. It holds the records and can keep answering verifications under the same published policies.
Why post-quantum signatures?
A degree issued today may be checked 40 years from now. ML-DSA is a NIST-standardized signature scheme designed to resist forgery by future quantum computers.
