The Itz'at standard · eets-AHT, from the Maya word for sage

The Itz'at. Verified anywhere.

Itz'at is the credential standard behind Miatz Certify: a signed, revocable, machine-readable credential that a stranger — or their AI agent — can check in seconds without asking us for permission.

What the credential contains

Six things, all checkable

A PDF certificate asserts. An Itz'at carries the material a reader needs to test the assertion themselves.

Issuer — their brand, their key

The credential is signed under the issuing organisation's own did:web. Their name is on it; Miatz operates the machinery. That is the opposite of a platform badge.

Holder — identified, not exposed

A hashed email binds the credential to a person, or the holder's own DID when they present from a wallet. The raw address never travels inside the credential.

Achievement — with the criteria attached

The name of what was earned, the criteria that had to be met, the exam blueprint it aligns to, and a link to the evidence. A reader can see what the bar actually was.

Validity & status

validFrom and validUntil for expiry, plus a credentialStatus entry pointing at one slot in a Bitstring Status List. Revoking or expiring flips a single bit — no takedown request, no email chain.

Proof — an Ed25519 signature

A Data Integrity proof (eddsa-rdfc-2022) over the whole credential. A VC-JWT export is available for systems that are already JWT-native. Tamper with one character and the proof fails.

Endorsement — the Itz'at mark itself

Alongside the issuer's signature sits a Miatz-issued EndorsementCredential over that issuer: a second, independent signature attesting they are a verified Itz'at member operating under the scheme's governance.

The same credential, as a machine reads it:

{
  "type": ["VerifiableCredential", "OpenBadgeCredential"],
  "issuer": "did:web:creds.example.com",
  "credentialSubject": {
    "id": "did:example:holder",
    "achievement": {
      "name": "Example Certified Developer",
      "criteria": { "narrative": "Passed blueprint EX-200, 78/100 cut score" },
      "alignment": [ /* exam blueprint domains */ ]
    }
  },
  "validFrom": "2026-07-23",
  "validUntil": "2028-07-23",
  "credentialStatus": {
    "type": "BitstringStatusListEntry",
    "statusListIndex": "94567"
  },
  "proof": { "cryptosuite": "eddsa-rdfc-2022", "proofValue": "z58…" }
}

Illustrative shape, trimmed for reading. The Miatz EndorsementCredential over the issuer is a second, separately signed document.

How verification works

Three checks, no permission needed

Every Itz'at verification — by a hiring manager, a partner portal, or an AI agent calling the verify tool — is these three steps in this order.

01

Resolve

Read the DIDs named in the credential and fetch their DID documents over HTTPS — the issuer's own domain, plus did:web:creds.miatz.com for the endorsement. Public keys can be cached or pinned.

02

Check both signatures

The issuer's signature proves authorship of the achievement. The Miatz endorsement proves the issuer is inside the Itz'at scheme. Two independent keys, two independent checks.

03

Check the status list

Fetch the Bitstring Status List named by credentialStatus and read the one bit for this credential. Set means revoked or expired. The list covers many credentials at once, so reading it reveals nothing about who is asking.

None of those three steps calls a Miatz API. That is deliberate: a credential whose validity depends on its vendor still being in business is not a credential, it is a subscription.

A0 – A4

Where the Itz'at sits on the ladder

A4 is the top of the closed assurance vocabulary — and the only level that is never for sale.

  1. A0No markSelf-attested completion; nobody checked.issued by: Any tenant
  2. A1Assessed on miatzScored against a stored rubric, tamper-evident, signed, machine-verifiable.issued by: Any tenant, automatic
  3. A2Kanan ProctoredIdentity bound, session attested, anomalies logged and reviewable.issued by: Tenants with a Kanan-certified proctor on record
  4. A3T'aan DefendedRecorded oral examination on the candidate's own decisions, scored on reasoning.issued by: Tenants on the assessment tier
  5. A4Itz'atDSAT-gated, real work, proctored AND defended.issued by: miatz only — never licensed

Standards

Nothing proprietary in the trust path Available

Every layer of an Itz'at is an open, published specification. We wrote none of them, which is exactly why they are worth building on.

StandardWhat it does hereStatus
Open Badges 3.0The credential format. EndorsementCredential is a native OB 3.0 construct — the Itz'at mark is not a bolt-on.Committed
W3C VC 2.0Open Badges 3.0 is a W3C Verifiable Credential, so any conformant VC verifier reads it. Data Integrity proofs plus VC-JWT export.Committed
Bitstring Status ListRevocation and expiry as one bit in a large shared list — checkable without telling the issuer which credential you looked up.Committed

“Committed” means it is the specification Miatz Certify is being built against and the shape every issued Itz'at will take. “Roadmap” means planned and not yet live — we would rather say that plainly than let a spec logo imply something we have not shipped.

Open rubric · v0

The Itz'at Score: nine dimensions, published

AI-fluency scores in the Itz'at family are computed against this rubric — from observed real work plus periodic oral vivas, never from a multiple-choice test alone. We publish it because a bar you can't read isn't a bar.

DimensionWhat it measures
A · DelegationChoosing what to hand to AI — and what not to; agent-vs-chat fit for the task.
B · DescriptionGoals, context, constraints and success criteria stated; work decomposed into checkable pieces.
C · DiscernmentVerifying output before adopting it: running it, tracing claims, testing — not vibes.
D · DiligenceSecurity, IP and privacy hygiene; honest disclosure of AI involvement.
E · Iteration craftRefining with intent vs blind retrying; knowing when to restart from scratch.
F · Tool leverageUsing skills, agents, MCP and multiple models where they genuinely help.
G · EconomyModel choice, token and cost awareness — engineering judgment applied to spend.
H · GroundednessBlast-radius thinking before delegation; signing the deed; knowing when NOT to use AI.
T · Thinking (Tuukul)Calibration (stated confidence vs actual outcomes), gate discipline, premortems, reflection streaks.

Professional-level Itz'at AI-Fluency cannot be earned without the H and T strands — observed consequence-awareness and calibrated thinking from real work. Every rendered score carries a “how computed” note; estimates are labeled and missing data is never shown as zero. The T-strand is trained by Miatz Tuukul.

The mark

Why “Itz'at · Verified by Miatz” never comes off

Issuers white-label everything a learner sees. The verification surfaces are the one exception, and the mark on them is backed by a signature rather than a style guide.

Itz'at · Verified by Miatz

It is provable, not decorative

The mark corresponds to a real EndorsementCredential signed by Miatz over the issuer. A verifier can check it independently, which is what separates a trust mark from a logo anyone could paste on.

It travels with the credential

Verify page, share link, QR code, PDF — the mark appears on every surface a stranger might land on, so the question “who stands behind this?” is answered wherever the credential is read.

It says what it means

The endorsement attests that the issuer is identity-checked, that their exam scheme was reviewed, and which integrity tier the exam ran at. It does not claim Miatz taught the course or graded the candidate.

Where this is today

Straight about what is live

Miatz issues Itz'at credentials to its own cohort graduates today, each with a hosted verification page anyone can open — that part is live and in use.

The full standard described on this page — per-issuer did:web signing, Open Badges 3.0 / W3C VC 2.0 output, Bitstring Status List revocation and the Miatz endorsement co-signature — is the committed architecture of Miatz Certify and is being built now. Wallet delivery follows it.

We publish the target before it ships because organisations choosing a credential vendor need to know what they are being locked into. In this case: as little as we could arrange.

Questions

Itz'at FAQ

What is Itz'at?

Itz'at is Miatz's credential standard and trust mark. An Itz'at credential is issued on Miatz and verifiable anywhere: an Open Badges 3.0 / W3C VC 2.0 credential signed under the issuing organisation's own did:web, revocable through a Bitstring Status List, and co-signed by Miatz as a member of the scheme.

What does an employer actually have to do to verify one?

Nothing technical, in the simple case: open the hosted verify page or scan the QR and read the live result. If they want to verify it themselves, they resolve two DID documents, check two signatures and read one status bit — no account and no Miatz API call required.

Does verification still work if Miatz disappears?

That is the design goal of choosing these standards: the signature, the DID documents and the status list are public artifacts on ordinary web infrastructure, and a verifier that cached the issuer's key can check a credential offline. The honest caveat: the key-custody and mirroring commitments that turn that architecture into a guarantee are still being written down — until they are published, treat this as design intent rather than a promise.

Who signs an Itz'at — the company or Miatz?

Both, and they mean different things. The issuing organisation signs the achievement: they are the authority on what their exam tested. Miatz signs an endorsement over that issuer: identity-checked, scheme-reviewed, integrity tier disclosed. A verifier can accept one, the other, or insist on both.

How does this relate to the Itz'at a Miatz learner earns?

Same standard, one issuer. A Miatz cohort graduate's Itz'at is issued by Miatz itself under the same format and the same verification path any tenant gets. How a learner earns one — the gates, the auditable record — is explained on the credential page.

Where does an Itz'at sit next to a formal qualification?

It is not a formal academic qualification and does not present itself as one. It is a professional credential that says a named person met a published, evidence-backed bar on a named date, and it hands any reader the means to check that claim independently.

Can a company remove the Miatz mark and ship it fully white-label?

Everything else is theirs: their domain, their DID, their branding on the certificate and the academy. The verification surfaces are the exception — the verify page, link, QR and PDF always carry "Itz'at · Verified by Miatz", because that is the part a stranger is being asked to trust.
