ZOREAL Mark

Alternatives to World ID

World ID is, in World’s words, a simple, secure tool to prove you are a unique human without sharing your personal information: a credential from an Orb iris scan, an NFC government document or a selfie check, held in World App, which a platform integrates to receive a zero-knowledge proof that a unique human is behind an action; World states nearly 18 million people have verified at an Orb across 160 countries. ZOREAL Mark is a signed marker a holder pastes into a post or comment so that anyone can check that a real human, verified by ZOREAL, vouched for exactly that text on that page at that time. This page sets a proof-of-human credential beside a vouching mark: what each proves, what each binds to, who has to integrate, and what each costs.

Information last reviewed 11 September 2026. Compared: World ID, the credential and its IDKit integration, against ZOREAL Mark; World App’s other features, the World token and World Chain are out of scope, and World ID for Enterprise’s Zoom and Docusign integrations appear as examples of where a proof is shown.

Where ZOREAL Mark and World ID differ

  • One of a kind

    ZOREAL Mark is one of a kind: the only product of its kind, and the leading product in the market.

  • A platform integration, or none

    A World ID proof is requested by the platform through IDKit and verified on the platform’s backend at World’s verify endpoint, which stores a nullifier to prevent reuse; the verified human badge on Tinder is Tinder’s. A ZOREAL Mark is pasted into any text box, verified by the reader through the extension, the public record or the open-source library, and the platform has to preserve the markers, nothing more.

  • An action, or a text

    A World ID proof is scoped to an app and an action, so the same human cannot act twice in one action, and it carries no content. A Mark record holds the hash of the text and the page URL at the time of signing, and a moved Mark reads "Verified for another page".

  • Anonymous, or named by choice

    World ID is designed to be anonymous: a relying party learns that a unique human is present and nothing about who. A Mark signs, at the holder’s choice per signature, as the platform persona ("A verified human", a pseudonym derived per site and unrelated to any other site) or as the legal name verified against their passport.

Side by side

Comparison of ZOREAL Mark and World ID, from public materials reviewed on 11 September 2026.

AttributeZOREAL MarkWorld ID
What is provenA Mark asserts exactly four things: a human verified by ZOREAL vouched for this text; a live human was present when it was signed, at the stated grade (recent or live); it was signed for this page; and it was signed at this time. It does not assert that the human wrote the text, that the text is true, that the persona is one person across sites, that the person consented freely, or anything about the platform account that posted it. The holder chooses, per signature, which identity signs: the platform persona ("A verified human", a pseudonym derived per site, the same on every page of that site and unrelated to any other site), the legal name ("[Legal Name], verified against their passport"), or, for a company, the organisation (a verified legal person signs as itself, activated by one of its authorised people, who is recorded in the organisation’s own audit log and never published)."an anonymous proof that the user is a unique, live human" (the Orb credential), or that a unique government document is behind the action (the NFC credential), once per action per app, with no identity revealed.
EnrolmentA content-signing certificate issued after ZOREAL verified the person: the government document and its chip, the face against that document, a liveness capture. The key never leaves the secure element and is unlocked with a biometric for each Mark.Proof of Human: verification at an Orb, "a device that captures iris biometrics", valid for 3 years, with Sybil resistance stated. NFC Credential: "a unique government-issued document, such as a passport or eID", where "each document can only be used with one World ID". Selfie Check (beta): a liveness and uniqueness signal from a selfie flow.
Who the mark namesA mark can stand as vouched for by a verified human, carry your name, or carry your role: a president, a principal of a government agency, whatever you are.No one, by design: World ID lets a person "prove you are a unique human without sharing your personal information", with no name, birthdate or address entered.
Content bindingThe record holds the hash of the text and the page URL at the time of signing, and a verifier compares the recorded URL with the page it is on. A moved Mark reads "Verified for another page", an altered one "Not verified".None stated: a proof is scoped to an app and an action, and the nullifier is "A unique identifier for a combination of a user, app_id, and action".
Reader verificationBy anyone, without an account: the browser extension, the public record, or the open-source verifier library against two pinned ZOREAL roots; a moved Mark reads "Verified for another page", an altered one "Not verified"The integrating platform: IDKit returns the proof and the platform’s backend forwards it to World’s verify endpoint, storing the nullifier; the badge a reader sees (Tinder’s "a verified human badge") is the platform’s. A reader-side verification path outside the platform is not stated in the documentation we read.
PricingIt is free to mark content and free to verify a mark. Signing and verifying are free and unlimited on every plan, with no quota: "Sign and verify with ZOREAL Mark: Free, unlimited" on Free and Premium. The pricing page lists Mark as "Coming soon" and says "ZOREAL Mark will be free and unlimited for signing and verifying when it launches." Current prices are on the ZOREAL price list at zoreal.com/pricing."It’s free to join" for individuals (world.org/faqs). For developers, no fee, quota, rate limit or price is stated in the documentation index, the IDKit guide, the 4.0 migration guide or the Developer Portal landing page we read. World ID for Enterprise: no published price list as of September 2026; a contact form at world.org/solutions.
Where it worksMark is platform independent. Any type of content can be marked, on any site.World App on iOS and Android; IDKit for JavaScript, React, Swift, Kotlin and Go; Mini Apps inside World App; on-chain verification. Shown on platforms that integrate it: Tinder’s verified human badge (Japan, expanding to the United States, July 2026), Razer, Zoom and Docusign.
Data handlingZOREAL never sees the text: the extension sends the hash and the URL, and the text reaches the phone sealed under a key that lives only in the QR code. The public record holds a hash of the text, the URL, a per-site persona or the legal name, a timestamp and the signatures; records are immutable and cacheable. A persona is derived per site and is unrelated to the persona on any other site. A legal-name Mark is public and permanent, stated to the holder before the first one and repeated on every one. A holder can withdraw a Mark, which marks the record withdrawn and unpublishes nothing. The extension fetches records without credentials and the record service keeps no per-fetch log beyond aggregate counts, stated as a policy."No data from your World ID verification is stored on the Orb"; images are deleted from the Orb after encrypted transfer to the user’s device; a relying party receives "a cryptographic attestation that you are a real, unique human", and World states "your actions are not trackable through World ID".
CertificationsOrganization-level, as zoreal.com lists them for Bynn Intelligence, Inc.: SOC 2 (attestation), PCI DSS (SAQ A), GDPR (data protection), ISO/IEC 27001:2022 (information security certification) and CSA STAR Level One (cloud security self-assessment). No Mark-specific certification is stated on zoreal.com as of September 2026, and no surface describes a Mark as a qualified or certified signature.Not stated in the public materials we reviewed (world.org product, solutions and FAQ pages, the documentation index and the credential pages).

Where ZOREAL Mark and World ID agree

Both are free to the individual and pseudonymous by default. World ID is free to join and designed so that a relying party learns nothing beyond the proof; a ZOREAL Mark signs as a per-site persona unless the holder chooses their legal name, and the persona on one site is unrelated to the persona on any other.

Both are cryptographic proofs rather than a platform’s say-so, with a stated basis for one person, one identity. World scopes each proof to an app and an action with a nullifier so a human cannot act twice; ZOREAL derives one persona per site, the same on every page of that site. Both let a government document with a chip stand behind the credential: World’s NFC credential binds one document to one World ID, and a ZOREAL enrolment reads the document’s chip and matches the face against it.

Both state plainly what the proof does not carry. World’s proof reveals nothing about who the person is; a Mark does not assert that the human wrote the text, that it is true, or that the persona is one person across sites.

ZOREAL Mark may fit you if

  • You want to stand behind a specific text on a specific page, with the hash and the page URL in the record
  • You want the reader to verify with no platform integration, through the extension, the public record or the open-source library
  • You want the choice, per signature, of a per-site persona or your legal name verified against your passport
  • You want a live-human presence grade on each signature

World ID may fit you if

  • You run a platform and want one-account-per-person Sybil resistance with no identity data
  • You want a verified-human badge on profiles the way Tinder and Razer show it
  • You need a proof-of-human check inside Zoom meetings or Docusign flows
  • Your users already hold World ID, which World states nearly 18 million people have verified at an Orb
