With POK Wallet App your institution delivers not just a certificate, but a digital asset with identity, value, and global portability.

Learning Paths with POK: Connect Microcredentials and Boost Professional Development

Learning Paths with POK: Connect Microcredentials and Boost Professional Development

POK enables universities and companies to design structured learning paths that connect microcredentials and digital certificates in a coherent educational journey. Each milestone is validated with a verifiable digital microcredential issued on public blockchain, and upon completing all modules, the student receives a final credential recognizing the full set of acquired skills.

What is a Learning Path?

A Learning Path is a structured training journey composed of different courses, workshops, or learning experiences. Each milestone is validated with a verifiable digital microcredential, and upon completing all modules, the student receives a final credential recognizing the full set of acquired skills.

Why implement Learning Paths with POK?

POK’s learning paths integrate natively with Moodle, Open edX, D2L Brightspace, and Blackboard, are compatible with Open Badges 3.0, and allow full customization with institutional branding. Each microcredential and the final credential are recorded on public blockchain, ensuring authenticity and permanent ownership. Institutions can monitor each student’s progress with real-time metrics and communicate the impact of their programs with verifiable data.

With POK, your Learning Paths are not just a training journey but a certified, measurable, and high-impact experience that boosts your institution’s reputation and your students’ professional future.

POK + IEE Equivalency: Global Academic Recognition

POK integrates with IEE Equivalency (International Education Evaluations), an official NACES member, to connect blockchain-based digital credentials with official academic evaluations recognized in the United States. Universities can issue digital credentials with POK while their students directly request U.S. academic equivalency evaluations through IEE.

This integration turns a digital credential into globally recognized academic value — from the blockchain to U.S. institutional verification, with authenticity, transparency, and global mobility for every student.

POK Integrations: Moodle, Blackboard, Salesforce, API and more

POK integrates natively with the leading learning management systems and corporate platforms: Moodle, Blackboard, D2L Brightspace, Open edX, Salesforce, Canvas and more. LTI integrations allow credentials to be issued automatically upon course completion, with no manual intervention and no additional integration costs.

For institutions with specific needs, POK offers a documented API that fully automates the credential issuance, query and revocation workflow. POK's API-first architecture ensures that any institutional system can connect with minimal development resources and without dependency on specialized technical teams.

Bulk Digital Credential Issuance: Simple, Fast and Unlimited

POK allows institutions to issue digital credentials in bulk to hundreds or thousands of recipients in a single process, with no user limit and no additional cost on the free plan. Institutions can upload recipient data via an Excel or CSV file, configure the credential design with their institutional branding and issue in seconds — with no technical team and no complex setup.

For more advanced workflows, POK offers automated issuance via API and automatic issuance integrated with LMS via LTI, allowing credentials to be issued directly upon course or program completion without manual intervention. Institutions can also schedule credential issuance in advance, setting the exact delivery date and time.

Frequently asked questions

POK offers two credential issuance modalities that can be used independently or combined:

Free Web2 version:
  • 100% free with no user caps, no setup costs, and no expiration
  • Credentials are verified via a unique link or QR code on the POK verification portal
  • Fully customizable design with institution branding
  • Compatible with Open Badges 3.0, W3C Verifiable Credentials, and ELM
NFT on public blockchain:
  • Each credential is registered as a unique Non-Fungible Token on Polygon and LacNet — public blockchains
  • Decentralized cryptographic verification — verifiable by anyone, independently, without POK as intermediary
  • Permanent traceability showing when and by whom the credential was issued
  • Recipient owns the credential in their digital wallet, shareable on professional networks
  • Credentials remain verifiable even if POK ceases to operate
Both versions are fully compatible. Institutions can issue Web2 credentials for free and upgrade specific credentials to NFT at any time without reissuing or losing history.

This is one of the most important distinctions in the digital credentials market.

Some platforms claim to use blockchain but actually only generate a cryptographic hash — an alphanumeric fingerprint — and store it on a private server or permissioned network. This is fundamentally different from registering credentials on a public blockchain:

  • A hash alone does not contain the credential or its metadata — only a string that represents it
  • If the server hosting the information disappears or is manipulated, verification breaks entirely
  • A private or permissioned blockchain depends on a central administrator, reducing decentralization and resistance to manipulation
POK NFT credentials use real public blockchain (Polygon and LacNet), where the credential and its verification data are distributed across multiple nodes — with no dependence on any central server, accessible to anyone at any time for independent verification.

The distinction matters significantly when evaluating digital credential platforms:

Public blockchain (e.g., Polygon, Ethereum):
  • Open network where anyone can read and verify records independently
  • Data distributed across thousands of nodes — maximum resistance to manipulation
  • Credential verification does not depend on any single organization remaining operational
Private or permissioned blockchain:
  • Managed by an organization or consortium controlling who can access and record information
  • Faster and cheaper to operate, but depends on a central administrator
  • If the administrator disappears or restricts access, credential verification may be compromised
POK uses public blockchain for its NFT credentials, ensuring that verification is transparent, decentralized, and accessible to any third party globally — without requiring permission from POK or any other intermediary.

POK is aligned with the most relevant global standards for digital credentials:

  • Open Badges 3.0 — the most widely adopted open standard for digital badges and microcredentials, managed by 1EdTech
  • W3C Verifiable Credentials — the internationally recognized data model for verifiable digital credentials, ensuring interoperability across platforms and systems
  • European Learning Model (ELM/Europass) — the European framework ensuring interoperability in education and employment, enabling credential recognition across Europe
  • 1EdTech TrustEd Credentials Framework — independently verified standards for data privacy, interoperability, and credential portability
Compliance with these standards means credentials issued with POK can be integrated and verified on other platforms, LMS systems, and job boards globally — ensuring they will not become obsolete or tied to a single provider.

POK is designed to connect with the tools institutions and companies already use, eliminating manual processes and ensuring real-time data accuracy.

Education (LMS):
  • Moodle, Canvas, Blackboard, Brightspace (D2L), Google Classroom, Open edX
  • Any LMS compatible with LTI (Learning Tools Interoperability) standard
Corporate and HR systems:
  • Workday, SAP SuccessFactors, Oracle HCM, BambooHR, Greenhouse
CRM and marketing:
  • Salesforce, HubSpot, Zoho
  • Google Ads integration for advanced remarketing campaigns using credential engagement data
POK also offers a full REST API and webhooks for custom integrations with internal academic, government, or business management systems.

The result: automatic credential issuance triggered when a student passes a course, completes a program, or meets defined criteria — with no manual intervention required.

Open Badges 2.0 was the reference standard for digital credentials for years, allowing inclusion of basic metadata about the issuer, recipient, and achievement.

Open Badges 3.0, supported by POK, advances this significantly:
  • Integrates natively with the W3C Verifiable Credentials (VC) model — enabling cryptographic verification of credential authenticity
  • Improves interoperability with professional networks, LMS systems, and government platforms
  • Supports enriched metadata including competency framework alignments, detailed criteria, and supporting evidence
  • Compatible with the European Learning Model (ELM) for cross-border recognition
A credential issued under Open Badges 3.0 is not only richer in information — it has significantly greater integration capacity with current and future platforms, ensuring long-term validity and global portability. POK is 1EdTech certified for its Open Badges 3.0 implementation.

Yes. POK is fully compatible with Europass — the European initiative that facilitates the presentation and verification of skills and qualifications internationally.

Credentials issued with POK can be directly integrated into the Europass profile of the holder, alongside other academic and professional documents. This is enabled through POK's compliance with the European Learning Model (ELM) — the technical framework underpinning Europass interoperability.

This compatibility is essential for:
  • Students and professionals seeking opportunities across Europe
  • Universities with international students or European institutional partnerships
  • Organizations issuing credentials that need to be recognized by employers, universities, and authorities across multiple countries
POK is one of the few digital credential platforms outside Europe to achieve full ELM compatibility, making it the recommended choice for institutions with global credential portability requirements.
