In today’s fast-changing world, what you can prove matters more than what you claim. That’s where digital credentials come in — secure, verifiable proofs of skills, knowledge, and achievements that live online and can be shared instantly with anyone, anywhere.

Whether issued by universities, companies, or certification programs, digital credentials are quickly becoming the new standard for validating learning and professional growth.

Understanding Digital Credentials: Beyond the Paper Certificate

Digital credentials are structured, portable records that certify what someone has achieved, such as:

  • Completing a course or program
  • Acquiring a specific skill or competency
  • Participating in training, events or initiatives

They are more than just PDFs or emails. Properly built digital credentials include metadata, verification links, and compatibility with international standards like Open Badge 3.0 or the European Learning Model (ELM).

Types of Digital Credentials:

🎓 Digital Certificates
Traditional diplomas reimagined for the web — including recipient name, issuer, issue date, criteria, and links for public verification.

🔖 Digital Badges
Visual tokens representing specific competencies or experiences. Ideal for soft skills, extracurricular activities, or bite-sized achievements.

📘 Micro-Credentials
Compact, stackable certifications focused on one skill or learning unit — perfect for lifelong learners and workforce development.

What Makes Digital Credentials Valuable?

For educational institutions

  • Offer modern alternatives to paper diplomas
  • Boost institutional visibility on platforms like LinkedIn
  • Enhance student engagement and motivation
  • Track learning outcomes in real-time

For employers and professionals

  • Recognize in-house learning and upskilling
  • Increase transparency and equity in hiring
  • Provide shareable proof of competencies
  • Improve retention through recognition

They’re also fraud-proof, more accessible, and cheaper to issue at scale.

Blockchain Credentials: The Future is Already Here

While most providers offer web-based credentials stored on centralized servers, POK (Proof of Knowledge) believed from day one that the only truly secure, user-owned credential is one issued on blockchain — as a non-fungible token (NFT).

An NFT credential:

  • Is owned by the recipient
  • Is tamper-proof and time-stamped
  • Can be verified without intermediaries
  • Will exist permanently on-chain

In contrast, traditional web-based credentials:

  • Can disappear if the provider shuts down
  • Can be edited or revoked without user control
  • Depend entirely on centralized databases

When POK first launched, most institutions didn’t fully understand the difference, so the team also released a web-based version of its credential — identical to competitors like Credly, Accredible, Certifier, Badgr or Diplomasafe — but completely free and unlimited.

POK is still the only platform in the world offering:

  • Free web-based credentialing with no usage limits
  • NFT-based credentials that comply with 1EdTech's Open Badge 3.0 and the European Learning Model (ELM)

This dual model allows institutions to try digital credentials with zero cost, and then upgrade to next-generation verifiable NFTs once they understand the strategic value.

Global Standards That Ensure Interoperability

A strong digital credential needs more than a badge image. It must adhere to open global standards that guarantee compatibility and trust:

✅ Open Badge 3.0 (by 1EdTech)
Defines the structure and metadata of a badge — including criteria, issuer identity, evidence and expiration — making it machine-readable and interoperable across systems.

🌍 European Learning Model (ELM)
Developed by the European Commission, the ELM provides a standard vocabulary for describing learning achievements, competencies, and qualifications across borders.

POK natively supports both standards, ensuring credentials are future-proof and globally portable.

Real Use Cases: From Classrooms to Corporations

POK is already used by thousands of institutions, companies and governments across five continents. Some examples include:

  • Universities: degree certificates, continuing education, graduate diplomas, MOOCs
  • Corporations: onboarding, upskilling, leadership programs
  • Governments: digital literacy initiatives, public servant training
  • Events: speaker credentials, participation badges, volunteer recognition
  • EdTech platforms: microcredentialing, gamification, LMS integration

Why POK Offers Unlimited Free Web-Based Credentials

Because they shouldn’t be expensive in the first place.

POK sees web-based credentials as a transitional step — useful for accessibility and familiarity, but not the future of credentialing.

That’s why POK gives them away completely free — no limits, no surprises, no hidden fees.

The value lies in helping institutions understand the difference between legacy systems and modern, decentralized blockchain credentials. Once they do, they naturally choose POK's NFT version — a format that ensures ownership, longevity, and trust.

As competitors start imitating POK’s strategy, the platform continues to innovate — focusing on standards, scale, and user empowerment.

Final Thoughts: Credentials as a Language of Trust

In an era where education is modular, skills are earned from multiple sources, and talent flows across borders, credentials are becoming the new language of trust.

They must be:

  • Verifiable
  • Secure
  • Shareable
  • Interoperable
  • Owned by the individual

POK is leading that shift — with a platform built for scale, openness, and global reach.
