What Are Digital Credentials? Types, Applications, and Why They Are the Future of Academic and Professional Certification

Digital credentials are radically transforming how we recognize, verify, and share educational and professional achievements. From badges to NFT diplomas, this new paradigm addresses the needs of a globalized, digital, and employability-driven world.

In this article, you will discover:

  • What digital credentials are
  • Their main types and differences
  • How they work technically
  • Which international standards they follow
  • What benefits they offer compared to traditional certificates
  • And why platforms like POK are leading this change with innovative and free solutions

What Are Digital Credentials?

Digital credentials are electronic representations of achievements, skills, or degrees earned by a person through an educational institution or company. Unlike paper or PDF documents, these credentials:

  • Are verifiable online
  • Contain structured metadata
  • Can be easily shared on social media and professional platforms
  • Comply with international standards such as Open Badges 3.0, 1EdTech, the European Learning Model (ELM), and Europass

Types of Digital Credentials

Here are the main types of digital credentials, their applications, and their benefits:

1. Digital Badges (Open Badges)

Visual representations of micro-achievements, such as completing modules, workshops, or specific skills. They include metadata about:

  • Issuer name
  • Issue date
  • Criteria for achievement
  • Optional evidence
  • Technical standard: Open Badges 3.0 (developed by 1EdTech)

Common uses:

  • Upskilling and reskilling programs
  • Recognition of soft skills
  • Short workshops in universities or bootcamps

Example: Universidad de Antioquia and Tecnológico de Monterrey use Open Badges to highlight specific skills in short programs.

2. Digital Certificates (Web-based)

These simulate a traditional certificate but with digital verification. They generally do not use blockchain.

Common uses:

  • Corporate certifications
  • Completion of university courses
  • Proof of event attendance

Limitations:

  • Easily replicated if not properly protected
  • Often PDF-based with verification through a URL

Example: Credly, Accredible, and Certifier provide this type of credential, but typically under paid and limited plans.

3. NFT Credentials (like those of POK)

NFT credentials are immutable, unique digital certificates stored on blockchain. They represent the most advanced evolution of credentials.

Features:

  • Do not require a platform for verification
  • Function as unique assets (non-fungible tokens)
  • Enable traceability and portability

Advantages over web-based certificates:

  • Independent of servers or URLs that may disappear
  • Greater security, transparency, and autonomy
  • Future compatibility with digital wallets, skills passports, and Web3 environments

POK (Proof of Knowledge) was the first platform designed from day one with this NFT logic, anticipating a decentralized world where credentials are not dependent on centralized providers. However, when launched, many universities did not yet understand the difference from web-based certificates. That’s why POK decided to also offer identical web-based credentials—but 100% free and unlimited. This decision accelerated understanding of the NFT model and showcased POK’s technical superiority.

Quick comparison:

When comparing NFT credentials (like those from POK) versus traditional web-based credentials (such as those from Credly or Accredible), the differences are clear:

  • Verifiable without a platform: NFT (POK) ✅ | Web-based ❌
  • Cost per issuance: NFT (POK) Free ✅ | Web-based Paid ❌
  • Immutable on blockchain: NFT (POK) ✅ | Web-based ❌
  • Globally accessible: NFT (POK) ✅ | Web-based ✅
  • Standards compliance (OB, 1EdTech, ELM): NFT (POK) ✅ | Web-based ✅
  • Free & unlimited issuance: NFT (POK) ✅ | Web-based ❌

This shows how NFTs, especially through POK, offer permanence, verifiability, and scalability at no cost.

4. Digital Diplomas and Professional Degrees

The equivalent of traditional diplomas but digitally validated. They can be issued as verifiable PDFs, advanced Open Badges, or directly as NFTs.

Benefits:

  • Prevent forgery
  • Easily integrated into digital CVs
  • Simplify international procedures (via ELM and Europass frameworks)

How Do Digital Credentials Work?

A digital credential includes:

  • Structured metadata: holder’s name, course, duration, institution, date, level of achievement.
  • Online verification: via QR code, URL, or directly on blockchain.
  • Interoperability: if aligned with Open Badges 3.0, ELM, or other open standards, it can be used across platforms.
  • Social sharing: credentials can be posted on LinkedIn, resumes, emails, or wallets.

International Standards

Leading platforms like POK comply with:

  • Open Badges 3.0: the most advanced standard for interoperable microcredentials.
  • 1EdTech (formerly IMS Global): defines technical specifications for integration and verification.
  • European Learning Model (ELM): defines semantic fields for qualifications and competencies.
  • Europass: the European standard for digital CVs and academic credentials.

Use Cases

Education

  • Recognition of competencies (UPeace, UBA, EAN, Uninorte)
  • Continuing education (UTEC, ITBA, Udelar)
  • Hybrid programs with universities and bootcamps

Public Sector

  • Workforce inclusion programs
  • Certification of government training programs

Companies

  • Internal training
  • Onboarding and upskilling of teams
  • Partnerships with universities for young talent

Market Platforms Comparison

Market Platforms Comparison

If we analyze the main platforms in the market, we see different approaches to digital credentials:

  • POK: ✅ Issues NFTs, ✅ Free, ✅ Web-based, and complies with standards like Open Badges 3.0, 1EdTech, and ELM.
  • Credly: ❌ Does not issue NFTs, ❌ Not free, ✅ Web-based, and compliant with OB and 1EdTech.
  • Accredible: ❌ No NFTs, ❌ Paid, ✅ Web-based, and compliant with OB and 1EdTech.
  • Certifier: ❌ No NFTs, ❌ Not free, ✅ Web-based, compliant only with OB.
  • Badgr (Canvas): ❌ No NFTs, offers only partial free features, ✅ Web-based, compliant with OB.
  • Bealink: ❌ No NFTs, ❌ Not free, ✅ Web-based, compliant with OB.

From this comparison, POK stands out as the only platform combining NFT technology, free issuance, web-based options, and full compliance with global standards.

Why Does POK Offer Free Credentials?

Because web-based credentials have no real value by themselves—the true value lies in the content they represent. That’s why POK:

  • Created a version identical to other platforms, but 100% free
  • Believes the future is NFT, interoperable, and decentralized
  • Promotes mass adoption with an open vision—not a niche one
  • Adapts to universities, governments, NGOs, bootcamps, and companies

And soon, everyone will follow this model.

Conclusion

Digital credentials are more than modern certificates: they are the infrastructure of the future of learning, employment, and global mobility.

While many platforms exist today, only one combines international standards, NFT technology, free issuance, massive scalability, and a long-term vision: POK.
