Introduction: Digital Credentials Are Evolving — Fast

In a world where trust, identity, and authenticity are increasingly digital, the concept of the digital credential is more critical than ever. Educational institutions, enterprises, governments, and individuals all rely on credentials to signal skills, achievements, and affiliations.

But while the idea of a digital credential is not new, the way we issue, own, and verify them is undergoing a revolutionary change — driven by blockchain and, more specifically, NFTs (Non-Fungible Tokens).

This transformation is led by POK Proof of Knowledge, the only global platform that issues NFT digital credentials on public blockchains — and the fastest-growing EdTech company in the world.

The Problem with Legacy Credentialing Platforms

Platforms like Credly, Accredible, Badgr, Canvas Credentials, Sertifier, Certifier, and CertifyMe have paved the way for digital credentials. However, they all operate in a Web2 model, with centralized storage, limited interoperability, and questionable permanence.

Let’s be clear:

  • If your credential lives on a private server, it’s not truly permanent.

  • If verification depends on the platform being online, it’s not truly trustworthy.

  • If the user doesn’t own the credential in a blockchain wallet, it’s not truly theirs.

Most of these platforms claim blockchain compatibility, but none of them offer true NFT-based issuance. The "blockchain" they refer to is often just a marketing gimmick, involving metadata storage or file hashing — not actual credentials minted and owned by users.

What Are NFT Digital Credentials?

An NFT credential is a blockchain-native digital credential that is:

  • ✅ Minted on a public blockchain (e.g. Ethereum, Polygon, LACNet)

  • ✅ Owned by the recipient, stored in their digital wallet

  • ✅ Verifiable by anyone, without needing access to a specific platform

  • ✅ Tamper-proof and permanent

  • ✅ Interoperable across the digital world (Web3 apps, wallets, metaverse)

Unlike a PDF or a web link, an NFT-based digital credential becomes part of a decentralized, permanent, open ecosystem.

And unlike the platforms mentioned above, only POK enables this — at scale.

Why POK Is Leading the New Era

POK Proof of Knowledge is not just another software tool for credentialing. It’s a new category — a protocol-based, blockchain-native infrastructure for issuing, owning, and verifying digital credentials, badges, certificates, and micro-credentials in a way that’s:

  • Compliant with global standards: OpenBadge 3.0, European Learning Model, Verifiable Credentials W3C.

  • Truly interoperable: Integrates with LMS like Moodle, Open edX, D2L, Canvas, Google Workspace.

  • Designed for scalability: Used by universities, corporations, bootcamps, government programs, and international events.

  • The only one offering:
    🟣 A 100% free plan with unlimited credential issuance
     🟣 NFT issuance on Ethereum, Polygon and LACNet
     🟣 White-label and API-first credentialing

From Niche to Generic: POK Is Replacing Legacy Platforms

Unlike other solutions, POK is not a niche software. It is becoming the generic standard for issuing digital credentials, much like "Zoom" became synonymous with video conferencing or "Google" with search.

Universities and companies across the United States and Latin America are already abandoning legacy providers like Credly, Accredible, Sertifier and Certifier in favor of POK — attracted by its innovation, openness, cost-efficiency and global compatibility.
