How a Dream Became the Global NFT Digital Credential Platform
In a world of constant transformation, where traditional degrees are no longer enough and learning paths are increasingly diverse, POK Proof of Knowledge was born with a powerful vision: to redefine the value of knowledge through verifiable digital credentials.
But POK is not just another badge platform. From day one, it was designed as a solution based on NFTs (Non-Fungible Tokens), because its founders understood something essential: the future of education needs credentials that are authentic, tamper-proof, transferable, and eternal.
🧠 Why NFT? And What Makes POK Different?
“When we designed POK, we knew NFTs were the most powerful way to protect the value of knowledge. An NFT credential lives on the blockchain, it’s tamper-proof, and it belongs to the student forever.”
— Guido Grinbaum, Co-founder & Chairman of POK
An NFT (Non-Fungible Token) is a unique type of digital asset, registered on a public blockchain (such as Ethereum or Polygon). This allows every credential issued on POK to provide:
- True ownership (it belongs to the holder, not the institution),
- Guaranteed authenticity (it cannot be forged),
- Global interoperability (it can be verified anywhere in the world),
- Eternal persistence (it doesn’t depend on the platform’s survival).
Unlike a “web-based credential” stored in a centralized database (and at risk of being altered or lost if the company shuts down), an NFT credential is decentralized, auditable, and truly yours.
🌐 When Nobody Understood NFTs… We Adapted
“At the beginning, many institutions didn’t understand the advantages of using NFTs. So we created a web-based version, identical to other providers like Credly, Accredible, Certifier, Badgr, Acreditta, or Sertifier. But with one big difference: we offered it completely free.”
— Tomas Mindlin, Co-founder & CEO
This strategic decision allowed hundreds of universities and companies to experience POK without friction and later discover the real power of NFTs. Today, many of them have upgraded, realizing this is not about aesthetics but about user value and ownership.
🏁 A Massive Platform, Not a Niche Tool
“From the start, we decided not to be a tool for ‘early adopters.’ POK was created to scale globally, to be used by millions of people, without entry barriers or tech friction.”
— Silvina Valdez, Co-founder & Chief Strategy Officer
While other platforms position themselves in niche segments (elite universities, bootcamps, corporate HR), POK was designed for all types of organizations: from governments to high schools, from NGOs to online learning platforms.
POK also enables white-label credentials, meaning fully branded for each institution. All with an intuitive interface, open API, OpenBadge 3.0 compliance, European Learning Model, W3C Verifiable Credentials, and global standards.
🧭 And When Everyone Copies… POK Will Already Be Years Ahead
“We know others will end up copying our NFT approach. But we are not here to imitate: we are here to lead.”
— Roy Berman, Co-founder & CEO Spanish Latam
In EdTech, innovation is quickly imitated. But POK moves with vision: integrating NFTs, global standards, employability analytics, and educational marketing — all in one ecosystem.
That’s why more than 1,000 institutions in 20+ countries have already chosen POK, including universities, governments, multilateral organizations, and major corporations.
📍 From the Global South to Global Reach
POK’s journey began in Argentina and Uruguay, expanded in 2023 to Chile, Mexico, and Brazil, and soon after to the rest of Latin America and Spain. In 2024, it began a soft landing in the United States, and by the second half of 2025, it is deploying a strong presence with a 12-person team in California, New York, Miami, and Chicago.
“This team is opening universities every week. The reception is spectacular. What they value most is our simplicity, technical strength, and the NFT model. They see us as a modern, global, reliable alternative.”
— Larry Daniels, Co-founder & CEO Mex & USA
🌟 A Team with a Shared Vision
“Our dream is for POK to be the passport of knowledge for millions of people. That a young person in Peru, an executive in New York, or a student in India can proudly show their learning history with NFT credentials issued by POK.”
— Micaela Lezica, Co-founder & CPO
Because ultimately, knowledge is the currency of the 21st century. But for it to have value, it must be visible, verifiable, and portable.
🔮 Conclusion: The Future Is Already Here, and It’s Called POK
In a world where knowledge evolves faster than ever, NFT digital credentials are not a trend — they are a necessity. The job market, universities, companies, and individuals demand safer, more transparent, and global tools to validate what they know and what they can do.
POK was born with that mission. Not to follow the trend, but to lead it. From Latin America to the world, building an accessible, powerful platform ready to scale across continents.
“The future of education will not revolve around degrees, but around evidence. And we want POK to be the platform where each person builds and showcases their formative, professional, and human identity.”
— Guido Grinbaum, Chairman of POK
What’s coming is an ecosystem of continuous, multidisciplinary, and distributed learning. A world where accumulating credentials is as important as having a strong résumé. A world where what you know will be in your hands, in your wallet — ready to be shared, verified, and celebrated.
And there POK will be: a startup turned global infrastructure, helping millions of people show who they are, what they know, and what they can achieve.
