NodajiFi = Nodaji + Financing

where Curiosity Meets Financial Freedom

Welcome to NodajiFi, a groundbreaking platform where the fusion of AI, blockchain technology, and cryptocurrency creates a new paradigm in digital engagement and economic empowerment. Here, the act of problem-solving and trading evolves from a cognitive exercise to a pathway for financial growth and independence.

What does "Nodaji (노다지)" mean?

The etymology of Nodajl comes from the end of the Joseon Dynasty around the year 1900, in Unsan, Pyongan-do, which is currently in North Korea, where the United States held a lease on the gold mines from Joseon and operated it. There exists a story that an American manager warned Korean miners away from the discovered gold ore by yelling out “Don’t touch” or “No touch”, and the word “No Touch” was mistakenly understood as “No Daji (노다지),” and they thought it as gold in English. Since then, the word Nodaji has been used as a vein of gold or a bonanza in Korea.

We’re tapping into the ancient essence of Nodaji, an epoch where the quest for knowledge and answers was as exhilarating as discovering gold. Leveraging Generative AI like ChatGPT or GEMINI as our modern-day tool, we transition from the shovels of yesteryears to cutting-edge technology. This allows us to explore further into the vast territories of wisdom and self-evolution. For an in-depth historical context on Nodaji, refer to Arirang TV’s History Trivia (EP.25) Nodaji (노다지).

Tackling the Global Financial Divide

A July 2022 report by the World Bank highlights a critical issue: around 1.4 billion adults globally are excluded from banking services. This group, predominantly comprising women, the less educated, and those in economically disadvantaged regions, particularly rural areas, is often marginalized in the digital economy. This challenge extends beyond cryptocurrency access, encompassing traditional banking hurdles such as high transaction fees and slow transfer processes.

Self-Learning & Self-Study: Navigating the Future of Education


Pandemic Experiences

Pandemic Experiences

During the COVID-19 pandemic, many people were required to study or work from home in compliance with government mandates. This experience has demonstrated that it’s now feasible to pursue education remotely, without the need to physically attend schools.

Internet and Smartphone Accessibility

Internet and Smartphone Accessibility

The widespread availability of Internet services and smartphones has been instrumental in making remote learning possible, allowing education to be accessible from virtually anywhere.

Integration of AI as a Personal Tutor

Integration of AI as a Personal Tutor

If AI technology is widely adopted as a personal tutor, it could significantly shape the future of learning, offering personalized and accessible education tailored to individual needs.

Learning through Solving

“Learning through Solving” is a meaningful and effective educational approach. This concept aligns with experiential learning theories, which emphasize learning through direct experience, problem-solving, and critical thinking.

Active Engagement

Learning through solving problems requires active participation, which can lead to deeper understanding and retention of information. It’s a more engaging method than passive learning, like simply listening to lectures or reading textbooks.

Real-World Application

This approach often involves tackling real-world problems, which helps learners understand the practical application of their knowledge and skills. It bridges the gap between theoretical learning and practical application.

Development of Critical Thinking

Solving problems requires critical thinking and decision-making skills. This approach helps learners develop these essential skills, which are valuable in both academic and professional settings.

Encourages Creativity and Innovation

When learners are tasked with solving problems, they’re often required to think creatively and come up with innovative solutions. This fosters creativity and innovation.

Personalized Learning Experience

Problem-solving can often be tailored to the interests and abilities of the learner, making the learning experience more relevant and personalized.

Prepares for Future Challenges

By focusing on problem-solving, learners are better prepared to face future challenges in their academic and professional lives. It teaches adaptability and resilience.

Boosting Self-Learning: The Power of Rewards and Incentives

Global Usability

The rewards system in our platform is designed to be universally accessible, enabling learners from all corners of the globe to participate and benefit. This global approach ensures that regardless of location, users can earn and utilize rewards seamlessly.

Real Money Equivalence

Real Money Equivalence

Our rewards are not just points or digital tokens with abstract value; they are designed to function like real money. This means users can use their rewards to purchase goods and services, both within and outside our platform, without the need for traditional banking or currency exchange processes.

Stability is key in our rewards system. Unlike many digital currencies that suffer from high volatility, our rewards maintain a stable value. This ensures that users can rely on the rewards they earn today to hold the same value tomorrow, making the system fair and predictable.

Using Cryptocurrency as a Reward System

Using the Conventional Cryptocurrencies?

Limited Financial Inclusion

Limited Financial Inclusion

In many underdeveloped regions, a large segment of the population remains outside the traditional banking system. While cryptocurrencies have the potential to bridge this gap, their current implementation often fails to address the needs of the unbanked. The lack of easy access and user-friendly platforms hinders their ability to participate in the digital economy.

Predominant Focus on Asset Trading

Predominant Focus on Asset Trading

The majority of cryptocurrency activity today revolves around trading on exchanges, treating these digital assets more like stocks or commodities than currencies. This speculative nature overshadows their potential as practical, everyday mediums of exchange, limiting their broader adoption and utility in daily transactions.

Deviation from Original Vision

Deviation from Original Vision

Cryptocurrencies were initially envisioned as decentralized, peer-to-peer forms of money, as outlined by Satoshi Nakamoto. However, this vision has been largely overshadowed by their role as tradable assets. The focus on trading and investment has diverted attention from their potential as functional, accessible currencies for the general public.

Operating on top-tier blockchains

Our NodajiFi app/dapp makes it easy for anyone to earn nodaji$ and nodaji tokens in a blockchain, send and receive it as an alternative to payments with a mobile phone. To meet our requirements, we prudently choose top class blockchains called Algorand and Hedera based on transaction speeds, security, finality, scalability, small carbon footprint, etc. 

To hedge against unexpected risks, our NODAJI$ (NUSD) and NODAJI (NDJ) tokens are minted on these blockchains. If one blockchain is shut down, then we can pay back the tokens with another token with the same value on another blockchain.


Algorand designed by Silvio Micali who is the recipient of the Turing Award (in computer science) and MIT professor is a blockchainbased platform that enables users to securely transfer and store value, build applications, and manage digital assets.

Algorand is designed to be secure and highly scalable, with a consensus protocol that is fast and efficient enough to support the global financial system. The platform is built on a permissionless, fully decentralized, and secure blockchain that enables users to easily create, transfer and manage digital assets. Algorand also features a ProofofStake consensus mechanism, allowing users to earn rewards for their participation in the network.

Initially, we implemented a NODAJIFI tokenomy based on an Algorand Blockchain, and will develop the same tokenomy on a basis of Hedera.


Hedera is a distributed ledger technology (DLT) platform that enables anyone to build secure and fair applications that can be used by millions of users. It provides a secure, fast, and fair infrastructure for developers to create the next generation of decentralized applications.

Hedera is powered by a public and permissionless decentralized ledger and consensus service, allowing anyone to develop and deploy code that interacts with the ledger in a secure and trusted manner.
