NFTs beyond the hype - Solving real-world problems

Arjan van Eersel — Fri, 09 Aug 2024 10:17:10 +0000

NFTs, or Non-Fungible Tokens, have garnered a lot of attention for their use in the digital art world, but their potential extends far beyond that. In this article, I'll explain how NFTs are being used to solve real problems.

Tokens 101

Before diving into NFTs, it's helpful to explain what tokens are.

Types of tokens

Tokens can be fungible, non-fungible or a hybrid of both.

Fungible Tokens

Fungible tokens are identical and fully interchangeable. They can be best compared to coins of your local currency. If both of us have one euro and we switch our euros, nothing changes. This is fungibility.

Non-Fungible Tokens (NFTs)

Non-Fungible Tokens (NFTs) are unique and cannot be interchanged on a one-to-one basis. The uniqueness is often represented by a digital object or a physical asset. Digital art is the most well-known example, but NFTs can also represent real estate, with the NFT serving as a digital title deed.

This is the type of token we're focusing on in this article.

Embedded rights

Tokens always have certain embedded rights, which can include:

Usage rights
Access rights
Property rights
Voting rights

Sometimes these rights overlap. For example:

A token representing a share in a company usually includes both a property right (dividend) and a governance right (voting).
A token representing real estate usually embeds a property right (ownership) but can also include a usage right (timesharing).

For now, it's important to understand that tokens have embedded rights. I'll cover this topic in more detail in a future article.

How NFTs are being used

1. Gaming assets and virtual worlds

NFTs are revolutionizing the gaming industry by allowing players to own, trade, and monetize in-game assets. These assets could be anything from characters and skins to weapons and virtual real estate. NFTs provide true ownership, meaning that even if a game shuts down, the assets still belong to the players.

Example: Axie Infinity is a popular play-to-earn game where players collect and breed digital pets called Axies. Each Axie is an NFT that can be traded or sold on various marketplaces. The game has created a vibrant economy where players earn income by participating in the game.

2. Digital identity and credentials

NFTs can serve as verifiable proof of identity or credentials, allowing individuals to maintain control over their personal information while ensuring its authenticity. This has applications in everything from digital passports to educational certificates.

Example: IncentiVerse, a project I founded, is working on decentralized identity solutions that use NFTs to represent verifiable credentials. These NFTs can be used to prove identity, education, professional achievements, and more, without relying on centralized authorities.

3. Real estate

In real estate, NFTs can represent ownership of physical property or shares in a property, enabling fractional ownership, easier transfer of property rights, and more transparent transactions.

Example: Xcavate is a blockchain-based real estate platform that facilitates a modular protocol for tokenizing real estate assets. It’s particularly unique because it independently varifies owner ID, asset attributes and price before an NFT can be minted.

4. Supply chain management

NFTs can be used to track the provenance and authenticity of goods as they move through the supply chain. This is particularly valuable in industries like luxury goods, pharmaceuticals, and food, where verifying the origin and authenticity of products is crucial.

Example: IBM Food Trust is a blockchain-based solution employed by various companies to enhance transparency and traceability in the food supply chain. While primarily using blockchain technology, NFTs are being explored within this ecosystem to represent unique items or batches of goods, providing an immutable record of their journey from farm to table.

5. Ticketing and access control

NFTs can be used for ticketing at events or as access control for digital or physical spaces. This ensures that tickets are unique, easily transferable, and helps in preventing fraud.

Example: YellowHeart is a platform that uses NFTs for ticketing. They have partnered with artists and venues to issue NFT tickets, which can include additional benefits like exclusive content or perks for ticket holders.

6. Intellectual property and royalties

NFTs can represent ownership of intellectual property (IP) and enable automatic royalty payments. This is particularly useful in creative industries where tracking the use of IP and ensuring creators are fairly compensated is often challenging.

Example: Async Art allows artists to create programmable art that can change over time or in response to external events. The art is minted as an NFT, and the platform automates royalty payments to the artist each time the NFT is resold.

7. Charity and social impact

NFTs can be used in fundraising for charities or social causes by providing a digital certificate of donations made or by creating unique digital assets that donors can purchase, with the proceeds going to support specific initiatives.

Example: Trrue is developing a donation crowdfunding module as a part of its system. This module uses NFTs to certify donations. The NFT can be used by donors to generate the documents required by their local tax authority.

8. Music and entertainment

Musicians and entertainers can use NFTs to directly sell their work to fans, bypassing traditional intermediaries. This can include anything from individual songs to concert tickets or exclusive experiences.

Example: Royal is a platform that allows musicians to sell fractional ownership of their songs to fans through NFTs. In return, fans receive a share of the royalties, creating a new way for artists to fund their projects and for fans to invest in music.

9. Healthcare

NFTs can secure sensitive health records, ensuring that individuals maintain control over their personal data while allowing for easy sharing with healthcare providers when necessary.

Example: While still in the early stages, there are experimental EHR Data projects exploring the use of NFTs to tokenize and secure health records. This could empower patients to manage their health data securely and share it with doctors or researchers as needed.

Other (future) use cases of NFTs

The potential for NFTs extends to areas not yet fully explored but holding great promise for the future:

Legal contracts: NFTs could represent legal contracts, simplifying complex legal agreements and ensuring that all parties involved have access to a verifiable, immutable version of the contract.
Tokenized assets and securities: NFTs could represent shares in a company or other financial instruments, enabling more accessible and transparent trading of assets on decentralized platforms.
Government services: NFTs could be used for various government services, such as land registry, vehicle registration, or even voting, ensuring transparency, security, and efficiency while eradicating corruption.

Conclusion

NFTs are far more than just a trend in digital art; they offer a wide range of applications that can solve real-world problems. From revolutionizing industries like gaming and real estate to potentially transforming how we manage identity, intellectual property, and legal contracts, NFTs are poised to become a foundational technology for the digital economy.

As we look beyond the hype, the true value of NFTs lies in their ability to provide verifiable ownership, transparency, and decentralization across a wide range of applications.

Introduction to my journey: From developer to CTO at a startup

Arjan van Eersel — Tue, 06 Aug 2024 07:11:19 +0000

Transitioning from a developer to a Chief Technology Officer (CTO) and startup founder is a path filled with challenges, learning, and immense growth. It's a journey that many in the tech industry aspire to undertake, yet it requires more than just technical expertise.

This article aims to highlight the key challenges and lessons learned from those who have successfully navigated this transition, along with my personal experiences to provide additional insights and context.

The initial steps: Recognizing the need for leadership

The first step in transitioning from a developer to a CTO is recognizing the need for leadership and the willingness to step into that role. As a developer, your primary focus is on coding, problem-solving, and implementing features. However, the CTO role demands a broader perspective, focusing on aligning technology with business goals, managing teams, and strategic planning.

If I look at Trrue, in the very beginning I was only CTO in name, and this is very common with early-stage startups. There is no money yet to hire a development team, and the developer-CTO's main task is to create an MVP as soon as possible so that there's something to show to investors. However, it will change, so use this time wisely to also prepare for the non-technical tasks that are waiting for you.

Developing a strategic vision

One of the key responsibilities of a CTO is to develop and communicate a strategic vision for the company's technology landscape. This involves understanding market trends, customer needs, and how technology can provide a competitive edge.

I would say that the most important lesson is not to think that you know what your client wants. There might be a great idea on the table, but don't be too stubborn about it. Instead, be willing to amend the idea and implementation to meet the needs of clients. For this reason, I can only encourage releasing software as soon as possible and starting testing with potential clients, even if the software still contains many bugs. The goal of the exercise is to test functionality and whether you're actually solving things for clients.

Lessons from others:

Drew Houston (Dropbox): Houston emphasized the importance of aligning the technology roadmap with the company's mission and customer needs. He learned to balance long-term vision with short-term goals.
Susan Wojcicki (YouTube): Wojcicki highlighted the need for constant innovation and adapting to changes in the tech landscape. She stresses the importance of being open to new ideas and pivoting when necessary.

Building and leading teams

Transitioning to a CTO role means shifting from individual contributions to leading and inspiring teams. Effective team leadership involves recruiting the right talent, fostering a collaborative environment, and providing guidance and mentorship.

Trrue is now at the point that it will start hiring developers very soon. Reaching this point took a lot of preparation, particularly because we took our time to discover the right technology stack in combination with how our product's architecture changed due to experiences with our MVP and further market research. I have written an earlier article about how I came to Trrue's earlier technology stack, which you can read here: [https://ave.cy/blog/choosing-a-tech-stack/]

One important conclusion from my previous article is that picking a technology stack also includes the availability of the developers we need, as well as being willing to train developers from other languages to adapt to less common languages. The biggest part of our backend is written in the Rust programming language, and finding good Rust developers, especially those who also know Polkadot's Substrate, is a challenge.

Lessons from others:

Elon Musk (Tesla, SpaceX): Musk is known for his hands-on approach and high standards. He believes in hiring talented individuals who are passionate about their work and pushing them to achieve their best.
Sheryl Sandberg (Facebook): Sandberg advocates for strong communication and building a culture of trust and respect. She emphasizes the importance of listening to team members and valuing their input.

Managing the transition from developer to leader

For many developers, the transition to a leadership role can be daunting. It involves stepping out of your comfort zone, developing new skills, and embracing a different mindset.

I can say that my previous experience as a consultant in the corporate services sector has helped me focus on strategic decision-making and team management. Nevertheless, I did go through a few business and management courses to freshen up knowledge and fill in any gaps. As a big proponent of lifelong learning, I will continue to improve my knowledge and learn new skills, because there will always be room for improvement.

I also had the honor of participating in the Berkeley cohort of the Polkadot Blockchain Academy in 2023. The PBA offered a founder and developer track, and I went for the developer track. Perhaps that sounds contradictory to what I've written so far about transitioning to management tasks; however, I still find it very important to really understand the process of developing on Substrate. Doing the developer track really helped me with my task of composing the development team. Additionally, the Polkadot Blockchain Academy is a versatile program, and even the developer track goes way beyond just development. It also teaches topics like governance and blockchain economics, which are crucial pillars of any blockchain-based architecture. The knowledge gained at the PBA has therefore helped me tremendously to finalize TrrueChain's architecture.

Lessons from others:

Marissa Mayer (Yahoo!): Mayer spoke about the challenges of shifting from a technical role to a managerial position. She learned to delegate effectively and trust her team to handle the technical details.
Satya Nadella (Microsoft): Nadella's journey emphasized the importance of continuous learning and personal growth. He adopted a growth mindset and encouraged his team to do the same.

Balancing technical expertise with business acumen

A successful CTO must balance technical expertise with business acumen. This involves understanding the financial implications of technology decisions, working closely with other departments, and contributing to overall business strategy.

I took the initiative to learn more about business operations and finance. This helped me make informed decisions that aligned with both our technological capabilities and business goals. Trrue is a regulated company, so it's also important to understand where the functionality of our product will be affected by regulations. The software that our development team produces will have to comply with these regulatory requirements, and the development processes must be ready for regulatory changes. Additionally, being regulated increases scrutiny on the reliability of the software.

Lessons from others:

Jeff Lawson (Twilio): Lawson emphasized the importance of understanding both technology and business. He learned to speak the language of both engineers and executives, bridging the gap between the two.
Ginni Rometty (IBM): Rometty highlighted the need for a deep understanding of the market and the ability to make strategic decisions that drive business growth.

Embracing continuous learning and adaptability

The tech industry is constantly evolving, and a successful CTO must embrace continuous learning and adaptability. Staying updated with the latest trends, technologies, and best practices is crucial.

I am very committed to continuous learning. Although I'm very picky about conferences, I do attend industry conferences, participate in webinars, and read extensively about emerging technologies and business strategies.

Lessons from others:

Bill Gates (Microsoft): Gates is known for his lifelong learning approach. He dedicates time to reading and staying informed about various fields, which helps him stay ahead in the tech industry.
Jack Dorsey (Twitter, Square): Dorsey emphasizes the importance of being adaptable and open to change. He believes in iterating and improving constantly.

Conclusion

The journey from developer to CTO and entrepreneur is challenging but immensely rewarding. It requires a shift in mindset, the development of new skills, and a commitment to continuous learning and growth. By studying the experiences of successful tech leaders and integrating these lessons with your own experiences, you can navigate this transition effectively and lead your team to new heights.

Let's connect

If you're a developer aspiring to move into a leadership role, start by setting clear goals, building your leadership skills, and embracing continuous learning. And remember, the journey is as important as the destination.

I hope my story and the lessons shared here inspire you to take the leap and pursue your own path to leadership. Feel free to reach out to me with your thoughts or experiences.

Using Blockchain for Education: Transforming Learning with Technology

Blockchain technology is transforming various industries, and education is no exception. From enhancing transparency and security to decentralizing the learning process, blockchain offers a myriad of possibilities for traditional and fully decentralized education systems.

Blockchain in Traditional Education

Enhancing Credential Verification

One of the most promising applications of blockchain in traditional education is the verification of credentials. Educational institutions can issue diplomas, certificates, and transcripts on a blockchain, ensuring they are tamper-proof and easily verifiable by employers, other institutions, and individuals.

By storing educational credentials on a blockchain, we can effectively eliminate the risk of counterfeit diplomas and transcripts. Every credential is associated with a unique hash on the blockchain, providing a secure and transparent way to verify authenticity.

Example: The Massachusetts Institute of Technology (MIT) has piloted a project to issue digital diplomas on a blockchain, allowing graduates to share verifiable credentials with potential employers.

Streamlining Administration

Blockchain technology can also streamline administrative processes in educational institutions, from admissions to record-keeping and beyond. By creating a decentralized ledger, schools and universities can ensure that data is secure, accurate, and accessible only to authorized individuals.

Efficient Record-Keeping: Blockchain allows for the creation of immutable records, reducing the chances of errors and discrepancies in student records.

Improved Transparency: Parents, students, and educators can have access to real-time updates on academic progress, attendance, and other vital information.

Blockchain technology enables the creation of decentralized learning platforms, where students and educators can interact directly without intermediaries. This approach democratizes access to education, allowing learners from around the world to access high-quality resources and courses.

Open Access: Decentralized platforms can offer open access to educational content, breaking down geographical and financial barriers that traditionally limit learning opportunities.

Peer-to-Peer Learning: Students can learn from each other and collaborate on projects, facilitated by smart contracts that ensure fair distribution of rewards and credits.

Revolutionizing Education Credentials

One of my projects, IncentiVerse, leverages blockchain to create live NFTs (Non-Fungible Tokens) and self-sovereign identity for education credentials. Unlike traditional NFTs, live NFTs are dynamic and can change based on the holder's ongoing educational achievements, ensuring that credentials remain up-to-date and reflect a person's current skills and qualifications.

Combating Diploma Mills and Fraud

Blockchain's Role in Ensuring Authenticity

Diploma mills and fraudulent credentials are significant problems in the education sector. Blockchain offers a robust solution to these challenges by providing an immutable and transparent way to verify educational credentials.

Immutable Records: Once a credential is recorded on the blockchain, it cannot be altered or tampered with, ensuring its authenticity and integrity.

Real-Time Verification: Employers and other institutions can quickly verify credentials in real time, reducing the risk of hiring unqualified individuals.

Example Projects and Initiatives

Several projects and initiatives are utilizing blockchain to combat diploma mills and fraud, including Blockcerts, an open standard for blockchain-based certificates, and Learning Machine (now Hyland), a company working with educational institutions to implement blockchain-based credentialing solutions.

Token Engineering of Education Projects

Understanding Token Engineering

Token Engineering provides a structured framework to address the challenges of creating sustainable, efficient, and fair systems in the blockchain space. It ensures that tokenomics is designed with a clear understanding of its potential impact on user behavior and system dynamics.

Good Token Engineering Practices

When applying token engineering to education, several best practices should be considered, including aligning tokens with educational goals, designing effective economic incentives, and integrating various aspects such as economics, business, governance, technical, and legal.

Implementing Tokenomics in Education

Tokenomics can play a vital role in education by creating innovative reward systems and driving engagement, such as rewarding learning achievements, facilitating collaboration, and supporting decentralized education platforms.

Conclusion
