NFTs - A hype or a lasting new investment asset class?


NFTs are at the moment a real buzz. The word NFT stands for non-fungible token, which means a unique, irreplaceable cryptographic object. It aims to manage ownership of digital content (digital collectible items) by storing the ownership in the form of a digital certificate on a blockchain (usually on the Ethereum blockchain, but other blockchains can also be used). This way the buyer can prove that he is the owner of a certain digital item.

The fact that the NFT token is unique and irreplaceable, generates traceability of the owner, but also ensures authenticity and (digital) scarcity, thus resulting in its value (via its uniqueness it becomes a collectible item).
This makes it an attractive asset for both buyers and sellers. For sellers, creating (= minting) an NFT gives an easy option to monetize (without intermediaries like galleries or auction houses) their digital content (products), like digital pictures, animations, music, videos…​. Additionally NFTs have the feature that the author can also get a percentage of future transaction amounts (thus profiting of a future increase in value of the NFT).
The buyer can invest in digital art and can be sure of the uniqueness and his ownership (i.e. the bragging right that you own the art) and the ownership can easily be transferred to any other buyer in the world (becoming the new owner) with the click of a button.

NFTs started in 2017 with CryptoKitties (a game to breed and trade digital kittens) and CryptoPunks and gradually increased over the last years, but it exploded in 2021 (i.e. in 2020 the market was estimated to $250 million over the whole year, while in the month of February 2021 alone already $360 million of NFTs were traded), with some record transactions, like:

  • The record is held by the digital composite called "EVERYDAYS: The First 5000 Days" (see picture of this blog) of the digital artist "Beeple" (Mike Winklemann), which was sold at Christie’s for $69.3 million. Of the same artist also a video was sold for $6.6 million.

  • Christie’s auctioned recently also an NFT of 9 virtual rare CryptoPunks for a record amount of $16.9 million

  • The first tweet on Twitter of the co-founder and CEO of Twitter Jack Dorsey was sold for just under $3 million

  • The Canadian singer-songwriter Grimes (also known as the partner of Elon Musk) sold for around $6 million of digital artworks, including an NFT of about $400.000 for a 50-second video.

  • NBA’s Top Shot has generated more than $230 million in selling NFTs of NBA highlight videos, with a top transaction for a movie of Lebron James dunking, which was bought for over $200.000. These NFTs have become the digital equivalent of the paper sports collection cards.

While those transactions get the news headlines for their record amounts, thousands of NFTs are also sold for a few thousand euros. E.g. a selfie of Lindsey Lohan was sold for $59.000, Bad Luck Brian yearbook photo for $36.000 or the "Charlie bit my finger!" YouTube clip was sold for $761.000, not to mention the thousands of transactions that do not get any media attention at all.

These enormous prices definitely attract a lot of media attention and investors, but nonetheless NFTs remain difficult to grasp. While for traditional art, the owner has the physical artwork in his possession, this is not the case at all for NFTs. For example, the NFT for the Beeple picture sold for the record amount can perfectly be downloaded on the internet at no cost. This downloaded file will be identical to the digital file owned by the buyer (i.e. the copy is literally as good as the original).

Obviously, this is a new technology which raises a lot of questions and issues, e.g.

  • What do you actually own? The NFT is just a digital certificate on a blockchain. The blockchain does not even contain the digital artwork, but just a link to a location where the digital artwork is stored. This raises automatically questions like:

    • What is the legal ground of an NFT? Can you claim the ownership in court, i.e. will the courts consider the blockchain as sufficient proof of ownership? Will the judge even understand it? Will it have the same legal basis in any country in the world? Can I win at court if someone exploits commercially the digital content owned by me?

    • What happens if the link to which the NFT refers is no longer available? Does the NFT lose its value? Can the link be adapted?

    • What is the exact digital asset I am owning? On the blockchain a hash of the digital asset, together with some ownership info, is stored. However if someone changes 1 (invisible) pixel to a digital artwork, the hash will no longer match. Do I also have the ownership of this new (nearly equivalent) digital artwork?

    • How transparent and well-defined are the properties of ownership? E.g. do you also buy the copyright and reproduction rights? Are you allowed to ask royalties if the digital item is downloaded/published? Are you allowed to ask BigTechs (like Facebook or Google) to remove all copies they store of your digital asset?

  • NFTs are typically sold via intermediate platform (like OpenSea, Rarible, Superrare, Foundation, AtomicHub, Nifty Gateway, KnownOrigin…​), managing the contact with the artist, setting up the NFT, managing the transactions on the Blockchain and also storing the digital artwork in the cloud (i.e. location to which NFT refers). This raises a number of questions about the trustworthiness of those platforms:

    • Will they ensure the link to the artwork remains available (i.e. not lost or broken)? Even if they go bankrupt? More and more decentral IPFS network or blockchain based storage is used to mitigate this risk.

    • Does the platform ensure an artist does not create multiple NFTs of the same (or slightly changed) digital asset?

    • Do they ensure that the NFS is minted by the real artist (creator) of the content and not by an imposter? Which procedures do they have in place for verifying that?

    • Even though the decentralized nature of the underlying blockchain ensures trust, buyers and sellers still need to trust the platforms facilitating these NFT transactions. This is for me a general issue of blockchain use cases (cfr. my blog on blockchain "ttps://bankloch.blogspot.com/2020/02/blockchain-beyond-hype.html" - Blockchain - Beyond the hype), i.e. although the blockchain entry can be perfectly trusted, the end-to-end user journey is much more extensive, thus requiring still trust in a central party.

  • How future-proof are the blockchains? With blockchains in full evolution, will the Ethereum blockchain (or other blockchain on which an NFT is held) still be around in 5 years or in 10 years (or not be replaced by a more popular and more modern blockchain)? Will it be possible to keep the decentralized nature of this blockchain while volumes increase enormously? Beginning of June 2021 the Ethereum blocksize (of the full blockchain) was over 800 GB, an increase of more than 100% compared to the year before. This shows that storing the full blockchain (and then we do not even speak about the resources required for mining) has become more and more a specialist job, hence more centralisation and less guarantee that a lot of parties will continue to keep track of the full blockchain. Furthermore it means it becomes less straight forward to prove your NFT ownership, without consulting a specialized party which stores the full blockchain.

  • Is the energy consumption for an NFT sustainable and will it not negatively impact the future success of NFTs?. For example, the energy consumption to create an NFT of a simple animation is equal to using 1.5 million times a pressure cooker. However with blockchains switching more to Proof of Stake-consensus mechanisms this will likely be resolved in the coming years (although Proof of Stake raises naturally other new concerns about centralization and potential manipulation).

  • Are the NFTs currently sold for a lot of money sufficiently time-lasting? This question can be raised for both the digital artworks as for the technology underpinning it:

    • Are the digital artworks not too time-specific, i.e. linked to current, non-lasting hypes? E.g. will YouTube movies which are popular now still be remembered and popular in 5 years? In the traditional art, certain historical artists (like Monet, Van Gogh, Picasso…​) have an established reputation/track record, but for this digital art there is of course no historical records to turn to and as a result it is very difficult to predict future trends.
      NFTs are also more and more used in games, to describe ownership of virtual plots of land or unique weapons or armors. This makes the NFT practically usable, but what is the value in a few years when the game is no longer popular?

    • Is the technology sufficiently robust? Not only is there a risk due to the above-mentioned dependency on blockchains and the platforms for storing the digital asset, but besides that you also have to ensure the file format of the digital content can still be read or ensure you can still access your digital wallet.

  • Due to popularity of the underlying blockchains (like Ethereum), NFTs are confronted with high transaction costs(high gas fees to get your NFT on the blockchain). While this transaction cost is marginal for the above record amount NFTs, it does pose an issue for cheaper NFTs (as transaction cost become too significant compared to the NFT price).

  • The whole process of minting, buying and transferring NFTs is not so user friendly, i.e. you need to onboard on an NFT platform, you have to acquire the right crypto-currency (e.g. if the NFT is on the Ethereum blockchain, you need Ether coins, i.e. Bitcoins won’t be usable) and you have to pay with crypto-currencies, which is still not so user-friendly (i.e. typically via a browser plugin, which might be easy for a computer specialist, but still difficult to setup for the common layman).

Clearly the concept of NFTs is great, as there is a need for managing ownership of digital content. With more and more digital content being produced and some artists even only exclusively producing digital content, there is a need for them to make money and NFTs are a good way to do this. However the too strong focus on the underlying (blockchain) technology and the bullish prices, make it still too much a playground for the (mega)-rich, than a common investment asset class. However even if it remains such a playground, it is still interesting to follow. As there are as many as 100,000 people who have $1 million or more stashed in crypto-currencies, there is an enormous audience with the means, interest and risk appetite to try out NFTs. For them, there is the cool factor of trying out something new, the potential of making same profits as with crypto-currencies, the emotional and bragging aspect of owning digital arts (compared with owning parts of the moon or owning a star. This has no legal ground, but is still very romantic and fun) and the Robinhood aspect of pushing governments to change and fighting the traditional art system (cfr. the actions on Robinhood to stop the short-sellers on the share of GameStop).

This being said, NFTs are clearly an excellent real-live experiment, where fundamental questions around ownership, value, digitalization and authenticity are being addresses.
The question remains however if ownership can be managed outside governments, i.e. as ownership requires laws to protect the owner, it is very difficult to manage this outside a government.
Clearly governments should sponsor some kind of register of such digital ownership. This will ensure that there is legal ground and also long-term continuity, as unlikely governments will disappear/go bankrupt. However if done by a government, there is no real need for a blockchain, as you have a central, credible authority, which could perfectly store the ownership (personal details of the owner) and the full digital content (so not just a hash) in a traditional database.
While governments are starting now to explore an alternative for crypto-currencies in the form of CBDCs (cfr. my blog "https://bankloch.blogspot.com/2021/05/cbdc-new-kid-on-block.html" - CBDC - The new kid on the block), this will likely happen as well for NFTs.

In the meantime, it is good the conservative art world is shaken up by these kinds of innovations.

Transforming the insurance sector to an Open API Ecosystem

1. Introduction "Open" has recently become a new buzzword in the financial services industry, i.e.   open data, open APIs, Open Banking, Open Insurance …​, but what does this new buzzword really mean? "Open" refers to the capability of companies to expose their services to the outside world, so that   external partners or even competitors   can use these services to bring added value to their customers. This trend is made possible by the technological evolution of   open APIs (Application Programming Interfaces), which are the   digital ports making this communication possible. Together companies, interconnected through open APIs, form a true   API ecosystem , offering best-of-breed customer experience, by combining the digital services offered by multiple companies. In the   technology sector   this evolution has been ongoing for multiple years (think about the travelling sector, allowing you to book any hotel online). An excelle...

Are product silos in a bank inevitable?

Silo thinking   is often frowned upon in the industry. It is often a synonym for bureaucratic processes and politics and in almost every article describing the threats of new innovative Fintech players on the banking industry, the strong bank product silos are put forward as one of the main blockages why incumbent banks are not able to (quickly) react to the changing customer expectations. Customers want solutions to their problems   and do not want to be bothered about the internal organisation of their bank. Most banks are however organized by product domain (daily banking, investments and lending) and by customer segmentation (retail banking, private banking, SMEs and corporates). This division is reflected both at business and IT side and almost automatically leads to the creation of silos. It is however difficult to reorganize a bank without creating new silos or introducing other types of issues and inefficiencies. An organization is never ideal and needs to take a numbe...

RPA - The miracle solution for incumbent banks to bridge the automation gap with neo-banks?

Hypes and marketing buzz words are strongly present in the IT landscape. Often these are existing concepts, which have evolved technologically and are then renamed to a new term, as if it were a brand new technology or concept. If you want to understand and assess these new trends, it is important to   reduce the concepts to their essence and compare them with existing technologies , e.g. Integration (middleware) software   ensures that 2 separate applications or components can be integrated in an easy way. Of course, there is a huge evolution in the protocols, volumes of exchanged data, scalability, performance…​, but in essence the problem remains the same. Nonetheless, there have been multiple terms for integration software such as ETL, ESB, EAI, SOA, Service Mesh…​ Data storage software   ensures that data is stored in such a way that data is not lost and that there is some kind guaranteed consistency, maximum availability and scalability, easy retrieval...

IoT - Revolution or Evolution in the Financial Services Industry

1. The IoT hype We have all heard about the   "Internet of Things" (IoT)   as this revolutionary new technology, which will radically change our lives. But is it really such a revolution and will it really have an impact on the Financial Services Industry? To refresh our memory, the Internet of Things (IoT) refers to any   object , which is able to   collect data and communicate and share this information (like condition, geolocation…​)   over the internet . This communication will often occur between 2 objects (i.e. not involving any human), which is often referred to as Machine-to-Machine (M2M) communication. Well known examples are home thermostats, home security systems, fitness and health monitors, wearables…​ This all seems futuristic, but   smartphones, tablets and smartwatches   can also be considered as IoT devices. More importantly, beside these futuristic visions of IoT, the smartphone will most likely continue to be the cent...

PSD3: The Next Phase in Europe’s Payment Services Regulation

With the successful rollout of PSD2, the European Union (EU) continues to advance innovation in the payments domain through the anticipated introduction of the   Payment Services Directive 3 (PSD3) . On June 28, 2023, the European Commission published a draft proposal for PSD3 and the   Payment Services Regulation (PSR) . The finalized versions of this directive and associated regulation are expected to be available by late 2024, although some predictions suggest a more likely timeline of Q2 or Q3 2025. Given that member states are typically granted an 18-month transition period, PSD3 is expected to come into effect sometime in 2026. Notably, the Commission has introduced a regulation (PSR) alongside the PSD3 directive, ensuring more harmonization across member states as regulations are immediately effective and do not require national implementation, unlike directives. PSD3 shares the same objectives as PSD2, i.e.   increasing competition in the payments landscape and en...

Trade-offs Are Inevitable in Software Delivery - Remember the CAP Theorem

In the world of financial services, the integrity of data systems is fundamentally reliant on   non-functional requirements (NFRs)   such as reliability and security. Despite their importance, NFRs often receive secondary consideration during project scoping, typically being reduced to a generic checklist aimed more at compliance than at genuine functionality. Regrettably, these initial NFRs are seldom met after delivery, which does not usually prevent deployment to production due to the vague and unrealistic nature of the original specifications. This common scenario results in significant end-user frustration as the system does not perform as expected, often being less stable or slower than anticipated. This situation underscores the need for   better education on how to articulate and define NFRs , i.e. demanding only what is truly necessary and feasible within the given budget. Early and transparent discussions can lead to system architecture being tailored more close...

Low- and No-code platforms - Will IT developers soon be out of a job?

“ The future of coding is no coding at all ” - Chris Wanstrath (CEO at GitHub). Mid May I posted a blog on RPA (Robotic Process Automation -   https://bankloch.blogspot.com/2020/05/rpa-miracle-solution-for-incumbent.html ) on how this technology, promises the world to companies. A very similar story is found with low- and no-code platforms, which also promise that business people, with limited to no knowledge of IT, can create complex business applications. These   platforms originate , just as RPA tools,   from the growing demand for IT developments , while IT cannot keep up with the available capacity. As a result, an enormous gap between IT teams and business demands is created, which is often filled by shadow-IT departments, which extend the IT workforce and create business tools in Excel, Access, WordPress…​ Unfortunately these tools built in shadow-IT departments arrive very soon at their limits, as they don’t support the required non-functional requirements (like h...

An overview of 1-year blogging

Last week I published my   60th post   on my blog called   Bankloch   (a reference to "Banking" and my family name). The past year, I have published a blog on a weekly basis, providing my humble personal vision on the topics of Fintech, IT software delivery and mobility. This blogging has mainly been a   personal enrichment , as it forced me to dive deep into a number of different topics, not only in researching for content, but also in trying to identify trends, innovations and patterns into these topics. Furthermore it allowed me to have several very interesting conversations and discussions with passionate colleagues in the financial industry and to get more insights into the wonderful world of blogging and more general of digital marketing, exploring subjects and tools like: Search Engine Optimization (SEO) LinkedIn post optimization Google Search Console Google AdWorks Google Blogger Thinker360 Finextra …​ Clearly it is   not easy to get the necessary ...

The UPI Phenomenon: From Zero to 10 Billion

If there is one Indian innovation that has grabbed   global headlines , it is undoubtedly the instant payment system   UPI (Unified Payments Interface) . In August 2023, monthly UPI transactions exceeded an astounding 10 billion, marking a remarkable milestone for India’s payments ecosystem. No wonder that UPI has not only revolutionized transactions in India but has also gained international recognition for its remarkable growth. Launched in 2016 by the   National Payments Corporation of India (NPCI)   in collaboration with 21 member banks, UPI quickly became popular among consumers and businesses. In just a few years, it achieved   remarkable milestones : By August 2023, UPI recorded an unprecedented   10.58 billion transactions , with an impressive 50% year-on-year growth. This volume represented approximately   190 billion euros . In July 2023, the UPI network connected   473 different banks . UPI is projected to achieve a staggering   1 ...

AI in Financial Services - A buzzword that is here to stay!

In a few of my most recent blogs I tried to   demystify some of the buzzwords   (like blockchain, Low- and No-Code platforms, RPA…​), which are commonly used in the financial services industry. These buzzwords often entail interesting innovations, but contrary to their promise, they are not silver bullets solving any problem. Another such buzzword is   AI   (or also referred to as Machine Learning, Deep Learning, Enforced Learning…​ - the difference between those terms put aside). Again this term is also seriously hyped, creating unrealistic expectations, but contrary to many other buzzwords, this is something I truly believe will have a much larger impact on the financial services industry than many other buzzwords. This opinion is backed by a study of McKinsey and PWC indicating that 72% of company leaders consider that AI will be the most competitive advantage of the future and that this technology will be the most disruptive force in the decades to come. Deep Lea...
