Non-fungible what now? If you poke your nose around the blockchain space these days you have almost certainly heard a lot of hype around these things called NFTs, or non-fungible tokens. How can these digital things be selling for millions of dollars? Hopefully, this post can help shed a little bit of light on this rapidly growing section of the crypto sphere.

What is a non-fungible token?

According to the Ethereum website:

“NFTs are tokens that we can use to represent ownership of unique items. They let us tokenize things like art, collectibles, even real estate. They can only have one official owner at a time and they’re secured by the Ethereum blockchain – no one can modify the record of ownership or copy/paste a new NFT into existence.”

Let’s break this definition down a little bit, but first, we will take a quick look at what the terms fungible and non-fungible mean.

Fungible and Non-Fungible assets.

Non-fungible is a term used in economics to describe an item that is defined by its unique properties. This definition of the item means that is not interchangeable. A car would be an example of a non-fungible asset. The unique properties of one specific car make it inherently different than any other physical car. Most of the things in your house would also be examples of non-fungible assets. Think of things like your computer, watch, pants, or mattress. These are all things that are defined by their unique characteristics.

The concept of a non-fungible asset becomes much more clear when you compare it to a fungible asset. Fungible assets, by contrast, are defined by their value. The $20 bill in my wallet is fungible. Whether I have this exact $20 bill or another physical bill makes no practical difference since the bill is defined by its value rather than its unique properties (which in the case of a $20 bill could be how crinkled it is). Other examples of fungible goods include commodities like grain or common shares in a company.

Fungible and Non-Fungible assets


A non-fungible token, then, is a cryptographically secure way of representing a unique asset. Once the asset, whatever it may be, is tokenized it cannot itself be modified. Additionally, there exists a cryptographically verifiable means of determining the owner of the asset.

But what do these tokens represent?

Well, really it could be anything. Given the digital nature of blockchains, assets that exist in a purely digital form are the easiest to tokenize on-chain. Think of files such as a .jpg file containing a piece of art, an .mp3 file containing a song, or even a .pdf file containing a written document. The creator of a digital file can tokenize it on a blockchain, creating in the process a non-fungible token. This tokenized entity can then be bought and sold in the same way that any tangible non-fungible asset, such as a painting, is in the physical world. Recent headlines are showing the use cases of NFTs in the digital content industry.

NFTs in the Digital Content Industry 

The biggest use of NFTs today is in the digital content realm. That’s because that industry today is broken, with the profits and earning potential of content creators swallowed by platforms they use to share their work. Take, for example, a photographer who shares their work on Instagram. The artist’s content makes money for Instagram who uses the platform to sell ads to the artist’s followers. While the artist may receive exposure for their work, more often than not through these platforms they are simply excluded from any monetary benefit.

In the world of NFTs however, the creator of the content does not have to hand ownership of their work over to a centralized platform for publication. Instead, ownership of the content is baked into the content itself. This gives the creator much more autonomy over their own work.


NFTs in other industries

NFTs are a new phenomenon and still currently exist on the fringes, making headlines, in part, due to the inability of the masses to fully wrap their heads around the idea that an intangible image file could sell for $69 million. While the large dollar figures for NFT sales reaching headlines may be attributable, in part, to a rapidly expanding bubble of hype, there is at least some real value to the technology.

Non-fungible tokens could have some very interesting applications in more mainstream commerce. This could be applied in any instance where ownership and possession of an asset are not inextricably intertwined. Think about the deed to a house or the ownership documents for a car. These documents were designed as a means of verifying ownership in a pre-blockchain world. While they serve their purpose, they are often considered to be inefficient and create a reliance on a centralized entity to verify their authenticity. A properly designed NFT could be used to represent a physical car and subsequently its legal owner in the same way that an ownership document at the ministry of transportation does today.

NFTs and trade finance

In trade finance, there are also many examples of real-life assets and processes that could be represented or streamlined with non-fungible tokens. Think of a traditional shipment in global trade where the consignee must present a bill of lading to the shipper in order to take legal possession of the goods. The bill of lading in this instance, through the verifiable processes that have been put in place in the industry, serves to indicate that the consignee does in fact own the goods and that the shipper can transfer them physical possession. Tokenization of this bill of lading, or even the shipment itself, would allow this same ownership to be verified in a decentralized manner.

Of course, this is a very simplified and high-level glance at one possible application of these tokens in international trade, and it leaves many details and nuances up to the imagination. However, it does provide a taste of what might be to come in the industry down the road. There are many companies in the TradeTech space currently exploring the use of tokenization and digital documents for trade transactions.
