Non-fungible tokens, or NFTs, are distinct pieces of digital media that are verifiably scarce and unique. Powered by blockchain technology, NFTs are already reshaping the landscape of digital art.
Breaking down “Fungibility”
Broadly speaking, there are two categories of assets: fungible and non-fungible. Fungible describes any asset that retains equal extrinsic value to an asset of like kind. The most common example of a fungible asset is currencies, like the ones we use every day. If two people are holding a dollar, they typically won’t care if they exchange the dollar with each other. Neither dollar is worth more than the other; they can be exchanged without either party sacrificing any value.
A non-fungible asset is a unique asset that cannot be exchanged equally for an asset of like kind. A common example of a non-fungible asset is a collectible or memorabilia. A baseball signed by Babe Ruth cannot be equally exchanged for a regular baseball, even though they are similar objects. An original Monet cannot be equally exchanged for a replica Monet, even though they may appear identical.
A non-fungible asset is a unique asset that cannot be exchanged equally for an asset of like kind.
The distinction between fungibile and non-fungible is a common concept. Looking at the setting around you, consider if you’d happily trade an object in sight for a visually identical version. You will likely find yourself surrounded by more non-fungible items than you may have realized, though we certainly do not refer to our collectibles or valuables as “non-fungible assets” in everyday speech.
The line between fungibles and non-fungibles can blur. A fungible asset suddenly endowed with intrinsic value or unique abilities can evolve into a unique, non-fungible asset. Conversely, a non-fungible asset suddenly rendered common (e.g. your signed Babe Ruth baseball discovered to be a counterfeit) may find itself closer to a fungible asset in its particular value.
Non-fungible assets and the digital world
For an asset to be non-fungible, it requires some form of scarcity or uniqueness. This has never before been possible online in a sustainable, scalable way 一 until NFTs.
Scarcity is notoriously difficult online. Content flows too freely; it is too easily copied, replicated, shared, and distributed. This is something we can recognize firsthand. It is remarkably simple to distribute content 一 including artwork 一 online, creating an abundance of media that exposes us to digital art but hinders us from attaching value to it.
They allow for online assets to have verifiable scarcity and ownership that cannot be manipulated.
Original ownership, scarcity, and uniqueness are hard to determine online, muddying the waters of how precisely to value works created in the digital realm. This has made it difficult for digital artists to establish and maintain monetized creative businesses. It has created opportunities for creative theft and plagiarism. Perhaps most detrimental, it has made it harder for people and would-be collectors to value digital art in a similar way we value physical art.
NFTs are a paradigm shift for digital art and other forms of online media. They allow for online assets to have verifiable scarcity and ownership that cannot be manipulated. They bring the elements that endow physical art and assets with value into the digital realm. Along the way, they open up the doors for valuable digital art and create opportunities for artists that never before existed.
How do NFTs establish digital scarcity and ownership? The reason we refer to these assets as non-fungible tokens rather than non-fungible assets (or even digital non-fungible assets) is because they are uniquely made possible by blockchain technology.
Blockchain technology and NFTs
In its simplest explanation, blockchain is a digital, decentralized, permissionless ledger. Decentralized meaning it is not owned by anyone. Rather, it is collectively stored and maintained by a group of people who do not know each other. This is in opposition to centralized ledgers (servers), which are controlled and maintained often by single entities. Permissionless meaning anyone can record information, maintain the ledger, or browse the record activity.
Blockchain networks, like the physical world, have both fungible and non-fungible assets. Fungible assets are the ones that are commonly known, including BTC (bitcoin) and ETH (ethereum), among others. These assets, like the dollar discussed earlier, are always equal to each other in value. The exchange of ETH between addresses isn’t the exchange of a unique asset, rather an exchange of value, like a dollar being traded in between hands. Fungible tokens like ETH are also divisible, meaning (nearly) any fractional amount of ETH can be bought and sold.
Once minted by artists and sold by collectors, NFTs can continue being traded among collectors and art communities, operating like any secondary market. The provenance of each NFT is always available, so collectors can ensure authenticity prior to buying or bidding.
Blockchain networks like Ethereum, too, support non-fungible assets, which have become increasingly popular in the last few years, and within the last year especially so. Dissimilar to a fungible asset like ETH, a non-fungible token (NFT) is a distinct, indivisible token on a blockchain network. Transferring ownership of an NFT transfers the entire token from one address (i.e. user) on the network to another. NFTs cannot be divided into smaller denominations (you wouldn’t expect to cut your Babe Ruth baseball in half and expect it to retain its value).
Critically, NFTs are also verifiably unique. When a user on a blockchain network mints (creates) an NFT, they mint a specified number of tokens. This is why NFTs are often described as “1x1” or “1x100”, listing their scarcity in relation to the number of identical NFTs released in that minting instance. Once released, that number cannot be changed and that set of assets is immutably verified to have originated from that creator at a certain point in time. Even if the artist mints more of the same NFT artwork in the future, it will be publicly and irreversibly verifiable which NFTs were part of the original set and which were part of later sets (analogous to editions of a print). When these NFTs are launched on a public network like Ethereum, the information is there for everyone to see themselves, reducing the cost and complexity of verifying the authenticity, originality, uniqueness, and ownership of particular assets.
Once minted by artists and sold by collectors, NFTs can continue being traded among collectors and art communities, operating like any secondary market. The provenance of each NFT is always available, so collectors can ensure authenticity prior to buying or bidding. Moreover, NFTs enable automatic commissions, just one component of the unique ability for NFTs to empower artists through digital mediums. As distinct pieces of code on a blockchain network, NFTs can be hardcoded to return a certain percentage of any sale to a designated address, including the minter’s original. This means the artist will continue to benefit from the future sales of their artwork, even if they have no direct influence over the sale itself.
The influx of attention and investment in the NFT space in the last year has proven there is vast interest not just in digital art, but specifically in the unique value proposition of digital scarcity and verifiable ownership. The participation from both creators, collectors, and curators alike demonstrates the interest and benefit to all sides of the artist market.
As blockchain technology continues to evolve, the NFT ecosystem will evolve alongside, growing not just in size but in complexity and opportunity as well. Sotheby’s foray into NFTs is beginning with ‘The Fungible’, a collection of digital art by renowned creator Pak. By leveraging blockchain technology and non-fungible tokens (NFTs), The Fungible not only provides collectors with novel assurances of scarcity and ownership, but exposes them to the unique features with which technology can endow artwork. Through this collection, Pak scrutinizes our understanding of value. What does value mean, and from where does it derive authority?
