Introduction:
Non-fungible tokens (NFTs) have been growing in popularity, slowly but surely. NFTs allow for digital scarcity and provable ownership of unique, one-of-a-kind assets. In this research piece, we will introduce you to non-fungible tokens and the different platforms where you can use and trade them.
What is Fungibility?
Before we delve into the intricacies of NFTs, it’s worth looking at the difference between “fungible”and “non-fungible.” A fungible item or token is, for all intents and purposes, interchangeable with another unit of the same thing.
For example, one Bitcoin is equal to another Bitcoin, just like one US dollar is equivalent to another US dollar. If you lend your friend a $10 note, you wouldn’t need them to repay the loan with the same $10 note – any $10 note will do. Things that are non-fungible, on the other hand, are not interchangeable with one another, and have unique properties that can make them radically different from one another, even though they may look similar. There are many examples of non-fungible items in the real world, such as paintings, concert tickets, and so on. Although two paintings may look similar, they may have drastically different level of rarity.Similarly, front row tickets at a concert are much more valuable than tickets for the back row.
What are Non-Fungible Tokens?
This brings us to non-fungible tokens (NFTs). What are they, and how are they different from non-fungible digital assets like domain names or Twitter handles? Non-fungible tokens are an extremely powerful kind of token that allows for a flexible way to represent non-fungible assets on a blockchain. Their main properties are:
Unique: Non-fungible tokens contain within their code information that describes the properties of each token that make them different to others. A piece of digital art might have coded information about individual pixels, while tokenized in-game items might contain details that allow the game client to understand which item the player owns and its attributes.
Traceable: Each NFT has a record of transactions on-chain, from when it was created, including every time it changed hands. This means each token can be verifiably authentic, and not a counterfeit – obviously a very important thing for owners and prospective buyers!
Rare: In order for non-fungible tokens to be attractive for buyers, they should be provably scarce. This will ensure that assets remain desirable in the long run, and that supply does not outstrip demand.
Indivisible: NFTs mostly cannot be transacted as fractions of a whole.Just like how one cannot purchase half of a concert ticket or trading card, non-fungible tokens cannot be split into smaller denominations.
Programmability: Like all traditional digital assets and tokens built on smart contract blockchains, NFTs are fully programmable.CryptoKitties and Axie Infinity have breeding mechanics coded directly into their tokens.Even more functionality is possible.
In other words, NFTs combine the best traits of decentralized blockchain technology with non-fungible assets. Unlike regular digital assets that are issued and regulated by centralized entities, which can be taken from you at any time, it is possible to truly own and control your own NFTs.
Use Cases:
As you can imagine, NFTs can be extremely powerful since they can represent literally any asset, digital or real. Below are just some uses for NFTs:
Gaming: Trade-able in-game items are also one potential use case for NFTs. So far, we have seen most implementations revolve around turn-based battle or trading card games like Axie Infinity or Gods Unchained. With NFTs, however, games such as Fortnite or CS:GO with vibrant item economies may one day support on-chain item trading.
Art: With the launch of the art marketplace Rarible and their yield farming incentive program, tradeable digital art has become a hot topic. NFTs allow artists to monetize their artwork and protect their copyright. NFTs also allow artists to receive royalties every time their creations change hands.
VirtualAssets: The Ethereum Name Service and Unstoppable Domains have turned .eth and .crypto domain names into NFTs, which can then be traded. Real estate in virtual worlds Decentraland and Cryptovoxels have also been tokenized into NFTs.
Real-WorldAssets: One of the original imagined purposes for NFTs was to tokenize real-world assets that can then be traded. OpenLaw created a system to trade real estate using the ERC-721 token standard, and Nike last year also patented a system to tokenize shoes.
Identity: With NFTs, users would be better able to protect and control their personal information, like medical histories, birth certificates, and more.
History of Non-Fungible Tokens
Non-fungible tokens have been around for longer than you might think. After Bitcoin’s founding in 2009 and the initial explosion in token types such as Litecoin, Ripple, and so on, many people were looking to innovate on blockchain technology to create newer, more powerful tokens. In this section, we will walk you through a brief history of NFTs.
Colored Coins:
The earliest predecessors of non-fungible tokens were arguably colored coins, which were first formulated in a blog post by Yoni Assia in March 2012. These were very small units of Bitcoin which were “colored” with specific attributes coded into metadata using Bitcoin’s scripting language. In this way, units as small as one satoshi (0.00000001 BTC) could represent any asset you can imagine, be it a dollar, shares in a company, a house, or digital collectibles.
Although the concept of colored coins was very promising and potentially powerful, they had major flaws and roadblocks:
The Bitcoin network didn’t officially support colored coins. Hence, it was up to wallet providers to recognize the existence of colored coins.
The minimum transaction size for a Bitcoin transaction back then was patched to be 5,430 satoshis (0.000543 BTC), which was much too large for the implementation of colored coins.
Colored coins allowed for not just the creation of NFTs, but any asset. Hence, the creation of Ethereum’s ERC-20 token standard in 2015 took away much of the purpose of colored coins, since ERC-20 are much more flexible Meanwhile, platforms such as Counterparty took over colored coins’ NFT function.
As such, colored coins slowly fizzled and died out. Coinprism, the first wallet to support colored coins, shut down in 2018, citing regulatory pressure and the inflexibility and relative sluggishness of the Bitcoin network.
Counterparty was founded in 2014, building on the idea of colored coins to issue non-fungible and semi-fungible tokens. Counterparty’s founders understood that Bitcoin did not support the features that would allow for the creation of a robust asset creation and trading platform.
In 2015, the mobile game Spells of Genesis became the first to issue in-game assets onto any blockchain, doing so through Counterparty. The platform saw further success in 2016 as the popular trading card game Force of Will issued cards on Counterparty. At the time, Force of Will was the fourth most popular trading card game in North America, behind household names such as Magic: The Gathering, Pokémon, and Yu-Gi-Oh.
Although blockchain-based in-game assets would continue to see use, the biggest innovation came in 2016 when people began issuing limited edition Rare Pepes on Counterparty, based on the popular and at times controversial meme character Pepe the Frog. Of course, the idea of a “rare” online picture is absurd since they can easily be copied, but people had been discussing the notion since 2015.
Rare Pepes Represent Meme Power and Digital Scarcity:
Although you may be tempted to dismiss Rare Pepe cards as silly, in actuality they serve as a powerful demonstration of the human desire to own something that is rare and has some commonly perceived aesthetic or collectible value, a combination which allowed Rare Pepes to become an instant sensation. Rare Pepes can sell for thousands of dollars, with the pinnacle being a landmark digital art auction in 2019, where an ultra-rare, one- of-a-kind Homer Simpson Pepe (pictured above)sold for $38,500.
CryptoPunks:
With Rare Pepes providing a recipe for success, John Watkinson and Matt Hall in June 2017 created CryptoPunks – algorithmically-generated, 24x24 pixel characters that live on the Ethereum blockchain. Only 10,000 characters with unique appearances were created. The CryptoPunks founders allowed anyone to claim the Punks for free – needless to say, all 10,000 were quickly claimed.
Every CryptoPunks is Unique in Appearance:
Different Punk types and attributes have different rarities, and certain combinations of rare or desirable traits can be tremendously valuable. For example, ape-types are the second rarest. The mostexpensive Punk ever, an Ape Punk witha Hoodie,sold for 150 ETH (US$71,403) just this month!
Types and Attributes Combine to Create Unique Punks:
Although CryptoPunks were already viral sensation when they first launched, lately they have really been catching the attention of the NFT community. As the earliest “true NFT” launched on Ethereum, many are beginning to treat Punk ownership as a badge of honor, almost as a status symbol demonstrating that the owner is a “true OG” of the crypto world. Over the past three months, CryptoPunks realized prices have skyrocketed to thousands of dollars.
Since CryptoPunks wascreated before the invention of the ERC-721 non-fungible token standard,the founders had to use a modifiedversion of the ERC-20 token for the Punks (token address). Nevertheless, CryptoPunks served as the inspiration the ERC-721 standard, paving the way for the truly viral NFT sensation to come: CryptoKitties.
CryptoKitties:
CryptoKitties was founded in October 2017. It was a virtual game that allowed players to breed, raise, and trade virtual cats with unique genomes that influence their appearances. Released in the midst of the crypto boom of late 2017, CryptoKitties soon began to rise exponentially in value, with one CryptoKitty even fetching 600 ETH (US$172k at the time). The project made appearances on mainstream media everywhere, including the likes of CNN, CNBC, and the Financial Times.
CryptoKitties: The First Non-Fungible Token Hit:
Today, the activity in CryptoKitties has abated somewhat, falling in volume of tokens traded over the past week to 13th place according to NonFungible.com, but we cannot overstate the impact that CryptoKitties has had on the NFT landscape – the project is still ranked #1 in all-time volume traded, with over $38 million worth of CryptoKitties having been transacted since 2017.

Summary:
In conclusion, although we have seen promising signs of life within the NFT space, there is still a long way to go before this novel application of blockchain technology reaches mass adoption. The technology has definitely come a long way since its inception in 2012, but it will undoubtedly take some more time before it is proven that NFTs are more than just an ultra-niche sector for early adopters to play in.
Key Takeaways:
Non-fungible tokens combine the best traits of decentralized blockchain technology with non-fungible assets to create provably unique, provably scarce, and provably authentic tokens utilizing blockchain technology.
NFTs are applicable in a wide range of use cases, including: collectibles, gaming, art, virtual assets, tokenizing real world assets. They also allow for a flexible way to store, control, and protect the information related to one’s identity.
Non-fungible tokens have had a long history, since 2012 with the introduction of colored coins built on the Bitcoin network. Since then, NFTs have primarily moved to Ethereum, where non-fungible token standards such as ERC-721 and ERC-1155 can be minted and traded easily and seamlessly.
The first NFT collectibles that really took off in popularity were Rare Pepes. This was followed by CryptoPunks, and then arguably the most successful and well-known NFT project ever, CryptoKitties.
During the Ethereum boom of late 2017 and early 2018, NFT activity in CryptoKitties drove a huge spike in activity. When the market crashed in 2018, however, interest in NFTs was also impacted and stagnated until late 2020, when NFTs saw a resurgence.
Despite this, the adoption of NFTs is still low relative to the tens of millions of people who own cryptocurrencies worldwide. The roadblocks preventing mass adoption of NFTs are: inaccessibility, the newness of the technology, the volatility of transaction fees, difficulty to link real-world assets to NFTs, and regulation.
