Non-Fungible Tokens — Everything You Need to Know About NFTs

NFT Cards Learn

Are you looking for a guide on everything you need to know about non-fungible tokens (NFTs)? Then you are in the right place. In this CoinQuora article, we will learn what are NFTs, how do NFTs work, various NFT use cases, and the best NFTs today.

The NFT ecosystem has experienced a historic boom during 2020, with its market capitalization hitting beyond $300 million. Hence, it is now a value-generation industry.

In retrospect, the NFT industry made headlines before the end of the 2020 crypto bull run. Since then, decentralized finance (DeFi) and NFTs’ early initiatives become more visible to crypto users and traders. As a result, NFTs are expected to play a huge role in the expanding cryptocurrency market.

What is a non-fungible token?

A non-fungible token (NFT) is a unique digital token created using blockchain technology. NFTs represent a wide range of tangible and intangible items. What makes NFTs beneficial is it ensures digital ownership, as well as hold real-world value.

In reality, we already have a lot of non-fungible digital assets. These include airline mileage points, in-game items, event tickets, Facebook and Twitter social handles, and many more. We own these by context, but we don’t own them fully.

When it comes to digital ownership, NFTs are the most favorable solution. Due to blockchain, a coordination layer for digital assets is provided. Thus, giving users full ownership and management of their assets.

NFTs have individual characteristics, making them unique, rare, and indivisible.

Moreover, NFTs are built on smart contracts. These contracts contain specific information that makes each non-fungible token different from one another. In this way, no NFT is similar to any other NFT. Hence, these cannot be interchanged and broken down into smaller units.

Generally, NFTs represent the expanding digital resource economy. It is where users can prove ownership of goods — physical or virtual — via unique digital tokens recorded on the blockchain. Many types of NFTs are existing today such as art, collectibles, gaming, metaverses, sport, and utilities. More explanation on each NFT use case below.

How do non-fungible tokens work?

Non-fungible tokens can represent a unique object, a virtual land, a piece of art, or a digital artifact. In fact, what each NFT represents is all cryptographically-programmed to be unique, whereas cryptocurrencies are created equally. Hence, non-fungible tokens are each unique and limited in quantity.


Generally, those who want to create NFTs can use the Ethereum blockchain. Common non-fungible token standards are ERC721 and ERC1155. In comparison, the blueprint for fungible tokens is ERC20. With thousands of ERC20 tokens in the market, these digital assets are commonly used by crypto projects for governance, fundraising, payments, and others.

By and large, developers can build common, reusable, inheritable standards relevant to all non-fungible tokens. These include ownership, transfer, and simple access control.

ERC721 is the first standard for representing non-fungible digital assets. In detail, ERC721 is an inheritable Solidity smart contract standard that provides a mapping of unique identifiers to addresses. Moreover, it also follows a permissioned way to transfer these assets.

ERC1155 brings the idea of semi-fungibility to the NFT world. With this token standard, IDs represent not single assets but classes of assets. Thus, by using a single smart contract to represent multiple tokens at once, this approach can be more practical and cost-effective. There’s no need to deploy a new contract for each token type. Instead, a single ERC1155 token contract can hold the entire system state to avoid complexity.


The issuance of NFTs allows for a higher degree of interoperability. This will certainly benefit the crypto users holding them. It basically means that unique digital assets can be transferred between different applications seamlessly.

To explain further, non-fungible token standards allow NFTs to move easily across multiple ecosystems. Therefore, when a developer launches a new NFT token project, these NFTs are immediately viewable on supported wallet providers, tradeable on open marketplaces, and, visible inside virtual worlds.

At present, there are still many works to be done in achieving true NFT cross-platform interoperability. By definition, interoperability means the assets can come from any game or from multiple chains. Soon, different blockchain-based virtual worlds can enable specific assets to function within their environments.


Non-fungible tokens can be bought, sold, and traded on top NFT marketplaces like OpenSea, Rarible, SuperRare, and Axie Marketplace. These markets connect buyers with sellers, making the value of each token unique. Similarly, NFTs are prone to price changes in response to the market’s supply and demand.

Without a doubt, the ability to be traded freely on open marketplaces is one of the most attractive features of NFTs. You and I can now move items (either physical or digital in nature) into marketplaces where we can take advantage of trading opportunities.

Particularly for game developers, the tradability of assets represents a transition from a closed economy to an open, free-market economy. As a result, game developers no longer have to manage every piece of their economy. Instead, they can let free markets have a say.


The tokenization of real-world assets could introduce some well-needed liquidity to these markets. In this way, previously untapped revenue streams are opened. Fine art, real estate, and rare collectibles are just some of the most liquid and profitable NFTs.

Moreover, the instant tradability of non-fungible tokens will lead to higher liquidity. Taking this into account, NFT marketplaces can cater to a variety of audiences — from hardcore traders to more novice players. As a result, a wider pool of buyers has greater exposure to the assets.

Similar to how the ICO boom of 2017 gave birth to a new asset class, NFTs expand the market for unique digital assets. NFTs truly offer investors additional liquidity over their assets when they need it.

Immutability and Provable Scarcity

NFTs are provably scarce assets. What does this mean? To put it simply, each non-fungible token contains a code that indicates its specific digital identity. Hence, creating unique digital goods can be used to represent rare physical assets with a trackable history of ownership.

Scarcity is an important aspect that makes NFTs special. While developers have the freedom to generate an infinite supply of certain assets, they also have the power to limit their number in existence. Broadly speaking, the possibilities for exclusive and rare items that can be traded are endless.

As all NFTs are created on the blockchain, it is immutable in nature. Smart contracts allow developers to enforce persistent properties that cannot be modified after issuing NFTs. In this way, properties do not change over time by encoding them on-chain.

Non-fungible token use cases

While the market size of NFTs is still quite small compared to the trillion-dollar worth of Bitcoin, NFTs are expected to bring about new changes to not only the collectibles industry but also the blockchain world in the years to come.

As a matter of fact, people give emotional and aesthetic value to items. Thus, they are willing to pay a lot of money for them. Yet, on the Internet, almost anything can be easily copied, shared, and stolen. Blockchain technology works to resolve that.

NFTs rely on the blockchain to designate an official copy of a piece of digital media. This allows artists, musicians, influencers, and sports franchises to sell authentic tokenized assets. When you buy an NFT, the transaction becomes a permanent public record, serving as a sort of certification of authenticity. This cannot be altered or erased at any point.


Protecting copyrights can be a nightmare for digital artists. Through NFTs, someone can create digital art and proudly showcase it in a virtual space for buyers. No intermediaries and unnecessary costs and processes involved. Moreover, with blockchain, both the artist and buyer have true proof of ownership.

Although non-fungible tokens (NFTs) are a way to prove ownership of digital art, the cool image or video the NFT owner has doesn’t actually live on the blockchain. Instead, the NFT refers to a file that sits somewhere else on the web. Thus, if the file is stored at a traditional web address and taken offline, the NFT owner may experience some trouble.


As we’ve seen with the CryptoKitties craze, NFTs are being used to create entirely new types of collectibles. To point out, it’s even possible to buy tokenized versions of your favorite celebrities or sports stars. Not to mention digitizing traditional collectors’ items such as baseball cards, coins, and stamps.

Various NFT marketplaces now allow fans to own, share or trade digital items in a manner similar to physical trading cards or collectibles. Moreover, brands can easily license and monetize limited edition, rare, and exclusive digital assets based on their intellectual property (IP).


Current gaming platforms are in for a treat with NFTs. The modern shift in power to the gamer means game developers need to up their game. Accordingly, the broader success of gaming DApps will likely play a role in further catalyzing NFT adoption.

NFTs will certainly change the way we play. Gamers will trade more NFTs, and blockchain gaming will pave its way further into the gaming world. To illustrate, Pteria DAO is an innovative project that focuses on the relationship between gaming and the NFT world.


In a nutshell, a metaverse is a digital world where anything we can imagine can exist. These can interconnect different technologies like virtual reality (VR), augmented reality (AR), blockchain, and cryptocurrencies.

In order for digital items to have real and lasting value, they must exist independent of an entity. This is possible with NFTs. In line with this, the decentralized nature of NFTs will make the metaverse an open ecosystem.


Sports leagues such as NBA have millions of fans and followers. This can be seen not only in the real world but as well in the digital space. Thus, to create further engagement with fans, mintings NFTs are now being explored.

Dapper Labs has created NBA Top Shot which allows basketball fanatics to own collectible and game highlights through NFTs. As more and more NBA players and fans want to get their hands on their moments, the more legitimate Top Shot will be in the future.
