What is an NFT? How Does It Work And What Are Five Practical Use Cases For NFTs?

NFTs are an emerging type of blockchain-based digital asset which has been increasingly in demand over the past few months. They are non-fungible and irreplaceable, like rare snowflakes. While cryptocurrencies are strictly synonymous with buying goods only, NFTs can be purchased, sold, traded, and even self-created. In addition, they add a unique level of value to the blockchain space in general. Any digital work, including physical goods, which can be represented in digital forms, such as a photo, video, or scan, can be turned into a non-fungible token.

What is an NFT?

NFTs are used to secure licenses for digital goods that users can exchange. NFTs are a new type of cryptocurrency asset. As one person can only own each NFT, they are ideal for representing ownership rights to digital items like collectibles and games. There are various types of NFTs, but the most common is a metadata file containing information encoded with a digital version of the work that is being tokenized. The other type is where the entire work is uploaded to the blockchain; these are less common as it is expensive to upload information to the blockchain. NFT

How do NFTs work?

NFT’s non-fungible nature makes it different from cryptocurrencies. Many NFTs can represent the same value but have an additional value based on their uniqueness. Due to this asset’s nature, multiple people can own, trade, and use the same item, like a rare coin or other collectible items. In addition, these new types of assets enable game items to be stored outside the game and sold on third-party platforms.

Some examples of NFTs

  • Unique digital art
  • Crypto pets
  • In-game assets
  • Digital fashion wearables
  • Domain names
  • Tickets or coupons
  • Music albums
  • Posters

How can NFT be used?

NFTs are used to transfer ownership of digital assets between users, represent rights and permissions within decentralised applications, track the provenance of digital assets, create digital collectibles, build online NFT marketplaces, and much more.

NFTs have many potential uses, but there are 5 practical examples:


A metaverse is a concept that represents a 3D universe of shared virtual worlds and digital assets, where you can own your own digital property, such as land, objects, characters, your avatar, and buildings in an interactive and immersive way where the digital assets are recorded on the blockchain.


NFTs are used in gaming to create unique collectible items that represent in-game content. For example, the CryptoKitties game uses NFTs to make digital representations of real-life cats and their owners. However, the most popular use for NFTs in gaming is for trading or selling items like skins, armors, and swords.NFTs are unique, rare, and indivisible and the blockchain networks that underpin NFTs facilitate payer ownership, provable scarcity, immutability, and interoperability. 

Real Estate:

People can use non-fungible tokens to buy real estate. NFTs can simplify real estate transactions, enable smart contracts for property, and even create a home rental service. They can also protect sensitive data like credit card details while doing so.

Medical Records:

Hospitals can use the NFT ledger to store, manage, and retrieve medical records without compromising confidentiality. In addition, NFTs get reapproved with every use due to their immutable nature. In addition, their security and traceability get enhanced by keeping them on an immutable ledger.


With NFTs, individuals who don’t have physical identification can obtain a digital identity that can prove who they are and where they live. NFTs will also help eliminate cheating and voter fraud since they will serve as official voting records.

The benefits of NFTs are many:

Non-FungibleTokens can be tracked and verified by the network. This makes them secure and difficult to forge. They can solve problems of security using smart contracts to store and manage ownership information underpinned by blockchain technology.


The ownership of an NFT is transparent. Anyone on the blockchain can view and verify it. Because of this, they are ideal for representing digital assets such as collectibles, games, or real estate.


The ease of transferring NFTs between users makes them ideal for digital applications.


NFTs are decentralised and not governed by any central authority, so they are unassailable.

How can you invest in NFTs?

NFTs are proliferating, and there are now hundreds of different types available. However, when it comes to investing in Non-FungibleTokens, there are a few things that you need to take into account.
  • First, various types of Non-FungibleTokens and tokens representing real-world assets are available, so deciding what you will invest in is essential.
  • Second, how to store them? Every kind of NFT has its storage requirements, so make sure you research this before investing.
  • Finally, it would be better to consider how you will trade your NFTs. Several different platforms are available, so you need to find one that suits your needs. 
With these things in mind, investing in Non-FungibleTokens can significantly diversify your portfolio and increase your chances of generating returns if you’re considering investing.


Non-FungibleTokens are genuinely revolutionising how we view art and collectibles by literally assigning each piece of NFT art a digital property address on the blockchain. The next generation of history books could have a fighting chance by looking at Non-FungibleTokens as the seeds for a decentralised future instead of just glorified digital picture frames.
