For instance, Chris Torres who created the Nyan Cat, a popular meme on the internet platform sold out one of his creations, a viral GIF for three hundred Ethereum.

Similarly, there is musician Grimes who sold her crypto art using non-fungible tokens worth $5.8 million. The Crypto industry is booming and the NFT space is getting flooded with celebrities and general crypto enthusiasts as well. So, here in this article, we will elaborate on non-fungible tokens which are taking the crypto industry by storm. 

What are Non-Fungible Tokens (NFT)?

NFT or Nun-fungible tokens are known for their uniqueness. They are cryptographic tokens that are one-of-its-kind and known for their unique set of characteristics. They are also referred to as collectibles and antiques. The value of the NFTs is usually due to the uniqueness they hold. These digital assets are not interchangeable as they are different from each other. Each NFT defines different characteristics and has a unique value. 

The history of NFT – how and why did it start?

Non-fungible tokens can into existence in 2017. It started with a game – ‘Cryptokitties’ where the players have to buy limited edition ‘virtual cats’ and also ‘breed’ the same which means generating them. These are used to provide the players with prizes for the games they win. The game developers started using the NFTs for these prizes, collectibles, and other in-game rewards. These tokens can be transferred to other players as well using NFT specialized blockchain marketplace. However, these tokens have become popular because of the digital artists and the other celebrities who sell their collectibles and artwork for NFTs. 

Characteristics of NFT

The primary characteristic which set NFTs apart are – 

  • Non-interchangeable: The non-fungible tokens are neither interchangeable nor interoperable. These tokens are built on the standards of ERC – 721 and thus the information which is in these tokens cannot be interchanged with any other tokens or used otherwise.
  • You cannot destroy NFTs: These token are indestructible. These tokens are managed by blockchain and also the information is stored in them. So, the security level is too high for anyone to destroy these tokens.
  • Unique and rare: NFTs always stay away from the crowd and resonates with artwork that is real. They make use of blockchain to keep themselves authentic. It helps in distinguishing between original items from the replicas. This uniqueness of these tokens sets them apart. Moreover, the total number of NFTs is really low and they are considered to be scarce digital assets. However, their value is higher than many other digital assets because of their uniqueness and thus they are quite popular.
  • NFTs are indivisible: You cannot divide and send a portion of the NFTs like other cryptocurrencies. This is because the NFTs do not have any defined value like other cryptocurrencies and thus cannot be divided.

How do Non-Fungible Tokens work?

Non-fungible tokens work differently from other digital assets. They being unique with their own sets of characteristics cannot be manipulated in any way. You can prove that the tokens are yours as they have ownership. You can hold it for eternity as well as sell the same. In some of the NFTs, the resale royalties are acquired by the original creator of the tokens. Whenever NFT holders sell their tokens, they earn royalties.

The NFTs can be kept in Ethereum based wallets and they remain there safely. There is no need for any intermediary for selling these tokens. You can sell the tokens in the open market as well as in a peer-to-peer setup. For the NFTs, you can determine the scarcity as well. 

Two aspects that need to be understood in respect to Non-fungible tokens are Scarcity and Royalties. 


When you sell the NFTs, royalties are being paid to the creators as well as the sellers (holders). It is one of the most powerful concepts which are still in its nascent stage of development. Even there are some of the platforms which have royalties for their artists as well. It works automatically, so whenever there is a sale of the NFT, the royalty for the same gets credited into the account of its creator automatically. However, the royalty programming should be done right to get the royalties in your account automatically otherwise it is difficult as everything else is still manually processed and very slow. 


The creator of the Non-fungible tokens can decide the scarcity of the digital assets they create. Since every NFT is unique thus the creator can create and fix the number of NFTs. Each of the NFTs will be different from each other slightly and that is where the uniqueness lies. Now the creator can decide whether all the NFTs will be similar with slight differences or there will be a few with major differences which can be collected as collectibles as well. 

Why do NFTs Have Value?

The value of non-fungible tokens is derived from their uniqueness. As each of the non-fungible tokens is unique, each represents a value that is different from the other. It is not the same with other digital assets like Bitcoin or others where the value is the same and determined by demand and supply. Here the value is determined by the scarcity, rarity, and uniqueness of the tokens.
