What Is NFT: Exploring Non-Fungible Tokens & Their Impact

Non-fungible tokens (NFT) cause a sensation in the cryptocurrency market in 2018. It is enough to recall the CryptoKitties and all the hype around them. But what is NFT? Let’s try to figure that out.

Why Do We Need NFT?

Fungible cryptocurrencies represent the majority of tokens on the crypto market. Fungible tokens are digital assets built so that each individual token is equivalent to the next and easily can be interchanged. For example, one Bitcoin is no different from another Bitcoin. And if you will get a certain amount of BTC it will not matter which manner produced the coin. It will still have the same value.

However, not so long ago, a new type of tokens appeared — non-fungible ones. Their main feature that they are not interchangeable with tokens of a similar type.  Every token is rare and has unique attributes and as a result, has different values.

Non-fungible tokens are used to create verifiable digital scarcity, as well as player ownership, and the possibility of asset interoperability across multiple games. NFTs are used in several specific applications that require unique digital items like crypto-collectibles and crypto-gaming.

NFT Platforms and Standards

The most popular platforms for creating NFT tokens are Ethereum and WAVES. Today most tokens are issued on the basis of the following standards:

  • ERC-721 based on Ethereum features a set of standard functions and attributes that define it, in the form of a smart contract. Simply put, ERC-721 provides us with a standard to create and exchange Non Fungible Tokens. ERC-721 standard was proposed by Dieter Shirley in September 2017.
  • ERC-1155 protocol is an improved and better version of the ERC-721, which offers many new features for creating NFTs. The main feature of which allows you to perform more than one complex task in a single transaction. ERC-1155 was proposed by Witek Radomski (Enjin Co-Founder & CTO) in June 2018.


In November 2017, on the wave of crypto excitement, the Canadian company Axiom Zen released a game based on the Ethereum blockchain — CryptoKitties, the essence of which was to breed digital cats. This is a game similar to the idea of Tamagotchi, which appeared in 1996. In Tamagochi users were given a virtual pet in order to watch his life from birth to death, help him cope with diseases, hunger and thirst. In cryptocurrencies, its also virtual pet but instead of cleaning up after it, users can breed, sell and buy new pets.

In December 2017, the game CryptoKitties gained viral popularity — in a few weeks, users spent more than $23 million on it, and at the peak of popularity, the game occupied 15% of all traffic on the air, while crypto-cats were sold for $100.000 apiece, and the total cost of transactions exceeded $40 million. CryptoKitties has become the world’s most popular case of using the Ethereum blockchain outside of the cryptocurrency exchange.

The history with CryptoKitties has shown that non-fungible tokens are a promising technology, and in addition to entertainment, it allows you to digitize the ownership of land or real estate, certificates, notaries, tickets or voting rights. So it may only be a matter of time until a non-fungible token becomes as sought-after as leading cryptocurrencies.
