Everything You Need To Know About Non-Fungible Tokens (NFTs)

Non-Fungible Tokens or NFTs and its various applications in the realm of art, gaming, even real-estate makes it to be the next big thing in blockchain technology.

Utility tokens, security tokens, cryptocurrencies and their classifications keeps evolving with newer technologies and better modifications.

As people are getting themselves familiar with Bitcoin and other cryptocurrencies, there is another classification of digital asset that is slowly starting to get its momentum.

Non-Fungible Tokens is one such example of this evolving fast-paced blockchain industry.

But ever wondered what are actually NFTs? How do they work? What exactly are they used for and What are some of the best NFT projects?

In this guide, we will explore all things on NFT!! on what exactly they are, how do they work, and its various applications within blockchain technology.

What Does Non-Fungible Mean?

In order to understand fully on NFTS, one needs to have the basics cleared up on the difference between “fungible” and “non-fungible”.

Fungible, in case of a token means something which is easily replaceable and interchangeable.

Fungible, for example could include a 1$ dollar bill that you currently have.

In this case, it doesn’t actually matter whether you will not receive the “exact” bill if you lend it to someone.

Non-fungible is the opposite spectrum here, in a way that even if a certain product seems or looks identical, each will have unique information making it almost impossible to be replaced.

A plane ticket is a perfect example of a non-fungible asset. Even though they look or seem similar, each ticket contains unique information different from the other tickets such as the name, seat numbers, destination, etc.

Before we explore NFTs further, two terminologies needs to be understood properly before we dive into the rest of the article:

  1. Smart Contracts: Smart contract is a set of automated executable protocols intended to facilitate and enforce the negotiation of a contract.

  2. Token: Tokens are tradable assets or utility on a blockchain whose specific properties are designed accordingly to its usage.

What Can Non-Fungible Tokens Be Used For?

The most well-known form of non-fungible tokens are collectibles on blockchain.

One of the earliest pioneers of non-fungible is the well-known CryptoKitties, a blockchain platform where players can breed and collect digital cats.

A cat owner will know that cats are not replaceable as their personality and appearance makes them unique.

CryptoKitties ideated the same concept with digital cats with each cat’s genetic material stored on the blockchain platform.

The cats could be bought and sold through Ethereum ranging up to $12,000.

Similar games such as fantasy titles too followed the same suit where fighters are collected for battles.

How Are NFTs Made/Created?

Different standards exist for non-fungible tokens, the first one being ERC-721, similar to the common ERC-20 tokens.

ERC-721 tokens are driven by smart contract code embedding the unique details making them rare or desirable. This metadata could then be stored on the blockchain both or off.

Other standards take NFTs one step ahead. For example, ERC-1155 tokens are used to develop fungible and non‑fungible tokens.
