Non-Fungible Token

What NFT is and How it Works?

NFT stands for a non-fungible token, which means it can neither be replaced nor interchanged since it has unique properties. As a matter of their uniqueness, NFTs are irreplaceable. Each has a digital signature which made the exchange of NFTs impossible for one another. For example, cryptocurrencies can be traded or exchanged for one another and they’re equal in value; you can trade off a bitcoin for another unit as they are not identifiable, but NFTs are unique assets, each has got its characteristics and structure. To simplify this, consider the following example:

If you borrow your friend's car for a while, you have to return the same car in due time, not a different one, now if you borrow some Ethereum from him/her, you are supposed to return the number of the same units at the time of delivery; Thus in non-fungible tokens, the main issue is nature of the ownership, not quantity and number. Note that this is a relative exchange. Below we will discuss more the general format of these exchanges.

Main Features of NFTs


The uniqueness of non-fungible tokens let the issuers to prove ownership of their digital assets. NFTs have distinct personalities. These assets include photos, videos, artwork, property, or event tickets that have become digital assets.


Ownership of non-fungible tokens sets down on the blockchain. The registered information on the blockchain is shared between all users connected to the blockchain network and manipulation of them is impossible, an attempt to make a change in the information of each Block results in the invalidation of the next block’s hash. Therefore, the recorded information is highly secure for the owner of NFTs.


Most NFTs cannot be split into smaller denominations; one cannot trade-off or transfer a fraction of NFTs.

What is the structure of NFTs?

NFT was first introduced in the Ethereum Development Statement. It was later developed in the EIP-1155 Multi Token standard. As a result, currently Ethereum Blockchain is the first and the best marketplace for NFTs.

ERC-721 Non-Fungible Token Standard

The ERC-721 (Ethereum Request for Comments 721), proposed by William Entriken, Dieter Shirley, Jacob Evans, and Nastassia Sachs in January 2018, is a Non-Fungible Token Standard that implements an API for tokens within Smart Contracts. This standard specifies the ownership of each token for each address and the portability.

• ERC-1155

The ERC-1155 standard allows you to create both interchangeable and non-interchangeable tokens. This standard is applied in computer games as well. For instance, specific numbers like 1000 of an item such as a weapon are offered to players. Unlike ERC-721 which each token is unique and belongs to only one person, in contrary, by this standard, you can divide the same number of items between different addresses.
