How do NFTs workIf you want to know about How do NFTs work? This article is for you that paved the way to understand the working style of NFTs.

NFTs are tokens that we can use to represent ownership of unique items. They let us tokenize things like art, collectibles, even real estate. They can only have one official owner at a time and they’re secured by the Ethereum blockchain – no one can modify the record of ownership or copy/paste a new NFT into existence.

NFT stands for non-fungible token. Non-fungible is an economic term that you could use to describe things like your furniture, a song file, or your computer. These things are not interchangeable with other items because they have unique properties.

How do NFTs work?

It’s not hard to understand that how do NFTs work. However, NFTs are different from ERC-20 tokens, such as DAI or LINK, in that each individual token is completely unique and is not divisible.

NFTs gives the ability to assign or claim ownership of any unique piece of digital data, trackable by using Ethereum’s blockchain as a public ledger. An NFT is minted from digital objects as a representation of digital or non-digital assets. For example, an NFT could represent:

Digital Art:

  • GIFs
  • Collectibles
  • Music
  • Videos

Real-World Items:

  • Deeds to a car
  • Tickets to a real-world event
  • Tokenized invoices
  • Legal documents
  • Signatures

Ownership of NFTs

An NFT can only have one owner at a time. Ownership is managed through the uniqueID and metadata that no other token can replicate. NFTs are minted through smart contracts that assign ownership and manage the transferability of the NFT’s. When someone creates or mints an NFT, they execute code stored in smart contracts that conform to different standards, such as ERC-721. This information is added to the blockchain where the NFT is being managed. The minting process, from a high level, has the following steps that it goes through:

  • Creating a new block
  • Validating information
  • Recording information into the blockchain

NFT’s properties:

Each token minted has a unique identifier that is directly linked to one Ethereum address. They’re not directly interchangeable with other tokens 1:1. For example, 1 ETH is exactly the same as another ETH. This isn’t the case with NFTs. Each token has an owner and this information is easily verifiable. They live on Ethereum and can be bought and sold on any Ethereum-based NFT marketplace.

If you own an NFT:

You can easily prove you own it. Proving you own an NFT is very similar to proving you have ETH in your account. For example, let’s say you purchase an NFT, and the ownership of the unique token is transferred to your wallet via your public address.

The token proves that your copy of the digital file is the original. Your private key is proof-of-ownership of the original. The content creator’s public key serves as a certificate of authenticity for that particular digital artifact.

No one can manipulate it in any way. You can sell it, and in some cases, this will earn the original creator resale royalties. Or, you can hold it forever, resting comfortably knowing your asset is secured by your wallet on Ethereum.

What if you create an NFT?

If you create an NFT, You can easily prove you’re the creator, you can determine the scarcity of your NFTs. By creating NFTs you can earn royalties every time it’s sold. You can sell it on any NFTs market or peer-to-peer. You’re not locked into any platform and you don’t need anyone to intermediate.

Characteristics of NFTs

Unique – Deep inside a non‑fungible token, metadata describes what makes this asset different from all the rest. This is a permanent, unalterable record that describes what this NFT represents — almost like the certificate of authenticity that you’d get with a rare painting.

Rare – Scarcity is an important ingredient in the recipe that makes NFTs so attractive. While developers have the freedom to generate an infinite supply of certain assets, they also have the power to limit the number of rare, desirable items in existence.

Indivisible – For the most part, NFTs cannot be split into smaller denominations — they can only be bought, sold, and held whole. Remember the rules of non‑fungibility: you can’t purchase 10% of a plane ticket, or collect 50% of a baseball card.


Some analysts anticipate the NFT market will exceed $1.3 billion by the end of 2021 as more artists, brands, and icons join the space to create their own distinctive tokens. With more blockchains competing to produce better NFT services too and a growing range of platforms to choose from, now is a great time to take part in the space.
