how nft works

It’s crypto 2021. Cryptocurrency is in and all shopping centers and dealing authorities have become online. Bitcoin is blooming over $50,000. PayPal has accepted Bitcoin, Litecoin, Ethereum, and Bitcoin Cash. But the most interesting type of blockchain called the non-fungible token or NFT is increasingly in demand and selling up to $69 million. How NFT Works. Recently, NFTs are empowering the world art collection. They serve as proof of ownership of an original piece of valuable art, which is mainly built on trust. Now NFTs are considered superior to the current paper system of art ownership or copyright for many investors and art collectors. So, what do you think of what is NFT? Let’s overview some basic definitions of terms associated with NFTs. 


NFTs stands for “non-fungible tokens”. An NFT is a digital asset that links ownership to unique physical or digital items like artworks, photos, real estate, music pieces, video clips or more. So NFT can represent a painting, a trading card or even a house. Generally, NFTs are units of data stored on a blockchain digital ledger. It is a kind of certificate of authenticity and ownership. An NFT is unique, non-interchangeable, can never be adjusted and can never be stolen. NFTs use the cryptocurrencies blockchain technology to work. NFTs are modern-day collectibles, which have been bought and sold online.

Digital asset 

A digital asset is anything that exists in a computerized format and has a right to own, for example, a right to copy, reproduce, modify, duplicate and otherwise use. All the things whether computerized documents, photos, audio or visual content, images or other similar digital data (e.g., JPGs, GIFs, MP3s and MP4s) are all digital assets.


A blockchain is a type of database, but unlike a basic database, it is a series of data blocks that are linked together like a chain. A blockchain creates a shared digital ledger and records the activity and information in blocks within the chain. Each blockchain ledger is further stored globally across thousands of different servers, shown by everyone. This peer-to-peer technology facilitates the process of recording and tracking transactions of digital assets and is nearly impossible to falsify or tamper with data. 

Non-fungible tokens vs Fungible tokens

Physical money and cryptocurrencies both are fungible in the sense they can be traded or exchanged for one another. They’re also equal in value like one dollar is always equal to another dollar and similarly, one Bitcoin is always worth another Bitcoin. While Non-fungible means that it’s unique and can’t be replaced with something else. A one-of-a-kind trading card, an NFT, is non-fungible.

Non-fungible tokens vs cryptocurrency

Even though both are based on blockchain technology, the key difference is cryptocurrency being fungible. So a Bitcoin can be exchanged for another Bitcoin. However, you cannot do so for an NFT. A non-fungible token is strictly bound to one particular digital asset and cannot be replaced. 

What can NFTs be used for? 

The uses of NFTs become more and more fascinating and valuable. They are mainly used as tickets and tokens. They are ownership certificate of fashion-oriented, Luxury or counterfeit goods. People have always enjoyed collecting memorabilia, trinkets, and other similar items. NFTs provide a way of ensuring authenticity, a kind of digital signature or stamp of approval.  NFTs can be a prototype of a painting, photo, music, video or real estate. Recently, NFTs has also entered the game industry and provide gamers with a way of owning unique in-game items.

How do NFTs work?

Generally, NFTs are created and stored on the Ethereum blockchain, yet other blockchains such as Flow, Solana and Tezos also support NFTs. Anyone can review the blockchain and the NFT ownership can be easily traced and verified with no change in information or entity.

An NFT has only one owner and this ownership is controlled through a unique ID and metadata which can never replicate. These NFTs are minted through blockchains. Smart digital contracts have been made that assign ownership and manage the distribution of the NFTs. When user creates an NFT, they execute some codes stored in smart contracts given as different standards, such as for Ethereum it can be ERC-721. This information is then added to the blockchain where the NFT is being minted.

All types of digital goods can be created as NFT including artwork, images, game, stills or video from a live broadcast, music pieces, collectibles, cards, memes or famous tweets of known personalities. The file size of the original digital item, for which an NFT assigned, doesn’t matter because it remains separate from the blockchain.

Exclusive rights or limited-edition print to the NFT depends on the type of NFT or the copyright or licensing rights granted by NFT creator. NFT creators can also create shares for their NFT. Thus creators, investors and fans have the similar opportunity to own a part of an NFT without having to buy the whole item.

Can NFTs be replicated or printed?

You can copy a digital file as many times as you want and also the same for an NFT. But NFTs have something that can’t be copied and this is indeed ownership of the work. So, anyone can buy a Monet print but only one person can own the original. Today almost all NFTs have been viewed online but not all artists give permission for them to be printed. That’s why, unlike a physical work of art, it isn’t confined to one form created by art specialists.

Do NFTs have to be original?

The truth is, NFTs are just tokens that represent an asset completely separate from the original assets themselves. Because every NFT represents a unique original asset, a single NFT can’t be duplicated while maintaining the same value as the original. As art prints of an original are made, used or traded, the same way NFT’s are valid and original parts of the Ethereum blockchain. So, they are individual tokens with extra information stored in them that can be used and traded.

Ethereum Addresses in crypto wallet MetaMask

Making Ethereum addresses is done by Ethereum Name Service (ENS). Which uses NFTs to provide your Ethereum address with an easier-to-remember name such as fbwallet.eth or walletme.eth. So, seller will ask the buyer to send ETH via ENS name rather than complex codes or digits like ABC123456789. There are many other crypto wallets as well but the easiest way to make an ENS name is to use “MetaMask”, having an Ethereum wallet. With your wallet, you will be able to send and receive ETH, thus it is an NFT business account. You can download MetaMask free app on your iPhone or Android smartphone.

Does minting an NFT cost money?

Yes, there is a payment known as a gas fee required, when you mint your NFT before you can list it.  This is not like a commission rather it is a cost to mint an NFT due to network transaction fees which are necessary for sending all transactions on the blockchain. These transaction fees vary by network and NFT platform you used. If using an Ethereum-based blockchain like OpenSea, it will be ETH gas fees, but for others like BakerySwap, it will be BNB gas fees. There can be $100 USD just to mint an NFT on Ethereum while non-Ethereum options can be cheaper but with less exposure. An analyst Nerds Chalk shared that the least payment to mint an NFT is about $70 on Ethereum blockchain. According to other crypto analysts, minting a digital artwork to NFT can be often free to between $70 to $100. However, you will pay a gas fee based on the final sale price of your NFT, which could be 2.5% of final sale value.

And both are getting benefits from every trade of these NFTs cards.

How much is an NFT worth?

Photographers, musicians, filmmakers, and gamers are going out of their way to churn out NFTs. The simplest way to explain the worth of NFTs is to compare them to some physical products.

Meanwhile, the industry is in its early stage but has a great potential to get into the mainstream. NFTs convert assets into tokens so that they can move around within this modern system. This uniqueness has to completely transform markets like property, vehicles, accessories, special items, secret things, costly and complex assets. Similarly, if most of our lives will have to spend in virtual worlds in future, probably the things that we could buy be bought and sold as NFTs.
