If you're a developer keen on Blockchain development, you must be aware of NFTs (also known as Non-Fungible Tokens). In this post, you'll talk about the technology behind them to help you begin building your own.

When you finish the course, you'll be able to access your personal Ethereum wallet, with a brand new NFT within it. This tutorial is easy for beginners and doesn't require prior understanding regarding ethereum or smart contracts. Ethereum system or even smart contracts.

The NFT contract contains only fifteen lines of code

What Are the Reasons for Making an NFT?

When you mint an NFT then you issue the token in the blockchain. The token represents an example of the Smart Contract.

Each token is unique in its tokenURI. It contains metadata about your asset within a JSON file that adheres to some schema. The metadata is where you save details about your NFT including the name, image, description as well as other information.

A sample from the JSON file that is used to create"ERC721 Metadata Schema "ERC721 Metadata Schema" looks like this:

{

​

"attributes": [

​

{

​

"trait_type": "Shape",

​

"value": "Circle"

​

},

​

{

​

"trait_type": "Mood",

​

"value": "Sad"

​

}

​

],

​

"description": "A sad circle. ",

​

"image": "https://i.imgur.com/Qkw9N0A.jpeg",

​

"name": "Sad Circle"

​

}

How Can I Save the Metadata of My NFT?

There are three primary methods to store the metadata of an NFT.

In the first place, you can save the data on the blockchain. In other words, you can expand your ERC-721 to store metadata on the blockchain which is costly.

The other option is to make use of IPFS. Another option is to make your API provide you with the JSON file.

The first and third options are generally preferred because you are unable to alter the fundamental JSON file. In the context of this particular project, we'll choose the third option.

Why NFTs Cannot Be Copied Like Other Digital Products

Actually, NFTs resolve this problem by embedding an ID unique to the NFT (metadata) into the asset's token. After an NFT is created, it is registered on the Blockchain and its identity card, allowing users to view and verify the entire history of the asset (ownership creation, creator, and cost) with no need to use intermediaries.

Blockchain is a type of digital ledger that records transactions as well as the administration of smart contracts via an uncentralized network of computers and is free of the requirement for an intermediary. Here's a diagram of how it functions (applied to the Bitcoin transfer):

NFTs of Trade Shows, Live Shows, and Concerts

NFTs could also play a role in trade shows and other live events. NFTs can be used to track attendance at an event, verify the authenticity of event tickets, or provide a way to collect and redeem rewards earned at the event. 

NFTs could also create a digital passport to store information about an individual's attendance at different events. This would allow event organizers to track who attended their event and reward attendees with special privileges or discounts.

Are All These Transactions Worth It?

The possibilities for using NFTs are endless and could revolutionize e-commerce, online auctions, and trade shows. They can increase security and transparency for all transactions involved with these platforms while helping artists protect their work from theft or misuse.

NFTs can also provide a safe way to verify people's identities online and track participation at live events. They could also serve as a good way for event organizers to track who attended their events and reward participants with special perks. Using NFTs might even change the art world by ensuring that an artist's work is properly attributed. 

This industry is transforming e-commerce, online auctions, and trade shows.

What does the NFTs Market bring in?

NFTs open doors like:

• New Market

• Buyers are interested in Digital Art

• Supplies and demand is increasing

• Copyright for everyone

• Authentication in Art

New Models In Town! 3D NFT

3D NFTs are new entries in the NFTs industry. They are fresh and very demanding nowadays, also based on 3D models. 

Examples are 3D photos, gaming assets, and metaverse (which can change the gaming and financial Industry). With the help of a blender or any 3D tool, you can create these phenomenal assets.

NFTs Will Be a $2 Billion Industry By the End of 2022.

NFTs may be a new market for you, but the hunger is real. The market sells NFT art in the millions every year, and that stats chart speaks for itself. According to Forbes, they even broke records by selling art for about 69.3 million dollars. And now Cyberpunk 2077 also broke the records of 13 million sales at its launch.

Also, from DappRadar, the NFT industry generated 95 million dollars, and by the end of 2022, they will generate about $2 billion.

As I said, the stats speak for themselves. 

If you still don't believe in me, maybe you should consider Coca-Cola, Taco Bell, Nike, and Microsoft because they are investing in NFTs, which shows this is something more than hype.
