NFTs, short for Non-Fungible Tokens, are taking the world by storm. A lot of celebrities and well-known personalities are displaying their NFTs as their profile pictures on social media platforms.

Mainstream brands, such as Nike and Adidas, have entered the space.

With the growing popularity of NFTs, it is becoming very hard to ignore this rising popularity.

So, what exactly are NFTs? Are they important to the upcoming Web 3.0 iteration?

What Are NFTs?

NFT is short for Non-Fungible Token. They are crypto tokens that are unique. They represent a non-interchangeable set of metadata that is stored on a blockchain.

Some of the most popular examples are Ethereum and Bitcoin.

A single bitcoin is equivalent to a single bitcoin. Users are indifferent between the exact bitcoin they’re getting or buying.

Every NFT is uniquely identifiable. On almost every occasion, users will care about the exact NFT that they’re getting or buying.

Blockchains are digital ledgers that are decentralized and distributed. They’re made up of blocks of data that are chained together in chronological sequence.

Ethereum is the most commonly utilized blockchain for NFTs. People are beginning to see the rise of niche blockchains as well. This includes Ronin and Flow which are built with gaming and NFTs in mind.

The metadata for the NFTs is located in smart contracts that are stored in the blocks on a blockchain.

One common myth about NFTs is that the JPEG or image displayed that represents the NFT is stored on the blockchain.

Though that’s true for a minor handful of projects, most projects store the image on an external storage platform. The metadata on the blockchain contains the link to that photo.

The cost of storing a photo on the blockchain is very high because of the file size of the image. This makes it uneconomical for projects to be completely on-chain.

Can You Create an NFT?

There are many methods to build NFTs. You can do it with the help of systems or do it manually.

Rarible and OpenSea are some of the most common areas to help people create NFTs.

Beyond the technicalities of creating an NFT, one vital thing to think about is the blockchain you want to build your NFT. This includes Polygon, Avalanche, Solana, Ethereum, and more.

Various blockchains have various trade-offs and communities that can have a huge influence on the success of your project.

OpenSea has an excellent guide on how to create your NFTs easily on Ethereum using their platform.

How to Purchase an NFT?

The biggest marketplace is OpenSea in terms of transaction volume. There’s a huge possibility that it’s where your NFT journey starts.

Though most well-known NFT collections are available in the Ethereum blockchain, there are also other NFT choices available in other Blockchain networks. This includes Polygon, Terra, and Solana.

Other well-known marketplaces are Rarible and LooksRare for Polygon/Ethereum, Random Earth for Terra, and Solanart and Magic Eden for Solana.

You’ll have to set up a crypto wallet. It should be compatible with the blockchain that the NFT project is built on to interact with the marketplaces.

The most commonly utilized wallets are Terra Station for Terra, Phantom for Solana, and MetaMask for Ethereum.

Once you set up your wallet, transfer LUNA/SOL/ETH to the wallet from a centralized exchange of your choice and you are good to go.
