But first, let us brush up on some of the basics of NFTs and why you will need a marketplace like OpenSea to access them.

What are NFTs?

Ever since bitcoin has been launched in the year 2009, lots of people have been used to buying and owning assets that exist only on social media.

With blockchain as the underlying technology, cryptocurrency is also a way to own and transfer value on the internet without having to involve a third party.

Interestingly, NFTs build on this functionality to create new possibilities centered around the uniqueness of digital assets.

Whereas crypto assets like bitcoin and other are fungible, or exchangeable, NFTs, All thanks to blockchain technology, which allows digital assets that are verifiably unique and unexchangeable.

In other words, NFT can represent digital art, an in game asset, music or any other item that requires a system for authenticating its uniqueness, rareness and ownership status in the digital realm.

NFTs also provide the much needed non fungibility for bringing unique digital assets and real-world assets to the blockchain.

The ownership of an NFT can be transferred in exchange for digital currencies without involving third parties.

However, for this to happen, interested buyers and sellers must perform this task on a platform specially designed to allow the listing, buying and selling of NFTs. These platforms are called NFT marketplaces.

Regardless of the controversies surrounding OpenSea’s operations, it remains the largest NFT marketplace, with over $3.5 billion worth of Ethereum-based NFT trades processed in August 2021 alone.

To put this stat into perspective, OpenSea posted just $20 million worth of NFT trading volume for the entirety of 2020.
