How To Create An Nft On Opensea


We saw a boom in the NFT space in 2021. This is a concept that was preconceived in 2012 as “THE COLORED COINS CONCEPT” 

Colored Coins were regular Bitcoins, but each had a mark on them, that determines what it is going to be used for. In essence, each of them was the same but served different purposes thereby making them unique.

The Colored Coins concept could never be realized because of the limitations of Bitcoin, however, it did lay the foundation for the experiments that led to the invention of NFTs.

The concept of NFTs came to the limelight when Ethereum was backed up with the introduction of a set of token standards, allowing the creation of tokens by developers. 

The token standard is a subsidiary of the smart contract standard, including; informing developers on how to create, issue and deploy new tokens in line with the underlying blockchain technology.

Today, the mere unrealistic concept has become a widely known technology that a lot of people have made money from.

NFT is an acronym for “NON-FUNGIBLE TOKEN”

A fungible good or item is an item that’s mutually interchangeable with another item. The value of this item is universally accepted to be equal. 

For instance, I can exchange my 100 dollars note with two 50-dollar notes anywhere it’s accepted. The two 50 dollars notes hold the same value as the 100-dollar note. 

You’ll agree with me that non-fungible is the opposite of fungible, therefore, non-fungible goods are not mutually interchangeable. They are one-of-a-kind (Unique), an example is a vehicle. 

Two Prado jeeps parked at a car stand auctioned for sale, one pre-owned by Dangote and the other by a young guy. 

You’ll agree with me that the car pre-owned by Dangote will have a higher price tag than that of the guy irrespective of the fact that it’s the same model of car. This is because the value of the two cars is perceived differently.

Now, what is a token? A token could be said to be a digital certificate stored on a secured and distributed database called “Blockchain”.

A non-fungible token (NFT) is a token that possesses a unique identifier and has additional parameters that allow you to store certain information on it. That unique identifier is what makes a token non-fungible. The additional information can be any information such as text, images, audio, and video files.

Why Opensea?
