Bitcoin brought about the notion of a trustless digital shortage. With the introduction of blockchain technology, the digital shortage has become possible. The technology is being used to link the real world with the digital. The concept of non-fungible tokens (NFTs), is similar. It is a type of cryptographic token that represents a unique asset. The assets can be fully digital or tokenized versions of real-world assets. An NFT's worth is determined by its quality, scarcity, and, most importantly, rarity.
NFTs are non-fungible as they can't be duplicated. Each NFT has a unique identity and is proof of ownership. NFT owners are registered on the blockchain. The data is secure and immutable. NFT can therefore be traded to replace the digital asset it has been tagged in.
NFTs are an essential building block for a Blockchain-enabled, digital economy. Its popularity continues to rise every quarter. It was $13.7million for the first half of 2020 and is now $2.5billion in 2021. A buyer had bought an NFT with nine plots of Genesis land within Axie Infinity virtual universe on February 8th, 2021. Its value was $1.5million at the time it was purchased. The sale was regarded as the largest digital land transaction. In the years ahead, virtual economies are expected to be the norm in a digital world that is rapidly evolving.
What are Non-Fungible Coins?
- What it is: A nonfungible token is a cryptocurrency asset that is unalterable and unique. It can represent an intangible digital product such as a video or image or an in-game item.
- What it isn't: The NFTs are not interchangeable. Each NFT represents a unique digital asset, which can be bought or sold in an open market.
The intrinsic property to be interchangeable is the difference between fungibility and non-fungibility. Fungibility can be defined as a commodity's or asset's intrinsic property to be interchangeable. Gold and fiat currencies can be used interchangeably with each other as fungible products. One example is a five-dollar bill that can be exchanged with another five-dollar note. It is the desirable characteristic of currencies that allows for free exchange. It isn't beneficial for collectible items. It doesn’t give any way to trace the product’s history.
Bitcoins are fungible tokens. It is possible to exchange one bitcoin for another. However, it will still remain one bitcoin. However, depending on when the Bitcoin was exchanged, its value might vary. Additionally, you can exchange Bitcoin for Satoshi. Fungible tokens are also divisible.
non-fungible tokens contain identifying information saved in Smart Contracts. These data make NFTs distinctive and indistinguishable from one another. The indivisibility and ineligibility of NFTs can also be described as the inability of you to share or send a piece of your concert ticket. The fractional ticket is unredeemable and is not worth anything.
CryptoKitties is one of the earliest NFTs. Every CryptoKitty is unique. There are two types of CryptoKitties: one is sending someone a CryptoKitty; the other is receiving one.
What are the characteristics of an NFT?
Unique: NFTs can be unique. Smart Contracts that are associated with each individual unit record permanent identification data. It functions as a certificate of authenticity.
Indivisible: NFTs cannot split into smaller parts. You cannot, for example, divide a digital artwork piece or a football ticket into smaller pieces. You can buy it all, or you can get nothing.
NFTs are rare: NFT's rarity and scarcity determine their value. While developers could create as many NFTs as they like, it is not common for them to be limited in their rarity.
What are NFT Standards, you ask?
The following token standards have been created to support NFTs.
ERC-721 Standard
It was the original standard that allowed for the representation of non-fungible assets. It is an inheritable Solidity Smart Contracts standard. Open Zeppelin can be used to create compliant contract designs by developers.
ERC-1155 Standard
The ERC-1155 standards introduce semi-fungibility into the NFT industry. It provides a superset of the ERC-721 Standard, i.e. ERC-721 assets could also be built using this standard.
