Crypto Academy Week 10 - Homework Post for @levycore

In this homework, i am going to describe one popular project that uses Non Fungible Token ( NFT). But first, what is a Non Fungible Token?

"A Non Fungible Token is a unit of data stored on a digital ledger, called a blockchain, that certifies a digital asset to be unique and therefore not interchangeable". Source
This means that there is only a single official owner and you cannot interchange it. Now, you can use Non Fungible Token (NFT) to represent a lot of things like games, music, photos, videos, and any digital files you wish. One popular project that uses NFT is the Cryptokitties.

Cryptokitty is actually a blockchain game that operates on Ethereum blockchain. Normally, one plays a game for recreation and leisure and that is what cryptokitties are meant for. They are meant for recreation and leisure. "Cryptokitties are digital representations of cats with unique identifications on Ethereum's blockchain. Each kitty is unique and has a price in ether. They reproduce among themselves and produce new offspring, which have different attributes and evaluations as compared to their parents". Source

This means that a player is allowed to buy a kitty and that kitty is unique which means that it cannot be replicated, it has its own distinctive features. The user or owner can interact with the kitty and even sell if so desired. If that kitty is going to be transferred to another user, it must be with the express permission of the original user. The blockchain validates each user. Now, bearing in mind that the virtual cats are tokens on a blockchain, they can be bought, sold or transferred digitally. You can create more cryptokitties by breeding existing ones.

The virtual cats are breedable and carry a unique number. There are a total of 12 different attributes that any cat can pass to the offspring. They include: pattern, mouth shape, fur, eye shape, base color, accent color, highlight color, eye color, and optional wild, environment, purrstige, and secret. Sourced

Now what is the technology behind cryptokitties? "A cryptokitty's ownership is tracked via a smart contract on the Ethereum blockchain. Each cryptokitty is represented as a non fungible token using the ERC - 721 token standard on Ethereum". source

In conclusion, i will say that cryptokitties game has really gained much poularity which was noted in December 2017 that even led to the congestion of the Ethereum network thereby slowing it down.
