1. As said above cryptokitties uses a genetic algorithm. This algorithm works as similar to Bio - Genetics. Whereas the genes represent our eye color, hair color and a lot of stuff. Just like that the genetic algorithm in cryptokitties represent the background color, body color, eye color, mustache, fur patterns, expressions, tails and lot more

2. For every 16 minutes the network release new gen0 kitten by developers, when a newly released kitty gets high bid then the developer gets the total value of the bid. This is time by the crypto kitty network, just to encourage the developers in order to create new kitties 

The Genetic algorithms in cryptokitties, let the mating cats, create a new kitten and with a new genome. The newborn crryptokitty will have the cattributes based on its genome Id. This entire process has been written in smart contracts, so far every unique genome ID, it creates new kitty with new cattributes.

Hope you had a basic idea about cryptokitties, Let’s discuss how to build a dapp like cryptokitties and which blockchain is most preferable. 

How to build a dapp like cryptokitties?

You can create a dapp like cryptokitties in two ways. 

  • Using the open source code 
  • And by leveraging a blockchain like TRON Which favors creating entertainment-based dapps.

Using Open Source Code:

You must have some basic development skill to understand the cryptography algorithm and must have the basic knowledge to develop a dapp in the blockchain.

Skills required : 

  • Expertise to handle Development tools 
  • Must be capable of writing smart contracts and auditing it.
  • UI/UX Design
  • Testing skills

Steps to Create a dApp in Ethereum 

  • Create an account on ethereum dapp
  • Setup dapp development tools
  • Review the smart contracts of cryptokitties
  • Code  your own smart contracts 
  • Test, and Run Your Smart Contracts

Cryptokitties smart contracts can be divided into smaller as below

KittyAccessControl  - This contract defines who is having full access control over a kitty

KittyBase - it defines the attributes of a kitty like a birth time, Gene Code.
Kittyownership - This defines the kitties as tokens, these tokens are fungible tokens and are written on ERC721. The ownership of a kitten is tangible.
Kittybreeding - This Contract used while the players breeding a kitten.

Genescience- the core concept of the crypto kitty hold by this smart contract. (i.e) The fun of the game is making a new breed. If the gene codes are open to everyone, then anyone can make a rare breed by comparing it with other kitty code. So the fun will get reduced, and will not excite the users. So the Creators made it a closed contract.

KittyAuctions: It has the detail of buying and selling of kittens through smart contracts.

KttiyMinting: This contract defines the opportunities of creating gen0 kittens.

Kittycore:This is the core contract, which combines everything together to work properly
