So, now that we have looked at how the genetic algorithm works, let’s go even deeper and take a look at their smart contract. This child genome is used to generate a new kitty.

It uses the crossover mechanism to “sire” a child genome using two parent kitties. This is done to make sure that the system can explore other possibilities for optimal solutions.Parent: 1010011000Child: 0101010001Ĭryptokitties uses the Genetic Algorithm to create a new kitty. Mutation: Mutation is when we take a parent and randomly mutate some of their variables to create a child.This is how a child retains certain features of the father and the mother.

So using our example:Parent 1: 1010011000Parent 2: 1001001010Child: 1000011010This pretty much works the same in real life as well. What happens here is that we choose the common variables of the two parents and retain those in the child solution. These well-performing parents are the ones that are preferred for reproduction.

Selection: Selection basically means retaining the best-performing parents from one generation to the next.

cases where the genes can be represented as 1’s and 0’s. So let’s take a look at how evolution works using genetic algorithm. While the genes inside our body consist of proteins and various other elements, in GA they are represented via numbers. The algorithm then generates subsequent solutions from these parent solutions using bio-inspired operators like selection, crossover, and mutation. It starts with an initial generation of candidate solutions that have been tested against the objective function. It works pretty much the way biological genetics works. The genetic algorithm is an optimization technique used to solve nonlinear optimization problems. Which is carried down to all its descendent kitties via the use of Genetic Algorithm. In fact, even Vitalik has gotten in on the act!Įach kitty has its own unique 256-bit unique genome code. Several articles have been written about the “kitty phenomena” and they have received significant mainstream exposure as well. Let’s look at how many sales have been made per day: There are even reports of people who have made more money trading cyptokitties than investing in their IRA! People have spent more than twelve million dollars buying these cryptokitties. Sales of Cryptokitties have been through the roof. However, what is truly important to remember is that this is the first known application of DAPP for leisure and recreation. The game was made by Vancouver based blockchain company Axiom Zen. Cryptokitties is a blockchain-based virtual game that allows players to adopt, raise, and trade virtual cats.
