# Model Overview

In Balancer V2.0 Simulations , we will show some real-world transactions that can be called through the Balancer simulator model. Additionally, by using python instead of solidity, we have been remove expensive gas fees while deploying contracts. 

In order to verify the accuracy of our model we have used real-world transaction data to generate accurate and credible results. 

In order to maintain constant practice throughout our files, we are following the cadCAD system model with:

* State Variables to describe the state of the pool
* State Update Functions, that update the variables according to various events such as transactions and price updates
* Policy Functions that define the rules of our system 
* Partial State Update Block which are the state updates and policy functions 

Simulations in V2.0 allows for: 

A) Analysis of an on-chain transaction data of a Balancer pool in the format of a series of transactions in a json file. 

B) Adding information about token prices in USD and analysis of arbitrage opportunities or metrics such as the Total Value Locked (TVL). 

C) The general model of the Balancer Pool V2 

D) A jupyter notebook to tie together all of the components, allow for easy and coherent analysis of charts and in order to draw reliable conclusions
