# oracle

## Purpose

{% hint style="info" %}

{% endhint %}

\
The purpose of the price oracle is to balance the payout of $GOLD earned through mining with the cost of minting the current USD value of $GOLD.\
\
This means that if the dollar value per $GOLD increases, the following will happen:\ <br>

* $GOLD spend less<br>

* Mint Hero Costs Less $GOLD\
  \
  If the price of $GOLD USD decreases, the above situation is reversed.\
  \
  The oracle will dynamically adjust costs and rewards based on changes in the dollar value of $GOLD.\ <br>

* ## Reason

  The reason for using an oracle is to keep the game's economy balanced around a set dollar value. There is a limited amount of $GOLD tokens that can be circulated in the economy, and an influx of players could exhaust all $GOLD tokens present in the game contract.\
  \
  Through the use of oracles, Dragon War establishes a connection between active users and the dollar value of $GOLD. The assumption is that when the price of $GOLD rises, demand for $GOLD also increases with the release of new game features or an influx of new players. The oracle ensures that each transaction pays a consistent dollar value at the time of the transaction, while also ensuring that the minting cost of NFTs maintains a consistent dollar value\
  \
  This means that entry costs and rewards can be balanced and maintained over the long term, and will accurately reflect the required minting costs to give new players a chance to play even as the dollar value of $GOLD increases.
