# Price Module (Oracle)

The Price Module provides asset prices to the network through each node, calculates the average price and provides it to the blockchain network to calculate the weight of consensus rewards, and provides asset prices to other application modules in the network.<br>

Each consensus node is required to provide accurate price feeds based on the average prices from multiple exchanges, oracles, or pricing agencies — similar to an index mechanism. The data submitted by these distributed nodes is used to calculate a Price Feeding Index, which determines the weight used for staking and mining rewards.The price feeding index is updated daily, and the results are recorded on-chain.

The calculation process includes:

* Eliminating the two highest and two lowest submitted prices to remove outliers.
* Averaging the remaining prices from all participating consensus nodes to establish a fair market reference.
* Based on the price feeding index, the system determines staking and collateral mining weights for supported assets. The weight distribution is calculated in proportion to the market value of each accessed token.\ <br>
