# Nodes

**Node Responsibilities with Incentive Calculations**

**Storage Node Incentives**:

* Rewards depend on storage commitment and duration.
* **Reward Formula**:

*Reward=base reward×storage capacity×duration*

```solidity
function calculateReward(uint256 baseReward, uint256 storageCapacity, uint256 duration) public pure returns (uint256) {
    return baseReward * storageCapacity * duration;
}
```
