# Node Runners: Doing Inference and Earning $NES

> ⚠️ **Evaluation in Progress**
>
> Some of the mechanisms described on this page are currently **being evaluated and validated**. They represent design options under consideration, and may be refined, replaced, or omitted as the system evolves.

Node runners contribute to the decentralized and distributed nature of Nesa, enhancing its efficiency and security for running AI models. They can be run by individuals, companies, or any other entities interested in supporting the network and earning rewards (which is [$NES](https://docs.nesa.ai/nesa/background-and-exploratory-notes/broken-reference)) for their efforts.

These nodes support the network by performing several critical functions:

1. **Validation**: Nodes validate new transactions and blocks to ensure they follow the network rules. This includes checking that transactions are properly signed and that they do not attempt to spend funds that have already been spent.
2. **Inference**: Node runners execute the actual inference task assigned by the orchestrator, where the aggregated results will be returned to the user who request the job.
