# Step 4.1 Network selection

**Start by selecting the network where you want to set up your node**

* **Ethereum Mainnet:** Ethereum Mainnet is the primary production network of Ethereum. Running a Stader Node takes some know-how and resources, but it also offers significant rewards and benefits for those who contribute to the network's security and scalability. You will be using real ETH and SD to run a node on Ethereum mainnet. If you're ready to take on this challenge, Ethereum Mainnet welcomes you!
*   **Goerli Testnet:** Goerli is a test network that provides a secure and zero-cost environment for executing Stader Node operations. By choosing this network, you can create Demo node and validators using testnet ETH and testnet SD. [_Learn more_](https://goerli.net/)
