NEAR Protocol runs on a collection of publicly maintained computers (or "nodes"). All nodes are running the same
nearcore codebase with the latest releases available on Github. In the following section, we will introduce three types of nodes.
It is important to keep in mind all nodes run the same codebase, with different configurations. As such, we have split up the documentation for running different types of node into sections specific to the type of nodes.
Why run a Node?
You may decide to run a node of your own for a few reasons:
- To join a network as a validator running a validator node. Running a validator node is a public good and you are effectively securing the NEAR network and earning rewards.
- To run applications that heavily depend on RPC performance and/or availability.
- To develop and deploy contracts on a local (independent and isolated) node (sometimes called "localnet"). (†)
- To quickly extract blockchain data that can be used for chain analytics, block explorer, etc.

localnet would be the right choice if you prefer to avoid leaking information about your work during the development process since
betanet are public networks.
localnet also gives you total control over accounts, economics and other factors for more advanced use cases (ie. making changes to
