## Running a bootnode

Bootnodes are super-lightweight nodes that are not behind a NAT and are running just discovery protocol. When you start up a node it should log your enode, which is a public identifier that others can use to connect to your node.

First the bootnode requires a key, which can be created with the following command, which will save a key to boot.key:

```
bootnode -genkey boot.key
```

This key can then be used to generate a bootnode as follows:

```
bootnode -nodekey boot.key -addr :30311 -network bsc
```

The choice of port passed to -addr is arbitrary.
The bootnode command returns the following logs to the terminal, confirming that it is running:

Note: you're using cmd/bootnode, a developer tool.
We recommend using a regular node as bootstrap node for production deployments.
