# Validator private key

In order to keep your node's ID persistent between restarts, run

`odin-testnet-public-tools/node/export.sh`

This will save your `priv_validator_key.json` private key and `node_key.json` node ID key to files under `odin-testnet-public-tools/node/config/`. Copy these to somewhere safe.
