Setting up Validator Node​

1. Install Fullnode​

Follow the instructions here to set up a full node.

2. Start Validator Node​

Put priv_validator_key.json, which contains your validator key, into config directory. The file looks like this:

{
  "address": "A3258DCBF45DCA0DF052981870F2D1441A36D145",
  "pub_key": {
    "type": "tendermint/PubKeyEd25519",
    "value": "AT/+aaL1eB0477Mud9JMm8Sh8BIvOYlPGC9KkIUmFaE="
  },
  "priv_key": {
    "type": "tendermint/PrivKeyEd25519",
    "value": "EVkqJO/jIXp3rkASXfh9YnyToYXRXhBr6g9cQVxPFnQBP/5povV4HTjvsy530kybxKHwEi85iU8YL0qQhSYVoQ=="
  }
}

Then start your node.

bnbchaind start &
note

Alternatively, if you choose a different $BNCHOME location and you are not using the suggested default ~/.bnbchaind, you may start the full node by using below script, where $BNCHOME is your selected directory.

Example: If you set /usr/local/beacon-chain as your home directory. Run the Full Node with:

bnbchaind start --home /usr/local/beacon-chain &

Post Running​

1. Monitor Node Status​

You can check the overall status by accessing the following url.

curl localhost:26657/status

2. Change Keys​

Your can stop your node, and replace priv_validator_key.json with a new one.

3. Stop Validating​

After unbonding, your node will stop validating new blocks.
