## Configuring Your Node
Next, download the correct genesis file and sync your node with the Kava mainnet. To download the genesis file:
```bash
# First, initialize kvd. Replace <name> with the public name of your node
kvd init --chain-id kava-8 <name>
# First, initialize kava. Replace <name> with the public name of your node
kava init --chain-id kava-9 <name>
# Download the genesis file
wget https://kava-genesis-files.s3.amazonaws.com/kava-8-genesis-migrated-from-block-1878508.json -O ~/.kvd/config/genesis.json

Next, adjust some configurations. To open the config file:
```bash
vim $HOME/.kvd/config/config.toml
vim $HOME/.kava/config/config.toml

Next, chose how much historical state you want to store. To open the application config file:
```bash

vim $HOME/.kava/config/app.toml
```
In this file, choose between `default`, `nothing`, and `everything`. To reduce hard drive storage, choose `everything` or `default`. To run an archival node, chose `nothing`.

### Syncing Your Node
To sync your node, you will use systemd, which manages the Kava daemon and automatically restarts it in case of failure. To use systemd, you will create a service file. Be sure to replace `<your_user>` with the user on your server:
```bash
sudo tee /etc/systemd/system/kvd.service > /dev/null <<'EOF'
sudo tee /etc/systemd/system/kavad.service > /dev/null <<'EOF'
[Unit]
Description=Kava daemon
After=network-online.target

To start syncing:
```bash
# Start the node
sudo systemctl enable kvd
sudo systemctl start kvd
sudo systemctl enable kavad
sudo systemctl start kavad
```
To check on the status of syncing:
```bash
kvcli status --output json | jq '.sync_info'
kava status --log_format json | jq '.sync_info'
```
This will give output like:

The main thing to watch is that the block height is increasing. Once you are caught up with the chain, `catching_up` will become false. At that point, you can start using your node to create a validator. If you need to sync using a snapshot, please use https://kava.quicksync.io/
To check the logs of the node:
```bash
sudo journalctl -u kvd -f
sudo journalctl -u kavad -f
```
## Creating a Validator
First, create a wallet, which will give you a private key / public key pair for your node.
```bash
# Replace <your-key-name> with a name for your key that you will remember
kvcli keys add <your-key-name>
kava keys add <your-key-name>
# To see a list of wallets on your node
kvcli keys list
kava keys list
```
**Be sure to write down the mnemonic for your wallet and store it securely. Losing your mnemonic could result in the irrecoverable loss of KAVA tokens.**
To see the options when creating a validator:
```bash
kvcli tx staking create-validator -h
kava tx staking create-validator -h
```
An example of creating a validator with 50KAVA self-delegation and 10% commission:
```bash
# Replace <key_name> with the key you created previously
kvcli tx staking create-validator \
kava tx staking create-validator \
--amount=50000000ukava \
--pubkey=$(kvd tendermint show-validator) \
--pubkey=$(kava tendermint show-validator) \
--moniker="choose moniker" \
--website="optional website for your validator"
--details="optional details for your validator"
--website="optional website for your validator" \
--details="optional details for your validator" \
--commission-rate="0.10" \
--commission-max-rate="0.20" \
--commission-max-change-rate="0.01" \
--min-self-delegation="1" \
--from=<key_name> \
--chain-id=kava-8 \
--gas=auto
--from=<your-key-name> \
--chain-id=kava-9 \
--gas=auto \
--gas-adjustment=1.4
```
To check on the status of your validator:
```bash
kvcli status --output json | jq '.validator_info'
kava status --log_format json | jq '.ValidatorInfo'
```
After you have completed this guide, your validator should be up and ready to receive delegations. Note that only the top 100 validators by weighted stake (self-delegations + other delegations) are eligible for block rewards.
