```

#### enable and start service

```
sudo systemctl daemon-reload
sudo systemctl enable junctiond
sudo systemctl restart junctiond && sudo journalctl -u junctiond -fo cat
```

#### Snapshot

#### Stop the service and reset the data <a href="#stop-the-service-and-reset-the-data" id="stop-the-service-and-reset-the-data"></a>

```
sudo systemctl stop junctiond
cp $HOME/.junctiond/data/priv_validator_state.json $HOME/.junction/priv_validator_state.json.backup
rm -rf $HOME/.junctiond/data
```

#### Download latest snapshot <a href="#download-latest-snapshot" id="download-latest-snapshot"></a>

```
curl -L https://snapshots.coinhunterstr.com/data.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.junctiond
mv $HOME/.junctiond/priv_validator_state.json.backup $HOME/.junctiond/data/priv_validator_state.json
```

#### Restart the service and check the log <a href="#restart-the-service-and-check-the-log" id="restart-the-service-and-check-the-log"></a>

```
sudo systemctl start junctiond && sudo journalctl -u junctiond -f --no-hostname -o cat
```

### Automatic Installation <a href="#auto-installation" id="auto-installation"></a>

> Moniker yerine Validator isminizi yazıp enter basın.

```
bash <(wget -qO- https://raw.githubusercontent.com/CoinHuntersTR/props/refs/heads/main/AutoInstall/airchains_v.sh)
```

### Sync Node

> Node ağ ile eşleşmiş olması gerekiyor. Bunun için `junctiond status 2>&1 | jq` komutunu çalıştırdığınızda `false` çıktısı vermesi gerekir. `True` çıktı alırsanız aşağıdaki adımlara devam etmeyin.

### Run a Validator

> İlk önce Pubkeyimizi alıyoruz.

```
junctiond comet show-validator
```

`{"@type":"/cosmos.crypto.ed25519.PubKey","key":"0LuMdRNJpWGiH+b+................"}` buna benzer bir çıktı alacaksınız.

```
cd $HOME
```

> Sonrasında validator json dosyası açıyoruz.

```
nano /root/validator.json
```

> Aşağıdaki dosyayı kendinize göre düzenlemeyi unutmayın. Validator ismi, site linkleri vs.

```
{
	"pubkey": <validator-pub-key>,
	"amount": "9900000amf",
	"moniker": "<validator-name>",
	"identity": "optional identity signature (ex. UPort or Keybase)",
	"website": "validator's (optional) website",
	"security": "validator's (optional) security contact email",
	"details": "validator's (optional) details",
	"commission-rate": "0.1",
	"commission-max-rate": "0.2",
	"commission-max-change-rate": "0.01",
	"min-self-delegation": "1"
}
```

> terminale yapıştırdıktan sonra, CTRL X Y enter ile çıkıyoruz.
>
> Şimdi tekrardan node restart atalım

```
sudo systemctl restart junctiond
```

> Şimdi aşağıdaki komutu çalıştırıyoruz. `wallet` yerine kendi cüzdan isminizi yazmayı unutmayın. Terminale cüzdan kurmak için `Useful Commands` bölümüne bakabilirsiniz.

```
junctiond tx staking create-validator $HOME/validator.json --from wallet --chain-id varanasi-1 --fees 0uamf
```
