### 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/main/AutoInstall/empeiria.sh)
```

### Sync Node

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

### Run a Validator

> Öncelikle kendimize bir cüzdan açıyoruz. `wallet` yerine bir tane cüzdan ismi belirliyoruz.&#x20;

```
emped keys add wallet
```

```
emped tx staking create-validator \
--amount 1000000uempe \
--from wallet \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--pubkey $(emped tendermint show-validator) \
--moniker "Testnet" \
--identity "" \
--website "" \
--security-contact="" \
--details "CoinHunters Community" \
--chain-id empe-testnet-2 \
--gas auto --gas-adjustment 1.5 --fees 30uempe \
-y
```

> `wallet` yerine belirlediğiniz cüzdan adını yazıyoruz. `moniker` yerine Validator ismini ekliyoruz. `identity` de keybase.io adresnden yükleyeceğiniz avatar'ın ID'sini ekliyoruz. `website`, yerine siteniz var ise onu, yoksa twitter vs. eklerseniz. `Security-contact` yerine mail adresinizi, `details` yerine istediğiniz bir açıklamayı yazabilirsiniz.&#x20;
