## **1. Minimum hardware requirement**

4 Cores, 16G Ram,  160G SSD, <mark style="color:red;">**Ubuntu 22.04**</mark>

## 2. Auto Install

**Use snapshot:**

```
sudo apt install curl -y && wget https://nodesync.top/alignedlayer_auto && chmod +x alignedlayer_auto && ./alignedlayer_auto
```

### 2.1 Wallet

Add New Wallet Key - <mark style="color:red;">**Save seed**</mark>

```
alignedlayerd keys add wallet
```

Recover existing key

```
alignedlayerd keys add wallet --recover
```

List All Keys

```
alignedlayerd keys list
```

### 2.2 Query Wallet Balance

```
alignedlayerd q bank balances $(alignedlayerd keys show wallet -a)
```

### 2.3 Check sync status

<mark style="color:red;">**False is synced**</mark>

```
alignedlayerd status 2>&1 | jq .sync_info
```

### 2.4 Create Validator

**Obtain your validator public key by running the following command:**

```
alignedlayerd comet show-validator
```

**The output will be similar to this (with a different key):**

{"@type":"/cosmos.crypto.ed25519.PubKey","key":"lR1d7YBVK5jYijOfWVKRFoWCsS4dg3kagT7LB9GnG8I="}

**Then, create a file named** `validator.json` **with the following content:**

```
nano $HOME/validator.json
```

Change your info, from "pubkey" to "details"  and Save them

```
{    
    "pubkey": {"@type":"/cosmos.crypto.ed25519.PubKey","key":"lR1d7YBVK5jYijOfWVKRFoWCsS4dg3kagT7LB9GnG8I="},
    "amount": "1000000stake",
    "moniker": "your-node-moniker",
    "identity": "eqlab testnet validator",
    "website": "optional website for your validator",
    "security": "optional security contact for your validator",
    "details": "optional details for your validator",
    "commission-rate": "0.1",
    "commission-max-rate": "0.2",
    "commission-max-change-rate": "0.01",
    "min-self-delegation": "1"
}
```

**Finally, we're ready to submit the transaction to create the validator:**

```
alignedlayerd tx staking create-validator $HOME/validator.json \
--from wallet --chain-id alignedlayer \
--fees 50stake
```

### 2.5 Delegate Token to your own validator

```
alignedlayerd tx staking delegate $(alignedlayerd keys show wallet --bech val -a)  1000000stake \
--from wallet --chain-id alignedlayer \
--fees 50stake
```

### 2.6 Withdraw rewards and commission from your validator

```
alignedlayerd tx distribution withdraw-rewards $(alignedlayerd keys show wallet --bech val -a) \
--from wallet --chain-id alignedlayer \
--fees 50stake
```

### 2.7 Unjail validator

<pre><code><strong>alignedlayerd tx slashing unjail --from wallet --chain-id alignedlayer --fees=50stake -y
</strong></code></pre>

```
port=16
echo "export $port" >> $HOME/.bash_profile
alignedlayerd config set config rpc.laddr "tcp://0.0.0.0:${port}657" --skip-validate
sed -i.bak -e "s%:1317%:${port}317%g; s%:8080%:${port}080%g; s%:9090%:${port}090%g; s%:9091%:${port}091%g; s%:8545%:${port}545%g; s%:8546%:${port}546%g; s%:6065%:${port}065%g" $HOME/.alignedlayer/config/app.toml
