### Hardware prerequisites[​](https://docs.dymension.xyz/validate/dymension/overview#hardware-prerequisites) <a href="#hardware-prerequisites" id="hardware-prerequisites"></a>

To prepare for the upcoming testnet and network upgrades the Dymension validators and full nodes should be prepared with the following minimum recommended hardware requirements:

* 8 cores
* 1TB of NVME disk storage
* 64gb of memory (RAM)
* 100mbps network bandwidth<br>

&#x20;**Preparing the server**<br>

```
sudo apt update && sudo apt upgrade -y 
sudo apt install curl lz4 tar wget clang pkg-config libssl-dev jq build-essential bsdmainutils git make ncdu gcc git jq chrony liblz4-tool -y
```

Install Go

```
cd $HOME 
ver="1.21.3" 
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz" 
sudo rm -rf /usr/local/go 
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz" 
rm "go$ver.linux-amd64.tar.gz" 
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile 
source $HOME/.bash_profile go version
```

```
cd $HOME 
git clone https://github.com/dymensionxyz/dymension.git 
cd dymension 
git checkout v3.1.0 
make install
```

Verify that the Dymension full node is installed correctly<br>

```
dymd version --long
```

**Example**:<br>

> name: dymension \
> server\_name: dymd \
> version: v3.1.0 \
> commit: b0e997d6b921666b7c4da4e121a87a2652ed0d2a

```
dymd init mynode --chain-id=dymension_1100-1 
dymd config chain-id dymension_1100-1
```

Create Wallet, to restore exexuting wallet, use the flag recover

```
dymd keys add OR dymd keys add --recover
```

Download Genesis:

```
wget https://github.com/dymensionxyz/networks/raw/main/mainnet/dymension/genesis.json -O $HOME/.dymension/config/genesis.json
```

Download Addrbook:

> ```bash
> wget -O $HOME/.celestia-app/config/addrbook.json https://mainnet-files.itrocket.net/celestia/addrbook.json
> ```

> ```
> Add seeds
> ```
>
> ```
>
> sed -i -e "s|^seeds *=.*|seeds = \"400f3d9e30b69e78a7fb891f60d76fa3c73f0ecc@dymension.rpc.kjnodes.com:14659\"|" $HOME/.dymension/config/config.toml
> ```

```
Set minimum gas price
```

> ```
> sed -i -e "s|^minimum-gas-prices *=.*|minimum-gas-prices = \"20000000000adym\"|" $HOME/.dymension/config/app.toml
> ```

> **Set pruning**

```
sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
  -e 's|^pruning-interval *=.*|pruning-interval = "19"|' \
  $HOME/.dymension/config/app.toml
```

Create systemd&#x20;

```
sudo tee /etc/systemd/system/dymd.service > /dev/null <<EOF 
[Unit] 
Description=DYMENSION\n 
After=network.target 
[Service] 
Type=simple 
User=$USER
 ExecStart=$(which dymd) start 
Restart=on-failure 
RestartSec=10 
LimitNOFILE=65535 
[Install] 
WantedBy=multi-user.target 
EOF
```

```
sudo systemctl daemon-reload 
sudo systemctl enable dymd
```

**SnapShot Mainnet updated every 5 hours**

```
cd $HOME apt install lz4 
sudo systemctl stop dymd 
cp $HOME/.dymension/data/priv_validator_state.json $HOME/.dymension/priv_validator_state.json.backup 
rm -rf $HOME/.dymension/data 
curl -o - -L https://dymension-m.snapshot.stavr.tech/dymension-snap.tar.lz4 | lz4 -c -d - | tar -x -C $HOME/.dymension --strip-components 2 
mv $HOME/.dymension/priv_validator_state.json.backup $HOME/.dymension/data/priv_validator_state.json 
wget -O $HOME/.dymension/config/addrbook.json "https://raw.githubusercontent.com/111STAVR111/props/main/Dymension/addrbook.json" 
sudo systemctl restart dymd && journalctl -u dymd -f -o cat
```

Check Sync, If catching up = false maybe create validator:

```
dymd status
dymd status 2>&1 | jq .SyncInfo
```

```
dymd tx staking create-validator
--commission-rate 0.1
--commission-max-rate 0.2
--commission-max-change-rate 0.2
--min-self-delegation "1000000"
--amount 1000000000000000000adym
--pubkey $(dymd tendermint show-validator)
--from
--gas 350000
--fees 7000000000000000adym
--moniker="Your Validator"
--chain-id="dymension_1100-1"
--identity=""
--website=""
--details="" -y
```
