Setting Variables

The areas you need to change are written below.

$OG_NODENAME your validator name
$OG_WALLET your wallet name
If another node is using the port, you can change it below. You must enter a different value where it says 11, again as two digits.

echo "export OG_NODENAME=$OG_NODENAME"  >> $HOME/.bash_profile
echo "export OG_WALLET=$OG_WALLET" >> $HOME/.bash_profile
echo "export OG_PORT=11" >> $HOME/.bash_profile
echo "export OG_CHAIN_ID=zgtendermint_16600-2" >> $HOME/.bash_profile
source $HOME/.bash_profile

Sample

Let's assume that your Node (OG_NODENAME) and Wallet (OG_WALLET) name is Anatolian-Guide and the port you will use (OG_PORT) will be 16656. The code will be arranged as shown below.

echo "export OG_NODENAME=Anatolian-Guide"  >> $HOME/.bash_profile
echo "export OG_WALLET=Anatolian-Guide" >> $HOME/.bash_profile
echo "export OG_PORT=16" >> $HOME/.bash_profile
echo "export OG_CHAIN_ID=zgtendermint_16600-2" >> $HOME/.bash_profile
source $HOME/.bash_profile

Installing 0G

cd $HOME
rm -rf 0g-chain
git clone https://github.com/0glabs/0g-chain.git
cd 0g-chain
git checkout v0.3.1
git submodule update --init
make install

warning

AFTER THIS STAGE, WE EXPECT OUR NODE TO SYNC.

Checking Synchronization

Unless we get a false output, we do not move on to the next step, namely creating a validator.

0gchaind status 2>&1 | jq .sync_info

0gchaind status 2>&1 | jq -r .sync_info.catching_up

Wallet

Creating a New Wallet

We do not change the $OG_WALLET section, we named our wallet with variables at the beginning of the installation.

0gchaind keys add $OG_WALLET --eth

Importing an Existing Wallet

0gchaind keys add $OG_WALLET --eth --recover

Learning Your EVM Address

echo "0x$(0gchaind debug addr $(0gchaind keys show $OG_WALLET -a) | grep hex | awk '{print $3}')"

Faucet

And then request tokens from the faucet to your address above.

Add Network to Wallet

Field	Details
Network name	0g Newton Testnet
New RPC URL	https://rpc-testnet.0g.ai/
Chain ID	9000
Currency symbol:	A0GI

Wallet and Valoper Info

Here we add our wallet and valve information to the variable.

OG_WALLET_ADDRESS=$(0gchaind keys show $OG_WALLET -a)
OG_VALOPER_ADDRESS=$(0gchaind keys show $OG_WALLET --bech val -a)

echo 'export OG_WALLET_ADDRESS='${OG_WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export OG_VALOPER_ADDRESS='${OG_VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile

Checking Wallet Balance

0gchaind query bank balances $OG_WALLET_ADDRESS

warning

If the synchronization is completed, we proceed to the following step.

Creating Validator

You do not need to make any changes to the following command other than the places specified below;

identity where it says XXXX1111XXXX1111 you write your identification number given to you as a member of the keybase site.
details You can write information about yourself where it says Always forward with the Anatolian Team 🐆.
website where it says https://anatolianteam.com, if you have a website or twitter etc. You can write your address.
security-contact Your email address.

Completely Deleting the Node

systemctl daemon-reload && \
cd $HOME && \
rm -rf .0gchain 0g-chain && \
