Installation

Updating the System​

apt update && apt upgrade -y

Installing the Necessary Libraries​

apt install make clang pkg-config libssl-dev libclang-dev build-essential git curl ntp jq llvm tmux htop screen gcc lz4 -y < "/dev/null"

Installing Go​

ver="1.21.5"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
rm -rf /usr/local/go
tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm -rf "go$ver.linux-amd64.tar.gz"
echo 'export GOROOT=/usr/local/go' >> $HOME/.bash_profile
echo 'export GOPATH=$HOME/go' >> $HOME/.bash_profile
echo 'export GO111MODULE=on' >> $HOME/.bash_profile
echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

Setting Variables​

The areas you need to change are written below.

  • $BBN_NODENAME your validator name
  • $BBN_WALLET your wallet name
  • If another node is using the port, you can change it below. You must enter a different value where it says 11, again as two digits.
echo "export BBN_NODENAME=$BBN_NODENAME"  >> $HOME/.bash_profile
echo "export BBN_WALLET=$BBN_WALLET" >> $HOME/.bash_profile
echo "export BBN_PORT=11" >> $HOME/.bash_profile
echo "export BBN_CHAIN_ID=bbn-test-3" >> $HOME/.bash_profile
source $HOME/.bash_profile

Sample​

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

echo "export BBN_NODENAME=Anatolian-Guide"  >> $HOME/.bash_profile
echo "export BBN_WALLET=Anatolian-Guide" >> $HOME/.bash_profile
echo "export BBN_PORT=16" >> $HOME/.bash_profile
echo "export BBN_CHAIN_ID=bbn-test-2" >> $HOME/.bash_profile
source $HOME/.bash_profile

Installing Babylon​

cd $HOME
git clone https://github.com/babylonchain/babylon.git babylon
cd babylon
git checkout v0.8.3
make install
babylond version

The version output will be 0.8.3.

Configuring and Launching the Node​

We copy and paste the codes below without making any changes.

Enabling the Service​

systemctl daemon-reload
systemctl enable babylond

Checking the Logs​

journalctl -u babylond -f -o cat
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.

babylond status 2>&1 | jq .SyncInfo

Wallet​

Creating a New Wallet​

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

babylond keys add $BBN_WALLET

Importing an Existing Wallet​

babylond keys add $BBN_WALLET --recover

Wallet and Valoper Info​

Here, wallet and valoper information are added to the variable.

BBN_WALLET_ADDRESS=$(babylond keys show $BBN_WALLET -a)
BBN_VALOPER_ADDRESS=$(babylond keys show $BBN_WALLET --bech val -a)
echo 'export BBN_WALLET_ADDRESS='${BBN_WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export BBN_VALOPER_ADDRESS='${BBN_VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile

Checking Wallet Balance​

babylond query bank balances $BBN_WALLET_ADDRESS
warning

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

Creating BLS Key and Restarting​

# app.toml ve config.toml Düzenleme
sed -i -e "s|^key-name *=.*|key-name = \"$BBN_WALLET\"|" $HOME/.babylond/config/app.toml
sed -i -e "s|^timeout_commit *=.*|timeout_commit = \"10s\"|" $HOME/.babylond/config/config.toml
babylond create-bls-key $(babylond keys show $BBN_WALLET -a)
sudo systemctl restart babylond

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.
babylond tx checkpointing create-validator \

Completely Deleting the Node​

systemctl stop babylond && \
systemctl disable babylond && \
rm /etc/systemd/system/babylond.service && \
systemctl daemon-reload && \
cd $HOME && \
rm .babylond babylon -rf && \
