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="1.21.6"
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.

  • $CFI_NODENAME your validator name
  • $CFI_WALLET your wallet name
  • If another node is using the port, you can change it below. You must enter a different value where it says 11, again as two digits.
echo "export CFI_NODENAME=$CFI_NODENAME"  >> $HOME/.bash_profile
echo "export CFI_WALLET=$CFI_WALLET" >> $HOME/.bash_profile
echo "export CFI_PORT=11" >> $HOME/.bash_profile
echo "export CFI_CHAIN_ID=crossfi-evm-testnet-1" >> $HOME/.bash_profile
source $HOME/.bash_profile

Sample​

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

echo "export CFI_NODENAME=Anatolian-Guide"  >> $HOME/.bash_profile
echo "export CFI_WALLET=Anatolian-Guide" >> $HOME/.bash_profile
echo "export CFI_PORT=16" >> $HOME/.bash_profile
echo "export CFI_CHAIN_ID=crossfi-evm-testnet-1" >> $HOME/.bash_profile
source $HOME/.bash_profile

Installing CrossFi​

cd $HOME
mkdir -p $HOME/go/bin
wget https://github.com/crossfichain/crossfi-node/releases/download/v0.3.0-prebuild9/crossfi-node_0.3.0-prebuild9_linux_amd64.tar.gz
tar -xvf crossfi-node_0.3.0-prebuild9_linux_amd64.tar.gz
chmod +x $HOME/bin/crossfid
mv $HOME/bin/crossfid $HOME/go/bin
rm crossfi-node_0.3.0-prebuild9_linux_amd64.tar.gz
crossfid version

The version output will be 0.3.0-prebuild9.

Configuring and Launching the Node​

Enabling and Starting the Service​

systemctl daemon-reload
systemctl enable crossfid
systemctl start crossfid

Checking the Logs​

journalctl -u crossfid -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.

crossfid status 2>&1 | jq .SyncInfo

Wallet​

Creating a New Wallet​

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

crossfid keys add $CFI_WALLET

Importing an Existing Wallet​

crossfid keys add $CFI_WALLET --recover

Wallet and Valoper Info​

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

CFI_WALLET_ADDRESS=$(crossfid keys show $CFI_WALLET -a)
CFI_VALOPER_ADDRESS=$(crossfid keys show $CFI_WALLET --bech val -a)
echo 'export CFI_WALLET_ADDRESS='${CFI_WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export CFI_VALOPER_ADDRESS='${CFI_VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile

Checking Wallet Balance​

crossfid query bank balances $CFI_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.
