Preparing the server

Update repositories:
apt update && apt upgrade -y
install the necessary utilities:
apt install curl iptables build-essential git wget jq make gcc nano tmux htop nvme-cli pkg-config libssl-dev libleveldb-dev tar clang bsdmainutils ncdu unzip libleveldb-dev -y
install fail2ban:
sudo apt install -y fail2ban
Install Go:
ver="1.21.13" && 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

Node installation

Installing binaries:
cd $HOME mkdir -p empe-chain && cd empe-chain curl -LO https://github.com/empe-io/empe-chain-releases/raw/master/v0.2.2/emped_v0.2.2_linux_amd64.tar.gz tar -xvf emped_v0.2.2_linux_amd64.tar.gz mv emped ~/go/bin chmod u+x ~/go/bin/emped

Create validator

Check your pubkey:
emped tendermint show-validator --home /root/.empe-chain
Tx staking create validator:
cd $HOME nano /root/.empe-chain/validator.json { "pubkey": { "@type": "/cosmos.crypto.ed25519.PubKey", "key": "<your_pubkey>" }, "amount": "1000000uempe", "moniker": "BITNODES_guide", "identity": "<your_identify?", "security": "<your_email>", "details": "<your_details>", "website": "<your_website>", "commission-rate": "0.10", "commission-max-rate": "0.20", "commission-max-change-rate": "0.01", "min-self-delegation": "1" } emped --home /root/.empe-chain tx staking create-validator /root/.empe-chain/validator.json --from WalletName --chain-id empe-testnet-2 -y
(OPTIONAL) Tx staking edit validator:
emped tx staking edit-validator --new-moniker "your_moniker" --identity "Keybase_ID" --details "Your_Description" --website "Your_Website" --security-contact "Your_Email" --chain-id empe-testnet-2 --commission-rate 0.05 --from WalletName --gas 0.003 -y
