Installation

If you want to setup Empower fullnode manually follow the steps below

Update and upgrade

sudo apt update && sudo apt upgrade -y

Install GO

if ! [ -x "$(command -v go)" ]; then
  ver="1.20.1"
  cd $HOME
  wget "https://golang.org/dl/go$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" >> ~/.bash_profile
  source ~/.bash_profile
fi

Install node

cd $HOME
rm -rf empowerchain
git clone https://github.com/EmpowerPlastic/empowerchain
cd empowerchain/chain
git checkout v1.0.0-rc2
make install

Setting up vars

You should replace values in <> <YOUR_MONIKER> Here you should put name of your moniker (validator) that will be visible in explorer <YOUR_WALLET> Here you shoud put the name of your wallet

echo "export EMPOWER_WALLET="<YOUR_WALLET_NAME>"" >> $HOME/.bash_profile
echo "export EMPOWER_NODENAME="<YOUR_MONIKER>"" >> $HOME/.bash_profile
echo "export EMPOWER_CHAIN_ID="circulus-1"" >> $HOME/.bash_profile
source $HOME/.bash_profile

Configure your node

empowerd config chain-id ${EMPOWER_CHAIN_ID}

Initialize your node

empowerd init ${EMPOWER_NODENAME} --chain-id ${EMPOWER_CHAIN_ID}

Download genesis

wget "$HOME/.empowerchain/config/genesis.json" "http://snapshots.l0vd.com/empower/genesis.json" 

(OPTIONAL) Set custom ports

If you want to use non-default ports

EMPOWER_PORT=<SET_CUSTOM_PORT> #Example: EMPOWER_PORT=56 (numbers from 1 to 64)

sed -i.bak -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:$"EMPOWER_PORT"658\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:$"EMPOWER_PORT"657\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:$"EMPOWER_PORT"060\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:$"EMPOWER_PORT"656\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":$"EMPOWER_PORT"660\"%" $HOME/.empowerchain/config/config.toml
sed -i.bak -e "s%^address = \"tcp://0.0.0.0:1317\"%address = \"tcp://0.0.0.0:$"EMPOWER_PORT"317\"%; s%^address = \":8080\"%address = \":$"EMPOWER_PORT"080\"%; s%^address = \"0.0.0.0:9090\"%address = \"0.0.0.0:$"EMPOWER_PORT"090\"%; s%^address = \"0.0.0.0:9091\"%address = \"0.0.0.0:$"EMPOWER_PORT"091\"%; s%^address = \"0.0.0.0:8545\"%address = \"0.0.0.0:$"EMPOWER_PORT"545\"%; s%^ws-address = \"0.0.0.0:8546\"%ws-address = \"0.0.0.0:$"EMPOWER_PORT"546\"%" $HOME/.empowerchain/config/app.toml

Set seeds and peers

PEERS="[e-mail]:24656"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.empowerchain/config/config.toml

Config pruning

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="50"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.empowerchain/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.empowerchain/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.empowerchain/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.empowerchain/config/app.toml

Set minimum gas price and null indexer

sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0umpwr\"/" $HOME/.empowerchain/config/app.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.empowerchain/config/config.toml

Create Service

sudo tee /etc/systemd/system/empowerd.service > /dev/null <<EOF

After=network-online.target

Reset blockchain info and restart your node

sudo systemctl daemon-reload
sudo systemctl enable empowerd
empowerd tendermint unsafe-reset-all --home $HOME/.empowerchain --keep-addr-book
sudo systemctl restart empowerd && sudo journalctl -u empowerd -f -o cat

(OPTIONAL) Use State Sync

State Sync

Starting a validator

1. Add a new key

empowerd keys add ${EMPOWER_WALLET}

(OR)

1. Recover your key

empowerd keys add ${EMPOWER_WALLET} --recover

2. Create validator

Wait until the node is synchronized.

empowerd tx staking create-validator \
