Installation

C4E

Network name: C4E | Chain ID: perun-1 | Latest version: v1.3.1 | Custom Port: 266

Setup validator name

Replace YOUR_MONIKER_GOES_HERE with your validator name

MONIKER="YOUR_MONIKER_GOES_HERE"

Install dependencies

Update system and install build tools

sudo apt -q update
sudo apt -qy install curl git jq zst build-essential
sudo apt -qy upgrade

Install Go

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.19.8.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
eval $(echo 'export PATH=$PATH:/usr/local/go/bin' | sudo tee /etc/profile.d/golang.sh)
eval $(echo 'export PATH=$PATH:$HOME/go/bin' | tee -a $HOME/.profile)

Download and build binaries

# Clone project repository
cd $HOME
rm -rf chain4energy
git clone https://github.com/chain4energy/c4e-chain chain4energy
cd chain4energy
git checkout v1.3.1

# Build binaries
make install

# Prepare binaries for Cosmovisor
mkdir -p $HOME/.c4e-chain/cosmovisor/genesis/bin
mv ~/go/bin/c4ed $HOME/.c4e-chain/cosmovisor/genesis/bin/
rm -rf build
