Node Installation

There is 2 ways to install node , using Cosmovisor or Run the binary directly, you can choose whats you prefer

Cosmovisor (Recommended)

# Download and install binary
cd $HOME
rm -rf c4e-chain/
git clone https://github.com/chain4energy/c4e-chain.git
cd c4e-chain/
git checkout v1.2.1
make build


# Setup Cosmovisor Symlinks
mkdir -p $HOME/.c4e-chain/cosmovisor/genesis/bin
mv build/c4ed $HOME/.c4e-chain/cosmovisor/genesis/bin/
rm -rf build

sudo ln -s $HOME/.c4e-chain/cosmovisor/genesis $HOME/.c4e-chain/cosmovisor/current
sudo ln -s $HOME/.c4e-chain/cosmovisor/current/bin/c4ed /usr/local/bin/c4ed


# Set Configuration for your node
c4ed config chain-id perun-1
c4ed config keyring-backend file


# Init your node
# You can change "MyNode" to anything you like
c4ed init MyNode --chain-id perun-1


# Add Genesis File and Addrbook
wget https://raw.githubusercontent.com/chain4energy/c4e-chains/main/perun-1/genesis.json -O $HOME/.c4e-chain/config/genesis.json
