Althea

Chain ID
Version
Go

For Ubuntu 22.04 or later. The node listens on ports starting with your port prefix (e.g. 26657 becomes 16657), so several nodes can share a server.

  1. 01Install tools

    sudo apt update && sudo apt upgrade -y
sudo apt install -y curl git wget jq make gcc build-essential lz4 zstd tmux htop unzip

  2. 02Install Go

    cd $HOME
VER="<go-version>"
wget "https://golang.org/dl/go$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"
[ ! -f $HOME/.bash_profile ] && touch $HOME/.bash_profile
echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
source $HOME/.bash_profile
mkdir -p $HOME/go/bin
go version

  3. 03Build the binary

    cd $HOME
rm -rf althea-L1
git clone https://github.com/AltheaFoundation/althea-L1.git althea-L1
cd althea-L1
git checkout <version>
make install
althea version --long | grep -E '^(version|commit):'

  4. 04Install Cosmovisor

    go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@latest
DAEMON_HOME=$HOME/.althea DAEMON_NAME=althea cosmovisor init $HOME/go/bin/althea

  5. 05Create the service

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