TAC Node Installation Guide

Chain ID: tacchain_239-1 | Current Node Version: v1.0.1

Install Go and Cosmovisor

Feel free to skip this step if you already have Go and Cosmovisor.

Install Go

We will use Go v1.23.4 as example here. The code below also cleanly removes any previous Go installation.

sudo rm -rvf /usr/local/go/
wget https://golang.org/dl/go1.23.4.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.23.4.linux-amd64.tar.gz
rm go1.23.4.linux-amd64.tar.gz

Configure Go

Unless you want to configure in a non-standard way, then set these in the ~/.profile file.

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin

Install Cosmovisor

We will use Cosmovisor v1.6.0 as example here.

go install github.com/cosmos/cosmos-sdk/cosmovisor/cmd/cosmovisor@v1.6.0

Install Node

Install the current version of node binary.

cd $HOME && \
git clone https://github.com/TacBuild/tacchain $HOME/tacchain && \
cd $HOME/tacchain && \
git checkout v1.0.1 && \
make install

Configure Node

Initialize Node

Please replace YOUR_MONIKER with your own moniker.

tacchaind init YOUR_MONIKER --chain-id tacchain_239-1

Download Genesis

The genesis file link below is Polkachu's mirror download. The best practice is to find the official genesis download link.

wget -O genesis.json https://tac-mainnet-services.luckystar.asia/tac/genesis.json --inet4-only
mv genesis.json $HOME/.tacchaind/config

Download addrbook

You can use addrbook or persistent_peers.

curl -Ls https://tac-mainnet-services.luckystar.asia/tac/addrbook.json > $HOME/.tacchaind/config/addrbook.json 

Launch Node

Configure Cosmovisor Folder

Create Cosmovisor folders and load the node binary.

Create Cosmovisor Folders

mkdir -p $HOME/.tacchaind/cosmovisor/genesis/bin
mkdir -p $HOME/.tacchaind/cosmovisor/upgrades

Load Node Binary into Cosmovisor Folder

cp $HOME/go/bin/tacchaind $HOME/.tacchaind/cosmovisor/genesis/bin

Create Service File

Create a tacchaind.service file in the /etc/systemd/system folder with the following code snippet. Make sure to replace USER with your Linux user name. You need sudo privilege to do this step.

sudo nano /etc/systemd/system/tacchaind.service
