How to join Munchain network
Infrastructure
**Recommended configuration:**
- Number of CPUs: 4
- Memory: 16GB
- OS: Ubuntu 22.04 LTS
- Allow all incoming connections from TCP port 26656 and 26657
Static IP address
- The recommended configuration from AWS is the equivalent of a t2.large machine
with 300GB EBS attached storage.
Installing prerequisites
sudo apt update
sudo apt upgrade -y
sudo apt install build-essential jq -y
Install Golang:
Install latest go version https://golang.org/doc/install
wget -q -O - https://raw.githubusercontent.com/canha/golang-tools-install-script/master/goinstall.sh | bash -s -- --version 1.18
source ~/.profile
To verify that Golang installed
go version
// Should return go version go1.18 linux/amd64
Clone repository
git clone https://github.com/munblockchain/mun
cd mun
Install the executables
sudo rm -rf ~/.mun
go mod tidy
make install
clear
mkdir -p ~/.mun/upgrade_manager/upgrades
mkdir -p ~/.mun/upgrade_manager/genesis/bin
Symlink genesis binary to upgrade
cp $(which mund) ~/.mun/upgrade_manager/genesis/bin
sudo cp $(which mund-manager) /usr/bin
Initialize the validator with a moniker name (Example moniker_name: solid-moon-rock)
mund init [moniker_name] --chain-id testmun
Add a new wallet address, store seeds and buy TMUN to it. (Example wallet_name: solid-moon-rock)
mund keys add [wallet_name] --keyring-backend test
Fetch genesis.json from genesis node
curl --tlsv1 https://node1.mun.money/genesis? | jq ".result.genesis" > ~/.mun/config/genesis.json
Update seed in config.toml to make p2p connection ( Please use seed2 or seed3, since it has a connection limit)
seed1 = "[email protected]:26656" seed2 = "[email protected]:26656" seed3 = "[email protected]:26656"
nano ~/.mun/config/config.toml
seeds = "[email protected]:26656"
Replace stake to TMUN
sed -i 's/stake/utmun/g' ~/.mun/config/genesis.json
Create the service file "/etc/systemd/system/mund.service" with the following content
sudo nano /etc/systemd/system/mund.service
Paste following content(*Please make sure to use correct name of user, group and DAEMON_HOME path at the below.)

- How to get DAEMON_HOME path
cd ~/.mun
pwd
Create log files and starts running the node
make log-files
sudo systemctl enable mund
sudo systemctl start mund
Verify node is running properly
mund status
After buying TMUN, stake it to become a validator.
Tips
You should wait until the node gets fully synchronized with other nodes. You can cross check with the genesis node by visiting https://node1.mun.money/status and check the latest block height. You can also check your node status through this link http://[Your_Node_IP]:26657/status.
Or visit https://blockexplorer.mun.money
