Pan chain has ended to make way for our mainnet.
This repo has been archived.
Pan is the first MOONBYS.com public blockchain testnet.
It is a blockchain built with Cosmos SDK, Tendermint and created with Starport.
In this guide you will find how to install the latest binary
These are the minimal hardware configs required for running a validator/sentry node:
- 4GB RAM
- 2vCPUs (4vCPUs is recommended)
- 100GB SSD Disk space per year (NVMe disks are recommended)
- 100 Mbit/s bandwidth (Lower bandwidth may also work in devnet)
Please avoid cheap VPS providers as a mainnet validator. You could use these as a cheap backup or for testing. (We do not recommend these. Use them at your own risk) We advise to use a shared dedicated server or a high-end NVMe VPS.
- Make sure that your system is up to date. You should also install a utility named
jqto read and navigate in JSON files and outputs.
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get install -y build-essential curl wget jq
- Increase the default open files limit. If you don't raise this value, nodes will crash when the network grows large enough.
sudo su -c "echo 'fs.file-max = 65536' >> /etc/sysctl.conf"
sudo sysctl -p
- Install GoLang You can find the official instructions at: https://golang.org/doc/install
- Remove any old versions that you might have installed in your system
apt purge golang-go
apt autoremove
rm -rf /usr/local/go
- Download the software
wget -c https://golang.org/dl/go1.17.1.linux-amd64.tar.gz
tar xvf go1.17.1.linux-amd64.tar.gz -C /usr/local
- Update environment variables to include Go
cat >> ~/.profile << 'EOF'
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
EOF
source ~/.profile
- Verify that Go was installed correctly:
go version
You should see go version go1.17.7 linux/amd64
- Check the latest version at https://github.com/MOONBYS/pan/releases (If needed, change the command below to the latest version)
cd $HOME
wget -nc https://github.com/moonbys/pan/releases/download/v0.2.1/moonbys
chmod +x moonbys
sudo mv moonbys /usr/local/bin/
source ~/.profile
- Confirm that you downloaded the correct version
moonbys version
You should now have the moonbys binary in your /usr/local/bin/ directory
moonbys
Create a wallet
moonbys keys add YOURWALLETNAME --keyring-backend os
This command will generate a new wallet, it will give you an address, a pubkey and a mnemonic phrase.
You will also be asked to create a password.
Make sure that you save your mnemonic phrase in a secure place, never share it with anyone and don't forget your keyring password.
To get some test tokens, scroll down and join the MOONBYS Discord server or the MOONBYS Telegram chat. Ask for some test tokens there.
moonbys init YOURNODE
You can choose any name that you want for your node.
Your node's name will be public in the network.
Delete default genesis file and download the Pan Chain genesis file into ~/.pan/config/
cd .pan/config
sudo rm -rf genesis.json
wget https://moonbys.com/pan-chain/genesis.json
Add the published node ID and IP into the configuration file:
nano .pan/config/config.toml
Find the following line and add the node-id and IP
# Comma separated list of nodes to keep persistent connections to
persistent_peers = "3b4085e151b09d360de37c59e0da795df9b52b61@142.132.190.68:26656"
Adjust fees
nano .pan/config/app.toml
Find the following line and adjust fees (change "0stake" to "0.001upan")
# The minimum gas prices a validator is willing to accept for processing a
# transaction. A transaction's fees must meet the minimum of any denomination
# specified in this config (e.g. 0.25token1;0.0001token2).
minimum-gas-prices = "0.001upan"
moonbys start
Make sure that you have stopped the chain with CTRL+C. You can always restart your node with moonbys start. Setting up a systemd will make things simpler, it will keep your node running and it will make it auto-restart.
cd $HOME
echo "[Unit]
Description=Moonbys Node
After=network-online.target
[Service]
User=${USER}
ExecStart=$(which moonbys) start
Restart=always
RestartSec=3
LimitNOFILE=4096
[Install]
WantedBy=multi-user.target
" >moonbys.service
Enable and activate the MOONBYS service
sudo mv moonbys.service /lib/systemd/system/
sudo systemctl enable moonbys.service && sudo systemctl start moonbys.service
Check the logs and confirm that the service is working
sudo journalctl -u moonbys -f
Before setting up your validator node, make sure that you've already gone through the steps above and that your node is caught up with the chain.
You can become a validator with this simple command:
moonbys tx staking create-validator --amount="atleast1000000upan" --pubkey="$(moonbys tendermint show-validator)" --moniker="YourMoniker" --chain-id="pan-chain" --commission-rate="0.10" --commission-max-rate="0.20" --commission-max-change-rate="0.01" --min-self-delegation="1" --fees="5000upan" --from="YourKeyName" --keyring-backend="os"
You can add the following flags to the previous command:
--website="https://your-validator.com" \
--identity=A 16 digit code-key from keybase.io \
--details="Your validator's description and details!" \
You can always edit your validator with:
moonbys tx staking edit-validator
