# Installing a full node with statesync method

# Background

This guide focuses on installing a node with the statesync and cosmovisor method. The guide is very useful in case the purpose is to install a validator node: if you do not have special requirements for querying the chain about states or past transactions with your node, precisely as in the case of a validator node, then this procedure is the recommended one.

After you've setup your hardware following the hardware requirements you are now ready to become a Commercio.network full node.


Make sure you have read the hardware requirements before starting

# 1. Installing the software requirements

Choose the name of your node. In the guide you will need to replace the variable <your-moniker> with the name you choose In order to update the OS so that you can work properly, execute the following commands:

apt update && apt upgrade -y
apt install -y git gcc make unzip jq
snap install --classic go

export NODENAME="<your-moniker>"

echo 'export GOPATH="$HOME/go"' >> ~/.profile
echo 'export PATH="$GOPATH/bin:$PATH"' >> ~/.profile
echo 'export PATH="$PATH:/snap/bin"' >> ~/.profile
echo "export NODENAME=\"$NODENAME\"" >> ~/.profile

source ~/.profile

# 2. Chain selection

Before installing the node, please select which chain you would like to connect to

  • Mainnet: commercio-3
  • Testnet: commercio-testnet11k
rm -rf commercio-chains
mkdir commercio-chains && cd commercio-chains
git clone https://github.com/commercionetwork/chains.git .

# 3. Install binaries and setup configuration

Compile binaries

pkill commercionetworkd
git init . 
git remote add origin https://github.com/commercionetwork/commercionetwork.git
git pull
git checkout tags/$(cat .data | grep -oP 'Release\s+\K\S+')
go mod verify
make install

Test if you have the correct binaries version. Get version from chain data

cat .data | grep -oP 'Release\s+\K\S+'

Compare the result with the output of command

commercionetworkd version

Setup the validator node name. We will use the same name for node as well as the wallet key:

export CHAINID=commercio-$(cat .data | grep -oP 'Name\s+\K\S+')
cat <<EOF >> ~/.profile

Init the .commercionetwork folder with the basic configuration

commercionetworkd unsafe-reset-all --home ~/.commercionetwork
# If you get a error because .commercionetwork folder is not present don't worry 

commercionetworkd init $NODENAME --home ~/.commercionetwork
# If you get a error because .commercionetwork folder is present don't worry 

Change the persistent peers inside config.toml file

sed -e "s|persistent_peers = \".*\"|persistent_peers = \"$(cat .data | grep -oP 'Persistent peers\s+\K\S+')\"|g" ~/.commercionetwork/config/config.toml > ~/.commercionetwork/config/config.toml.tmp
mv ~/.commercionetwork/config/config.toml.tmp  ~/.commercionetwork/config/config.toml

Change the seeds inside the config.toml file

sed -e "s|seeds = \".*\"|seeds = \"$(cat .data | grep -oP 'Seeds\s+\K\S+')\"|g" ~/.commercionetwork/config/config.toml > ~/.commercionetwork/config/config.toml.tmp
mv ~/.commercionetwork/config/config.toml.tmp  ~/.commercionetwork/config/config.toml

Change external_address value to contact your node using public ip of your node:

PUB_IP=`curl -s -4 icanhazip.com`
sed -e "s|external_address = \".*\"|external_address = \"$PUB_IP:26656\"|g" ~/.commercionetwork/config/config.toml > ~/.commercionetwork/config/config.toml.tmp
mv ~/.commercionetwork/config/config.toml.tmp  ~/.commercionetwork/config/config.toml


At this point there may be some differences if you are using KMS with HSM.

If you are using a kms you have to configure the node so that it can accept the connection from the sign provider.
Usually the connection is within a private lan network, or via vpn. Assuming that the validator node has an internal ip such as the configuration to set up will be

priv_validator_laddr = "tcp://"

Edit ~/.commercionetwork/config/config.toml, search priv_validator_laddr, and modify the configuration.

WARN: the configuration of KMS must already be done.

# 4. Set the statesync configuration

Under the state sync section in $HOME/.commercionetwork/config/config.toml you find multiple settings that need to be configured in order for your node to use state sync. You need get information from the chain about trusted block using

Select open rpc services of chains

  • Testnet:
    • rpc-testnet.commercio.network, rpc2-testnet.commercio.network
  • Mainnet:
    • https://rpc-mainnet.commercio.network, https://rpc2-mainnet.commercio.network


You can get informations about rpc services at chain data (opens new window) repository


CURR_HEIGHT=$(curl -s "http://$TRUST_RPC1/block" | jq -r '.result.block.header.height')
TRUST_HASH=$(curl -s "http://$TRUST_RPC1/block?height=$TRUST_HEIGHT" | jq -r '.result.block_id.hash')
printf "\n\nenable = true\nrpc_servers = \"$TRUST_RPC1,$TRUST_RPC2\"\ntrust_height = $TRUST_HEIGHT\ntrust_hash = \"$TRUST_HASH\"\n\n"


CURR_HEIGHT=$(curl -s "http://$TRUST_RPC1/block" | jq -r '.result.block.header.height')
TRUST_HASH=$(curl -s "http://$TRUST_RPC1/block?height=$TRUST_HEIGHT" | jq -r '.result.block_id.hash')
printf "\n\nenable = true\nrpc_servers = \"$TRUST_RPC1,$TRUST_RPC2\"\ntrust_height = $TRUST_HEIGHT\ntrust_hash = \"$TRUST_HASH\"\n\n"

The command should return somthing like the following:

enable = true
rpc_servers = "rpc-mainnet.commercio.network:80,rpc2-mainnet.commercio.network:80"
trust_height = 6240000
trust_hash = "FCA27CBCAC3EECAEEBC3FFBB5B5433A421EF4EA873EB2A573719B0AA5093EF4C"

Edit $HOME/.commercionetwork/config/config.toml with these settings accordingly:


enable = true
rpc_servers = "rpc-mainnet.commercio.network:80,rpc2-mainnet.commercio.network:80"
trust_height = 6240000
trust_hash = "FCA27CBCAC3EECAEEBC3FFBB5B5433A421EF4EA873EB2A573719B0AA5093EF4C"

# 5. Install and config cosmovisor

# What is cosmovisor?

cosmovisor is a small process manager for Cosmos SDK application binaries that monitors the governance module for incoming chain upgrade proposals. If it sees a proposal that gets approved, cosmovisor can automatically download the new binary, stop the current binary, switch from the old binary to the new one, and finally restart the node with the new binary.
As in all other explanations, it is assumed that you are acting as root. Change the parameters and variables depending on your installation environment

# Installation

Download and compile cosmovisor:

cd $HOME
git clone https://github.com/cosmos/cosmos-sdk.git
cd cosmos-sdk
git checkout cosmovisor/v1.3.0
cd cosmovisor
make cosmovisor
cp cosmovisor $HOME/go/bin

Make cosmovisor folder structure:

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

Copy commercionetwork to cosmovisor folder

cp $HOME/go/bin/commercionetworkd $HOME/.commercionetwork/cosmovisor/genesis/bin

After installation your .commercionetwork folder should be structured like below

├── config
│   └── app.toml
│   └── config.toml
│   └── genesis.json
│   └── node_key.json
│   └── priv_validator_key.json
├── data
│   └── priv_validator_state.json
└── cosmovisor
    └── current -> /path/to/the/current/version/of/commercionetworkd
    └── genesis
    │   └── bin
    │      └── commercionetworkd
    └── upgrades
        └── <name>
           └── bin
               └── commercionetworkd

Configure the service:

tee /etc/systemd/system/commercionetworkd.service > /dev/null <<EOF  
Description=Commercio Network Node




ExecStart=/root/go/bin/cosmovisor run start --home="/root/.commercionetwork" 


Set env of cosmovisor for you convenience

echo 'export DAEMON_NAME=commercionetworkd' >> ~/.profile
echo 'export DAEMON_HOME=/root/.commercionetwork' >> ~/.profile
echo 'export DAEMON_RESTART_AFTER_UPGRADE=true' >> ~/.profile
echo 'export DAEMON_ALLOW_DOWNLOAD_BINARIES=false' >> ~/.profile
echo 'export DAEMON_LOG_BUFFER_SIZE=512' >> ~/.profile
echo 'export UNSAFE_SKIP_BACKUP=true' >> ~/.profile
source ~/.profile

# 6. Start service and sync the node

Now you can start your full node. Enable the newly created service and try to start it using:

systemctl enable commercionetworkd  
systemctl start commercionetworkd

Check if the sync has been started. Use Ctrl + C to interrupt the journalctl command:

journalctl -u commercionetworkd -f

Wait until the node aligns with the height of the chain

# Next step

Now that you are a Commercio.network node with the statesync, if you want you can become a validator. If you wish to do so, please read the Becoming a validator guide.
