Archive Node
You may wish to archive the entire history of the Canto blockchain in order to index it with a Graph node or to roll your own block explorer. This means spinning up an archive node.
Complete step-by-step instructions for launching an archive node are provided below. If you're already comfortable installing and upgrading
cantod, see step four for archive-specific config details.As of block 2,500,000, the full archive state of Canto uses approximately 600GB of storage.
Install dependencies (Ubuntu):
sudo snap install go --classic
sudo apt-get install git
sudo apt-get install gcc
sudo apt-get install make
Clone the official repo and install the v1.0.0 binary:
git clone https://github.com/Canto-Network/Canto.git
cd Canto
git checkout v1.0.0
make install
sudo mv $HOME/go/bin/cantod /usr/bin/
Initialize the node and download the genesis file:
cantod init <MONIKER> --chain-id canto_7700-1
cd ~/.cantod/config
rm genesis.json
wget https://github.com/Canto-Network/Canto/raw/genesis/Networks/Mainnet/genesis.json
As when setting up a validating node, you'll need to set a seed peer (or persistent peers) as well as minimum gas prices:
# Add seed peer to config.toml
sed -i 's/seeds = ""/seeds = "[email protected]:15556"/g' $HOME/.cantod/config/config.toml
# Set minimum gas price in app.toml
sed -i 's/minimum-gas-prices = "0acanto"/minimum-gas-prices = "0.0001acanto"/g' $HOME/.cantod/config/app.toml
For an archive node specifically, the most important config setting is the pruning setting, which should be set to
nothing:# Set pruning in app.toml
sed -i 's/pruning = "default"/pruning = "nothing"/g' $HOME/.cantod/config/app.toml
Create the
systemd service file:sudo nano /etc/systemd/system/cantod.service
Copy and paste the following configuration and save:
[Unit]
Description=Canto Node
After=network.target
[Service]
Type=simple
User=root
WorkingDirectory=/root/
ExecStart=/usr/bin/cantod start --trace --log_level info --json-rpc.api eth,txpool,personal,net,debug,web3 --api.enable

[Install]

# Reload service files
sudo systemctl daemon-reload
# Create the symlink
sudo systemctl enable cantod.service
# Start the node
sudo systemctl start cantod
# Show logs
journalctl -u cantod -f
State breaking software upgrades took place at blocks:
- 218225 (v2.0.0)
- 1231500 (v3.0.0)
- 1274863 (v4.0.0)
- 2669495 (v5.0.0)
Important: v2.0.0 may cause AppHash errors at blocks that contained governance proposals (e.g. 804212). To avoid this, build the patched v2.0.2 binary instead.
Upon reaching these blocks while syncing an archive node, the node will halt and throw an error every time it restarts until you update the binary. To do so, follow these steps:
# Stop cantod
sudo systemctl stop cantod
# Delete old binary from path and install new binary (run in /Canto/ folder)
git checkout v2.0.0
sudo rm /usr/bin/cantod
make install
sudo mv $HOME/go/bin/cantod /usr/bin/
# Restart
sudo systemctl start cantod
For future binary upgrades, you will need to
git pull to fetch the updated binary before you attempt to install it.Last modified 29d ago
