- 16 GB RAM
- 100 GB NVME SSD
- 3.2 GHz x4 CPU
- 32 GB RAM
- 500 GB NVME SSD
- 4.2 GHz x6 CPU
- Linux (x86_64) or Linux (amd64)
- Recommended Ubuntu or Arch Linux
If using Ubuntu:
Install all dependencies:
sudo snap install go --classic && sudo apt-get install git && sudo apt-get install gcc && sudo apt-get install make
Or install individually:
- go1.18+:
sudo snap install go --classic
- git:
sudo apt-get install git
- gcc:
sudo apt-get install gcc
- make:
sudo apt-get install make
If using Arch Linux:
- go1.18+:
pacman -S go
- git:
pacman -S git
- gcc:
pacman -S gcc
- make:
pacman -S make
git clone https://github.com/Canto-Network/Canto.git
cd Canto/cmd/cantod
go install -tags ledger ./...
sudo mv $HOME/go/bin/cantod /usr/bin/
Replace <keyname>
below with whatever you'd like to name your key.
cantod keys add <key_name>
cantod keys add <key_name> --recover
to regenerate keys with your mnemoniccantod keys add <key_name> --ledger
to generate keys with ledger device
Store a backup of your keys and mnemonic securely offline.
Then save the generated public key config in the main Canto directory as <key_name>.info
. It should look like this:
pubkey: {
"@type":" ethermint.crypto.v1.ethsecp256k1.PubKey",
"key":"############################################"
}
You'll use this file later when creating your validator txn.
Install cantod binary from Canto
directory:
sudo make install
Initialize the node. Replace <moniker>
with whatever you'd like to name your validator.
cantod init <moniker> --chain-id canto_7700-1
If this runs successfully, it should dump a blob of JSON to the terminal.
Download the Genesis file:
wget https://raw.githubusercontent.com/Canto-Network/Canto/genesis/Networks/Mainnet/genesis.json -P $HOME/.cantod/config/
_Note: If you later get
Error: couldn't read GenesisDoc file: open /root/.cantod/config/genesis.json: no such file or directory
put the genesis.json file wherever it wants instead, such as:
sudo wget https://github.com/Canto-Network/Canto/raw/main/Mainnet/genesis.json -P/root/.cantod/config/
Edit the minimum-gas-prices in ${HOME}/.cantod/config/app.toml
:
sed -i 's/minimum-gas-prices = "0acanto"/minimum-gas-prices = "0.0001acanto"/g' $HOME/.cantod/config/app.toml
Add persistent peers to $HOME/.cantod/config/config.toml
:
sed -i 's/persistent_peers = ""/persistent_peers = "[email protected]:26656"/g' $HOME/.cantod/config/config.toml
- Start
cantod
by creating a systemd service to run the node in the background: - Edit the file:
sudo nano /etc/systemd/system/cantod.service
- Then copy and paste the following text into your service file. Be sure to edit as you see fit.
[Unit]
Description=Canto Node
After=network.target
[Service]
Type=simple
User=root
WorkingDirectory=/root/
ExecStart=/root/go/bin/cantod start --trace --log_level info --json-rpc.api eth,txpool,net,debug,web3 --api.enable

[Install]
WantedBy=multi-user.target
Reload the service files:
sudo systemctl daemon-reload
Create the symlinlk:
sudo systemctl enable cantod.service
Start the node:
sudo systemctl start cantod && journalctl -u cantod -f
You should then get several lines of log files and then see: No addresses to dial. Falling back to seeds module=pex server=node
This is an indicator things thus far are working and now you need to create your validator txn. ^c
out and follow the next steps.
Modify the following items below, removing the <>
<KEY_NAME>
should be the same as<key_name>
when you followed the steps above in creating or restoring your key.<VALIDATOR_NAME>
is whatever you'd like to name your node<DESCRIPTION>
is whatever you'd like in the description field for your node<SECURITY_CONTACT_EMAIL>
is the email you want to use in the event of a security incident<YOUR_WEBSITE>
the website you want associated with your node<TOKEN_DELEGATION>
is the amount of tokens staked by your node (1acanto
should work here, but you'll also need to make sure your address contains tokens.)
