Starting the Node

To start the chainflip-node, run the following command.

sudo systemctl start chainflip-node

To check on the service, we use status.

systemctl status chainflip-node

On certain cloud service providers, such as Digital Ocean, a glitch with journald prevents it from correctly reading logs from other services. To address this issue, execute the command below: sudo systemctl restart systemd-journald.service

At this point, you will need to wait for your node to catch up with the latest block. You can find the latest block on our Block Explorer. (opens in a new tab)

If you try to start your engine now it will crash. Wait for your node to sync before proceeding.

To view the live logs for the validator software, check on them via journalctl. You can quit at anytime using ctrl/control + c

Check the Node:

journalctl -f -u chainflip-node.service

At the start, you should see that your node is synchronising to the network, something like this:

The chainflip-node uses warp sync by default to make joining the network a faster process for new nodes.

Starting the Engine

To start the chainflip-engine, we issue another command.

sudo systemctl start chainflip-engine1.3

To check on the service, we use status.

systemctl status chainflip-engine1.3

Check the engine logs:

journalctl -f -u chainflip-engine1.3.service

You should see some output that looks like this:

Your Chainflip account  is not funded. Note, it may take some time for your funds to be detected. WAITING for your account to be funded at block: 1

In the next section, you'll learn how to fund your node. After you do so the warnings should stop and the output will look something like this:

If the engine starts crashing and reporting errors, don't panic. Your node might be catching up and syncing blocks from the network. Give it some time and it should recover and start working. In the meantime you can head to the next section and start with the process of adding funds.

Enable systemd Services

Tell both the services to start again after a reboot:

sudo systemctl enable chainflip-node

sudo systemctl enable chainflip-engine1.3

Anytime you make changes to your config file, don't forget to run: systemctl restart chainflip-engine1.3
