Upgrade your node

A network may be occasionally upgraded with new features and performance optimizations.

To make the upgrade process as flawless as possible, the node installer script may be updated from time to time. This script can be ran in a non-destructive way, meaning it changes only what is needed. It will gracefully shut down Rusk for you.

How to Upgrade

To upgrade to the latest mainnet version, run:

Terminal window
# mainnet upgrade
curl --proto '=https' --tlsv1.2 -sSfL https://github.com/dusk-network/node-installer/releases/latest/download/node-installer.sh | sudo bash

Once it’s done and gives no errors, start Rusk again:

Terminal window
service rusk start

If everything is up and running again, query the node a couple of times to see if the block height is progressing:

Terminal window
ruskquery block-height

Or keep an eye on the logs to see if it’s making and accepting new blocks:

Terminal window
tail -F /var/log/rusk.log

If you see new blocks being accepted, you’re up and running again.

You can see the status of the Rusk service here:

Terminal window
service rusk status

If it is not running after starting it, and reports an error, you can check your logs to see if something is wrong, like a wrong password or no peers being found:

Terminal window
tail -n 30 /var/log/rusk.log

If everything else fails, check out the manual resync instructions.

Nocturne Reset

Sometimes the Testnet gets reset. For that you need to reset the state of Nocturne.

  1. To reset the state of Nocturne, download the latest version of our installer:
Terminal window
curl --proto '=https' --tlsv1.2 -sSfL https://github.com/dusk-network/node-installer/releases/latest/download/node-installer.sh | sudo bash -s testnet
  1. Reset all the data on your node:
Terminal window
ruskreset

Type in Y to accept the deletion of all the state.

  1. Start Rusk:
Terminal window
service rusk start
  1. Check if you’re already staking by running:
Terminal window
rusk-wallet stake-info

If you already have DUSK staked, wait until the chain starts producing blocks. You can check our explorer to see if the chain is progressing or when it will produce the genesis block.

  1. If you do not have testnet DUSK, request nDUSK from the faucet.

  2. Stake your nDUSK:

Terminal window
rusk-wallet stake --amt 1000 # Or however much you want to stake
