Time to upgrade your FluxNode tier?

There are many reasons why you would want to upgrade your current FluxNode to a higher tier. One is the recent announcement of Firo nodes on Flux. If you upgrade to a Nimbus or Stratus node soon you will be able to earn $Firo on top of your Flux block rewards and parallel mining rewards. As long as you have the required collateral and hardware it is simple to do. Read on and see how you can upgrade your FluxNode.

There are many great reasons why you would want to upgrade your existing FluxNodes to a higher tier:

  • Nimbus and Stratus nodes can earn $KDA and $FIRO in the future.
  • Cumulus nodes are becoming more abundant thus leveling the difference between daily Flux block rewards on Cumulus vs Nimbus.
  • Having larger Flux collaterals locked reduces the number of fees that need to be paid when claiming parallel asset airdrops as opposed to having smaller collaterals spread across more nodes.
  • You will help build the decentralized future by bringing stronger nodes to the Flux network.

Whatever your reason to upgrade your node tier, it is quite easy to do it. Here is a short guide on making the jump to a higher tier.

Getting the requirements in place

In order to upgrade your FluxNode to a higher tier, there are two bases that you need to have covered: The collateral and the Tier hardware requirements.

Here are the requirements for the three FluxNode tiers:

The collateral you can collect by acquiring more Flux or merging smaller nodes into larger ones. For example, 5 Cumulus collaterals can become 2 Nimbus collaterals. When you delete an existing FluxNode the collateral is released and can then be used for new node collateral.

The hardware requirements you can fill by upgrading your service plan with your VPS provider. If you host your node from home, then you can upgrade your hardware as necessary. Nimbus nodes can run on Raspberry Pi 4 but will require the 8GB version as well as the necessary additional storage and I/O speeds.

Once you have your collateral and can provide the required minimum specs for the node tier you want then you are ready to upgrade.

When doing the upgrade having the excellent step-by-step guide on FluxNode setup on hand for reference is advised.

First a little planning and locking the collateral

A little planning goes a long way, so choose the optimal time to do your tier upgrade.

Block rewards are given in a round-robin system for all nodes in a specific tier. So if there are 720 Cumulus online on the Flux network each Cumulus will receive a block reward every 720th block. Check the Flux Block explorer, look up your node’s Flux address, and see how many confirmations there are on your last block reward. Wait till you’ve just received a block reward before taking your node offline to max out your Flux rewards.

Also, $KDA rewards for Nimbus and Stratus nodes are given out every Tuesday — if the nodes have delivered 94% uptime during a week. So make sure and set up your Nimbus or Stratus node at least a day before a Tuesday to not miss out on a week of $KDA rewards.

Select one of your current FluxNode addresses to be reused for the upgraded tier node. Your parallel mining rewards are tied to this address and it is most efficient to keep stacking parallel mining rewards on the same addresses to reduce fees when claiming your rewards.

Now it’s time to collect your collateral and lock it in for your upgraded node. You need 100 confirmations on your collateral transaction (or roughly 3½ hours) before you can start your new node, so be aware of this also when timing your upgrade.

To release any existing collaterals that you might need, you simply delete the nodes in the Zelcore full node interface (hit the 3 dots next to your nodes name).

For example, if you have 15,000 Flux, you can delete an existing Cumulus node, free up the 10,000 Cumulus collateral, combine that with your other holdings and then post a new 25,000 collateral to stand up a Nimbus node on the same address as the Cumulus you deleted. Deleting nodes frees up the collateral fast, but naturally takes the node off the Flux network and stops it from earning more block rewards.

Once you have the required collateral on hand, send the exact amount to the node address you have selected for the upgraded node (25,000 for nimbus or 100,000 for Stratus).

Setting up the node

Now it’s time to set up your upgraded node. Enter Zelcore full node and run the Zelcore wizard to create a new flux node. Select the desired node tier and select the collateral address. Save your node information and configuration file and as always it is also a good idea to backup your private keys.

From here on you have two options regarding the technical setup of the server itself.

You can choose to go from scratch, simply reinstalling flux on the server running the node. If you have a VPS provider, you might have had to wipe your server in order to bump up the server specs. In that case, then starting from scratch is your only option. Fortunately, this setup can be done while waiting for your 100 confirmations on your collateral transaction. If you take this approach, then simply follow the guide on node setup.

You can also reconfigure an existing server. When you delete a node in Zelcore, your server will be unaffected but does require a reconfiguration in order to identify as the new node on the Flux network.

This can be easily done by running the Kamil script and selecting the option to re-configure the Flux Daemon. Follow the prompts and enter the information for the new node created in the Zelcore wizard (such as collateral transaction ID, private key, etc.).

The command to Launch the Kamil script is this:

bash -i <(curl -s https://raw.githubusercontent.com/RunOnFlux/fluxnode-multitool/master/multitoolbox.sh)

Once your collateral transaction has 100 confirmations, you can start your new tier upgraded node in the Zelcore full node interface and you are good to go. Remember to set up Kadena as well by following the guide.


That’s it. Once your node is confirmed on the Flux network you will start reaping the benefits of your brand new upgraded node. If you reuse the address from the node you’re upgrading from a lesser tier, then your parallel mining rewards will continue to accumulate on the same address, so make sure to do that.
