“If you don’t find a way to make money while you sleep, you will work until you die.” ― Warren Buffett

Full Node LTS has reached the end… You can continue to use Full-Node Node Setup but it’s highly recommended move to Light-Node wallet for FluxNode Setup using the link below…

Welcome to the Official Flux Full Node Setup Guide

Flux FullNode Setup Video Tutorial Guide

Step by Step Walkthrough covering all steps mentioned here in this guide

Official Flux Node Video Tutorial

What are FluxNodes ??

FluxNode operators supply dedicated computing power, which generates rewards in Flux for powering the network. There are multiple options for supplying computing power, including renting from a VPS provider, renting a dedicated server to host multiple FluxNodes, or purchasing a server outright and hosting it in a data center or well-equipped home/office.

The FluxTiered Node

FluxNodes are not like any other masternode in the space. Infact, it’s unfair to even call it a masternode.

There are three tiers of Fluxnodes (Cumulus|Nimbus|Stratus).Each providing massive amounts of computing and storage power that is fully decentralized in both ownership and geographic location around the world. When compared to other projects, where masternodes only process transactions. FluxNodes will be running Flux dapp backends, smart contracts, sidechains for asset layers, among other uses we haven’t even thought of yet. All this will be possible because of the sheer amount of resources available before being absolutely needed.

How much is the ROI?

The rewards & ROI will depend heavily on the total VPS cost, FluxNode Tier & the price of Flux!! To help you understand better, we have created a “FluxNode dashboard” to help you make that decision & choosing what is right for you. You can easily navigate & find the total enabled nodes, daily, monthly, yearly rewards, revenue, ROI & much much more...

2. Deterministic FluxNode Install Guide

This guide will be using the install script on Contabo VPS platform. I personally use them for my nodes and I find their prices relatively competitive. I am not in any way affiliated with them nor we recommend any of the VPS providers. Please do your research before you commit. As a side note, benchmarking is an important criterion & must meet minimum specs, uptime requirement: > 97%

Let’s Begin !!

Download the latest ZelCore Wallet. Go to zelcore.io & choose your platform..

3. The Login Screen

Existing users can login OR if you haven’t logged in for a long time, click on the “add existing account”

If you are a brand new user or haven’t never used the wallet ever, then “register new account”. It will also give you a option of “Create recovery password mechanism” which is great to recover lost password in case you ever forget your login credentials.

4. Change the Auto Logout

Go to settings and change the Automatic Log Out to “Never”. This will insure the ZelCore wallet doesn’t log you out automatically during the FluxNode setup.

5. Enabling d2Fa & adding Assets (Optional)

💡 Although not required for the node setup. However, it’s a good practice to enable Decentralized Two-factor authentication (d2FA) as an extra step, added to the log-in process.

It helps verify your identity and prevent cybercriminals from accessing your private information. d2FA offers an extra level of security that cyberthieves can’t easily access, because the criminal needs more than just your username and password credentials.

Note: Enabling d2Fa requires a small amount of 0.0002 Flux to be present in your wallet in order to broadcast a d2Fa enable transaction. Your d2Fa pin will be set after the transaction is confirmed on the blockchain & you have to re-login. This will be a one time transaction.

Click on the Apps > ZelId > d2Fa to enable the decentralized two way factor authentication

Click on the “+ sign” to add Flux & other assets you like to see and use.

6. Initiate Flux Full Node

⚠️ Running Anti-Virus Software on Your Machine

There have been reports that certain antivirus software is known to delete the zelcore\bin folder, which may risk losing your FLUX. It’s been recommended, to add EXCEPTION to your AVP program before starting the full-node

Windows: C:\Users\windowsusername\ZelCore\bin

Initiate the Flux full node. Starting full node for the first time will take about “3 mins ~5 mins”, so be patient…

Now exit from Full Node, click on “Back” and hit “Exit Full Node”

Logout from Zelcore Wallet and exit it completely. Close the wallet

7. Download the latest Bootstrap

⚠️Your wallet needs to be synced 100% to the blockchain before you can send any Flux ( Very Important)⚠️

Blockchain Sync Process

Go to ▶ Downloading File: https://fluxnodeservice.com/ & download the latest bootstrap.

In order to unzip the file, you need to download the “WinRar”. Visit https://www.win-rar.com/download.html?&L=0

After installing WinRAR locate the downloaded Boot-Strap and unzip the folder..

The bootstrap file contains most of the current blockchain data in a downloadable zip file. You can use this data with your full node to more quickly sync your full node. This step will speed up the blockchain sync process.

PC Windows: C:\Users\YOURUSERNAME\AppData\Roaming\Zelcash
Apple MacOS: ~/Library/Application Support/zelcash
Linux: ~/.zelcash


PC Windows: C:\Users\YOURUSERNAME\AppData\Roaming\Flux
Apple MacOS: ~/Library/Application Support/Flux
Linux: ~/.flux

Trouble Finding “Application Support” folder in your MAC. Watch the video below…

Note: In case you can’t access “AppData” it’s because it’s hidden. For PC, go to C:\YOURUSERNAME & then go to “View” and click on “Hidden Files/Items”. The AppData will then appear..

Find and locate the folder “daemon_bootstrap” you just unzipped using winRAR

Copy Blocks, Chainstate & Determ_zelnodes & replace it in the zelcash folder

Example Showing Zelcash Folder in the PC

7b. Know Your Full-Node Wallet

After successfully updating your bootstrap in your folder. It’s time to initiate the full-node wallet. Pay extra attention to the “Daemon Info” highlighted in the green box above. Do the same steps as mentioned earlier. If you notice now, that the blockchain sync is nearly complete. Wait to get it synced 100% as shown below…

After starting your Full-Node wallet,

-The “Height” represents the current block your full-node wallet in currently at

-The “Date” represents what date & time your full-node block is currently at

-The “Headers” represents the current block your wallet needs to be synced to Once you reach this value and your (Height number= Headers number) You are 100 % Synced

Click on “Receive Address” & you will find your address there. If want to have more addresses click on “New Transparent Address”

⚠️ Warning: Backup !! Backup !! Backup !!

Backup Private Keys— In full-node wallet, Click on Tools > Wallet Management > Import/Export > 3rd option from the top > click on box to choose path > choose location (Create a new Folder for backup) > Export

Backup Wallet — In full-node wallet, Click on Tools > Wallet Management > Import/Export > 4th option from the top > click on box to choose path > choose location (Create a new Folder for backup) > Backup

8. Depositing Flux to Full-Node For Node Setup

How to get the Flux Address ??

In order to deposit you would need a Flux address. How can i get the address ? Click on “Receiving Address” as shown below;

This is your transparent address which you need to transfer your flux to. Choose any address of your liking and click to copy. If you want more address simply click on “New Transparent Address”

You can use same address for running multiple FluxNodes. If you prefer using different address each time that’s fine as well. It’s your choice..

Note: Make sure you backup your private keys

Before we begin the nodes setup, it’s important to deposit the flux to your full-node. Depending on the choice of your Tier below;

For Cumulus: Deposit exactly 10,000 Flux

For Nimbus: Deposit exactly 25,000 Flux

For Startus: Deposit exactly 100,000 Flux

Now, transfer the Flux to your “Receiving Address” from the step above. Send exactly as mentioned. Don’t worry about network fees as this will be done automatically.

⚠️Note: If this is the first time, you have initiated the fullnode. Your blockchain has to be 100% synced otherwise you will not see your deposit until the blockchain is 100% synced. Very Important !! Go to previous step, incase you missed it

To confirm if the transaction went through while you are waiting for the blockchain to get synced. You can check your balance on “Flux Explorer”. Put your receiving address and check your balance


9. Starting FluxNode Setup

It’s a good idea now to backup all your addresses and save it. It will be helpful in case you want to recover your Flux in case of any issues. This will backup all your Private Keys to your destination folder “NEVER SHARE YOUR PRIVATE KEYS WITH ANY ONE”

The next step is to select the Flux Tier you want to run. In this setup, we will be setting up a “Super Node”. Enter the IP of the VPS..

Note: “You can easily find the IP of the VPS host by visiting your VPS provider or contact them directly if you are having problems”

Click Next Step ..

Send the exact collateral to one of your transparent addresses as shown Collateral (10K Cumulus/ 25K Nimbus/ 100K Stratus)

The collateral should now reflect in your address shown above. This is the available output that is not currently been reserved by FluxNode & you can use this to setup a Super FluxNode

Click on the address to continue…

Name your FluxNode and click on “Continue FluxNode Setup”

Copy the generated private key, Output TX ID & the output Index and save it in a notepad OR alternatively copy the entire string in the bottom and save it..

Click “Save and Continue”

Close the window by clicking the X on top

Do Not Click on “Activate my FluxNode” not just yet…

Note: It requires by minimum 100 Block confirmations on the chain to even start the node. Please wait patiently. It would take about 3.5 hrs.

⚠️FluxNode can be run on any Home PC/Servers, ARM devices or VPS

It is recommended to keep it more decentralized and not rely on one centralized location.

The below requirements are the minimum that a node provider must have to overcome the benchmarking system. If a node owner provides more resources than the above, the network will use all the resources that can be found on the specific server.

Home PC/Servers Minimum Requirements

10. VPS Host Setup

You can use any VPS provider of your choice to Host Flux nodes. You can also use Home PC Computer as well as long as you meet the min. specification.

Although, we are not affiliated with any VPS providers, here are the list of recommended VPS providers our Flux Node owners use. Please do your research what is best for you.

13. Benchmarking VPS Hosts (Optional)

Sysbench are used for benchmarking purposes.

  • Sysbench can be installed via:\

curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.deb.sh | sudo bash
apt install sysbench

Instructions are courtesy of haydenjames

Sysbench also has many possible tests. We will be using the utility to test the CPU performance. Prime number search tests the outright speed of the CPU and does not utilize things like hardware-accelerated encryption, making it a suitable performance test.

Built-in Linux data duplicator (dd) utility is used to test drive speed and overall write times.

Benchmarking performed using Ubuntu 16.04 | Sysbench v1.0.16


  • Command: sysbench --test=cpu --threads=8 --cpu-max-prime=60000 --time=20 run Change --multiply the final result with the number of cores available on your VPS/machine
  • Change threads to 8 for Stratus, 4 for Nimbus, 2 for Cumulus tiers
  • Check: events per second

These specs are for Sysbench v1.0.16. Installation instructions are above.

Stratus (8vCore, 32GB RAM, 600GB SSD)

  • CPU | Sysbench events per second (60k max prime, 20 seconds): > 400
  • SSD IOPS | Nench total iops: > 700 (no longer tested)
  • SSD speed | dd speed (count=10k): > 160 MB/s

Nimbus (4vCore, 8GB RAM, 150GB SSD)

  • CPU | Sysbench events per second (60k max prime, 20 seconds): > 200
  • SSD IOPS | Nench total iops: > 700 (no longer tested)
  • SSD speed | dd speed (count=10k): > 160MB/s

Cumulus (2vCore, 4GB RAM, 50GB)

  • CPU | Sysbench events per second (60k max prime, 20 seconds): > 90(no longer tested)
  • SSD IOPS | Nench total iops: > 700 (no longer tested)
  • SSD speed | dd speed (count=10k): > 160MB/s (no longer tested)

DD (data duplicator)

  • Command: dd if=/dev/zero of=sb-io-test bs=64k count=16k conv=fdatasync; rm -rf sb-io-test
  • Check: Drive speed

“Contabo is notorious for providing low I/O speeds & you need to contact customer support & ask them to increase the SSD speeds. They are fast in responding & would re-adjust accordingly..”

Note: SSD speeds should be better w/ I/O speeds > 160 MB/s in order to pass Benchmarks. The node will fail otherwise..

Confirm that your benchmark passes & it’s reflecting the type of node you will be running. In my case, I will be running NimbusNode, therefore, if my benchmarking has passed it will display “NIMBUS” on the status

Check Benchmarks: fluxbench-cli getbenchmarks

If your benchmark didn’t pass it will display status as “Failed” & you need to restart the benchmark process again. Use the following command:

Restart Benchmarks: fluxbench-cli restartnodebenchmarks

25. Final Checklist

Complete the following checklist. This will fix any steps you may have forgot or missed.

✅ Verify the IP address

✅Verify the private key/Output TX ID/Output Index

✅ Confirm 100 Block confirmations

✅ Verify the transparent address

✅ Benchmarks Pass/Fail

26. Starting Node from ZelCore Wallet

Launch full node. Check the Daemon information. Make sure you have peers connected and the blockchain 100% synced before starting up the node (important)

The node will display “Offline”. Click on 3-dots and click on “Start”. After 1–2 blocks your node will display “Started” & few blocks after your node will show “Confirmed”

Confirmed means “Your Node has been successfully launched” & you will start receiving the rewards within the next 24hrs.

If your node status is stuck in “Started” for a long time. This means either the benchmark didn’t pass or it failed shortly after. It could also mean you entered the wrong configuration. It’s a good idea to check your configuration and make sure they were entered correctly.

Your node eventually will display “DOS” & you will have to further troubleshoot to determine the root cause

27. Backing up Configuration (IMPORTANT)

This is the most crucial and final step you need to take before you exit your full-node wallet or exiting out of ZelCore.

⚠️ Warning: Backup !! Backup !! Backup !!
