Flux mining with ZelHash algorithm (NVIDIA and AMD)

Flux uses an ASIC-resistant hashing algorithm known as ZelHash that can be mined on both NVIDIA and AMD GPUs.

If you own NVIDIA or AMD GPUs, mining Ethereum still makes sense. It is the best coin with a proof-of-work algorithm that can currently be mined with GPUs. But besides Ethereum, there are a few other coins that are also worth mining. You can mine Ravencoin, you can consider mining Firo, Ergo, Bitcoin Gold and Flux.

Every once in a while, all these alternative ETH coins that can be mined on GPUs will rise in the What To Mine profitability rankings. Sometimes it will be RVN, sometimes it will be Firo or ERGO. The profitability of mining depends on your hardware. So go to the WhatToMine website and choose the coin that is more profitable for your GPU.

Flux mining has seen a big boom recently, and it remains the most profitable coin for most graphics cards. In fact, it is more profitable than ETH and RVN. It has climbed to the top spot in the WhatToMine rankings and remains there for several weeks. That’s why we decided to prepare a guide to mining Flux coin.

Flux mining with ZelHash algorithm (NVIDIA and AMD)

Flux uses the ZelHash (125,4) Proof of Work hashing algorithm, which can be mined with NVIDIA and AMD GPUs. The miners are available for both Windows and Linux.

If you are familiar with mining Ethereum and other altcoins, mining Flux is just as easy.

The mining process is the same as for other altcoins. First you need to create a wallet, download the mining software capable of mining the ZelHash algorithm, select a mining pool for Flux coin, edit the bat file of the miner, customize the miner and you can start working.

Here we will look at Flux mining (ZelHash algorithm) using NVIDIA and AMD cards. It can be mined both on Windows / Linux and Hive OS.

But, wait! Flux mining may seem profitable at the moment, but it is only temporary. All these coins that are more profitable than ETH remain profitable only temporarily. Temporarily, it remains more profitable than Ethereum mining, but this is not for long. So in the long run, especially if you have a huge mining farm, it is better to stick to ETH.

Also note that Flux recently experienced a bullish surge from $10 to almost $2. Can it go any further? Unknown. But with all the parallel assets and whatnot, it seems very promising.

Either way, do your own research before mining, especially if you want to stay with the company.

Now, before we move on to FLUX mining, here’s a brief introduction to the Flux project.


Launched in 2018, previously called Zelcash, it was rebranded to Flux.

Flux – is a next-generation decentralized and scalable cloud infrastructure. You can develop, manage and run your own applications on Flux servers. It is ready for Web 3.0, Dapps and more.

It has a fully-ready set of compute services that interoperate with a decentralized development environment like AWS (Amazon Web Services).

The Flux ecosystem consists of the following elements, which are fully developed, deployed and operational in the Flux network.

  1. FluxNodes is a next generation decentralized infrastructure and web3 computing network with over 2100+ nodes.
  2. FluxOS: Gateway to Decentralized World is a revolutionary tier-2 cloud operating system running on top of Linux. With Flux OS, developers and node operators can verify, manage the network and perform a variety of functions: deploy, run DApps, verify nodes, evaluate compute power, vote / manage XDAO management, verify rewards, browse resources and use global applications.

Any application built on a hard docker can run efficiently and optimally on the Flux compute network. Several applications (dapps) are currently running through FluxOS, including: social networks, blockchain infrastructure, websites, games, data oracles, and file stores.

  1. Flux Fusion is a DeFi bridge that connects different blockchains and provides access to major DEXs such as Uniswap and Pancakeswap.
  2. Zelcore is the official wallet for Flux. It is also a multi-asset wallet with support for over 245 assets. Also a full suite of blockchain applications available for both PC and mobile devices. The wallet has built-in integration with major exchanges, allowing for quick token exchanges and interoperability with other DeFi apps.

Flux Specifications:
FLUX is the official currency/coin that powers the entire Flux ecosystem. It is mainly used to pay for transactions on FluxOS and to reward miners for confirming transactions on the Flux blockchain. In addition to miners, it also rewards FluxNode node operators for providing computing resources. With Flux, you can also buy resources and plant nodes.

It is an independent project, fully open and supported by the community. There is no pre-mining and coins are fairly distributed among holders, miners and node operators.

With Flux, you can run nodes and mine on GPUs. It uses the proof-of-use principle rather than the proof-of-work principle, which rewards only miners. Flux’s economic model incentivizes holders with airdrops, GPU miners with mining rewards, and node operators with node rewards. The reward per block is split equally between PoWs and node operators.

The following are the technical specifications:

Heshing algorithm: Zelhash (Equihash 125_4)
Construction for block: 75 fluxes
Distribution of remuneration: 50% POW – 50% node Operators
Block time: 2 min
Maximum reserve: 440,000,000,000,000,000 FLUX

P2P PORT: 16125
RPC PORT: 16124

At the time of writing, Flux is the most profitable altcoin to mine. So, let’s start mining Flux.

How to mine Flux?

First you need a flux wallet address to send your mining rewards.

You can download the Zelcore wallet. It is available for Android, IOS, Windows, MAC, and Linux operating systems. Zelcore wallet is the official Flux wallet. Apart from Flux, it also supports various other coins and tokens.

Download and set up the Zelcore multi-asset cryptocurrency wallet on your favorite platform. Once setup is complete, go to the “Receipt” tab and copy the receipt address.

Safety tip: Do not mine on a computer where you have your wallet and other personal financial belongings. Always keep your wallet separate from the mining machine. If you are mining from a computer, use a mobile app to receive payouts.

You can also mine directly to your exchange account. This way, you can easily exchange for other currencies. Flux is available for trading on Kucoin, Gate.io and Bittrex exchanges. Get a Flux deposit address, which we will use to send your mining rewards.

When the wallet address is ready, it’s time to choose a mining pool.

Flux mining pools

First of all, is it possible to mine Flux alone? Of course you can, but first make sure you have enough hashing power. You can either configure a pool directly, or you can mine solo with pools like 2miners, which supports solo mining on Flux.

For most users, solo mining is not suitable, so let’s choose a pool for mining.

There are not many mining pools available for Flux. You have minerpool.org, fluxpools.net, 2miners.com, zergpool, zpool.ca and some others.

So which pool to choose and which one to mine on? It’s up to you, but keep in mind that the bigger the pool, the more frequent the payouts will be.

Among the flux mining pools, minerpool.org has the highest hashrate. It accounts for more than 51% of the total network hashrate, indicating a high degree of centralization. But still people choose minerpool.org because only minerpool.org supports fusion (parallel assets) and also has a loyalty program. So in this guide we will also choose minerpool.org.

Flux – parallel assets?

Flux leverages the capabilities of multiple blockchains. It provides access to multiple blockchains through parallel assets. Essentially, it creates Flux assets on other blockchains with smart contracts that will be interchangeable with the main Flux blockchain. This in turn gives Flux owners easy access to other blockchains and all major decentralized finance platforms.

Only Minerpool.org supports fusion (parallel assets). So what does this mean? For miners, it means that you will get higher returns than usual. Currently, you get +39% more reward for mining fusion. In other mining pools, you only get the usual block rewards. But with Minerpool.org, you’ll get the usual block rewards + additional parallel assets.

Simply put, parallel assets give a big payout at the end of the day. This is one of the reasons why Flux mining is very profitable and a large number of miners use minerpool.org.

You do not need to set up anything additional to receive rewards for parallel assets. You will receive rewards for parallel assets after each regular payment to your wallet. They will be automatically exchanged to Flux at a 1:1 ratio and paid according to the following schedule:

FLUX-KDA (KADENA) and FLUX-BSC (BINANCE SMART CHAIN): once a week. FLUX-ETH (ETHEREUM): once every 2 weeks in case of rather high fees.


TRON – FLUX-TRX and more to come.

Now let’s pick a mining software and get started.

ZelHash miners

For NVIDIA GPUs, we recommend miniZ. You can also use GMiner.

However, miniZ is slightly superior to Gminer.

MiniZ really is the best, especially for 30xx series cards.

For AMD GPUs, you can use lolMiner.

All three miners are available for both Windows and Linux.

When downloading, your browser may block the miner file. In addition, your antivirus program will flag the program as a virus and remove the miner file from the download. Just add an exception to the file and continue downloading.

After downloading, unzip the file. Now it’s time to configure the miner.

Flux Miner Configuration – ZelHash 125.4

After unzipping the miner file, you should see some sample batch files. Create a new flux.bat file or edit existing ones. It will be called either flux.bat or zelcash.bat. Create or edit the bat file and enter the following configuration parameters.

Note: Before using the configuration below, visit the pool page for detailed connection information. The pool defines multiple servers and port numbers. Choose the one closest to your location to get the lowest latency. Also, if you are using minerpool, you need to set a password in the pass section to later change the payout thresholds on the pool control panel. Your password should not be X, as anyone can guess it and change the payout settings.

Settings for miniZ (NVIDIA only):

miniz --url=Your-Wallet-Address-Here.WORKERNAME@flux-eu.minerpool.org:2033 --pass=YourPassword --par=125,4 --pers=ZelProof --extra

MiniZ settings for 2miners:

miniZ.exe --url Your-Wallet-Address.worker@zel.2miners.com:9090 --log --extra

GMiner (NVIDIA) Settings:

miner --server flux-eu.minerpool.org --port 2033 --user Your-Wallet-Address-Here.WORKERNAME --pass YourPassword --algo 125_4 --pers ZelProof --pec

For the 2-minute ones, this configuration is used:

miner.exe --algo 125_4 --server flux.2miners.com --port 9090 --user YOUR_WALLET_ADDRESS.RIG_ID --pass x

Settings for lolMiner (AMD):

Edit the runminer.bat file and enter the following configuration:

set “PROFILE=flux”

Next, edit the user_config.json file and add the flux profile:

"flux" :{"COIN" : "FLUX","POOLS" : [{"POOL" : "flux-eu.minerpool.org","PORT" : "2033","USER" : "Your-Wallet-Address-Here.WORKERNAME","PASS" : "YourPassword"}]}

Customizing lolMiner 2miners:

lolMiner.exe --coin ZEL --pool flux.2miners.com:9090 --user YOUR_WALLET_ADDRESS.RIG_ID

All you have to do is enter your settings and replace the highlighted: It’s basically your wallet address and password.

Once the configuration file is ready, save it and run it.

Tip: Check out the pools help page, where you will also find the configuration settings. You can use that as well. Also for your information, both 2 miners and minerpool work with mining rig rentals and the NiceHash rig rental service.

Hive OS

To mine Flux in Hive OS, all you need to do is connect your wallet and set up a flight list. All miners for Flux (ZelHash) mining are easily available in Hive OS.

How do I connect my wallet and set up a flight list?

First, go to the Wallets section and add a wallet. Select the Flux coin name, enter the Flux wallet address, give it a name and click create.

Next, go to the flight sheets section and add a new flight sheet. Select Flux coin, select the Flux wallet you just added. Then select the pool where you want to mine the coin, select a miner from the list, lolMiner and Gminer support NVIDIA / AMD. miniZ only supports NVIDIA. Give a name to the raidlist and click on Create raidlist.

You don’t need to customize the miner because the settings made in Hive OS are automatically imported. Thus, you do not need to touch the settings of the miner.

Next, go to the flight sheet selection and apply the Flux flight sheet you just configured. You’re all set. Now you are mining Flux.

To check statistics, check the performance of your rigs, track mining payouts and find out how much flux you have earned, visit the mining pool to which your rigs are connected. Go to the pool and enter your wallet address. The pool’s dashboard displays all statistics.

Mining profit calculators

Now that you have started mining, you can use the following calculators to estimate how much flux you will earn: Simply enter the hashrate of your hardware. For flux (Zelhash), this is Sol/s, not Mh/s.

Overclocking settings

When mining a new algorithm for the first time, start with the default clock speed settings. Adjust the overclock in small increments until you find the perfect match for your GPU.

Zelhash is very similar to KawPoW: it is kernel-intensive, so you should not use the same overclocking settings as for ETH, which is memory-intensive. The overclocking settings should be similar to RVN, where you overclock both kernel and memory. But, as we have already said, increase the settings gradually until you find the optimal option. If memory errors appear, you should lower the settings.

Also, don’t forget to set the fan speeds and make sure the temperature does not exceed the optimal GPU temperature.
