Flux Node Setup: How to Earn with FLUX

GPU mining is dead

If you searched “Flux GPUGPUGraphics Processing Unit. Originally designed to render video game graphics, GPUs turned out to be exceptionally good at the massively parallel math that AI models need. Modern AI training and inference runs almost entirely on GPUs.Like a factory with 10,000 workers doing the same simple task in parallel, versus a CPU which is more like 10 workers each doing different complex tasks. AI training involves doing simple math a million times per second on a million numbers, which is exactly what the GPU factory is designed for.Read more → miningProof of WorkThe original blockchain consensus mechanism where miners compete to solve computationally expensive puzzles. The winner proposes the next block and earns the rewards. Proof of Work secures Bitcoin and most pre-2020 chains.Like a lottery that runs every 10 minutes where the tickets cost electricity. Whoever spends the most electricity buying lottery tickets has the best chance of winning that round's prize. Nobody can fake the result because the proof of their work is verifiable by everyone.Read more →”, I need to update you. Since the PoUWProof of Useful WorkA consensus mechanism where the computational effort that secures the network is directed at a useful task (rendering, scientific computing, AI inference) rather than arbitrary hash puzzles. Aims to make PoW productive instead of wasteful.Like paying lifeguards to also clean the pool. Instead of paying them to sit on a chair doing nothing, you get the same security plus a clean pool. The challenge is making sure the pool cleaning doesn't compromise their ability to actually rescue swimmers.Read more → v2 soft forkForkA point at which a blockchain or its software splits into two separate paths. Forks can be temporary (two valid blocks compete and one wins), planned (a software upgrade), or contentious (a community split into two chains).Like a road that splits in two. Sometimes the split is just a temporary detour and traffic merges back. Sometimes it's a permanent fork where different drivers go different ways and never meet again.Read more → at block 2,020,000 (October 2025), traditional GPU hash mining no longer works for earning FLUX. Mining pools and GPU mining software are obsolete.

Flux replaced GPU mining with Proof of Nodes. FluxNodes now handle all block productionBlockA batch of transactions added to a blockchain at a set interval. Each block cryptographically links to the previous one, creating an append-only chain that can't be rewritten without redoing all the work since.Like a page in a ledger. Every page has a fixed number of entries, every page references the previous page, and once a page is filled and signed off it can't be edited without visibly invalidating every page that came after. The chain is just a very long series of these sealed pages.Read more → and transaction validation. The rationale was that mining pools posed centralisation risks and provided no direct utility to the network. FluxNodes contribute compute, storage and deployment services. Useful work, not hash puzzles.

The way to earn FLUX is now node operation or Titan fractional stakingStakingLocking up a cryptocurrency to help secure a blockchain network, usually in exchange for rewards. The locked tokens act as a security deposit that can be taken away if the staker misbehaves.Like putting down a large rental deposit for an apartment. You get the money back if you behave, you earn interest while it's locked, and the landlord takes it if you trash the place.Read more →. For the full project assessment, see our Flux review.

The three paths to earning FLUX

Path	Capital required	Technical skill	Earnings potential
FluxNode (Cumulus)	1,000 FLUX (~$56) + hardware	Intermediate	Low at current prices
FluxNode (Nimbus)	12,500 FLUX (~$700) + hardware	Intermediate	Moderate at current prices
FluxNode (Stratus)	40,000 FLUX (~$2,240) + hardware	Intermediate	Best per-node at current prices
Titan staking	50+ FLUX (~$3)	Beginner	Lowest, but no hardware

Node tier requirements

Spec	Cumulus	Nimbus	Stratus
CPU	2 cores / 4 threads	4 cores / 8 threads	8 cores / 16 threads
RAM	8 GB	32 GB	64 GB
Storage	220 GB SSD	440 GB NVMe	880 GB NVMe RAID
Disk write speed	180 MB/s	400 MB/s	800 MB/s
Bandwidth	25 Mbps up/down	50 Mbps	100 Mbps
FLUX collateral	1,000	12,500	40,000

Additional requirements across all tiers:

• Public IP address (maximum 8 nodes per IP)
• TPM 2.0 (physical chip or virtual)
• UEFI Boot Mode enabled
• AMD64 (x86-64) architecture only
• 97%+ uptime
• NVMe drives strongly recommended. They are 5x faster than traditional SSDs

Block rewards after PoUW v2

Block time: 30 seconds (reduced from 2 minutes). Block reward: 14 FLUX per block.

Tier	Share	FLUX per block	Daily pool (~2,880 blocks)
Stratus	64.3%	9.0 FLUX	~25,920 FLUX
Nimbus	25.0%	3.5 FLUX	~10,080 FLUX
Cumulus	7.1%	1.0 FLUX	~2,880 FLUX
Foundation	3.6%	0.5 FLUX	~1,440 FLUX

Total daily emissions: approximately 40,320 FLUX. A 10% annual emission reduction replaces the old halvingHalvingA protocol event that cuts the rate of new token emissions by half. Halvings are scheduled in advance, happen automatically at fixed intervals, and are a core mechanism for enforcing declining token supply growth over time.Like a savings account where the interest rate is contractually cut in half every four years. You still earn interest, but the rate drops on a known schedule, and the issuer can't change it without breaking the contract.Read more → mechanism, targeting ~1% inflationInflationThe annual rate at which new tokens are created and added to the circulating supply. Most networks use inflation to pay validators, stakers, and infrastructure providers from freshly minted tokens rather than real revenue.Like a landlord who raises the rent every year. If your salary goes up at the same rate, you break even. If it doesn't, you get poorer without noticing, because the number on your payslip hasn't changed but the ground under it has shifted.Read more → by 2036. Max supply: 440 million FLUX.

Emissions fund network security and participation at the cost of diluting existing holders.Like a company that pays employees partly in newly printed shares. Every year the total number of shares goes up, which means existing shareholders own a slightly smaller slice of the same company unless the company grows faster than the printing.Read more →, node operators earn an additional 0.1 of each parallel asset (FLUX tokens on other chains: Ethereum, BSC, Solana, TRON, Avalanche, Polygon and others). With all parallel assets active, this can potentially double total earnings. Parallel assets swap 1:1 with native FLUX via Fusion.

Setting up a FluxNode with ArcaneOS

ArcaneOS launched in March 2025 and is mandatory for Progressive Node Rewards (PNR) eligibility and enterprise-grade app hosting. Legacy FluxOS nodes remain functional for earning native block and parallel mining rewards, but only ArcaneOS nodes qualify for PNR revenue sharing.

What you need before starting

• Hardware meeting your chosen tier’s requirements
• ZelCore WalletWalletSoftware that stores the private keys needed to control tokens on a blockchain. A wallet does not actually hold any tokens. The tokens live on the chain. The wallet holds the keys that prove you own them.Like the key to a safe deposit box. The key doesn't contain your valuables. The valuables sit in the bank's vault. The key is what proves you're allowed to open the box and take them.Read more → or SSP Wallet with FLUX collateral loaded
• ArcaneOS ISO from images.runonflux.io/latest
• Bootable USB (via Balena Etcher on Mac/Windows or Rufus on Windows)
• For VMs: Proxmox 8.4.1 (fully supported) or VMware v17

Installation walkthrough

1. Prepare the environment. For bare metal, flash the ArcaneOS ISO to USB and boot from it. For a VM, create a virtual machine with UEFI, TPM 2.0 enabled, and resources matching your tier.

2. Run the installer. ArcaneOS uses a graphical installer. Configure keyboard, hostname, console user (pre-defined as “console”), networking, and UPnP ports. All disks are encrypted via LVM.

3. Enrol the Platform Key. Access UEFI/OVMF firmware to import the Flux Platform Key for Secure Boot. This is a security requirement. ArcaneOS uses a chain of trust during installation.

4. Configure the FluxNode. Access the web UI from the launch screen. Choose your configuration method: Manual, ZelCore TokenTokenA digital unit of value or access rights tracked on a blockchain. Tokens can represent ownership in a project, a right to use a service, a share of future revenue, or simply a tradable asset with no underlying claim.Like a physical poker chip a casino issues. The chip itself has no value. What makes it worth something is what it lets you do at the casino, what the casino has promised, and how much other people will pay you for it.Read more →, or SSP Token. Enter your wallet details and select your node tier.

5. Set up notifications. Configure Discord or Telegram webhooks for alerts. You want to know immediately if your node goes down.

6. Configure SSH access. Enable the operator account using ed25519 keypairs. Set port and repository restrictions.

7. Review and save. Confirm your configuration, save via Flux Storage or as JSON/YAML for backup.

8. Wait for sync. Monitor the Metrics Dashboard as the node syncs the blockchain. This takes time on first boot. Do not start the node from your wallet until sync is complete.

9. Start the node. From ZelCore or SSP Wallet, start your FluxNode. The collateral is locked on-chain.

Limitations

• ArcaneOS focuses on home-based nodes. VPS usage is limited due to Secure Boot constraints.
• AMD64 only. No ARM support.
• VMware v16 is incompatible. Use v17 or Proxmox.

Titan fractional staking

If you do not want to run hardware, Titan lets you stake FLUX and earn rewards from managed nodes operated by InFlux Technologies.

Parameter	Detail
Minimum stake	50 FLUX (~$3)
Maximum per stake	10,000 FLUX
Maximum per FluxID	40,000 FLUX
Lock periods	3, 6, or 12 months
Payouts	Twice weekly (Monday and Thursday, ~9:00 AM UTC)
Parallel assets	Not included, native FLUX only

Longer lock periods yield higher returns and lower fees. Collateral cannot be withdrawn during the lock period. Rewards can be redeemed early only if at least 50 FLUX has accumulated.

Currently 111 active Titan Nodes with approximately 3.8 million FLUX staked.

The custody question. Titan is described as “non-custodial” and uses ZelCore or SSP Wallet. However, hardware is managed by InFlux Technologies on enterprise machines, and payouts are executed from Titan’s multi-signature wallet by the Flux team. This is effectively a managed arrangement despite the non-custodial branding.

The honest economics

At current FLUX price (~$0.06), let me work the numbers.

The total daily emission pool is ~40,320 FLUX worth roughly $2,258. Split across approximately 7,835 nodes (Cumulus: 4,488, Nimbus: 1,725, Stratus: 1,622; check the live dashboard at nodeinfo.app.runonflux.io for current figures):

• Cumulus: The 2,880 FLUX daily Cumulus pool divided across 4,488 Cumulus nodes yields roughly 0.64 FLUX/day (~$0.04). Hardware and hosting costs are not covered.
• Nimbus: The 10,080 FLUX Nimbus pool across 1,725 nodes yields roughly 5.8 FLUX/day (~$0.33). Still below hosting costs.
• Stratus: The 25,920 FLUX Stratus pool across 1,622 nodes yields roughly 16 FLUX/day (~$0.90) before parallel assets. With all parallel assets active, this could roughly double to ~$1.80/day. Still tight against hardware costs.

Progressive Node Rewards add FluxCloud revenue sharing: 80% of FluxCloud application revenues go to ArcaneOS node operators. However, FluxCloud has approximately 658 deployed apps currently (over 25,000 historically) and the revenue share is still in early rollout.

FluxEdge offers a separate GPU revenue stream. If you have an NVIDIA GPU (GTX 1060 minimum, RTX 3060+ recommended), you can contribute it to FluxEdge via the FluxCore desktop app and earn rental fees ($0.10-2.00+ per GPU hour depending on the card). This is independent of FluxNode rewards and is the closest thing to “GPU mining” that still exists on Flux.

The real thesis

Node economics at current FLUX prices do not generate positive returns for most operators. This is why the node count has declined from 14,000+ to approximately 7,800. Operators who needed immediate returns have left.

Running a FluxNode makes sense if:

• You believe FLUX will appreciate significantly from current levels
• You have existing hardware with spare capacity
• You want to contribute compute to a decentralised network and treat the FLUX as a long-term position
• You are interested in the FluxCloud/FluxEdge revenue streams as they develop

It does not make sense if you need current-price returns to cover hardware and hosting costs.

Monitoring and maintenance

Nodes must maintain 97%+ uptime. If you go offline, you miss payout cycles and are sent to the back of the reward queue. No slashing. You just stop earning.

ArcaneOS includes built-in monitoring with Discord/Telegram alerts. For external monitoring, UptimeRobot (free tier, 50 monitors) can track your node’s APIAPIApplication Programming Interface. A structured way for one piece of software to talk to another. In DeAI, APIs let applications request inference from a model without running the model themselves.Like a waiter in a restaurant. You don't walk into the kitchen and cook your own meal. You tell the waiter what you want, they tell the kitchen, the kitchen cooks it, and the waiter brings it back. The API is the waiter.Read more → endpoint and web UI.

Recent ArcaneOS updates have added automatic rollback on npm install failures and smarter UPnP port selection, reducing maintenance burden.

Flux TestNet is available for testing the full setup before committing real FLUX collateral. Use it.

Where to buy FLUX

Available on Binance, Kraken, KuCoin, Gate.io, and Crypto.com. FLUX exists as parallel assets on 10+ chains (Ethereum, BSC, Solana, TRON, Avalanche, Polygon and others), all swappable 1:1 via Fusion. Daily volume is approximately $2 million.
