Can you solo mine Fractal with a NerdMiner NerdOCTAxe Rev 3.1?

Yes — a NerdMiner NerdOCTAxe Rev 3.1 (12.00 TH/s) can solo mine Fractal (FB) via a solo pool. At Fractal's 129.31 PH/s SHA-256 network that is about 65 blocks per year — expected one block roughly every 6 days, for the full 6.2500 FB (≈ 2 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model. Realistically this is genuinely worth a patient solo run.

Hardware Tier & Ecosystem Ranking on Fractal

The NerdMiner NerdOCTAxe Rev 3.1 is categorized in the Home / Solo Lottery Tier (Compact or low-power hardware optimized for decentralized solo lottery participation rather than commercial pool revenue.). Among all 9 tracked models on Fractal, it ranks #7 in electrical efficiency (49,980,000,000.00 H/W) and #1 in raw hashrate (12.00 TH/s).

Electricity Operating Costs & Breakeven

Running a NerdMiner NerdOCTAxe Rev 3.1 (240 W) pulls about 5.76 kWh per day (175.3 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.40 USD per day (12.10 USD/month or 145 USD/year). Statistically that year returns 65.05 blocks, worth about $152 — expected revenue covers the power bill about 1.1x over.

The operational breakeven threshold is 0.072 USD/kWh. Expected net operating margin at benchmark tariffs:

Break-even Coin Price Target: For this hardware to break even on electricity, Fractal must trade at or above 0.3571 USD at standard industrial power (0.069 USD/kWh), or 0.6210 USD at residential power (0.120 USD/kWh).

Bankroll & Variance Risk Simulator

Solo mining block discovery follows a memoryless Poisson distribution. While the average wait is 6 days, real-world dispersion ranges across 5% and 50% quantiles:

High Variance Alert: In a 1-in-20 severe drought (~17 days), cumulative electricity burned (~7 USD) will exceed the block reward value (2 USD). Pool mining is recommended for risk-averse operators.

How the odds have moved

Fractal's network hashrate fell 48% since 2026-09-22, from 250.33 PH/s to 129.31 PH/s — so the same rig is now 48% more likely to find a block.

Where to point a NerdMiner NerdOCTAxe Rev 3.1 at Fractal

Solo mining still runs through a solo pool: it handles the block template and pays the full reward to whoever finds the block. BackPoW tracks 12 solo pools for Fractal with their stratum endpoints, fees, and pool hashrates — see Fractal solo mining pools:

How the odds are calculated

Each hash is an independent attempt, so block discovery is memoryless and follows an exponential distribution. The average time to a block is T = network_hashrate ÷ your_hashrate × block_time. The chance of hitting at least one block within a period t is then given by the Poisson relation P = 1 − e^(−t/T) — the realistic probability, not a misleading linear one. For this pair: daily chance 16.31%, yearly chance 100.00%.

Frequently Asked Questions: NerdMiner NerdOCTAxe Rev 3.1 on Fractal

Can you solo mine Fractal with a NerdMiner NerdOCTAxe Rev 3.1?

Yes — a NerdMiner NerdOCTAxe Rev 3.1 (12.00 TH/s) can solo mine Fractal (FB) via a solo pool. At Fractal's 129.31 PH/s SHA-256 network that is about 65 blocks per year — expected one block roughly every 6 days, for the full 6.2500 FB (≈ 2 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is SHA-256 ASIC-resistant, and where does the NerdMiner NerdOCTAxe Rev 3.1 stand?

SHA-256 is an ASIC-dominated algorithm. The NerdMiner NerdOCTAxe Rev 3.1 delivers 12.00 TH/s (#1 of 9 models on Fractal). It belongs to the Home / Solo Lottery Tier, built for compact, decentralized solo attempts rather than commercial pool income.

What is the operating power cost and breakeven electricity rate for a NerdMiner NerdOCTAxe Rev 3.1 on Fractal?

At 240 W, operating a NerdMiner NerdOCTAxe Rev 3.1 consumes 5.76 kWh/day (175.3 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.40 USD/day (12.10 USD/month). The operational breakeven threshold is 0.072 USD/kWh.

What happens if my NerdMiner NerdOCTAxe Rev 3.1 encounters a severe dry spell on Fractal?

Block discovery is an independent Poisson process with no memory. In a 1-in-20 bad luck drought (5% worst luck), finding a block can stretch up to 17 days, accumulating roughly 7 USD in power costs.
