Can you solo mine Zcash with a Bitmain Antminer Z11J?
Yes — a Bitmain Antminer Z11J (104.79 KH/s) can solo mine Zcash (ZEC) via a solo pool. At Zcash's 30.50 GH/s Equihash network that is about a 1-in-1 chance per year — expected one block roughly every 255 days, for the full 1.2500 ZEC (≈ 1,578 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 Zcash
The Bitmain Antminer Z11J is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 15 tracked models on Zcash, it ranks #12 in electrical efficiency (73.90 H/W) and #11 in raw hashrate (104.79 KH/s).
Electricity Operating Costs & Breakeven
Running a Bitmain Antminer Z11J (1,418 W) pulls about 34.03 kWh per day (1035.8 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 2.35 USD per day (71.47 USD/month or 858 USD/year). Statistically that year returns 1.43 blocks, worth about $2,262 — expected revenue covers the power bill about 2.6x over.
The operational breakeven threshold is 0.182 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +4.83 USD / day
- At 0.069 USD/kWh (Standard Industrial): +3.85 USD / day
- At 0.120 USD/kWh (Residential Grid): +2.11 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Zcash must trade at or above 478.67 USD at standard industrial power (0.069 USD/kWh), or 832.46 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 255 days, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~13 days (1-in-20 fastest discovery, power cost: ~31 USD)
- Median expectation (50% Odds): Block within ~177 days (Nominal median, power cost: ~415 USD)
- Bad luck streak (5% Odds): Can stretch up to ~2.09 yr (1-in-20 extended dry spell, power cost: ~1,792 USD)
High Variance Alert: In a 1-in-20 severe drought (~2.09 yr), cumulative electricity burned (~1,792 USD) will exceed the block reward value (1,578 USD). Pool mining is recommended for risk-averse operators.
Bitmain Antminer Z11J Price & Estimated ROI
Current market price: $990–$1,500 (estimated market price, median $1,200) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 312 days.

How the odds have moved
Zcash's network hashrate climbed 10% since 2026-09-22, from 27.80 GH/s to 30.50 GH/s — so the same rig is now 10% less likely to find a block.
Where to point a Bitmain Antminer Z11J at Zcash
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 17 solo pools for Zcash with their stratum endpoints, fees, and pool hashrates — see Zcash solo mining pools:

How the odds are calculated
Solo mining is memoryless: every hash is an independent lottery ticket, so the wait for a block follows an exponential distribution rather than a fixed schedule. On average a block takes T = network_hashrate ÷ your_hashrate × block_time, and the probability of finding at least one within a window t is P = 1 − e^(−t/T). BackPoW uses this Poisson relation instead of a naive linear estimate. For this pair: daily chance 0.3917%, yearly chance 76.15%.
