Bitmain Antminer Z11 on Pirate — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a Bitmain Antminer Z11 on Pirate (ARRR) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine Pirate with a Bitmain Antminer Z11?

Yes — a Bitmain Antminer Z11 (134.76 KH/s) can solo mine Pirate (ARRR) via a solo pool. At Pirate's 3.46 MH/s Equihash network that is about 20,501 blocks per year — expected one block roughly every 25.7 min, for the full 0.2500 ARRR 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 Pirate

The Bitmain Antminer Z11 is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 2 tracked models on Pirate, it ranks #1 in electrical efficiency (95.03 H/W) and #1 in raw hashrate (134.76 KH/s).

Electricity Operating Costs & Breakeven

Running a Bitmain Antminer Z11 (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 20,500.72 blocks, worth about $1,556 — expected revenue covers the power bill about 1.8x over.

The operational breakeven threshold is 0.125 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): +2.90 USD / day
• At 0.069 USD/kWh (Standard Industrial): +1.91 USD / day
• At 0.120 USD/kWh (Residential Grid): +0.18 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, Pirate must trade at or above 0.1673 USD at standard industrial power (0.069 USD/kWh), or 0.2910 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 25.7 min, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~1.3 min (1-in-20 fastest discovery, power cost: ~0 USD)
• Median expectation (50% Odds): Block within ~17.8 min (Nominal median, power cost: ~0 USD)
• Bad luck streak (5% Odds): Can stretch up to ~1.3 hours (1-in-20 extended dry spell, power cost: ~0 USD)

High Variance Alert: In a 1-in-20 severe drought (~1.3 hours), cumulative electricity burned (~0 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.

Bitmain Antminer Z11 Price & Estimated ROI

Current market price: $1,480–$1,759 across 2 vendors (median $1,620). Mined against its most profitable coin instead of solo, it would pay itself back in about 263 days.

How other hardware compares on Pirate

Devices in the same hashrate class, solo mining Pirate at today's difficulty:

How the odds have moved

Pirate's network hashrate climbed 4% since 2026-09-08, from 3.32 MH/s to 3.46 MH/s — so the same rig is now 4% less likely to find a block.

Where to point a Bitmain Antminer Z11 at Pirate

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 3 solo pools for Pirate with their stratum endpoints, fees, and pool hashrates — see Pirate solo mining pools:

• coolmine.top (Fee: 1% · Hashrate: 1.50 MH/s)
• mining-dutch.nl (Fee: 1% · Hashrate: 32.08 KH/s)
• himpool.com (Fee: 2% · Hashrate: 51.31 KH/s)

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 100.00%, yearly chance 100.00%.

Frequently Asked Questions: Bitmain Antminer Z11 on Pirate

Can you solo mine Pirate with a Bitmain Antminer Z11?

Yes — a Bitmain Antminer Z11 (134.76 KH/s) can solo mine Pirate (ARRR) via a solo pool. At Pirate's 3.46 MH/s Equihash network that is about 20,501 blocks per year — expected one block roughly every 25.7 min, for the full 0.2500 ARRR block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is Equihash ASIC-resistant, and where does the Bitmain Antminer Z11 stand?

Equihash is an ASIC-resistant GPU algorithm relying on memory bandwidth. The Bitmain Antminer Z11 ranks #1 of 2 GPUs on Pirate. It operates in the Mid-Range Tier (middle quartile), offering solid pool mining throughput with moderate solo variance.

What is the operating power cost and breakeven electricity rate for a Bitmain Antminer Z11 on Pirate?

At 1,418 W, operating a Bitmain Antminer Z11 consumes 34.03 kWh/day (1035.8 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 2.35 USD/day (71.47 USD/month). The operational breakeven threshold is 0.125 USD/kWh.

What happens if my Bitmain Antminer Z11 encounters a severe dry spell on Pirate?

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 1.3 hours, accumulating roughly 0 USD in power costs.
