Bitmain Antminer KS3 on Kaspa — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a Bitmain Antminer KS3 on Kaspa (KAS) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine Kaspa with a Bitmain Antminer KS3?

Yes — a Bitmain Antminer KS3 (9.40 TH/s) can solo mine Kaspa (KAS) via a solo pool. At Kaspa's 345.35 PH/s kHeavyHash network that is about 8,588 blocks per year — expected one block roughly every 1.0 hours, for the full 2.0602 KAS 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 Kaspa

The Bitmain Antminer KS3 is categorized in the Commercial / High-Yield Tier (Top quartile hashrate on this network, highly competitive for regular pool revenue or realistic solo mining.). Among all 18 tracked models on Kaspa, it ranks #5 in electrical efficiency (2,647,357,746.48 H/W) and #5 in raw hashrate (9.40 TH/s).

Electricity Operating Costs & Breakeven

Running a Bitmain Antminer KS3 (3,550 W) pulls about 85.20 kWh per day (2593.3 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 5.88 USD per day (178.94 USD/month or 2,147 USD/year). Statistically that year returns 8,587.89 blocks, worth about $660 — you would burn roughly 3x more in electricity than that reward is worth.

The operational breakeven threshold is 0.021 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): -1.60 USD / day
• At 0.069 USD/kWh (Standard Industrial): -4.07 USD / day
• At 0.120 USD/kWh (Residential Grid): -8.42 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, Kaspa must trade at or above 0.1214 USD at standard industrial power (0.069 USD/kWh), or 0.2111 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 1.0 hours, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~3.1 min (1-in-20 fastest discovery, power cost: ~0 USD)
• Median expectation (50% Odds): Block within ~42.5 min (Nominal median, power cost: ~0 USD)
• Bad luck streak (5% Odds): Can stretch up to ~3.1 hours (1-in-20 extended dry spell, power cost: ~1 USD)

High Variance Alert: In a 1-in-20 severe drought (~3.1 hours), cumulative electricity burned (~1 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.

How the odds have moved

Kaspa's network hashrate climbed 5% since 2026-09-22, from 329.18 PH/s to 345.35 PH/s — so the same rig is now 5% less likely to find a block.

Where to point a Bitmain Antminer KS3 at Kaspa

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

• rustykaspa.org (Fee: 0% · Hashrate: 485.78 TH/s)
• k1pool.com (Fee: 0.5% · Hashrate: 3.24 PH/s)
• kaspa-pool.org (Fee: 0.75% · Hashrate: 10.44 PH/s)

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 100.00%, yearly chance 100.00%.

Frequently Asked Questions: Bitmain Antminer KS3 on Kaspa

Can you solo mine Kaspa with a Bitmain Antminer KS3?

Yes — a Bitmain Antminer KS3 (9.40 TH/s) can solo mine Kaspa (KAS) via a solo pool. At Kaspa's 345.35 PH/s kHeavyHash network that is about 8,588 blocks per year — expected one block roughly every 1.0 hours, for the full 2.0602 KAS block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is kHeavyHash ASIC-resistant, and where does the Bitmain Antminer KS3 stand?

kHeavyHash is an ASIC-resistant GPU algorithm relying on memory bandwidth. The Bitmain Antminer KS3 ranks #5 of 18 GPUs on Kaspa. It sits in the Commercial / High-Yield Tier (top quartile), making it highly competitive for steady pool income and realistic solo mining.

What is the operating power cost and breakeven electricity rate for a Bitmain Antminer KS3 on Kaspa?

At 3,550 W, operating a Bitmain Antminer KS3 consumes 85.20 kWh/day (2593.3 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 5.88 USD/day (178.94 USD/month). The operational breakeven threshold is 0.021 USD/kWh.

What happens if my Bitmain Antminer KS3 encounters a severe dry spell on Kaspa?

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 3.1 hours, accumulating roughly 1 USD in power costs.
