Bitmain Antminer KA3 on Kadena — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a Bitmain Antminer KA3 on Kadena (KDA) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine Kadena with a Bitmain Antminer KA3?

Yes — a Bitmain Antminer KA3 (166.15 TH/s) can solo mine Kadena (KDA) via a solo pool. At Kadena's 16.24 PH/s Kadena network that is about 215,239 blocks per year — expected one block roughly every 2.4 min, for the full 0.9100 KDA 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 Kadena

The Bitmain Antminer KA3 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 Kadena, it ranks #1 in electrical efficiency (52,578,924,050.63 H/W) and #1 in raw hashrate (166.15 TH/s).

Electricity Operating Costs & Breakeven

Running a Bitmain Antminer KA3 (3,160 W) pulls about 75.84 kWh per day (2308.4 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 5.23 USD per day (159.28 USD/month or 1,911 USD/year). Statistically that year returns 215,238.98 blocks, worth about $1,791 — you would burn roughly 1x more in electricity than that reward is worth.

The operational breakeven threshold is 0.065 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): +1.87 USD / day
• At 0.069 USD/kWh (Standard Industrial): -0.33 USD / day
• At 0.120 USD/kWh (Residential Grid): -4.20 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, Kadena must trade at or above 0.00976 USD at standard industrial power (0.069 USD/kWh), or 0.0170 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 2.4 min, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~8 s (1-in-20 fastest discovery, power cost: ~0 USD)
• Median expectation (50% Odds): Block within ~1.7 min (Nominal median, power cost: ~0 USD)
• Bad luck streak (5% Odds): Can stretch up to ~7.3 min (1-in-20 extended dry spell, power cost: ~0 USD)

High Variance Alert: In a 1-in-20 severe drought (~7.3 min), cumulative electricity burned (~0 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.

How other hardware compares on Kadena

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

How the odds have moved

Kadena's network hashrate climbed 17% since 2026-09-08, from 13.89 PH/s to 16.24 PH/s — so the same rig is now 17% less likely to find a block.

Where to point a Bitmain Antminer KA3 at Kadena

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

• poolflare.net (Fee: 2% · Hashrate: 11.47 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 KA3 on Kadena

Can you solo mine Kadena with a Bitmain Antminer KA3?

Yes — a Bitmain Antminer KA3 (166.15 TH/s) can solo mine Kadena (KDA) via a solo pool. At Kadena's 16.24 PH/s Kadena network that is about 215,239 blocks per year — expected one block roughly every 2.4 min, for the full 0.9100 KDA block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is Kadena ASIC-resistant, and where does the Bitmain Antminer KA3 stand?

Kadena is an ASIC-resistant GPU algorithm relying on memory bandwidth. The Bitmain Antminer KA3 ranks #1 of 2 GPUs on Kadena. 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 KA3 on Kadena?

At 3,160 W, operating a Bitmain Antminer KA3 consumes 75.84 kWh/day (2308.4 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 5.23 USD/day (159.28 USD/month). The operational breakeven threshold is 0.065 USD/kWh.

What happens if my Bitmain Antminer KA3 encounters a severe dry spell on Kadena?

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 7.3 min, accumulating roughly 0 USD in power costs.
