Can you solo mine Kadena with a BlackMiner F2?
Yes — a BlackMiner F2 (67.74 GH/s) can solo mine Kadena (KDA) via a solo pool. At Kadena's 16.24 PH/s Kadena network that is about 88 blocks per year — expected one block roughly every 4 days, 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 BlackMiner F2 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 #2 in electrical efficiency (99,327,261.00 H/W) and #2 in raw hashrate (67.74 GH/s).
Electricity Operating Costs & Breakeven
Running a BlackMiner F2 (682 W) pulls about 16.37 kWh per day (498.2 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 1.13 USD per day (34.38 USD/month or 413 USD/year). Statistically that year returns 87.76 blocks, worth about $0.73 — you would burn roughly 565x more in electricity than that reward is worth.
The operational breakeven threshold is 0.000 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): -0.65 USD / day
- At 0.069 USD/kWh (Standard Industrial): -1.13 USD / day
- At 0.120 USD/kWh (Residential Grid): -1.96 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Kadena must trade at or above 5.17 USD at standard industrial power (0.069 USD/kWh), or 8.98 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 4 days, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~5.1 hours (1-in-20 fastest discovery, power cost: ~0 USD)
- Median expectation (50% Odds): Block within ~3 days (Nominal median, power cost: ~3 USD)
- Bad luck streak (5% Odds): Can stretch up to ~12 days (1-in-20 extended dry spell, power cost: ~14 USD)
High Variance Alert: In a 1-in-20 severe drought (~12 days), cumulative electricity burned (~14 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.
BlackMiner F2 Price & Estimated ROI
Current market price: $150–$220 (estimated market price, median $185) (Hardware price estimated).
How other hardware compares on Kadena
Devices in the same hashrate class, solo mining Kadena at today's difficulty:
| Hardware | Hashrate | Expected block | Chance in 1 year |
|---|---|---|---|
| Bitmain Antminer KA3 | 166.15 TH/s | 2.4 min | 100.00% |
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 BlackMiner F2 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:

How the odds are calculated
Because each hash succeeds independently, finding a block is a Poisson process — there is no 'due' block, only an average rate. The mean time between blocks is T = network_hashrate ÷ your_hashrate × block_time, and the realistic chance of at least one block over a period t is P = 1 − e^(−t/T). That is why a longer run raises your odds but never guarantees a block. For this pair: daily chance 21.36%, yearly chance 100.00%.
Frequently Asked Questions: BlackMiner F2 on Kadena
Can you solo mine Kadena with a BlackMiner F2?
Yes — a BlackMiner F2 (67.74 GH/s) can solo mine Kadena (KDA) via a solo pool. At Kadena's 16.24 PH/s Kadena network that is about 88 blocks per year — expected one block roughly every 4 days, 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 BlackMiner F2 stand?
Kadena is an ASIC-resistant GPU algorithm relying on memory bandwidth. The BlackMiner F2 ranks #2 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 BlackMiner F2 on Kadena?
At 682 W, operating a BlackMiner F2 consumes 16.37 kWh/day (498.2 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 1.13 USD/day (34.38 USD/month). The operational breakeven threshold is 0.000 USD/kWh.
What happens if my BlackMiner F2 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 12 days, accumulating roughly 14 USD in power costs.
