Bitmain Antminer A3 on ScPrime — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a Bitmain Antminer A3 on ScPrime (SCP) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine ScPrime with a Bitmain Antminer A3?

Yes — a Bitmain Antminer A3 (812.55 GH/s) can solo mine ScPrime (SCP) via a solo pool. At ScPrime's 1.86 PH/s Sia network that is about 24 blocks per year — expected one block roughly every 15 days, for the full 45.0000 SCP 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 ScPrime

The Bitmain Antminer A3 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 ScPrime, it ranks #1 in electrical efficiency (625,042,307.69 H/W) and #1 in raw hashrate (812.55 GH/s).

Electricity Operating Costs & Breakeven

Running a Bitmain Antminer A3 (1,300 W) pulls about 31.20 kWh per day (949.7 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 2.15 USD per day (65.53 USD/month or 786 USD/year). Statistically that year returns 24.35 blocks, worth about $14.34 — you would burn roughly 55x more in electricity than that reward is worth.

The operational breakeven threshold is 0.001 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): -1.21 USD / day
• At 0.069 USD/kWh (Standard Industrial): -2.11 USD / day
• At 0.120 USD/kWh (Residential Grid): -3.70 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, ScPrime must trade at or above 0.7177 USD at standard industrial power (0.069 USD/kWh), or 1.25 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 15 days, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~18.5 hours (1-in-20 fastest discovery, power cost: ~2 USD)
• Median expectation (50% Odds): Block within ~10 days (Nominal median, power cost: ~22 USD)
• Bad luck streak (5% Odds): Can stretch up to ~45 days (1-in-20 extended dry spell, power cost: ~97 USD)

High Variance Alert: In a 1-in-20 severe drought (~45 days), cumulative electricity burned (~97 USD) will exceed the block reward value (1 USD). Pool mining is recommended for risk-averse operators.

How other hardware compares on ScPrime

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

How the odds have moved

ScPrime's network hashrate fell 47% since 2026-09-22, from 3.52 PH/s to 1.86 PH/s — so the same rig is now 47% more likely to find a block.

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 6.45%, yearly chance 100.00%.

Frequently Asked Questions: Bitmain Antminer A3 on ScPrime

Can you solo mine ScPrime with a Bitmain Antminer A3?

Yes — a Bitmain Antminer A3 (812.55 GH/s) can solo mine ScPrime (SCP) via a solo pool. At ScPrime's 1.86 PH/s Sia network that is about 24 blocks per year — expected one block roughly every 15 days, for the full 45.0000 SCP block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is Sia ASIC-resistant, and where does the Bitmain Antminer A3 stand?

Sia is an ASIC-dominated algorithm. The Bitmain Antminer A3 delivers 812.55 GH/s (#1 of 2 models on ScPrime). 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 A3 on ScPrime?

At 1,300 W, operating a Bitmain Antminer A3 consumes 31.20 kWh/day (949.7 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 2.15 USD/day (65.53 USD/month). The operational breakeven threshold is 0.001 USD/kWh.

What happens if my Bitmain Antminer A3 encounters a severe dry spell on ScPrime?

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 45 days, accumulating roughly 97 USD in power costs.
