Bitmain Antminer HS3 (9TH)

9 TH/s Handshake (Blake2B+SHA3 algorithm) at 2,079W and 231.22 J/TH efficiency (also expressed as 0.231 J/GH). ±3 percent hashrate and ±10 percent power tolerance. Released December 2022 by Bitmain. Highest output Handshake miner in production. MM's spec sheet lists 2,081W; actual Bitmain specification is 2,079W per every distributor worldwide. The 2W difference is minor but the correct figure is 2,079W.

Not at standard electricity rates as of April 2026. MM's own calculator at $0.08 per kWh shows -$0.93 daily loss. At $0.07 per kWh: approximately -$0.43 daily. Break even electricity rate is approximately $0.063 per kWh. Positive margin requires: electricity below $0.05 per kWh (typically industrial or hosted rates), OR meaningful HNS token price appreciation. At $0.04 per kWh industrial rate: +$1.06 daily profit. The HS3 is not an operational profit miner at current market conditions. It is a speculative HNS accumulation tool. Buyers who do not have industrial electricity rates or a strong thesis on HNS price appreciation will lose money on daily operations.

Speculative Handshake (HNS) token accumulation during the protocol's low adoption phase. The thesis: accumulate HNS tokens cheaply through mining while HNS price is low, speculating on meaningful price appreciation if decentralized DNS gains meaningful adoption. This is a long duration, speculative position. HNS is not guaranteed to appreciate. The technology is sound and the developer community is dedicated, but real world adoption remains limited. If you have strong conviction on decentralized DNS gaining traction and access to cheap electricity, the HS3 is the hashrate leader for HNS accumulation. If you need operational daily profit, look elsewhere.

Handshake is a blockchain protocol launched in 2020 for decentralizing DNS and the internet's root zone. The protocol replaces ICANN and root server authorities with on chain domain name registration. Technical architecture is sound. Developer community is dedicated. Real world adoption remains limited because browser integration requires resolver software, creating user experience friction. HNS token price has ranged approximately $0.005 to $0.05 over the past two years. The protocol is in a speculative, early adoption phase rather than mainstream use.

The HS3 dominates the Handshake mining market by hashrate. Bitmain HS3: 9 TH/s, 2,079W. Goldshell HS6: 4.3 TH/s (the second highest HNS hashrate). Goldshell HS6 SE: 3.7 TH/s. Goldshell HS5: 2.7 TH/s. Goldshell HS3 (confusingly same name as Bitmain's product): 2 TH/s. Goldshell HS3 SE: 930 GH/s. Goldshell HS Lite: 1.36 TH/s. Goldshell HS Box II: 460 GH/s (home tier). The Bitmain HS3 produces approximately 2.1 times the hashrate of the highest Goldshell competitor (HS6) and 20 times the output of the entry tier Goldshell HS Box II. For operators committed to HNS accumulation, the HS3 is the highest hashrate per unit.

Potentially. Siacoin (SC) uses the Blake2B algorithm which is similar but not identical to Handshake's Blake2B+SHA3. Some distributor sources reference Siacoin compatibility as a secondary option for the HS3. Verification of firmware support for Siacoin mining on HS3 hardware should be done through MillionMiner or Bitmain support before committing to a Siacoin mining deployment. For most operators, HNS is the primary and only meaningful coin for HS3 deployment.

200 to 240V single phase AC. MM spec sheet correctly lists 200-240V. MM body copy incorrectly claims "universal 100 to 240V" — this contradicts the spec sheet and every distributor source. At 2,079W on 200V draws approximately 10.4 amps (fits standard 15A circuit). At 240V draws approximately 8.7 amps (fits standard 15A circuit). No 110V support. Common commercial and industrial 220-240V service works directly.

75 dB from 4 cooling fans. Standard industrial ASIC noise comparable to Bitmain's S21 series Bitcoin miners. Not suitable for residential or office environments. Requires dedicated mining space: warehouse, container, isolated room, or professional hosting. Alternatively, immersion cooling deployment in dielectric fluid tank can reduce operational noise (though immersion adds infrastructure cost). Plan heat exhaust for 2,079W thermal output.

0 to 40 degrees Celsius per Bitmain's official specification and multiple distributors (BT-Miners, CryptoMinerBros). MM's spec sheet lists 5 to 45°C which is broader than Bitmain's documented range. Storage temperature: -20 to 70°C. Operating humidity: 10 to 90 percent. Altitude ≤2000 meters with 1°C maximum temperature reduction per 300m above 900m altitude.

430 x 195 x 290 mm at 16.1 kg. Standard Bitmain Antminer chassis dimensions comparable to the S21 series. Rack mountable. Single technician installable. Bitcoin Merch's listing of "6,100 g" (6.1 kg) and "331 x 234 x 391 mm" appears to be data entry errors — every other distributor confirms 16.1 kg at 430 x 195 x 290 mm.

The HS3 produces 231.22 joules per terahash of Handshake work. Expressed alternately as 0.231 J/GH (gigahash). This is not competitive with modern Bitcoin mining efficiency (10-15 J/TH on SHA-256) but Handshake's low network hashrate means per unit HNS production per watt is reasonable at industrial electricity rates. The efficiency is adequate for the niche; it is not the limiting factor in HS3 economics. The limiting factor is HNS token price and network difficulty.

All major Handshake mining pools. F2Pool, 6Block, NiceHash (Handshake support), Handshake's own pools, and other HNS-compatible pools. Standard Stratum protocol with Handshake-specific extensions. Bitmain's firmware is stable and widely compatible across the HNS pool ecosystem.

Yes. Bitmain's APW11 or equivalent PSU accepting 200-240V. Standard AC power cable included. No external PSU to source separately. Connect directly to appropriate 200-240V outlet (verify circuit amperage: 15A minimum recommended for reliable operation).

6 month Bitmain manufacturer warranty, confirmed by BT-Miners and MM's other product listing on millionminer.com. Standard for Bitmain's non-flagship products. Covers manufacturing defects and hardware failures under normal operating conditions. Warranty begins from shipping confirmation date. Tampering with warranty label or improper voltage input voids warranty per standard Bitmain terms.

Standard Bitmain Antminer setup. Connect PSU to 200-240V outlet (verify circuit amperage: 15A minimum). Connect Ethernet cable to router or switch. Find miner IP through Bitmain IP Reporter, router DHCP, or network scanning. Open Antminer web interface, configure Handshake pool URL and HNS wallet address. Verify hashrate stabilizes at approximately 9 TH/s within 5-10 minutes. Monitor via web dashboard or standard Bitmain management tools.

Yes. MillionMiner hosting facilities accept Handshake mining hardware. At hosted rates of $0.05-$0.07 per kWh: HS3 operates at break even to slight negative daily margin. At $0.04 per kWh industrial hosted: +$1.06 daily. Hosting eliminates facility noise, cooling, and 220V infrastructure requirements. For buyers who want to speculate on HNS without managing infrastructure, hosted HS3 deployment is the cleanest option.

Depends entirely on your HNS accumulation thesis strength and electricity cost. One HS3 at 2,079W produces approximately 18 HNS per day at current network difficulty (approximately 540 HNS per month, 6,570 HNS per year). If you believe HNS will reach $1 per token at some future date, one HS3 accumulating 6,570 HNS per year produces a potential portfolio value of $6,570 annually (assuming token appreciation). Scale deployment to your conviction level and electrical capacity. At 2,079W per unit, a dedicated 15A 240V circuit supports one HS3. A 20A 240V circuit supports up to 2 units.

Standard air cooled Antminer maintenance. Quarterly dust cleaning of 4 fans and intake. Annual fan bearing inspection (fans rated for standard industrial lifespan). Monitor hashrate through Bitmain web interface. Released December 2022, the HS3 has 3+ years of field reliability data as of April 2026. No known systemic reliability issues.

The HS3 is a specific use case product. Buy if: you have strong conviction on Handshake protocol adoption and want the highest hashrate per unit for HNS accumulation, you have industrial electricity below $0.04 per kWh for operational profitability, you are comfortable with speculative cryptocurrency hardware at current negative daily margin conditions, or you are an existing HNS ecosystem participant wanting to support network security. Do not buy if: you need daily operational profit (HS3 loses money at $0.08/kWh residential rates), you need liquid exit markets (HNS has thin trading liquidity on limited exchanges), you are new to cryptocurrency mining (speculative altcoin hardware is not a beginner's position), or you are uncertain about HNS token long term value (the buying thesis depends entirely on HNS appreciation).
