Goldshell HS3 (2TH)

The HS3 is a dual algorithm miner with distinct outputs per mode. Handshake (HNS) mode: 2 TH/s at 2,000W power draw and 1.0 J/GH efficiency. Blake2B-Sia (Siacoin SC) mode: 4 TH/s at 2,000W power draw and 0.5 J/GH efficiency. The Siacoin mode delivers twice the hashrate at the same power draw, reflecting the different computational characteristics of the two algorithms. Real world output typically falls within plus or minus 5 percent of rated hashrate depending on ambient temperature and firmware tuning.

No, and notably so. ASIC Miner Value calculates negative $4.56 daily profit even at $0.00 per kWh free electricity. This means at current HNS and SC token prices with current network difficulty, the HS3 produces less mining revenue than zero per day. The hardware cannot mine profitably under any electricity cost scenario at present market conditions. MillionMiner's $0.08 per kWh calculator shows negative $2.98 daily, Minerstat pool data across ViaBTC HNS, DXPool HNS, DXPool SC shows negative $4.09 to $4.19 daily at $0.10 per kWh. No pool and no electricity rate currently produces positive margins on the HS3.

Three specific scenarios justify acquisition despite current negative economics. First: speculative positioning on significant HNS or SC token price appreciation from current depressed levels, where operators view mining as accumulation strategy willing to absorb negative carry for years in exchange for potential 5x to 10x token appreciation. Second: Handshake or Sia protocol ideological supporters willing to subsidize network hashrate for decentralization reasons without profitable mining expectation. Third: Goldshell ecosystem collectors or operators with existing Goldshell fleet infrastructure wanting to expand legacy deployments. For operators seeking currently profitable mining hardware as primary objective, the HS3 is not the right choice.

Handshake (HNS) is a decentralized naming protocol designed as an alternative to the existing ICANN DNS root zone. The protocol aims to decentralize internet naming infrastructure by replacing centralized domain authority with distributed consensus. HNS tokens function as the native asset for domain registration on the Handshake blockchain. Launched 2020, practical adoption has remained niche through 2026 with limited decentralized DNS use cases materializing at scale. HNS token prices have traded at depressed levels reflecting the adoption challenge. The network remains operational with active developer community but has not achieved the broad adoption that would support substantial HNS token appreciation or meaningful mining economics.

Substantially outclassed by newer options. Goldshell HS5 (Feb 2021): 2.7 TH/s HNS at 2,650W (35 percent more HNS hashrate for 32 percent more power). Goldshell HS6 SE: 3.7 TH/s HNS. Goldshell HS6: 4.3 TH/s HNS at 3,250W (115 percent more HNS hashrate). Bitmain Antminer HS3: 9 TH/s HNS at approximately 2,000W (same power as Goldshell HS3, 4.5x more HNS hashrate, significantly better efficiency). For operators specifically targeting Handshake mining as current economic activity rather than speculative positioning, newer hardware options provide better per unit economics. The Goldshell HS3 positions as legacy inventory at potentially meaningful discount versus newer alternatives.

Important clarification. Bitmain's Antminer HS3 is an entirely separate product from a different manufacturer (Bitmain, not Goldshell), despite the coincidental "HS3" model name. The Bitmain Antminer HS3 produces 9 TH/s HNS at approximately 2,000W, roughly 4.5 times the Goldshell HS3's HNS hashrate at similar power draw. The naming similarity creates potential buyer confusion: verify manufacturer branding (Bitmain versus Goldshell) when comparing HS3 options. Bitmain's HS3 availability varies by market and distributor channel. The MillionMiner product listed here is specifically the Goldshell HS3.

Through Goldshell firmware web interface. Access the miner's IP in a web browser, navigate to algorithm settings, select target algorithm (Handshake or Blake2B-Sia), update pool configuration for the new algorithm (HNS pool URL for Handshake, SC pool URL for Siacoin), enter appropriate wallet address for the algorithm, save settings and restart. Switch completes in 2 to 5 minutes. No hardware modifications, firmware reflashing, or physical access to the unit required beyond network access. Operators running both algorithms at different times can save multiple configurations for quick switching.

176 to 264V voltage range (wider tolerance than typical modern ASICs). At 2,000W and 240V: approximately 8.3 amps continuous draw. Fits within standard 15 amp commercial breakers. Works on European Schuko (230V), UK BS 1363, Middle Eastern 220 to 240V commercial, North American 240V NEMA 6 outlets, and North American 208V three phase configurations without voltage conversion. Wide voltage range provides deployment flexibility for non standard electrical configurations.

75 dB operating noise, standard industrial ASIC acoustic signature. Comparable to a loud vacuum cleaner at close range. Not suitable for residential living spaces, bedrooms, home offices, or shared environments without sound insulation. Appropriate deployment locations include dedicated mining rooms, garages with ventilation, outbuildings, warehouse facilities, shipping container installations, and professional hosting facilities. For operators wanting quieter Goldshell Handshake hardware for home office deployment, the Goldshell HS3 SE at 55 dB represents the low noise variant in the lineup.

Generally no. The 2,000W power draw is manageable on commercial 240V circuits but challenging on typical residential electrical systems. The 75 dB noise level is unsuitable for residential living spaces. Additionally, the current unprofitability at any electricity rate means home deployment loses money daily even ignoring infrastructure constraints. For operators specifically committed to home Handshake or Siacoin mining on Goldshell hardware, the HS3 SE (1.86 TH/s at 930W and 55 dB) represents the home deployment appropriate alternative, though it also faces current profitability challenges.

Standard Ethernet 10/100M. Initial setup: connect PSU to 176 to 264V outlet, connect Ethernet cable to router or switch, find miner IP through router DHCP client list or IP scanner tool, open Goldshell web interface in browser at the device IP. Goldshell firmware provides algorithm selection, pool URL configuration, wallet address entry, hashrate monitoring, and temperature sensor readings. No WiFi support. Standard plug and play on commercial networks with DHCP.

All major Handshake pools: ViaBTC HNS, DXPool HNS, F2Pool Handshake, 2Miners Handshake. All major Siacoin pools: DXPool SC, MiningRigRentals Blake2b marketplace, Luxor Siacoin. Pool fees typically run 1 to 2 percent. Standard Stratum protocol compatibility with both algorithms. Given current unprofitable mining economics, pool selection primarily affects how much the operator loses per day rather than profit margins.

310 x 180 x 280 mm per MillionMiner specification, or 180 x 280 x 310 mm per Asic Marketplace and BitcoinMerch representing different chassis orientation. 7 kg weight. Two fan air cooling design. Compact industrial form factor allowing stacked deployment in rack configurations. Standard ASIC physical specifications compatible with typical mining facility infrastructure.

Standard Goldshell ASIC setup. Step one: verify 176 to 264V electrical circuit with 15 amp capacity. Step two: ensure adequate ventilation in deployment space for 2,000W thermal load. Step three: connect PSU to outlet and power cables to miner. Step four: connect Ethernet cable to router or switch. Step five: power on, find miner IP through router DHCP list, open Goldshell web interface. Step six: select target algorithm (Handshake or Blake2B-Sia), configure pool URL and wallet address for selected algorithm, save settings. Step seven: verify hashrate reaches target output (1,900+ GH/s HNS or 3,800+ GH/s SC) within 5 to 10 minutes.

Standard air cooled ASIC maintenance with specific considerations for 5+ year old hardware. Monthly fan cleaning with compressed air to clear dust buildup (particularly critical given 2020 era hardware may have accumulated operational hours on secondary market units). Quarterly hashboard connector inspection. Given the October 2020 release date and potential years of prior operation, budget for potentially higher maintenance including fan replacements (both fans replaced at least once per typical multi year deployment), power supply replacements, and occasional hashboard repairs. Goldshell spare parts availability for 2020 era hardware may be limited compared to current generation products. Factor approximately 10 percent of acquisition cost annually for maintenance on legacy hardware.

Goldshell factory warranty terms vary significantly given the October 2020 release date. New old stock inventory from original distribution channels may carry original warranty (typically 180 days from original purchase, now long expired for 2020 era units). Secondary market inventory typically carries limited or no warranty. MillionMiner clarifies warranty coverage per specific batch and inventory source through the Get a Quote process. For legacy hardware purchases, operators should factor potential warranty limitations into acquisition decisions and budget for out of warranty repairs.

Very limited support for 2020 era hardware. Goldshell typically maintains firmware support for current generation hardware with narrower support for legacy models. Critical security patches may receive updates, but new feature development and optimization focuses on current generation products (HS6, KD Max, LT6, KA Box, etc.). For operators dependent on ongoing firmware support as part of acquisition decision, the HS3 likely represents end of life hardware with minimal future firmware updates expected.

Speculative scenario requires specific assumptions. Starting point: current HNS and SC token prices at depressed levels reflecting niche adoption. Thesis: if decentralized DNS (Handshake) or decentralized storage (Siacoin) adoption materializes significantly in coming years, token prices could appreciate 5x to 10x or higher, potentially turning accumulated mining rewards during low price periods into substantial historical value. Math at 10x HNS price appreciation: current $220 annual HNS revenue per unit becomes $2,200 annual equivalent in appreciated terms, against approximately $7,000 multi year accumulated electricity loss at residential rates. Break even at 30x to 50x token appreciation depending on deployment timeline and electricity cost. Not a high probability scenario, but the specific speculative thesis some operators accept.

Acquisition plus operations plus accumulated losses. Original 2020 retail pricing: $3,500 to $6,000 per unit. Current 2026 pricing reflects significant depreciation (verify MillionMiner current pricing). Annual OpEx per unit at 2,000W continuous: $1,402 at $0.08 per kWh, $1,226 at $0.07 per kWh, $701 at $0.04 per kWh industrial rates. Annual revenue at current HNS/SC network data: approximately $220 to $260. Net annual loss: $1,000 to $1,200 at residential rates, $450 to $500 at industrial $0.04 per kWh rates, still negative even at $0.00 per kWh per ASIC Miner Value. Three year cumulative losses exceed $3,000 per unit at residential rates. Speculative acquisition requires willingness to absorb these losses against uncertain future token appreciation.

For currently profitable mining hardware at similar price points: Antminer S21+ at 235 TH/s or Whatsminer M70S+ at 244 TH/s provide economically viable Bitcoin mining with positive daily margins. Antminer KS7 at 45 TH/s for Kaspa (established mid cap token with broader adoption than Handshake). Antminer L11 at 35 GH/s for Litecoin and Dogecoin merged mining (established economics). IceRiver AE3 at 2 GH/s for Aleo (emerging zkSNARK network with strong 2026 profitability data). Within Goldshell lineup: HS6 (4.3 TH/s HNS at 3,250W) for current generation Handshake hardware if committed to this algorithm. For quieter home deployment on Handshake specifically: Goldshell HS3 SE (1.86 TH/s at 930W and 55 dB). MillionMiner's ASIC hosting service accepts legacy hardware at industrial rates for operators committed to Handshake or Siacoin despite current profitability challenges.
