Proto Rig (819TH)

The Proto Rig produces 819 TH/s of SHA-256 hashrate at 12,000W continuous power draw. Efficiency rates at 14.65 J/TH per MillionMiner and several distributors, or 14.1 J/TH per Proto's official manufacturer specification reflecting optimal operating conditions and higher quality chip binning. Output comes from nine individually removable hashboards, each contributing approximately 91 TH/s. Real world efficiency typically falls within this range depending on batch, operating environment, and firmware tuning. Proto rates the unit at plus or minus 5 percent hashrate tolerance.

Proto, the mining hardware division of Block Inc. (Jack Dorsey's public company, formerly known as Square). This matters for several reasons: Block is a US publicly traded company with billions in market capitalization, demonstrated multi year commitment to Bitcoin infrastructure, regulatory compliance exceeding typical Chinese ASIC manufacturers, and long term product support capacity beyond what opaque manufacturers can provide. Russell Cann, Chief Development Officer at Core Scientific (one of the largest publicly traded Bitcoin mining companies), publicly endorsed the Proto Rig as infrastructure grade hardware.

Three concrete advantages over traditional sealed ASIC miners. First: partial failure resilience. When one hashboard fails, the remaining eight continue mining without interruption. You lose 91 TH/s (11 percent of capacity) rather than the entire 819 TH/s machine during repair cycles. Second: field repairs in minutes. Hot swap hashboards on the rack in under 90 seconds without tools or system shutdown, versus shipping traditional ASICs back to manufacturers for warranty repair. Third: incremental upgrades. When Proto releases next generation hashboards with improved efficiency or higher hashrate, upgrade by swapping boards into the existing chassis rather than purchasing entirely new miners.

Traditional Bitcoin ASICs face replacement cycles every 3 to 5 years as newer chip generations render older hardware uncompetitive on efficiency. The entire sealed unit becomes electronic waste and replacement capital expense. The Proto Rig chassis targets 10+ year lifespan through incremental hashboard upgrades. Per Proto's analysis and independent reviews including CryptoMinerBros and Mineshop EU, upgrade costs run approximately 15 to 20 percent lower per generation compared to full machine replacement. Over a 10 year facility operational horizon, this compounds into substantial capital cost savings. For industrial operators, the math favors modular architecture if upgrade cycles materialize as expected.

Several meaningful differences versus traditional ASICs. Only 6 cooling fans cool the full 819 TH/s output, compared to 21 fans on the leading competitor machine of similar footprint — fewer parts, fewer failure points, lower maintenance overhead. Three 4,000W PSUs rated fanless with thermal design relying on system airflow (no PSU fan failures). 9.4 kW per foot power density allows three Proto Rig units in the physical space typically occupied by two traditional competing machines. Dual air and immersion compatibility: the same chassis deploys in air cooled facilities with fans pre-installed, or converts to immersion cooling by removing fans before tank deployment. This eliminates typical either/or infrastructure commitment between cooling architectures.

Proto Fleet is the open source mining management software accompanying the hardware. Unlike proprietary management tools from Bitmain (Antminer firmware) or MicroBT (Whatsminer firmware) that lock operators into vendor specific workflows, Proto Fleet publishes source code under open license with open APIs for custom integration into existing monitoring infrastructure. For large scale operators running heterogeneous fleets, wanting deep custom automation, or needing programmatic integration with facility management systems, open source management is a meaningful differentiator. No licensing fees, no training requirements, full operator ownership of the management stack.

Electricity rate dependent. MillionMiner's $0.08 per kWh onsite calculator shows $26.66 daily revenue, $23.04 electricity, $3.62 net profit per day. OneMiners April to August 2025 data at $0.04 per kWh industrial rates: $25 to $35 daily earnings averaging $29.04, with ROI estimates 8 to 14 months. Mining Now current data shows $26.42 daily Bitcoin revenue. Economic viability requires industrial electricity below $0.07 per kWh for reliably positive margins at current Bitcoin network difficulty. At $0.04 per kWh negotiated industrial rates, margins are strong. At residential rates above $0.10 per kWh, the Proto Rig runs at loss.

208 to 240V single phase through three 4,000W PSUs. At 240V single phase: approximately 50 amps continuous draw across all three PSUs at 12,000W total. Dedicated 60 amp circuit minimum. For three phase 208V deployments with appropriate PSU configuration, total draw distributes across phases. Suitable for commercial industrial facilities with proper electrical infrastructure. Not compatible with residential electrical systems without significant service upgrades. Industrial facility deployment is the design target.

Yes. The Proto Rig chassis is specifically designed for dual air and immersion compatibility. For air cooled deployment: fans ship pre-installed and the unit operates in standard server rack environments with ventilation. For immersion deployment: remove the fans before submerging the chassis in dielectric fluid tanks. This flexibility eliminates typical either/or infrastructure commitment between cooling architectures. Operators can deploy initially in air cooled facilities and convert to immersion later as tank infrastructure matures, or vice versa.

80 dB operating noise, louder than the 75 dB standard for typical industrial ASIC miners. The additional noise reflects the airflow requirements for cooling near petahash SHA-256 output in a compact chassis. Not suitable for residential living spaces or environments with human presence for extended periods without hearing protection. Appropriate deployment locations: dedicated industrial mining rooms, warehouse facilities with proper acoustic isolation, shipping container deployments, and professional hosting facilities. Standard industrial hearing protection recommended when working near the hardware.

No. The 12,000W power draw exceeds residential electrical capacity in most homes. Dedicated 60 amp circuits at 240V single phase represent major electrical infrastructure upgrades. The 80 dB operating noise is unsuitable for residential environments. The 50 kg weight requires industrial grade racking. Proto Rig is specifically designed for industrial scale mining operations, commercial facilities, and professional hosting deployments. Home operators considering high hashrate deployment should look at Antminer S21 XP at 270 TH/s or Whatsminer M70S+ at 244 TH/s on single phase 240V residential circuits instead.

Different architecture, different positioning. Proto Rig: 819 TH/s at 12,000W and 14.65 J/TH in air cooled modular chassis with hot swappable hashboards, 10+ year chassis lifespan target. Antminer S23 Hyd 3U: 1,160 TH/s at 11,020W and 9.5 J/TH in sealed hydro cooled 3U rack mount. The S23 Hyd leads on absolute hashrate per unit and efficiency per terahash, reflecting newer chip silicon. The Proto Rig leads on modularity, reparability, and long term chassis economics. For operators building dedicated hydro infrastructure and maximum efficiency, the S23 Hyd is the technical winner. For operators prioritizing infrastructure longevity and serviceability, the Proto Rig offers a fundamentally different product philosophy.

A 100 kW electrical panel supports approximately 8 Proto Rig units at 12,000W each, producing 6,552 TH/s aggregate hashrate. Compare against 7 Antminer S23 Hyd 3U units per 100 kW panel producing 8,120 TH/s (higher total hashrate through better efficiency), or 14 M78S immersion units producing 6,608 TH/s (similar total at different power tier). Proto Rig fleet positioning is not about maximum hashrate density but about infrastructure longevity and modular flexibility over multi year deployment horizons.

Industrial deployment with 240V single phase power. Step one: install dedicated 60 amp circuit at 208 to 240V. Step two: ensure adequate ventilation or immersion tank capacity for 12,000W thermal load. Step three: rack mount or tank position the Proto Rig. Step four: connect three PSU power cables to electrical service. Step five: connect Ethernet cable to facility network. Step six: power on, find miner IP through DHCP, configure Bitcoin mining pool URL and wallet address through Proto Fleet management interface or direct web interface, verify aggregate hashrate reaches 780+ TH/s within 15 to 20 minutes.

Proactive maintenance benefits significantly from the modular design. Monthly fan cleaning (only 6 fans versus 21 on competitors, simplifying this task). Quarterly hashboard visual inspection (hashboards individually accessible without disassembling the full unit). Individual hashboard replacement takes under 90 seconds tool free when failures occur. Firmware updates handle centrally through Proto Fleet. The open source firmware enables community developed maintenance tools and custom monitoring integration. Budget 3 to 5 percent of acquisition cost annually for replacement parts, with individual hashboards as the primary replacement item over multi year operation.

Proto manufacturer warranty on the complete system covering manufacturing defects and hardware failures under normal operation within specified environmental ranges. The modular architecture means hashboard level warranty coverage applies even after potential chassis warranty expiration. Warranty exclusions include damage from inadequate cooling, operation outside environmental ranges, power surge damage from inadequate electrical protection, and unauthorized hardware modifications. MillionMiner routes warranty claims through direct Proto channels. Block's involvement as a US public company suggests stronger long term warranty support than typical opaque Chinese ASIC manufacturers.

Yes. MillionMiner operates managed hosting facilities with appropriate electrical service and ventilation infrastructure capable of supporting Proto Rig deployments, including both air cooled and immersion hosting options. Hosted deployment eliminates facility infrastructure CapEx for operators preferring turnkey deployment. Professional hosting at negotiated industrial rates significantly improves Bitcoin mining margins. Contact MillionMiner sales through the Get a Quote button for hosting pricing, capacity availability, and deployment timelines.

Acquisition cost plus infrastructure and operations. MillionMiner price aligns with market range around $8,400 to $10,000 per unit. Additional CapEx for self hosting: industrial electrical service ($5,000 to $20,000 per facility), ventilation or immersion infrastructure ($5,000 to $20,000 per rack depending on cooling choice), racks and cabling. Annual OpEx per unit at 12 kW continuous: electricity at $8,410 at $0.08 per kWh, $7,360 at $0.07 per kWh, or $4,205 at $0.04 per kWh industrial rates. Modular upgrade costs approximately 15 to 20 percent lower per generation compared to full machine replacement at traditional ASIC fleet refresh cycles. Over 10 year horizon, modular economics favor the Proto Rig for operators committing to long term facility operation.

Proto Rig represents infrastructure grade hardware philosophy applied to Bitcoin mining for the first time. Traditional ASIC miners are designed as disposable 3 to 5 year consumer products scaled to industrial deployment. The Proto Rig applies principles from enterprise computing infrastructure: modular components, hot swap capability, field serviceability, open source management, and multi decade operational targets. If the platform succeeds at 10+ year chassis lifespans with continuous hashboard upgrades, it fundamentally changes the capital structure of Bitcoin mining operations. Traditional ASIC fleet refresh cycles become hashboard upgrade cycles with dramatically lower capital requirements per generation. For operators building durable infrastructure rather than managing disposable hardware, the Proto Rig offers a fundamentally different product philosophy.

For comparison at similar hashrate class: Antminer S23 Hyd 3U at 1,160 TH/s (higher hashrate, sealed hydro architecture, different ecosystem). For lower power tier deployment alongside Proto Rig units: Antminer S21 XP at 270 TH/s or Whatsminer M70S+ at 244 TH/s serve smaller deployments within the same facility. For immersion cooling facilities where Proto Rig deploys in tanks: Whatsminer M76S+ at 390 to 440 TH/s represents MicroBT's immersion tier for mixed fleet deployment. Cross algorithm diversification options include Antminer KS7 for Kaspa, Antminer L11 for Litecoin and Dogecoin, Antminer Z15 for Zcash. For multi vendor Bitcoin mining fleets wanting diversified hardware exposure, the Proto Rig represents Block's modular architecture alongside Bitmain Antminer series and MicroBT Whatsminer hardware. MillionMiner's ASIC hosting service accepts Proto Rig units at negotiated industrial electricity rates.
