Bitmain Antminer KS7 40TH KHeavyHash Kaspa ASIC Miner with Industry Leading Hashrate

40 TH/s of KHeavyHash hashrate at 3,080W for mining Kaspa (KAS). The Antminer KS7 is Bitmain's dedicated Kaspa ASIC, competing in a market previously dominated by Goldshell and IceRiver. KHeavyHash is a memory hard proof of work algorithm, and Bitmain brings their manufacturing scale and established firmware ecosystem to this network.

77 W/TH efficiency on 220 to 277V single phase. 430 x 196 x 290mm at 16.4 kg with 75 dB air cooling. The form factor and noise level are typical of professional grade Antminers, meaning this is dedicated mining facility hardware. Ethernet connectivity through the standard Bitmain web management interface.

Kaspa uses a blockDAG architecture (GHOSTDAG consensus) that enables extremely fast block times of one second. The network processes transactions in parallel rather than sequentially. Mining Kaspa contributes to this consensus by solving KHeavyHash proofs.

Note that Kaspa has discussed transitioning its mining algorithm in the future. If KAS moves away from KHeavyHash, dedicated KHeavyHash ASICs would no longer be compatible. This is a risk factor for any single algorithm ASIC purchase. Monitor the Kaspa development community for algorithm change timelines. Operates from 5 to 45 degrees Celsius with 10 to 90 percent humidity tolerance.

Bitmain's entry into Kaspa mining signals that KAS has reached sufficient market cap and mining demand to attract the largest ASIC manufacturer. The KS7 brings Antminer level build quality, established supply chains, and proven firmware to a mining ecosystem previously served by smaller manufacturers.

Antminer KS7 40TH KHeavyHash Kaspa ASIC Mining Machine

40 TH/s KHeavyHash at 3,080W for Kaspa (KAS) mining. 77 W/TH efficiency on 220 to 277V. Bitmain's dedicated Kaspa ASIC bringing Antminer build quality and firmware to a market previously led by Goldshell and IceRiver.

75 dB air cooled at 430 x 196 x 290mm and 16.4 kg. Standard Bitmain web management interface on Ethernet. Professional mining facility hardware.

Kaspa uses blockDAG architecture with one second block times. Note the potential for a future algorithm change that would affect KHeavyHash hardware compatibility. Monitor Kaspa development discussions before committing to large orders. 5 to 45 degrees Celsius.

Bitmain entering the Kaspa mining market with the KS7 validates KAS as a mining ecosystem large enough for the biggest ASIC manufacturer. The KS7 brings Antminer supply chains, warranty support, and proven firmware reliability to Kaspa miners who previously relied on smaller manufacturers like Goldshell and IceRiver.
