Product Details

Bitmain Antminer KA3 166TH Base Kadena (KDA) Blockchain Mining ASIC

Standard bin of the most powerful Kadena ASIC ever made. The KA3 at 166 TH/s runs below the top bin at 173 TH/s from row 147. Same 80 dB. Similar power. Same chassis. Different chip quality determines the 7 TH/s gap. 166 TH/s still dwarfs everything else in Kadena mining. Goldshell KD Max: 40.2 TH/s. iBeLink BM-K3: 70 TH/s. Bitmain produces 2.4 to 4.1 times more KDA than the nearest competitors at similar power draw. The KA3 at either bin is the Kadena mining market. 3,154W on 200 to 240V. No 110V. 80 dB louder than standard industrial. Daily electricity at $0.07 per kWh: $5.30. Monthly: $159. Bitmain Antminer firmware. Ethereum connectivity. Kadena runs 20 parallel PoW chains for enterprise throughput. The KA3 secures all 20 simultaneously. Research KDA token value, Pact smart contract adoption, and enterprise use case development before committing capital to dedicated Kadena mining at this scale. 195 x 290 x 430mm at 16.1 kg. 200-240V input. Ethernet. 5 - 40 °C. Bitmain firmware. Daily electricity $5.3 at $0.07 per kWh. Monthly: $159. Compare against Kadena revenue at 166 TH/s. Purchase the Antminer KA3 when the math works: 166 TH/s of Kadena mining revenue minus $5.3 daily electricity times deployment period exceeds hardware cost. Run the numbers with current Kadena data. Kadena mining profitability depends on KDA token price and network difficulty. The multi chain architecture targets enterprise use cases that single chain blockchains cannot serve. Research KDA exchange liquidity and Pact smart contract adoption before committing mining capital.
