Eaglesong is Nervos Network's proof-of-work algorithm, and the K7 is the machine most CKB miners run: 63.5 TH/s at 3080W, 48.5 J/TH. It replaced Bitmain's much slower K5 and dwarfs it on output. Cooling is air, four fans, standard Bitmain chassis, 220-240V input. At this price it is one of the cheapest routes into a dedicated altcoin ASIC, though the price is telling. CKB block rewards step down on the network's own halving schedule and difficulty has climbed a long way since the K7 launched in 2023, so run current numbers rather than launch-era ones. It suits a miner with cheap power who wants to accumulate CKB over time. As with any single-algorithm ASIC, revenue tracks one coin and nothing else.
Key Features

Efficiency king in my farm
Among all the miners in my farm, the Antminer K7 is the efficiency king. Best J/TH ratio and it shows in my monthly electricity bills. Smart engineering by the manufacturer.
Sets new standard in my operation
The Antminer K7 sets a new standard in my operation. Everything else now feels outdated by comparison. This is the future of mining efficiency.
Scaled from 1 to 3 containers in a year
Started with one Antminer K7 last year and we're now running three. The modularity is the real selling point — each container is its own self-contained data center. Our total hash rate tripled without any of the headaches of traditional facility expansion.
Best buying experience
Buying my Antminer K7 from MinerHaolan was the best purchasing experience I've had for mining equipment. From inquiry to delivery, everything was smooth and professional.
