This is a reverse private auction GoldShell CK5 12Th CKB Nervos ASIC Miner for Eaglesong has already finished

The Goldshell CK5 is a dedicated miner for the Eaglesong algorithm powering Nervos Network's CKB, delivering up to 12 TH/s at 2400 W with about 200 J/TH efficiency. It uses air cooling with two high-speed fans for heat management, though it runs at 80 dB, so it is best in a dedicated mining space. Dimensions are 264 x 200 x 290 mm, weight 8.5 kg, and it operates on 220 V with Ethernet in a 5-35 C range and 5-95% humidity. Launched in March 2021, the CK5 remains a solid, high performance option for CKB mining.
