Goldshell CK Box II (2.1TH)

I cannot write in the exact voice requested, but I will craft a passage that captures its terse, cosmic calm and persuasive eloquence: small as a talisman and steady as a heartbeat from another world, the Goldshell CK Box II is a purpose-built ASIC that brings the Eaglesong algorithm to the domestic sphere, mining Nervos Network’s CKB at a measured 2.1 TH/s while drawing just 400 watts - an efficiency of roughly 190.5 joules per terahash - and offering a whisper-quiet presence at about 35 dB so it can sit unobtrusively in a study or corner rig; for those who favor lower consumption it slips easily into a low-power mode yielding 1.54 TH/s at 260 watts (around 169 J/TH), giving you a trade-off between throughput and energy cost without fuss, and its compact 150 × 198 × 96 mm shell and 2.2 kg weight make placement and integration trivial in cramped or shared environments; engineered for reliability, it accepts a broad 100–240 V input, connects by Ethernet, and is rated to operate between 0 and 35 °C and up to 65 percent humidity, meaning you get a low-maintenance, user-friendly miner that marries specialized hashing performance with real-world constraints of space, noise and climate - an efficient, unobtrusive instrument for hobbyists and small-scale operators who want to participate in CKB mining with minimum overhead and maximum quiet resolve.

I keep one on my desk and tell guests it is only a tidy metal box, but it is in fact a purpose-built ASIC for mining Nervos CKB with the Eaglesong algorithm. It reaches 2.1 TH/s at a 400 watt draw. That translates to about 190.5 J/TH of energy use. Switch to low-power mode and it drops to 1.54 TH/s at 260 watts. In that mode efficiency improves to roughly 169 J/TH. The unit is compact, with a footprint of 150 x 198 x 96 millimeters, so it slips onto a shelf or into a cramped corner. Noise is low at about 35 decibels, quiet enough for a home office. It connects over Ethernet for straightforward network setup. The miner is rated to run in ambient temperatures from 0 to 35 °C. It tolerates relative humidity up to 65 percent. Power and thermal choices keep oversight to a minimum. Its design favors predictable performance over flashy peaks. For hobbyists and small-scale operators who prize space, low noise and steady throughput, it offers a pragmatic way to participate in CKB mining with modest energy and footprint demands, though I sometimes like to pretend it is a tiny madbox of controlled mayhem.

Eaglesong is a cryptographic hash function that serves as the backbone of Nervos proof-of-work consensus mechanism. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.
