On September 19th, official sources announced that Hut 8, a North American Bitcoin mining company, has partnered with Bitmain, a digital currency mining server manufacturer, to launch a new generation of ASIC miners, the U3S21EXPH. The miner boasts a performance of 860 TH/s with an energy efficiency ratio of 13 J/TH.

Hut 8 plans to deploy these miners through a hosting agreement of approximately 15 EH/s in the second quarter of 2025, with the option to transition to self-mining through a purchase option. This collaboration will aid Hut 8 in expanding its hashrate capacity, increasing hosted hashrate from 18.5 EH/s to approximately 33.5 EH/s.
