TeraWulf, the bitcoin mining company, has agreed to purchase 30,000 mining machines from Bitmain. In its official blog post, Bitmain said Tera Wulf will buy Bitmain’s latest generation of miners dubbed the Antminer S19j Pro, which will be delivered from January to June 2022. TeraWulf is expected to increase its total mining hash rate by 3 exahashes per second, which means the machines will be able to compute an extra 3 quintillion calculations per second.
