CleanSpark (CLSK), a U.S.-based bitcoin BTC$106,199.49 mining firm, said Tuesday that it reached 50 exahashes per second (EH/s) of operational hashrate — a milestone that makes it one of the largest mining operations in the world.The company built and operates more than 30 sites across Georgia, Mississippi, Tennessee and Wyoming. A vertically integrated setup gives CleanSpark control over energy procurement and operations, helping reduce costs and boost uptime. “It reflects years of focused strategy, disciplined execution, and a relentless commitment to doing things the right way,” said CEO Zach Bradford. Hashrate is a metric used to measure the computing power behind the Bitcoin network. The higher a given company’s hashrate, the higher its chances of earning bitcoin rewards. The firm is now preparing to scale up to 60 EH/s, with Bradford stating the company was in “escape velocity” mode. Meanwhile, CleanSpark’s Digital Asset Management arm has begun actively managing over 12,500 self-mined bitcoin to generate returns and support expansion without issuing new shares. “We’re mining bitcoin efficiently, holding it responsibly, and putting it to work in ways that drive shareholder value,” Bradford said.
