Sazmining said Thursday that individual and institutional buyers can purchase Proto immersion hashboards through its mining-as-a-service platform. According to NS3.AI, each unit delivers roughly 200 TH at around 15 J/TH, and buyers own the hardware outright. Sazmining will deploy, monitor and maintain the equipment at a U.S. facility, while mining rewards go directly to each owner's wallet. The launch follows a multi-megawatt supply deal with Proto, Block's bitcoin mining arm.
