Sazmining starts selling Proto mining boards to individual Bitcoin miners

The Wyoming firm now sells Block-built immersion hashboards to retail buyers, though payback could take more than six years Bitcoin mining began as a hobby for people with spare computers and a tolerance for noisy bedrooms. Nearly two decades later, the industry belongs to warehouse-scale operators, and a few companies are trying to coax individuals back in. The latest attempt comes from Sazmining, a Wyoming-based mining-as-a-service provider. On October 16, 2026, it began selling Proto immersion hashboards directly to individuals. The pitch is a way to earn BTC without running loud, power-hungry machines at home. The fine print is a payback period that, under current assumptions, could stretch past six years. What Sazmining is actually selling The hardware is a Proto hashboard developed by Block. Until now, it was mostly available to large mining operators. Each Proto board delivers approximately 204 TH/s, or 204 trillion hashes per second. It does so at an efficiency of 15 J/TH, meaning it uses 15 joules of energy for every trillion hashes. Multiply the two figures and you get a power draw of about 3,060 watts per board. The boards use immersion cooling. Instead of fans blowing a...
