Sazmining announced Thursday that individual and institutional buyers can now purchase Proto immersion hashboards through Sazmining's mining-as-a-service platform. Each hashboard delivers roughly 200 TH at around 15 J/TH. Buyers own the hardware outright, while Sazmining handles deployment, monitoring and maintenance at a US facility. Mining rewards go directly to the owner's wallet. The launch follows a multi-megawatt supply deal with Proto, the bitcoin mining arm of Jack Dorsey's Block.
