Company Overview

SHI currently conducts our business through our wholly-owned subsidiary, SCI. SCI is engaged in the mining of cryptocurrency through data centers that can be powered by renewable energy sources. Recently, SCI has built, and intends to continue to develop and build, modular data centers that are currently used for cryptocurrency mining and that in the future can be used for computing intensive, batchable applications, such as artificial intelligence and machine learning, with the goal of providing a cost-effective alternative to battery storage or transmission lines.
