Note 1.  Organization:

Riot Blockchain, Inc.

Effective October 19, 2017, the Company changed its state of incorporation to Nevada from Colorado.

The Company operates a digital currency mining operation, which utilizes specialized computers (also known as “miners”) that generate digital currency (primarily bitcoin) from the Blockchain. The Company acquired approximately 8,000 miners through its acquisition of Kairos Global Technology, Inc., (“Kairos”) in November 2017, and from Prive Technologies, Inc. (“Prive”) Blockchain Mining Supply & Services Ltd. (“BMSS”) in February 2018.

On January 2, 2018, the Company formed Digital Green Energy Corp. (“Digital Green”), a wholly owned subsidiary, which is seeking to identify environmentally friendly projects with large energy capacity and a cost-effective rate for energy for digital currency mining operations and data center projects. Subsequent to December 31, 2018, activities of Digital Green were suspended. Digital Green’s operations were not significant for the year ended December 31, 2018.

On February 27, 2018, Kairos entered into a lease agreement for an approximately 107,000-square foot facility in Oklahoma City, Oklahoma, which included data center improvements. Upon the execution of the facility lease, the Company consolidated all of its miners at the data center facility.
