Note 1.  Organization:

Nature of operations:

Riot Blockchain, Inc. (the “Company” or “Riot Blockchain”) was originally organized on July 24, 2000, as a Colorado corporation.  Effective October 19, 2017, the Company's name was changed to Riot Blockchain, Inc., from Bioptix, Inc., and 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 acquisitions of Kairos Global Technology, Inc. (“Kairos”) in November 2017, and from Prive Technologies, Inc. (“Prive”), and separately from Blockchain Mining Supply & Services Ltd. (“BMSS”) in February 2018.
