    'Note 9 – Employee Benefit Plans The Company maintains defined\ncontribution benefit plans under Section 401(k) of the Internal Revenue Code\ncovering substantially all qualified employees of the Company (the “401(k)\nPlan”).\n\nUnder the 401(k) Plan, the Company may make discretionary\ncontributions of up to 100 % of employee contributions.\n\nFor the six months\nended June 30, 2024 and 2023, the Company made contributions to the 401(k)\nPlan of $ 109,000 and $ 95,000 , respectively.Note 10 – Liquidity The Company\nfollows “ Presentation of Financial Statements—Going Concern (Subtopic\n205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as\na Going Concern ”.\n\nThe Company’s financial statements have been prepared\nassuming that it will continue as a going concern, which contemplates\ncontinuity of operations, realization of assets, and liquidation of\nliabilities in the normal course of business.\n\nAs reflected in the financial\nstatements, the Company has historically incurred a net loss and has an\naccumulated deficit of approximately $ 133,148,000 at June 30, 2024, and net\ncash used in operating activities of approximately $ 1,693,000 for the\nreporting period then ended.\n\nThe Company is implementing its business plan and\ngenerating revenue; however, the Company’s cash position and liquid crypto\nassets are sufficient to support its daily operations over the next twelve\nmonths.Our Form S-3 expired on August 14, 2024.\n\nThe Company filed a new Form\nS-3 on February 14, 2024.\n\nAs a result of SEC comments, the new Form S-3 has\nnot yet gone effective and therefore we may not sell shares under the ATM\nAgreement.Note 11 – Subsequent Events The Company evaluates events that have\noccurred after the balance sheet date but before the financial statements are\nissued.\n\nBased upon the evaluation, the Company did not identify any recognized\nor non-recognized subsequent events that would have required adjustment or\ndisclosure in the financial statements other than disclosed.',

The offering of the shares was made pursuant to our shelf registration statement on Form S-3 including the prospectus dated January 5, 2022 contained therein, and the prospectus supplement dated May 25, 2023. We received approximately $ 15.3 million in net proceeds from the registered direct offering after deducting placement agent fees and offering expenses.February 2024 Registered Direct Offering and Concurrent Private PlacementIn February 2024, we entered into a securities purchase agreement with certain purchasers, pursuant to which we sold 13,086,151 shares of common stock at a price of $ 4.585 per share in a registered direct offering. The offering of the shares was made pursuant to our shelf registration statement on Form S-3, including the prospectus dated January 5, 2022 contained therein, and the prospectus supplement dated February 28, 2024.	1
