Explanation of Responses:

1. Pursuant to the Riot Blockchain, Inc. 2019 Equity Incentive Plan, as amended, (the "Plan") each time-based restricted stock unit ("RSU") and performance-based restricted stock unit ("PSUs") represents a contingent right to receive one share of the Issuer's common stock, no par value per share, ("Common Stock") subject to any net settlement permitted under the Plan and approved by the Issuer's Compensation and Human Resources Committee (the "Committee"), following vesting and settlement by the Issuer.

2. Represents the total direct and indirect ownership of the indicated security held by the Reporting Person immediately following the reported transaction.

3. Represents net settlement in connection with the conversion 36,000 vested PSUs and 2,657 vested RSUs into shares of the Issuer's Common Stock, as permitted under the Plan and approved by the Committee.

4. On December 3, 2021, the Committee determined that, as of the end of the third fiscal quarter of 2021, the performance criteria for 6,000 PSUs had been achieved and, therefore, 6,000 PSUs became vested and eligible to be settled by the Issuer in accordance with the Plan. The PSUs were issued to the Reporting Person under the Plan pursuant to the Performance Restricted Stock Unit Award Agreement, dated as of August 12, 2021, between the Issuer and the Reporting Person (the "Award Agreement"), as approved by the Committee.

5. The conversion of 36,000 PSUs reported in Table II represents the settling by the Issuer of the vested portion of the PSUs granted to the Reporting Person pursuant to the Award Agreement, which vested upon the Committee's determination that performance criteria corresponding to 36,000 of the PSUs granted to the Reporting Person had been achieved.

6. The conversion of 2,657 RSUs reported in Table II represents the settling of the vested portion of the 10,630 RSUs awarded to the Reporting Person by the Issuer under the Plan on July 15, 2021, pursuant to an award agreement between the Issuer and the Reporting Person dated as of the grant date, which are eligible to vest in four equal quarterly installments following the grant date.
