Explanation of Responses:

1. Under the Riot Blockchain, Inc. 2019 Equity Incentive Plan, as amended, (the "Plan") each service-based restricted stock unit ("RSU") and performance-based restricted stock unit ("PSU") 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. Pursuant to the Plan, RSUs and PSUs are subject to forfeiture until vested, and are contingent on the Recipient's continued employment or service with the Issuer through vesting.

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

3. Represents net settlement in connection with the conversion of vested RSUs and PSUs into shares of the Issuer's Common Stock noted in Table II of this report, as permitted under the Plan and approved by the Committee.

4. Represents the settlement following vesting of 50,000 PSU granted, as of August 12, 2021, to the Reporting Person under the Plan, which vested upon the Committee's determination that the performance criteria corresponding to 50,000 PSUs had been achieved.

5. On March 18, 2022, the reporting person filed a Form 4 which inadvertently reported that, following his conversion of vested RSUs on Table II, the number of derivative securities beneficially owned totaled 41,321. The correct number of derivative securities beneficially owned following the reported transaction were 41,315.

6. Represents the settlement following vesting of the remaining balance of the 10,630 RSU granted, as of July 15, 2021, to the Reporting Person under the Plan, which were eligible to vest in four approximately equal quarterly installments following the grant date.
