Certified Blockchain Solutions Architect (CBSA) — Question 11

What consensus algo uses a method of sending coins to an address where they cannot be retrieved?

Answer options

• A. Proof of Stake
• B. Proof of Activity
• C. Proof of Burn
• D. Proof of Sending

Correct answer: A

Explanation

The correct answer is A, Proof of Stake, as it involves locking up coins to validate transactions rather than sending them to a non-retrievable address. Options B, C, and D do not describe the method of permanently sending coins to an address; Proof of Activity and Proof of Sending are not standard consensus mechanisms, while Proof of Burn refers to a different process of destroying coins.
