This appears to be a follow-up question to a topic you discussed earlier in the interview. Whenever you answer a question during an interview, the interviewer may ask follow-up questions. These can occur immediately after the original question or later in the interview. Follow-up questions indicate that the interviewer has a specific interest in a topic they are asking about. This signals you to discuss the topic in more detail to demonstrate your knowledge and capabilities in this area.

"Proof-of-Stake and Proof-of-Work or two consensus algorithms used within a blockchain to reach a consensus on the ledger's current state. Proof-of-Work was the original consensus algorithm developed for blockchains. It is used for confirming transactions and producing new blocks within that chain. This is the mechanism that Miners use to compete with each other and earn rewards. Proof-of-Stake virtualizes the consensus process. It requires that a set of nodes stake their cryptocurrencies to the transaction validations."
