问题如下：
Q. A cryptocurrency miner can earn new digital assets by:
选项：
A.solving complex algorithm puzzles to validate blocks of transactions onto a blockchain network based on a PoS protocol.
B.staking his own cryptocurrencies to validate blocks of transactions onto a blockchain network based on a PoW protocol.
C.validating and locking transactions onto a blockchain irrespective of the consensus protocol adopted by the particular network.
解释：
The correct answer is C. Under both PoW and PoS consensus protocols, the validation of the transactions, or “mining,” always comes with rewards. A successful miner that validates the transactions obtains new digital assets—either a cryptocurrency or a token. For blockchain networks based on the PoW protocol, the miner earns his digital assets by solving complex algorithm puzzles to validate blocks of transactions onto a blockchain network. For blockchain networks based on the PoS protocol, the miner earns his digital assets by staking his own to validate and attest to the new blocks of transactions.
请问 A 和 B 是说反了吗? A 是 POW, B 是 PoS
