What are some advantages of Proof of Stake (POS) mining over Proof of Work (POW) mining? (Select three.)
A . Energy efficient in regards to that it could consume for electricity as compared to PoW
B . Faster Hashing algorithms
C . No need for expensive compared to POW
D . Faster validations compared to POW
E . Better blockchain security compared to POW

Answer: A,C,D

Explanation:

This eliminates the below challenges from PoW and believed to have an advantage.

No need of expensive hardware (a normal laptop or computer running the respective coin’s Validator client will do as long as your laptop or computer is online)

Energy efficient as it won’t consume high electricity as PoW does More loyal Validators As higher the stake the Validators have for a long time, more chances for the Validator to be picked up for “forging” and earn the transaction fee Faster validations
