Proof of Stake (PoS)

Proof of stake (PoS) means that a person can mine or validate block transactions according to how many coins one holds and puts up for staking. The mechanism reduces the amount of CPU work needed to verify transactions and blocks that keep a given blockchain secure.

Moreover, PoS changes the block verification process by using the computers of coin owners. The holders offer their crypto coins as collateral for a chance to validate blocks. An owner that stakes their coins to do this becomes a "validator."

What Are Proof of Stake (PoS) Validators?

Validators are the people on a blockchain who stake their currency to validate blocks and earn rewards. Proof of stake consensus algorithms select a validator for the next block based on various factors, such as how much cryptocurrency the person holds, or how long they’ve been staking.
