Proof of Stake (PoS) concept states that a person can mine or validate block transactions according to how many coins he or she holds. This means that the more Bitcoin or altcoin owned by a miner, the more mining power he or she has.

In PoS, each validator owns some stake in the network, ether in the case of Ethereum, that they bond. Bonding stake means you deposit some money into the network, and in some sense use it as a collateral to vouch for a block. In PoW you know a chain is valid because lots of work is behind it, while in PoS you trust the chain with the highest collateral.
