A key advantage of the Proof of Stake system is higher energy efficiency. By cutting out the energy-intensive mining process, Proof of Stake systems may prove to be a much greener option compared to Proof of Work systems. Additionally, the economic incentives provided by Proof of Stake systems may do a better job of promoting network health. Under a Proof of Work system, a miner could potentially own zero of the coins they are mining, seeking only to maximize their own profits. In a Proof of Stake system, on the other hand, validators must own and support the currency they are verifying.
