Proof of Stake is a consensus mechanism used to validate transactions and secure a blockchain. Unlike Proof of Work, where miners compete to solve complex mathematical problems, Proof of Stake allows validators to create new blocks based on the number of coins they hold and are willing to “stake” or lock up as collateral.In this system, the more coins a validator owns and stakes, the higher their chances of being selected to validate transactions and earn rewards. This approach encourages users to hold onto their coins rather than sell them, promoting network stability.Proof of Stake is considered more energy-efficient than Proof of Work because it reduces the need for extensive computational power and resources. It can also lead to faster transaction times and lower fees.Overall, this method fosters a sense of ownership among validators and can enhance the security and scalability of a blockchain network, making it an appealing choice for many projects.
