Proof of Stake Layer refers to a system used to validate transactions and create new blocks in a blockchain. Unlike Proof of Work, where miners compete to solve complex mathematical problems, Proof of Stake allows participants 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, validators are selected to create new blocks and confirm transactions based on factors such as the amount of cryptocurrency they hold and how long they have held it. This method reduces energy consumption and increases efficiency, as it eliminates the need for intensive computational work.Staking rewards are given to participants for their contributions, incentivizing users to hold their coins rather than sell them. This helps with network security and stability since users who stake their coins have a vested interest in the network’s success.Overall, Proof of Stake Layers promote decentralization and sustainability in blockchain networks while providing participants with the opportunity to earn rewards.
