Proof-of-Stake (PoS) is a consensus mechanism used to validate transactions and add new blocks to a blockchain. Unlike Proof-of-Work (PoW), which relies on energy-intensive mining, PoS allows participants to create and validate new blocks based on the number of coins they hold and are willing to “stake” as collateral.In a PoS system, users who hold a certain amount of the cryptocurrency can participate in the block creation process. The more coins a user stakes, the higher their chances of being selected to create a block and earn rewards. This method is considered more energy-efficient because it doesn’t require powerful hardware to solve complex mathematical problems.Staking can also encourage users to hold their coins longer, as they earn rewards for participating in the network. However, there are risks involved, such as the possibility of losing staked coins due to network vulnerabilities or penalties for malicious behavior.Overall, PoS promotes decentralization and security while reducing the environmental impact associated with traditional mining methods.
