Proof of Stake (PoS) is a consensus mechanism used by various blockchain networks to validate transactions and create new blocks. Unlike Proof of Work, where miners compete to solve complex puzzles, PoS allows validators to create new blocks based on the number of coins they hold and are willing to “stake” as collateral.In PoS, those who wish to validate transactions must lock up a certain amount of their cryptocurrency. This stake serves as a guarantee that they will act honestly. If they attempt to deceive the network, they risk losing their staked coins.The selection of validators in PoS is often proportional to the amount they hold, encouraging users to invest in the network. This method is generally seen as more energy-efficient than PoW, as it reduces the need for extensive computational resources. By reducing energy consumption and making participation accessible to more users, PoS aims to create a more sustainable and democratic blockchain ecosystem, where users have a direct stake in the network’s success.
