Proof of Stake (PoS) is a consensus mechanism used by some blockchain networks to validate transactions and create new blocks. Instead of relying on energy-intensive mining, PoS allows participants, known as validators, to create new blocks based on the number of coins they hold and are willing to “stake” as collateral.In PoS, when a validator is chosen to create a block, they receive transaction fees as a reward. This process is generally more energy-efficient than Proof of Work (PoW), reducing the environmental impact and costs associated with mining.The probability of being selected as a validator often depends on the amount of currency staked and the duration of the stake. This encourages holders to keep their assets in the network, promoting stability and security. Additionally, PoS mechanisms can include penalties for malicious behavior, ensuring validators are incentivized to act honestly.Overall, Proof of Stake is seen as a way to enhance scalability, promote decentralization, and provide a more sustainable alternative to traditional mining methods.
