Definition
Proof of Stake is a blockchain consensus mechanism in which validators secure the network by staking cryptocurrency rather than using computational power. Validators are selected to verify transactions and create blocks based on the amount of cryptocurrency they stake and other network rules. Proof of Stake is generally more energy efficient than Proof of Work.
Simple Explanation
Proof of Stake secures a blockchain by requiring participants to lock up cryptocurrency instead of using mining hardware.
Example
Ethereum uses Proof of Stake to validate transactions and secure the network.
Why It Matters
Proof of Stake improves scalability and energy efficiency while maintaining network security.
