What Is “Proof-of-Stake” (PoS)?

Proof-of-Stake (PoS) is a consensus mechanism where network participants (validators) are chosen to create new blocks and validate transactions based on the amount of cryptocurrency they have "staked" (locked up) as collateral. PoS is generally more energy-efficient than Proof-of-Work and aims to achieve network security through economic incentives and penalties (slashing).
