Proof-of-Stake (PoS) is a consensus mechanism used by some blockchain networks to validate transactions and add new blocks to the chain. In a PoS system, validators, or “stakers,” are chosen to create new blocks and validate transactions based on the amount of cryptocurrency they hold and “stake” in the network. This means that instead of relying on mining power and computational resources, as in Proof-of-Work (PoW), PoS systems rely on the economic incentives of the validators to maintain the security and integrity of the network. Validators are incentivized to act in the best interest of the network, as their stake can be slashed if they validate fraudulent or malicious transactions. PoS systems are generally more energy-efficient than PoW systems, as they do not require large amounts of computational power to validate transactions.
