Proof of Stake (PoS) is a consensus mechanism that offers an energy-efficient alternative to Proof of Work (PoW). In PoS, validators are chosen to create new blocks and validate transactions based on the number of coins they hold and are willing to "stake" as collateral. This reduces the need for extensive computational power and energy consumption. Many newer blockchains, such as Cardano and Solana, use PoS, and Ethereum is transitioning to PoS with its Ethereum 2.0 upgrade.
