What is Proof of Stake (PoS)
Proof of Stake (PoS) is a consensus mechanism used in blockchain networks that enables participants to validate transactions if they hold enough coins and lock them in a smart contract as collateral. For instance, to run an Ethereum node, a network participant must stake 32 ETH. As a result, staking pools and more accessible consensus mechanism variations emerged, such as Delegated Proof of Stake.
