In proof-of-work, miners prove they have capital at risk by expending energy. Ethereum uses proof-of-stake, where validators explicitly stake capital in the form of ETH into a smart contract on Ethereum. This staked ETH then acts as collateral that can be destroyed if the validator behaves dishonestly or lazily. The validator is then responsible for checking that new blocks propagated over the network are valid and occasionally creating and propagating new blocks themselves. In proof-of-stake, validators are like bouncers at a club, staking their ETH as collateral for their behavior. This ETH acts as a deposit that can be taken away if they don't follow the rules and validate new blocks correctly. In the same way that a bouncer must monitor the club to ensure everyone is behaving appropriately, a validator must monitor the blockchain network to check for valid blocks.
