Proof of Stake (PoS) is a class of consensus algorithm that selects and rewards validators as a function of a validator’s economic stake in the network. Unlike PoW, the probability of creating a block in a PoS network is not a result of hash power from burning energy, but rather the result of economic value-at-loss. Proof of Stake will be the consensus mechanism that Ethereum 2.0 uses to maintain the network. Unlike Proof of Work networks, Proof of Stake networks can achieve finality. (consensys)
