Proof of Stake (PoS for short) is a process that ablockchain network uses to reach a consensus about which participant is allowed to generate the next block. A weighted random selection is used. The weights of the individual participants are determined based on the duration of participation and/or assets (the "stake"). In contrast to theProof of Work used with Bitcoin, Proof of Stake does not require time- and energy-intensive mining. It is not possible to take over the network simply by owning computing power ("51% attack").^[1][2]
