Proof-of-Stake (PoS)Proof-of-Stake (PoS), like Proof-of-Work (PoW), is a consensus algorithm for the verification/creation of blocks on a blockchain. In contrast to proof-of-work (PoW), it is not the highest computing power but the monetary share (stake) in the network that decides who is authorised to create a new block. To ensure the security of the network, a weighted random algorithm is used to select the validator. Those who hold a higher stake have a greater chance of being considered by the algorithm due to the weighting. As a reward for the successful creation of a new block, the participant (staker) receives a portion of the transaction fees. To gain control of a blockchain that functions according to the PoS consensus method, 51% of the network's circulating tokens are required. The second largest blockchain, Ethereum (ETH), is currently undergoing a transformation process from PoW to PoS (Ethereum 2.0). (Publication date 25/05/2021)
