Proof of Stake (POS)

A novel consensus protocol in which, instead of mining, nodes can validate and make changes to the blockchain on the basis of their existing economic stake. Unlike proof of work or PoW, a person can validate transactions and create new blocks based on their individual wealth (i.e. stake) such as the total number of coins owned. One of the key advantages that PoS has over PoW is lower energy consumption.
