Proof of Stake and Proof of Work (PoW) are two general types of consensus mechanisms that are a vital aspect of blockchain technology.Consensus mechanisms are critical to the operation of distributed ledgers - a fundamental element of blockchain technology that allows it to operate without a central authority. Reading through various best crypto exchange reviews online, you’re bound to notice that one of the things that most of these exchanges have in common is that they are very simple to use. This mechanism does not involve miners, and there is no need for high computational power, making it a greener alternative to Proof of Work. Proof of Stake in Simple Terms Introduction Proof of Work vs. On the other hand, Proof of Stake does not need highly complex sums to be solved, meaning that the electricity costs to verify transactions are substantially lower.
