    An alternative consensus mechanism to the proof-of-work system. Instead of using computational power to mine for block rewards, validators use their existing stake in the project’s cryptocurrency to determine how much mining power can be attributed to them. PoS aims to reduce the wasteful energy expended through the heavy computing power required in Proof-of-Work mining.
