Proof of Stake (POS)
An acronym for proof-of-stake, which is an alternative method of veryfing blockchain transactions. Using this model, holders of the native cryptocurrency lock a part of their holdings in a process known as staking. By doing so they become candidates for validating transactions into the blockchain, also known as mining. Though miners are chosen by an algorithm, the more coins the holders stake, the higher the probability of them being chosen. If they are chosen to become miners, the holders can receive more coins as a reward.
