WHAT IS PROOF OF STAKE?
Proof of Stake (PoS) is an algorithm that helps the blockchain to secure every transaction. Transactions are bundled in one “block” and several blocks together are called the blockchain. In order for the blockchain to be reliable there needs to be consensus about the transactions. In PoS-based cryptocurrencies the creator of the next block is chosen randomly, with consideration to their weighting. Your weight is determined by the amount of coins in your wallet and the time they have been waiting to stake. This means that when you hold mature coins and your wallet is unlocked, you have the chance to be selected as the creator of a block. Once that happens you get a reward for helping to secure the blockchain.
