Algorand’s Pure Proof of Stake (PPoS) consensus mechanism is a variation of the traditional Proof-of-Stake (PoS) consensus mechanism. It is a decentralized Byzantine agreement protocol with a low barrier to entry, requiring only one ALGO to become a participating node. PPoS strives for transaction processing speed and finality. To coordinate its participation nodes, it employs a verifiable random function (VRF).
