One of the most prominent features of the Ontology platform is its implementation of a novel type of consensus mechanism that consists of a combination of the BFT (Byzantine Fault Tolerance) consensus protocol and VRF (Verifiable Random Functions). This is known as the Ontorand Consensus Engine (OCE) on the platform or the VBFT consensus mechanism. Essentially, the OCE selects which nodes will participate in the consensus validation using a VRF, and consensus is reached by the Byzantine Fault Tolerance algorithm. In essence, they are. Trying to build a scalable project that would be wide acceptable and provide users with everything they need as related to transactions
