Preferential Delegated Proof of Stake (PDPoS)—Modified DPoS with Two Layers towards Scalability and Higher TPS

Security and a decentralized system are identical unique features of Blockchain. In recent times, blockchain-based cryptocurrency has become mainstream, but the growth value transactions application services remain volatile. Among all these applications, finding fast consensus in large-scale blockchain network frequently requires extreme energy for huge computations storing complete verification. These problems prevent further commercialization. Here, we present solution to this problem. paper, introduce revised algorithm, PDPoS, address scalability transaction efficiency limitations. The symmetry between Proof Stake (PoS) Delegated (DPoS) is PoS. However, their ways working dissimilar. review existing algorithms, such as work (PoW), PoS DPoS, they directly relating our proposed work: PDPoS. We highligh (DPoS)–based crypto-currencies, have much higher per second (TPS) than PoW-based currencies. Then, describe works steps Simulation results PDPoS with two layers result improved efficiency. used TPS evolution criteria showing that more efficient DPoS. This makes relevant it less consumption.
