- Purpose: The purpose of this study was to suggest an improved version of Proof-of-Nonce (PoN) algorithm, whichis a distributed consensus algorithm used for block chain system.Methods: First, we used response surface method for design of experiment that is to generate experimental pointsconsidering non-linear relationship among variables. Then, we employed overlapped contour plots for visualizingthe impact of control variables to performance target.Results: First, we modified the consensus procedure of the existing PoN algorithm by diminishing the content ofthe exchanged message. Then, we verified the performance improvement of the new PoN algorithm by performinga numerical experiment and paired t-test. Finally, we established new regression models for consensus time andTransactions per second (TPS) and proposed a method for optimizing control variables for obtaining performancetarget.Conclusion: We could improve the performance of the previous version of PoN algorithm by modifying the contentof the exchanged message during 4-steps of consensus procedure, which might be a stepping stone for designingan efficient and effective consensus algorithm for blockchain system with dynamic operation environment.
