Abstract
Both the number of blockchains and the discovered number of applications of blockchain are ever-increasing. Understanding how different blockchains compare in performance has become more important than ever, yet each blockchian paper uses its own inconsistent standards for performance analysis. There are few mechanisms that may allow for consistent performance analysis among multiple blockchains. This paper details the implementation of the first-ever multi-layer blockchain parameter tuning system: Parameter Space Exploration. Our system is primarily targeted at the performance issue but also takes into consideration power consumption. Multi-layer blockchains use a permissioned blockchain to solve performance deficits. We find that the side chain is the determining factor for the performance of a multi-layer system; our side chain is chosen among a set of Byzantine Fault Tolerance (BFT) and Crash Fault Tolerance (CFT) based consensus algorithms as they are more energy-efficient and have higher performance than their Proof of Work (PoW) counterparts. Our proposed Parameter Space Exploration has two elements: (1) The concept of a parameter space; (2) A side-by-side benchmarking system for balanced comparison among different multi-layer blockchains and consensus algorithms. ? 2021 IEEE.
