Blockchain technology has been considered as a viable solution to address the concerns of trust and central points of failure in centralized systems. From it's inception, blockchain has been hailed for its promise of failure resilience, alteration intolerance and privacy preservation. For these reasons academia has sought methods to widen the scope of blockchains applicability however blockchain's qualities must be challenged at scale before the platform may be considered as a viable solution for major service providing organizations. Our thesis seeks to generate answers for two question, how efficient are the major subsystems of Hyperledger Fabric and does there exist observable trends in performance degradation as network configurations alter. We approach this by developing a hierarchical model based on Markov Chain queuing theory and Hyperledger Caliper to characterize the private blockchain Hyperledger Fabric. Our results isolate performance metrics of the major blockchain phases: endorsing, ordering and validation/committing. We observed changes in performance as network sizes vary along with varying transaction work loads. Lastly, our results have validated the bottleneck associated with higher security policies noticed during peer endorsing and validation.
