Abstract
The widespread application of the Hyperledger Fabric platform and the timeliness requirement of transactions on the platform necessitate the effective performance evaluation of transaction processing. The existing evaluation researches on Hyperledger Fabric ignored transaction endorsement failure (due to transaction endorsing duration timeout) and/or ignored block timeout. This paper considers these two timeout constraints and develops a hierarchical model for Hyperledger Fabric v1.4 transaction process from the time when transactions are submitted by clients until the completion of validating/committing transactions as a block. Formulas for calculating performance measures, including platform throughput, transaction rejection probability and mean transaction response delay, are derived. Extensive numerical analysis and simulations are carried out to verify the approximate accuracy of the model and formulas. Moreover, numerical analysis is applied to illustrate the impact of various parameters on performance measures.
