Description
Summary:Blockchain, often integrated with distributed systems and security enhancements, has significant potential in various industries. However, environmental concerns and the efficiency of consortia-controlled permissioned networks remain critical issues. We use a Stochastic Petri Net model to analyze transaction flows in Hyperledger Fabric networks, achieving a 95% confidence interval for response times. This model enables administrators to assess the impact of system changes on resource utilization. Sensitivity analysis reveals major factors influencing response times and throughput. Our case studies demonstrate that block size can alter throughput and response times by up to 200%, underscoring the need for performance optimization with resource efficiency. •Tackles Hyperledger Fabric performance using SPN to assess responsiveness and resources.•Confirms SPN model accuracy through extensive testing, simulating real-world scenarios.•Analyzes configuration changes’ effects on MRT and throughput, aiding optimization.•Highlights block size and transaction rates’ impact, guiding administrators on settings.
