Performance Evaluation of Multi-Organization E-Government Based on Hyperledger Fabric Blockchain Platform

E-governments can face various security problems due to the nature of online systems and the sensitive information they handle. Some of these security issues include: cyberattacks, data breaches, Identity theft, access control, and many others. Permissioned blockchain is one of the cutting-edge technologies that can help to reduce the impact of security vulnerabilities of e-governments. In this work, six organizations as a case study have adopted, two scenarios performed to analyze the performance of hyperledger fabric (a permissioned blockchain platform). In these two scenarios, several parameters have changed, including: transaction send rates, block sizes, number of organizations, and number of clients. The organizations have added gradually to conclude the effect of multi-organization on the throughput, latency, and scalability of the system. Good throughput and latency results were obtained by increase the block size to about 100 transactions per block. Within three to four organizations, the throughput and latency results were accepted, but adding more organizations, the throughput and latency have been affected negatively. Also, it has concluded that with few users in the system, the throughput and latency were reasonably good. Still, with adding more clients, the throughput decreased, and the latency increased rapidly.
