Permissioned Blockchain-as-a-Service: Architecting Secure and Efficient Private Blockchain Networks

Public distributed ledger systems often fall short for corporate use due to limited transaction processing capabilities, high costs, suboptimal consensus mechanisms, and inadequate data protection. As demand for advanced transaction-oriented analysis grows, distributed ledger technologies have gained attention across various sectors, driving the development of diverse blockchain architectures. This article examines the Hyperledger Fabric framework, focusing on its deployment using local command-line interfaces, architecture, and transaction mechanisms. Our proof of concept demonstrates the creation of resilient, scalable blockchain networks by applying modern software principles to distributed ledgers. We break down Hyperledger Fabric into containerized microservices, orchestrated with Docker and Kubernetes, to enhance flexibility and scalability. The study evaluates the Hyperledger Fabric architecture, data handling within the ledger, and operational efficiency through a rigorous analysis of transactions per second (TPS), latency, and overall performance. These metrics are assessed in a setup that closely emulates real-world scenarios, with multiple organizations participating in the distributed ledger system. This provides insights into the framework's viability for enterprise blockchain solutions.
