Performance Evaluation of a Hyperledger Fabric–Based Permissioned Blockchain Network for Cross-Border Regulatory Applications

Permissioned blockchain platforms operate as peer-to-peer distributed systems whose performance, scalability, and resource behavior are critical for deployment in cross-border regulatory applications. Effective regulatory coordination within Free Trade Areas (FTAs) is nevertheless hindered by fragmented National Quality Infrastructure (NQI) systems, limited interoperability, and weak institutional trust mechanisms. This study addresses these challenges by designing and experimentally evaluating a permissioned blockchain network based on Hyperledger Fabric to support interoperable, transparent, and auditable NQI processes. Using the African Continental Free Trade Area (AfCFTA) as an illustrative regulatory environment, the proposed system models core regulatory transactions—such as standards submission and endorsement, accreditation recording, and certificate verification—through smart contracts executed across multiple peer organizations. The design distinguishes between write-intensive submission transactions, which require multi-peer endorsement and ordering, and read-only verification and audit transactions executed locally at peer nodes. The framework is implemented in Go using the Fabric Contract API and evaluated on Hyperledger Fabric v2.5 using Hyperledger Caliper v0.6.0. Experimental results under varying concurrency and load conditions demonstrate low-latency read performance (sub-15 ms) and a write-throughput ceiling of approximately 400 TPS, attributable to endorsement and ordering overheads in the consensus pipeline. These results provide empirical insights into performance trade-offs in permissioned peer-to-peer blockchain networks and confirm the suitability of Hyperledger Fabric for compliance-driven, multi-institutional regulatory environments.
