Dataset for Blockchain-Based Transaction Verification System Study

Package Contents

The dataset package includes the following components:

Hyperledger Fabric Transport Chain – Contains the chaincode implementation, client gateway application for invoking and testing smart contract functions, organization setup scripts, and network management tools. This component provides the full source code used for blockchain-based transaction creation and verification, including the standardized message format implementation described in the paper.

JMeter Evaluation Tests – Includes Apache JMeter test plans (.jmx files), parameterized CSV datasets, and generated HTML reports. These files correspond to the performance evaluation experiments presented in the paper, covering throughput, latency, and APDEX metrics under various transaction loads.

Custom Verifier – A command-line application for verifying decentralized identity credentials using the Polygon ID protocol. It performs zero-knowledge proof (ZKP)–based validation of user credentials (e.g., age, student status) without disclosing personal data.

Identity Issuer Node – The trusted authority server responsible for issuing verifiable digital credentials to users. It generates and signs credentials according to the Polygon ID protocol, enabling secure and privacy-preserving identity management.

Verifier Backend – A lightweight backend service that validates users’ ZKP-based proofs during the authentication process. It operates in coordination with the Custom Verifier and the Hyperledger Fabric network.

ID Wallet – Contains the identity controller module and essential components for the mobile digital identity wallet. The full implementation is available upon request for research or evaluation purposes.

Screenshots & Videos Examples – Contains a demonstration video showing how users add and manage their digital identity credentials in the mobile wallet application., as well as screenshots from the Hyperledger Explorer interface, Grafana monitoring dashboards, and example JSON messages used in the evaluation.

REST API JSON Files – Includes example API requests for the transport blockchain network. These JSON file can be imported into API testing tools (e.g., Insomnia) to test chaincode functions such as transaction creation and audit retrieval.
