Dataset for A Low-Code Orchestration Middleware for Secure and Transparent IoT–Blockchain Integration

This repository contains the reproducibility package for the manuscript “A Low-Code Orchestration Middleware for Secure and Transparent IoT–Blockchain Integration”.It provides the core artifacts required to inspect, deploy, and execute the proposed IoT-to-blockchain orchestration pipeline using n8n, a Solidity smart contract, and a containerized environment.

The package is organized to support technical transparency and experimental repeatability, including:

Smart-contract source code used as immutable audit anchor.

n8n workflow definition in JSON format (importable in n8n).

Workflow visual snapshot (PNG) for fast structural inspection.

Docker Compose deployment file to run n8n in a reproducible way.
