Hybrid Blockchain-Cloud Architecture for Real Time Cargo Tracking in Airport Supply Chains

Modern airport supply chains demand real-time visibility, security, and transparency across all cargo-handling operations.However, current centralized systems are often prone to inefficiencies, data tampering, and limited traceability.This paper presents a hybrid architecture that integrates blockchain and cloud technologies to streamline airport cargo tracking.Leveraging Ethereum-based smart contracts deployed via Ganache and real-time cloud synchronization using Firebase Firestore, the proposed system ensures both immutability and accessibility.A React.js-based frontend provides an intuitive user interface for cargo management, while Python scripts automate bulk data processing from CSV files.The architecture aims to eliminate manual errors, enhance security, and offer scalable deployment across airport logistics.The system was tested with thousands of cargo records, demonstrating seamless synchronization between the blockchain and cloud layers.
