Real World Asset (RWA) Supply Chain for Smart Factory

This research proposes integrating real-world assets (RWAs) into a blockchain-based supply chain to address traditional challenges of transparency, inefficiency, and security. The framework supports both centralized and decentralized operations within a consortium, ensuring flexibility for diverse organizational needs. Security features include private transactions via Quorum and Hyperledger Besu clients, asymmetric encryption for app-to-app messaging, and confined nodes/services to specific environments. Scalability is achieved through multiple blockchain networks with firewall isolation, while optional cloud integrations enhance efficiency. Organizational identities are managed securely using digital certificates, and a granular block explorer ensures transparency and accountability. This integration improves efficiency, transparency, and trust in food supply chains, benefiting all stakeholders. The proposed RWAs system in the case study is designed with flexibility in mind, allowing for both centralized and decentralized consortium operations. This dual capability ensures that organizations can choose the operational structure that best suits their needs, whether controlled by a single entity or shared across multiple participants. Additionally, the system supports tiered subscriptions within a consortium, enabling diverse organizations with varying requirements to coexist harmoniously. In conclusion, this research demonstrates how integrating real-world assets into a blockchain-based food supply chain can significantly improve efficiency, transparency, and trust. By addressing critical challenges through innovative use of technology, the proposed system offers a robust framework for modernizing food supply chains, ultimately benefiting all stakeholders from producers to consumers.
