A Systematic TOGAF-Driven Framework for Blockchain-Based Food Traceability with Access Control Lists

The global food supply chain involves multiple stakeholders, including farmers, manufacturers, distributors, retailers, and consumers, requiring a robust traceability system to ensure food security, transparency, and consumer trust. However, existing systems face significant challenges, such as limited transparency, data tampering risks, and inefficient access control mechanisms, leading to supply chain inefficiencies and regulatory concerns. This framework paper develops a systematic model that integrates The Open Group Architecture Framework (TOGAF), blockchain technology, and Access Control Lists (ACLs) to address these limitations. The TOGAF Architecture Development Method (ADM) is applied to design and implement the framework, focusing on business architecture, data security, and stakeholder collaboration. The framework ensures data immutability, privacy, and secure access control while enhancing scalability and adaptability across diverse supply chains. By integrating these technologies, the proposed framework is expected to enhance traceability, strengthen data security, and improve stakeholder engagement, making food supply chains more reliable and transparent for regulators and consumers. The novelty of this framework lies in its unique integration of TOGAF-driven enterprise architecture, blockchain, and ACLs, creating a privacy-preserving, tamper-proof food traceability system. This integration enhances industry practices and provides a scalable, sustainable solution, contributing to global food security and consumer trust.
