End-to-End Supply Chain Traceability Using Blockchain

This work presents an innovative blockchain-based framework designed to enhance end-to-end traceability within modern supply chains, addressing critical challenges such as fragmented visibility, inconsistent data, and a lack of trust between stakeholders. Traditional supply chains often struggle with these issues, leading to inefficiencies, fraud, and compliance risks. The proposed system utilizes decentralized ledger technology (DLT) to create an immutable, transparent record of a product's journey from origin to final destination, capturing detailed information on provenance, transformation, and transportation at each stage. Key to the system's functionality is the integration of Internet of Things (IoT) sensors for real-time data collection, enabling continuous monitoring of goods throughout the supply chain. Smart contracts automate compliance enforcement by ensuring that predefined conditions are met without manual intervention, reducing human error and administrative overhead. Python-based blockchain scripting is used to ensure secure event logging, further enhancing the system's reliability and integrity. In addition to real-time tracking and tamper-proof record-keeping, the solution leverages predictive analytics to increase operational resilience. By analyzing historical data, the system can anticipate potential disruptions and optimize decision-making processes to mitigate risks. This proactive approach improves overall supply chain efficiency and responsiveness. The proposed system not only fosters greater transparency and reduces the risk of fraud but also ensures regulatory compliance and builds consumer trust. By enabling immutable and real-time tracking, the framework lays the foundation for more resilient, sustainable, and trustworthy global supply chains, empowering industries to meet the growing demands for accountability and sustainability in today’s interconnected world.
