As traditional supply chain operations continue to pose challenges to the businesses, the adoption of Blockchain to solve issues of traceability and integrity in global supply and logistics networks is increasingly evident and persuasive across multiple geographies. The objective of this research study was to build a Blockchain Optimized Chain of Accountability (BOCA) to eliminate delays, inaccurate inventories and vulnerability to fraud; thereby enhancing transparency, accountability and efficient supply chain ecosystem. The methodology used is the Structured System Analysis and Design methodology to allow necessary changes, and adjustment to the system to be made quickly; resulting in a more robust, and user-friendly interface that aligned with users’ needs and expectations. The system multi-tier architecture makes transactions visible to authorized users and the automatic trigger of a smart contract once a product moves from one party to another further offers secure and immutable transaction. The programming languages and tools used for the coding and development of the system are JavaScript (Vue.Js) and HTML/CSS for the user interfaces; JavaScript (Node.Js) for the blockchain; Go for development of blockchain; and SQL for data storage. The innovation will enable companies, businesses or individuals to order goods and raw materials for production and keep track of their inventory, make secure payments, gather, analyze and maintain tamper-proof record of supply chain events. By integrating smart contracts and real-time tracking, the system will enhance transparency and trust among stakeholders and largely benefit companies aiming at modernizing their supply chain logistics networks across the globe. The paper thus offers valuable insights for academics, practitioners, and policymakers to refine and advance blockchain-based logistics solutions in the global supply chain ecosystems.
