Secure Blockchain Smart Contracts for Efficient Logistics System

Blockchain and allied technologies have been investigated as panacea for the problems faced by supply chain and logistics industry. However, earlier literatures have focused on limited aspects of a typical supply chain such as monitoring assets, securing traceability widely neglecting data integrity, and data access. To overcome such drawbacks, the current paper proposes secure smart contracts based on the ERC20 interface in a permissioned blockchain with relevant processes and functions to obtain a holistic framework for securing the supply chain and logistic operations. The efficacy of the proposed framework was demonstrated in a case study. It was found that critical loopholes in a current supply chain can be overcome using the proposed framework. Additionally, several outlines for future research are outlined.
