【Abstract】Information sharing is essential for coordination and stakeholder integration and is crucial to achieving sustainable supply chain operations. Furthermore, improved information sharing assists retailers by reducing the time spent looking for alternative suppliers to meet the unexpected demand surge during pandemics. Recent advances in networking and distributed ledger technologies have enabled secure, improved information communication and broader connectivity. However, due to system interoperability, information quality, confidentiality, and trust, information cannot be exchanged seamlessly, resulting in the inefficiency of managing supply chain operations. In this paper, we propose a blockchain-based inventory sharing approach based on smart contracts using a private Ethereum network to link suppliers and retailers. Our approach combines blockchain technology with decentralized storage to increase transparency, trust, and security of supply chain transactions. We present a generalized mechanism for secure information sharing that includes comprehensive algorithms to capture supply chain stakeholder interactions that enhance trust among participating entities. The smart contract was developed and validated using the Remix IDE, and the code is made publicly available on Github. We analyze the solution for various security vulnerabilities and provide a detailed cost analysis for various stakeholder transactions in the supply chain. Our solution demonstrates that a blockchain-based approach reduces inefficiencies, is economical, commercially viable, and provides improved information connectivity among supply chain stakeholders in a trusted and secure way.
