DLT-Based Verifiable Receipt Credentials for Traceability in EV Battery Supply Chains

Abstract

In the dynamic realm of supply chain management, establishing trust and ensuring transparency are pivotal challenges, particularly in sectors like electric vehicle battery production. This paper introduces a Distributed Ledger Technology (DLT)-based framework utilizing chained Verifiable Credentials (VCs) to enhance traceability and reliability across the supply chain. By integrating smart contracts, our approach automates compliance and operational processes, facilitating real-time verification and fostering stakeholder trust. We present a scalable framework that answers three research questions about honest and accurate data entry by stakeholders, non-repudiation of asset data, and transactional event association with digital documents.
