BLOCKCHAIN-BASED MULTI-TIER SUPPLIER TRACEABILITY FOR RESILIENT ENTERPRISE SUPPLY CHAINS

Abstract

Modern enterprise supply chains consist of multiple interconnected supplier tiers, including raw material providers, manufacturers, distributors, and logistics partners. Managing transparency, traceability, and resilience across these multi-tier networks remains a significant challenge due to fragmented information systems, limited visibility, and dependency risks. Traditional Enterprise Resource Planning (ERP) systems provide internal operational management but often lack mechanisms for secure crossorganizational supplier tracking. This paper proposes a Blockchain-Based Multi-Tier Supplier Traceability Framework for Resilient Enterprise Supply Chains by integrating blockchain technology, ERP systems, smart contracts, IoT monitoring, and intelligent analytics. The proposed framework enables secure tracking of supplier activities across multiple tiers through decentralized records, immutable transaction histories, and automated verification mechanisms. Blockchain improves trust and data integrity, while ERP integration supports real-time operational management. The framework enhances supplier visibility, risk identification, compliance monitoring, and supply chain resilience. Experimental evaluation demonstrates improvements in traceability accuracy, transparency, supplier risk management, and operational reliability.
