SECURE DATA SHARING ACROSS SUPPLY CHAIN NETWORKS USING BLOCKCHAIN-INTEGRATED ERP ARCHITECTURE

Abstract

Supply chain networks involve multiple stakeholders, including manufacturers, suppliers, logistics providers, distributors, retailers, and customers, who continuously exchange operational and transactional data through Enterprise Resource Planning (ERP) systems. Traditional centralized ERP architectures often face challenges related to data integrity, unauthorized access, limited transparency, and single points of failure, making secure information sharing difficult across organizational boundaries. Blockchain technology offers decentralized, immutable, and transparent data management capabilities that complement ERP platforms by ensuring trustworthy and tamper-resistant information exchange. This paper proposes a BlockchainIntegrated ERP Architecture for secure data sharing across supply chain networks. The proposed framework combines permissioned blockchain, smart contracts, ERP integration middleware, distributed identity management, and cryptographic security mechanisms to facilitate authenticated and traceable information exchange among supply chain participants. The architecture enhances visibility, prevents data manipulation, strengthens regulatory compliance, and improves operational collaboration without replacing existing ERP infrastructure. The proposed methodology demonstrates improved security, transparency, scalability, and interoperability while reducing disputes, fraud, and manual verification efforts across modern digital supply chains.
