Blockchain-enabled Supplier Relationship Management for Sustainable Purchasing and Supply Chain Transparency

Project Abstract

Blockchain-enabled Supplier Relationship Management (SRM) for Sustainable Purchasing and Supply Chain Transparency investigates how distributed ledger technology (DLT) can transform the governance of supplier networks, enhance traceability, and drive sustainability across procurement processes. This study adopts a multi-method approach combining a comprehensive literature review, qualitative interviews with procurement and sustainability professionals, and a mixed-methods case study across three supply chains in manufacturing, consumer electronics, and fast-moving consumer goods. The core objective is to develop a scalable SRM framework that integrates blockchain-based provenance, smart contracts, and real-time data analytics to monitor supplier performance, compliance with environmental and social standards, and ethical sourcing practices. The research identifies key drivers for adopting blockchain-enabled SRM, including reduced information asymmetry, improved contract compliance, enhanced risk management, and greater stakeholder trust, while also addressing challenges related to data governance, interoperability, scalability, and cost. The abstract discusses the design of a reference architecture that layers immutable transaction records, verifiable credentials, and consent-based data sharing to enable end-to-end traceability from raw material sourcing to final product delivery. It also presents a governance model for supplier onboarding, performance scoring, and corrective action workflows powered by smart contracts that automatically trigger audit trails, payments, and penalties aligned with negotiated terms and sustainability criteria. A critical analysis examines how blockchain interoperability with existing ERP, MES, and sustainability reporting frameworks (e.g., GRI, SASB) can ensure data harmonization without compromising privacy. The study evaluates risk management implications, including counterfeit materials, supplier insolvency, and geopolitical disruptions, and demonstrates how automated, auditable records reduce audit costs and improve regulatory compliance. Empirical findings indicate that blockchain-enabled SRM can improve material traceability, enable more accurate carbon accounting, and support circular economy strategies through transparent waste and recycling disclosures. The research reveals nuanced insights into stakeholder perceptions of trust, governance, and cost-benefit trade-offs, highlighting that successful implementation requires a phased roadmap, clear data ownership policies, standardized data schemas, and robust change management. The framework is validated through pilot implementations, where metrics such as cycle time reduction, defect rate changes, supplier score improvements, audit efficiency gains, and sustainability KPI progress are tracked over a 12-month horizon. Sensitivity analysis demonstrates the potential for substantial improvements in risk mitigation and supplier collaboration when transparency is coupled with incentive-aligned smart contracts. Policy implications and practical recommendations are provided for procurement leaders, suppliers, and technology providers, emphasizing the importance of pilot-driven scaling, regulatory alignment, and stakeholder engagement. The study concludes with a roadmap for future research to explore advanced governance mechanisms, cross-chain interoperability, and the integration of AI-augmented analytics to derive prescriptive insights from immutable supply chain data.

Project Overview

What This Project Is About

---

A plain-language overview of how purchasing and supply chains can benefit from digital records that are secure, transparent, and shared among trusted partners. The project explores how a system called blockchain can be used to manage relationships with suppliers, track purchases, and ensure processes comply with sustainability goals.

The Problem It Addresses

---

Many organizations struggle with opaque supplier information, inconsistent data, and limited visibility into where products come from. This leads to risks like fraud, non-compliance with environmental standards, and delayed decision-making. The project investigates how to improve trust, traceability, and accountability across buying and supplying activities.
