Abstract
This vast research article outlines how blockchain technology is going to change supply chain management through deep analysis of over 150 global implementations and inter- views with more than 200+ industry leaders across 25 countries. Our findings have shown that blockchain technology reduces the cost of supply chains by 20-30% while improving traceability manifold times-75%-and decreasing documentation processing time by 85%. Through best practices-based quantitative and qualitative analysis, we provide in-depth implementation frameworks, ROI models, and technical architectures. Key findings in- clude the following: Organizations that adopt blockchain solutions achieve ROI within 18-24 months. Pharmaceutical sectors reduce counterfeits by as high as 85%, food safety has shown to recall products 73% faster, while authenticity verification in the luxury goods sector is 92% higher. This paper provides actionable insights in organisations at various stages in blockchain adoption, supported with comprehensive case studies and empirical data.
