Challenges and Limitations

• Physical-Digital Gap Vulnerability: The link between physical products and digital records remains the weakest authentication point, as counterfeiters could potentially copy serial numbers or tags. QR codes face easy copying vulnerabilities, whilst even sophisticated NFC tags may succumb to advanced attacks. The “first-mile problem” recognises that blockchain trustworthiness depends entirely on initial data entry accuracy—fraudulent data entered during manufacturing persists immutably throughout the supply chain.
• Lack of Clear ROI: Many enterprises cannot demonstrate clear return on investment, making measurement difficult and creating long payback periods that may require years to materialise. Strategic business considerations reveal that double marginalisation through indirect blockchain platform sales can reduce brand-name firm profits, whilst lack of coordinated pricing may damage profitability regardless of technology capabilities.
• Scalability and Interoperability: Large-scale supply chain networks strain blockchain processing capacity, with some systems unsuitable for high-volume operations. Platform fragmentation creates established data-sharing protocol gaps, whilst legacy system integration requires substantial time and expertise. Different blockchains cannot easily communicate, and the supply chain management ecosystem lacks standardised interoperability frameworks.
• Implementation Reality: No major pharmaceutical companies have fully implemented blockchain programmes as of 2024, with many projects remaining in pilot stages. Fashion and apparel industry adoption pace remains fairly slow despite extensive discussion. Scaling from proof-of-concept to full production proves difficult, requiring network effects where value increases only when critical mass of participants join—demanding competitor collaboration and industry-wide standards agreement.
