Abstract

Purpose This paper aims to investigate how blockchain has moved beyond cryptocurrencies and is being deployed to enhance visibility and trust in supply chains, their limitations and potential impact. Design/methodology/approach Qualitative analysis are undertaken via case studies drawn from food companies using semi-structured interviews. Findings Blockchain is demonstrated as an enabler of visibility in supply chains. Applications at scale are most likely for products where the end consumer is prepared to pay the premium currently required to fund the technology, e.g. baby food. Challenges remain in four areas: trust of the technology, human error and fraud at the boundaries, governance, consumer data access and willingness to pay. Research limitations/implications The paper shows that blockchain can be utilised as part of a system generating visibility and trust in supply chains. Research directs academic attention to issues that remain to be addressed. The challenges pertaining to the technology itself we believe to be generalisable; those specific to the food industry may not hold elsewhere. Practical implications From live case studies, we provide empirical evidence that blockchain provides visibility of exchanges and reliable data in fully digitised supply chains. This provides provenance and guards against counterfeit goods. However, firms will need to work to gain consumer buy-in for the technology following repeated past claims of trustworthiness. Originality/value This paper provides primary evidence from blockchain use cases “in the wild”. The exploratory case studies examine application of blockchain for supply chain visibility.

Analysis

Why This Paper Matters

This paper is significant because it moves blockchain research beyond theoretical or cryptocurrency contexts into real-world supply chain applications. By focusing on food supply chains, a domain where trust and provenance are critical, the authors provide grounded evidence of blockchain's potential and its practical hurdles. The work is timely given increasing industry interest in traceability and counterfeiting prevention.

The qualitative case study approach offers rich, contextual insights that quantitative methods might miss, such as the nuanced challenges of human error at system boundaries and consumer skepticism. This matters for AI practitioners because blockchain often integrates with AI for data integrity and automation; understanding these deployment barriers is essential for designing robust hybrid systems.

Technical Contributions

  • Demonstrates blockchain as an enabler of visibility in supply chains through live case studies.
  • Identifies four key challenge areas: trust in the technology itself, human error and fraud at system boundaries, governance of the blockchain network, and consumer data access combined with willingness to pay.
  • Provides empirical evidence that blockchain provides provenance and guards against counterfeit goods in fully digitized supply chains.
  • Shows that scalable applications are most likely for premium products where consumers pay extra (e.g., baby food).

Results

The paper does not provide quantitative metrics like accuracy or throughput. Instead, it offers qualitative findings: blockchain can generate visibility and trust, but firms must work to gain consumer buy-in following past claims of trustworthiness. The challenges identified are generalizable for the technology itself, though food-specific issues may not hold elsewhere.

Significance

This research has broader impact by directing academic attention to unresolved issues in blockchain deployment for supply chains. For AI practitioners, it highlights the importance of addressing human factors and governance when integrating blockchain with AI systems. The findings also inform practical decisions about where blockchain adds most value—namely, in high-value, trust-sensitive products.
