Abstract
Over recent years there has been an emergence of food scandals attributed to contaminations with chemical or microbiological hazards. In 2008, in China, ten dairy companies were found to add melamine, a nitrogen-based compound, into infant formula in an effort to artificially boost the protein content (1). Melamine is especially used in the production of plastic; thus, approximately 300,000 were affected, and six deaths were reported (1). These high numbers are attributed to the lack of tools the local authorities had to trace these contaminated batches, thus endangering the consumers’ lives for some time after the incident was discovered. There seems to be a general consensus that granting these tools would allow the guard against similar food scandals. Therefore, we can safely say that determining a product’s provenance at any point in the manufacturing lifecycle is one of the most critical issues that need to be addressed. Currently, there exists a limited number of solutions in both centralized in decentralized supply chains, in the form of applications and decentralized applications (dApps). In this paper, we focus more on the latter one. Whilst there are a few pilot programs that address the issue of provenance tracking, they fail to be accessible to the population suffering from disabilities or old-age. In addition, little to no-research has been done on features that improve the accessibility of their solution.
