  Blockchain technology truly opened the gate to a wave of unparalleled
innovations; however, despite the rapidly growing load of hype, the integration
into the business, apart from a few applications, seems to be coming at a
slower rate. One reason for that delay may be the need in the real-world
applications for the so-called trust model. Trust models are rarely mentioned
in blockchain application proposals despite their importance, which creates
skepticism about their successful developments. To promote trust model
implementation and help practitioners in its redaction, this article provides
an outline of what a trust model is, why it is essential, and an example of how
it is elaborated. The discussed example comes from a case study of a dairy
company that implemented blockchain for the traceability of its products.
Despite being tailored on a traceability project, the redaction and elements of
the trust model, with few adjustments, could be easily readapted for other
applications.
