Query: Secure Blockchain-Based Supply Chain Management with Verifiable Digital
  Twins   A major problem in blockchain-based supply chain management is the unclear
validity of digital twins when dealing with digital representations of physical
goods. Indeed, the use of blockchain technology to trace goods is ineffective
if there is no strong correspondence between what is physically exchanged and
the digital information that appears in blockchain transactions. In this work
we propose a model for strengthening the supply chain management of physical
goods leveraging blockchain technology through a digital-twin verification
feature. Our model can be instantiated in various scenarios and we have in
particular considered the popular case of food traceability. In contrast to
weaker models known in the literature that propose their own ad-hoc properties
to assess the robustness of their supply chain management systems, in this work
we use the formalism of secure computation, where processes are described
through generic and natural ideal functionalities.
