Please read the following article "How blockchain improves the supply chain: case study alimentary supply chain" and prepare the questions. You should bring in your research findings and personal experience in using any services/products acquired through using any Internet and/or blockchain technology and systems/platforms. (A) The case study has suggested that the current "supply chain is a linear economy model that directly or indirectly fulfils supply needs" (p. 393). You are required to evaluate the strengths and weaknesses of the linear type of supply chain model. (B) The case study has argued that the widely implementation of blockchain will lead to the development and use of trustless supply chain networks. Critically evaluate this argument.

It is also suggested that blockchain can be very disruptive to the industry. Do you agree with these suggestions? You must give your reasons to explain why or why not.
