This course is really a good start to understand basic of blockchain and cryptocurrencies. Since the course is quite old, after finish this course, I would recommend to study more in other resources.

This is a very detailed course for someone enough curious to start the Blockchain path. This content quality is very good and the information is transmited on a very effecient and profecient way.

Terrible course, it has absolutely nothing to do with the scope of the specialization (finance and strategy). The course goes entirely in boring, unintelligible and useless technicalities and computer concepts together with explaining the operation of programs and algorithms being suitable for a specialization in computer subjects but not for a program with a focus on finance and strategy. Duke must solve this type of errors since it puts its prestige at stake, it should eliminate this course from the specialization, or change the focus, lessons, tests and content towards a more practical and useful profile (show examples of practical uses of the technology and the potential business it can generate).

major problems in the grade section. some quizzes, tests or exams did NOT have a clear answer!! moreover a true/false question turned out wrong in both attempts - one time the answer true one time the answer false . please test and consider reconfiguration.

A largely incoherent mess. This course belabours many easy to grasp concepts in a scattergun approach but then airdrops references to irrelevant and complex notions. Its nether well thought out nor well targeted to any particular audience.
