Guest speaker's talks (in class or in distance)

Students will have the chance to interact with experienced managers, executives and developers dealing with Bitcoin and Blockchain in order to discuss the main issues and trends in the field

Group assignments

A final group assignment will give students the opportunity to discuss among peers and collaborate in the development of a Blockchain application for a company

With the purpose of measuring the Course expected learning outcomes, the assessment for attending students, the exam will consist of an individual exam (50% of the final mark) + group assignment and presentation (40% of the final mark) + class participation and activities (10% of the final mark).

1. Individual exam: a questionnaire (composed of multiple-choice and open questions) on the theoretical part of the course, aimed at testing:
   1. their understanding of the key technical, economic and business aspects of blockchain-based cryptoassets;
   2. their knowledge about Bitcoin, Ethereum and Permissioned Blockchains;
   3. their understanding of the most relevant blockchain-based applications, their strengths and weaknesses.
2. Group assignment: it focuses on the second part of the course, specifically designed to measure the students’ ability to design a blockchain application tailored to a specific business context. Each project will be evaluated both from a technical and business perspective.   
3. Class participation: it will be crucial to acquire the ability to interact with executive and managers about the emerging trends and issues of blockchain in order to build an open and collaborative approach to the course’s topics.

The assessment for not attending students is based on a final written exam (100% of the grade). This exam will consist in:

1. a multiple-choice questionnaire on the course, aimed at testing
   1. their understanding of the key technical, economic and business aspects of blockchain-based cryptoassets;
   2. their knowledge about Bitcoin, Ethereum and Permissioned Blockchain;
   3. their understanding of the most relevant blockchain-based applications, their strengths and weaknesses.

2. Open questions aimed at testing their ability to analyze a blockchain-based solution from technical and business perspectives.

A collection of course readings will be made available in the course website through the University's elearning platform (Blackboard).
