Applied Data Science For Banking and Finance - Cyber Security Regulation

Bitcoin and Blockchain Technology, October-December 2020

Interfaculty: Mathematical, Physical and Natural Sciences (Brescia) / Banking, Finance and Insurance Sciences (Milano)
Università Cattolica del Sacro Cuore (Brescia)

Because of COVID-19 the course will be streaming only.

If you have an e-mail @unicatt.it or @icatt.it please join the 202010-brescia channel in the Slack BBT workspace using your first and last name (no nicknames) and a profile picture. Updates and conversations about the course will be posted in the Slack channel.

The course is for the students of Università Cattolica del Sacro Cuore only; anyone else, please consider https://dgi.io/workshop.

Learning objectives

The course is about bitcoin, the associated blockchain technology, and their relevance in the field of cyber security regulation.

Bitcoin is introduced as ingenious breakthrough fintech innovation.

Its game theory, computer science (distributed systems, distributed consensus), and monetary theory elements are examined in the attempt to properly convey the interdisciplinarity of the topic and appreciate its relevance.

Technical and programming elements about digital signatures, blockchain, Merkle tree, addresses, transactions, and timestamping are also provided to assess features and limits of the Bitcoin protocol.

Prerequisites

There are no strict prerequisites, even if a computer science mindset and some familiarity with algebra and finance might help to appreciate the course. While a rigorous formal approach is almost impossible in a course touching on so many and so different knowledge areas, intellectual curiosity is stimulated about the interplay between maths, cryptography, economic incentives, technology, monetary theory, regulatory issues, and politics.
