If you have an e-mail please join the 202303-math 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 University of Milan (La Statale) only; anyone else, please consider

Learning objectives

The course is an introduction to bitcoin and the associated blockchain technology.

Starting from a computationally focused approach to elliptic curves over finite fields and presenting the discrete logarithm problem as the cornerstone of public-key cryptography, bitcoin is introduced as ingenious breakthrough 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.


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.
