Course Description

Decentralized blockchain-based systems, such as Bitcoin and Ethereum, are successful beyond all expectations. Although still in their infancy, they promise to revolutionize how we think of financial, information, and other infrastructures. This course covers the technical aspects of public distributed ledgers, blockchain systems, cryptocurrencies, and smart contracts. Students will learn how these systems are built, how to interact with them, how to design and build secure distributed applications.

Pre-Requisite/ Co-requisite/ Mutually Exclusive Subject(s)

The course assumes a basic familiarity with computer programming and knowledge of the Python language. Networks (50.012) and Security (50.020) are helpful but not required. Needed concepts will be introduced during the class.
