Blockchain Technology and Cryptocurrencies

BAN435 Blockchain Technology and Cryptocurrencies

Autumn 2020

  • Topics

    Blockchain and Ethereum technology is the most disruptive force in years. The Ethereum is a cryptocurrency as Bitcoin's successor, evolving very fast and enabling businesses to build compelling solutions at a lower cost.

    The purpose of this course: learning about Blockchains, Ethereum and how to build smart contracts.

    Ethereum was created to facilitate applications focused around transferring money or value from one party to another. Solidity is a programming language for writing Smart Contracts and quite similar to Javascript. With Solidity, we can write applications that simulate a crowdfunding campaign, a lottery, a loan, or any other type of financial instrument.

    We will look at core technologies and some use cases for Blockchain and Ethereum technology:

    • What is Blockchain?
    • Why is Blockchain essential?
    • How is Blockchain different from traditional technologies?
    • Benefits of using Blockchain technology
    • What are the different Blockchain technologies?
    • What is Ethereum: Ether along with its units and Gas in Ethereum?
    • What are Smart Contracts and how do they work?
    • Use cases of Ethereum
    • Use cases of Smart Contracts

  • Learning outcome

    Upon successful completion of the course, the student will have attained the following:


    • Understand Blockchain basics
    • Comprehend what the blockchain and mining are
    • Understanding Ethereum: Ether, Gas and Ethereum Virtual Machine
    • Understand the fundamentals of smart contracts



    • Master Solidity and its basic concepts
    • Design, test, and deploy secure Smart Contracts
    • Use Ethereum development tools
    • Build compelling blockchain applications using the Ethereum Blockchain


    General competence:

    • can adjust to Ethereum no matter how the ecosystem changes

  • Teaching

    This course combines lectures and programming tutorials. A Mac, PC, or Linux Machine is required for students.

  • Recommended prerequisites

    A basic programming experience (preferably in Javascript)

  • Requirements for course approval

    Mandatory attendance and participation in 80% of class activities.

  • Assessment

    Multiple-choice Questions (MCQs) test

  • Grading Scale


  • Computer tools

    Remix: Develop Smart Contracts for the Ethereum Blockchain. Remix is a Solidity IDE that's used to write, compile and debug Solidity code.
