About the Course:

Blockchain having wide impact and potential growth for change around the world. It is changing how business is executed. It's important to understand why Blockchain is different and how it works in comparison with technologies of the past.

Course Objectives:

  • Learn a conceptual view of Blockchain for the new applications that they enable.

  • Apply the Blockchain for various applications to provide a secure way of data access using cryptographic functions.

  • Learn various consensus mechanisms to implement for various real time applications.

  • Familiarize with the Blockchain deployment tools.

  • Learn various vulnerabilities and security mechanisms of Blockchain.

Course Outcomes:

At the end of this course, the student will be able to:

  • Analyze how the traditional databases can be replaced with Blockchain for the real time applications.

  • Integrate various cryptographic algorithms in to Blockchain.

  • Apply various consensus mechanisms to the real world Blockchain applications.

  • Evaluate the setting where a Blockchain based structure may be applied, its potential and its limitation.

  • Identify the threats of Blockchain and deploy security mechanisms.
