课程概况
If you’re a software developer and new to blockchain, this is the course for you. Several experienced IBM blockchain developer advocates will lead you through a series of videos that describe high-level concepts, components, and strategies on building blockchain business networks. You’ll also get hands-on experience modeling and building blockchain networks as well as create your first blockchain application.
The first part of this course covers basic concepts of blockchain, and no programming skills are required. However, to complete three of the four labs, you must understand basic software object-oriented programming and how to use the command line. It’s also helpful, but not required, that you can write code in JavaScript.
When you complete the course, you should understand what a blockchain business network is, how to build and model a simple blockchain solution, and the role of the developer in creating blockchain applications.
If you choose to take this course and earn the Coursera course certificate, you will also earn an IBM digital badge upon successful completion of the course. You’ll need to pass several end-of-section quizzes and a final exam that include multiple choice, true and false, and fill in the blank questions.
This course does not cover Bitcoin or cryptocurrency in detail.
