So you want to deploy a blockchain but are overwhelmed by the sea of information out there that is half-baked and seems to want to do too much at the same time.
If so, this course is for you. We will start by explaining exactly what a blockchain is from a technical perspective instead of a high-level business overview. We start from absolute zero, assume no background and give the details only as much as necessary. Then, we move on to the highly popular and industry backed blockchain framework -- Hyperledger Fabric and its high-level library -- Composer. We explain how to set everything up and then move to creating our first blockchain and then a smart contract.
We will also cover how this blockchain can be used from an existing application using a REST API. This would enable you to start using blockchains in your own applications that can benefit from a blockchain or distributed ledger.
We take a case study-based approach and motivate why we need the commands we're running and how everything fits together. If there is a concept that is typically covered in similar courses but isn't immediately necessary for deploying our first smart contract, we'll skip it. We aim to have our first smart contract up and running in about an hour and then integrate with it from outside the Fabric environment by the end of this course -- a total of about 1.5 hours.
There is also a real-time chat system in place for students who enroll in this course. With a free signup, you get access to real-time chat with myself and fellow students who are working to complete this course (or have completed the course before you). We plan on creating this network of like-minded experts who can help each other out and collaborate on exciting ideas together.
What will I learn?
Basics of a hash
How this simple concepts enable the powerful blockchain architecture
Install and configure Hyperledger Fabric using the easiest method available
Install and run Composer -- a high-level, easy to use interface to Fabric
Set up a REST API to use our blockchain from outside Fabric
Use a REST API testing application and then PHP to access data from our blockchain

"I am just starting an internship, and the company is not 100% clear on what they are looking for, and I did not know much about the differences between Fabric and Composer, nor where to start. This was a lifesaver! And quick too!"
- Caleb Strong, student
"The instructor is very responsive, always tried to help in the issues I came across the way. I highly recommend for a good introduction ..."

I have a PhD in Computer Sciences and a PostDoc from the Max Planck Institute for Software Systems. I have been programming since early 2000 and have worked with many different languages, tools and platforms. I have an extensive research experience with many state-of-the-art models to my name. My research in Android security has led to some major shifts in the Android permission model.
I love teaching and the most important reason I upload online is to make sure people can find my content. If you have any problem with finances and you want to take my courses, contact me. I am more than willing to give out coupons that will make the course free for you.
