TLDR; If you want to learn about privacy and how you can design your blockchain applications with privacy, I am working on a course which will go through the most widely used privacy techniques and add them to your applications in a very hands on fashion.

Privacy is very fundamental concept to developing blockchain applications, yet there are very little resources out there to learn from, especially knowing all the different techniques used for privacy and there pros and cons, also there is bias within different communities for privacy techniques if they have developed them or have any affiliation with them.

In this course, we want to look at all the privacy techniques and use them first hand to get a feel of when they should and should not be used, the idea is to keep it as simple as possible and develop some cool applications like rock paper scissors on blockchain and more to see how these privacy techniques can be used within your application.

Most of the time, Privacy is regarded as some moon math but the architecture of it is rather simple, take hashes for example, they are the recommended way to store user passwords and have great advantages but often they can be terrifying to software engineers, what hash function to use? how does it work and generally libraries fullfill these needs but we want to look under the blanket and see at a higher level what their properties are and why are they useful without going into maths rabbit hole. Also, just by knowing the various techniques of privacy, one can greatly benefit from them especially when implementing blockchain applications.
