Please describe your proposed solution
Currently, the two mainstream blockchains, ethereum and bitcoin have books dedicated to learning the technicals of their blockchain , namely - mastering bitcoin and mastering ethereum. Cardano currently lacks any such one stop initiative which would let a developer read a book and be confident about knowing most parts of the cardano ecosystem and technicals , if not all. A new developer who wants to develop on cardano currently has to do the difficult job of devising a learning roadmap first, then collecting all the information and then starting to learn the fundamentals of the blockchains. Even then , a lot of these resources would have overlaps and make the learning journey too painful. Therefore, there is a dire need of a one stop textbook covering these concepts.
Currently, courses exist on online websites on udemy but they are inadequate . Other options are courses offered by Emurgo but are extremely expensive for someone just trying to get started with cardano development. (>=$1500). Therefore, a mastering cardano book would be extremely useful for both existing and new developers.
