user42551: Can you please nominate a proper textbook about Bitcoin that covers the cryptographic tools utilized in Bitcoin?

user30732: REGARDING TEXTBOOKS ONLY:
The best one is Bitcoin and Cryptocurrency Technologies by Narayanan & Bonneau et al. 
You can get a draft version for free from Arvind Narayanan's blog.
The one by Andreas M. Antonopoulos, Mastering Bitcoin is good too. 
Roger Wattenhofer & Christian Decker et al also wrote a nice one called "The Science of the Blockchain" about blockchains in general.
