After joining this forum, I discovered that I wasn't knowledgeable about bitcoin and having been doing research for a while in understanding bitcoin, now am more interested in going into the Technical aspects of Bitcoin, please I need resources to learn about bitcoin Blockchain Hash algorithm and also learning about cryptography as a whole .
It's great that you have decided to go deep into the technical aspects of bitcoin.
I have myself decided the same and have already started reading "Mastering bitcoin 2nd edition".
As others have already mentioned there's already a plethora of information available for us to grasp.
Fortunately, we have all the resources and it's just the time that we have to put into it to go in deep.
