Introduction
Hi, starting from this chapter, it's not like a development guide, it's more like my personal study notes and exploration for more advanced topics, starting from Cryptography, which builds the foundation of web3.
I have studied crypto in university, but very limited (They didn't really cover much practical concepts in real life like Digital Signatures) and I think I've returned most of my knowledge back to professors. But then I discovered Ethereum and I really studied hard about the concept of Digital Signatures (and through signing transactions in real life) and it turned out to be really easy. I think what I lack is the deeper mathematical understanding on some of the topics, and I was never bothered to understand real math behind what's really relevant to blockchains, that are Elliptical Curves and ZK. So this chapter should enhance my understanding on these topics, especially on EC and ZK. Hope they can make you "unstuck" on some of the concepts too.
This notes has included contents from Practical Cryptography for Developer and some external articles and Wikipedia (I think editors for crypto really make the study easier)
