Introduction

Recently, I tried to read the source codes of IBM hyperledger project to have a better understanding of blockchain. I found it a need to prepare myself with some knowledge in specific fields, like cryptography. And it turned out that writing was an effective way. It's not just about keeping track of what I have learned. Instead, as I tried to find a way to express myself more logically, those unintelligible ideas seemed to become less obscure. Those ephemeral thoughts just came out like a spring.😁 Really amazing, I should keep following it~ By the way, the notes are also available as gitbook html pages.
