First Steps in Blockchain Learning with Chains
 |
Description
Book Introduction
Blockchain: The Real Story We've Missed
Uncovering the true nature of blockchain, obscured by the cryptocurrency investment craze.
"Blockchain is too complex to understand," "It's just a technology for coin investment," "Ultimately, it's a system controlled by someone," "The average person can't tell the difference between real and fake"? All of these are rooted in misunderstandings.
This book examines the blockchain from its original design by Satoshi Nakamoto to its current form, revealing the truth about blockchain that we have been missing, one by one.
In particular, through the real-world example of a chain (SASEUL) that has implemented 100% decentralization, it specifically demonstrates that a true blockchain is an independent system that no one can control.
In fact, understanding blockchain is not as difficult as you might think.
Anyone can distinguish between a real blockchain and a fake by simply understanding the three core concepts of consensus method, decentralization, and block storage method.
No technical background or investment experience is required.
By following the history and philosophy of blockchain and correcting the misconceptions prevalent in our society, you will soon gain a clearer understanding of what blockchain truly is.
This book will be a solid first step on that journey.

Publisher's Review
"What on earth is blockchain?"
I wrote this book to properly answer this question, which has been asked thousands of times.
Aren't you missing the essence of blockchain amidst countless misunderstandings and fragmented information? For those seeking to understand the true value and potential of blockchain, hidden behind the cryptocurrency investment craze and complex technical jargon, here's a clear introductory guide.
This book was written by the author, who has personally developed and operated blockchain technology, to address the numerous questions and misunderstandings he encountered in the field.
This book began with a sincere question: "How can we deliver accurate information to more people in a more accessible way?"
Rather than simply listing various projects, the author provides a three-dimensional explanation of the operating principles and philosophy, focusing on the real-world example of the blockchain "SASEUL," developed by himself.
By following one case in depth, you can get a full picture of blockchain technology.
We boldly avoid rigid technical jargon and complex formulas, conveying core concepts using everyday language and appropriate metaphors, making it accessible even to readers with no prior knowledge of blockchain.
Above all, it goes beyond simple technical explanations to answer fundamental questions like "Why does blockchain exist?" and "Why is this technology important?" It illuminates the inherent value and potential of blockchain as a "technology for people," transcending its degeneration into a speculative tool.
Between cryptocurrency investors and marketers, listen to the honest voices of real developers.
This will be the most certain first step in transforming vague curiosity into clear understanding and misinformation into correct knowledge.
In this rapidly changing technological era, I hope this book will provide you with insight that penetrates the essence.
