0.前言

为了表达计算机科学的全局定位感，我将以SICP(Structure and Interpretation of Computer Programs)为内核，用故事的形式来进行重构。

故事的人物原型采用动画片：Rick & Morty

1.Rick & Morty

Morty家的车库是Rick的工作室。

木头桌子上，一个发光的立方体，电脑连着立方体，Rick盯着电脑。

“那是什么？” Morty问。

“我做的小宇宙。” Rick说，”给太空船当电池。”

“嗯…怎么有点不正常呢？“，Rick拿出两支蓝牙耳机：”从外面看不出问题，我们得进去一趟了。把这个插在耳朵里。

”这是什么？“，Morty问。

”MI （即，意识转换器，英文全称：Mind Interpreter），用来把我们的意识连入小宇宙。”，Rick说。

两人戴好MI，按下按钮，立刻失去了意识，倒在了地上。

2.BUG来自GC（垃圾回收器）

Rick和Morty恢复意识的时候，发现已经置身于一家咖啡馆，墙上写着Recreating Cafe。

牛头人端着咖啡，走过来：“Rick，你可来了！最近发生了一些可怕的事情。”

牛头人是宇宙联邦的通缉犯，为了不连累家族被灭，五年前自首，后被处死，自首之前，Rick帮牛头人把意识上传到了小宇宙之中，牛头人便在小宇宙中开起了咖啡馆。

“什么事？”Rick接过咖啡，品了一口：“ 嗯！牛头人，手艺又进步了！Morty快尝尝全宇宙最好喝的Recreating咖啡！”

Morty喝了一口，心想全世界的咖啡不都一个味吗。

牛头人没有等来Morty的赞叹，继续说：“大概一周前，一些人头顶会莫名的出现一个光环，几天之后，这些人会在同一个时刻…”牛头人打了个响指，“…就那么消失了！”

Rick瞪大了眼睛：“就像天使头上的那种光环吗？”

“对！对！就是那种！“

“Morty！快跑！这里不安全！”Rick摸着耳朵上的MI，按下了退出按钮。

Morty急忙学着做了同样的动作。

Core Concept Definition (核心观点定调)

既然要公开传播，我就对几个观点进行一下定调，免得被过分解读，下文所述比特币都是BSV。
Since it is going to be publicly distributed, I will adjust a few points of view so as not to be over-understood. Bitcoins described below are all BSV.

首先，法币体系的崩溃与比特币的出现没有必然因果关系，即使比特币不出现，现代法币体系也会自然瓦解和崩溃，...

Prologue

For great creation, recreating is worship.

Welcome to the world of Bitcoin !!!

WHAT is the book really about?
Position, concept position, concept position of Bitcoin.

WHY position?
Because the position is clear, understanding the natural occurrence.

HOW to position?
Find the WHY of the problem, give the solution, lead to the next problem, give the solution, and so on.

Vortex model
Inner ring: Problem/solution loop
Outer ring: Conceptual systems emerge naturally

Origin

How many complex must a man understand, before he can create a simple

1999, Midway, café.

Satoshi Nakamoto appeared in the seat by the window, just like he always did.

Satoshi liked this seat, not because of the view outside, but because of the power socket.

coding at cafe

Satoshi was a programmer. Recently he had been on vacation, coming here every day to write code. For him, the perfect...

Bitcoin v0.0.1

A week later, Satoshi completed the development of Bitcoin’s first version. Based on the plan before, he went to the closest computer store to buy a low-spec server and carried it to the cafe. He connected it online and installed the Linux OS. After he deployed the Bitcoin system, it was launched.

Then he purchased the domain name: www.bitcoin.org on GoDaddy and connected it to the IP address of Bitcoin’s server. Now Bitcoin could be accessed through the domain.

There came the obscure unveiling of Bitcoin to the world.

“Boss, Bitcoin is now up for use!” said Satoshi to Bob.

“Hah, great! Now, who wants to be the first in history to use Bitcoin?” asked Bob to the people in the cafe.

Alice answered back, “I will do it! It was inspired by me after all! I’ll get a latte with it. Lad, how do I go about using this?”

“You can open the website: www.bitcoin.org on your...

Prologue

Bitcoin’s first version had launched. The significance of this milestone is that it demonstrated the application of the system.

Cancelling the Account Model

Since the launch of Bitcoin v0.0.1, business of the cafe had been getting better and better. Bob obviously made a wise decision.

Satoshi, however, grew gradually more annoyed, “Too many people are coming to me to register account and exchange Bitcoin. I don’t even have time for coding. I need to think of another way. Maybe I can delegate the exchange work to Bob.”

Satoshi went to the cafe and asked Bob, “Hey Bob. A lot of people are coming to me for Bitcoin. Now I don’t have time for system upgrade. How about you handle the exchange work?”

“No problem! That works fine with me. But can I adjust the exchange rate?”

“Of course!”

Bob agreed happily. Satoshi told Bob his username and password. Bob’s cafe officially...

Prologue

The previous chapter mentioned symmetrical encryption, and we discovered that we didn’t need to encrypt the whole message in the transaction. Since transaction data can be read by the public, we only need to encrypt a small part of the transaction. What should be encrypt?

Signature

Since our fundamental purpose is not to prevent others from seeing the message in the transaction data, but to use the encrypted message to prove “I am I,” then my requirement is to encrypt as little text as possible. That is, the name of the sender of the encrypted message.

Why?

The inspiration originates from the real life. John wanted to buy a tractor, but he didn’t have enough money. So he needed to borrow $10,000 from Paul. Paul wanted an IOU from John, but John didn’t want to do that. In fact, John didn’t know how to write. Instead, Paul just wrote one for him: John owes Paul $10,000. But...

Public Key & Private Key

So how are the public key and private key of a user generated?

This is precisely the essence of asymmetrical encryption. User’s public key is derived from private key through computation, and user’s private key is counter-intuitively generated by the user themselves.

How is a private key generated?

Private key and public key in essence are numbers. If we treat any number as a private key, we can use elliptical curve cryptography to generate the corresponding public key of this number. That is, Function elliptical curve encryption (private key) = public key.

elliptical curve cryptography

If we let the user to randomly generate numbers and make the range of possibilities large enough, we can prevent two users from generating the same private key - that is, conflict of private key.

But then How large is large enough?

The answer is two to the power of...
