What is blockchain? An article to understand the essence of blockchain

In view of my focus on blockchain, and many friends who follow me, they are not very clear about the nature and potential of blockchain, so I stayed away from it on the subway today and shared it with everyone.

Have you ever seen money?

Have you ever seen money? I believe you have never seen real money.

Is this money?

It's "notes", not money! This is not a word-picking, please listen to me in detail.

When someone borrows money from you, they give you an IOU. When they have money, you can use this IOU to exchange for your own banknotes. If he doesn't give it to you, you can still go to court and file a lawsuit to recover the money you owe!

As a worker, if you and your colleagues trust your boss enough, he can also give you IOUs and exchange them for banknotes at the end of the year. This is how many migrant workers are paid. During the Chinese New Year and holidays, they are paid based on accounting or IOUs.
But in theory, as long as the boss does not take into account his credibility and legal liability, he can issue countless IOUs until the incident comes to light.

So at this time, what is the difference between white strips and banknotes?

After issuing excessive IOUs, the courts will back you up; but after excessively printing money...wait for destruction!

Another example: meal tickets issued by the employer. This meal ticket will always be useful until the company goes bankrupt. In theory, you can print as many copies as you want until the company goes bankrupt.

This unit can be an enterprise or a country. In extraordinary times, banknotes can depreciate and become worthless, and become worthless if there is a change of dynasty.

So: IOUs, meal notes, banknotes, checks, and money orders are all the same thing, and they can be used as money, or they can be worthless.

Why does this happen? ? ?
It's a breakdown of trust

Bosses will run away, companies will go bankrupt, and the country will go bankrupt.

Real money is based on trust in "the most reliable thing".

What is the most reliable thing? In other words, who do you trust the most?
The “gods” in our culture, or ourselves.

Gods, shells and real money

In ancient times, we humans were weak and believed in gods and the destiny they gave us.
