Where there are people, there is a community, and where there is a community, there is struggle.
Under the rules#
The name of the train is becoming more and more well-known. One day, a few thieves secretly sneaked into the village under the guise of tourism.
"What is the train at the entrance of our village for? Why does everyone go to the entrance to get a piece of paper as soon as it's light out?" Xiao Hei (thief) looked at a group of villagers chatting under a crooked tree and casually asked as he approached.
"Hey, isn't it because a person named Satoshi Nakamoto said some things can be stored, so they won't be lost?"
"Yeah, things are put in containers where everyone can see them. It's great! I can easily find out who has my broom now by looking at the ledger."
"We get the piece of paper to calculate the password. Hey, I don't know either. My child calculates it every day. Their appetite has increased recently."
"Yeah, my child's appetite has also increased a lot. I heard that if you figure out this password, you can get a tip."
After chatting for a while, Xiao Hei roughly understood and also went to the entrance to get a piece of paper. Back in the house, he started studying with his accomplices:
"Boss, this piece of paper is the key to getting close to that train," Xiao Hei described the obtained information to his companions.
"This is just fooling people. It's purely based on guessing numbers. Whoever guesses correctly gets the money. I think we should go and study how the train is assembled while it's dark. After all, although we haven't dismantled a train, we have dismantled other equipment countless times."
"Good, let's go see what it is tonight."
The next day
Several people sat by the railway with panda eyes. "This tip seems to be generated out of thin air when connecting the carriages. Should we try replacing this connector with our own design to generate tips?" "Yes, this way we can connect the carriages ourselves. Let's go back and rest now. We'll work all night tonight and run early tomorrow morning."
...
On the third day, with the crowing of the rooster, the villagers saw that the train had mysteriously increased in length by two kilometers. The village chief went door to door asking what was going on, but no one knew...
The train conductor didn't know how to deal with these mysterious carriages either, so he could only let it develop. New carriages were added to the traceable carriages as a fork, and the villagers continued to develop on these new carriages.
PS: The broom example is unrealistic because the blockchain system is anonymous, so it is not possible to know who has it, at most, only an address can be known.
In August 2010, hackers carried out the first blockchain attack through the Bitcoin maximum integer overflow vulnerability, forcing BTC to undergo its first hard fork.
