Metropolis

Metropolis is like a big city, with lots of buildings, cars, and people. Imagine you are in a game where you have to be the boss of this city, and every decision you make affects how the people in the city live.

In a game, you would have rules to follow, and everyone would play fairly. In Metropolis, there are also rules, but they are called protocols. These protocols are like a set of instructions that tell the computers in the network how to behave and work together.

But why do we need Metropolis? Well, it's because we want to be able to transfer digital money, like Bitcoin, without anyone cheating or stealing. With Metropolis, we can do this without a central authority. It's like everyone in the city working together to make sure that everything is fair and people can trust each other.

Metropolis is also designed to be safe from hackers, who may want to steal money or do other kinds of harm. So, just like in a game, we need to make sure that everything is secure and that nobody can cheat.

In summary, Metropolis is a virtual city where digital money can be transferred securely and fairly without any central authority, with the help of protocols designed to keep everything organized and safe.
