What is watchtower?

Watchtower is like having a super helpful friend who watches over your toys and makes sure no one messes them up when you're not looking.

Imagine you have a toy box full of your favorite blocks, cars, and action figures. You go to play with your friends, but when you come back, the toy box is all mixed up, your red car is hiding under a green block, and your robot is stuck in the middle of everything! That’s annoying.

Watchtower is like a special helper that keeps an eye on things while you're away. It checks if anything changes or gets messed up, and it tells you when it happens, so you can fix things before they get too chaotic.

Think of it like a robot guard who sits near your toy box all day long. If someone moves a toy or takes one without asking, the robot notices and sends you a message: “Hey, something changed in your toy box!”

This way, you always know if everything is where it should be, just like how your mom checks on your snacks before dinner!
