Chain code

Chain code is like a secret code used to keep track of things. It's like a game of memory, but lots of people can play it all at once. Think of it like a game of hide-and-seek. Everyone hides a little something (like a secret message or a special picture) and then gives out a special code word or phrase to the other players. Then, when someone finds the special something, they can tell everyone where to find it by using the special code they gave out. Chain code helps people keep track of things and be sure to only give out the secret stuff if they give out the correct code.
