Imagine you and your friends are sharing toys, but no one is in charge. Every time someone takes a toy, everyone agrees on it, like writing it down together. Blockchain works the same way: people agree on things without needing a teacher or parent to check. ## What It Means A blockchain is like a shared notebook that keeps track of everything, and everyone has a copy of it.
Examples
- Your friends all agree on who took which toy, no need for a teacher.
- You write down that you gave a toy to your friend, and everyone copies it.
- If someone says they took a toy but they didn’t, the group checks the record.
