Have you ever played with building blocks, like Legos?
Imagine that there is a special kind of block that can hold information, like your name, your favorite color, or a picture you drew. And when you connect these special blocks together, they create a long chain of information!
That’s what we call a Blockchain. It’s a chain of blocks that stores information in a secure way. Each block has its own special code and is connected to the block before and after it, so nobody can change the information without everyone else knowing.
Just like how you can build lots of different things with Legos by putting different blocks together, people can use Blockchain to do lots of different things, like keeping track of money or voting in elections. It’s like a big, secure Lego tower that lots of people can work together to build!
