A blockchain is like a special notebook that many people can write in. Once something is written, it cannot be changed, and everyone can check that it was written correctly. This notebook help different people or companies work together by writing down and sharing important information in a safe and secure way.

Some people use these special notebooks to make digital money like Bitcoin. But it’s just way to use them. Companies also use these notebooks for other things, like making sure their business runs smoothly and securely.

So, the blockchain is not just about digital money, but also a to help people and businesses work together safely and fairly.
