ELI5: Explain Like I'm 5

Blockchain-based database

Okay kiddo, so imagine you have a toy box and you want to keep track of all your toys in there. A normal way to do that would be to write down a list of all the toys and which ones you have.

Now, think of a blockchain-based database as a very special way to keep track of all the toys in the toy box. It’s like having a magical friend who makes sure that no one can sneak in and take out or add any toys without everyone else knowing.

In this special database, all the toys are like blocks, and once they’re added to the database, they can’t be changed. Every time a new toy is added, a new block is created in the database and all the other blocks are linked together. This linking is what makes the database special because no one can sneak in and make any changes to the old toys without everyone else in the database knowing.

So, the people who use this database can be sure that every toy in the box is accounted for and no one can cheat by trying to make it look like they have more than they actually do.

Just like the toy box, this special database can be used for keeping track of other things too, not just toys. And because it’s so secure, lots of people and companies find it to be a really useful way to keep track of important information.
