blockchain

Blockchain is like a digital ledger. It’s like a big list of all the things that have happened, like a log. Every time something new happens, it gets added to the list. All the items on the list are connected to each other which makes it impossible to change any of the items without changing the whole list. For example, in the blockchain world, when someone sends money to someone else, they put it in the blockchain ledger. That way, everyone can see it and verify that it happened. Blockchain is used for lots of things. For example, people use it to keep track of digital currency like Bitcoin, and it’s also used to protect data and secure online transactions. Fun Fact: Blockchain technology can be used to create digital identities for people, which could help reduce fraud and identity theft.
