blockchain oracle

A blockchain oracle is kind of like a magic window or doorway that lets people on the blockchain (like Bitcoin) talk with people and things outside the blockchain. It works like a bridge between the blockchain and the rest of the world. It’s really helpful because it helps transactions on the blockchain be more secure because it can provide trustworthy information that can’t be forged or changed. For example, a blockchain oracle can tell the blockchain if an online payment was completed successfully, or if changes were made in a contract. It can also tell the blockchain about things that are happening in the real world, like the weather or stock prices. All of this extra information helps make sure the blockchain is safe and secure.
