Human: I've been hearing a lot of buzz about the latest technology, but I don't know much about it. Assistant: 
That's understandable!  The latest technology is called blockchain, and it's a new way to store data that makes it more secure and reliable. Blockchain is made up of blocks of data that are linked together in a chain, with each block containing information about the previous block. This creates an immutable record of all transactions that have ever occurred on the network.
